LETTER OF TRANSMITTAL. 
 
 DEPARTMENT OF COMMERCE AND LABOR, 
 
 BUEEAU OF THE CeNSUS, 
 
 Washington, D. C, June 15, 1906 
 Sm: 
 
 I have the honor to transmit the Special Keport relating to the Blind and the Deaf, in 1900, compiled in 
 accordance with section 7 of the act of Congress of March 6, 1902. 
 
 The prehminary data for this report were collected by the enumerators of the Twelfth Census, who 
 reported the name, age, sex, and post office address of each person alleged to be blind or deaf, as a basis for a 
 more complete return to be secured by correspondence with the individuals. 
 
 The inquiry was initiated and the correspondence conducted under the direction of Dr. Alexander Graham 
 Bell, who determined the scope of the investigation and specified .the tabulations to be made from the data 
 secured. He also prepared the text relating to the deaf. In arranging the classification of the causes of blind- 
 ness. Doctor Bell was assisted by the late Dr. Swan M. Burnett, who kindly revised the comnaents relating 
 to this part of the work. The compilation of the statistical tables was performed in the division of vital statistics 
 under the supervision of the late William A. King, chief statistician for vital statistics. 
 
 The returns collected in connection with this inquiry have not only served as the statistical basis for this 
 report, but have been utilized to the more immediate advantage of the bhnd and deaf by preparing, upon 
 request, lists of addresses and personal data for schools, libraries, and other institutions estabhshed for the 
 benefit of these classes. Over 203 lists aggregating 42,084 names of blind persons and 29,544 of deaf have 
 been supplied by the Bureau of the Census, and it is believed that this use of the data will contribute more 
 directly to the personal benefit of the blind and deaf than any other that could be made. 
 Very respectfully.

 INTRODUCTION. 
 
 This report relates to the bUnd on June 1^ 1900. 
 Before discussing the results of the inquiry^ the method 
 pursued in the collection of the data should be ex- 
 plained. Heretofore census statistics of this class 
 have been based upon the complete return, by the 
 regular census enumerators, of all the details concern- 
 ing each individual enumerated, upon special schedules 
 designed for that purpose, and there has been no means 
 of determining the thoroughness of their canvass or the 
 accuracy of the returns made by them. 
 
 At the Twelfth Census, however, a change was made 
 in the plan for securing the returns, and the work of the 
 enimierators was restricted to a brief prehminary re- 
 turn showing only the name, sex, age, post office ad- 
 dress, and nature of the existing defects in all persons 
 alleged to be blind or deaf. The form of schedule fur- 
 nished the enumerators for this purpose, including 
 the instructions and explanations defining the defects 
 mentioned, is as follows : 
 
 TWELFTH CENSUS OF THE UNITED STATES. 
 
 SPECIAL SCHEDULE. 
 Persons defective in sight, hearing, or speech. 
 
 State Supervisor's District No 
 
 County - Enumeration District No 
 
 JownsMp or other division of county 
 
 Name of incorporated city, town, or village^ 
 within the above-named diHsion, j 
 
 , Enumerator. 
 
 INSTRUCTIONS. 
 
 The object of this special schedule is to obtain the name, sex, age, and post office 
 address of all persons who are either blind or deaf (including those who are deaf 
 and dumb) . 
 
 After completing the enumeration of all the members of a family on Schedule No. 
 
 1 (Form 7-224) , you will ask whether all the persons just enumerated have good 
 sight and good hearing— that is, can see well and hear well. For all such persons 
 no further inquiry need be made; but if you find that some member of the family 
 can not see well, you will then ask whether he or she can see well enough to read a 
 book; and should it appear that the sight is so seriously impaired that it is impos- 
 sible for the person to read a book, even with the aid of glasses, then you will note 
 such person as " Blind," even though, as a matter of fact, he or she may have some 
 slight power of sight. 
 
 In the same way, if you find that some member of the family can not hear well, 
 you will then ask whether he or she can hear well enough to understand loud con- 
 versation; and should it appear that the hearing is so seriously impaired that the 
 person can not be made to understand what people say, even when they shout, 
 you will note such person as " Deaf," even though, as a matter of fact, he or she 
 may have some slight power of hearing. You will then ask further whethet this 
 deaf person can speak; and should it appear that the person can not speak so as to 
 be understood, you will note such persons as " Deaf " and "Dumb," even though^ 
 as a matter of fact, he or she may have some slight power of speech. 
 
 Only those dumb persons who are deaf as well as dumb are to be noted ; so that if 
 you should come across dumb persons who are not deaf, they should not be included 
 nor should the '" semi-blind" and those blind only in one eye be reported on this 
 schedule. 
 
 For each person reported on this special schedule as blind or deaf you will write 
 on the population schedule (Form 7-224) , on the right-hand margin opposite the 
 name of any person defective as above, the letter " B " if the person is blind; the 
 letter"D" if the person is deaf; and the letters "DD" if the person is deaf and 
 dumb. If a person is blind and also deaf, use the letters " BD "; if blind and also 
 deaf and dumb, use the letters'' BDD," You will then make.the entries called for 
 on this special schedule, in columns 1 to 9, according to the following instructions : 
 
 In columns 1 and 2 enter the number of the sheet and of the line of the population 
 schedule (Form 7-224) on which the defective person is enumerated, and then copy 
 in columns 3, 4, and 5 the name, sex, and age of the person as originally entered on 
 that schedule. 
 
 In column 6 enter the post office address of the person reported as defective; or 
 if the person is a minor, or unable, through disability, to respond to communica- 
 tions by mail, obtain and enter in this column the name and post office address of 
 his or her parent, guardian, or nearest friend, using the two spaces as subdivided 
 by the dotted line. The intent of this inquiry is to secure the name and address of 
 the proper person from whom further information can be obtained by correspond- 
 ence concerning the blind and deaf persons enumerated. 
 
 In columns 7, 8, and 9 note the nature of the disability as follows: 
 
 If the person is defective in sight but can hear and speak, write " Blind " in col- 
 umn 7 and ''No" in columns 8 and 9. 
 
 If the person is defective in sight and hearing, but can speak, write '* Blind " in 
 column 7, "Deaf" in column 8, and "No" in column 9. 
 
 If the person is defective in sight, hearing, and speech, write " Blind " in column 
 7, "Deaf" in column S, and "Dumb" in column 9. 
 
 If the person is defective in hearing, but can see and speak, write "No" in col- 
 umn 7, "Deaf" in column 8, and "No^' in column 9. 
 
 If the person is defective in both hearing and speech, but can see, write " No " in 
 column 7, "Deaf" in column 8, and "Dumb" in column 9.

 Additional remarks, if any. 
 
 It is from the data contained in the personal sched- 
 ules returned to the Office that the appended tables 
 have been compiled. 
 
 The enumerators reported a total of 101,123 persons 
 alleged to be blind as defined in the instructions con- 
 tained in the schedules, but this number was greatly 
 reduced as a result of the correspondence directly with 
 the individuals, 8,842 reporting that the alleged defect 
 did not exist, and 6,544 that they were blind only in one 
 eye but were able to see with the other, and hence did 
 not come within the scope of the inquiry. No replies 
 were received in 19,884 cases in which personal sched- 
 ules were sent, although repeated inquiries were made; 
 consequently these cases were dropped. In 380 cases 
 the personal schedules returned were too incomplete 
 for use, and in 75 cases duplication was discovered. 
 The number eliminated for the reasons specified was 
 35,725. 
 
 It was also found that the defects alleged by the 
 enumerators did not, in many cases, agree with those 
 disclosed by the personal schedules. In 561 cases re- 
 ported by the enumerators simply as deaf or deaf and 
 dumb, blindness also was shown to exist, and in 1,196 
 cases in which blindness was alleged by the enumera- 
 tors there was no defect of vision disclosed by the per- 
 sonal schedules. 
 
 The result of the correspondence with the persons 
 alleged by the enumerators in their preliminary return , 
 to be blind, as set forth above, indicates that the ac- 
 curacy of statistics of this class based upon the enu- 
 merators' returns are likely to be seriously defective, 
 and that the personal particulars obtained by direct 
 correspondence with the individuals are much more 
 reliable. It also indicates that any comparisons with 
 the published statistics of 1890 would be misleading. 
 
 Much of the detailed information furnished in the 
 personal schedules is necessarily indefinite, particularly 
 that relating to the causes of blindness, which, being 
 stated in the language of the individuals, who are in 
 many cases ignorant of the facts or are illiterate, does 
 not permit a thoroughly scientific classification of the 
 causes of blindness. 
 
 The number of cases remaining for statistical treat- 
 ment, after making the eliminations and corrections 
 described, was 64,763, representing 35,645 totally blind 
 and 29,118 partially blind. This number, however, 
 can be considered only as the minimum, as an unknown 
 proportion of the blind were not located by the enumer- 
 ators, and doubtless a considerable proportion of the 
 19,884 persons who failed to return the personal sched- 
 ules should be included in the total. The number of 
 partially blind by no means represents the facts as to 
 defective eyesight among people, but so far as the 
 returns cover the field they represent verifed cases, 
 and possess a greater authenticity than any heretofore 
 secured. 
 
SUMMARY OF RESULTS. 
 
 Notwithstanding the probable deficiencies in the re- 
 turns the figures furnish a basis for determining, with 
 fair accuracy, the seat of the cause of blindness and the 
 relative frequency of different diseases of the eye pro- 
 ducing loss or impairment of vision. 
 
 SUMMARY OF RESULTS. 
 
 The principal facts concerning the blind set forth in 
 the general tables are those relating to sex, color, gen- 
 eral nativity, marital condition, present age and age at 
 which blindness occurred, causes of bhndness, and oc- 
 cupations. Consanguinity of parents, the number of 
 the blind having blind relatives, and the educational 
 advantages as indicated by school attendance are also 
 shown. 
 
 The general relation of these data to the blind, dis- 
 tinguished as totally and partially blind, is shown 
 briefly in the following tables and comments : 
 
 Sex.— Of the 64,763 blind reported, 37,054, or 57.2 
 per cent, are males, and 27,709, or 42.8 per cent, are 
 females, the number per 100,000 of corresponding 
 population being: Total, 85.2; male, 95.5; female, 
 74.5. The numbers, percentages, and ratios to popula- 
 tion are shown in relation to sex and degree of blind- 
 ness in Table i. 
 
 Regarding the degree of blindness, it is shown that 
 35,645, or 55 per, cent, of the blind are totally blind, 
 and 29,118, or 45 per cent, are partially blind. Of the 
 totally blind, 56.5 per cent are males and of the par- 
 
 tially blind, 58.1 per cent. To state these facts in 
 another way, blind males show a smaller proportion 
 of their number totally blind than do blind females, 
 the respective percentages being 54.4 and 55.9. The 
 number of totally blind per 100,000 of total popula- 
 tion is 46.9; in the male population, 51.9; and in the 
 female population, 41.7. The corresponding numbers 
 per 100,000 for the partially blind are 38.3, 43.6, and 
 32.8, respectively. These figures indicate that blind- 
 ness, both total and partial, is more common among 
 males than females.

 Color. — The number of white persons returned as 
 bHnd is 56,535, of which 30,359 are totally blind and 
 26,176 are partially blind. The number of colored 
 blind is 8,228. This includes 7,646 negroes, 568 
 Indians, and 14 Chinese or Japanese, which, in the 
 tables, are grouped under the caption "colored." Of 
 the 8,228 colored, 5,286 are totally blind and 2,942 par- 
 tially blind. The numbers, with the percentages of 
 each class, and the number per 100,000 of corre- 
 sponding population are shown in Table iii. 
 
 The figures in the following table show that of the 
 blind whites, 53.7 per cent are totally blind and 46.3 
 per cent are partially blind. Of the colored blind, 
 the per cent totally blind is much greater, being 64.2; 
 while the per cent partially blind is correspondingly 
 less (35.8). The number of blind per 100,000 is 
 greater in the colored population (89.6) than in the 
 white (84.6). The number of totally blind per 100,000 
 
 is also greater among the colored than among the 
 whites, but the number of partially blind per 100,000 
 is smaller.

 THE BLIND. 
 
 The relation of color to blindness is shown in the 
 following general tables: 
 
 Table 1 gives details of color, nativity, and age. 
 
 Table 3 gives details of color, nativity, age, sex, and 
 age when blindness occurred. 
 
 Table 8 gives details of color, nativity, cause of 
 blindness, and sex. 
 
 Table 12 gives details of color, school attendance, 
 sex, and age. 
 
 Table 13 gives details of color, school attendance, 
 and age when blindness occurred. 
 
 Table 15 gives details of color, age, sex, and occupa- 
 tions. 
 
 Nativity of the blind whites. — Of the 56,535 blind 
 whites, 45,479 are native born and 10,694 are of for- 
 eign birth. The number and per cent of each class, 
 by degree of blindness, and the number per 100,000 of 
 corresponding class of population, are shown in Table v.

 ■From these figures it appears that a smaller propor- 
 tion of the blind are totally blind among native whites 
 (52 per cent) than among foreign born whites (60.9 
 per cent) . 
 
 The number of blind per 100,000 of population is 
 considerably greater among the foreign born white 
 population than among the native white (foreign born 
 whites, 104.7; native whites, 80.4). The diilerence 
 is more marked for the totally blind (foreign born 
 whites, 63.7; native whites, 41.8) than it is for the 
 partially blind (foreign born whites, 41; native whites, 
 38.6). 
 
 The greater proportion of blindness among the for- 
 eign born whites, as compared with the native whites, 
 is due to the difference in the age distribution of the 
 two classes, 46.5 per cent of the foreign born white 
 population being over 40 years of age, while 49.5 per 
 cent of the native white population is under 20 years 
 of age. The differences in the proportions for the 
 native and the foreign born whites are further ex- 
 plained in the discussions under "ages of the blind" 
 and "age at which blindness occurred." 
 
 The relation of nativity to blindness is shown in the 
 following general tables: 
 
 Table 1 gives details of nativity, color, and agte. 
 
 Table 3 gives details of nativity, color, age, sex, and 
 age when blindness occurred. 
 
 Table 8 gives details of nativity, color, causes of 
 blindness, and sex. 
 
 Age. — Blindness, either total or partial, is so largely 
 a defect of the aged, and occurs with so much greater 
 frequency as the age advances and the population 
 diminishes, that in any. comparison of the proportion 
 of the blind in the general population of different 
 classes, such as native and foreign born whites, or 
 white and colored, the age distribution of the popula- 
 tion of each class should be constantly borne in 
 mind. The differences in this respect account for 
 many of the differences in the gross ratios, and it is 
 only when ratios are compared for classes of popula- 
 tion of identical ages that their relative liability to 
 blindness can properly be inferred. 
 
 The proportion of the general population of the 
 stated classes of each age, per 100,000 of all ages, is 
 shown in Table vi.

 The figures given in Table vr show that the propor- 
 tions of the native white and the colored population 
 comprised in the specified age groups are very similar, 
 while the proportions of foreign born whites at ages 
 above 20 years greatly exceed those of the native 
 whites; the proportion of foreign born whites between 
 60 and 80 years of age— the period in which blindness 
 most frequently occurs— being nearly three times that 
 of the native whites (foreign born whites, 13,678 per 
 100 000; native whites, 4,779 psr 100,000). 
 
 Table vii shows the classification, by degree of blind- 
 ness, of the blind under 20 years of age, 20 years of age 
 and over, and of unknown age, with respect to color 
 and nativity, with the number at the specified ages 
 per 100,000 of population in the same age group.

 It will be seen from Table vii that among the blind 
 under 20 years of age the number of totally blind is 
 practically the same as the number of partially blind — 
 4,123 and 4,185 being the respective numbers. But 
 among the blind 20 years of age and over the totally 
 blind are much more numerous, the number of totally 
 blind being 31,363 and of partially blind, 24,802. 
 
 It will also be seen from the preceding table that the 
 number of totally blind under 20 years of age per 
 100,000 population of corresponding age is practically 
 the same for native whites, foreign born whites, and col- 
 ored, thenumbers being, respectively, 12.1, 12, and 12.6. 
 In the group 20 years of age and over the number 
 totally blind per 100,000 of population is about the 
 same for the native whites (70.8) and the foreign born 
 whites (69.8) , but is considerably greater for the colored 
 (103.3) than for either class of whites. 
 
 The number of partially blind per 100,000 of popu- 
 lation in the age group under 20 years is greatest for 
 the native whites (12.7), least for the foreign born 
 whites (9.5), and intermediate for the colored (10.3). 
 About the same relative difference occurs in the pro- ' 
 portions for the group 20 years of age and over (native 
 whites, 63.9; foreign born whites, 44.5; colored, 54.1). 
 
 Table viii shows the number of the blind, by present 
 age and degree of blindness, and the number at each 
 age per 100,000 of corresponding age.

 The proportion of the population totally or partially 
 blind, as shown in the .above table, increases steadily 
 with advancing years. In the age group 10 to 19 years 
 there are more persons partially blind (20.1 per 100,000) 
 than totally blind (18.3 per 100,000), but in all other 
 age groups the totally blind exceed the partially blind. 
 
 Table ix shows the number of blind under 20 years 
 of age, 20 years of age and over, and of unknown age in 
 each state and territory, with the number of each speci- 
 fied age per 100,000 of corresponding population.

 The relation of age to blindness is shown in the fol- 
 lowing general tables : 
 
 Table 1 gives details of age, color, and nativity. 
 
 Table 2 gives details of age, and age when blindness 
 occurred. 
 
 Table 3 gives details of age, color, nativity, sex, 
 and age when blindness occurred. 
 
 Table 12 gives details of age, color, sex, and school 
 attendance. 
 
 Table 15 gives details of age, color, sex, and occu- 
 pations. 
 
 Age when blindness occurred. — The age at which 
 blindness occurred has a most important bearing upon 
 the statistics showing the relation of other factors to 
 blindness; but the nature and development of the disa- 
 bility in certain cases prevent an accurate statement of 
 the age at which it occurred, and where the exact age 
 could not be given the individuals were requested 
 to indicate the approximate age by specifying the 
 period of life, as infancy, childhood, youth, adult life, 
 or old age. 
 
 This permits the subdivision of age of occurrence 
 into two broad groups — under 20 years and 20 years 
 and over — which have been used in all of the tables 
 showing the age at which blindness occurred. 
 
 Table x shows, by degree of blindness, the number 
 who became blind in the specified age periods, and the 
 number in each age period per 1,000 blind of all ages.

 The figures in Table x include the foreign born 
 whites, for which class the number who became blind 
 under 20 years of age is inadequately represented, as 
 the disability prevents their immigration; the propor- 
 tions under 20 years are therefore somewhat too low, 
 and those for 20 years and over are somewhat too high. 
 
 Table xi shows, by degree of blindness, the number 
 who became blind at the specified ages, and the number 
 who became blind at each age per 1,000 blind of all 
 ages. 
 
 It will be seen from the figures that of the totally 
 blind, 2,317, or 65 per 1,000, have been blind from birth, 
 and that 2,084, or 58.5 per 1,000, became blind after 
 birth but under 2 years of age. Of the partially blind, 
 2,413, or 82.9 per 1,000, are blind from birth, and 1,352, 
 or 46.4 per 1,000, became blind before reaching 2 years 
 of age. Thus the number who lost their sight, either 
 entirely or partially, before reaching the age of 2 years, 
 is 8,166, or 126.1 per 1,000 of the blind at all ages.

 The proportion of congenital blind, or blind from 
 birth, is greater among the partially blind (82.9 per 
 1,000) than among the totally blind (65 per 1,000) ; so, 
 too, is the proportion that became blind under 5 years 
 of age — 170.1 per 1,000 of the partially blind and 163.3 
 per 1,000 of the totally blind. But the proportion that 
 became blind in each age period above 5 years of age 
 is greater among the totally blind than among the 
 partially blind. 
 
 The relation of age or period of life when blindness 
 occurred is shown in the following general tables: 
 
 Table 2 gives age of the blind and age when blind- 
 ness occurred. 
 
 Table 3 gives present age, sex, color, and nativity of 
 the blind and age when blindness occurred. 
 
 Table 4 gives the age when blindness occurred. 
 
 Table 5, in greater detail than Table 4, gives the 
 age when blindness occurred. 
 
 Table 6 gives the data similar to those in Table 5, 
 with greater detail as to age when blindness occurred. 
 
 Table 7 gives the age when blindness occurred, sex, 
 and marital condition. 
 
 Table 10 gives the age when blindness occurred and 
 causes of blindness. 
 
 Table 13 gives the age when blindness occurred, 
 color, and school attendance. 
 
 Tables 14 and 16 give the age when blindness oc- 
 curred and occupation. 
 
 Table 17 gives the age when blindness occurred and 
 age when deafness occurred.

 Causes of blindness. — In classifying the causes of 
 blindness for statistical compilation it was considered 
 desirable, and at the same time scientific, to arrange the 
 causes, as far as possible, according to the anatomical 
 
12

 divisions of the eye. For example, under "opacity 
 of the eye ' ' have been classed all diseases of the cornea, 
 stated as such, and also cases attributed to granulated 
 lids, and all other diseases of the conjunctiva indicated 
 by such causes as measles, scarlet fever, scrofula, small- 
 pox, and sore or inflamed eyes, since these causes do not 
 usually impair vision except when the cornea is affected. 
 
 In the same manner, diseases of the iris, ciliary 
 body, and choroid have been inferred as the causes 
 of blindness in cases reported as due to venereal dis- 
 ease (syphilis), exposure to heat or cold, rheumatism, 
 etc., since these diseases of the eye generally result 
 from the causes mentioned. 
 
 Affections of the nervous apparatus, either in the 
 eye itself or the cerebral region, have been considered 
 the causes of blindness in cases attributed to strained 
 eyes, errors of refraction, meningitis, and diseases of 
 the brain. 
 
 Of the 64,763 cases reported, 41,874, or about 65 
 per cent, became blind from the classified causes. 
 
 Other causes, such as "congenital," "mihtary serv- 
 ice," "hereditary," "grip," "fever," "accidents," and 
 " different cause for each eye," etc., which do not come 
 specifically within the classes described, have been 
 grouped as "unclassified." These number 14,885, or 
 23 per cent of the total. 
 
 In 8,004 cases, or about 12 per cent of the total, the 
 cause was either reported as unknown or so indefi- 
 nitely stated as to preclude classification under any 
 other title. 
 
 Table xii gives the complete classification adopted, 
 with the number of blind from each cause and class, 
 by degree of blindness. 
 
 In the general tables the list of causes has been some- 
 what condensed, the classification being specified in 
 Table xiii, which shows, by degree of blindness, the 
 number blind from each cause, the number blind 
 from each cause per 1,000 blind from all causes, and 
 the per cent totally and partially blind from each 
 
 cause.

CAUSES OF BLINDNESS. 
 
 13 
 
 It will be seen from Table xm that of the specific 
 causes of blindness, those to which the greatest propor- 
 tion of cases per 1,000 from all causes is due are : Cata- 
 ract (121.4), injuries, accidents, and operations (103.3), 
 congenital (73), old age (60.3), and sore eyes (57.7). 
 Unknown causes are responsible for a slightly greater 
 proportion than any of the above, namely, 123.6 per 
 1,000. 
 
 Considered with reference to the degree of blindness, 
 the percentage totally blind is considerably greater 
 than that partially blind when the defect is due to the 
 following causes: Meningitis (80.8), glaucoma (76.4), 
 congestion, or disease, of brain (73.7), scarlet fever 
 (72.5), smallpox (71.2), venereal diseases (67.7), in- 
 juries, accidents, and operations (66.7), neuralgia 
 (65.5), grip (61.5), and colds (61.2); while the per- 
 centage partially blind is greater in the cases due to 
 granulated lids (69.4), old age (63.4), scrofula (60), 
 catarrh (55), measles (54.3), and military service (51.1). 
 
 Table xiv shows for each color, by degree of blind- 
 ness, the number blind from each cause per 1,000 blind 
 from all causes. The figures show that the causes 
 resulting in a greater proportion of blindness among 
 the whites than among the colored were : Granulated 
 lids (white, 20.1; colored, 3.8); catarrh (white, 8.5; 
 colored, 6.2); colds (white, 13.5; colored, 6.4) ; measles 
 (white, 23.8; colored, 12.9); scarlet fever (white, 10.8; 
 colored, 1.5); smallpox (white, 7.3; colored, 6.4) ; cata- 
 ract (white, 127.1; colored, 82.3); neuralgia (white, 
 27.9; colored, 22.2); glaucoma (white, 15.9; colored, 
 3); meningitis (white, 10.4; colored, 8.9); congestion, 
 or disease, of brain (white, 7.7; colored, 4.1); congeni- 
 tal (white, 74; colored, 66.5); military service (white, 
 39.1; colored, 22.3); and grip (white, 12.5; colored, 
 7.8). 
 
 Attention is drawn to the great disparity between 
 the white and colored in the occurrence of blindness as 
 the result of granulated lids and glaucoma. The 
 figures confirm the opinion, generally held by observ- 
 ers in America, that granulated lids, or trachoma, 
 which is so fruitful a cause of blindness among the 
 Irish, the Russians, the Jews, and the Italians, is 
 almost unknown among the negroes in this country. 
 
 The causes producing a greater proportion of blind- 
 ness among the colored than among the whites were: 
 Scrofula (colored, 26.7; white, 16.7); sore eyes (col- 
 ored, 61.3; white, 57.2); venereal diseases (colored, 
 9.6; white, 2.6); exposure to heat and cold (colored, 
 
 11.2; white, 6.7); old age (colored, 92; white, 55.7); 
 injuries, accidents, and operations (colored, 107.7; 
 white, 102.6); strained eyes (colored, 25.5; white, 
 19.5); and unknown causes (colored, 186.7; white, 
 114.4).

 It will be seen from Table xvi that causes affecting 
 the cornea caused blindness in a larger number of 
 cases among those blind from childhood than among 
 the blind from adult life. Causes affecting the iris, cil- 
 iary body, and choroid, and causes affecting the lens 
 produce blindness principally among adults; likewise 
 other causes producing opacity of the eyes. Affections 
 of the nervous apparatus cause blindness about as often 
 among those under 20 years of age as among adults. 
 
MARITAL CONDITION. 
 
 15 
 
 Of the 20,704 persons who were blind from childhood, 
 4,728 were born blind — about 23 per cent — the other 
 principal causes being injuries, accidents, and opera- 
 tions, 2,295; sore eyes, 1,753; cataract, 942; measles, 
 841; scrofula, 725. 
 
 Cataract, injuries, accidents, and operations, old age, 
 affections of the nervous apparatus, military service, 
 sore eyes, and neuralgia were the principal causes of 
 blindness among adults. 
 
 The detailed ages at which blindness occurred, con- 
 stituting the two broad age groups specified in Table 
 XVI, are given, in relation to causes of blindness, in 
 Table 10, and an examination of that table shows that 
 of the totally blind, 3,935 were blind at birth or became 
 so under 1 year of age, while for the partially blind the 
 corresponding figures are 3,434. These 7,369 persons, 
 whose vision was either totally lost or seriously impaired 
 before the completion of the first year of life, represent 
 11.4 per cent of the total number of blind. 
 
 Excluding congenital defects and injuries, accidents, 
 and operations there are 2,556 who lost sight after birth 
 but under 1 year of age, and in 644, or 25.2 per cent, of 
 these cases the cause of blindness was probably ophthal- 
 mia neonatorum, or " babies' sore eyes," since other dis- 
 eases of the eye causing blindness under 1 year of age 
 are extremely rare. The importance of these figures 
 lies in the fact that this disease, which is very malig- 
 nant and which attacks the infant at birth or immedi- 
 ately after and alniost always results in total destruc- 
 tion of the sight — usually of both eyes — or in very 
 seriously impaired vision, is now considered preventa- 
 ble, and if proper measures had been instituted at the 
 time of birth few or none of these cases would have 
 occurred. 
 
 It is not pertinent in this connection to discuss the 
 means of prevention, which are well known, but it can 
 at least be pointed out, with emphasis, that the so- 
 called ' 'sore eyes " of babies is a highly dangerous affec- 
 tion, and that its treatment should be prompt and 
 energetic and carried out by a thoroughly competent 
 person. 
 
 The relation of causes of blindness to other details is 
 shown in the following general tables: 
 
 Table 8 gives the causes of blindness, color and nativ- 
 ity, and sex. 
 
 Table 9 gives causes of blindness. 
 
 Table 10 gives causes of blindness and age when 
 blindness occurred. 
 
 Table 11 gives causes of blindness, consanguinity of 
 parents, and classes of blind relatives. 
 
 Marital 'condition. — Of the 64,763 blind reported, 
 22,120 are single, 24,559 are married, 17,333 are wid- 
 owed, 379 are divorced, and for 372 the marital condi- 
 tion is not stated. Table xvii shows, by degree of 
 blindness, the number and per cent of the blind in each 
 marital class, with the number per 100,000 of each mar- 
 ital class of the population.

 The figures in Table xvii are based upon the blind 
 of all ages. On this basis the percentages of the blind 
 by marital condition are: Single, 34.1; married, 37.9; 
 widowed, 26.8; and divorced, 0.6. There is a much 
 larger proportion of the partially blind than of the 
 totally blind married, while the reverse is true of the 
 single. 
 
 The numbers per 100,000 of population show that of 
 the entire unmarried population 50.3 in each 100,000 
 are blind, 29.8 being totally blind and 20.5 partially 
 blind. Of the married, 88.4 per 100,000 are blind; of 
 the widowed, 444.9 per 100,000 are blind; and of the 
 divorced, 190.5 per 100,000 are blind. 
 
 The excessive proportion of blind among the wid- 
 owed or divorced population is due to the fact that the 
 ages of the widowed and the divorced are much higher 
 than those of the single and the married, and the further 
 fact that the disability occurs with increasing fre- 
 quency as the age increases. It also operates, to a 
 certain extent, as a bar to remarriage. 
 
 In comparing results concerning the marital condi- 
 tion of different classes of the population, those under 
 15 years of age are generally excluded as almost wholly 
 single or as unqualified for marriage. Making this 
 exclusion in both the blind and the general population, 
 the proportions of single, married, widowed, and di- 
 vorced in the two classes are as follows:

 In making deductions from the above table the 
 marked difference already referred to between the age 
 distribution of the blind and that of the total popula- 
 
16 
 
 TH^ BLIND. 
 
 tion must be borne in mind. The fact that the pro- 
 portion of blind in the population increases very rap- 
 idly with each successive age period, especially after 
 50 years of age (Table viii), is doubtless the prin- 
 cipal reason for the large proportion of widowed and 
 the small proportion of single among the blind, as 
 compared with the total population. 
 
 Excluding those under 15 years of age the number 
 of unmarried blind per 100,000 of , population is 94.8 
 (totally blind, 58.8; partially blind, 36). This exclu- 
 sion does not affect the proportions of blind among the 
 married, widowed, or divorced in any appreciable de- 
 gree, as the number of these classes under 15 years of 
 age is so small as to be negligible. j 
 
 The relation of marital condition to blindness is 
 shown in Table 7. 
 
 Consanguinity of parents, and blind relatives. — The 
 relationship or consanguinity of the parents of the 
 64,763 blind was reported in 56,507 cases, in 2,527, or 
 4.5 per cent, of which the parents were related as 
 cousins. 
 
 In 57,726 cases the inquiry as to the existence of 
 blind relatives was answered; 10,967, or 19 per cent, 
 of this number reported that they had blind relatives. 
 
 The blind relatives are divided into two groups — 
 the first comprising blind brothers, sisters, or ances- 
 tors, and the second collateral relatives or descendants. 
 The results are shown in Table xviii.

 Of the 2,527 blind persons whose parents were cous- 
 ins, 993, or 39.3 per cent, have blind relatives — 844 
 having blind brothers, sisters, or ancestors, and 149 
 having blind collateral relatives or descendants. Of 
 the 53,980 blind whose parents were not related, 9,490, 
 or 17.6 per cent, have blind relatives, 7,395 having 
 blind brothers, sisters, or ancestors, and 2,095 having 
 blind collateral relatives or descendants. 
 
 Considered with reference to the degree of blindness 
 the figures show that 1,291, or 51.1 per cent, of those 
 whose parents were cousins are totally blind, and 1,236, 
 or 48.9 per cent, are partially blind. Of those whose 
 parents were not related, 29,892, or 55.4 per cent, are 
 totally blind, and 24,088, or 44.6 per cent, are partially 
 blind. It appears from these figures that total blind- 
 ness occurs with somewhat greater frequency among 
 those whose parents were not related.

 relatives.

 The most significant fact derived from the figures 
 given in Table xix is found in the showing that of the 
 2,527 bUnd whose parents were cousins, 632, or 25 per 
 cent, are congenitally bhnd, of whom 350, or 55.4 per 
 cent, also have blind relatives of the classes specified; 
 while among the 53,980 whose parents were not so 
 related the number of congenitally blind is 3,666, or 
 but 6.8 per cent, of whom only 1,023, or 27.9 per cent, 
 have blind relatives. 
 
 The only specific causes other than congenital, to 
 which a greater proportion of the total cases of blind- 
 ness among those whose parents were cousins than 
 among those whose parents were not related is due, 
 are: Catarrh (parents cousins, 9.1; parents not cous- 
 ins, 8.7 per 1,000); scarlet fever (parents cousins, 10.7; 
 parents not cousins, 10.1 per 1,000); scrofula (parents 
 cousins, 28.1; parents not cousins, 19 per 1,000); and 
 measles (parents cousins, 28.9; parents not cousins, 
 23.5 per 1,000). The difference in "these proportions 
 is but slight, and the relative number of cases of blind- 
 ness attributed to each of the other causes is greater 
 among those whose parents were not related. 
 
 Table 11 gives the number of blind, by causes of 
 blindness, consanguinity of parents, and classes of 
 blind relatives. 
 
 School attendance. — The inquiry concerning educa- 
 tion of the blind was limited to the simple question of 
 whether the person had attended school, and if so, the 
 kind of school attended, as "special school for the 
 blind," or "common school," "high school," "col- 
 lege," etc. 
 
 Table xx shows the number and per cent of cases 
 in which the totally and partially blind of each color 
 returned a definite answer to the inquiry regarding 
 school attendance.

 The question was answered in 53,582 cases, and the 
 replies_show that 24,556, or 37.9 per cent, of the whole 
 
 number of blind have a greater or less amount of 
 schooling, while 29,026, or 44.8 per cent, have not 
 attended any kind of school. In 11,181 cases, or 17.3 
 per cent, the information was not supplied. 
 
 Of the totally blind, 12,927, or 36.3 per cent, have 
 attended school, and 17,141, or 48.1 per cent, have 
 not. Of the partially blind, 11,629, or 39.9 per cent, 
 have attended school, while 11,885, or 40.8 per cent, 
 report no schooling whatever. 
 
 The number and per cent of the white and colored 
 blind, classified by degree of blindness, who have re- 
 ceived instruction in special schools for the blind is 
 shown in Table xxi.

 The detailed information with respect to school- 
 ing of the blind is contained in the following general 
 tables : 
 
 Table 12 shows the. blind, by color, school attend- 
 ance, age, and sex. 
 
 Table 13 shows the blind, by color, school attend- 
 ance, and age when blindness occurred. 
 
 Occupations. -^Oi 62,456 blind 10 years of age and 
 upward, 12,506, or 20 per cent, were reported as en- 
 gaged in definite remunerative occupations. The 
 per cent of the general population similarly em- 
 ployed was 50.2. 
 
 Classifying the occupied blind by degree of blind- 
 ness, the number reported as totally blind is 5,581 
 and the number reported as partially blind is 6,925. 
 In other words, 16.2 per cent of the totally blind 10 
 years of age and over are gainfully employed and 24.7 
 per cent of the partially blind. 
 
 The occupations of the blind were compiled ac- 
 cording to the classification adopted for the total 
 population, and the number of the blind, classified 
 by degree of blindness, engaged in the general classes 
 of occupations, with the percentage that each class 
 forms of those gainfully employed- are shown in Table

 The per cent distribution of the general popula- 
 tion gainfully employed, by classes of occupations, for 
 comparison with the preceding results obtained for 
 the blind, is as follows:

 The preceding figures show that there is a larger 
 percentage of totally blind persons gainfully employed 
 engaged in professional pursuits, trade and trans- 
 portation, and manufacturing and mechanical in- 
 dustries than is found in the general population, 
 while the percentage engaged in agricultural pur- 
 suits and domestic and personal service is less. Of 
 the partially blind gainfully employed, the majority 
 follow agricultural pursuits, the percentage in this 
 class (55.6) being higher than that in the general 
 population (35.7). 
 
 Comparing the proportions that those engaged 
 
 each class of occupations form of the totally blind 
 gainfully employed with the corresponding propor- 
 tions for the partially blind, it will be seen that the 
 percentage of the former is higher in the professional, 
 trade and transportation, and manufacturing and 
 mechanical classes, while the partially blind have 
 a higher percentage in agricultural pursuits and do- 
 mestic and personal service. 
 
 The relation of occupation to bhndness is shown 
 in the following general tables : 
 
 Table 14 gives the number and per cent distribu- 
 tion, by class of occupations, of the blind over 10 years 
 of age gainfully employed, by age when blindness 
 occurred. 
 
 Table 15 gives the number of blind over 10 years 
 of age engaged in each specified occupation and class 
 of occupations, by color, sex, and age. 
 
 Table 16 gives the number of blind over 10 years 
 of age engaged in each specified occupation and class 
 of occupations, by age when bhndness occurred. 
 
 The Uind-deaf.—Oi the 64,763 persons reported 
 as blind, 2,772, or 42.8 per 1,000, were found to be 
 also deaf. 
 
 The returns for this class have been compiled accord- 
 ing to the age at which each disability occurred and 
 the results are given in Table 17, showing the age 
 at which blindness occurred in relation to the age 
 at which deafness occurred. 
 
 The coincidence of the two defects is not disclosed 
 by the figures showing age at occurrence by groups of 
 years, and can not be stated exactly except for those 
 blind and deaf from birth, of whom there are 76, but 
 it fell within the same age groups in 1,194 cases, as fol- 
 lows: At biuth, 76; between birth and 5 years of age, 
 64; at 5 to 9 years, 54; at 10 to 14 years, 37; at 15 
 to 19 years, 24; at 20 to 39 years, 145; at 40 to 59 
 years, 172; at 60 to 79 years, 429; and at 80 years 
 and over, 193. 
 
 There are 153 cases in which the unfortunate per- 
 sons lost both sight and hearing under 5 years of age.

 INTRODUCTION. 
 
 This report relates to the deaf of the United States 
 living on June 1, 1900. 
 
 In accordance with the census act the enumerators 
 of the Twelfth Census were required to return only 
 the name, sex, age, and post office address of each 
 deaf, or deaf and dumb person, leaving all further 
 details to be ascertained subsequently through corre- 
 spondence with the deaf persons themselves, or their 
 parents or guardians. 
 
 The nature of the instructions to the enumerators is 
 indicated by the extract given on page 3. 
 
 Upon receipt of the enumerators' special schedules 
 containing lists of persons reported to be deaf, or 
 deaf and dumb, a circular letter of inquiry, or indi- 
 vidual schedule, was sent to each address given, ask- 
 ing whether the person had been correctly returned as 
 deaf, or deaf and dumb, and requesting further 
 information in the form of replies to specific queries. 
 
 The special schools for the deaf in the United States 
 were also requested to furnish the Census Bureau with 
 the information contained in their school records 
 concerning deaf pupils admitted between June 1, 
 1890, and June 1, 1900. Similar information con- 
 cerning all pupils admitted from the opening of the 
 schools up to June 1, 1890, had been collected in 1890 
 upon cards which have been preserved. The same 
 form of card was used in 1900, and the complete card 
 catalogue, arranged alphabetically, was employed in 
 checking and verifying the returns made by the enu- 
 merators and by the deaf persons themselves in cases 
 where the persons had attended special schools. 
 
 The special schools for the deaf were also supplied, 
 upon request, with lists of deaf children of school age 
 within the territory covered by the schools, taken 
 from the enumerators' returns, and the superintendents 
 were requested to inform the Census Bureau of any 
 erroneous returns discovered. 
 
 The replies to the circular letter of inquiry, and the 
 correspondence with heads of schools for the deaf, 
 enabled the Census Bureau to eliminate from th'e enu- 
 merators' lists large numbers of persons who were 
 only hard of hearing, or who had been erroneously 
 returned as deaf, leaving a total of 89,287 persons 
 with seriously impaired powers of hearing. 
 
 Of these, 51,861 were not totally deaf, as they could 
 xinderstand loudly shouted conversation. The returns 
 
 in these cases have been tabulated separately under 
 the head of "partially deaf," although of course they 
 represent only a portion of the partially deaf of the 
 United States, every effort having been made to 
 exclude persons merely "hard of hearing" from the 
 returns. 
 
 Persons returned as both blind and deaf numbered 
 2,772. Since the returns in these cases are included 
 in the report on the blind because they were blind, they 
 are also included in the present report on the deaf 
 because they were deaf. 
 
 Comparing the total number in the two afflicted 
 classes, 71,795 persons were returned as blind and 
 89,287 as deaf; tut the aggregate number of blind and 
 deaf is less than the sum of these two figures, because 
 the blind-deaf cases are doubly reported. 
 
 Blind (alone) 69, 023 
 
 Deaf (alone) 86, 515

 The present report differs in several important 
 respects from former Census reports on the same 
 subject. 
 
 In order to secure as large aggregates as possible 
 upon which to base the statistical analysis, the tables 
 deal chiefly with the deaf of the whole of the United 
 States, rather than with those of the states and terri- 
 tories individually, or of the counties contained in them. 
 
 States and territories are the lowest units of geo- 
 graphic distribution employed; county tables are 
 omitted altogether, as they occupy space quite out of 
 proportion to their real importance or value, and the 
 figures are too small to yield statistical results of 
 significance. 
 
 Another difference relates to institution statistics: 
 No special inquiry has been made through the Census 
 Office concerning the deaf persons in institutions or 
 schools for the deaf, as such inquiry appeared to be 
 unnecessary in view of the fact that statistics of this 
 character are collected no less than three times every 
 year through other agencies. Such statistics are 
 compiled by: 
 
 1. The United States Government, through its Bu- 
 reau of Education (published annually in the report 
 of the United States Commissioner of Education). 
 
 2. The Conference of Superintendents and Principals 
 of American Schools for the Deaf (published annually 
 
 (65)

 THE DEAF. 
 
 in the "American Annals of the Deaf," Kendall Green, 
 Washington, D. C). 
 
 3. The American Association to Promote the Teach- 
 ing of Speech to the Deaf (published annually in the 
 "Association Review," Mt. Airy, Philadelphia, Pa.). 
 
 The published results contained in these three 
 sources of information are utilized in this report. 
 
 The assigned causes of deafness are classified by 
 their effect on the ear All the assigned causes act 
 only indirectly, the true cause of deafness being in 
 every case the injury to the ear and not the cause 
 assigned. 
 
 The present classification has been effected through 
 the cooperation of a committee of experts — Dr. Z. T. 
 Sowers, general physician. Dr. Charles W. Richardson, 
 aurist, and the late Dr. Swan ]\I. Burnett, oculist, all 
 of Washington, District of Columbia. 
 
 Diseases that produce the same effect upon the ear 
 are grouped together. For example, scarlet fever, 
 measles, disease of ear, etc., operate to produce an 
 abscess in the middle ear. They are therefore grouped 
 together, and the deafness is assigned to a "suppurative 
 condition of the middle ear." 
 
 The assigned causes of deafness are also considered 
 in connection with hereditary influences shown by the 
 consanguinity of the parents or the possession of deaf 
 relatives. Deaf relatives are classified into four 
 groups : a, deaf brothers, sisters, or ancestors (relatives 
 in the direct line) ; 6, collateral relatives (uncles, aunts, 
 cousins, and other relatives not a, c, or d); c, deaf 
 children (sons or daughters) ; and d, deaf husbands or 
 wives. 
 
 The present report also differs from former reports in 
 its treatment of occupations. In order that the occu- 
 pations of the deaf may be compared with the occupa- 
 tions of normal persons, the same classification has 
 been adopted as that employed in the Twelfth Census 
 for the general population of the country. 
 
 The occupations of the deaf are also considered in 
 connection with sex, race, and education, so that the 
 occupations of the whites can be compared with those 
 of the colored, and the occupations of the educated 
 deaf contrasted with those of the uneducated. In re- 
 lation to the educated deaf, the kind of school attended 
 is noted, so that the occupations of those who have 
 been educated in special schools for the deaf may be 
 compared with the occupations of those who have been 
 educated in the ordinary public schools of the country, 
 or who have not been educated at all. 
 
 Another difference relates to the classification of the 
 deaf themselves. 
 
 In the earlier Census reports the attempt was made 
 to enumerate the "deaf and dumb" alone, excludine 
 all of the deaf who could speak. In the Tenth Census 
 all persons who lost hearing before they reached the 
 age of 16 years were classed as "deaf and dumb," 
 whether they could speak or not ; and in the Eleventh 
 
 Census the deaf were divided into two broad classes 
 based upon their ability to speak, viz, "the deaf and 
 dumb" and "the deaf but not dumb." 
 
 In the present report the age or period. of life when 
 deafness occurred is adopted as the basis of classifica- 
 tion; and the deaf are divided into two broad classes 
 quite independently of their ability to speak — "the 
 deaf from childhood" and "the deaf from adult life." 
 
 The ability to speak is an acquired condition, and 
 not, therefore, suitable as a basis for classification. 
 Speech is usually acquired through hearing and imita- 
 tion, but it may also be acquired (independently of 
 hearing) through special instruction; and, as a matter 
 of fact, many deaf mutes are now taught to speak in a 
 more or less intelligible manner. These cases make 
 their appearance in the census returns as "deaf but 
 not dumb," thus apparently reducing the numbers of 
 the class "deaf and dumb," to which they originally 
 belonged. 
 
 It is very desirable that the classification of the deaf 
 should be based upon a natural condition which can 
 not be changed. The age or period of life when deaf- 
 ness occurred is a condition of this kind, and the deaf 
 and dumb, whether they have been taught to speak 
 or not, belong naturally to the class "deaf from child- 
 hood," and are thus differentiated from that large class 
 of speaking persons who lost hearing in adult life. 
 
 Another noteworthy difference between this and 
 former reports consists in the copious use 6f graphical 
 diagrams upon a small scale, illustrating the tables. 
 The smallness of the scale employed reduces to insig- 
 nificance minor details, in which only small numbers 
 are involved, thus bringing out clearly in relief the 
 really salient features of the tables. The diagrams 
 give a sort of bird's-eye view of the general features of 
 the tables, and when closer inspection is desired the 
 tables themselves give the details. 
 
 All the information tabulated by the Census Bureau 
 concerning the deaf will be found fully elaborated in 
 the general tables. All other tables used in this report 
 have been compiled from these. Tables 1 to 10 of the 
 general tables are summary tables, giving a survey of 
 the whole scope of the investigation. 
 
 COMPARISON WITH FORMER CENSUSES. 
 
 In taking the earlier censuses (1830 to 1870) the 
 enumerators were instructed to return only those who 
 were actually deaf and dumb; but in 1880 it was 
 recognized that many of the so-called deaf and dumb 
 could speak— imperfectly perhaps, but still sufficiently 
 to enable them to escape enumeration as persons 
 totally deprived of the power of utterance. It was 
 thus seen that the plan of limiting the returns to those 
 who were unable to articulate failed to secure a full 
 census of the class intended to be enumerated; and 
 in taking the census of 1880 the plan was adopted of

 considering all persons who lost hearing in childhood 
 as belonging naturally to the class " deaf and dumb," 
 whether, as a matter of fact, they were able to speak 
 or not. 
 
 This same plan has been adopted in the present 
 census, but it has been deemed advisable to extend the 
 age limits assigned to "childhood" from 15 years 
 (1880) to 19 years (1900), for the reason that special 
 schools for the deaf and dumb are open to all deaf 
 children of school age. All persons, therefore, who 
 lost hearing before the age of 20 are admissible as 
 pupils, and this quite irrespectively of their ability to 
 speak. It has also been deemed advisable in the 
 present report to designate this class as ' ' the deaf from 
 childhood (under 20)," rather than the "deaf and 
 dumb;" for it is manifestly incorrect to label as "deaf 
 and dumb" a class of persons containing many mem- 
 bers who can speak. For this reason the "deaf and 
 dumb" of 1880 would more properly be termed "the 
 deaf from childhood (under 16)." 
 
 The inclusion of speaking persons in the returns of 
 the deaf and dumb for 1880 is probably the main cause 
 of the increased ratio per million noted for that census 
 (Diagram 1). 
 
 There are other causes, however. Previously to 1880 
 the accuracy of the census returns depended upon the 
 enumerators alone, for there was no possibility of going 
 behind their returns and correcting errors; but in 1880 
 the Census Bureau entered into correspondence with 
 physicians residing in all parts of the country, through 
 whose agency the enumerators' returns were checked 
 and verified. Many names of deaf-mutes who had 
 been overlooked by the enumerators were supplied to 
 the Census Bureau by the physicians. 
 
 This correspondence revealed the fact, which has 
 been amply substantiated by the experience of the 
 present census, that the returns of the ordinary enu- 
 merators regarding the deaf, or deaf and dumb, are 
 erroneous in a large proportion of cases, and need cor- 
 rection and verification before being made the basis of 
 statistical inquiries. 
 
 In 1890 a new departure Vas made. Previously to 
 that year the census returns related to a portion only 
 of the deaf and not the whole, viz, the deaf and dumb 
 (1830 to 1870), or those who were supposed to belong 
 naturally to that class, even though they could speak 
 (1880); but in 1890, instead of relying upon the 
 enumerators to make the distinction desired, the 
 attempt was made to take a census of the whole num- 
 ber of the deaf, and to have the dividing line drawn by 
 experts in the Census Office during the examination of 
 the returns. 
 
 In 1890 the enumerators were instructed to make 
 returns of all persons who were so deaf as to be unable 
 to understand loudly shouted conversation, with the 
 object of limiting the inquiry substantially to persons 
 who were totally deaf. 
 
 The dividing line was drawn in accordance with the 
 
 practice of the earlier censuses and not with that of 
 1880. The deaf were divided into two broad classes, 
 viz, the "deaf and dumb" and the "deaf but not 
 dumb." Deaf-mutes who had been taught to speak in 
 oral schools were included among the "deaf but not 
 dumb," but comparison was made with former cen- 
 suses on the basis of the "deaf and dumb" alone. 
 
 Under such circumstances we would naturally expect 
 to find a falling off in the ratio per million of population 
 returned as deaf and dumb proportional to the activity 
 displayed by the special schools in imparting speech to 
 their pupils; and by reference to Diagram 1 it will be 
 observed that there was a decrease in 1890 as compared 
 with 1880. 
 
 This falling off, however, is more apparent than real, 
 because the returns of the deaf and dumb for 1890 
 included only persons who were reported as unable to 
 speak; whereas those for 1880 included all persons who 
 lost hearing before reaching the age of 16 years, many 
 of whom possessed some power of speech. The true 
 comparison, therefore, should be made with the earlier 
 censuses, in which the returns were limited to those 
 who were de facto deaf and dumb. 
 
 In taking the Twelfth Census (1900) the plan of 1890 
 was adopted of taking a census of all of the deaf who 
 were unable to understand loudly shouted conversation ; 
 but in accordance with a special statute of Congress 
 the enumerators were required to report only the 
 name, age, sex, and post office address of deaf, or deaf 
 and dumb, persons discovered, leaving all other details 
 to be ascertained by correspondence with the deaf per- 
 sons themselves. 
 
 After all corrections had been made in the data 
 secured for the present report, it was found that of 
 those who had been correctly reported as deaf, the 
 majority were able to understand loudly shouted con- 
 versation, in spite of the specific instructions to the 
 enumerators that such persons were not to be returned. 
 Out of 89,287 deaf, 37,426 were totally deaf and 51,861 
 could hear loudly shouted conversation. These latter 
 cases were too numerous to be ignored in the tabula- 
 tion of the results, and the returns have therefore been 
 analyzed under the head of "partially deaf," although 
 of course the cases reported constitute only a small 
 fraction of the partially deaf of the country. 
 
 It must be difficult for enumerators, who are usually 
 strangers to the persons they return, to decide defi- 
 nitely whether a person is or is not totally deaf ; and we 
 must credit the enumerators of the present census with 
 the intention of fulfilling their instructions to the best 
 of their ability. It is therefore probable that the ma- 
 jority ol the partially deaf persons returned were labor- 
 ing under serious defects of hearing, and were not sim- 
 ply "hard of hearing." They are believed, asaclass,tQ 
 be persons so deaf that it required correspondence with 
 the persons themselves to ascertain the fact that they 
 were not totally deaf. 
 
 In the present census the proportion of the popula- 
 
68 
 
 THE DEAF. 
 
 tion reported as deaf and dumb (unable to speak at 
 all) is less than one-half of that returned in 1890 
 (64S to the ijiilhon in 1890, 321 to the million in 1900). 
 (Diagram ].) 
 
 In explanation it may be said that many thousands 
 of persons who belong naturally to the class "deaf and 
 dumb" are reported, or rather reported themselves, in 
 the present census as able to speak; so that it is 
 obvious that the increased activity in articulation 
 teaching in our schools for the deaf is responsible for a 
 considerable portion of this result. 
 
 It is doubtful, however, whether this explanation 
 alone is sufficient to account for the great difference 
 between the two censuses in this respect ; and it is pos- 
 sible that there may have been an overestimate of the 
 deaf and dumb in 1890 or an underestimate in the 
 present census, or perhaps both suppositions may be 
 correct. 
 
 The returns of the 1890 census were based upon the 
 reports of the enunjerators alone, without verification 
 by correspondence with the deaf persons, as in 1900, 
 or by correspondence with physicians, as in 1880. It 
 is therefore probable that erroneous returns, similar to 
 those discovered in 1880 and 1900 through correspond- 
 ence, exist uncorrected in the returns for 1890. 
 
 On the other hand, several thousands of circular let- 
 ters of inquiry, sent out to the addresses of persons 
 reported as deaf by the enumerators of the present cen- 
 sus, failed to bring any reply, in spite of repeated 
 requests for information. These cases were therefore 
 thrown out of the investigation as resting upon insuf- 
 ficient evidence. They may represent erroneous 
 returns ; but, on the other hand, it is possible that the 
 enumerators were correct, and that the deaf persons 
 reported belonged to illiterate families unable to 
 respond by mail. 
 
 Whatever may be the deficiencies of the present cen- 
 sus, the information actually compiled is authoritative 
 so far as it goes, because it is based upon statements 
 made by the deaf persons themselves, or by parents, 
 guardians, or friends intimately acquainted with the 
 condition of the deaf persons considered. 
 
 In addition to the "deaf and dumb" returned in 
 1890, 80,616 persons, or 1,287 per million of population, 
 were reported as "deaf but not dumb," so that the 
 whole number of deaf returned in the 1890 census was 
 121,178, or 1,935 per million of population; whereas, 
 in the present census, 89,287 deaf are reported in all, 
 constituting a ratio of 1,175 per million of population, 
 and the number able to speak (including those who 
 speak well and those who speak imperfectly) is 64,918, 
 or 854 per million. 
 
 Table i shows the number of deaf and dumb re- 
 turned at each census since 1830 and the ratio per 
 million of population, the figures for the present 
 census including only those of the deaf who are "un- 
 able to speak at all."

 It is obvious at once from inspection of the dia- 
 grams that the returns of the different censuses are 
 not fully comparable with one another. The earlier

 later (1880 to 1900).

 and the deaf from childhood of the present census 
 are more comparable with the deaf and dumb of 1880

 In 1890 the age or period of life when deafness 
 occurred was noted both in the case of the "deaf and 
 dumb" and the " deaf but not dumb," so that it is pos- 
 sible, by adding the two classes together, to institute 
 a comparison between the 1890 and 1900 censuses 
 upon this basis, as well as on the basis of ability to 
 speak. This is done in Table m.

 The deaf from childhood (under 20) constituted 844 
 to the million in 1890 and 662 to the milHon in 1900. 
 The deaf from adult life (20 and over) constituted 890 
 to the million in 1890 and 473 to the milhon in 1900. 
 The period of life when deafness occurred (whether 
 childhood or adult life) was unknown in 12,623 cases, 
 or 201 to the million, in 1890, and unknown in 3,067 
 cases, or 40 to the million, in 1900. 
 
 The discrepancy between the two censuses is not. 
 
 therefore, confined to the deaf and dumb alone, 
 but is manifest on all the points of comparison noted. 
 It is therefore probable that in one or both censuses 
 the returns themselves are defective — probably exces- 
 sive in 1890 and deficient in 1900. 
 
 DISCUSSION OF THE EESULTS. 
 
 Age or period of life lolien deafness occurred. — The 
 period of life when deafness occurred (whether child- 
 hood or adult life) was unknown in 10.4 per cent of 
 the cases reported in 1890, but in only 3.4 per cent of 
 the cases returned in 1900. It may be well, therefore, 
 to emphasize the method by which this diminution 
 in the proportion of unknown cases was effected in 
 1900. 
 
 In the circular letters of inquiry sent out by the 
 Census Bureau the deaf persons were requested to 
 state as accurately as possible the exact age when 
 deafness occurred, and if this was unknown, to point 
 out the period of life when it occurred (whether 
 childhood or adult life). The returns showed that 
 in 7,697 cases the exact age when deafness occurred 
 was unknown or indefinitely stated: In 659 cases the 
 persons were less than 20 years of age at the time the 
 census was taken, and therefore lost hearing in child- 
 hood (under 20) ; in 404 cases the persons were reported 
 to have become deaf in "infancy," in 1,227 cases in 
 "childhood," and in 57 cases in "youth," making a 
 total of 2,347 cases deaf from childhood (under 20); 
 while in 1,224 cases the persons became deaf in "adult 
 life," and in 1,059 cases in 'old age," making a total 
 of 2,283 cases deaf from adult life (20 and over), 
 leaving a balance of 3,067 cases undetermined. 
 
 As the period of life when deafness occurred is 
 adopted as the basis of classification in the present 
 census, it is advisable to determine as accurately as 
 possible the number of deaf from childhood (under 20) 
 and from adult life (20 and over). There are 50,296 
 cases known to be deaf from childhood (under 20), 
 and 35,924 cases deaf from adult life (20 and over); 
 but it is estimated that the actual number deaf from 
 childhood (under 20) is 51,871, and deaf from adult life 
 (20 and over) 37,416. 
 
 In case the present classification is adopted in sub- 
 sequent censuses, it may be well to point out the 
 method by which this estimate has been made. 
 
 In 3,067 cases the period of life when deafness oc- 
 curred is unknown. In these unknown cases, however, 
 the numbers totally deaf and partially deaf were 
 known, and also the numbers who could speak well, 
 imperfectly, or not at all. 
 
 Table iv shows the percentage of the deaf who be- 
 came deaf at known periods of age, by certain specified 
 classes, and the application of the same in estimating 
 the number of the unknown period who became deaf 
 at the stated ages.

 The percentages given in Table iv afford us means of 
 estimating, in various ways, how many of these 3,067 
 cases were deaf from childhood, and how many were 
 deaf from adult life. For example, taking all the cases 
 in which the period of life when deafness occurred 
 was known, 58.3 per cent were deaf from childhood 
 and 41.7 per cent from adult life. Therefore, if these 
 percentages hold good for the unknown cases, 58.3 
 per cent of the 3,067 cases were deaf from childhood 
 and 41.7 per cent from adult life. This first estimate 
 gives us 1,788 deaf from childhood and 1,279 deaf 
 from adult life. 
 
 Again, the percentages in Table iv show that 90.5 per 
 cent of the totally deaf were deaf from childhood. Of 
 the 3,067 unknown cases, 795 were totally deaf, and 
 90.5 per cent of this number gives us 719 cases as 
 totally deaf from childhood, etc. The percentages in 
 Table iv enable us to make four distinct estimates of 
 this character, and the mean of the four estimates 
 yields the following results : 
 
 Out of a total of 3,067 cases in which the period 
 of life when deafness occurred was unknown, 1,575 
 were probably deaf from childhood (under 20), and 
 1,492 from adult life. Adding these to the totals 
 known to be deaf from childhood and adult life, we 
 obtain the results shown in Table v. 
 
 One of the main objects of comparing one census 
 with another is to determine, from an inspection of 
 returns compiled at different times, whether the pro- 
 portion of the population deaf, or deaf and dumb. 
 
 is increasing or diminishing. Unfortunately the ex- 
 isting censuses are not sufficiently comparable with 
 one another to enable us to do this, since no uniform 
 plan was adopted in the collection of the statistics. 
 Some light, however, may be thrown upon the sub- 
 ject from the returns of a single census by comparing 
 the present ages of the deaf with the ages of the whole 
 population. If deafness is increasing, we should nat- 
 urally expect to find a larger proportion of deaf among 
 the younger persons than among the older.

 The difficulty in making such a comparison lies 
 in, the fact that deafness occurs at different ages, so 
 that it would not be possible to include the whole of 
 the deaf in one determination. It so happens that 
 the great mass of the deaf and dumb lost hearing 
 before the age of 5, so that in their case we have a 
 considerable aggregate with comparatively slight dif- 
 ferences in the age when deafness occurred; and in 
 the deaf from birth, we have a large subgroup in 
 which no differences at all exist in this respect. 
 
 Table vi shows the present ages of the whole pop- 
 ulation of the United States in 1900 by five-year 
 periods, and the present ages of the totally deaf from 
 early childhood (under 5) — all of whom are, naturally, 
 deaf and dumb — distinguishing the congenital from the 
 noncongenital cases. The table also shows the propor- 
 tion deaf per million of population of the same age. 
 
 The ratios contained in Table vi are shown graphic- 
 ally in Diagrams 3, 4, and 5. 
 
 In these three diagrams the dotted lines represent 
 returns that are known to be incomplete. It is always 
 found to be the case that deaf children under 10 
 years of age are incompletely returned, and the 
 younger the deaf children the less complete are the 
 returns. 
 
 It is obvious from inspection of Table vi that the 
 proportion of the population totally deaf from early 
 childhood (under 5) is greater among the younger 
 persons than among the older (Diagram 3). 
 
 Eeferring to Diagram 4, there seems to be no sub- 
 stantial difference among the older persons in the 
 ratio per miUion totally deaf from birth, but among 
 the younger the ratio per million is very much greater. 
 For example, the totally deaf from birth constitute 
 
AGE WHEN DEAFNESS OCCURRED. 
 
 71 
 
 135 to the million among persons 30 to 35 years of 
 age, and 282 to the million among persons 10 to 15 
 years of age — a ratio more than double the former. 
 This result is probably due to the prevalence of inter- 
 marriages among the deaf and dumb during the latter 
 part of the nineteenth century. Some of these unions 
 have been productive of deaf offspring, who belong 
 largely to the class of totally deaf from birth. The 
 deaf, both of whose parents were deaf and dumb, are 
 mostly young, few of them having reached middle hfe.

 Referring to Diagram 5, relating to the noncon- 
 genital cases among the totally deaf from early child- 
 hood, the curve is more irregular than in the case of 
 those deaf from birth, as would naturally be expected 
 when we consider these persons became deaf from 
 apparently adventitious causes, some of which are 
 of an epidemical nature, like cerebro-spinal menin- 
 gitis. Upon the whole, the proportion <deaf is greater 
 among the younger persons than the older, and pro- 
 portionally greater as the age is younger. It is not 
 clear that we can interpret the figures to mean that 
 the proportion of the population noncongenitally deaf 
 (under 5) is increasing more rapidly than the popu- 
 15152—06 6 
 
 lation; for a curve of similar character to that in 
 Diagram 5 would be produced upon the assumption 
 that the death rate is greater in these cases than in 
 the population at large, which is not unlikely to be 
 the case when we consider the fact that these persons 
 lost hearing fTom severe illnesses which must have 
 tried their constitutions.

 Age when deafness occurred for the whole of the deaf. — 
 The age when deafness occurred is definitely stated 
 in 81,590 cases, and of these, 59 per cent became deaf 
 before reaching the age of 20 years, 48 per cent became 
 deaf before reaching the age of 10 years, 40 per cent 
 became deaf before reaching the age of 5 years, and 
 18 per cent were born deaf. One-half of the deaf lost 
 hearing before they were 11 years old.

 The large number returned as deaf from birth and 
 the small number reported deaf during the first and 
 second years of life after birth (Diagram 7), is sugges- 
 tive of some inaccuracy in the returns ; and this is ex- 
 tremely probable, for the reason that in many if not in 
 most cases the fact that an infant is deaf is not discov- 
 ered, or is not certainly known, until after he "is 2 years 
 of age. At or about the age of 2 most children begin 
 to speak, but the deaf child does not. This speechless 
 condition attracts attention and he is then found to be 
 also deaf. If during his infancy he has had some seti- 
 ous illness, the deafness is naturally attributed to that; 
 if not, the natural assumption is that he was born deaf. 
 It is probable that some of those reported deaf from 
 birth really lost hearing in infancy after birth, and that 
 some of those reported deaf from infancy after birth 
 were really born deaf. The irregularity of the figures 
 suggests that, on. the whole, too many are returned as 
 deaf from birth and too few as deaf during the first and 
 second years of life after birth. 
 
 The deaf from childhood of the census of 1900 conk- 
 pared with the deaf and dumb of former censuses, hy 
 states and territories. — In Tables 8 and 9 the deaf from 
 childhood of the census of 1900 are compared with the 
 deaf and dumb of former censuses, by states and terri- 
 tories. 
 
 The New Epgland states, and especially Connecti- 
 cut, show a larger proportion of deaf than the average 
 for the United States as a whole. From 1830 to 1860 
 Kentucky showed a relatively large ratio of deaf and 
 dumb as compared with the ratios of surrounding 
 states. In 1870 Indiana, Kentucky, and North Caro-

 lina became conspicuous in this respect. In 1880 the 
 predominance of Indiana over its neighboring states 
 became very marked, and this predominance has con- 
 tinued up to the latest census (1900). 
 
 From 1830 to 1860 the largest ratios appeared in 
 Connecticut, and since 1860, in the District of Colum- 
 bia. In both cases, however, the ratios are fallacious, 
 because of the existence in these parts of the country of 
 schools for the deaf which draw pupils from the whole 
 of the United States, whereas the ratios are based upon 
 the local population alone. During the first half of the 
 nineteenth century the American School for the Deaf 
 in Hartford, Conn, (then known as the American Asj- 
 lum for Deaf -Mutes), drew pupils from the whole of 
 the United States ; but as special schools for the deaf 
 multiplied the supply of pupils from the more distant 
 states was practically cut off and the school attendance 
 became more local in character. Even to-day, how- 
 ever, the school is by no means representative of Con- 
 necticut alone, for it draws pupils from all of the New 
 England states, a portion only coming from Connecti- 
 cut. The predominance of the District of Columbia 
 since 1860 is due to the existence within the District of 
 the Columbian Institution for the Deaf and Dumb, 
 with its primary and collegiate departments, known as 
 the Kendall School, and Gallaudet College (formerly 
 the National Deaf -Mute College). Both primary and 
 collegiate departments draw pupils from outside the 
 District of Columbia. Gallaudet College particularly, 
 being the only special school in the country for the 
 higher education of the deaf, attracts deaf students 
 from all parts of the United States. 
 
 The tables show a large proportion of deaf in the 
 New England states, especially Maine, New Hamp- 
 shire, and Vermont. Scarlet fever, measles, and other 
 
 diseases causing inflammation and abscess in the mid- 
 dle ear are the predominating causes, especially m 
 Vermont and New Hampshire, and congenital deaf- 
 ness is frequent in Maine. Nonsuppurative or ca- 
 tarrhal affections of the middle ear are also frequent in 
 these states, but catarrh, colds, etc., cause deafness 
 chiefly in adults rather than in children, and do not 
 appear as prominent causes of deafness among the deaf 
 from childhood or deaf and dumb. In their case scar- 
 let fever seems to be the principal cause. 
 
 The cause of the local congestion of the deaf in Ken- 
 tucky from 1830 to 1860, and its extension in 1870 to 
 North Carolina and Indiana, is unknown ; but the In- 
 diana congestion of 1880 appears to have been due 
 chiefly to an epidemic of cerebro-spinal meningitis. 
 This seems to be the same disease formerly known as 
 spotted fever, and it is not improbable that brain fever 
 is another name for it. The persistence of the Indiana 
 congestion up to the present census year, 1900, appears 
 to be due, in part at least, to the same cause. 
 
 Geographic distrihution of the deaf. — Tables vii, viir, 
 and IX relate to the geographic distribution of the 
 deaf, by states and territories. 
 
 Table vii shows the deaf, by age or period of life 
 when deafness occurred, for states and territories. 
 
 Table viii shows the deaf by degree of deafness, 
 also the deaf from childhood and the totally deaf from 
 early childhood, distinguished as deaf from birth and 
 as deaf subsequent to birth, for states and territories. 
 
 Table ix shows the deaf, by race, nativity (of whites) , 
 present age, and ability to speak, for states and terri- 
 tories. 
 
 Table x gives the ratios per million of total popu- 
 lation for the classes of deaf shown in Tables vii, viii, 
 and IX.

 THE DEAF. 
 
 Table x is illustrated by Maps 1,2, and 3, showing 
 the ratios per million of population in each state and 
 territory

 territories.

 (TTTTl 526 10 1052

 Map 2. — Number of totally deaf per million of population, by states and 
 
 territories. 
 
 Map 3. — Number of partially deaf per million of population, by states 
 and territories. 
 
 Map 1 shows the geographic distribution of the 
 total number of deaf reported at the Twelfth Census, 
 from which it appears that, upon the whole, deafness 
 
 is more common in the northern part of the United 
 States than in the southern. The North Atlantic 
 and North Central divisions show a larger ratio per 
 million than the South Atlantic and South Central 
 divisions, and the largest ratio of all is found in the 
 New England states. The ratios shown in the states 
 composing the Western division, with the exception 
 of California, are of comparatively slight significance, 
 because of the small numbers involved. 
 
 Maps 2 and 3 show, in contrast, the geographic 
 distribution of the totally deaf and the partially 
 deaf, and in studying these maps it will be remem- 
 bered that the totally deaf consist largely of persons 
 deaf from childhood and the partially deaf largely of 
 persons deaf from adult life. 
 
 Degree of deafness. — Out of an aggregate of 89,287 
 deaf, 37,426 were reported as totally deaf and 51,861, 
 as partially deaf (Table 1). • 
 
 Table 1 reveals the fact that the vast majority of the 
 totally deaf became deaf in childhood, before reaching 
 the age of 20 years, whereas the majority of the par- 
 tially deaf lost hearing in adult life (Diagram 8).

 Period of //fe when deafness occarred. 
 
 
 In Table xi the totally and partially deaf are ana- 
 lyzed by the age at which deafness occurred. 
 
 From this table it appears that out of 35,479 to- 
 tally deaf cases in which the age when deafness occurred 
 was definitely stated, 91 per cent were totally deaf 
 from childhood (under 20), 52 per cent were totally 
 deaf from infancy (under 2), and 36 per cent were 
 totally deaf from birth. More than half of the totally 
 deaf lost hearing before they were 2 years of age. 
 
 Of the partially deaf, about one-third became deaf 
 before they were 20, one-third between 20 and 40, and 
 one- third after reaching 40, approximately.

 - I^rtially deaf 
 
 Ahility to speak. — Out of an aggregate of 89,287 
 persons returned as deaf, 55,501 were able to speak 
 "well," 9,417 "imperfectly," and 24,369 "not at all" 
 (Table 1). 
 
 In the case of those who do not speak at all, the 
 period of life when deafness occurred (whether child- 
 hood or adult life) is known in 23,866 cases, and of these, 
 23,687, or more than 99 per cent, became deaf in child- 
 hood, before reaching the age of 20 years. 
 
 The class "deaf from childhood" thus includes sub- 
 stantially all of the deaf and dumb (Diagram 11). This 
 is true even if we include, as is usually done, "semi- 
 mutes," who speak imperfectly, as well as "deaf- 
 mutes" proper, who do not speak at all, among the 
 deaf and dumb; for nearly 98 per cent of these two 
 subgroups combined (deaf-mutes and semimutes) 
 became deaf in childhood, before reaching the age of 20 
 years. 
 
 On the other hand, the majority of the deaf who 
 speak well became deaf in adult life.

 In Table xii the returns of the deaf who speak ' ' well,' ' 
 "imperfectly," or "not at all," are analyzed by period 
 of life when deafness occurred (whether childhood or 
 adult life) and by degree of deafness (whether total or 
 partial). 
 
 Out of 24,369 deaf and dumb who can not speak, 
 23,482, or more than 96 per cent, were reported as 
 totally deaf; and only 887, or less than 4 per cent, as 
 partially deaf. Table xii is illustrated by Diagram 12.

 Decree of deafness -fofa/ or partial. 
 
 
 The small proportion of partially deaf is somewhat 
 surprising, in view of the fact that it is a common prac- 
 tice in American schools for the deaf and dumb to 
 summon the pupils in from the playground by the 
 ringing of a bell. In 1888 experiments were made in 
 a number of schools to ascertain the percentage of 
 children who could hear this call, and out of 1,475 
 pupils tested, 304, or nearly 21 per cent, could hear the 
 ringing of the bell ' ; but in the Census tables less than 
 4 per cent of the deaf and dumb are reported as par- 
 tially deaf. 
 
 It may possibly be that in the case of the deaf and 
 dumb there has been an overestimate of the number 
 totally deaf, for the test of total deafness adopted, al- 
 though perfectly applicable to deaf persons who can 
 speak, is not- so well adapted to distinguish the totally 
 from the partially deaf among the deaf and dumb. In 
 the Census tables those persons are returned as totally 
 deaf who "can not be made to understand what people 
 say even when they shout;" but the deaf and dumb 
 have no knowledge of spoken language, and so could

 laudet and Alexander Graham BeU presented to the Royal Commission 
 of the United Kingdom on the Condition of the Blind, the Deaf and 
 Dumb, etc.; with accompanying papers, postscripts, and an index. 
 Edited by Joseph C. Gordon, professor of mathematics, etc., in the 
 National College for the Deaf, Washington, U. S. A., published by the 
 Volta Bureau, Washington, D. C, 1892." Part II, query 21395.

 America" in the same volume. 
 
 not "understand ".even if they heard. Few Ameri- 
 cans could be made to understand Chinese, even though 
 the spoken words were shouted into their ears, but it 
 does not necessarily follow that such persons are totally 
 deaf; and spoken English is as unintelligible to the 
 deaf and dumb as Chinese is to us. 
 
 On the other halnd, the small proportion of partially 
 deaf among the deaf and dumb is explicable without 
 the assumption that the returns of the totally deaf are 
 excessive. Articulation teaching has been pursued 
 for a good many years in American schools for the deaf, 
 and it is known that the partially deaf acquire speech 
 more readily by instruction than those who can not 
 hear at all, and this would result in comparatively few 
 of them being returned as deaf and dumb ; they would 
 appear instead among those who speak, either well or 
 imperfectly. This interpretation, upon the whole, 
 seems more probable than the other. 
 
 The number of cases in which the period of life when 
 deafness occurred is known (Table xii) forms the 
 basis upon which the following percentages have been 
 calculated: Thirty-four per cent of those who could 
 speak well, 93 per cent of those who could speak imper- 
 fectly, and 99 per cent of those who could speak not at 
 all became deaf in childhood, before reaching the age 
 of, 20. Sixty-six per cent of those who could speak 
 well, 7 per cent of those who could speak imperfectly, 
 and 1 per cent of those who could speak not at all lost 
 hearing in adult life. 
 
 The following percentages have been calculated on 
 the basis of the whole of the deaf who speak well, im- 
 perfectly, or not at all (Table xii) : Fourteen per cent 
 of those who could speak well, 63 per cent of those who 
 could speak imperfectly, and 96 per cent of those who 
 could speak not at all were reported as totally deaf. 
 Eighty-six per cent of those who could speak well, 37 
 per cent of those who could speak imperfectly, and 
 4 per cent of those who could speak not at all were 
 returned as partially deaf. 
 
 It will thus be seen that the ability to speak (whether 
 well, imperfectly, or not at all) is largely dependent 
 upon the period of life when deafness occurred (whether 
 childhood or adult life) and upon the degree of deaf- 
 ness (whether total or partial). A correlation exists 
 between these three elements. 
 
 In Table xiii the deaf who speak well, imperfectly, 
 or not at all are analyzed by the age when deafness 
 occurred, and the results are shown graphically in 
 Diagram 13. 
 
 Speaking broadly, about one-third of the deaf who 
 speak well lost hearing before they were 20 years old, 
 one-third between 20 and 40, and one- third after reach- 
 ing 40. 
 
 Of the deaf who speak imperfectly or not at all, most 
 lost hearing at a very early age — before they were 5 — 
 and practically all became deaf before they were 20.

 A more exact statement is contained in Tables xrv 
 and XV, illustrated by Diagrams 14, 15, and 16. 
 
 Table xiv shows the number and percentage of the 
 deaf who speak well, imperfectly, or not at all, who 
 lost hearing before reaching certain specified ages. 
 
 From Table xiv and Diagrams 14 and 15 it appears 
 that substantially all of the deaf and dumb became 
 deaf before they were 20, nearly all (98 per cent) be- 
 fore they were 10, and the vast majority (92 per cent) 
 before they were 5. More than two-thirds lost hear- 
 ing before they were 2, and nearly one-half were born 
 deaf. 
 
 In the case of the semimutes, also, the vast majority 
 (93 per cent) became deaf before they were 20, nearly 
 three-fourths lost hearing before they were 5, nearly 
 one-half before they were 2, and more than one-quarter 
 were born deaf.

 Table xv and Diagram 16 show that the proportion 
 of the deaf who are deaf and dumb becomes progress- 
 ively greater as the age when deafness occurred is 
 younger. 
 
 In Table xvi (the totally deaf) and in Table xvii 
 (the partially deaf) the returns are analyzed by the 
 age when deafness occurred, so that it may be seen 
 how far the degree of deafness (whether total or 
 partial) modifies the results disclosed by Table xiii 
 (Diagram 13).

 Comparing Tables xvi and xvii, it will be observed 
 that comparatively few of the totally deaf speak well 
 (Diagram 17), and comparatively few of the partially 
 deaf speak imperfectly or not at all (Diagram 18). 
 
 The deaf and dumb consist mainly of persons totally 
 deaf from early childhood, under 5 (Diagram 17).

 The deaf who speak well consist mainly of persons 
 who became partially deaf in adult life (Diagram 18). 
 
 The deaf who speak imperfectly form an interme-

 Correlated conditions. — While it is obvious that 
 inability to speak is associated with inability to hear, 
 where the deafness occurred in childhood, it is equally 
 true that deafness itself, irrespective of the age when 
 it occurred, is not necessarily associated with dumb- 
 ness, for the majority of the deaf can speak perfectly 
 well (Table xii), including several thousands of cases 
 of persons totally devoid of the sense of hearing. 
 
 Neither partial nor total deafness, then, necessarily 
 interferes with the power of speech, the controlling 
 factor being the age or period of life when the deafness 
 occurred. The earlier the age when the deafness 
 occurred the larger the proportion who are deaf and 
 dumb. The largest proportion of deaf and dumb is 
 found among those who are born deaf (Table xv). 
 
 TTie condition of speecJi naturally resulting from deaf- 
 ness contrasted with the actual condition revealed iy the 
 census returns. — Period of life when deafness occurred: 
 Birth. — A little consideration will show that all persons 
 who are born deaf are naturally also dumb. The 
 dumbness is a necessary consequence of the deafness, 
 and not a defect in itself. We were all born dumb ; and 
 no one naturally acquires a language he has never 
 heard. The deaf-born child, then, necessarily remains 
 dumb after the age when others talk, because he has 
 never heard the language the others have acquired. 
 
 It is not surprising, therefore, that a large propor- 
 tion of the deaf from birth should be deaf and dumb. 
 It is only remarkable that any at all should be able to 
 speak. This is the fact that requires explanation. 
 
 Table xv shows that less than 75 per cent of the 
 deaf from birth are deaf and dumb; 3,669, or more 
 
 than 25 per cent, are reported as able to speak (Table 
 
 XIIl). 
 
 We can not attribute this result to inaccuracy on the 
 part of the enumerators of the Twelfth Census, for 
 the information did not come from the enumerators, 
 but from the deaf persons themselves in answer to a 
 circular letter of inquiry. 
 
 It may be possible that some of the deaf from birth 
 who were only partially deaf possessed a sufficient 
 amount of hearing to enable them to pick up imper- 
 fect speech for themselves by imitation in the natural 
 way, although every effort was made by the Census 
 Bureau to exclude from the returns persons who were 
 only hard of hearing. It is absolutely certain, how- 
 ever, that all those who were totally deaf from birth 
 were deaf and dumb at some period of their lives ; and 
 yet no less than 2,081 are reported as able to speak. 
 From Table xvi it appears that of these, 492 could 
 speak well and 1,589 imperfectly. 
 
 These are by no means all of the deaf and dumb who 
 appear in the returns of the Twelfth Census as speak- 
 ing persons, as will be evident from the following con- 
 siderations : 
 
 Speech is normally acquired through the sense of 
 hearing by a gradual process of imitation extending 
 through a series of years. If, then, deafness occurs 
 before or during the formative period of speech, the 
 natural result is that the person either remains dumb 
 or tends to revert to the speechless condition ; but once 
 the formative period has been passed and the speech 
 habit fully established, deafness no longer tends to 
 produce dumbness or to materially affect the charac- 
 ter of the articulation. 
 
 After hirth, under 2. — Normal children do not begin 
 to speak until they are about 2 years old. If a child 
 becomes deaf before reaching that age, he fails to ac- 
 quire speech just as though he had been born deaf. 
 All persons who lost hearing before they were 2 years 
 of age are naturally deaf and dumb. 
 
 Table xiii shows that 2,557 persons who became 
 deaf after birth and under the age of 2 are returned as 
 able to speak; 1,353 of these were totallj' deaf (Table 
 xvi) and 1,204 partially deaf (Table xvii). 
 
 2 and under 5. — If a child loses his hearing after 
 having commenced to talk and before reaching the age 
 of 5, his speech at best is imperfect; and though he 
 continues to speak for some time after he becomes 
 deaf, he soon forgets how to talk. The memory of a 
 little child is very short. No longer able to correct 
 his pronunciation by hearing the speech of others, his 
 articulation becomes more and more imperfect, until 
 finally he becomes a deaf-mute. All persons who lost 
 hearing after they had begun to talk and before reach- 
 ing the age of 5 naturally belong to the class "deaf 
 and dumb." They were not originally deaf-mutes, 
 but they have become so as time passed. 
 
84 
 
 THE DEAF. 
 
 Four thousand eight hundred and ninety-seven per- 
 sons who became deaf after 2 years of age and before 
 reaching the age of 5 are reported as able to speak 
 (Table xiii) ; 2,069 of these were totally deaf (Table 
 xvi) and 2,828. partially deaf (Table xvii). 
 
 5 and under 10. — Children who become deaf after 
 5 and under 10 years of age continue speaking in a 
 more or less imperfect manner for a long time after they 
 become deaf, but in process of time their speech becomes 
 more and more imperfect; many become dumb, but 
 most of them retain an imperfect articulation. 
 
 From Table xiii it appears that the majority of 
 persons — 4,324 out of 7,018 — who became deaf be- 
 tween 5 and 10 years of age are returned as speaking 
 well (totally deaf, 1,373; partially deaf, 2,951) instead 
 of speaking imperfectly or not at all, which is the natu- 
 ral condition resulting from their deafness. 
 
 10 and under 20. — At or about the age of 10 most 
 children have acquired the ability to read and write, 
 and, as a rule, if a child becomes deaf after reach- 
 ing the age of 10, he is able to read, although unable 
 to hear what others say to him. He speaks perfectly, 
 and the tendency to revert to the speechless condition 
 is much less marked than in the case of those who 
 become deaf at an earlier age. Inability to hear the 
 speech of others naturally leads him to seek the society 
 of books. Reading keeps up the knowledge of lan- 
 guage he possessed before he became deaf, and also in- 
 troduces to his notice multitudes of words that he does 
 not know how to pronounce. Not being able to hear 
 how they are pronounced by others, he naturally at- 
 tempts to speak them as they are spelled; but, unfor- 
 tunately, our written language is very unphonetical in 
 its character, and the new words acquired through 
 reading are pronounced in a very imperfect manner. 
 Thus, in the case of persons who lost hearing after the 
 age of 10 and under the age of 20, their speech, though 
 perfect at first, becomes peculiar in process of time, 
 and most of this class, especially the ilhterate, gradu- 
 ally become " seinimutes. " 
 
 A smaller proportion, the minority, become abso- 
 lutely deaf and dumb. This statement reflects the 
 natural condition resulting from deafness occurring 
 at this period of life. 
 
 From Table xiii it appears that 7,771 of those who 
 became deaf after 10 and under 20 were able to speak 
 well, only 507 imperfectly, and 247 not at all. 
 
 Adult life {20 and over). — There is no apparent rea- 
 son why the speech of those who become deaf in adult 
 life should be materially affected by their deafness, and 
 although the total number reported as unable to speak 
 is small (only 179, Table xiii) it is somewhat surprising 
 to find that any of them are returned as deaf and dumb. 
 We can only conclude that the dumbness in these cases 
 did not result from deafness, but from other causes not 
 specified in the returns. 
 
 Genei-al conclusions. — Deaf ness interferes rather with 
 the acquisition of speech than with its retention after it 
 has once been acquired, and the speaking habit fully 
 established by usage. 
 
 Deafness occurring in adult life, therefore, does not 
 materially affect the ability to speak; but deafness 
 occurring in childhood does. This is well established 
 by the returns of the present census; but it is obvious 
 that in the case of those who became deaf in childhood 
 the condition of the speech, as revealed by the census 
 returns, departs very materially from the natural con- 
 dition resulting from the deafness. Several thousands 
 of persons are reported as able to speak, who would 
 naturalh^ — without special instruction in the use of 
 their vocal organs — be deaf and dumb. 
 
 This result indicates either that the census returns 
 are grossly erroneous regarding the ability of the deaf 
 to speak, or that a great and beneficial work has been 
 accomplished by our special schools for the deaf in 
 imparting artificially, by instruction, the power of 
 articulate speech to large numbers of the deaf and 
 dumb. , 
 
 The first hypothesis can not be entertained, for what- 
 ever errors there may be in the present census, they 
 consist of omissions rather than of inaccuracies in the 
 tabulated material. The information actuallj^ compiled 
 is authoritative so far as it goes, because it came directly 
 from the deaf persons themselves in answer to a letter 
 of inquiry, or from parents, guardians, or friends inti- 
 mately acquainted with the condition of the deaf per- 
 sons considered, and is thus independent of any errors 
 on the part of the original enumerators. The latter 
 hypothesis is more probable and demands special 
 consideration. 
 
 No less than 11,123 persons who became deaf before 
 reaching the age of 5 are reported as able to speak 
 (totally deaf, 5,508; partially deaf, 5,620). All of these, 
 naturally, are deaf and dumb, excepting those of the 
 partially deaf, who may be only slightly deaf, but even 
 these belong to the class " semimutes," who are usually 
 included in the returns of the deaf and dumb. The 
 totally deaf cases certainly — all of them — belong natu- 
 rally to the class deaf and dumb. 
 
 Totally deaf from early childhood {under 5) . — Twen ty - 
 six thousand one hundred and fifty-two persons are 
 reported as totally deaf from early childhood (under 5). 
 Of these, 5,503 are reported as able to speak (1,353 
 speak well and 4,150 imperfectly) Table xvi. 
 
 The obvious interpretation of the figures is that these 
 persons have acquired speech artificially by special 
 instruction. 
 
 This conclusion is strengthened by the fact that the 
 vast majority of the totally deaf from early childhood, 
 as shown in Table xviii, have attended special schools 
 for the deaf where facilities exist for articulation 
 teachinsr.

 Out of 20,259 cases where the kind of school at- 
 tended is stated, 19,195, or 94.7 per cent, were edu- 
 cated in special schools (including 71 persons who 
 attended both special and other schools). These con- 
 stitute nearly three-fourths of the total, or 73.4 per cent 
 of 26,152 cases totally deaf from early childhood 
 (under 5). 
 
 The conclusion that we are here dealing with cases 
 of artificial acquisition of speech is still further 
 strengthened and, indeed, rendered certain hj an ex- 
 amination of the present ages of the above cases (Table 
 xix). 
 
 It is only within comparatively recent years that 
 articulation teaching on a wholesale scale has been car- 
 ried on in the United States; so that the majority of 
 the deaf who have acquired speech artificially by in- 
 struction in school are comparatively young, few of 
 them having passed middle life. 
 
 If, then, our conclusion is correct, we should natu- 
 rally expect to find, upon examining the ages of the 
 above cases, that the vast majority of the older per- 
 sons who have passed middle life, and the vast majority 
 of the younger persons who are under the school age, 
 are deaf and dumb ; whereas the proportion of deaf and 
 dumb among those of intermediate age should be less — 
 and progressively less, as the age is younger — down to 
 some minimum well within the limits, of school life, 
 and this we find to be the case. 
 
 Table xix shows the present ages of those who are 
 totally deaf from early childhood, by five-year periods, 
 and the number and percentage in each age group who 
 can speak well, imperfectly, or not at all. 
 
 The results presented in Table xix are shown 
 graphically by Diagram 19.

 Beginning with the older persons referred to in 
 Diagram 19, we find that the proportion deaf and 
 dumb approximates 90 per cent, the curve hovering 
 pretty steadily in the neighborhood of the 90 per cent 
 level down to the age group 40 to 45. From this 
 point the curve descends. The proportion deaf and 
 dumb becomes less (or in other words the proportion 
 able to speak increases) down to the age group 10 to 
 15, consisting mainly of children yet in school, of 
 whom only 65 per cent are deaf and dumb. Below 
 
86 
 
 THE DEAF. 
 
 tliis age group the curve again rises, because many 
 of the children under 10 years of age have not 
 yet entered school and are therefore in their natural 
 speechless condition. 
 
 Very few deaf children under 5 years of age have 
 been brought tinder instruction, so that here the pro- 
 portion deaf and dumb goes up to the normal 90 per 
 cent level and beyond. It is only remarkable that 
 it does not reach 100 per cent. 
 
 That these young children are not all deaf and 
 dumb is doubtless due to the fact that some have 
 only recently lost their hearing, and so have not had 
 time to forget their natural speech; while others may 
 have received speech instruction in a kindergarten 
 way in schools receiving pupils under the usual school 
 age. Infant schools for the deaf have recently made 
 their appearance, receiving pupils as young as 3 or 
 even 2 years of age, under the belief that deaf children 
 can most readily acquire speech at the natural age 
 when hearing children learn to talk. 
 
 The majority of those noted in Table xix as able to 
 speak, speak imperfectly; and this is consistent with 
 the conclusion that they have been taught to articulate. 
 
 The artificial speech acquired by the deaf is rarely 
 perfect. It is usually peculiar, like the pronuncia- 
 tion of a foreigner, and it has marked characteristics 
 of its own. It is probable, therefore, that most of the 
 deaf who have acquired speech by instruction are 
 returned as speaking "imperfectly" rather than 
 "well," excepting, perhaps, in the case of the par- 
 tially deaf, many of whom, by instruction, acquire 
 perfect speech. 
 
 Table xix relates exclusively to the totally deaf 
 from early childhood (under 5), which group includes 
 the great mass of the deaf and dumb (84.7 per cent). 
 Those who lost hearing at a later period of life, or 
 who are only partially deaf, respond more readily to 
 articulation teaching, and it is probable that a larger 
 percentage of the deaf and dumb among them have 
 been converted by instruction into speaking persons. 
 
 Table xx gives the number and percentage of pupils 
 taught speech in American schools for the deaf from 
 1884 to 1904. 
 
 Of the deaf and dumb admitted to American schools 
 for the deaf, the proportion receiving instruction in 
 the use of their vocal organs increased from 27.2 per 
 cent in 1884 to 41.3 per cent in 1890 and 63 per cent 
 in 1900. 
 
 Since 1900, the year to which the census statistics 
 specially relate, the percentage has continued to in- 
 crease. The latest available statistics from the 
 Annals (those for 1904) show that more than two- 
 thirds of the whole, or 67.2 per cent, were then taught 
 speech. Still later statistics have been published by 
 the Association Review, Volume VII, page 282, 
 showing that in 1905 (March 31) 69.1 per cent were 
 taught speech.

 1 Compiled from the American Annals of the DeaJ. 
 
 ' Figures for 1892 and subsequent years refer to number of pupils present 
 upon a specified day (Nov. 15) . Before 1892 they indicate the number present 
 during the calendar year, including portions of two school years. 
 
 The above statistics afford a satisfactory explana- 
 tion of the fact that several thousands of persons 
 who naturally belong to the class deaf and dumb 
 appear in the returns of the Twelfth Census as speak- 
 ing persons. The power of speech has been acquired 
 in these cases by instruction in school. 
 
 AUlity to read the lips. — Out of a total of 89,287 
 persons reported at the Twelfth Census as deaf, 
 14,474 could read the hps, 13,986 could not, and in 
 60,827 cases the ability to read the lips was not stated. 
 
 The large number of "not stated" cases is remark- 
 able; but the reason becomes intelligible from an 
 examination of Table- xxi, in which the ability to 
 read the lips is considered in connection with the 
 period of life when deafness occurred, the degree of 
 deafness, and the ability to speak. 
 
 The question relating to lip-reading (or "speech- 
 reading," as it is more correctly termed) was very 
 poorly answered by the partially deaf, and the ma- 
 jority of the answers were in the negative. Too few- 
 replies were receized to warrant analysis, and the' 
 whole of the partially deaf were therefore tabulated as 
 not answering the question. This accounts for the 
 large number of "not stated" cases among the deaf

 the vast majority of those who speak well, or who be-

 Table xxi is illustrated by Diagram 20. 
 
 So far as the census returns show, the power of 
 speech-reading is confined to the totally deaf. This 
 does not arise from any natural incapacity on the part 
 
 of the partially deaf to acquire the art, but from arti- 
 ficial conditions which interfere with its acquisition. 
 
 A person who is only slightly deaf usually turns his 
 head away from the person with whom he converses, to 
 one side or the other, to favor his best ear, often placing 
 his hand to his ear to increase the volume of sound. 
 
 The turning away of the head, while it may not per- 
 haps entirely prevent the possibility of speech-read- 
 ing, is certainly not favorable to it, for the speech- 
 reader must look at the speaker, so as to observe the 
 movements of his mouth and the expression of his face. 
 
 Many slightly deaf persons, however, do keep their 
 eyes fixed upon the speaker's face, and in such cases 
 it is probable that what they hear is unconsciously 
 supplemented by something they see. They may 
 not call this speech-reading or know anything con- 
 sciously about the art, but they recognize the fact that 
 they do not seem to hear so well with their eyes closed. 
 Perhaps it might be more correct to say that they have 
 less difficulty in understanding speech when they are 
 watching the face of the speaker than when their eyes 
 are closed. This means that sight undoubtedly aids 
 them in comprehending what is said.

 In cases of graver disability, where the degree of 
 deafness is so great as to make it very difficult to carry 
 on conversation by ear, the speaker's mouth is usu- 
 ally applied directly to the deaf person's ear, thus 
 precluding entirely the possibility of speech-reading. 
 It is probable that the partially deaf of the present 
 census belong largely to this class. 
 
 Even when resort is had to artificial appliances to 
 aid the hearing, the conditions are not favorable to 
 speech-reading, for the mouth of the speaker is apt 
 to be concealed, in whole or in part, by the mouth- 
 piece of the hearing tube into which he speaks. 
 
 On the other hand, the totally deaf, though labor- 
 ing under a greater natural disability than the par- 
 tially deaf, are not hampered by these artificial hin- 
 drances to speech-reading. They do not turn their 
 15152—06 7 
 
 heads away from the speaker in order to hear better 
 with one ear, for they do not hear at all. For the 
 same reason words are never spoken into their ears. 
 Artificial appliances, too, to aid the hearing never im- 
 pede their view of the speaker's mouth, for they do 
 not use them. They are free to rivet their whole at- 
 tention upon the visible manifestations of utterance. 
 It is not surprising, therefore, that some of them should 
 have succeeded in acquiring a useful abihty to read 
 the lips, even without special instruction, by simple 
 observation and persistent efliort. It is only surpris- 
 ing that the partially deaf should not have been equally 
 successful. Better equipped by nature, they are less 
 efficient in this respect. Two senses used together, 
 one supplementing the deficiencies of the other, would 
 seem to be a better equipment for speech-reading than

 the one sense of sight alone; but the partially deaf as 
 a class do not read the lips. The special difficulties 
 in their way, however, are all artificial and not inher- 
 ent in the nature of the case, and could therefore be 
 removed. 
 
 Speech-reading is now taught in our special sphools 
 for the deaf, so that many of the deaf from childhood 
 have had the opportunity of acquiring the art by in- 
 struction. Most of those, however, who lost hearing 
 in adult life have not apparently yet learned of this 
 important means of ameliorating their condition. 
 They fly to hearing trumpets and speaking tubes for 
 relief, but rarely think of "lip-reading" in this con- 
 nection. Many of them have never even heard the 
 word, or have associated lip-reading with the "deaf and 
 dumb" rather than with themselves. 
 
 Failure to reply to the simple question whether the 
 person could or could not read the lips can only be 
 taken as an indication of ignorance as to what is meant 
 by the term "lip-reading." This involves the further 
 point that the persons who failed to reply were, as a 
 matter of fact, unable to read the lips, for if they could 
 do so they would have known the meaning of the ques- 
 tion, and no apparent reason exists why they should 
 not have answered it. It is hardly conceivable that 
 several thousands of persons should have failed to 
 answer "yes" or "no" to that particular question, 
 while freely answering others, if they understood it. 
 We conclude, therefore, that they did not under- 
 stand it and that they could not read the lips. The 
 answers should have been in the negative. 
 
 From Table xxi it appears that the total number of 
 persons reported as able to read the lips was 14,474, 
 all of whom were totally deaf. These constitute 39 
 per cent of the totally deaf and 16 per cent of the whole 
 of the deaf. 
 
 Of these 14,474 cases, 12,755, or 88 per cent, were 
 deaf from childhood, and 1,516, or 10 per cent, were 
 deaf from adult life; 5,140, or 36 per cent, could speak 
 well; 4,693, or 32 per cent, could speak imperfectly; 
 and 4,641, or 32 per cent, could not speak at all. 
 Roughly speaking, about one-third could speak well, 
 one-third imperfectly, and one-third not at all. 
 
 It is rather remarkable that 4,641 persons who could 
 not speak at all should have been returned as able to 
 read the lips. The explanation seems to lie in the 
 fact that speech and speech-reading, though always 
 taught together in schools for the deaf, are two 
 separate and distinct arts, and pupils may succeed in 
 one and fail in the other. Many good speakers are 
 poor lip-readers and many good lip-readers are poor 
 speakers. The persons referred to probably acquired 
 their abihty to read the lips by special instruction in 
 school, in which case they were also taught speech; 
 and, since they were returned as unable to speak, this 
 means that they failed to profit by their speech instruc- 
 tion sufficiently to be included among those who speak 
 imperfectly or well, while retaraing a useful ability to 
 understand the speech of others by watching the mouth. 
 
 In Table xxii the deaf are analyzed by their ability 
 to read the lips, and by age when deafness occurred.

 Aj^e periods ivhen deafness occurred 
 
 
 From Table xxii it appears that very few of the deaf 
 who can read the lips lost hearing in adult life (Diagram 
 21), and that most of them (62 per cent) became deaf 
 in early childhood, before reaching the age of 5. 
 
 The deaf who can read the lips thus belong chiefly 
 to the class totally deaf from early childhood (under 
 5), all of whom are naturally deaf and dumb. 
 
 The strange anomaly is here presented, that those 
 who are by nature the least qualified to read the lips 
 (the deaf and dumb who are totally deaf) are most 
 successful in acquiring the art; whereas those who 
 are best qualified by nature (the partially deaf who 
 speak well) are least successful. 
 
 The explanation lies in the fact that most of the 
 partially deaf who speak well, became deaf in adult

 life and have not received any special instruction in 
 lip-reading; whereas most of the deaf and dumb who 
 are totally deaf, lost hearing in early childhood and 
 were sent to special schools for the deaf, where they 
 were taught speech-reading as a regular part of their 
 curriculum. The difference is due to instruction. 
 
 Usual means of communication. — Table 1 shows the 
 usual means of communication employed by the deaf. 
 Four methods of communication are noted: Si (sign- 
 language); fg (finger-spelling); sp (speech); and wr 
 (writing) . 
 
 Some of the deaf use one of these methods alone, 
 others employ two or more, and still others, all of 
 them. It therefore becomes advisable to classify the 
 methods of communication employed, in order to 
 study the combinations intelligently. 
 
 We may commence by dividing the deaf into two 
 classes, those who employ the sign-language and those 
 who do not. 
 
 Each of these classes may be divided into two broad 
 groups (analogous to genera), viz, those who emploj^ 
 finger-spelling and those who do not. 
 
 Each of these broad groups may be divided into two 
 subgroups (analogous to species), viz, those who em- 
 ploy speech and those who do not. 
 
 Each of these subgroups may be still further divided 
 into two varieties, those who resort to writing and 
 those who do not.

 Diagram 22 exhibits the whole scheme of classi-

 the varieties reported in the census returns, arranged 
 in accordance with the classification. Fifteen vari-

 combinations of si, fg, sp, and wr.

 The total number employing the sign-language is 
 25,748, the total using finger-spelling is 19,570, the 
 total using speech is 64,918, and the total who re- 
 sort to writing is 19,388. Writing, although the 
 clearest and most definite means of communicatfbn 
 known to the deaf, is as a rule used only as a last 
 resort, because it is, of all means known, the slow- 
 est and most laborious. We can not assume that 
 those persons can not write who do not specify writing 
 among the means they employ. This omission simply 
 means that they can make themselves sufficiently 
 understood by the other methods specified, and do riot 
 usually resort to writing as a means of communication. 
 
 Diagram 24 contrasts the usual means of communi- 
 cation employed by the deaf from childhood and deaf 
 from adult life; and by the totally deaf and partially 
 deaf, using "subgroups" as sufficiently detailed for 
 the purposes of comparison. 
 
 This diagram shows that the deaf from adult life 
 and the partially deaf employ substantially only one 
 
 of the methods of communication known, viz, sp 
 
 (speech without sign-language or finger-spelling).

MEANS OF COMMUNICATION. 
 
 91 
 
 Of the deaf from adult life, 99.5 per cent employ 
 sp, and only 0.5 per cent employ other means. 
 
 Of the partially deaf, 96.2 per cent employ sp, 
 
 and only 3.8 per cent employ other means. 
 
 The following percentages relate to the deaf from 
 childhood (under 20) and are based upon 47,880 cases 
 in which the usual means of communication are stated 
 (Table xxiii).

 Diagrams 25 and 26 contrast the usual means of com- 
 munication employed by the totally and partially deaf 
 from childhood (under 20), distinguishing the age when 
 deafness occurred by five-year groups. 
 
 From these diagrams it appears that comparatively 
 few of the deaf from childhood who lost hearing after 
 reaching the age of 5, whether totally or partially deaf, 
 
 employ other means of communication than sp 
 
 (speech without sign-language or finger-spelling) .

 Of those who became deaf before reaching the age 
 of 5, the partially deaf, with few exceptions, also em- 
 ploy sp (Diagram 26), so that the use of the 
 
 special means of communication (sign-language and 
 finger-spelling) seems to be confined chiefly to the 
 
 totally deaf who lost hearing before reaching the age 
 of 5 (Diagram 25). The number of persons employ- 
 ing sign-language or finger-spelling who do not belong 
 to this group (the totally deaf from early childhood) is 
 so small as to form only an insignificant fraction of the

 hearing between 5 and 10 years (Diagram 25) and the 
 partially deaf who became deaf before 5 (Diagram 26).

 (under 20), the usual means of communication, by

 Affe periods when deafness occurred. 
 
 
 From Table xxvi and the diagrams it will be ob- 
 served that the use of sign-language, finger-spelling, or 
 writing is substantially confined to persons who lost 
 hearing before they were 20 years of age; and that 
 comparatively few who became deaf after 5 years of 
 age employ them as means of communication. 
 
 The usual mgans of communication employed by 
 the deaf throw light upon their social environment, 
 for it is obvious that however much the deaf may 
 mingle with people generally in pursuing their daily 
 vocations in life, they are restricted in their social 
 intercourse to persons who understand the means of 
 
 communication they employ. It is with such per- 
 sons principally that they associate upon intimate 
 terms, and it is from among them that they choose 
 their partners in marriage. 
 
 In considering the four means of communication 
 employed by the deaf it will be noted that speech 
 and writing are understood by hearing people gen- 
 erally, and that sign-language and finger-spelling are 
 not. Speech and writing, therefore, are principally 
 employed by the deaf in communicating with hearing 
 persons; sign-language and finger-spelling principally 
 in talking with other deaf persons. 
 
 Although the majority of the deaf can speak, 
 speech is notxeadily understood by them on account 
 of their deafness. Only those who are partially deaf 
 or who can read the lips can understand it. Writing, 
 therefore, is the only means of communication under- 
 stood generally both by the deaf, and hearing, but its 
 use is limited to educated persons. While writing is 
 commonly employed in communicating with others 
 at a distance, it is comparatively rarely used in talking 
 with people close at hand. A deaf person may con- 
 verse by writing with a hearing person, or a hearing 
 person with a deaf; but the deaf do not communicate 
 with the deaf in this way, nor the hearing with the 
 hearing. Writing, therefore, as a direct means of 
 communication, is limited to the communications of 
 the deaf with the hearing and vice' versa.- 
 
 In communicating with hearing persons, speech 
 without writing (sp — ) is used by the deaf who speak 
 well, writing without speech (— wr) by those who do 
 not speak at all, and both speech and writing (sp wr) 
 by those who speak imperfectly — not necessarily both 
 at the same time, but speech in talking with persons 
 who can understand their imperfect articulation, and 
 writing with those who do not. Both speech and 
 writing (sp wr) may also be reported by persons who 
 speak well, in wMch case we may interpret the returns 
 to mean that these deaf persons were poor lip-readers, 
 
MEANS OF COMMUNICATION.

 and could not understand the speech of the persons 
 with whom they conversed, who were therefore 
 obliged to reply by writing. 
 
 Where speech is reported as the sole means of com- 
 munication ( — — sp — ) we may interpret this to 
 mean that the deaf persons can understand speech 
 as well as use it, so that other means of communica- 
 tion are not resorted to. Such persons, therefore, 
 are either partially deaf, or are persons who are able 
 to read the lips; and their social intercourse is with 
 hearing persons rather than deaf. 
 
 The sign-language is a special language peculiar to 
 the deaf. It is not understood by people generally, 
 and to the majority of the deaf themselves it is a 
 foreign language. If, as is probable, the deaf who 
 understand it are chiefly those who use it, then it is 
 obvious that more than two-thirds of the deaf (70.3 
 per cent) do not understand it, for only 29.7 per cent 
 employ it as a means of communication, and these 
 consist largely of persons who are totally deaf from 
 early childhood (under 5). 
 
 The sign-language, then, is employed chiefly by the 
 deaf in conversing with other deaf persons who lost 
 hearing completely in early childhood (under 5). It 
 is intelligible to only a small section of hearing persons, 
 who consist mainly of those, who, as children, were 
 thrown closely into association with the deaf who 
 employed it — chiefly the brothers, sisters, and chil- 
 dren of persons totally deaf from early childhood 
 (under 5). Few hearing adults acquire the language, 
 and these consist mainly of professional instructors of 
 the deaf. 
 
 Finger-spelling is employed incidentally by the 
 educated deaf who use the sign-language in talking 
 with one another, but chiefly as a means of expressing 
 proper names, like the names of persons and places. 
 Comparatively few of the deaf use it alone as a means 
 of communication except in talking with hearing 
 persons who understand it. The limitations to its 
 use are the same as those noted for the sign-language, 
 except that it is understood by a somewhat larger 
 circle of hearing persons. Hearing adults easily learn 
 to spell upon their fingers, whereas they find it as 
 difficult to acquire the sign-language as any foreign 
 tongue. 
 
 The American Manual Alphabet employed in 
 finger-spelling by the deaf is shown in the illustrations 
 on pages 96, 97, and 98, which have been copied from 
 plates supplied by the Volta Bureau, which were pre- 
 pared under the direction of the late Dr. Joseph C. 
 Gordon. 
 
 In concluding this subject we may say that when 
 the English language alone is employed in its spoken, 
 written, or finger-spelled forms without any recourse 
 to the sign-language ( — fg sp or wr) the deaf persons 
 associate principally, if not exclusively, with hearing 
 persons. 
 
 Where the sign-language (si — ) alone is 
 
 employed they associate principally, if not exclusively, 
 with persons totally deaf from early childhood (under 
 5) and their hearing brothers, sisters, or children. 
 
 Where both the sign-language (si) and the English 
 language (fg, sp, or wr) are employed, they associate 
 with both of the classes referred to above.

 deaf, 46,915 were males and 42,372 were females 
 (Table 2); the majority of the deaf are males. This 
 fact has often been commented upon ; for it is a matter 
 of common observation that in schools for the deaf, 
 male pupils are nearly always in the majority. The 
 question, therefore, has often been discussed: "Why 
 is it that there are more deaf males than females?" 
 Various hypotheses have been adduced, such as that 
 males are more exposed to the accidents and diseases 
 of life than females, etc. It may be well, however, 
 to be cautious about generalizations of this kind 
 without sufficient evidence, for the question proposed 
 bears a remarkable likeness to the old catch-question 
 that has puzzled so many school boys: "Why do 
 white sheep eat more than black sheep?" to which 
 the answer was, "There are more of them." There 
 are more males in the population at large than 
 females (Table xxvii), so that there is really nothing 
 
 surprising about the fact that the majority of the 
 deaf should be males. Of the total population, 51.1 
 per cent are males and 48.9 per cent, females. 
 
 In the case of the deaf 52.5 per cent are males and 
 47.5 per cent are females (Table xxviii). It thus 
 appears that the proportion of males among the deaf 
 is somewhat in excess of the proportion in the popu- 
 lation at large, so that there may be some truth after 
 all in the hypothesis that males are more exposed 
 to accidents of life than females, or more susceptible 
 to the diseases that produce deafness. It is to be 
 noticed, however, that the predominance of males is 
 not confined to those who lost hearing from accident 
 or disease, but extends to the congenitally deaf. Of 
 the deaf from birth, 53 per cent are males and only 
 47 per cent females (Table xxix). 
 
 Table xxvii shows the deaf by sex, race, and 
 nativity in relation to the time when deafness 
 occurred, degree of deafness, and ability to speak.

 stantial difference in the proportion of the sexes 
 among the deaf from childhood and the deaf from adult 
 life; but the proportion of males seems to be greater 
 among the totally deaf than the partially deaf, among 
 the colored than the white, and among Indians than 
 negroes. It is also greater among the foreign born 
 white than the native, and greater among those who 
 have no deaf relatives {a or h) than among those who 
 have. 
 
 In relation to acquired conditions it may also be noted 
 that the proportion of males is greater among those 
 who do not speak at all than among those who speak 
 imperfectly, and greater among those who speak 
 imperfectly than among those who speak well. The 
 proportion male is also greater among the married than 
 among the single, widowed, or divorced, and least of 
 all among the widowed. 
 
 From Table xxix it appears that there is an excep- 
 tionally large proportion of males (56.2 per cent) 
 among those who lost hearing in infancy (after birth, 
 under 2), and also among those who became deaf in 
 adult life between the ages of 60 and 80 (58.4 per 
 cent). 
 
 In regard to present age, the proportion of males 
 is larger among those under 20 years of age than over. 
 The proportion is also larger among those who have 
 attended school than those who have not, and' larger 
 among those who attended special than other schools. 
 
 From Table xxx it appears that the proportion of 
 males is exceptionally large among those who became 
 deaf from affections of the external ear (62.7 per cent) 
 and of the internal ear (58.5 per cent), but excep- 
 tionally small among those deaf from affections of the 
 middle ear/(46.7 per cent). 
 
RACE. 
 
 101 
 
 In relation to the principal assigned causes of deaf- 
 ness, the males are greatly in the preponderance^ among 
 those deaf from meningitis (59 per cbnt) and brain 
 fever (59.1 per cent). 
 
 Among the unclassified cases, those deaf from "mil- 
 itary service" and "falls and blows" naturally stand 
 out prominently as having an exceptionally large pro- 
 portion of males — 99.7 per cent in the former case and 
 
 63.2 per cent in the latter. 
 
 On examining the tables, it appears that males are 
 so generally in the preponderance that in cases where 
 females are in the majority we are at once struck by 
 the fact as something exceptional an5 apparently 
 abnormal. 
 
 From Table xxviii it appears that among the wid- 
 owed and divorced, females predominate (widowed, 
 
 64.3 per cent; divorced, 51.3 per cent); but females 
 also predominate to a still greater extent among the 
 widowed and divorced of the whole population of the 
 United States (widowed, 69.7 per cent; divorced, 57.5 
 per cent). The majority of the deaf having (a or h) 
 deaf relatives are females (50.4 per cent) and the pro- 
 portion female among those having no (a or h) deaf 
 relatives is exceptionally small (45.4 per cent). 
 
 From Table xxix it appears that the majority are 
 females among those who lost hearing between 10 and 
 15, 20 and 40, and in old age after 80 — males predom- 
 inating at other age periods when deafness occurred. 
 
 From Table xxx it appears that females predomi- 
 nate where deafness was caused by affections of the 
 middle ear, for example, scarlet fever, disease of ear, 
 measles, influenza, catarrh and colds ; whereas in all the 
 other cases noted males predominate, with the excep- 
 tion of those deaf from the indefinite cause "sickness '' 
 (52.4 per cent female) and cases noted as "hereditary" 
 (52.8 per cent female). 
 
 In examining the ability of the deaf to speak (Table 
 xxviii) it is perhaps noteworthy that, while females 
 are in the minority, the proportion of females is greatest 
 among those who speak well, least among those who 
 speak not at all, and intermediate among those 
 who speak imperfectly. It is a little difficult to inter- 
 pret this result, for the ability to speak is an acquired 
 and not a natural condition, and can not therefore be 
 directly correlated with sex. The opinion has often 
 been expressed by teachers of the deaf that females 
 acquire speech by instruction more readily than males ; 
 but the present figures relate to the whole of the deaf — 
 the deaf from adult life as well as the deaf from child- 
 liood — and not simply to those who have acquired 
 speech artificially in special schools; so that if there 
 is any truth in this explanation, we should conclude 
 that females, generally, acquire speech more readily 
 than males, whether naturally or by artificial means. 
 
 In comparing Tables xxix and xxx, it will be not§d 
 (1) that females predominate among those who became 
 
 deaf at three different stages of life, namely, 10 and 
 under 15, 20 and under 40, and after 80; and (2) that 
 females predominate among those who are deaf from 
 affections of the middle ear. It is therefore probable 
 that females are more susceptible to deafness from scar- 
 let fever, disease of ear, measles, influenza, catarrh, or 
 colds, at these three distinct periods of life, namely, 
 adolescence, practically all of the child-bearing period, 
 and old age. 
 
 While males predominate among- those .deaf from 
 meningitis and brain fever, and females among those 
 deaf from affections of the middle ear, we should be 
 cautious about basing definite conclusions upon these 
 facts alone. 
 
 This will be obvious from the following considera- 
 tions: The Indiana congestion (due largely to men- 
 ingitis and brain fever) and the New England conges- 
 tion (due largely to affections of the middle ear) show 
 that geographic conditions are involved. Now males 
 predominate in Indiana and females in the New Eng- 
 land states among the general population, and this 
 fact of itself would lead us to expect a preponderance 
 of males among the deaf of Indiana and a prepon- 
 derance of females among the deaf of the New 
 England st-ates, quite independently of any different 
 susceptibility among the sexes to the diseases specified 
 above. 
 
 In the present census (1900) Indiana is reported as 
 having a population of 1,285,404 males and 1,231,058 
 females, so that in that state 51.1 per cent are males 
 and 48.9 per cent are females. 
 
 In the case of the New England states. New Hamp- 
 shire and Massachusetts are the only states having a 
 larger female population than male, but if we include 
 Maine, Vermont, Connecticut, and Rhode Island, we 
 find a total male population of 2,763,796 and a total 
 female population of 2,828,221. In the New England 
 states, therefore, 49.4 per cent of the whole population 
 are male and 50.6 per cent are female. 
 
 Both in Indiana and the New England states the 
 sexes seem to be too nearly balanced to upset the hy- 
 pothesis of greater susceptibility of males to deafness 
 caused by meningitis and brain fever, and greater 
 susceptibility of females to deafness caused by affec- 
 tions of the middle ear. It is probable, therefore, that 
 the hypothesis is correct. 
 
 Race. — Out of 89,287 persons returned as deaf 84,361 
 belong to the white race and 4,926 to the colored 
 races (including 273 Indians and 4 Mongolians).

 • I Per cent not shown where base is less than 100. 
 
 From Table xxvii it appears that of the whole popu- 
 lation of the United States, 87.9 per cent belong to the 
 
RACE.. 
 
 103 
 
 white race and 12.1 per cent to the colored races (in- 
 cluding Indians and Mongolians). In the case of the 
 deaf (Table xxxi), 94.5 per cent are white and 5.5 per 
 cent colored, so that the proportion colored is less 
 anaong the deaf than among the general population. 
 
 Of the general population, 11.6 per cent belong to 
 the- negro race, 0.3 per cent to the Indian, and 0.2 per 
 cent to the Mongolian (including Chinese and Japa- 
 nese). Among the deaf (Table xxvii), 5.2 per cent 
 are of negro extraction, 0.3 per cent are Indians, but 
 the total number of Mongolians (only 4) is too small 
 to afford a basis for a percentage. 
 
 The comparatively small proportion of colored per- 
 sons among the deaf may indicate that colored persons 
 are less liable to deafness than white, or that the 
 returns of the colored are less complete than those of 
 the white population. Both hypotheses are probably 
 correct. 
 
 From Table xxxi it appears that the proportion 
 colored is larger among those deaf from childhood than 
 adult life. It is also larger among the totally than 
 among the partially deaf. The proportion colored is 
 substantially the same among males and females. In 
 relation to age when deafness occurred, it will be noted 
 that the proportion colored is twice as large among the 
 deaf from birth (11.6 per cent) as the average for the 
 whole of the deaf (5.5 per cent) ; but among those who 
 lost hearing after birth and under 2, the proportion is 
 abnormally small (3.1 per cent), and it may be possi- 
 ble that many of the colored were unable to decide 
 correctly whether deafness occurred at birth or in in- 
 fancy (after birth, under 2). The proportion colored 
 is larger among those who lost hearing before reaching 
 the age of 20 (7 per cent), and larger among those 
 who lost hearing in old age after 80 (7.7 per cent) 
 than in the intervening age periods. 
 
 In relation to present age the proportion colored is 
 larger among those who are under 20 years of age (9 
 per cent) than over 20 (4.5 per cent). 
 
 In relation to acquired conditions the proportion 
 colored is least among those who speak well, greatest 
 among those who speak not at all, and intermediate 
 among those who speak imperfectly. Among those 
 who attended school only 3.1 per cent were colored, 
 while among those who did not attend school 18.7 
 per cent were colored, from which it is obvious that 
 the education of the colored deaf is neglected to a 
 much greater degree than in the case of the white. 
 There is no difference in the proportion of the colored 
 among those who attended special or other schools. 
 
 From Table xxxii it appears that the proportion 
 colored is greater among those who became deaf from 
 affections of the external ear than among those who 
 lost hearing from affections of the middle ear, and inter- 
 mediate among those who lost hearing from affections 
 of the internal ear. It is still greater, however, among 
 the unclassified cases. 
 
 In considering the classified causes of deafness, the 
 15152—06 a 
 
 greatest proportion colored is found among those deaf 
 from malarial fever and quinine (12 per cent) ; whereas 
 catarrh and scarlet fever, which are known to be among 
 the principal causes of deafness in the country as a 
 whole, show the smallest percentages of colored (ca- 
 tarrh, 1.1 per cent colored; scarlet fever, 1.3 per cent). 
 
 In relation to the unclassified causes of deafness, the 
 largest percentages colored appear among the con- 
 genital cases (11.6 per cent) and among those deaf 
 from the indefinite cause "sickness" (11 per cent). 
 The proportion colored is also large among those deaf 
 from indefinite "fever" (8.2 per cent) and among those 
 deaf from falls and blows (8.8 per cent). 
 
 Table xxxiii shows the geographic distribution of 
 the white and colored races. The largest proportion 
 of colored appears, of course, in the Southern states, 
 and especially in those states composing the South 
 Atlantic division. 
 
 The statistics contained in Tables xxxi, xxxii, and 
 XXXIII are suggestive of a racial difference in suscep- 
 tibility to deafness. It appears at first sight that the 
 colored population is almost immune, so far as deaf- 
 ness is concerned, to diseases of the middle ear, which 
 are known to be predominant causes of deafness. 
 There are, however, many qualifying circumstances 
 that should be taken into consideration : 
 
 1 . In general, the largest ratios deaf from affections 
 of the middle ear are found in the New England states 
 and in those parts of the country bordering upon the 
 Great Lakes. It may be possible, therefore, that the 
 comparative freedom of the colored people from deaf- 
 ness caused by these diseases (catarrh, scarlet fever, 
 etc.) may be due to the fact that they do not reside in 
 localities favorable to the occurrence of the diseases 
 mentioned. It may be equally true that geographic 
 conditions account for the comparative prevalence of 
 malarial fever and quinine as a cause of deafness 
 among the colored. 
 
 2. Among those who lost hearing from affections 
 of the middle ear, the proportion colored may not be 
 as small as it appears from the returns; for the pro- 
 portion colored is comparatively large among those 
 deaf from indefinite causes, like sickness and fever. 
 These, if definitely specified, might prove to be d,is- 
 eases affecting the middle ear. It is probable that a 
 large proportion of the colored people could not dis- 
 criminate between these diseases as causes of deaf- 
 ness, on account of illiteracy and lack of medical at- 
 tention at the time deafness occurred. They might 
 even be unable to discriminate certainly between con- 
 genital and noncongenital deafness, for the same 
 reasons. 
 
 3. Several thousand letters of inquiry sent out to 
 deaf persons by the Census Office brought no reply; 
 these doubtless were letters principally addressed to 
 illiterates unable to respond by mail. The proportion 
 illiterate is known to be very much greater among the 
 colored than the white in the general population (col- 
 
104 
 
 THE DEAF. 
 
 ored, 44.5 per cent; white, 6.2 per cent). Illiteracy 
 is also more common among the colored deaf than the 
 white, as is shown by the small percentage colored who 
 have attended school, and the large proportion colored 
 who did not know their present ages (19.9 per cent). 
 
 In short, we can not rely upon the hypothesis that 
 there is a racial difference in the susceptibility to deaf- 
 ness. While the census returns seem to support this 
 hypothesis, the factors of uncertainty are so large as 
 to deprive the results of value, and it is probable that 
 the returns themselves are defective regarding the col- 
 ored races. 
 
 Nativity ofwiiites. — Out of a total of 89,287 persons 
 
 returned as deaf, 84,361 were white; and of these, 
 69,865 were native, 13,786 were foreign born, and in 
 710 cases the nativity was unknown (Table 2). 
 
 Table xxvii relates to the sex, race, and nativity 
 of the deaf, as compared with the whole population of 
 the United States; and Tables xxxiv, xxxv, and 
 XXXVI relate more particularly to nativity, and show 
 the proportion native and foreign born among the 
 white deaf, as follows : 
 
 Table xxxiv shows, for the white deaf, the number 
 and percentage of native and foreign born, by age 
 when deafness occurred, degree of deafness, ability to 
 speak, sex, and present age.

 The statistics of Table xxvii iadicate that out of 
 the total white population of the United States, 84.7 
 per cent were native and 15.3 per cent foreign born. 
 
 Table xxxiv shows that of the white deaf, 82.8 per 
 cent were native and 16.4 per cent foreign born, so 
 that it appears that the proportion foreign born 
 among the white deaf is slightly in excess of the 
 proportion foreign born in the total white population. 
 
 In the case of the white deaf, the proportion foreign 
 bom is greater among those deaf from adult life than 
 among those deaf from childhood. It is also greater 
 among the partially than the totally deaf, and slightly 
 greater among males than females. In regard to age 
 when deafness occurred, the proportion foreign born 
 is greatest among those who lost hearing between 60 
 and 80 years of age and after, least among those who 
 became deaf before 20, and intermediate in the inter- 
 vening age periods when deafness occurred. 
 
 In regard to present age, the proportion foreign 
 born is greater among those over 20 years of age than 
 under. In relation to ability to speak, the proportion 
 foreign born is greatest among those who speak well. 
 
 least among those who speak not at all, and interme- 
 diate among those who speak imperfectly. 
 
 In regard to classified causes of deafness (Table 
 xxxv), the proportion foreign born is greatest among 
 those deaf from colds (33.9 per cent), and it is also 
 great among those deaf from typhoid fever (22 per 
 cent) and influenza (18.1 per cent), and least among 
 those deaf from meningitis. 
 
 In relation to unclassified causes of deafness, the 
 proportion foreign born is greatest among those deaf 
 from old age (34.4 per cent), and large among those 
 deaf from falls and blows, and from the indefinite 
 cause sickness. 
 
 Table xxxvi relates to the geographic distribution 
 of the white deaf, distinguishing the native from the 
 foreign born. The proportion foreign born is of 
 course greatest in those parts of the country which 
 have the largest foreign born population. 
 
 The majority of the foreign born deaf became deaf 
 in adult life, and it is therefore probable that in most 
 cases the deafness occurred after they reached /this 
 country. This also accounts for the fact of the small

 proportion of foreign born among the deaf from 
 meningitis and scarlet fever, for these are diseases 
 characteristic of childhood rather than adult life. 
 
 Tlie process of audition, and the mechanism whereby 
 it is effected. — Diagram 31 presents a sectional view of 
 the human ear, and Diagram 32 an enlarged plan of 
 the organ of hearing. 
 
 A source of sound may be considered as consisting 
 essentially of an oscillating body immersed in air. 
 
 Considering the to and fro movements which take 
 place toward or from the listener's ear, we may note 
 that each time the movement is toward the ear the air 
 particles in the immediate vicinity are struck a blow 
 in the direction of the ear, much as a billiard ball 
 might be struck by a cue. They shoot off under the 
 impulse in the direction of the ear, but can go only a 
 very little way before they are arrested by collision 
 with other air particles which take up the movement. 
 Much as an impulse may be transmitted through a 
 
 line of billiard balls by successive collisions of ball 
 with ball, so the aerial impulse is transmitted through 
 the free air by successive collisions of air particles 
 with air particles. When the impulse finally reaches 
 ^the listener's ear the air particles in the external ear 
 are crowded together by the shock and are thus 
 condensed in the passageway, or .meatus, causing 
 increased pressure upon the drum membrane of the 
 ear, pushing it in a little way (Diagrams 31 and 32). 
 
 When the motion of the oscillating body is from 
 the ear an opposite effect is produced, resulting in 
 rarefaction of the air in the external ear, causing a 
 lessening of pressure upon the drum membrane. 
 
 A source of sound thus operates to produce alternate 
 condensations and rarefactions of the air in the 
 external ear, causing vibratory movements of the 
 tympanic membrane. The membrane moves inward 
 when the air pressure is increased and outward when it 
 is diminished. 
 
 Diagram 31. 
 
 Diagram 32. 
 
 
 
 
 The middle ear contains a mechanism for trans- 
 mitting the vibrations of the membrane to the liquid 
 contained in the internal ear (Diagram 32). This 
 consists of a series of small bones, or ossicles, of which 
 the malleus, or hammerhead, is attached directly to 
 the tympanic membrane. The stapes, or stirrup- 
 shaped bone, at the other end of the series acts some- 
 what like a piston. Its flat end is attached to a mem- 
 brane covering the oval opening into the labyrinth. 
 The transmitting mechanism of the middle ear thus 
 consists essentially of a piston operated by a stretched 
 membrane. When the tympanic membrane moves 
 inward, the stapes, or piston, is also pushed inward, 
 thus exerting increased pressure on the liquid in the 
 labyrinth. When the tympanic membrane moves 
 outward the pressure on the liquid is relaxed. 
 
 The liquid contained in the internal ear is thus 
 subjected to changes of statical pressure; but in 
 the coiled-up portion of the labyrinth known as the 
 cochlea, or snail shell, there is also a to and fro move- 
 
 ment of the fluid itself, resulting from the elasticity 
 of the membrane covering the second opening into 
 the labyrinth (the round window). The passageway 
 of the cochlea is divided longitudinally into two 
 distinct channels communicating only at the tip — 
 shaded differently in the drawing (Diagram 32) . When, 
 therefore, the stapes, or piston, is pushed in at the 
 oval window, an actual displacement of the fluid in the 
 cochlea takes place, traveling up one channel and down 
 the other and bulging out the membrane of the round 
 window. The to and fro movement of the liquid in the 
 cochlea causes a corresponding movement of the hairs, 
 or rods, that line the passageways, and which are 
 connected with the terminals of the auditory nerve. 
 
 There can be little question that the true organ of 
 hearing is located within this coiled-up portion of the 
 labyrinth (Diagram 32), but its exact nature and 
 mode of operation are obscure. 
 
 The organ of Corti, which is found here, bears a 
 curious resemblance to a musical instrument contain- 
 
108 
 
 THE DEAF. 
 
 ing multitudes of rods of different lengths, which are 
 supposed to be tuned to respond to different pitches 
 of sound — a sort of harp in miniature within the ear. 
 The single vibration which alone is transmitted to 
 the internal ear — the resultant of all the sonorous^ 
 vibrations that exist in the air outside of the ear — is 
 supposed to be here analyzed into its constituent 
 musical elements by the sympathetic vibration of 
 those rods of Corti which correspond to them in pitch. 
 The organ of Corti, however, may not be so essential 
 to hearing as is commonly supposed, for it seems to be 
 totally wanting in parrots and other birds that imitate, 
 and therefore perceive, the sounds of human speech. 
 
 At the other end of the labyrinth from the cochlea, 
 the curious arrangement of the three semicircular 
 canals is worthy of note (Diagram 32) — an arrange- 
 ment in which the plane of each canal is substantially 
 at right angles to the planes of the other two, thus 
 reminding us of the three planes used by mathema- 
 ticians in coordinating directions in space. 
 
 The semicircular canals do not seem to be concerned 
 in the process of hearing, although it is obvious that 
 they constitute a sense organ of some kind, because 
 they are plentifully supplied with nerve filaments 
 connected with hairs, or rods, as in the case of the 
 cochlea. Under the influence of sound vibrations trans- 
 mitted to the liquid of the internal ear by the to and 
 fro movement of the stapes at the oval window, the 
 liqiiid in the semicircular canals is subjected to changes 
 of statical pressure, but without the to and fro dis- 
 placement of the fluid, as in the case of the cochlea. 
 If, however, the head should be moved in any direc- 
 tion, displacements would be produced by the inertia 
 of the fluid. These displacements would differ in the 
 three canals, according to the direction and extent of 
 the movement. It is probable that the semicircular 
 canals constitute a special sense organ, whereby we 
 perceive the direction and extent of bodily movements. 
 After waltzing continuously a sensation of dizziness is 
 usually experienced for some time after stopping, 
 which is probably due to the continued movements of 
 the liquid in one of the canals. Many totally deaf 
 persons fail to experience any sensation of dizziness 
 under such circumstances; and they experience a 
 difficulty in walking steadily in the dark. It is prob- 
 able that in such cases the injury to the ear has 
 extended to the semicircular canals, so that the persons 
 have lost the use of an organ intimately connected with 
 the instinctive balancing of the body while in motion. 
 
 The true organ of hearing seems to be hidden away 
 in the convolutions of the cochlea; but, as it is im- 
 mersed in a liquid, it is not directly accessible to sound 
 vibrations. The capacity for hearing may exist, and 
 yet the person may be deaf on account of some defect 
 in the transmitting apparatus. Perfection of hearing, 
 therefore, depends upon the proper functioning of the 
 tympanic membrane and the transmitting mechanism 
 of the middle ear. 
 
 The tympanic membrane must be suitably stretched 
 in order to be sensitive to delicate changes of air pres- 
 sure in the external ear. It differs from an ordinary 
 stretched membrane in not being flat. It is somewhat 
 conical in shape with the concavity outward, thus 
 resembling, to a certain extent, the under surface of an 
 open umbrella. It can be stretched to a greater or less 
 degree by movements of the malleus, to which it is 
 attached. A very slight movement inward of the end 
 of the malleus increases the tension; and the act of 
 listening consists in the adjustment of certain muscles 
 attached to the malleus, whereby the proper tension 
 of the membrane is secured. There is thus an accom- 
 modation of the ear to feeble sounds comparable to the 
 accommodation of the eye for near vision — an adjust- 
 ment of the focus, so to speak. 
 
 A stretched membrane is most sensitive to transitory 
 impulses when the normal pressure of the air is the 
 same on both sides of it. The pressure of the air 
 within the middle ear tends to push the tympanic 
 membrane outward, and the pressure of the air in the 
 external ear tends to push it inward. When these 
 opposite pressures just balance one another the mem- 
 brane is free to be acted upon by the transitory im- 
 pulses of sound without being impeded by an 
 unbalanced pressure from within or without. The 
 external pressure of the atmosphere is subject to 
 change; and without some means of introducing air 
 into the middle ear or removing air from it when 
 necessary, the tympanic membrane would constantly 
 be working at a mechanical disadvantage on account 
 of unbalanced pressures. The Eustachian tube affords 
 the means. Through its agency, a communication is 
 established between the middle ear and the back part 
 of the mouth (the pharynx) . During the act of swal- 
 lowing saliva the end of the Eustachian tube in the 
 pharynx is opened, thus permitting free communica- 
 tion between the external air and the cavity of the 
 middle ear, resulting in equilibrium of pressure on both 
 sides of the tympanic membrane. The Eustachian tube 
 also serves as a drainage tube for the middle ear, pre- 
 venting secretions from accumulating there. 
 
 Caiises of deafness. — In the Twelfth Census 89,287 
 persons were returned as deaf, and in 10,115 cases the 
 causes of deafness were unknown (Table 5). In the 
 remaining 79,172 cases the supposed causes were 
 specified. 
 
 In many cases, however, the assigned causes are 
 vague and unsatisfactory. For example, "military 
 service, 3,242 cases; sickness, 2,143; fever, 1,436; 
 medicine, 205; headache, 136; hard work, 101; 
 diarrhea and cholera infantum, 90 "; etc. 
 
 To these may be added the following as examples 
 of the curious and fanciful causes of deafness sometimes 
 assigned in individual cases: "Caused by milk of 
 diseased cow; chewing paper and speaking loud in 
 my ear; bitten by a rat; holding nose and mouth shut 
 and blowing until head would buzz; driving Govern- 
 
CAUSES OF DEAFNESS. 
 
 109 
 
 ment teams on the plains; eating caustic potash; 
 going with hay shockers; ran a piece of shingle down 
 throat; worms; worry"; etc. No less than 1,514 
 cases of this character were reported. (See footnotes 
 to Table xxxviii.) Such causes as these — even if they 
 are connected with the production of the deafness, 
 which is often doubtful — are very remote causes 
 indeed. 
 
 We may smile at the idea of driving Government 
 teams on the plains as a cause of deafness; but we 
 can readily trace a remote connection b-etween the 
 supposed cause and the effect. The driver speeding 
 the Government teams across the plains was exposed 
 to the weather and maj^ have taken cold, resulting in 
 catarrh of the middle ear, which may ultimately have 
 caused his deafness. 
 
 It seems more satisfactory to say that deafness was 
 caused by some specific disease — say scarlet fever, for 
 instance — than by driving Government teams, yet 
 really the one is no more a cause of deafness than the 
 other. Both act indirectly by producing effects that 
 become causes for other effects ; and they differ simply 
 in the degree of their remoteness from the ultimate 
 effect produced — deafness. It is a matter for serious 
 consideration that all the assigned causes of deafness, 
 even the most plausible, are of this same indirect 
 character, and are not in themselves true causes of 
 deafness at all. It will readily be recognized that 
 military service is not in itself a cause of deafness; 
 for out of the vast number of persons who have been 
 engaged in military service only a very small fraction 
 are deaf. All of the other causes, however, fall into 
 the same category; for out of the millions of people 
 who have had scarlet fever, for example, a very small 
 fraction indeed are deaf. Like driving Government 
 teams on the plains, the specific diseases usually 
 assigned may indirectly be causes of deafness, but are 
 not so of themselves alone. 
 
 The concussion of the air due to the discharge of 
 heavy artillery may rupture the membrane of the ear 
 of one near at hand, and the internal ear may be so 
 affected by the shock as to have its usefulness impaired ; 
 but in this case the true cause of the deafness is the 
 injury to the ear, and not directly the concussion of the 
 air, far less the cannon that produced it, or the still 
 more remote cause — military service. 
 
 Military service may be the cause of a person 
 being present when a cannon is fired ; the firing of the 
 cannon may be the cause of a concussion of the air; 
 the concussion of the air may be the cause of an injury 
 to the person's ear; and the injury to the ear may be 
 a cause of deafness. After the manner of "The House 
 that Jack Built," the cause of deafness may be made 
 anything you choose, if you only carry back the chain 
 of causation far enough. Scarlet fever and other 
 diseases, usually accepted as legitimate causes of deaf- 
 ness, belong to this same class, for they only act in- 
 directly through intermediate agencies. Scarlet fever. 
 
 for example, differs from military service simply in the 
 fact that in the chain of causation it is nearer the 
 ultimate effect produced. 
 
 Scarlet fever may be the proximate cause of an 
 abscess in the middle ear; the suppurative process in 
 the middle ear may cause serious injury and even total 
 destruction of necessary parts of the delicate machinery 
 of the ear; and the injury to the ear may thus cause 
 deafness. There are many other diseases, however, 
 that produce a similar injury to the ear and in a similar 
 manner. For example, measles, influenza, diphthe- 
 ria, pneumonia, erysipelas, smallpox, tonsilitis, bron- 
 chitis, etc. In the present report, therefore, all these 
 diseases are grouped together and the deafness is at- 
 tributed to " a suppurative affection of the middle ear." 
 
 The principle has been adopted of classifying the 
 assigned causes by their effect upon the ear, grouping 
 together in one class all those diseases or proximate 
 causes that produce the same effect upon the ear. 
 Accordingly causes of deafness are divided into three 
 broad groups, as follows: Affections of the external 
 ear, affections of the middle ear, affections of the 
 internal ear. 
 
 Each group is divided into subgroups, as follows:

 Out of 89,287 deaf, the causes of deafness have been 
 classified in 47,967 cases, or a majority of the whole; 
 31,205 cases remain unclassified; and in 10,115 cases 
 the causes are unknown.

 tions of the middle ear are the predcninating causes. 
 Comparatively few lost hearing from affections of the 
 external ear. The percentage of cases in each class 
 is as follows: External ear, 1.8 per cent; middle ear, 
 72.6 per cent; internal ear, 25.6 per cent — total classi- 
 fied, 100 per cent. 
 
 Subgroups. — The principal subgroups seem to be 
 four in number; these, with the percentage of cases 
 included in each, are shown as follows: Middle ear — 
 
 suppurative affections, 36.5 per cent; nonsuppurative 
 (or catarrhal), 36 per cent. Internal ear — affections 
 of labyrinth, 5.7 per cent; affections of nerve, 19.5 
 per cent. Other subgroups, 2.3 per cent. Aggregate 
 classified, 100 per cent.

 From Table xxxviii and Diagram 33 it appears 
 that among the classified cases the principal assigned 
 causes are: 
 
 Scarlet lever 7, 424 
 
 Disease of ear 4, 210 
 
 Measles 2, 469 
 
 Influenza 1, 776 
 
 Catarrh 11.702

 Braio fever 2, 013 
 
 Typhoid fever %^^ ^ ^^ 
 
 Minor causes 7, 617 
 
 Aggregate classified 47, 967 
 
 Malarial fever is given as a cause of deafness in 
 some cases, and quinine in others. In large doses 
 quinine is known to affect the hearing; but it is 
 doubtful whether malarial fever, without quinine, 
 produces deafness. As it is probable that all of the 
 malarial fever cases were dosed with quinine, and that 
 most of the quinine cases had malarial fever or were 
 threatened with it, the best disposition of these 
 causes seems to be to group them together and at- 
 tribute the deafness to an affection of the internal ear, 
 for quinine is known to have a specific effect upon the 
 labyrinth. 
 
 Meningitis includes all persons returned as deaf 
 from cerebro-spinal meningitis, meningitis (simply), 
 or spotted fever. It is probable that brain fever is 
 the same thing under another name; but the number 
 of cases returned under this head seems to be suffi- 
 ciently large to justify the retention of brain fever 
 as a specific cause. 
 
 Catarrh and colds probably constitute one and the 
 same disease; but the number of cases of deafness 
 
 due to colds seems to be large enough to demand sepa- 
 rate recognition. 
 
 Among the assigned causes of deafness in the clas- 
 sified cases, the following are specially predominant: 
 Catarrh and colds, 14,776; scarlet fever, 7,424; men- 
 ingitis and brain fever, 6,004. These three causes 
 alone include the majority of the classified cases (58.8 
 per cent). 
 
 From Diagram 34 it appears that among the un- 
 classified cases the principal assigned causes are : 
 
 Congenital , ... 14, 472 
 
 Old age ^'^81 
 
 MiUtary service 3, 242 
 
 Falls and blows 2, 243 
 
 Sickness 2, 143 
 
 Fever 1'^^^ 
 
 Ho'-^'l^'^^y °^ 27,806 
 
 Minor causes 3.399 
 
 Aggregate unclassified 31, 205 
 
 First in importance and overshadowing all of the 
 others are the congenital cases-^14,472 in number. 
 These, with two others, tabulated under the head of 
 "other causes unclassified," constitute the "deaf 
 from birth" — 14,474 cases. 
 
 It is unfortunate, considering the large numbers 
 involved, that the assigned causes of deafness re- 
 ferred to in Diagram 34 are too vague to enable us to 
 decide definitely the location or nature of the defect 
 in the hearing apparatus. 
 
 Congenital deafness probably involves the internal- 
 ear, for the deaf from birth as a class are totally 
 deaf. Falls and blows also are apt to produce injury 
 to the internal ear. Those deaf from old age are, as 
 a class, only partially deaf, so that in their case the 
 internal ear is not incapacitated. It is probable that 
 the defect relates chiefly to the external ear, result- 
 ing from impacted cerumen or thickening of the drum 
 membrane. Military service may mean almost any- 
 thing. Deafness due to the discharge of artillery would 
 affect the internal ear; so would typhoid fever and 
 malarial fever accompanied by quinine. Other dis- 
 . eases incident to military service, like catarrh and 
 colds arising from exposure to the weather, might 
 involve the middle ear. Sickness, fever, and hered- 
 itary causes would probably not involve the external 
 ear, but might refer either to the middle ear or the 
 internal ear. 
 
 If all the causes of deafness could be classified by 
 their effect on the ear, it is probable that the propor- 
 tions deaf from affections of the external ear and of 
 the internal ear would be considerably increased, lead- 
 ing to a corresponding diminution in the proportion 
 deaf from affections of the middle ear. 
 
 In Tables xxxix and xl the classified causes of 
 deafness, and the principal assigned causes, are pre- 
 sented in connection with their geographic distribution. 
 
 Table xxxix shows,* by geographic divisions and 
 states and territories, the deaf from the classified 
 causes, grouped according to the effect of the causes 
 upon the ear.

 THE DEAF. 
 
 Table xli is illustrated by the series of shaded maps 
 constituting Maps 4 to 9, inclusive, showing the ratio 
 per million of population in each state and territory 
 reported as deaf from the specified causes. 
 
 In 47,967 cases the assigned causes of deafness have 
 been classified by their effect upon the ear, and Map 4 
 shows approximately the proportion of the popula- 
 tion in each state or territory who lost hearing from 
 the classified causes. 
 
 Map 4. — Numher of deaf from dassijled causes per million of population, 
 hy states and territories. 
 
 Four grades of shading are employed: The second 
 indicates a proportion double that shown by the first; 
 the third, three times that proportion ; and the fourth, 
 four times — at least approximately. The largest pro- 
 portion deaf from the classified causes, indicated by 
 the fourth or heaviest shading, is found in the terri- 
 tory covered by Maine, New Hampshire, and Ver- 
 mont. The territory covered by the third grade of 
 shading abuts upon this and extends westward as a 
 narrow tongue as far as Nebraska and Kansas — includ- 
 ing these states. The next, or second, shading extends 
 pretty uniformly over the rest of the country (exclud- 
 ing the Western division) , except in the states of North 
 Carolina, South Carolina, and Mississippi. The states 
 composing the Western division, with the exception of 
 California, have very small populations, so that the 
 ratios deaf have not the same significance as in the 
 case of the older and more thickljr settled states, since 
 the addition or subtraction of: a mere handful of deaf 
 would make an appreciable change in the ratios. 
 
 Broad groups. — It appears that the states having the 
 largest ratios deaf from affections of the middle ear 
 compose a territory covering the New England states 
 
 and the states bordering on the Great Lakes (New 
 York, Ohio, and Michigan), with an outlying territory 
 in Iowa. The largest ratios of all are found in Maine, 
 New Hampshire, and Vermont, and the smallest in the 
 Southern states. 
 
 The largest ratios deaf from affections of the internal 
 ear are found in a territory covering the North Central 
 division of ' the United States (except Minnesota, 
 North Dakota, South Dakota, and Nebraska), with 
 outlying extensions in New York, Maryland, Ken- 
 tucky, and Arkansas. The largest ratio of all is found 
 in Indiana, and the smallest, if Arizona be disregarded, 
 in South Carolina. 
 
 Subgroups. — Maps 5 and 6 show, in contrast, the 
 geographic distribution of the deaf who lost hearing 
 from suppurative and nonsuppurative (or catarrhal) 
 affections of the middle ear; and Maps 7 and 8 relate 
 to deafness caused by affections of the labyrinth and 
 auditory nerve. 
 
 Principal assigned causes. — Map 9 shows the geo- 
 graphic distribution of the congenital (unclassified) 
 deaf. 
 
 The larger ' ratios, congenitally deaf, prevail over 
 the greater portion of the country (excluding the 
 Western division) ; and the largest ratios are found in 
 a group of states comprising Kentucky, Tennessee, 
 Virginia, and North Carolina, with a detached area in 
 Maine. The largest ratio of all is found in North Caro- 
 lina. 
 
 Map 10 shows the average percentage of sunshine 
 in the states and territories during a period of 31 
 years (1870 to 1901), from records compiled by the 
 United States Weather Bureau under the direction of 
 Prof. Willis L. Moore. 
 
 It is noteworthy that the area of country having the 
 least percentage of sunshine corresponds very closely 
 to the area showing the largest ratios deaf from 
 affections of the middle ear. We would naturally 
 expect that a cold, damp climate would favor the pro- 
 duction of catarrhal affections of the middle ear 
 (Map 6), but the sunshine map corresponds more 
 closely with the map showing the geographic distribu- 
 tion of affections of the suppurative variety (Map 5) 
 caused principally by scarlet fever. 
 
 Maps 11 and 12 relate to the geographic distribu- 
 tion of the totally deaf from early childhood (under 5) , 
 all of whom naturally are deaf and dumb, distinguish- 
 ing the congenital cases (Map 11) from the noncon- 
 genital (Map 12).

CAUSES OF DEAFNESS. 
 
 119 
 
 It win be seen from Table xlii that the number 
 deaf from childhood exceeds the number deaf from 
 adult life in each of the three broad groups — external 
 ear, middle ear, and internal ear. This predominance 
 is especially marked where deafness resulted from 
 affections of the iaternal ear. 
 
 The deaf from childhood predominate among those 
 
 deaf from suppurative affections of the middle ear and 
 affections of the auditory nerve, and the deaf from adult 
 life predominate in the case of nonsuppurative affec- 
 tions of the middle ear and affections of the labyrinth. 
 In Diagram 35 the principal assigned causes are 
 considered in connection with the period of life when 
 deafness occurred.

 From Diagram 35 it is clearly seen that the pre- 
 dominant causes of deafness are different in the case 
 of deaf from childhood and the deaf from adult Hfe. 
 Scarlet fever, "meningitis, and brain fever, which are 
 among the leading causes of deafness occurring in 
 childhood, are comparatively insignificant as causes 
 of deafness occurring in adult life. On the other 
 hand, catarrh, colds, and influenza, which are the 
 leading causes of deafness occurring in adult life, are 
 of lesser importance as causes of deafness in child- 
 hood. Catarrh is reported as the cause (of deafness) 
 in over 35 per cent (35.1) of the assigned causes of 
 deafness occurring in adult life. Among the unclassi- 
 fied causes it is somewhat noteworthy that most of 
 the "hereditary" cases lost hearing in adult life, and 
 that none of them were born deaf. 
 
 The difference between the deaf from childhood and 
 
 the deaf from adult life may be illustrated by giving 
 in each case the principal assigned causes among the 
 classified cases, in the order of their importance, as 
 follows :

 Under 2. — The congenitally deaf form the mass 
 of those who lost hearing before the age of 2, and 
 among the noncongenital cases scarlet fever, dis- 
 ease of ear, measles, laeningitis, and brain fever 
 seem to predominate slightly over the other causes 
 assigned. 
 
 2 and under 5. — Scarlet fever and meningitis stand 
 out prominently as causes of deafness occurring at 
 this period. Disease of the ear and brain fever are 
 next in importance. It is interesting to note that 
 over 65 per cent of the cases due to brain fever occur 
 before the age of 5. 
 
CAUSES OF DEAFNESS. 
 
 121 
 
 5 and under ^0.— Where deafness occurred between 
 5 and 10 years of age, scarlet fever is markedly the 
 leading cavise, and meningitis only slightly predom- 
 inates over the other causes. 
 
 10 and under 15. — No single cause seems to be pre- 
 dominant in a marked degree. Scarlet fever and 
 catarrh are slightly conspicuous. Meningitis is less 
 conspicuous than in the preceding groups. 
 
 15 and under 20. — Catarrh now takes the lead, but 
 only slightly, and scarlet fever and meningitis no 
 longer appear as conspicuous causes. 
 
 20 and under Jfi. — Deafness occurring in adult life 
 between the ages of 20 and 40 seems to be due chiefly 
 to catarrh. A considerable number, however, report 
 deafness as caused by military service. Malarial fever 
 and quinine, and typhoid fever, which are also slightly 
 conspicuous, are more prominent at this period than 
 at any other. 
 
 ■ Jfi and under 60. — The only conspicuous cause is 
 catarrh, but it is less conspicuous than in the preced- 
 ing age period. 
 
 60 and under 80. — Deafness occurring between the 
 ages of 60 and 80 is chiefly recorded as due to old 
 age, although catarrh still shows conspicuously, but in 
 a much less marked degree than in the two preceding 
 age periods. 
 
 80 and over. — The only conspicuous cause assigned 
 for deafness occurring at this period is old age. Two- 
 thirds of the cases occurring after 80 years of age are 
 due to this cause. 
 
 In relation to the four principal assigned causes of 
 deafness it may be noted that congenital deafness 
 occurs exclusively at birth, and deafness due to catarrh 
 almost exclusively in adult life. Meningitis produces 
 deafness chiefly before the age of 5 and scarlet fever 
 before the age of 10. 
 
 Table xliii shows the percentage deaf from child- 
 hood and from adult life for each of the principal as- 
 signed causes. 
 
 From Table xliii it is seen that in affections of the 
 middle ear the proportion deaf from adult life more 
 nearly approaches the proportion deaf from childhood 
 than in either of the other two broad groups, although 
 the proportions in the several causes under affections 
 of the middle ear vary greatly. The proportion deaf 
 
 from childhood is largest in affections of the internal 
 ear, being over 70 per cent of the total number of such 
 cases. In only one of the leading causes under this 
 group does the proportion deaf from adult life exceed 
 that of the deaf from childhood, namely, in malarial 
 fever and quinine.

 More than 90 per cent of the deafness from scarlet 
 fever, meningitis, and brain fever, more than 75 per 
 cent of the deafness due to measles, and over 65 per 
 cent of the deafness due to disease of the ear occurred 
 in childhood; on the other hand, more than 60 per 
 cent of the deafness from influenza, catarrh, and colds 
 occurred in adult life. 
 
 Among the unclassified cases about 75 per cent of 
 the "hereditary" cases lost hearing in adult life. It 
 is noteworthy that over 70 per cent of the deafness due 
 to fever, over 65 per cent of the cases due to falls and 
 blows, and over 60 per cent of the cases due to sickness 
 occurred in childhood. It is interesting also to note 
 that 9 per cent of the deafness due to military service 
 occurred "in childhood (under 20 years).

 1 Symbols for deaf relatives — a, deaf brothers, sisters, or ancestors; 6, deaf uncles, aunts, cousins, or other relatives not a, c, or d; c, deaf children (sons or 
 daughters) ; d, deaf husbands or wives. 
 
 The results contained in Table xliv relating to 
 total and partial deafness are shown graphically in 
 Diagram 37 (page 1^3) . 
 
 Broad groups. — It appears that affections of the 
 middle ear result chiefly in partial deafness, and affec- 
 tions of the internal ear chiefly in total deafness. 
 
 Subgroups . — Suppurative affections of the middle 
 ear appear to be much more productive of total deaf- 
 ness than nonsuppurative, or catarrhal, affections. 
 Affections of the labyrinth result chiefly in partial 
 deafness and affections of the auditory nerve in total 
 deafness. 
 
 Principal assigned causes. — From Diagram 37 it 
 appears that of the diseases affecting the middle ear, 
 scarlet fever seems to be the only one producing total 
 deafness in a majority of the cases. Catarrh produces 
 
 chiefly partial deafness. Of the diseases affecting the 
 internal ear, meningitis and brain fever produce chiefly 
 total deafness. 
 
 In regard to the unclassified causes, the deafness is 
 chiefly total among the congenital cases and partial 
 among those deaf from old age, military service, or 
 hereditary causes. 
 
 More than 80 per cent of those deaf from influenza, 
 catarrh, or colds were only partially deaf, and more 
 than 80 per cent were totally deaf among those deaf 
 from meningitis, brain fever, and among the congenital 
 cases. More than 85 per cent were only partially deaf 
 among those deaf from old age, military service, or 
 hereditary causes. 
 
 In Table xlv the deaf are shown by causes of deaf- 
 ness, in relation to sex, race, and nativity of the whites.

 Period of life when deafness occurred. — Table xlvi 
 shows that the percentage deaf from suppurative affec- 
 tions of the middle ear is more than twice as great 
 among the deaf from childhood as among the deaf from 
 adult life, and the proportion deaf from affections of 
 the auditory nerve more than three times as great. 
 
 On the other hand, the proportion deaf from non- 
 suppurative or catarrhal affections of the middle ear is 
 more than three times as great among the deaf from 
 adult life as among those deaf from childhood. 
 
 Degreeof deafness. — The percentage congenitally deaf 
 is eleven times as great among the totally as among the 
 partially deaf, and the proportion deaf from affections 
 of the auditory nerve more than four times as great. 
 On the other hand, the percentage deaf from nonsup- 
 purative or catarrhal affections of the middle ear is 
 nearly four times as great among the partially as among 
 the totally deaf. 
 
 8ex. — The percentage deaf from affections of the 
 internal ear is gjeater among males than females, and 
 the proportion deaf from affections of the middle ear 
 greater among females than males. The proportion 
 born deaf and deaf from old age is about the same in 
 either case. Military service and falls and blows are 
 of course responsible for a greater proportion of cases 
 among the males than the females. 
 
 Race. — The percentage deaf from affections of the 
 middle ear is more than twice as great among the whites 
 as among the colored. In the case .of scarlet fever, 
 eight times as great. On the other hand, the propor- 
 tion deaf from malarial fever and quinine is four times 
 as great among the colored as among the whites; and 
 the proportion born deaf more than twice as great. 
 
 Nativity of whites.— The percentage deaf from the 
 specified causes are larger among the native- whites 
 than the foreign born excepting in the case of colds,

 typhoid fever, old age, military service, falls and blows, 
 and sickness. An extremely small percentage of the 
 foreign born lost hearing from meningitis. 
 
 Colored races.— Tii& proportion born deaf and deaf 
 from affections of the internal ear is greater among 
 the negroes than among the Indians; and the pro- 
 portion deaf from affections of the middle ear, old 
 age, falls and blows, and indefinite "sickness" greater 
 among the Indians than the negroes. More than -i per 
 cent of the negroes lost hearing from malarial fever 
 and quinine, and less than 1 per cent of the Indians. 
 
 Deaf relatives. — The percentage boi-n deaf and deaf 
 from disease of ear, .catarrh, and from "hereditary" 
 causes is greater among those who have deaf relatives 
 than among those who have not; and the percentage 
 deaf from meningitis, brain fever, typhoid fever, old 
 age, military service, falls and blows, and sickness is 
 less. 
 
 Consanguinity of parents. — The most striking fea- 
 ture seems to be the large proportion congenitally 
 deaf among those whose parents were cousins. The 
 percentage congenitally deaf is nearly three times 
 as great among those whose parents were cousins as 
 
 among those whose parents were not; the percentage 
 deaf from disease of ear is also larger, but only 
 slightly. The percentage deaf from scarlet fever is 
 less, but not to any great extent; and the percentage 
 deaf from catarrh, though considerably less, is sufh- 
 ciently great to give catarrh prominence among the 
 assigned causes of deafness, both where the parents 
 were cousins and where they were not. 
 
 Meningitis, old age, and military service are not 
 at all prominent where the parents were cousins, but 
 moderately so where they were not. 
 
 Out of a total of 89,287 deaf, 4,065, 4.5 per cent of 
 the total or 5.1 per cent of those answering, reported 
 that their parents were cousins; 75,530, 84.6 per cent 
 of the total or 94.9 per cent of those answering, re- 
 ported that their parents were not cousins; and in 
 9,692 cases, or 10.9 per cent of the whole, the question 
 was not answered. Therefore at least 4.5 per cent of 
 the deaf are the offspring of cousin-marriages.

 THE DEAF. 
 
 In the case of the deaf from birth the proportion 
 whose parents were cousins is more than twice as great 
 as when all the deaf are considered, 11.8 per cent of 
 the deaf from birth being the children of cousins and 
 4.5 per cent of the whole of the deaf. 
 
 These would be the true percentages on the usual 
 assumption that the ratios in "not stated" cases are 
 substantially the same as in the cases stated, but in the 
 present instance there is some reason for supposing 
 that they may be different. 
 
 Some people are sensitive to questions concerning 
 consanguinity in marriage, especially where defective 
 offspring have appeared, and in such cases nonreply 
 would be an easy means of evading the question. It 
 may be possible, therefore, that the proportion having 
 parents cousins may be larger among the "not stated" 
 than the stated cases. However this may be, and 
 whatever interpretation be put upon cases of nonreply, 
 it is obvious that the true percentages, both in the 
 case of parents cousins and parents not cousins, are 
 greater than those noted in the tables, for the reason 
 already given, viz, that these percentages are based 
 upon totals that include the "not stated" cases. 
 
 It also appears that the percentage having parents 
 cousins is greater among the deaf from childhood than 
 the deaf from adult life ; greater among the totally deaf 
 than the partially deaf; and greater among those 
 having a or & deaf relatives than among those who 
 have not (a relatives are brothers, sisters, or ancestors; 
 h relatives are uncles, aunts, cousins, or other relatives 
 
 not a, c, or d; c relatives are sons or daughters; and 
 (Z relatives are husbands or wives). 
 
 The percentage "not stated" is larger among the 
 deaf from adult life than the deaf from childhood ; and, 
 in the case of the deaf from adult life, seems to be 
 proportionally larger the more advanced the age when 
 deafness occurred. This increase is accompanied by 
 a corresponding decrease in the percentage having 
 parents not cousins. The reason for this is not obvious. 
 
 Of those whose parents were cousins, 42.1 per cent 
 were deaf from birth, and only 15 per cent of those 
 whose parents were not cousins. It thus appears that 
 the percentage deaf from birth is nearly three times as 
 great (2.8) among the deaf whose parents were cousins 
 as among those whose, parents were not. 
 
 Of the deaf whose parents were cousins, 53.4 per 
 cent, and of those whose parents were not, 29.9 per 
 cent, have other members of their families deaf (a or b 
 relatives). It thus appears that the percentage hav- 
 ing a or & deaf relatives is nearly twice as great (1.8) 
 among those whose parents are cousins as among those 
 whose parents are not. 
 
 The converse fact also appears, viz, that the per- 
 centage having parents cousins is more than twice as 
 great (2.6) among those who have a or & deaf relatives 
 as among those who have not (relatives, 8.4 per cent; 
 no relatives, 3.2).

 Table xlviii shows that of the deaf whose parents 
 were cousins, the assigned causes to which the largest 
 percentages are attributed are the congenital and he- 
 reditary causes and disease of ear. 
 
 Deaf relatives. —Out of a total of 89,287 deaf, 29,716, 
 or 33.3 per cent, had deaf relatives; 50,765, or 56.8 
 
 per cent, had not; and in 8,806, or 9.9 per cent, the 
 question relating to deaf relatives remained unan- 
 swered (Table 3). It thus appears that one- third of 
 the deaf population of the United States have other 
 members of their families deaf. 
 Where only one member of a family is deaf, there

 is nothing to indicate any inherited predisposition 
 toward deafness in the individual considered ; sporadic 
 deafness may be purely adventitious and accidental. 
 But where two or more members of the same family 
 are deaf, it is a little less likely that the deafness is 
 accidental. It is more probable that in many, if not 
 in most, cases heredity has played a part in the pro- 
 duction of the deafness ; in which case we should look 
 up to the common ancestor of the deaf persons for the 
 initiating cause. 
 
 Where a tendency toward ear trouble exists in a 
 family, it may lie dormant and unsuspected until some 
 serious illness attacks a member of the family, when 
 the weak spot is revealed and deafness is produced. 
 We are not all built like that wonderful one-horse shay 
 that was so perfectly made in all its parts that when at 
 last it broke down it crumbled into dust. When 
 an accident occurs, it is the weak part that gives 
 way, and it would be incorrect to attribute the dam- 
 age to the accident alone and ignore the weakness 
 of the part; both undoubtedly are contributing 
 causes. 
 
 In the case, then, of a deaf person who has deaf rela- 
 tives the assigned cause of deafness may not be the 
 only cause involved, or indeed the true cause at all. 
 It may be the cause simply in the same sense that the 
 pulling of a trigger is the cause of the expulsion of a 
 bullet from a rifle, or a spark the cause of the explosion 
 of a gunpowder magazine; hereditary influences may 
 be involved. 
 
 In considering the subject of deaf relatives it seems 
 advisable to distinguish blood relatives from persons 
 who are relatives simply by marriage; and relatives in 
 the direct line, from collateral or distant relatives. 
 
 In the present report four kinds of deaf relatives are 
 distinguished, which for convenience of reference are 
 designated by the letters a, i, c, and d: a, brothers, 
 sisters, or ancestors (direct line); h, uncles, aunts, 
 cousins, and other relatives not a, c, or d (collateral) ; 
 c, sons or daughters (descendants); d, husbands or 
 wives (relatives by marriage). 
 
 The attempt to distinguish blood relatives from per- 
 sons who are relatives by marriage only has not been 
 entirely successful, for many of the uncles and aunts 
 contained in the b class may be relatives by marriage 
 alone. 
 
 Some of the deaf have a relatives, others have h rela- 
 tives, etc., and still others have both a and h relatives, 
 as well, perhaps, as relatives belonging to the c and d 
 classes. It therefore becomes necessary to effect a 
 classification of deaf relatives so as to distinguish in 
 the tables the various combinations ; for it is obvious 
 that if (without some special arrangement or under- 
 standing in this matter) we should add together the 
 
 totals having a, l, c, or d relatives, the summation 
 would exceed the aggregate.' For example, the total 
 number reported as having deaf relatives is 29,716 
 (Table 3). Of these, 21,660 had a relatives deaf, 8,308 
 had 6 relatives deaf, 677 had c relatives deaf, and 5,051 
 had d relatives deaf. The summation is 35,696, which 
 exceeds the aggregate by 5,980. This, of course, 
 results from the fact that some of those having a 
 relatives had also & or c or cZ relatives, etc. In former 
 censuses, in which deaf relatives were divided into 
 smaller • groups and more of them, the discrepancy 
 between the summation and the aggregate was so 
 great as to render it exceedingly difficult to draw broad 
 conclusions from the statistics. 
 
 In the present report only four kinds of relatives are 
 considered, giving the advantage of larger numbers 
 with which to deal; and a plan of classification has 
 been adopted which enables us to safely add the varie- 
 ties together without duplication, thus facilitating 
 researches relating to deaf relatives. 
 
 Classes. — In classifying deaf relatives we may begin 
 by dividing the deaf into two classes — those who have 
 a relatives and those who have not (Diagram 38).

 Broad groups. — Each of these classes may then be 
 divided into two broad groups (comparable to gen- 
 era) — those who have b relatives and those who have 
 not. 
 
 Subgroups. — Each of these groups may then be 
 divided into two subgroups (comparable to species) — 
 those who have c relatives and those who have not. 
 
 Varieties. — Each of these subgroups may be still 
 further subdivided into two varieties — those who have 
 d relatives and those who have not. 
 
 It will be noticed that the census returns include all 
 possible combinations of, a, b, c, and d. Diagram 38 
 exhibits the whole scheme of classification after the 
 manner of a genealogical chart, with the combinations

 of a, h, c, and d relatives reported in the census ar- 
 ranged in accordance with the classification. 
 
 Tables xlix and l relate to the deaf who have deaf 
 relatives, arranging them into classes, broad groups, 
 subgroups, and varieties in accordance with the clas- 
 sification. 
 
 Table xlix shows the number of the deaf having 
 deaf relatives of the specified classes, by period of life 
 when deafness occurred, degree of deafness, sex, consan- 
 guinity of parents, and sex of the married deaf, and is 
 illustrated by Diagram 39. 
 
 Table l shows the number of the deaf having deaf 
 relatives of the specified classes, by age or period of 
 life when deafness occurred.

 the persons referred to. 
 
 As an illustration of the method of handling deaf 
 relatives symbolically, take a case from Table xlix. 
 
 Suppose we desire to ascertain the number of deaf 
 persons reported to have deaf children; we simply add 
 together all the varieties containing the letter c (the 
 sjrmbol for deaf sons or daughters). The summation 
 of the varieties containing the letter d will give us the 
 
 number having deaf husbands or wives. The varie- 
 ties containing the combination c d will give us those 
 who have both c and d relatives; and — d will give 
 us d relatives without c.

 Nearly one-third of the deaf, 32.1 per cent, are 
 reported as having deaf relatives (a or h). That is, 
 they had deaf brothers, sisters, ancestors, or deaf 
 uncles, aunts, cousins, or naore distant relatives. 
 
 Table li shows that the proportion having deaf 
 relatives (a or &) is greater among the deaf from adult 
 life than among the deaf from childhood, and greater 
 among the partially deaf than the totally deaf. . It is 
 also greater among females than males. It is greatest 
 of all among deaf persons whose parents were cousins 
 (parents cousins, 55.5 per cent; not cousins, 30.6 per 
 cent) . 
 
 In the case of the deaf from birth (Table l) 45.5 per 
 cent had deaf relatives (a or &); so that it seems 
 strange that the proportion having deaf relatives 
 should be smaller among the deaf from childhood 
 (which includes the deaf from birth) than among 
 those who became deaf in adult life. This means, of 
 course, that the percentage having deaf relatives 
 must be still smaller among the noncongenitally deaf 
 from childhood. If we limit our inquiry to the deaf 
 from early childhood (under 5), all of whom belong 
 naturally to the class deaf and dumb, we find that 
 even in their case the proportion having deaf relatives 
 
DEAF RELATIVES. 
 
 131 
 
 is smaller than in the case of the deaf from adult life. 
 From Table l it appears that 9,367 persons who 
 became deaf before reaching the age of 5 had o or & 
 deaf relatives; and these constitute 30.6 per cent of 
 the stated cases, whereas 34.7 per cent of the deaf 
 from adult life had deaf relatives (a or h) (Table li) . 
 
 Of the 9,367 cases referred to above 6,116 were 
 deaf from birth and 3,251 became deaf after birth and 
 before reaching the age of 5 (Table l). Thus 45.5 
 per cent of the deaf from birth, 18.9 per cent of the 
 noncongenitally deaf from early childhood (under 5), 
 and 34.7 per cent of the deaf from adult life had a or & 
 deaf relatives. 
 
 These figures are very striking, and seem to indicate 
 that heredity has played a part in the production of 
 congenital deafness, and also of deafness occurring in 
 adult life (caused principally by catarrh) ; whereas 
 deafness occurring in early childhood after birth and 
 under the age of 5 (dvie principally to scarlet fever, 
 meningitis, and brain fever) is probably adventitious 
 in a large proportion of cases — the sporadic cases 
 constituting 81.1 per cent of the whole. 
 
 The partial deafness of adult life caused by catarrh 
 usually comes on gradually and sometimes affects 
 different members of the same family at or about the 
 
 same age. It is probable, therefore, that a tendency 
 toward catarrh is hereditary in these families, pro- 
 ducing deafness occasionally in different mem- 
 bers by extension to the middle ear ; or the inherited 
 tendency may be toward a local catarrh of the mid- 
 dle ear. 
 
 The noncongenital deafness of early childhood, 
 caused mainly by scarlet fever, meningitis, and brain 
 fever, is more accidental in character, and is probably 
 due chiefly to extraneous causes of an epidemical 
 nature producing total deafness in a large proportion 
 of cases. 
 
 The causes of congenital deafness are very obscure, 
 but it is obvious that in many cases hereditary influ- 
 ences are involved. This is shown by the large pro- 
 portion having deaf relatives. It is also shown by 
 the large proportion of the deaf from birth whose 
 parents were cousins, and by the large proportion of 
 the deaf whose parents were cousins who were born 
 deaf (Table xlvii). 
 
 The most prominent figures of Table l are reduced 
 to percentages in Table lii. In this table the deaf are 
 arranged by age groups when deafness occurred, and 
 the percentage in each age group who have a or & 
 relatives is shown.

 In the noncongenital cases it will be observed that 
 the proportion having a or I relatives deaf is small 
 among the deaf from early childhood (under 5), and 
 then becomes progressively greater where deafness oc- 
 curred in middle childhood (5 to 10) and late childhood 
 (10 to 15), reaching a maximum in youth or adoles- 
 cence (15 to 20). This maximum is substantially re- 
 tained during early manhood (20 to 40), and then the 
 percentage progressively diminishes in middle life (40 
 to 60), declining years (60 to 80), and old age (80 and 
 over). 
 
 • Where deafness occurred during these periods of life 
 the percentages having deaf relatives (a or &) are re- 
 spectively as follows: 18.9, 21.8, 34.7, 40.8, 39.8, 35.5, 
 24.6, and 14 (Table lii). 
 
 The noncongenitally deaf who lost hearing between 
 the ages of 15 and 40 show the largest percentage hav- 
 ing deaf relatives (a or 6)— about 40 per cent. 
 
 The evidence seems to point to heredity as a con- 
 tributing cause of deafness in two classes of deaf per- 
 sons, the deaf from birth (most of whom are totally 
 deaf), and the deaf from catarrh (most of whom are 
 partially deaf). 
 
 Persons who lost hearing from affections of the mid- 
 dle ear, however (including catarrh) , are found mostly 
 in those parts of the country which have the least sun- 
 shine (Map 10), namely, the New England states and 
 the states bordering on the Great Lakes, so that it is 
 probable that climatic conditions have a good deal to 
 do with the production of catarrhal deafness. As the 
 members of the same family would often be exposed to 
 identical climatic conditions, we might reasonably 
 anticipate that catarrhal deafness would sometimes 
 appear in more than one member of the same family, 
 quite independently of any hereditary tendency toward 
 the disease (Map 6).

 THE DEAF. 
 
 The geographic congestion of the deaf from scarlet 
 fever, however, is even more marked (Map 5), and it is 
 not at all unusual for several members of the same 
 family to be ill from scarlet fever at the same time. 
 The deaf from meningitis, too, an epidemic disease of 
 great virulence, show a very marked geographic con- 
 gestion within a limited area of country, having its 
 center in Indiana (Map 8) ; and yet the percentage hav- 
 ing a or 6 relatives deaf is small among the noncon- 
 genitally deaf from early childhood (under 5), most of 
 whom lost hearing from scarlet fever and meningitis, 
 while it is large among the deaf from adult life, most of 
 whom became deaf from catarrh. The hereditary 
 character of catarrhal deafness can hardly be doubted. 
 
 c relatives. — Six hundred and seventy-seven deaf 
 persons are returned who have deaf children; 319 of 
 these were males and 358 females (Table liii). The 
 number of deaf children born to these persons is not 
 stated in the tabulated returns, but we may form some 
 idea of the number by ascertaining how many families 
 were formed by these 677 persons and crediting each 
 family with one deaf child. 
 
 Of the 677 persons reported to have deaf children, 
 437 (250 males and 187 females) appeared among the 
 returns of the married deaf (Table lvii) ; and the re- 
 maining 240 cases (69 males and 171 females) were 
 returned among the single, widowed, or divorced. 
 These 240 cases, therefore, constituted 240 families, 69 
 di which had deaf male heads only, and 171 deaf 
 female heads. 
 
 Of the 437 cases which appeared among the married 
 deaf, 159 were deaf persons with deaf husbands or 
 wives (79 deaf males with deaf wives and 80 deaf 
 females with deaf husbands) (Table lvii), and in 278 
 cases the husbands or wives were not deaf — that is, 
 they were hearing persons. These consisted of 171 
 deaf males with hearing wives and 107 deaf females 
 with hearing husbands. 
 
 If we assume that the deaf males with deaf wives 
 constituted the same families as the deaf females with 
 deaf husbands, then we find a total of 80 families con- 
 taining deaf children in which both the husbands and 
 wives were deaf. 
 
 The 278 cases in which the husbands or wives were 
 not deaf constituted 278 families. Thus the 677 persons 
 reported as having deaf children (Table liii) consti- 
 tuted 598 families ; and if each family had only one deaf 
 child, then there were 598 deaf children having one or 
 both parents deaf. This is a minimum estimate, for 
 some of the families considered undoubtedly contained 
 two or more deaf children. Cases are well known in 
 which two, three, four, five, six, and even seven deaf 
 children have appeared in families in which both the 
 parents were deaf mutes. 
 
 The deaf whose parents were deaf were reported in 
 the original verified census schedules, but unfortu- 
 nately the returns have not been tabulated separately, 
 being simply included in the returns of those having a 
 relatives (deaf brothers, sisters, or ancestors). We are 
 therefore obliged to resort to an estimate; and all we 
 can conclude from the tabulated statements is that 
 more than 598 deaf persons having one or both parents 
 deaf are referred to in the present census. How many 
 more it is now impossible to ascertain without resort to 
 the original schedules. 
 
 Out of a total population of 75,994,575 persons, 
 89,287, or 1,175 per million, were returned as deaf. 
 If, then, the children of deaf persons were no more 
 liable to deafness than the people generally of the 
 United States, we should expect to find 105 deaf per- 
 sons returned whose parents were deaf, for this num- 
 ber would constitute 1,175 per million of the deaf 
 population. But the above facts show that more 
 than 598 deaf children of deaf parents exist in the 
 United States, from which it is obvious that the tend- 
 ency to deafness among the children of deaf persons 
 is more than five and one-half times as great as in the 
 case of the general population of the United States. 
 How much more can not now be ascertained ex- 
 cepting by a special investigation of the original 
 schedules.

 Table liii reveals the fact that the majority of the 
 deaf who have deaf children are persons who became 
 deaf in adult life. This result is somewhat surpris- 
 ing and could not have been anticipated. It only con- 
 firms the conclusion reached upon other grounds that 
 heredity sometimes plays a part in the production of 
 catarrh of the middle ear — the chief cause of deafness 
 occurring in adult life. 
 
 The total number returned as having deaf children 
 is 677, of whom 63.7 per cent were partially deaf and 
 55.5 per cent deaf from adult life; 52.9 per cent' were 
 females; 45.3 per cent had a or & deaf relatives; and 
 4.6 per cent were the offspring of cousin-marriages. 
 
 In the case of the deaf who had deaf children, the 
 proportion having deaf relatives (a or i) is greater 
 among those deaf from childhood than adult life; and 
 greater among the totally deaf than the partially deaf 
 (Table liii) . The opposite is the case among the whole 
 of the deaf (Table li). • 
 
 In both cases, however, the percentage is greater 
 among females than males; and greater among those 
 whose parents were cousins than among those whose 
 parents were not. 
 
 Nearly one-third of the whole deaf population, 32.1 
 per cent, had a or 6 deaf relatives (Table li) ; 
 and nearly one-half, 45.3 per cent, of the deaf 
 who had deaf children had a or 6 relatives deaf 
 (Table liii). 
 
 d relatives. — Out of a total of 89,287 deaf, 5,051 had 
 deaf husbands or wives (d), 75,430 had not, and in 
 8,806 cases the question relating to deaf relatives 
 remained unanswered (Table xlix). 
 
 We can not assume that the 75,430 persons referred 
 to above had hearing husbands or wives, for the fig- 
 ures include the whole of the deaf — the single as well 
 as the married, widowed, and divorced. Even in the 
 case of the 5,051 deaf persons who had deaf husbands 
 or wives {d), we can not assume that the deaf husbands 
 or wives reported were all living at the time the cen- 
 sus was taken; for only 4,965 appear in the returns of 
 the married (Table xlix), so that the remaining 86 
 were either widowed or divorced. 
 
 Table liv shows the deaf who had deaf husbands or 
 wives (d), by deaf relatives (a, b, or c); by period of 
 life when deafness occurred, degree of deafness, sex, 
 and consanguinity of parents.

 From Table liv it appears that of the 5,051 deaf 
 persons who had deaf husbands or wives, 88.5 per cent 
 were deaf froiji childhood, 9.6 per cent were deaf from 
 adult life, and in 1.9 per cent of the cases the period of 
 life when deafness occurred was unknown; 83 per cent 
 were totally deaf and 17 per cent partially deaf; 50.1 
 per cent were males and 49.9 per cent were females; 
 5.2 per cent were the offspring of cousin-marriages, 
 89.7 per cent were not the offspring of cousins, and in 
 5.1 per cent of the cases the question relating to con- 
 sanguinity of parents remained unanswered; 29.2 per 
 cent had deaf relatives (a or 6) and 70.8 per cent had 
 no (a or 6) deaf relatives; 3.3 per cent had deaf children 
 (c d) and 96.7 per cent had no deaf children ( — d) — that 
 is, they had either hearing children or no children at all. 
 
 Table liv shows that in the case of the 5,051 per- 
 sons reported to have deaf husbands or wives, the vast 
 majority were deaf from childhood (88.5 per cent). 
 
 and the vast majority were totally deaf (83 per cent). 
 This, taken in connection with the fact of the nearly 
 equal division of the sexes, leads to the inference that 
 in most of the cases of intermarriage of deaf persons 
 with one another both of the parties to the marriage 
 were deaf from childhood, and both totally deaf.. 
 Most of these persons lost hearing before reaching the 
 age of 5 (Table lvii), and belonged, naturally, to 
 the class deaf and dumb ; so that these unions consist 
 largely of intermarriages of deaf mutes with one 
 another. 
 
 The married deaf. — The figures with which we have 
 hitherto been dealing relate to the whole of the deaf, 
 including the single, married, widowed, and divorced. 
 Tables lv, lvi, lvii, and lviii relate to the married deaf 
 alone and to conditions of marriage that affect the pro- 
 duction of deaf offspring. Tables lvi and lvii sum- 
 marize the detail figures given in Table lv.

 1 Percentage not given where aggregate is less than 100. 
 
 From Table lvii it appears that 34,206 married 
 deaf persons were reported in the census of 1900. Of 
 these, 57.7 per cent were males and 42.3 per cent were 
 females; 37.8 per cent were deaf from childhood 
 (under 20), 58.5 per cent became deaf in adult life, 
 and in 3.7 per cent of the cases the period of life when 
 deafness occurred was unknown. 
 
 Of the 12,924 cases deaf from childhood, 51.5 per 
 cent were males and 48.5 per cent were females. Of 
 the 20,030 cases deaf from adult life, 61.6 per cent 
 were males and only 38.4 per cent were females 
 
 (Tables lv and lvi). It thus appears that the 
 majority of the deaf who marry are males; and the 
 disproportion of the sexes in this respect is most 
 manifest in the case of the deaf from adult life, of 
 whom 61 .6 per cent were males. 
 
 Out of a total of 34,206 married deaf persons, 31,334 
 answered the question relating to deaf relatives and 
 2,872 did not (Table lvii). The following percentages 
 relate to the stated cases : 
 
 a or b relatives. — 10,888, or 34.7 per cent, of the 
 married deaf had deaf brothers, sisters, ancestors, 
 
DEAF RELATIVES. 
 
 139 
 
 uncles, aunts, cousins, or more distant relatives, and 
 20,446, or 65.3 per cent, had no a or & deaf relatives 
 (Table lvii). 
 
 c relatives.— iST , or 1,4 per cent, of the married 
 deaf had deaf children, and 30,897, or 98.6 per cent, 
 had no deaf children— that is, they either had hearing 
 children or no children at all (Table lvii). 
 
 d rek/nvs.— 4,965, or 15.8 per cent, of the married 
 deaf had deaf husbands or wives, and in 26,369 cases, 
 or 84.2 per cent, the husbands or wives were not 
 deaf — that is, they were hearing persons (Table lvii). 
 
 Of the 4,965 married deaf who had deaf husbands 
 or wives, 4,394, or 88.5 per cent, were deaf from 
 childhood (under 20); 477, or 9.6 per cent, became 
 deaf in adult life; and in 94 cases, or 1.9 per cent, 
 the period of life when deafness occurred was unknown 
 (Table lvii). 
 
 Of the 26,369 married deaf whose husbands or 
 wives were not deaf, 7,997, or 30.3 per cent, were deaf 
 from childhood; 17,688, or 67.1 per cent, were deaf 
 from adult life; and in 684 cases, or 2.6 per cent, the 
 period of life when deafness occurred was unknown 
 (Table lvii). 
 
 Thus the vast majority of the married deaf who 
 had deaf husbands or wives (88.5 per cent) were deaf 
 from childhood, and about two-thirds of the married 
 deaf whose husbands and wives were not deaf (67.1 
 per cent) were persons who lost hearing in adult life. 
 It will also be noticed that the majority of the married 
 deaf who had deaf husbands or wives (68.3 per cent) 
 were deaf from early childhood (under 5) (Table lvii), 
 and belong naturally to the class deaf and dumb. 
 They represent intermarriages of deaf-mutes with 
 one another. 
 
 In studying the marriages of the deaf, and the 
 influence of these marriages upon the offspring, the 
 plan has been adopted of calculating the percentage 
 having deaf children upon the basis of a total which 
 includes the males and females considered, instead 
 of noting separately the percentage of males and 
 the percentage of females having deaf children. The 
 percentage derived from the summation of the two 
 classes is more reliable than that derived from either 
 class alone, because based upon larger numbers. And 
 the percentages express not merely the proportion of 
 deaf persons who have deaf children, but the propor- 
 tion of families containing deaf children. This is an 
 important point and worthy of special consideration. 
 
 In regard to the absolute numbers involved it will 
 of course be noticed that the figures expressing the 
 number of deaf persons who have deaf children do 
 not represent the number of deaf children born to 
 them, even if we assume that each person had only 
 one deaf child — which would be an underestimate. 
 Some of the males and females included were undoubt- 
 edly the parents of the same children— two parents 
 to one child. Nor do these figures represent the number 
 
 of families having deaf children, which is necessarily 
 less than the number of married persons composing 
 them; and yet the percentage of persons having deaf 
 children expresses the percentage of families having 
 deaf children, even though the absolute number of 
 families may be unknown. This will be obvious from 
 the following considerations: 
 
 Let there be one hundred families, and let one of 
 them contain deaf children; then the proportion of 
 families having deaf children is 1 per cent. 
 
 Case 1 . — Now assume that in each of these families 
 only one of the married partners was deaf; then 100 
 married deaf persons in all would be recorded, of 
 whom 1 had deaf children. In this case the propor- 
 tion having deaf children would be 1 per cent, thus 
 corresponding with the percentage of families. 
 
 Case 2. — Next assume that in each of the families 
 considered both of the married partners were deaf; 
 then 200 married deaf persons in all would be recorded, 
 of whom 2 had deaf children. But the proportion 
 having deaf children would remain at 1 per cent, 
 thus still corresponding with the percentage of 
 families. 
 
 Case 3. — These are extreme cases, and there is only 
 one other supposable case between them, namely, that 
 in some of the families the married partners were both 
 deaf, and that in others only one of the married part- 
 ners was deaf. In this case also it is obvious that the 
 percentage of deaf persons having deaf children would 
 correspond to the percentage of families. 
 
 In the case of the married deaf we do not know ex- 
 actly the total number of families involved or the exact 
 number of families containing deaf children; but still 
 we can estimate these numbers with a sufficient ap- 
 proximation to the truth to enable us to test the accu- 
 racy of the conclusions noted above. 
 
 Case 1. — The 26,369 married deaf persons whose 
 husbands or wives were not deaf constituted, of course, 
 26,369 families, and the 278 persons among them who 
 had deaf children also evidently constituted 278 fam- 
 ilies; so that here the percentage of persons having 
 deaf children is obviously the same as the percentage 
 of families containing deaf children. 
 
 Case 2. — In the case of the 4,965 married deaf per- 
 sons who had deaf husbands or wives, 2,501 were males 
 and 2,464 were females; so they constituted at least 
 2,501 families. There may have been more, but cer- 
 tainly not less. In the case of the 159 persons among 
 them who had deaf children 79 were males and 80 were 
 females; so that these persons constituted not less tha.n 
 80 families.

 THE DEAF. 
 
 Oase 3. — In the case of the 31,334 married deaf per- 
 sons constituting the stated cases in Table lvii, 18,091 
 were males and 13,243 were females. These persons 
 therefore constituted at least 18,091 famihes. In the 
 case of the 437 persons among them who had deaf 
 children 250 were males and 187 were females; so that 
 they constituted at least 250 families. There may 
 have been more, but certainly not less.

 Conditions affecting the production of deaf offspring. — 
 Table lvii shows that out of 31,334 married deaf per- 
 sons 437, or 1.4 per cent, had deaf children. This 
 means that on the average 1.4 per cent of the mar- 
 riages contracted by deaf persons are productive of 
 deaf offspring. Out of every 100 families formed by 
 these marriages 1.4 contain deaf children. 
 
 Sex. — Out of 18,091 married deaf males 250, or 1.4 
 per cent, had deaf children. Out of 13,243 married 
 deaf females 187, or 1.4 per cent, had deaf children 
 (Table lvii). 
 
 From this it appears that the sex of the deaf partner 
 in marriage does not appreciably affect the proportion 
 having deaf children, although it should be noticed 
 that in the case of those having aid deaf relatives the 
 percentage having deaf children is more than twice as 
 great among the males as among the females (males, 
 12.7; females, 6) (Table lviii). The totals, however, 
 on which these latter percentages are based are com- 
 paratively small, very little exceeding 100; whereas 
 the percentages for the whole of the married males and 
 females are based upon many thousands of cases, and 
 show no difference in this respect between the males 
 and females. The sex of the deaf parent alone, with- 
 out other complicating conditions (like a h d deaf rela- 
 tives) does not seem to be a factor affecting the pro- 
 portion having deaf children.

 Degree of deafness. — Out of 8,022 married deaf per- 
 sons who were totally deaf 190, or 2.4 per cent, had 
 deaf offspring; and out of 23,312 married deaf persons 
 who were partially deaf 247, or 1 . 1 per cent, had deaf 
 children (Table lvii) . 
 
 It thus appears that the proportion having deaf off- 
 spring is more than twice as great among the totally 
 deaf as among the partially deaf married persons. 
 Table liii shows that the majority ot the deaf who 
 iave deaf offspring are partially deaf; but this evi- 
 dently results not from any greater liability on their 
 part to produce deaf offspring, but from the fact that 
 the partially deaf are more numerous than the totally 
 
 deaf in the whole deaf population. Among the mar- 
 ried deaf 25,875 were partially deaf and only 8,331 
 totally deaf (Table lvii) .

 Period of life when deafness occurred. — Out of 12,391 
 married deaf who were deaf from childhood (under 20) 
 238, or 1.9 per cent, had deaf children. Out of 18,165 
 married deaf who became deaf in adult life 188, or 1 
 per cent, had deaf children (Table lvii) . 
 
 Out of 5,459 married deaf persons who lost hear- 
 ing before the age of 5, 159, or 2.9 per cent, had deaf 
 children. Of these, 1,815 were congenitally deaf and 
 3,644 became deaf after birth and before, reaching the 
 age of 5. Of the congenitally deaf cases, 91, or 5 per 
 cent, had deaf children. Of the noncongenitally deaf 
 cases, 68, or 1.9 per cent, had deaf children (Table 
 lvii). 
 
 It thus appears that the tendency to transmit the 
 defect is greater among the deaf from childhood than 
 the deaf from adult life. It is still greater among the 
 deaf from early childhood (under 5), all of whom be- 
 long naturally to the class deaf and dumb, and great- 
 est of all among the deaf from birth (the congenital 
 cases) .

 a, I, or d relatives. — Out of 14,407 married deaf per-

 cent, had deaf children. Out of 16,927 who had no 
 deaf relatives (a, b, or d), 151, or 0.9 per cent, had 
 deaf children (Table lvii). 
 
 It thus appears that the proportion having deaf 
 children is more than twice as great among the mar- 
 ried deaf who have deaf relatives (a, b, or d) as among 
 those who have no a, b, or d deaf relatives.

 a relatives. — There were 9,308 married deaf persons 
 who had deaf brothers, sisters, or ancestors. Of these, 
 189, or 2 per cent, had deaf children, but it will be 
 observed that the total includes all who have a rela- 
 tives. Some of the persons referred to had also b or 
 d relatives. To ascertain the effect of the a element 
 alone we should exclude the b and d elements from 
 consideration. Out of 6,577 married deaf who had a 
 
 relatives alone without b ox d relatives (a ), 84, 
 
 or 1.3 per cent, had deaf children (Table lvii). 
 
 b relatives. — Out of 3,344 married deaf persons who 
 had uncles, aunts, cousins, or other more distant rela- 
 tives deaf (6), 72, or 2.2 per cent, had deaf children; 
 but the total includes persons who had also a or <^ rel- 
 atives. Excluding the a and d elements, we find that

 1,343 of the married deaf had h relatives alone, with- 
 out a or d relatives ( — h — ) ; and of these, 14, or 1 
 per cent, had deaf children (Table lvii). 
 
 d relatives. — Out of 4,965 married deaf who had 
 deaf husbands or wives, 159, or 3.2 per cent, had deaf 
 children. The total includes persons who had a or 6 
 deaf relatives; and if we exclude these, we find 3,519 
 married deaf with deaf husbands or wives but no a or 
 
 h relatives deaf ( d). Of these, 77, or 2.2 per 
 
 cent, had deaf chiklren (Table lvii). 
 
 Even in this case, however, we have not eliminated 
 the effect of a or i relatives; for many of the deaf 
 husbands or wives considered undoubtedly had a or & 
 deaf relatives. The census returns give us no infor- 
 mation concerning these husbands or wives beyond 
 the bare fact that they were deaf. 
 
 No a, i, or d relatives. — Out of 16,927 married deaf 
 persons who had no a, h, or d relatives deaf, 151, or 
 0.9 percent, had deaf children (Table lvii). 
 
 In considering the significance of deaf relatives as 
 an indication of the liability of a deaf person to pro- 
 duce deaf offspring the following seems to be the 
 order of importance of the a, h, and d elements con- 
 sidered separately: The largest proportion having 
 deaf children is found among the married deaf who 
 have deaf husbands or wives (but no a or 6 relatives) ; 
 next come those having a relatives (but not h or d); 
 then those having i relatives (but not a or d). The 
 smallest proportion having deaf children is found 
 among those who have neither a, h, nor d relatives: 
 
 d - - 2.2 
 
 a - ---- 13 
 
 — b — 10 
 
 0.9 
 
 Combinations of a, i, and d relatives. — From these 
 facts we would naturally anticipate that the largest 
 proportion having deaf children would be found 
 among those having both a and h relatives who mar- 
 ried deaf husbands or wives, and that the proportion 
 having deaf children would be successively smaller 
 where other combinations of a, h, or d occurred in the 
 
 following order: ah d; a — d; — i d; d; 
 
 ai — ; a ; — 6 — ; • And this we find 
 
 to be the case. The following figures show the per- 
 centage of married deaf persons having deaf children 
 
 where these combinations of deaf relatives occurred 
 (Table Lviii).

 We should also expect to find a still larger percent- 
 age having deaf children where the ah d elements are 
 combined with other elements found to be significant in 
 this connection — like total deafness and deafness oc- 
 curring at an early period of life, and this we find to 
 be the case. For example: Table LVi records 181 
 married deaf persons who were totally deaf from birth, 
 and who had a h d relatives deaf. Of these, 18, or 
 9.94 per cent, had deaf children. 
 
 Totally deaf from birth, ab d 9. 94 
 
 The significance of the percentages will be appar- 
 ent by applying the results to the whole married popu- 
 lation of the United States. We can calculate how 
 many families containing deaf children would be found 
 among the married people of the United States if they 
 had the same liability to the production of deaf off- 
 spring that is found in the case of the married deaf. 
 
 More than 13,000,000 married males are returned 
 in the census of 1900, and more than 13,000,000 mar- 
 ried females. If only 1 per cent of these persons 
 should have deaf children, we would have in the 
 United States more than 130,000 families containing 
 deaf children. 
 
 130,000 equal 1 per cent. 
 
 260,000 equal 2 per cent. 
 
 390,000 equal 3 per cent. 
 
 520,000 equal 4 per cent. 
 
 650,000 equal 5 per cent. 
 
 780,000 equal 6 per cent. 
 
 910,000 equal 7 per cent. 
 
 1,040,000 equal 8 per cent. 
 
 1,170,000 equal 9 per cent. 
 
 1,300,000 equal 10 per cent. 
 
 For convenience of reference the percentages hav- 
 ing deaf children for each of the classes of deaf per- 
 sons mentioned in Table lviii are given below, where

 The above investigation relating to the marriages 
 of the deaf and the effect upon the offspring affords 
 a convincing demonstration of the fact that the laws 
 of heredity which are known to apply to animals 
 also apply to man. This has generally been assumed, 
 but the above investigation demonstrates the propo- 
 sition. 
 
 Present age. — The present age of the deaf is given in 
 Table lix, by various classifications. 
 
 About one-fifth of the deaf are under 20 years 
 of age; of these, over 75 per cent are totally deaf, 
 while among the number over 20, only about 33 per 
 cent are totally deaf. 
 
 The per cent who speak is very much larger among 
 those over 20, although the per cent who have attended 
 school is larger for those under 20. 
 
 The figures presenting the relation of the present 
 age of the deaf to the age when deafness occurred are 
 found in Table lx. 
 
 Of the number now under 20, the largest per cent 
 are the deaf from birth. Of those over 20, the largest 
 per cent lost their hearing between the ages of 20 and 
 40. 
 
 The present age of the totally deaf from early child- 
 hood is compared with the present age of the entire 
 population in Table lxi. 
 
 Table Lxn gives the geographic distribution of the 
 deaf, by present age groups.

 The marital condition of the deaf is clearly presented 
 in Table lxiii. As might naturally be expected, the 
 largest number of single persons is found among those 
 who were deaf from childhood, while the proportion 
 of married and widowed is especially large among 
 those who became deaf in adult life. Naturally 
 enough, also, the majority of those who remained sin- 
 gle are totally deaf, more than two-thirds of those who 
 are reported single being in the totally deaf class, 
 while three-fourths of those who are married are only 
 partially deaf. In the matter of sex males are in the 
 majority in both the single and married class, but 
 strangely enough there are almost twice as many wid- 
 ows as widowers. This may arise from the fact that 
 the chance of remarriage is doubtless smaller for a 
 deaf woman than for a deaf man, but the principal 
 reason is probably to be found in the occurrence of 
 deafness in old age among the many cases where the 
 wife survives the husband. Whatever the cause of 
 this preponderance may be, it is one of the interesting 
 facts developed by this table. 
 
 By contrasting similar figures relating to marriage- 
 able population for the deaf and the total population, 
 the following interesting percentages appear :

 Widowed.

 The proportion single and married among the deaf 
 is slightly smaller than among the total population, 
 while the proportion widowed is very much larger. 
 Eliminating the deaf under 15 years of age consider- 
 ably decreases the proportion single and increases the 
 proportion married. 
 
 The relation of deafness to marital condition is 
 shown in detail in Table 37. 
 
 School attendance. — ^Table lxiv distributes the deaf 
 by age or period of life when deafness occurred, .degree 
 of deafness, sex, and race in relation to school attend- 
 ance. Unfortunately for purposes of comparison in 
 the total population the deaf are not classified accord- 
 ing to literacy and illiteracy. Attendance at school 
 is in reality a most unsatisfactory test, since many per- 
 sons who have not attended school may be literate, 
 and among the deaf it is likely that a large proportion 
 would come within this class. However, even if it be 
 assumed that only those of the deaf who have attended

 school are literate as a class, the deaf show compara- 
 tively little illiteracy. In 79,274 cases the question 
 as to attendance at school was answered, 65,717, or 
 73.6 per cent, attending, and 13,557,. or 15.2 per cent, 
 not attending; while in 10,013 cases no answer was 
 received. There are practical reasons, indeed, why 
 illiteracy among deaf persons should be less than 
 among the general population, since writing neces- 
 
 sarily forms for many the principal medium of com- 
 munication. Persons who are totally deaf usually 
 employ the sign-language or communicate by writing, 
 the acquisition of one being about as easy as the 
 other. In the case of the deaf, therefore, there is a 
 definite and personal reason which operates against 
 illiteracy. The white race shows a much larger per 
 cent attending school than the colored.

 Those whose present age is under 20 show 77.8 per 
 cent who have attended school, as against 72.6 per cent 
 of those 20 years of age and over. 
 
 Table lxv shows the deaf who have attended school, 
 by kind of school, age or period of life when deafness 
 occurred, degree of deafness, sex, race, and present age. 
 
 In 20,619 cases the kind of school attended was not 
 stated. Of those who did state kind of school, the 
 larger part had attended special schools. This was to 
 be expected, in view of the fact that the great majority 
 of those who reported schooling (40,448 out of 65,717) 
 became deaf in childhood. 
 
 Of the totally deaf, 77.5 per cent, and of the partially 
 deaf only 6.8 per cent, attended special schools. 
 
 A slightly greater proportion of the males than of 
 the females attended special schools, 39 and 37.5 per 
 cent, respectively, the latter exceeding in the propor- 
 tion who have attended other schools. 
 
 Of those who lost hearing before 5 years of age, 
 81.5 per cent attended special schools, this propor- 
 tion decreasing rapidly as age when deafness occurred 
 increases. The percentage who did not state kind of 
 school attended increases as the age when deafness 
 occurred increases.

 employed.

 These figures indicate that deafness is a drawback 
 to some extent in securing employment; but they also 
 show that the deaf as a class are by no means a burden 
 upon the community. Few of the deaf who are under 
 20 years of age are engaged in gainful occupations 
 (Table lxxii) ; but this is no discredit to them, for the 
 vast majority of these cases are attending school (Table 
 LXiv) . Of those over 20 years of age 43 per cent are 
 engaged in gainful occupations — for Table lix shows a 
 total of 70,602 who are over 20 years of age, and Table 
 Lxxiii shows that 30,353 of these, or 43 per cent, are 
 engaged in gainful occupations. 
 
 Table lxvi shows the number and per cent of the 
 deaf in each occupation contrasted with the per cent

 Of the deaf gainfully employed, 89.7 per cent are 
 found in the three groups in which perfect or even 
 partial hearing is not essential, while in the two 
 remaining groups— trade and transportation and pro- 
 fessional service — which require hearing and speaking 
 power, only a small proportion of the deaf (10.3 per 
 cent) report employment.

 The percentage for professional service is high 
 because it includes teachers, professors in colleges, etc., 
 and artists and teachers of art. The teachers show 
 a rery large per cent totally deaf (206 out of 294), 
 the majority of whom probably are instructors in 
 schools for the deaf. In nearly every other kind of 
 professional service the totally deaf constitute a very 
 small minority

 The deaf who have attended school show a much 
 larger per cent of their number pursuing gainful 
 occupations than of those who have not attended 
 school. 
 
 The kind of employment — whether skilled or un- 
 skilled — is also largely determined by school attend- 
 ance. In Table lxix the number in each group of 
 occupations is distributed according to schooling.

 Those engaged in professional service, manufactur- 
 ing and mechanical pursuits, and trade and transpor- 
 tation show a very large percentage of their number 
 schooled, ranking in this respect in the order named; 
 while those in agricultural pursuits show next lowest, 
 and those in domestic and personal service, the 
 smallest percentage schooled. In the last two classes 
 of occupations lack of schooling is no great drawback, 
 while in the remaining three it is almost a total 
 disqualification. 
 
 Unfortunately for purposes of comparison, the kind 
 of school was not stated in over one-third of the cases. 
 This failure to state kind of school was particularly 
 marked among those in agricultural and in manufac- 
 turing and mechanical pursuits. 
 
 In Tables lxxii, lxxiii, and lxxiv the occupations 
 of the deaf are given in detail.

 From this table it appears that the deaf from child- 
 hood are more self-supporting than the deaf from adult 
 life. 
 
 This is specially surprising when we consider the 
 fact that the deaf from childhood include practically 
 all of the deaf and dumb, and that most of them are 
 totally deaf; whereas the deaf from adult life include 
 none of the deaf and dumb (at least substantially none), 
 and most of them are only partially deaf. 
 
 Of the deaf from childhood who were over 10 years 
 of age, 40. 6 per cent were gainfully employed, and of the 
 deaf from adult life only 36.8 per cent (Table lxx). 
 
 These figures, however, do not fully express the dis- 
 crepancy between the two classes in this respect; for 
 all of the deaf from adult life were, of course, 20 years 
 of age or over, because they did not lose hearing until 
 after reaching that age; whereas many of the deaf from 
 
148 
 
 THE DEAF. 
 
 childhood (13,786) were between 10 and 20 years of age, 
 and comparatively few of these were earning their 
 livelihood, because most were in school. 
 
 Of the deaf from childhood who were 20 years of 
 age or over, the majority (51.6 per cent) were gainfully 
 employed, against 36.8 per cent of the deaf from adult 
 life (Table lxx). 
 
 Of the totally deaf who were 20 5'ears of age or over 
 (most of whom were deaf from childhood) 50.1 per 
 cent were earning their livelihood, but only 39.5 per 
 cent of the partialh' deaf (most of whom became deaf 
 in adult life). (Table lxx.) 
 
 The deaf from adult life are undoubtedh* better 
 equipped by nature for the task of earning a livelihood, 
 for most of them possess perfect speech and partial 
 hearing; and yet the deaf "from childhood seem to be 
 more successful in this respect. 
 
 The explanation for this apparentlj^ anomalous con- 
 dition of affairs seems to lie in the fact that manj^ per- 
 sons who become deaf in adult life fail to accommodate 
 themselves to the new condition of deafness. They lose 
 their positions on account of increasing deafness; and 
 feeling themselves to be too old to begin life all over 
 again in their crippled condition by seeking some new 
 occupation with which deafness would not interfere,, 
 they lose heart and drop out of the struggle, becoming 
 dependent upon their friends for support, or living upon 
 the savings of former years, without entering into new 
 pursuits. 
 
 In the case of the deaf from childhood, however, the 
 accommodation to the environment has become complete 
 before the dawn of adult life. Many of these persons 
 have never experienced any other condition than that 
 of deafness; and most of them enter upon the duties 
 and responsibilities of adult life with that feeling of 
 buoyancy and hope that is so characteristic of youth. 
 
 Nor should we neglect to notice in this connection 
 the powerful influence exerted on the deaf from child- 
 hood by the special schools which have been established 
 for their benefit. 
 
 The sentiment is very early instilled into their minds 
 that these schools are not in any sense "asylums" or 
 "charitable institutions," but simply "schools" for 
 their education, analogous to the ordinary public 
 schools of the country; and that they themselves are 
 not — and never should be — objects of charity. The 
 spirit of dependence is discouraged; and every effort 
 made to stimulate a spirit of independence and self- 
 help. The puplils are led to believe that it is the duty 
 of every deaf boy and girl to learn some means of 
 livelihood; and that a stigma attaches to those who be- 
 come a burden upon their friends or the public. 
 
 Sentiment counts for a great deal with the young; 
 but the special schools go further than this by provid- 
 ing manual training and art instruction for advanced 
 pupils.^ 
 
 These schools very generally teach the use of tools 
 and give manual training in the form of sloyd. Mechan- 
 ical drawing, too, and art instruction are given to those 
 who manifest abilities in these lines. Many of our 
 schools support special trade shops in which specific 
 occupations are taught, like shoemaking, cabinetmaking, 
 etc., although it is perhaps doubtful whether this 
 specialization of manual training during school life is 
 of as much value to the deaf as instruction of a more 
 general character, embracing elements that are common 
 to a number of trades. Comparativelv few of the deaf 
 from childhood pursue in adult life the specific occupa- 
 tions they were taught in school; and the verj^ great 
 variety in the occupations actuallj^ pursued seems to 
 render diversity rather than specialization a desirable 
 aim during the school period, leaving specialization 
 into a specific occupation to come later in life, through 
 actual work in ordinary shops, which are more likely 
 to be up-to-date in their methods of work than the 
 trade shops of the schools, which do not feel the stimu- 
 lating effects of competition. 
 
 The Census tables relating to occupation reveal the 
 astonishing fact that there are extremely few occupa- 
 tions pursued bj' the people of the United States in 
 which deaf persons do not find employment. This is 
 not only surprising, but at the same time encouraging, 
 as widening the scope of possible usefulness for the 
 deaf. 
 
 There can be no question that the industrial training 
 provided bj' our special schools has been of material 
 assistance to their pupils in securing employment in 
 adult life, and it is specially worth3' of notice in this 
 connection that very many of the deaf from childhood 
 have had the opportunitj^ of taking this training, whereas 
 hardly any of the deaf from adult life have attended 
 special schools.

 Out of 35,924 persons M'ho became deaf in adult life, 
 only 185 attended special schools; whereas out of 50,296 
 persons deaf from childhood, 25,071 received tniiuing 
 in special schools (including 225 who attended both 
 special and other schools). (Table 2.) 
 
 From this it appears probable that our special schools 
 for the deaf are mainly responsible for the fact that the 
 deaf from childhood no longer constitute a dependent 
 class. The majority, or 51.6 per cent, are gainfully 
 employed in adult life. The percentage rightfully enti- 
 tled to 1)e regarded as self-supporting is even larger 
 than this, for the chief occupation reported bj' married 
 females (" ' keeping house ") has not been included among 
 gainful occupations.

 Table lxxi shows the deaf who are 10 years of 
 age or over, by ability to speak and degree of deaf- 
 ness; giving the number and percentage of each class 
 who are employed in gainful occupations. 
 
 Out of 62.658 deaf persons 10 years of age or over 
 who were able to speak, 23,996, or 38.3 per cent, were 
 employed in gainful occupations. Out of 20,730 deaf 
 persons who were unable to speak, 8,146, or 39.3 per 
 cent were gainfully employed (Table lxxi). 
 
 It thus appears that the deaf and dumb, as a class, 
 are more self-supporting than the deaf who speak. 
 
 This is rather a startling conclusion; and it is very 
 easy to draw false inferences from the fact. It can 
 hardly be doubted that the deaf who speak, even 
 imperfectly, have some advantage over those who 
 can not speak at all; so that it is obvious that the 
 above result arises, not from the difference of speaking 
 power, but from other differences not specified in the 
 
 table. 
 
 The fact of the matter is that all of the deaf and dumb 
 were deaf from childhood; whereas the majority of the 
 deaf who speak lost hearing in adult life. The deaf 
 from adult life are inferior in self-supporting power- 
 not of course, because they can speak, but because 
 
 of other conditions referred to more particularly in 
 remarks concerning Table lxx ; and the deaf and 
 dumb are superior in this respect — not because they 
 are dumb, but because of the industrial ti-aining they 
 have received in special schools. 
 
 In order to ascertain the influence of speech upon 
 employment, we should eliminate the deaf from adult 
 life and study the occupations of the deaf from child- 
 hood who speak well, imperfectly, or not at all, so as 
 to have no other substantial point of difference between 
 the classes considered, excepting their ability to speak. 
 Unfortunately the tabulated returns do not give us the 
 information desired. 
 
 We can ascertain the period of life when deafness 
 occurred, and the present age, of the deaf who speak 
 well, imperfectly, or not at all; and also of the deaf 
 who are gainfuUv employed, but we have no tables 
 correlating the results. ^Ye may gain some light upon 
 the subject, however, from the consideration of the 
 fact that the totallj^ deaf consist mainly of persons deaf 
 from childhood, so that the totally deaf cases noted in 
 Table lxxi were probably all deaf from childhood. 
 Of those who could speak well, 40 per cent were em- 
 ployed in gainful occupations; whereas only 34.7 per 
 cent of those who were deaf and dumb were gainfully 
 employed. The ability to speak well was evidently of 
 advantage. 
 
 The advantage is not so obvious in the case of the 
 totally deaf who speak imperfectly, of whom only 32 
 per cent were gainfully employed. It should be re- 
 membered, however, that in these cases we are dealing 
 largely with persons who have acquired speech arti- 
 ficially by instruction in school, and that the table 
 includes manj' persons who are between 10 and 20 5''ears 
 of age. 
 
 Articulation teaching is of so comparatively recent 
 origin that most of the deaf who have acquired speech 
 artificially by instruction in schools are still quite 
 young, few having passed middle life; whereas the deaf 
 and dumb, and the deaf who speak well, contain persons 
 of all ages — even up to extreme old age. 
 
 The difference between the three classes in respect to 
 age may be illustrated by taking the aggregates given 
 in Table lxxi (composed of persons 10 j^ears of age or 
 over), and showing the number and percentage who 
 are 20 years of age or over:

 THE DEAF. 
 
 As more than 94 per cent of the aggregate gainfully 
 employed are 20 years of age or over, it follows that 
 the number 20 years of age or over who are gainfully 
 employed among the three classes named (the deaf who 
 speak well, imperfectly, or not at all) would be only 
 slightly changed from the figures of the table (Table 
 Lxxi); but the percentage gainfully employed would 
 be considerably increased in the case of the deaf who 
 speak imperfectly— in fact, almost doubled— because it 
 would be based upon a smaller total little more than 
 half its former value (59 per cent). 
 
 Not only does ability to speak affect the opportunity 
 for engaging in pursuits in general, but it also, in a 
 large measure, determines the choice of occupation. 
 The following percentages are taken from Table 47, and 
 show the percentage of the deaf who speak well, imper- 
 fectlj', or not all, who are engaged in the principal 
 groups of occupations:

 The advantage of speech is most manifest in agricul- 
 tural pursuits, professional service, and trade and trans- 
 portation; the percentage employed in these occupations 
 being greatest among those who speak well, least among 
 those who do not speak at all, and intermediate among 
 those who speak imperfectl}-. On the other hand, speech 
 does not seem to be of so much consequence in domes- 
 tic and personal service and manufacturing and me- 
 chanical pursuits, the order of the percentages being 
 reversed.
