Steam, 2,136 These figures, though they include day as well as evening students, but well repay analysis. Consider first Machine Construction and Drawing, Building Construction, Naval Architecture, and Principles of Mining, and assume that all students in Applied Mechanics and Steam are taking one or other of these. Let it be granted that such students require DIFFICULTIES AND SHORTCOMINGS 79 instruction in Mathematics and Geometry. In round numbers we have : Number of students taking Machine Con- struction and Drawing, Building Con- struction, Naval Architecture, and Principles of Mining, ... 17,000 Number of students taking Mathematics, - 1 3,000 Number of students taking Geometry, - 3,000 Allowing for the fact that students in Machine Construction and Drawing, Building Construction, Naval Architecture, and Principles of Mining, are almost entirely engaged in the respective industries, while students in Mathematics are not necessarily so engaged, the disparity is considerable. The case of Geometry is serious. This subject has for over thirty years been compulsory for Whitworth scholarships and exhibitions, and the prospectus of every technical school of note insists on a knowledge of Geometry as a basis of successful work in the subjects compared. If this regulation is not honoured more in the breach than in the observance, the state of affairs in the rest of the country must be bad indeed. In fact, the writer's own observations lead to the belief that teachers of this subject are becoming scarce, and the following figures showing the number of papers worked during three years fully account for it : 1900. 1901. 1902.1 Number of papers in Subject I. worked, - - - 11,628 4,691 2,997 1 Examinations in the elementary stage of science subjects became optional in 1901. The percentage drop in papers worked in all subjects was 38, in Geometry, 60 per cent. 80 TECHNICAL EDUCATION IN EVENING SCHOOLS Examine next the case of Steam. Notwith- standing the fact that the syllabus includes a considerable amount of Heat, few will deny that a previous acquaintance with that subject is desirable for rapid progress. The total number of students examined in Elementary Sound, Light, and Heat, or in the Advanced or Honours stages of Heat, was roughly 1,500. Probably not more than half these were engineering students. Yet the number sitting for examination in Steam was more than 2,000. Allow here for the students who have obtained some knowledge of the fundamental subject by attendance at a secondary school, and that still leaves at least half the examinees with an unsatisfactory foundation.' Again, by far the most popular subject in Physics is Electricity and Magnetism. No real pro- gress can be made in this subject without some knowledge of Mathematics, Theoretical Mechanics, and Chemistry ; no other subject requires such clear conceptions of energy in order that accurate notions may be developed. Thus : 2 " One of the most serious mistakes in the Science teaching that is generally made is the choice of subject. That most commonly taken is Electricity and Magnetism, which is naturally very unsuitable for students with no previous knowledge of Science; The teacher, finding himself hampered by the fact that his students know nothing of the fundamental principles of Elementary Physics and Chemistry, tends to fall back on generalities ; his teaching 1 This is, of course, wholly apart from the fact that both types of student are found in the same class. 2 Board of Education General Reports on Higher Education for 1902, p. 33. DIFFICULTIES AND SHORTCOMINGS 8 1 becomes inexact, and the giving of information of a more or less scientific character does duty for Science teaching." Twenty years ago there might have been some justification for an elementary descriptive treatment of Magnetism and Electricity. Little or nothing was then known of the electro-magnetic field, which concerned comparatively elementary students. But progress has been enormous, and dynamical concep- tions have permeated the whole subject. The standard of the examinations has increased with the spread of facilities for instruction and the multiplication of text-books ; and to-day no student who aims at exact knowledge can afford to regard it as an independent subject. The figures on page 78 are not without significance. The unsuitability of choice is not only a common result of taking up too few subjects, but occurs also when the student has filled up his time pretty fully. The student with too narrow a training has his labours considerably increased, and is bound to suffer from want of exactness and definition in his. ideas. On the other hand, too wide a curriculum leads to superficiality, and, occasionally, to mental and physical breakdown. How much an evening student can accomplish in any session depends upon previous education, ability, and strength of purpose. How much he can do with impunity — without serious injury to health — is another matter, and one not easily estimated before it is too late. In the pro- gramme of. the Northampton Institute, Clerkenwell, (p. 55) it is stated that : " It has been assumed that an earnest student will be willing to devote three, F 82 TECHNICAL EDUCATION IN EVENING SCHOOLS or in some instances, four nights a week to study during the winter months." For the general run of students three nights a week may be regarded as a maximum, and if satis- factory progress is to be made, the greatest care is needed in organising the curriculum. There must be rational grouping and order of arrangement of subjects ; the preliminary training of the students should be known exactly, in order to prevent the teacher groping in the dark ; the actual work on which the student is engaged in the daytime should be kept in view, and account should be taken of his prospective career. It is not intended to imply that these abuses exist everywhere — that there is no active control of the curriculum. There are indeed numerous instances in which heads of technical schools exercise a beneficent influence, and map out each student's work with admirable care. But there are hundreds of places in the country where there are no head- masters, and many others where the headship is nominal. In these cases each teacher is a "law unto himself." There is no co-operation between teachers, still less is there correlation of subjects. Every subject stands on its own basis. There is no guarantee of adequate preparation, no rational order and grouping, and nothing but an attenuated, ghostly caricature of a curriculum. For example: "Even in the same town and under the same Committee, one finds odd classes taken by inde- pendent teachers, who are only responsible individu- ally to the Committee. There is no one to advise students what course to take, and indeed, the subjects DIFFICULTIES AND SHORTCOMINGS 83 in which instruction is given depend on the teachers locally available. To this absence of direct control is due rivalry between classes in subjects which should appeal to similar types of students, and even the instinct of self-preservation does not prevent two or three classes in different subjects, each of which should be attended by the same students, being held at the same hour on the same evening. The distribution of classes amongst several schools in the same town is frequently due to want of adequate control and rival interests. " Such distribution of classes leads to duplication of apparatus and waste of money ; e.g., a piece of apparatus is procured for illustration of Physiography; it is equally useful for Mechanics, or Building Con- struction, or Applied Mechanics, but these classes are in different buildings, under independent teachers, so each must have a similar piece of apparatus. "As an example of lack of organisation, it may be mentioned that in one town there are eighteen classes in various subjects held at six different schools, and though in the centre of the iron industry, Metallurgy is not one- of the subjects. The extreme distance between any two of the schools is half- an -hour's walk. Classes in Practi- cal Mathematics, Building Construction, Applied Mechanics, and Steam are held at approximately the same hour on the same evening; the most central and comfortable school is only used for three subjects ; though there is a good chemical laboratory there, and suitable rooms for Art instruc- tion, the former subject is taught elsewhere in a laboratory cut out of half a chapel, and the latter 84 TECHNICAL EDUCATION IN EVENING SCHOOLS in a basement room, used in the daytime for Manual Instruction." 1 This is a picture more or less true for scores of places. They are not schools, but mere segrega- tions of classes, lacking in unity of aim and design, in economy of money, time, and effort, bringing technical education into disrepute, permitting the growth of vested interests, and constituting a serious stumbling-block in the path of progress. 1 Board of Education Report, 1901, pp. 28, 29. CHAPTER IV TENDENCIES IN EVENING TECHNICAL INSTRUCTION If any justification is required in support of the criticisms in the last chapter, it is to be found in tendencies to their removal which are exhibited to a greater or less extent by all the more important Technical Schools. It will be convenient to describe these under the titles : Admission Standard and Age ; Adaptation of the Instruction to the Special Requirements of Industry ; and Organised Courses of Instruction. A. Admission Standard and Age. The evil which results from inadequate prepara- tion is being grappled with in one of two ways. Either the student is referred definitely to the Continuation School, unless he can show that he possesses the necessary qualifications, or preliminary courses are held in the Technical School itself. The following examples show how in one or another of these ways an effort is being made to secure more satisfactory material. At St. Helens, a compulsory preliminary course has been in operation for some years, and though the innovation was accompanied by a reduction in the number of new students enrolled, it has been 85 86 TECHNICAL EDUCATION IN EVENING SCHOOLS amply justified by increased efficiency. The subjects are Mathematics, Geometry, Elementary Science, and English. Rochdale has introduced a similar obligatory course in Mathematics, English, Drawing, Physics, and Chemistry. The Blackburn Technical School held an entrance examination in September, 1904, which is com- pulsory for all those who do not hold scholarships from the higher division of the Continuation Schools. Candidates for admission are examined in English, Arithmetic, Mensuration, Algebra, and Geometrical Drawing. Stockport provides a preliminary course in Arith- metic, Freehand and Geometrical Drawing, and Elementary Science, and students are only excused if they can pass an entrance examination in these subjects. At Liverpool, students are recommended to join the branch preparatory classes or the Continuation Schools before proceeding to the Technical School. Students at Huddersfield are advised to take a course comprising Freehand and Model Drawing, Arithmetic and Mensuration, and Practical Geometry; at Derby the subjects are Mathematics, Machine Drawing, and Geometry. Swindon suggests a preliminary course in Practical Mathematics, Practical Geometry, and Practical Mechanics. Bradford has arranged a preliminary course for Engineering students in Mathematics, Geometry, and Drawing (with workshop practice if desired). West Ham provides several courses. Thus EVENING TECHNICAL INSTRUCTION 87 students engaged in Mechanical and Civil Engineer- ing, Naval Architecture, Foundry Work, and Building, are recommended to do Preliminary Practical Mathematics and Technical Drawing; for those engaged in Electrical Engineering and Applied Chemistry, a class in Preliminary Physics is suggested in addition. The standard of admission to the Manchester Municipal School of Technology is the Seventh of the Elementary School. In some cases where special preparatory knowledge is required, students must show that they are able to follow the instruction. At Preston, students are recommended to attend the Continuation School unless they have a sound knowledge of the three R's. In certain subjects at West Hartlepool, students are required to show that they possess the special knowledge which is necessary to enable them to follow the work, while Rutherford College, New- castle-on-Tyne, follows the old plan of specifying certain requirements in connection with each subject of instruction. No definite standard appears to be set up at Bristol. The Continuation School Scheme was described in Chapter II. It may be noted that while there is considerable diversity of opinion as to what constitutes a complete preliminary course for technical students, there is agreement on certain essentials. Thus the nine cases given above, in which the subjects are specified, include Arithmetic, Mensuration, Mathematics, and some form of Drawing. Physics, Chemistry, or 88 TECHNICAL EDUCATION IN EVENING SCHOOLS Elementary Science only occur in four schemes. English would probably be an invariable constituent of courses in Continuation Schools, and appears in three of the courses mentioned above, which are held in Technical Schools. A general discussion of essentials has been given in Chapter II. Comment has already been made upon the variability of age in evening technical classes. The lower limit imposed by the Board of Education, provided the student has left school, is twelve. While at present there is no uniformity in the regulations of the schools on this point, there is an indication of unwillingness to conform to the minimum. At Birmingham, students must be thirteen ; at Brighton, fifteen ; at Sheffield, Bristol, and Bradford, sixteen. In the latter place, an exception is made in favour of students who have passed through the preparatory district textile classes. There can be no doubt that but little serious technical instruction can be given to students under sixteen years of age. B. Tendencies towards Adaptation to Industrial Requirements. Until quite recently classes throughout the country have been conducted in accordance with the syllabuses of the central examining bodies. The growing specialisation of industry and the development of new manufactures have rendered new subjects necessary, and where these have not been introduced, the gap between the classes and the needs of neighbouring industries has .become EVENING TECHNICAL INSTRUCTION 89 Avider. In other cases the additions to syllabuses issued by central bodies (e.g., Building Construction) have been met by special classes in which instruction has been given to meet new requirements. Some of the innovations may be briefly noticed. At University College, Sheffield, there is a course on Machine Tool Work, which deals with those matters which a man may spend years in the shops without learning. Students are not admitted unless they have (a) been in the works for at least three years, and have been engaged in working machine tools during a portion of that time, or can pass an examination in vice - work and the simple manipulations of machine tools; (b) have attended science classes for at least one year previously and obtained a certificate in Machine Drawing, or can show that they possess equivalent knowledge. The syllabus is as follows : The cutting of spur, bevel, worm, and other kinds of wheels in the milling or planing machine. The making of formed cutters for wheels and twist drills. Making of forming tools for lathe work, or work of an irregular shape. The making of universal and independent chucks, drill chucks, Morse taper drill sockets, lathe arbors. The making of spiral, angular, and T-slot cutters, end mills, counterbores, twist drill cutters, twist drills, parallel and taper reamers. Grinding twist drills, spiral, angular, and T-slot cutters, reamers, hard steel mandrels, arbors, spindles, etc. go TECHNICAL EDUCATION IN EVENING SCHOOLS The making of jigs for drilling, milling, and grinding machines for repetition work.

Objection may be taken to these syllabuses on the ground that they aim at teaching a trade, and that therefore they are outside the scope of what the Legislature has defined as legitimate subjects for public expenditure. It has, however, already been observed that it is extremely difficult to separate the teaching of principles from the teaching of practice, and in the eyes of some people, extremely undesirable also. And it is, moreover, quite im- possible in many cases to judge whether the limitations are exceeded from a study of the syllabus. G 98 TECHNICAL EDUCATION IN EVENING SCHOOLS The question is determined entirely by the method of treatment in class, and the syllabuses permit of a thoroughly scientific method of presentation, while they deal with subjects of the highest importance. No one can read current engineering literature with- out being impressed by the superiority of American methods. American machine tools have had an enormous effect in reducing the cost of production, and have practically revolutionised some branches of industry, of which watch- and clock-making may be cited as an example. The information contained in the above syllabuses should be part and parcel of a shop foreman's equip- ment. At the same time, the number of really qualified men of this type available is small. Thus, in a paper read at a conference of science teachers at University College, Sheffield, on i ith January, 1900, Professor Ripper said : 1 "It is clear from what has already been said that we need the means of securing a steady supply of skilled machinists and toolmakers with a competent knowledge of up-to-date methods of turning work out, and of the best types of machine tools — men, in fact, who are competent to become, in course of time, leading men and works' foremen. " There are, of course, works' foremen in England second to none in the world, but everyone knows, who has any knowledge of works, that such men are singularly scarce, and when a vacancy occurs, ex- tremely difficult to replace. These men are the brain of the workshop, and upon their skill depends 1 Nature, 8th February, 1900. EVENING TECHNICAL INSTRUCTION 99 very much of the true success of any manufacturing concern. Almost any man in the works could be more easily replaced than the skilled works' foreman." A reasonable conclusion would be that there is also a dearth of teachers capable of giving the requisite instruction. Another interesting course is that on Foundry Practice at the West Ham Technical School. The following subjects are treated of in the Lectures : Properties and mixtures of pig iron ; fuel, furnaces, refractory materials ; methods of blast production ; crucibles, ladles, and foundry tools ; green sand, dry sand, and loam, their preparation and moulding in them ; drying stoves ; malleable cast iron ; chill castings ; case hardening ; casting on to other metals ; special methods of casting ; machine moulding; cleaning and dressing castings. Brass, gun-metal, and other common alloys, their compositions and methods of melting and casting in them. Methods of costing work. The freedom to draw up schemes and time-tables conferred on local authorities by the Board of Education, 1 together with the readiness of the City and Guilds of London Institute to modify their syllabuses as occasion may require, 2 will probably lead to an increase in the amount of such instruction, 1 Regulations for Evening Schools, 1904, p. 3 et seq. 2 Report of City and Guilds of London Institute, 1902. 100 TECHNICAL EDUCATION IN EVENING SCHOOLS but the provision of competent teachers who have sufficient scientific knowledge to treat the subjects from a proper standpoint will be a serious obstacle. 1 Of considerable interest, too, is the syllabus in Sanitary. Engineering at the Manchester School of Technology, which includes matter generally taught under the separate heads of Building Construction and Hygiene. The enormous growth of large in- dustrial centres has created the need for numbers of Sanitary and Building Inspectors, etc., in order that the health of the community may not suffer through carelessness or wilful negligence. . One of the most serious defects in the instruction of engineering and building students is the lack of attention to the nature and properties of materials. At the Birmingham Municipal Technical School there is* an advanced course suited to the needs of Civil and Mechanical Engineers and Architects which to some extent supplies this deficiency. A good deal of it might be described as descriptive engineering. The syllabus is as follows : Part i. Ironwork — The manufacture of cast iron, wrought iron, and steel ; description of the plant .used in modern iron and steel works ; the different kinds and qualities of cast iron, wrought iron, and steel; the commercial forms of iron and steel ; pattern- making and moulding; iron and steel casting; the mechanical properties of cast iron, wrought iron, and steel, and the methods of testing ; the practical value 1 See also syllabuses of special trade classes held at the Birmingham Municipal Technical School, the Northampton Institute, Clerkenwell, and other institutions. EVENING TECHNICAL INSTRUCTION IOI of various metalloids in cast iron and steel ; the use of iron and steel in engineering structures and machinery ; the manufacture and erection of struc- tural ironwork. Other Metals and Alloys — Their strength and principal uses in engineering. Modern Machine Tools — Description of modern machine tools and labour-saving appliances ; general arrangement of engineering works. PART 2. Earthwork — Stability of earth ; effect of water on stability ; cuttings, embankments, and dams ; clay puddle, its preparation and use ; foundations for buildings, bridges, and machinery ; methods of laying submerged foundations ; sinking shafts ; tunnelling ; dredging ; description of the plant used for earthwork operations. Masonry — Strength and properties of various stones ; different classes of masonry ; the selection and preparation of stone for different kinds of engineering work. Brick, Cement, and Concrete — Their manufacture, properties, strength, methods of testing, and use in engineering work. Timberwork — The principal kinds of timber and their use in engineering; strength of timber; preservation of timber. The strength and properties of the materials will be demonstrated in the Engineering Laboratory. The introduction of Mechanics into the Board of Education Syllabuses in Building Construction has been met in a number of instances by special courses of instruction in graphic statics. An arrangement of this sort has been made at Derby, Birmingham, Manchester, Brighton, Darlington, etc. At Salford there is a special course in Builders' 102 TECHNICAL EDUCATION IN EVENING SCHOOLS Mechanics. In regard to the arrangement of classes in Chemistry and Physics with reference to their applications to particular trades, the most notable examples are in connection with Plumbing. A considerable number of Technical Schools now provide special classes for this trade, in which an elementary knowledge of Physical Science is of the greatest importance. Examples of special classes for Engineering and other industries are seldom met with. At the same time large schools, such as those at Manchester and Bradford, hold classes in Physics — covering the whole ground of the subject — which are specially recommended as forming a necessary basis for advanced technical studies. An attempt has been made in the larger institutions to meet the particular needs of students by treating highly specialised branches separately, and often in short courses. Thus, Applied Mechanics may be treated in sections, each dealing with a particular part of the subject. The most remarkable example of this method is probably to be found at the Northampton Institute, Clerkenwell, where a limited number of teachers give instruction in short " unit " courses, which apparently can be grouped to suit any need that has arisen, or is likely to arise. Finally, the following list 1 of subjects, bearing upon the industries considered, in which grants were claimed from the Board of Education in 1902-3, will indicate the activity which is being displayed throughout the country in meeting the need which has been created by industrial specialisation. 1 Report of the Board of Education for the year 1903-4. EVENING TECHNICAL INSTRUCTION 103 Plumbing. Bricklaying and Masonry. Staircasing and Handrailing. Surveyors' Quantities. Builders' Quantities. Painters' and Decorators' Work. Chemistry for Builders. Fitters' and Turners' Work. Pattern Making. Cycle Construction. Marine Engineering. Mine Surveying. Metal Plate Work. Sanitary Engineering. Carpentry and Joinery. Carriage Building. Iron and Steel Manufacture. Assaying and Ore Dressing. Boiler Making. Boiler Testing. Some of these are from the Programme of the City and Guilds of London Institute, but many are special local syllabuses drawn up to meet local needs. The list does not include the usual science subjects of the Board of Education. C. Organised Courses of Instruction. Though for a number of years the larger Technical Schools have done much in their Prospectuses, or through the teachers, to encourage students to attend such classes as will secure a more or less 104 TECHNICAL EDUCATION IN EVENING SCHOOLS rational order and grouping of subjects, the tendency has been more marked and widespread in recent years. Most Technical Schools of any note, have drawn up tables showing the order and grouping of subjects for particular trades, but while in all cases students are strongly advised to follow the systematic courses of instruction, only three have, so far as the writer is aware, made such courses compulsory. As a general rule, the plan has been to take subjects from the Board of Education Directory and the Programme of the City and Guilds of London Institute, and to weld these into trade groups ; but in a few cases special courses of Lectures and Practical Work have been instituted in subjects which none of the Central Examining Bodies have as yet recognised by the provision of an annual test. In discussing the courses of instruction, it will be convenient to consider them under the titles of the trades, rather than of the schools. This will be consistent with the attitude adopted throughout this work, in which it is regarded as essential that the instruction and organisation should be based upon the industrial considerations. I. — General Mechanical Engineering Courses. The suggested duration of the courses is from three to five years. In only three cases are compulsory preliminary courses provided, viz. : at Stockport, St. Helens, and Rochdale. So far as the courses themselves are concerned, there is considerable difference of standard, and no small want of unanimity as to subsidiary subjects. The following table is an analysis of the courses EVENING TECHNICAL INSTRUCTION 105 given on pp. 1 10-120; the figures represent the number of courses in which one, two, or more years are devoted to each subject : Subject. One Year Two Years Three Years Four Years Five Years Six Years Mathematics, - 2 n 6 5 I Geometry, Machine Drawing, - Applied Mechanics, - Steam, - 7 1 1 2 11 5 12 14 5 13 7 3 4 4 S 2 I Theoretical Mechanics S 1 1 ' Sound, Light, & Heat, Heat, 6 2 — — Chemistry, Metallurgy, 1 i 2 1 — — The general aim is to give the students a pro- gressive course of instruction which shall culminate in the second or third stages of Machine Drawing, Applied Mechanics, and Steam. In order to attain this, various views appear to be held as to the amount of Mathematics and Geometry required to render the more technical subjects intelligible. So far as the first-named subject is concerned, it is extraordinary that any teacher should regard one year as sufficient, unless the standard on entrance is exceptionally high. Even two years, which the majority of courses entail, is little enough. A particularly interesting feature is the number of cases in which Practical Mathematics is taken, no less than nineteen out of twenty-six courses including that subject. In regard to Geometry, the difficulty seems to be to decide whether anything 106 TECHNICAL EDUCATION IN EVENING SCHOOLS beyond the elementary stage is essential. Of the eleven courses in which two years are devoted to the subject, about half are aiming at Stage I., and the rest at Stage II. For most classes of work in Machine Drawing, Stage I. of Geometry is ample, while for higher work in Applied Mechanics, the necessary graphics would fall on Stage II. No one can read intelligently an engineering text-book or journal without some knowledge of Physical Science. This statement is truer every day, and it is of interest to inquire what notice has been taken of this point in arranging the curricula under consideration. Only six courses provide instruction in Sound, Light, and Heat, and two in Advanced Heat. The introduction of Heat has doubtless been delayed to a considerable extent by its association in the elementary stage with Sound and Light — subjects which have but a small bearing upon the work of an engineer, however important they may be as part of a liberal education. Physics cover . a wide area, and the division into Sound, Light, and Heat, and Electricity and Magnetism, is almost universal. At the same time, there is no inherent reason why Heat should not be taught separately. One of the consequences, however, is that out of twenty-four courses in which Steam is taught, twelve 1 make no provision for instruction in Heat. Of course, in most cases, the teacher of Steam includes a certain amount of Heat in his lectures. How far this may be sufficient 1 Elementary Science or Physics is part of Preliminary Courses at Rochdale, St. Helens, and Stockport. Also Practical Class in Steam at Salford is really Practical Heat. EVENING TECHNICAL INSTRUCTION to; depends largely upon the individual, and in any case he would probably prefer students with a satisfactory preliminary training. The applications of Chemistry to Engineering are now increasing, and the desirability of students having some knowledge of Metallurgy has occasionally been emphasised. Three schools insist on Elementary Science (Physics and Chemistry) in the preliminary course, but beyond that only three courses contain Chemistry, and two of these add Metallurgy. Birmingham has a course on the Materials of Engineering and Processes of Con- struction, which includes the essentials of Metallurgy, Nature of Building Materials, and some Applied Mechanics. To those whose duty it is to follow closely improvements in Materials, this lack of instruction in Chemistry cannot fail to be a serious loss. The fact that many classes, especially in large towns, contain a fair proportion of students who have passed through secondary schools is not here lost sight of. But in the absence of a definite standard of admission in these subjects, too much should not be taken for granted. Most of the courses give evidence of having been carefully thought out ; a few are not only educationally unsound, but have the misfortune of being at variance with the time-table. The latter are inserted as a warning. The majority occupy three nights a week ; a few only two nights; while several require every night in the week. Thus out of twenty-three courses, for which data have been collected, fourteen devote three IOS TECHNICAL EDUCATION IN EVENING SCHOOLS nights a week in the first year, thirteen three nights a week in the second year, and thirteen three nights a week in the third. There is thus fair agreement as to the number of nights' work a week which can be expected from the average student. A greater number of nights per week than three cannot be considered satisfactory unless due to the inclusion of Laboratory or Workshop instruction. Practical work is less fatiguing than the close mental attention required to follow lectures, and it does not as a rule increase the amount of reading required from the student. To what extent it should be introduced into Evening Technical Education will be considered in Chapter VII. Some of the courses deserve special mention. It has been said that the general aim is to lead the student through a progressive course -of instruction in the specifically engineering subjects until he reaches a standard of knowledge represented by the second stage in a three or four years' course, or the third stage, or higher, in a six years' course. This is in the main true ; but there are some points of difference. Thus the courses at Bolton appear to aim at giving the student a general grounding in the subjects which underlie Engineer- ing, rather than to aim at a higher standard in Mechanics, Steam, or Machine Drawing, as in other five year courses (cf. Newcastle). The extent of difference in providing instruction in the fundamental subjects has been already noted. West Ham follows the courses for the degree in Engineering at the University of London. In these syllabuses, subjects are grouped below the EVENING TECHNICAL INSTRUCTION 109 senior stages : thus Mechanical Engineering includes both Applied Mechanics and Steam, and Engineer- ing Drawing, Geometry and Projection. This simplifies the time-table. The senior stages are broken up, and the special courses, B D and E, are similar to those in the fifth year at Birmingham, and the fourth and fifth years at Manchester. 110 TECHNICAL EDUCATION IN EVENING SCHOOLS w W III C* 1— 1 o D 2; O U i-i u HH Q < W C/> W t—i ^ 55 < ►1 o rt o Si I 2 S z o M o o B B H j.ii ? crj COhH jg SCO j 1 I AS S 6* § .3 S if j«2" .S.S » a" ■45 .S3 9 BO fd t* 3 5 • ■_: o ■a a o jtiS 5 03 CO Hon ftp Geometry, Machine D Applied M Steam, St. •i 1 3 00 H . £ 0} X B E hematics, metry, St. ring, St. I nights— 6 3§s » aos lis V>**»)ig m •S-S £ 5 a Hill a » '.3 > a m •sil 111 S B Ml ' sags 8135 a ion? a SS-«l«co ».S a S I! ill III III EVENING TECHNICAL INSTRUCTION III OQ H u 5 T 1 ■So* ■a +a to 11 £2 '3 Jl'-ii M *a a i) ^ « boa a ■a p .S «3 -S £ wota "hB« SfiHH m t- u 3 ea o n c o u V OQ ■Sals So IfiOSohl 3 M, S-a" t« » .3 .S M q a BO u a 3 a J3 ff to •♦a OI a E *»*S oo S sis M ■a °lf 9 oUSn 5 ,2 .2 Hi** .a 3rd ? b •*= >»&S P o w M 02 be • .Sm Sill EosHecq •1 ?.

In a number of schools it has been recognised that the standard of theoretical instruction aimed at in the general courses is too high for those from whom will be chosen the minor officials. Courses of instruction have therefore been drawn up in which Mechanics and Steam, for example, are not carried beyond the elementary stage, and the standard of mathematical knowledge has been similarly restricted so as to bring it within the needs and capacity of the average shop foreman. The theoretical training required by these men must of necessity be closely associated with the ordinary operations and processes of the workshop ; practical instruction is therefore highly essential, and probably explains why the courses have so far been arranged only in connection with the larger institutions. Engineering work, after the necessary drawings have been completed, passes in order through the pattern shop, foundry, or smiths' shop, fitting and turning, or boiler shop, in the order given. These represent, broadly, the divisions for which instruction may conveniently be arranged. All courses, it will be noted, provide for the teaching of simple Mathematics and a fair amount of Geometrical Drawing, with Machine or other Drawing peculiar to the special branch of the trade. Some Applied Mechanics is also generally included. A point of interest is the essentially practical char- acter of the instruction at Birmingham, which, however, does not appear to be progressive. In connection with the instruction for special branches of the trade, it may be noted that the 122 TECHNICAL EDUCATION IN EVENING SCHOOLS courses at Bolton grouped in the major division really belong here. They are worthy of close atten- tion because of the manifest attempt to give a broad basis of scientific knowledge without too much specialisation. At the same time, they do not include practical teaching in the workshop, and exception might be taken to the order of treatment on educational grounds. In smaller towns a course of instruction of this type is really what is required. Only the larger towns, as a rule, can supply a sufficient number of men capable of following the general courses. It is somewhat unfortunate, therefore, that the more ambitious schemes are universal in smaller places, where, but for the absence of workshops — and probably workshop instructors also — the more modest scheme would be desirable. This question will be further discussed in Chapter IX.

The following table shows the number of courses in which the principal subjects are prescribed, and their duration : Subject One Two Three Four Five Year Years Years Years Years Mathematics, 2 9 4 Geometry, - 3 I Machine Drawing, - 3 5 3 Applied Mechanics, 7 5 1 Steam, - 4 5 Electricity & Magnetism, 6 6 — Electric Light & Power, - 2 4 5 2 I Sound, Light, & Heat, - 3 1 — — Heat, - 1 — — Chemistry, - 4 — — — This table is an analysis of fifteen courses, as against twenty-six in Mechanical Engineering. It will be noted that there is rather more uniformity as to the number of years of study to be given to Mathematics. The conclusion to be drawn is that Mathematics is considered of more importance in Electrical than in Mechanical Engineering. It is interesting to note that ten of the fifteen courses prescribe Practical rather than Pure Mathematics. Geometry does not appear to be regarded as an essential subject, and it is somewhat surprising to find that only four courses include this subject, while eleven propose Machine Drawing. Electrical Engineering is commonly said to consist of two-thirds Mechanical Engineering and one-third 128 TECHNICAL EDUCATION IN EVENING SCHOOLS Applied Physics, and that this view is general is borne out by the attention given to Machine Drawing, Applied Mechanics, and Steam. Electricity and Magnetism is recommended for one or two years in all but three of the courses ; those three — Bradford, West Ham, and Salford — start right away with the more practical subject. The educational value of this branch of Physics, considered alone, is doubtful ; its connection with Dynamics, Heat, and Light is so close, that some general knowledge of Physics is essential. Yet only four courses provide for this. One other matter deserves notice. While in the Mechanical Engineering courses only three out of twenty-six include Chemistry, in the younger in- dustry four out of fifteen contain it. In which industry is a knowledge of Chemistry in its relation to the property of materials of greater importance, and in any case would the above figures express the relative importance? Electro-metallurgy is not taken into account, as for it special courses are provided. IV. — Minor Electrical Engineering Courses. The only Minor Electrical Industry that need be mentioned is Electrical Wiring and Fitting. Three courses are given, and there is a general similarity as to grouping and order of subjects. Some knowledge of Elementary Physics and Chemistry, similar to that usually given to plumbers, might be thought desirable.

The recommendation in some of the General Courses to attend the City and Guilds subject bearing on the student's own branch of the trade is in most cases considered a sufficient concession to specialisation. A few schools have, however, drawn up special courses, in which, while a general know- ledge of the principles underlying the whole trade are kept in view, the curriculum aims at giving the student the highest possible knowledge of his own particular division. The two courses in Carpentry and Joinery call for little comment. They are very similar, the extra year required for the Salford course being balanced by the Compulsory Preliminary Course at St. Helens. The courses in Sanitary Science contain no par- ticular point to which attention need be drawn, unless it is the tendency to over-weight them in the first year. The courses in Plumbing possess some points of interest. It is not quite clear, for example, why Theoretical Mechanics is necessary for this trade, especially as Solids is chosen. The Fluids Section would be quite appropriate. However, in all these cases, as will be clear later, regard must be had to the organisation of the school, and if the exact subject required to fit any particular trade cannot be arranged for, the nearest one must be substituted. At St Helens, Practical Mathematics and Theoretical Mechanics are taken together, and are common to all the courses. In most places it is customary to leave instruction 143 TECHNICAL EDUCATION IN EVENING SCHOOLS in Elementary Physics and Chemistry to the teacher of Plumbing. The small amount of instruction that can be given in these subjects under the circum- stances is supplemented by additional classes in the courses at Preston, Manchester, and Bristol. The second year's course at Manchester is rather heavy ; if Mechanics and Physics replaced workshop in- struction, a better balance would be obtained. The Bristol course is remarkable as including Physiology and excluding Physics. There is a greater desire manifested in these Plumbing courses to include the Physical Science underlying the practice, than in the courses for any handicraft that have yet been considered.

Of the four courses given on page 151, those of St. Helens and Longton deal with the subject purely from the chemical side. They provide a fairly satisfactory course of study for those engaged in Metallurgical Laboratories. The Longton course insists on a fairly extensive knowledge of Inorganic Chemistry, but ignores any lack of Mathematical knowledge. On the other hand, the St. Helens course does not pursue Chemistry further than the Elementary stage, but involves two years at Practical Mathematics. They are alike in failing to regard Physics as essential, and in making no provision for instruction in it. The amount of knowledge of this subject required for the daily operations of the Metallurgical Chemist is probably not great, but modern progress cannot be followed without a good grasp of the fundamental principles of Heat and Electricity. The Manchester course treats the whole subject more from the point of view of the Works Manager than from that of the Chemist. The only points which invite comment are the single year devoted to Physics and the three years' course in Mineralogy. The Swansea course recognises the importance of both Chemistry and Engineering, cuts down the essentials of Physics to one year at Electricity and Magnetism, and apparently regards Mathematics as unnecessary.

They require that on not less than two nor more than three evenings per week, not less than two nor more than four subjects be taken in any one year. The Junior Courses are intended for students between fourteen and sixteen years of age ; the Senior for those over sixteen. The scheme is intended to be suggestive rather than definite, and as will be indicated later, in some cases the elasticity destroys the benefit which it is hoped to reap from prescribed curricula. One of the most satisfactory features is the insistence upon an adequate preliminary training ; in no case is an applied subject compulsory in the Junior Course. The sentiment that permits a student to waste his time at a subject for which, though bearing closely upon his occupation, he has had no suitable preparation, is evidently less prevalent in Yorkshire than in most other counties. There are districts where the return on public expenditure is less closely safeguarded. The Junior Schemes involve thorough preparatory training in Mathematics and Drawing. The elements of Physical Science is always an optional subject, and is probably frequently taken. The introduction of Woodwork and Metal Work is worth attention. There are always students who, while capable of a certain amount of theoretical study, have their limitations in this respect, and yet possess more than ordinary manual dexterity. Such students will probably do well to follow the workshop EVENING TECHNICAL INSTRUCTION I S3 courses offered, for though the need of skilled labour is rapidly dying out in most industries in which machinery has been introduced, the necessity for clever craftsmen here and there still exists. The elasticity of curricula, as has already been remarked, is a disadvantage. The view that it may be due to the desire to cater for special branches of the main trade is not borne out on closer inspection. A more reasonable explanation would be that the limitations due to the staff, etc., of recognised schools makes alternatives imperative, the exhibitions being tenable at one or other of some forty centres of instruction. But whatever the cause, the alternatives provide ample scope for irrational order and discontinuity to creep in. 154 TECHNICAL EDUCATION IN EVENING SCHOOLS U D O U > H O O m P w H en w O O CO w c/) O U g 2 w S5 M-| o S3 0! o M ffi j K P (f) 5 1-5 X 55 C* as O u >< 3 1* p 'Mi ■aS-a .ass S ^ s -■an 41** O » " H fc P O ?, U 2 ^—^ H rt 1— I f£ w w J tf » H to Ul w Pi i4 pq O W H a) Hi o S3 CO W CO p O U dad OHO O l-H §1 6 5* :It£ to ° o g*3 « «> _ #*3'& o 8^-8 a fc.'3« a! 1 SS31 3 o «j 8 3 llsil O ! s no •tja o & is* ™"c Si, ISIS 5. © oShS so 'C« Oh«a sg 111 _.J oo ogo Ssoa jd-a ■S2fe ■Sjl S bT •S'?5„.S Si P» « BAj DO fa If .s fe.a§s f&ai-s si §11 o o B,o £5 S So •ts S H S5 O U P?
