INTRODUCTION. PUBLICATIONS. The preparation of publications relating to the survey of the oyster bars of Mary- land has been divided between the Government and the State in accordance with the laws " authorizing the work and the natural division of the surveying operations b of the cooperating forces. The publications prepared and issued by the Government under the direction of the Superintendent of the Coast and Geodetic Survey consist of a series of charts and a technical report for each county surveyed. The charts show all legal boundaries of oyster bars within the adopted boundaries of the waters opened up for leasing with each county, and the location of all landmarks (Coast and Geodetic Survey triangulation stations) used as a foundation for the delineation of these various boundaries. The technical report gives technical and legal descriptions of all oyster-bar and other bound- aries, and descriptions of all landmarks shown on the charts, and includes the report of the representative of the Coast and Geodetic Survey in charge, of the work of that Service in cooperation with the Bureau of Fisheries and the Maryland Shell Fish Com- mission. These charts and technical reports are prepared and certified for file with the courts and the Commission, as required by the laws of the State, and contain all informa- tion necessary to make a permanent record of the work of the Commission and the Government for all future requirements of the courts, or for any resurveys that may become necessary. d The publications prepared and issued by the State under the direction of the Shell Fish Commission consist of annual reports e of all the operations of the Commission a See Appendix A for laws relating to the cooperation of the Coast and Geodetic Survey and Bureau of Fisheries with the Maryland Shell Fish Commission. b See Appendix C for a summary of the particular surveying operations w'hich constitute an "oyster survey" as now being carried on in Maryland. <■ These charts and technical reports can be obtained by application to the Superintendent of the Coast and Geodetic Survey, at Washington, D. C. The publications ready for issue are those for Anne Arundel, Somerset, Wicomico, Worcester, and Calvert counties, those for St. Marys and Charles counties are now being prepared. rf The technical records and charts for each county are published separately on account of the requirements of the oyster-culture laws of the State and the practical considerations which make it desirable to have each county "opened up" for oyster culture as soon as practicable after the comple- tion of its survey. For these reasons and the fact that these reports are each arranged for distribution and use in one county only without reference to other published records, much of the text of this publi- cation is of necessity identical with similar previous publications for other counties. e These reports can be obtained by application to the Shell Fish Commission, Annapolis, Md. They are issued annually in October, and the first and second reports are now available for distribution. II 12 Survey of Oyster Bars, Calvert County, Md. performed under the provisions of the laws of Maryland," including results of biological and economic oyster investigations, methods and results of the hydrographic survey of the boundaries of oyster bars and crab bottoms, the administrative report and financial statement of the Commission, information relating to oyster culture, methods of sur- veying and leasing of oyster lots, and much other important matter of legal and scientific value. These two sets of publications are planned and arranged to supplement each other without unnecessary duplication, and when combined they form a complete report of operations, methods, and results of the work of both the Government and State. 6 COOPERATION OF THE COAST AND GEODETIC SURVEY. The work of the Coast and Geodetic Survey, as the name of the Service indicates, includes a survey of the coasts of the United States made on a geodetic basis. This has involved the gradual construction of a great framework of interstate triangulation for use as a foundation for detail hydrographic and topographic surveys, from which there has been compiled and published a complete set of charts of the coasts of the United States, including all waters of Maryland where oysters grow. This existing triangulation, hydrography, and topography is essential as a foundation for a correct and practical survey of natural oyster bars; and it being one of the fundamental func- tions of the Coast and Geodetic Survey to furnish such data, the cooperation of the Coast and Geodetic Survey with the Bureau of Fisheries and the Maryland Shell Fish Commission is a practical and natural development of Government work leading to the conservation and increase of the supply of food. COOPERATION OF THE BUREAU OF FISHERIES. The Bureau of Fisheries has cooperated with the Coast and Geodetic Survey and the Maryland Shell Fish Commission principally as an adviser in matters relating to the biological and economic survey of oyster bars and the methods to be employed for that purpose. A steam launch, rowing boat, and certain apparatus have also been furnished. The primary function of the Bureau of Fisheries is to increase the productiveness of marine and fresh waters by such measures as may be best suited to the purpose, and the services rendered in connection with the survey of the oyster bars of Maryland are strictly in line with the fundamental law under which it acts. In certain States other than Maryland similar work has been conducted by the Bureau acting independently, the same ends being attained at greater expense to the Government. GENERAL STATEMENT OF WORK OF COAST AND GEODETIC SURVEY.'* The results obtained from the work of the Coast and Geodetic Survey in coopera- tion with the Bureau of Fisheries and the Maryland Shell Fish Commission need very a See Appendix B for an extract from the "Second Report of the Maryland Shell Fish Commission," giving a concise summary of the " Haman Oyster Culture Law." b See Appendix D of this publication for "Statistics of results of combined operations of the Gov- ernment and State." c Hon. George M. Bowers, Commissioner of Fisheries, has detailed for this service Dr. H. F Moore, Assistant, Bureau of Fisheries. <* For a detail statement of the very large amount of excellent oyster survey work of the Maryland Shell Fish Commission see the "Annual Reports of the Maryland Shell Fish Commission." Survey of Oyster Bars, Calvert County, Md. 13 little other summary than is indicated by the published "Charts of Natural Oyster Bars" and the scheme of hydrographic projections and triangulation stations shown on the county progress maps attached to each report. The triangulation has been carried on in accordance with the standard methods of the Coast and Geodetic Survey, making this work and that of the "Descriptions of Triangulation Stations" of permanent value, not only to the State of Maryland in the survey of her oyster bars, but also to the Government for any future work it may do in the regions covered by the oyster-survey operations. The boundaries of the various shellfish bottoms in relation to landmarks and the adjacent topography have been shown with all the accuracy permitted by the large- scale oyster charts published especially for that purpose. The technical and legal descriptions of the boundaries and the description of the location of landmarks havs been prepared and published in such a manner as to mini- mize the probability of future disputes in reference to their location. Stated another way and quoting from the report of the "Survey of Oyster Bars of Anne Arundel County:" The geographic positions of the permanent landmarks and signals have been determined with the usual precision of a trigonometric survey, and their locations at all points necessary to provide ample foundation for the surveying and charting operations permitted great accuracy of definition and loca- tion for the natural oyster bar and other boundaries established. At the same time, the very important element of permanency of the positions of boundaries has been secured, as the relocation of geodetic positions can always be accomplished by a competent surveyor, even though the original landmarks and monuments have been washed away, as has been the fate of hundreds of such points established by the Coast and Geodetic Survey on the shores of the Chesapeake Bay during the last sixty-five years. In fact, when the survey of the oyster bars of Maryland is completed, it is believed that it will stand the test of time and practical use as a working foundation for whatever form the oyster legislation of the future may assume, and that the doing of the work systematically and accurately, once for all, will lead finally to the development of a great natural food resource in the form of real oyster culture which will bring ample reward for all expenditures of the "oyster survey." REPORT OF THE WORK OF THE COAST AND GEODETIC SURVEY IN CAEVERT COUNTY. . INSTRUCTIONS. The following two letters, together with the laws a of the United States relating to the subject, constitute the "instructions" received by the chief of the Coast and Geodetic Survey party engaged on work in connection with the Maryland Shell Fish Commission. They are short and definite, but furnish ample authority and leeway for all legitimate development of the cooperation of the Government and the State in the survey of oyster bars. The "free hand" permitted by these orders, together with the aid and many valuable suggestions received from the officers of the Survey at Wash- ington, have proved very beneficial to the work, and are greatly appreciated. Department of Commerce and Labor, Office of the Secretary, Washington, June 2, 1906. Sir: In reply to your letter of May 28, requesting me to designate officers of the Coast and Geo- detic Survey and of the Bureau of Fisheries to cooperate with the State of Maryland in making survey of and locating the natural oyster beds, I have the honor to inform you that Mr. C. C. Yates will be designated to cooperate on the part of the Coast and Geodetic Survey as soon as Congress makes the provisions of the act effective by providing an appropriation for the purpose. Respectfully, Lawrence O. Murray, Assistant Secretary. His Excellency Hon. Edwin Warfield, Governor of Maryland, Annapolis, Md. Department of Commerce and Labor, Coast and Geodetic Survey, Washington, July 3, jgo6. Sir: Upon the receipt of these instructions you will surrender the command, accounts, etc., of the steamer Endeavor to the Hydrographic Inspector. * * * As soon as this transfer is completed you will enter upon the duties of Coast Survey representative on the Shell Fish Commission of Maryland.

Steamer Endeavor, Baltimore, Md. a For these laws see Appendix A. 14 Survey of Oyster Bars, Calvert County, Md. 15 ORGANIZATION AND EQUIPMENT. The personnel and occupation of the party of the Coast and Geodetic Survey have remained practically unchanged since the beginning of the "oyster survey " Besides the chief of party, it consists of the necessary triangulators, computers, draftsmen, and temporary employees required to carry on both the surveying operations in the field and the preparation for publication of oyster charts and technical records in the Office at Washington. The equipment for the work of the party has been ample and satisfactory. The large living and office quarters furnished the Government on the Maryland Shell Fish Commission house boat Oyster have been very convenient for the work, besides facili- tating efficient cooperation with the surveying and oyster investigation parties of the State. In addition to the accommodations on the Oyster the Coast and Geodetic Survey party has had the constant use of the large steam launch Inspector and several other boats furnished by their own Service, and the occasional use of the Bureau of Fisheries launch Canvasback a and the steamer Governor McLane b of the State fishery force. The greater part of the equipment of instruments for the operations of both the Government and State have been furnished by the Coast and Geodetic Survey and consist of all necessary theodolites, levels, sextants, drafting instruments, hydrometers, etc., required for all field and office work. CHRONOLOGICAL STATEMENT OF WORK. The field work of the Coast and Geodetic Survey in Calvert County c dates from May 2, 1908, when the house boat Oyster left Baltimore for an anchorage in the Patuxent River, inside of Solomons Island. She remained in this harbor for three months, it practically being the only suitable anchorage for the work for the entire Chesapeake Bay shore of Calvert County, as well as for the lower Patuxent River. During this period there was a great amount of windy weather and consequent rough seas, which prevented work in the open bay, and in general the triangulation foundation for the oyster survey made very slow progress. On August 4, 1 90S, the part of the work necessarily done from the mouth of the Patuxent River was completed, and the Oyster was moved about 7 miles up the river to St. Leonards Creek. On August 18, 1908, the headquarters for the field work was again changed by moving the house boat Oyster 8 miles still farther up the river to an anchorage in Battle Creek, where she remained until the completion of that part of the field work which naturally included all the Patuxent River work of Charles and St. Marys counties as well as that of Calvert County, although the results are published separately. On September 3, 1908, the house boat finally left the Patuxent River for a new anchorage in a tributary of the Potomac River, and the field work of Calvert County a By courtesy of Dr. H. F. Moore, U. S. Bureau of Fisheries. 6 By courtesy of Capt. James A. Turner, commanding. c The field work of Calvert, Charles, and St. Marys counties was so intermixed in the Patuxent River that the chronological statement of work for any one of these counties necessarily includes a considerable part of the work of the other two counties. 1 6 Survey of Oyster Bars, Calvert County, Md. was dropped from that date until July 27, 1909, when it was again taken up for a period of four days to add a few details of the triangulation required for the descriptions of stations. On December 2, 1909, it was again found necessary to obtain further triangulation details for the publication of the technical report for Calvert County, and field work was carried on for that purpose from that date to December 8, 1909. The office work connected with the "oyster survey" of Calvert County, including computations and drafting necessary for the preparation of oyster charts and technical records for publications, was continued intermittingly with the office work of other counties surveyed during same season from the beginning of field work of Calvert County to the time of the filing of the certified oyster charts and reports in the archives of the Commission and with the clerk of the circuit court of Calvert County on December 14, 1909.

Before ending this report the representative of the Coast and Geodetic Survey wishes to renew his statement of appreciation of the courteous assistance received from various Government and State officials and others interested in the oyster industry of Maryland, especially to the following: To his colleague from the Department of Commerce and Labor, Dr. H. F. Moore of the Bureau of Fisheries, whose well-known scientific knowledge of all matters relating to oysters has been of great value to the work. a These statistics only include field and office work directly performed by the party of the Coast and Geodetic Survey in connection with the oyster survey of Calvert County, and do not include the many thousands of soundings and examinations of the character of the bottom made by the engineers of the Commission, which are of considerable value to the Coast and Geodetic Survey as hydrographic records for future use in connection with the preparation of new editions of charts of the waters of Maryland. See Appendix D of this publication for "Statistics of results of combined operations of the Government and the State." Survey of Oyster Bars, Calvert County, Md. 17 To Mr. Walter J. Mitchell, chairman of the Maryland Shell Fish Commission, who, by his administrative ability in carrying out the complicated requirements of the oyster laws and by his unfailing tact, has made the cooperation of the various services engaged on the work both agreeable and effective. To Dr. Caswell Grave, secretary of the Commission, who, as editor of the Com- mission's annual report and Commissioner in charge of the biological and economic oyster investigations, has been brought into constant contact with the Government work and aided its operations in every way. To Mr. Benjamin EC. Green, treasurer of the Commission, who has looked after the equipment and commissary of the house boat in such a way as to add greatly to the comfort and convenience of the part)' of the Coast and Geodetic Survey. To Mr. Swepson Earle, hydrographic engineer to the Commission, whose knowledge of the work from former service in the Coast and Geodetic Survey has greatly facilitated his practical use of the technical data furnished by the Government. To Mr. Thomas H. Robinson, counsel to the Commission, for courteously furnishing valuable information relating to county boundaries. And to the many others connected with the Commission or who as residents in the locality where the work was being carried on have greatly assisted by furnishing impor- tant information or willing services. 20908 — 10 2 CHARTS AND MAPS. CHARTS OF NATURAL OYSTER BARS. The charts a of the natural oyster bars of Calvert Count)', published by the Coast and Geodetic Survey from results of surveys of the Government in cooperation with the Maryland Shell Fish Commission, consist of five sheets covering a portion of the waters of Chesapeake Bay and all of Patuxent River, including all oyster-producing bottoms of Calvert County. They are published on a scale of i part in 20,000 (approxi- mately 3j4 inches to a statute mile) and are constructed on polyconic projections and based on the United States standard datum of the Coast and Geodetic Survey. These charts show all oyster bars and other boundaries established by the Com- mission, and are certified for the purpose of filing in the office of the clerk of the circuit court of Calvert County and in the office of the Commission at Annapolis, as required by the oyster laws of Maryland. In addition to the oyster-bar and other boundaries, the charts show the location and name of all landmarks (U. S. Coast and Geodetic Survey triangulation stations) used in making the survey, together with the hydrography and topography b necessary to make the technical definitions and delineations of boundaries readily understandable both by the people engaged in the oyster industry and the general public who may become interested through leasing of barren bottoms for oyster culture. The names of the oyster bars are those used locally, as nearly as could be ascer- tained by the hydrographic engineer of the Commission. When there was no local name in common use, a name was selected from one of the prominent features of the vicinity. By the use of recognized names or those that would naturally suggest certain sections of water, it is believed that much confusion will be avoided in the location 'on the charts of the oyster bars, especially by those not familiar with the use of maps. The corners of the oyster bars are numbered from 1 to the total number of corners in each area under consideration. Where boundaries adjoin, making one point a corner of two or more oyster bars, these points have two or more numbers, each number corre- sponding to the bar in which the figure is located. The numbers of the corners correspond with the technical and legal descriptions of this publication under the heading "Boundaries of natural oyster bars.'' The landmarks and oyster bars have been grouped in the "Contents" of this publi- cation in accordance with the charts upon which they are shown. To find a particular oyster bar or landmark which is only known by name, consult the "Contents" and a These charts can be obtained by appl : cation to the Superintendent of the Coast and Geodetic Survey, at Washington, D. C. 6 Much of the detail of the inshore topography was obtained from the excellent map of Calvert County prepared and published by the Maryland Geological Survey under the direction of Dr. William Bullock Clark from surveys of the Maryland Geological Survey in cooperation with the U. S. Geological Survey. 18 Survey of Oyster Bars, Calvert County, Md. 19 the desired chart and general location will be indicated. To find the name of a bar or landmark which is only known by location, consult the progress map at the end of this publication for the number of the chart on which it is to be found, and then examine the known locality on the chart for the name of the bar or landmark in question. The contours on the charts showing the depth of water at mean low tide have been taken from the hydrographic sheets of former work of the Coast and Geodetic Survey. Four curves were selected as being the most convenient for taking off from the original bvdrographic sheets and the ones of greatest value to those interested in shellfish industries. The i-fathom contour (6 feet) and the 5-fathom' curve (50 feet) correspond in a general way to the inner and outer limits of all the oyster bars surveyed. The 3-fathom contour (iS-feet) furnishes the curve of about the average depth of water on the oyster bars and the 10-fathom contour (60 feet) serves in a general way to indicate the outer limits of probable oyster culture. The boundaries of the waters within the "territorial limits of the county" and the boundaries of the "waters contiguous to the county" opened up for the leasing with Calvert County are plainly indicated on. the charts. A full technical description of these boundaries is given in this publication under the heading "Boundaries of county waters." The areas in acres of the oyster bars were determined under the direction of the hydrographic engineer of the Commission by two independent planimeter measurements of the areas as delineated on the smooth projections of the Coast and Geodetic Survey. These areas are given in small figures in parentheses on the face of the chart within the boundaries of the different shellfish bottoms. The symbols used on the charts for the different kinds of boundaries, triangulation stations, contours of depth of water, etc., require no other explanation than that given in the legend and other notes on the face cf the charts. LEASING CHARTS. The leasing charts of Calvert County, like those for Anne Arundel, Somerset, Wicomico, and Worcester counties, have been prepared under the direction of 'the hydrographic engineer of the Commission. These charts are constructed on polyconic projections and are based on the United States standard datum of the Coast and Geodetic Survey. They are made on the scales of 1 part in 5,000 or 1 part in 10,000, as the needs of oyster culture may require. Anne Arundel County required 13 leasing charts; Somerset County, 12 charts; Wicomico County, 2 charts; Worcester County, 3 charts; and Calvert County 5 charts, to cover their oyster bottoms. These charts show all the oyster bars, crab bottoms, and clam beds and other boundaries established by the Commission, and also all boundaries of oyster lots leased for the purpose of oyster culture, thus making them comprehensive and valuable records of the results of the operations of the oyster-culture laws. The lots leased under the provision of the "old 5-acre law" are frequently of irregular shape, but the lots leased under the provision of the new oyster laws must be of rectangular shape by the terms of that act. For this latter purpose the leasing charts have been divided by parallels of latitude and meridians of longitude into small rectangles of 1 acre or 5 acres, as may be best suited to the area under consideration, 20 Survey of Oyster Bars, Calvert County, Md. and prospective leaseholders by the rules of the Commission are compelled to select whole rectangles as far as practicable. For reasons of the present changeable nature of the number of lots leased and the large number of charts required, the leasing charts are not likely to be published for some years, but they can be seen at any time on file at the offices of the Commission, in Annapolis. PROJECTIONS. The polyconic projections a covering Calvert County waters are 8 in number and on the scale of i part in 10,000. They were constructed by draftsmen of the Coast and Geodetic Survey, but the sextant positions which determine the location of the legal boundaries of the oyster bars as delineated by the Shell Fish Commission were plotted by the draftsman of the Commission. A copy of each of these projections, with all the plotted positions of triangulation stations, shore line, sextant positions, and boundaries of oyster bars, was made under the direction of the hydrographic engineer of the Commission by pricking through with a sharp needle the intersections of the projection lines and all other points as plotted on the original sheets. These projections (in duplicate) are the original records of all oyster-bar and other boundaries established by the Commission, one set being filed in the archives of the Coast and Geodetic Survey, at Washington, and the other set in the office of the Shell Fish Commission, at Annapolis. PROGRESS MAPS. The progress map to be found at the end of this publication is on a scale of 1 part in 100,000, and shows in outline the work accomplished by the U. S. Coast and Geodetic Survey in Calvert County and contiguous waters. It gives the scheme of all the charts and' smooth projections constructed in connection with the survey, the location and names of all triangulation stations used as a basis for the surveying work, and the "boundaries of county waters" established by the Commission for the purpose of carrying out the laws of Maryland relating to oyster culture. Besides indicating the amount of work done by the Coast and Geodetic Survey in connection with the work of the Shell Fish Commission, this progress map will be. of special value for index purposes to engineers and others searching for the particular chart or projection covering the locality of the oyster bars or landmarks that may be under consideration. The progress maps b accompanying the first and second annual reports of the Mary- land Shell Fish Commission were prepared under the direction of the hydrographic engineer of the Commission. They are on the scale of 1 part in 400,000, and show the outline of the tide-water counties of Maryland, with shaded areas to indicate the waters already covered by the operations of the oyster survey. a For the scheme of these projections see the progress map at the end of this publication. t> These maps and reports can be obtained by application to Maryland Shell Fish Commission, Annapolis, Md. BOUNDARIES OF THE COUNTY WATERS. WATERS WITHIN TERRITORIAL LIMITS OF COUNTY. The laws of Maryland relating to oyster culture provide that "no person shall be permitted, by lease, assignment, or in any other manner, to acquire a greater amount of land than ten acres situated within the territorial limits of any of the counties, or one hundred acres in any other place." The boundary line 6 between the waters "within the territorial limits" of Calvert County and the waters in "any other place," as established by the Shell Fish Com- mission for the purpose of carrying out the oyster laws, and delineated on the charts and the smooth projections of the Coast and Geodetic Survey, is technically described and defined as follows : Commencing at a point denned by the intersection of the mean low-water line of the western shore of Chesapeake Bay in the vicinity of Hog Point and the boundary line between Anne Arundel and Calvert counties; thence along the mean low-water line of the Chesapeake Bay shore of Calvert County across the mouth of all inlets less than ioo yards in width, around Plum Point and Cove Point, to a point defined by latitude 38 19' 09". 8 and longitude -6° 25' 2i".o situated, on Drum Point on the northern side of the entrance to Patuxent River; thence along a straight line ending at a point defined by latitude 38 ° 18' 35". 9 and longitude 76 23' 59.". 8 situated on Hog Point on the southern side of the entrance to Patuxent River, to a point defined by the intersection of this straight line and the Patuxent River channel boundary line between Calvert and St. Marys counties as laid down on "Chart No. 20, Natural Oyster Bars, Maryland;" thence up the channel of Patuxent River following the channel boundary line between Calvert and St. Marys counties and the channel boundary line between Calvert and Charles counties and the channel boundary line between Calvert and Prince Georges counties as laid down on "Charts Nos. 19 and 20, Natural Oyster Bars, Maryland;" thence continuing up the channel of Patuxent River following the channel boundary line between Calvert and Prince Georges counties to its end on the boundary line between Anne Arundel and Calvert counties, c WATERS CONTIGUOUS TO COUNTY. The oyster laws of Maryland provide that a true and accurate delineation of all natural oyster bars shall be made on copies of charts of the U. S. Coast and Geodetic Survey, "which said copies shall be filed in the office of the said Commissioners in the city of Annapolis," and "in the office of the clerks of the circuit courts for the respective counties wherein the grounds so designated may lie." « For a complete historical and legal description of the boundaries of the counties of Maryland, the valuable publication entitled "The Counties of Maryland — Their Origin, Boundaries, and Election Districts," prepared by Dr. Edward B. Mathews and published by the Maryland Geological Survey under the direction of Dr. William Bullock Clark, Superintendent, should be consulted, as the boundaries described in this publication have been established and technically defined for the purpose of carrying out the oyster laws of the State, and may or may not be correct for other purposes.

Coast and Geodetic Survey. 21 22 Survey of Oyster Bars, Calvert County, Md. , For the purpose of carrying out the latter part of this section of the law and for the purpose of establishing the limits of the oyster-culture area to be opened up for leasing with each county surveyed, it is necessary for the Shell Fish Commission to establish a boundary line between the waters contiguous to but not within the terri- torial limits of each county and the waters contiguous to but not within the territorial limits of adjacent counties. This boundary line has been delineated on the "Charts of Natural Oyster Bars," published by the Coast and Geodetic Survey, and is technically described and defined as follows : Commencing at a point defined by the intersection of the mean low-water line of the western shore of Chesapeake Bay in the vicinity of Hog Point and the boundary line between Anne Arundel and Calvert counties; thence in a straight line along the Chesapeake Bay boundary between Anne Arundel and Calvert counties as laid down on "Charts Nos. 4 and 16, Natural Oyster Bars, Maryland," to a point defined by latitude 38 42' 33" .4 and longitude 76 27' 40". o situated about 3fs miles east of Hog Point; thence in a straight line along the Chesapeake Bay boundary between Calvert and Talbot counties and Calvert and Dorchester counties as laid down on "Charts Nos. 16, 17, and 18, Natural Oyster Bars, Maryland," to a point defined by latitude 38 30' oo".o and longitude 76 25' 3o".o situated about 4^3 miles east of Governors Run; thence in a straight line along the Chesapeake Bay boundary between Calvert and Dorchester counties as laid down on "Charts Nos. 17, 18, and 20, Natural Oyster Bars, Maryland," to a point defined by latitude 38° 23' 10". 3 and longitude 76 20' 00". o situated about 2?s miles east of Cove Point Light; thence in a straight line along the Chesapeake Bay boundary between Calvert and Dorchester counties as laid down on "Charts Nos. 18 and 20, Natural Oyster Bars, Maryland," to a point defined by latitude 38 19' 37". 7 and longitude 76° 19' ig".o situated about 5^4 miles southeast of Cove Point Light and about 5^ miles east by north of Drum Point Light; thence along the Chesapeake Bay boundary between Calvert and St. Marys counties as laid down on "Chart No. 20, Natural Oyster Bars, Maryland," to a point defined by the intersection of this boundary and a straight line between a point situated on Hog Point on the southern side of the entrance to Patuxent River defined by latitude 38 ° 18' 35". 9 and longitude 76° 23' 59". 8 and a point situated on Drum Point on the northern side of the entrance to Patuxent River defined by latitude 38 19' 09". 8 and longitude 76 25' 2i".o; thence in a straight line to a point at the end defined by latitude 38 19' 09". 8 and longitude 76 25' 21". o situated on Drum Point on the northern side of the entrance to Patuxent River.

The oyster laws of Maryland authorizing the survey to be made by the Shell Fish Commission provide for "an accurate report of said survey, setting forth such a descrip- tion of landmarks as may be necessary to enable the said board, or their successors, to find and ascertain the boundary lines of said natural oyster beds, bars, and rocks, as shown by delineation on the maps and charts." The law of the United States author- izing the cooperation of the Department of Commerce and Labor in the survey of natural oyster bars of Maryland provides for the erection of "such structures as may be necessary to mark the points of triangulation, so that the same may be used for such future work of the Coast and Geodetic Survey as the said Bureau may be hereafter required to perform in prosecuting the Government coast survey of the navigable waters of the United States located within the State of Maryland." Under the provisions of the sections of the laws stated above, the markings and descriptions of landmarks must be sufficient for the present and future needs of both the Government and the State. With this end in view, considerable work has been expended in erecting permanent monuments at the triangulation stations and in the proper description' of their location. An effort has been made to arrange the descriptions of location and character of landmarks in a uniform and logical manner. The descriptions start with the assump- tion that the individual seeking a landmark has only an indefinite idea of its location. They gradually proceed from description of the general locality of a landmark to the descriptions of its immediate surroundings. This is followed by specific details of the character of the center and reference marks and a "round" of reference angles and distances which in themselves frequently contain enough information to furnish an independent and reliable location of the triangulation station. METHOD OF DESCRIBING TRIANGULATION STATIONS. The separate descriptions oj triangulation stations should not he used without reading the following explanation oj the method oj describing the triangulation stations, as it con- tains certain details that are common to all the landmarks described in this publication and which are omitted in the separate descriptions as being need/ess repetitions. Name. — The title at the top of each separate description is the name by which the landmark or triangulation station is known and designated in all work and pub- lished oyster records or oyster charts of both the Government and State. The selec- tion of the name is usually left to the triangulator establishing the station, and it may or may not have geographic or other significance in reference to the locality. General locality. — Under this heading is given the general locality of the landmark in reference to well-known and prominent natural or artificial features, such as the 23 24 Survey of Oyster Bars, Calvert County, Md. nearest body of water, town, river, steamer wharf, well-defined point of land, church, or any other feature that is likely to remain both permanent and prominent. This heading also covers a reference to the published chart or map which shows the location of the station most clearly. Nearly all the triangulation stations described in this publication are plainly indicated by name and a triangulation symbol on .the published charts of oyster bars of Maryland. In this case they are referred to by serial number only, the words "charts of oyster bars of Maryland" being omitted to avoid needless repetition. These published oyster charts are on the large scale of i part in 20,000 (approximately 3^ inches to a statute mile) and show the location of the trian- gulation stations so clearly that in many cases the written descriptions will not be required to find them. Immediate locality. — Under this heading is given the description of the "observed station" in reference to its immediate surroundings. This is supposed to include a statement of the station's estimated elevation above high water or some other well- defined level of the locality, such as a road or house; the character of the ground on which it" is located, such as marsh land, sand beach, cultivated field, or meadow; esti- mated bearings in points of the compass and estimated distances in yards from {not to) easily recognized features, such as extreme end of point, edge of bluff, bank of creek, line of telephone poles, shore line, barn, house, fence, ditch, trees, or any other definite detail, such as being on range with the tangent of an island and a church; and so forth. When a standard monument has been established near the station as a "reference station," this heading also covers a statement of the true bearing of the monument in degrees and minutes and its measured distance in meters, as it is the first object that is likely to catch the eye when the immediate vicinity of the desired station is reached and might be mistaken for the center mark of the "observed station" unless special attention is called to it. The distinction between the "observed station" and "reference station" should be carefully noted by anyone making use of the description of stations for any future surveying operations. The "observed station" is located at the particular triangulation point covered by the description of stations, and is the one whose geographic position is first computed, as it is the point which was "occupied" and "observed on" for horizontal angles. How- ever, in spite of the primary importance of the location of the "observed station," it will be noted from the description of stations that frequently it is not marked as well as the "reference station," and in many instances has only a pine stub to indicate its position. This is the case for the reason that the necessity of intervisibility of land- marks usually made it compulsory to locate "observed stations" on edges of banks and ends of points of land, which in the tide-water section of Maryland generally means they will be washed away in a short period of years. The past experience of the Coast and Geodetic Survey in this region has shown the great need of "reference stations," if the frequent reestablishment of a new framework of triangulation is to be avoided. The chief reason and need for the establishment of the "reference station," or secondary station, as it might be well named, is explained in the preceding paragraph, but in several instances other reasons, such as the location of the "observed station" on an unstable sand dune, in a cultivated field, in front of a residence, or other places Survey of ( hster Bars, Calvert Comity, Md. 25 objection;.!)'.!.' lo the landowner, have led to establishment of "reference stations." The location of the "reference station" in relation to the "observed station" is fixed for plotting on charts or for computation of its geographic position by checked measure- ments of its distances and azimuth from the "observed station."" Marks. — Under this heading is given a description of the character of the permanent monuments or other marks of the location of the "observed station," and of the "refer- ence station" where one has been established. All the marks designated in the descriptions as "the center point of triangle on standard cement monument" are exactly alikt. These monuments are made of cement, sand, and gravel, and are 2 feet long and 8 inches square at top and bottom. Their tops are all marked with the same brass mold and show a center hole surrounded by a triangle, with the letters "M. S. F. C." arranged around the vertex and the letters "U. S. C. S." underneath the base of the triangle. The center hole is always in the center of the top of the monument by construction, and if this is found to have been broken off without disturbing the bottom the center of its square section can be used as the location of the station. All the "standard cement monuments," whether used for marking the "observed station" or "reference station," have been planted upright in exactly the same manner, with their tops projecting 3 or 4 inches above the surface of the ground, unless otherwise stated. Therefore, as the above facts in reference to the "standard cement monuments" are a constant element in all cases, the repetition of these facts in the description of stations is made needless by this one statement. References. — Under this heading are given the "rounds" of directions and distances to all objects that might be useful in locating the stations when the surface marks can not be found. It is also contemplated that for general purposes of topography, hydrog- raphy, or location of boundaries of oyster bars these references will be sufficient in many cases to relocate the position of an "observed station" or "reference station" when both of them have been destroyed. The first reference object given in the descriptions is always a triangulation station visible from the station being described, this, if possible, being a light-house, church spire, or other permanent and prominent point. Its direction is taken as being o° 00' 00", and the directions of all other objects are measured from it as an initial point, the angles being taken in a clockwise direction (left to right). The true bearing b of the initial object is always given in parenthesis alongside its name. This furnishes means for the calculation of the bearings of any of the other reference objects for the purposes of locating a station by horizontal angles or for the relocation of corner buoys of oyster-bar boundaries by the method of compass directions described in this publication under the heading of "Boundaries of oyster bars." The distances in the last column under "References" are given in three different units, which vary according to their accuracy. The "miles" are statute miles and may "Geographic coordinates (latitude and longitude) and the distance and azimuth relating to any of the "observed stations" or of the "reference stations" described in this publication can be obtained by application to the Superintendent of the Coast and Geodetic Survey, at Washington, D. C. b The mean magnetic variation for Calvert County was 5° 50' west of north in 1909 and increasing at the rate of 3' yearly. 26 Survey of Oyster Bars, Calvert County, Md, be considered only as rough estimates. The "yards" are more accurate, but must be looked on as results generally obtained by pacing or careful estimating. The "meters," however, are accurate to the degree indicated by their decimals and in every case have been measured with a steel tape. In the same manner the accuracy of the directions are indicated by the refinement of angular measure with which they are recorded. DESCRIPTIONS OF TRIANGULATION STATIONS. HOLLAND.

BOUNDARIES OF OYSTER BARS. EXPLANATION. The law of the United States authorizing the cooperation of the Department of Commerce and Labor in the survey of natural oyster bars of Maryland provides for the designation and employment by the Department of Commerce and Labor of such officers, experts, and other technically qualified persons "as may be necessary to cooperate with the Maryland State Board of Shell Fish Commissioners in making a survey of and locating the natural oyster beds, bars, and rocks in the waters within the State of Maryland." The oyster laws of Maryland provide that the Maryland Shell Fish Commissioners, with the aid of such persons as may be designated by the Government, shall proceed "to have laid out, surveyed, and designated on the said charts the natural beds and bars, and shall cause to be marked and defined as accurately as practicable the limits and boundaries of the natural beds, bars, and rocks as established by said survey, and they shall take true and accurate notes of said survey in writing, and make an accurate report of said survey, setting forth such a description of landmarks as may be necessary to enable the said board, or their successors, to find and ascertain the boundary lines of the said natural oyster beds, bars, and rocks, as shown by a delineation on the maps and charts." The oyster laws of Maryland also provide in another section that there shall "be made a true and accurate survey of the natural oyster beds, bars, and rocks * * * with reference to fixed and permanent objects on the shore, giving courses and distances, to be fully described and' set out in a written report of said survey." Under the provisions of the laws quoted above the State of Maryland, in coopera- tion with the Department of Commerce and Labor, must define the boundaries of the natural oyster bars "as accurately as practicable" and also "with reference to fixed and permanent objects on the shore, giving courses and distances." The requirement of "as accurately as practicable" is easily fulfilled by definition of the location of the cor- ners of the oyster bars by latitude and longitude. In fact, this method is probably the most satisfactory and accurate one that could be used for all purposes of legal definition or for relocation of the oyster-bar boundaries by competent engineers. Therefore the additional requirement of "giving courses and distances" is superfluous and is only fulfilled in the published definitions on account of the specific provisions of the law making it compulsory. This part of the description of boundaries has involved an immense amount of extra computations in order to prevent technical discrepancies between the latitude and longitude of a corner of an oyster bar and its distance and bearing from objects on shore of known latitude and longitude without adding anything' to the accuracy and very little to the convenience of practical use of the descriptions of the oyster-bar boundaries. 59 60 Survey of Oyster Bars, Calvert County, Md. As provided by law the boundaries of the oyster bars are all straight lines, but in the work already completed they have inclosed areas of all shapes from triangles to complicated 14-sided figures, and of all sizes from 4 acres to 7,548 acres. The sides have varied in length Irom 93 to 7,529 yards, and in some cases the corners of the bound- aries have been practically at the triangulation stations from which they are located, while in other instances they were over 13,600 yards from the landmarks most available for the purpose of fixing their position. The varied characteristics of the legal boundaries of the oyster bars indicated by the above statement, together with the complicated requirements of the law under which the survey has been made and the magnitude of the work with the conse- quent need of fixed and uniform methods, have made the problem of describing the boundaries one of considerable difficulty and great importance. The boundaries of the oyster bars of Maryland, as established by the Shell Fish Commission and delineated on the Coast and Geodetic Survey charts and projections and on the leasing charts of the Commission, are technically defined and described by a method somewhat different from that used in other oyster surveys. But it is believed that the forms finally adopted will fulfill all needs of the survey for both the present and future. METHOD OF DESCRIBING BOUNDARIES. The descriptions have been arranged in tabular form, thus avoiding many hundred repetitions of the same words by making one explanation of the tables sufficient for all oyster bars in each county. Title. — At the top of each tabular form is given the legal name of the oyster bar to be described, and the one by which it is known and designated in the published oyster records and on the oyster charts. The adopted name of the oyster bar is the one used locally, as nearly as could be ascertained by the hydrographic engineer of the Commis- sion; and when there was no local name in common use a name was selected from one of the prominent features of the vicinity that would naturally suggest the section of the waters where the oyster bar was located. Underneath the name, in parenthesis, is given the general locality of the oyster bar and the serial number of the "Maryland Oyster Chart" on which its legal boundaries are shown." First column. — This column, under the heading of "Corner of bar," gives the num- ber corresponding to the corner of the boundary as shown on the charts and to the number on the buoy marking the actual corner of the bar. The numbers of the corners have been assigned by naming the southernmost point No. 1, thence proceeding in a clockwise direction around the bar; but where a corner of one oyster bar is identical with the corner of the boundaries of one or more other oyster bars only the number of the corner of the oyster bar being described in the table is given in this column. Second and third columns. — These two columns, under the headings of "Latitude" and "Longitude," give the geographic positions of the corners. These positions have been adopted by the Commission as the primary technical definition of the location of the corners, and should be considered as final in case of a dispute arising from discrep- a These charts can be obtained by application to the Superintendent of the Coast and Geodetic Survey at Washington, D. C. Survey of Oyster Bars, Calvert County, Md. 61 ancies caused by other means of location. The latitudes and longitudes given in these columns are based on the United States standard datum of the Coast and Geodetic .Survey, and the points thus defined can be relocated from distant triangulation stations of the Survey, even though all the landmarks and buoys originally used for their location have been destroyed by natural or other causes. Fourth and fifth columns. — These two columns, under the general heading of "True bearing" and the specific headings "Forward" and "Back," give bearings measured from a true north-and-south line. The three "Forward" bearings are from the corner of the boundary designated in the first column to the triangulation stations named on the corresponding lines in the last column, and the three " Back " bearings are from these same stations in the last column to the corresponding corner of boundary in the first column. The difference in minutes of arc between the forward and back bearings shown in some cases is actual and not accidental, and is due to the fact that the com- putations took into account the spheroidal shape of the earth. Sixth column. — This column, under the heading of "Distance," gives the three computed distances in yards from the corner of the bar noted in the first column to the three triangulation stations named on the corresponding lines in the last column, and vice versa. Seventh column. — This column, under the heading of "U. S. C. & G. S. triangula- tion station,"'' gives the names of the landmarks from which were computed the cor- responding "Latitude," "Longitude," "True bearing," and "Distance" of the "Corner of the bar" designated in the first column. A full description of the location and mark- ings of these triangulation stations is given in another part of this publication under the heading of "Descriptions of triangulation stations." SURVEYING METHODS FOR RELOCATION OF BOUNDARIES. There are a number of methods that can be used in the relocation of the actual boundaries of the natural oyster bars as technically described in this publication and delineated on the published charts of the Coast and Geodetic Survey and the leasing charts of the Shell Fish Commission. The following brief descriptions of five of these more or less different methods assume a certain amount of experience and knowledge on the part of the engineer in the particu- lar kind of surveying under consideration, and are only intended as reminders of ways and means that can be used. There are two problems that are likely to present themselves to those interested in the boundaries of natural oyster bars: One, to determine whether the buovs marking the corners have been dragged or otherwise moved from their correct positions, and the other, to relocate or reestablish a buoy at the point from which it was removed. The different ways of solving these two problems partly depend upon the instruments pos- sessed by the engineer and his assistants and partly on his training and experience. « The mean magnetic variation for Calvert County was 5 50' west of north in 1909 and increasing at the rate of 3' yearly. b Geographic positions of these triangulation stations can be obtained by application to the Super- intendent of the Coast and Geodetic Survey, Washington, D. C. 62 Survey of Oyster Bars, Calvert County, Md. (i) Triangulation. — This method is the one that will give the greatest accuracy, but on account of its requiring special data and instruments, and being an operation rarely used by engineers not engaged in geodetic surveying, it is recommended only for cases in dispute that can not .be settled satisfactorily by some other method. An explanation of this class of work would be too long for a report of this sort, and those not familiar with this method are referred to the publications on the subject by the Coast and Geodetic Survey. (2) Hydrographic. — This method is the most simple and satisfactory one that can be adopted if the surveyor can obtain the use of the necessary instruments and assistants. It is the one best suited for the work of the engineers of the Commission in relocating corners of boundaries, as it gives results of the accuracy ordinarily required and is rapid in execution. Besides, it has the advantage of being available whenever three triangu- lation stations of suitable relative positions are visible from the offshore points needing relocation. Most navigators and others familiar with the use of a sextant are well acquainted with the graphic three-point method of fixing a position on water, and only a brief description of the operation will be stated. In the case where there is only one engineer having a single sextant, the three-point method can be used if the two angles determining the position of a buoy are first derived from the "Forward" bearings given in the tabular forms describing the bound- aries of the oyster bars. For example, take "Hog Point" bar, which is the first one described in this publication, and assume that "Corner No. 1" is to be examined as to its position. The angle between the two landmarks "Hog Point" and "Beach," as determined from right to left from the forward bearings from this corner is 67 35' and the angle between "Beach" and "111 2" is 17° 16'. Having these two angles,* the engineer proceeds to the buoy of doubtful location and measures the actual sextant angles between the landmarks for which the calculations were made. If the meas- ured and calculated angles do not agree the buoy is not in its correct position and the boundary corner must be relocated. This is accomplished by moving the boat about until a point is reached where the angles do agree, and this point being the desired location the buoy can be placed in its correct position. If the engineer can obtain the use of both a sextant and a three-arm protractor ("position finder"), the availability of the hydrographic method is increased, as the use of the protractor is essential in case of the washing away or destruction of one or more of the landmarks originally used in describing the boundaries. Under these circum- stances, any three landmarks of suitable relative position that are visible from the point to be located can be utilized. For example, the engineer can proceed to the buoy of doubtful position and measure the two adjacent sextant angles between the three landmarks selected. These two angles are set off on the three-arm protractor and the actual position of the buoy plotted on the chart by shifting the protractor about until the edge of each of the .three arms passes through the center of the symbols on the chart marking the position of the three landmarks selected. The center of the hub of the protractor will indicate on the chart the actual position of the buoy, and if the Survey of Oyster Bars, Calvert County, Md. 63 point thus obtained docs not coincide with the true position of the corner of the bound- ary as given on the chart the surveyor can proceed to locate the buoy correctly by reversing the operation. This is done by placing the center point of the hub of the protractor over the corner of the boundary in question and measuring on the chart the two adjacent protractor angles between the three selected landmarks. One of the angles thus obtained is set on the sextant and the boat moved about until the two landmarks are shown by the sextant to subtend the same angle obtained from the protractor. The second angle is then placed on the sextant and the; same operation gone through, and so on, first using one angle on the sextant, then the other, until a point is reached where both observed sextant angles are practically identical with the protractor angles. The point thus located is the desired one and the buoy can be placed to mark the true position of the corner of the boundary in question. If the engineer possesses two sextants and a protractor this problem is far easier of solution, as the two angles can be set off on separate sextants and the observer can quickly find the desired point where they agree with the protractor angles by using one sextant after the other without the need of resetting either. If there are two observers two sextants, and a protractor, it can be seen that the best conditions for both rapid and accurate hydrographic locations of points are attained ; in fact, this is the method by which the buoys at the corners of the boundaries were .originally placed by the hydrographic engineer to the Commission. (3) Magnetic bearings from offshore. — This method of fixing a position on water is a simple and well-known one in navigation. It is available to anyone having a boat compass, and will be of special use to the State Fishery Force in investigating cases where buoys are supposed to have been moved for illegal purposes. In the case where a buoy is supposed to have been moved from its true position the observer takes compass bearings to the three landmarks given in the last column of the tables opposite the boundary corner in question. These bearings are then corrected for the local declination, and if the results agree with the published bearings the buoy is correctly located. In the case where the buoy is not in its correct position, or has disappeared altogether, the desired point can be determined by maneuvering the vessel until the corrected bearings agree with the ones in the tabular descriptions, when the buoy can be anchored in its proper location. In the case where the landmarks for which the bearings are published have been destroyed or washed away, any landmarks whose positions are indicated on the charts can be used by getting their bearings directly from the chart by parallel rulers or a protractor and then applying them in the same manner as the ones published in the tables. (4) Magnetic bearings from shore. — This method will be of special value to engineers having an ordinary surveyor's compass. The compass can be set over the point mark- ing a "triangulation station" on shore, the name of which is given in the last column o The mean magnetic variation for Calvert County is 5 50' west of north in 1909 and increasing at the rate of 3' yearly. 6 4 Survey of Oyster Bars, Calvert County, Md. opposite the "corner" in question. The instrument is then set at the corresponding "back" bearing (corrected for local magnetic declination) given in the fifth column of the tables opposite the "corner" in question, and the direction thus determined will give one range on which the desired point must be located. The compass can then be moved to a second triangulation station and another range located in a similar manner. The intersection of these two range lines will give the desired point; but in general it should be checked by an additional range line determined from a third station. (5) Horizontal angles measured at landmarks. — This process is a modification of the triangulation method, and will be useful to engineers who have a transit and desire considerable accuracy. The instrument is placed over a " triangulation station," the name of which appears in the last column of the tabular description opposite the "corner" in question. The telescope is then pointed to the landmark indicated in the "Descriptions of landmarks" as having a direction of o° 00' 00" from the triangulation station being occupied by the transit. The tabular description of the boundaries is next examined and the "back" bearing of the questionable boundary "corner" from the landmark being occupied is taken out. The angle calculated from this "back" bearing and the bearing given in parenthesis alongside the zero landmark in the "Descriptions of landmarks" is then set off on the transit, and a range line established on which the desired point must be located. A similar process is then carried on at a second station, and so on until the position of the buoy is satisfactorily fixed. BOUNDARIES OF NATURAL OYSTER BARS. HOG POINT.

Appendix B— THE HAMAN OYSTER CULTURE LAW. [Extract from Second Report of Shell Fish Commission.] OBJECT. "The legislature in placing chapter 711 of the acts of 1906, better known as the Haman Oyster Culture Law, upon the statute books of Maryland had a twofold object in view : 1. To encourage an industry in oyster culture upon the barren bottoms beneath the tidewaters of the State. 2. To prevent the leasing of natural oyster bars for the purpose of oyster culture." " To make the leasing of barren bottoms possible and the leasing of natural bars impossible, pro- vision was made for a survey of the natural bars for the purpose of accurately locating and marking the same. It was definitely provided that no barren bottoms should be leased in any part of the State until the natural bars of that region had been surveyed, charted, and marked with buoys." Survey of Oyster Bars, Calvert County, Md. 91 Definition of a Natural Oyster Bar. natural bar not defined. "The Shell Fish Commission is instructed by section 90 of the Haman Oyster Culture Law to exer- cise its judgment liberally in favor of the natural bars when surveying, charting and buoying them, but other than this the Commission is uninstructed in this important matter. The responsibility of defining a natural bar is placed upon the Commission." DIVERSITY OF OPINION. " No definition of a natural oyster bar could be formulated by any man or body of men which would meet with the approval of all parties concerned. Oystermen, as a rule, hold that all bottoms where oysters grow or have grown naturally even though now practically barren of oysters should be considered natural bars. Other citizens of the State who are not directly interested in the oyster business, but interested in the oyster industry from the standpoint of revenue, hold, as a rule, that no bottoms should be excluded from leasing for oyster culture which, by methods known to oyster culturists, may be made to vield a greater number of oysters than they now produce." "It should be evident to everyone that neither of these definitions could be adopted by the Com- mission as a working basis for determining which of the grounds surveyed are natural oyster bars." THE GOLDSBOROUGH DEFINITION. The definition of a natural oyster bar which very nearly approaches a reasonable and satisfactory compromise between the views of the subject held by oystermen on one hand and by oyster culturists on the other is that contained in an opinion rendered by Judge Charles F. Goldsborough in the circuit court for Dorchester County in the July term, 1 881, in the case of William T. Windsor and George R. Todd v. Job T. Moore. This definition has been adopted by the Shell Fish Commission as the basis for the determination of the status of the various oyster bottoms surveyed and is as follows: What then is a natural bar or bed of oysters? It would be a palpable absurdity for the State to attempt to promote the propagation and growth of oysters and to encourage its citizens, by a grant of land, to engage in their culture, if the lands authorized to be taken up were only those upon which oys- ters do not and can not be made to grow. That there may be lands covered by water in the State where no oysters can be found, but where, if planted, they could be cultivated successfully, may be possible, but, if so, I imagine that their extent must be too limited for them to be of much practical, general advantage for the purposes of such a law as the one under discussion ; but there are thousands of acres of hard and shifting sands where oysters not only are not found, but where it would be folly to plant them; and these latter it can not be supposed that the State intended to offer to give away, for the simple reason that the State could not help knowing that nobody would have them. Upon the other hand there are large and numerous tracts where oysters of natural growth may be found in moderate numbers, but not in quantities sufficient to make it profitable to catch them, and yet where oysters may be successfully planted and propagated. In my opinion these can not be called nat- ural bars or beds of oysters, within the meaning of the Act of Assembly, and it is just such lands as these that the State meant to allow to be taken up under the provisions of the above-mentioned section of the Act. But there is still another class of lands where oysters grow naturally and in large quantities and to which the public are now and have been for many years in the habit of resorting with a view to earn- ing a livelihood by catching this natural growth, and here, I think, is the true test of the whole question. Land can not be said to be a natural oyster bar or bed merely because oysters are scattered here and there upon it, and because if planted they will readily live and thrive there; but whenever the natural growth is so thick and abundant that the public resort to it for a livelihood, it is a natural oyster bar or bed and comes within the above-quoted restriction in the law, and can not be located or appropriated by any individual. APPLICATION OF DEFINITION. Before this definition may be of use in determining, accurately and scientifically, the status of an oyster ground, its central idea, "livelihood," must be expanded into accurately determinable factors, and these factors must be combined into a practical scheme of investigating the condition of the ground under consideration. Stated briefly, a livelihood is represented by a sum oj money obtained from the sale, at a fixed price, of a certain quantity oj oysters gathered in a given time from an allotted area of ground. 92 Survey of Oyster Bars, Calvert County, Md. Knowing the value of each of these factors it becomes possible to calculate the number of oysters an oyster ground must produce per square yard in order that oystermen may secure a livelihood by working upon it. Note. — The factors into which the Commission resolved the livelihood problem, the value assigned to each factor, and the scheme devised for practical use in examining and applying the definition to oys- ter bottoms are given in outline in their Second Report under the heading of the preceding extract, and in detail in their First Report on pages 32 to 69. , Appendix C— SUMMARY OF THE PARTICULAR SURVEYING OPERATIONS WHICH CON- STITUTE AN "OYSTER SURVEY" AS NOW BEING CARRIED ON IN MARYLAND. Explanation. — A brief account of the particular surveying operations which constitute an " oyster survey" as now being carried on in Maryland will assist in the interpretation of records contained in the technical part of this report, and will be of interest to many who may not understand the necessity for the great amount of work being done or its complicated character. To those familiar with methods used in surveying and charting the characteristic features of large bodies of water there is an evident necessity for the various operations performed, especially when it is known that the boundaries of the public oyster bars and of the private lots leased for purposes of oyster culture must be surveyed and charted with the greatest practical accuracy. To others it will be sufficient to state that the actual experience gained from oyster surveys in other States has proven that in order to avoid endless dissatisfaction and litigation it is necessary to accurately locate and per- manently establish oyster boundaries as is now being done in Maryland. Triangulation survey. — Such refinement of survey work as that demanded by the conditions of an oyster survey when carried on at considerable distances offshore can only be obtained by the use of a system of triangulation as a frame work or foundation. Therefore, a triangulation survey including the permanent marking of the positions of landmarks with monuments and a record of the descriptions of their locations for future recovery is a necessary operation of a complete oyster survey. Topographic survey. — The technical records which establish the relation between the offshore oyster boundaries and triangulation landmarks are sufficient for the requirements of engineers in making resurveys, but do not supply the needs of others who are interested in the same boundaries by reason of their occupation as oystermen concerned as to the public oyster bars, or oyster culturists concerned as to the leasable bottoms. For these it is necessary to have the charts of the survey show the relation of the shore line and other topographic features to the boundaries of the public oyster bars and private oyster farms. Therefore, a topographic survey is a necessary operation of a complete oyster survey. Hydrographic survey. — In the settlement of the important question of what is, or what is not, a natural oyster bar, and in the consideration of bottoms to be selected for purposes of oyster culture, information as to the depth of water and the character of the bottom is required. Therefore, a hydro- graphic survey is a necessary operation of a' complete oyster survey. Necessary foundation for an oyster survey. — Consequently, the necessary components of a satis- factory foundation for a complete oyster survey are the three classes of survey operations technically named triangulation, topography, and hydrography, or, stated in another way, the foundation of a practical oyster survey includes the surveying operations usually followed by the Coast and Geodetic Survey leading up to the preparation and publication of nautical charts. Special surveys and investigations pertaining to oysters. — Having obtained this cartographic survey for a foundation, partly by new work and partly from records of previous work of the Government, the combined operations making up an "oyster survey" are completed by superimposing on this foundation special surveys and investigations pertaining particularly to oysters or other shell fish. The special surveys pertaining to oysters, furnish information as to the location and outline of oyster-shell bottoms, and are carried on by the sounding boat party in addition to the usual hydro- graphic work.k This operation consists of the observation and record of the character of vibration of a wire and chain apparatus which is dragged over the bottom, the vibrations or lack of vibrations indicating the presence and quantity of shells or absence of shells. a See Appendix D of this publication for "Statistics of results of combined operations of the Government and State." b See pages 104 to 123 of "First Annual Report of Maryland Shell Fish Commission." Survey of Oyster Bars, Calvert County, Md. 93 The special oyster investigations " consist of the actual determination of the kind and quantity of oysters on the bottom, and such economic and biological studies of the supply of oyster food, density of water, character of the bottom, and other important matters as affect the growth of oysters. In this work the oyster investigation stations are located and buoyed by the hydrographic party while engaged in the survey of the oyster-shell limits. They are selected with the view of obtaining char- acteristic data which can be used for the interpretation of the recorded vibrations of the chain apparatus at all other points covered by the survey. Preparation, oj results. — The actual surveying operations and oyster investigations having been completed for any one county, there still remains technical work of nearly equal magnitude to that described. 6 This work consists of the preparation of charts and technical descriptions of boundaries and landmarks for publication by the Government, the preparation of that part of the annual report of the Commission covering the special oyster surveys and investigations, the making of the leasing -harts and finished projections, and finally the filing of the oyster charts and records with the courts and the Commission, thus opening a county for oyster culture. Summary. — From the foregoing account it can be seen that a complete oyster survey properly conducted so as to answer all practical requirements of the present and permanency of results for the future is a very complicated affair, involving many lines of surveying and other scientific work, and requiring the professional services of experts in the various operations of cartographic surveying and shell-fish investigations. See pages 30 to 67 and 1 29 to 199 of "First Annual Report of Maryland ShelJ Fish Commission." 6 No mention is made here of the large amount of administrative work of the Commission, which is greatly complicated and increased by the effect of the oyster-survey operations on many thousands of people whose interests are more or less involved; or of the large amount of survey work involved in the survey and record of the boundaries of oyster lots leased from the State by private individuals for the purposes of oyster culture. 94 Survey of Oyster Bars, Calvert County, Md, Appendix D.— STATISTICS OF RESULTS OF THE COMBINED OYSTER SURVEY OPERATIONS OF THE GOVERNMENT AND STATE."
