SPECIAL REPORTS. On July 2, 1892, in response to a resolution of the United States Senate for information concerning the salmon fisheries of Alaska, a report was transmitted to the Senate (Mis. Doe. 192, Fifty-second Congress, first session) discussing the origin and development of the fisheries, statis- tics of the fisheries, present condition of the fisheries, methods and apparatus employed, the protective regulations of the fisheries, and recommendations as to further legislation in reference thereto. This report will also be found in the Bulletin of the United States Fish Com- mission for 1892. LIBRARY. The accessions to the library, which were mainly by donation and in exchange for the publications of the Commission, embraced 1,064 books, of which about one-fourth related directly to fish and fisheries, and the balance to zoology, natural history, and kindred subjects. OFFICE OF ARCHITECT AND ENGINEER. While under orders to make investigations of certain localities in Montana offering advantages for the location of a fish-cultural station, Mr. Charles E. Gorham, the architect and engineer of the Commission, died at Bozeman, Mont., November 13, 1892. For the purpose of secur- ing a competent engineer to fill the position thus made vacant, the United States Civil Service Commission held a special examination for applicants, and upon their certification Mr. Hector von Bayer was appointed thereto on March 1, 1893. The following is Mr. Von Bayer’s report, showing the work of con- struction at the different stations of the Commission during the year: Green Lake Station, Maine.—The two settling reservoirs were finished; a number of new rearing ponds were excavated; a branch box flume was laid, which taps the main supply flume, for feeding the new ponds, and a system of outdoor rearing- troughs and tubs; new drains from the ponds and troughs were laid; a number of buoys were placed in Green Lake for safer navigation; a new screen-gate was put at the foot of Green Lake to prevent the escape of fish; a portion of the road leading through the grounds was graded; a brick cistern was built in the superintendent’s quarters and one in the foreman’s quarters; minor repairs were made to the superin- tendent’s cottage, such as strengthening the first floor by additional posts, strengthen- ing the roof construction by additional collar-beams, and walling up the foundation of the earth closet; the siding and roof of the ice-house were repaired; the dam at Mountainey Pond was strengthened and leaks in the main supply flume were stopped. 4 REPORT OF COMMISSIONER OF FISH AND FISHERIES. Craig Brook Station, Maine.—Completion of stable and annex to superintendent’s cottage; building of a small settling reservoir; deepening of ponds; repairing hatch- ery annex by laying a floor in the former woodshed and plastering the same for an office and food room; building a small smithy and annex to the farm house; repairing water conduits and flume; and some grading of the grounds. Woods Hole Station, Massachusetts.—Repairs to doors, windows, and blinds of main building; grading along water front of same; repairing flooring of coal wharf; bottoms of boat-landing floats, woodwork around boat EERO NES and small fen basin renewed; and the movable coal hoist repaired. Fish Ponds, Weaving D. C.—Repairs to ponds and embankments, to supply and drain pipes, hydrants, grounds, etc. The north half of the first floor of the super- intendent’s cottage was strengthened for storing books thereon. Bryan Point Station, Maryland.—Improvements on the grounds; the rebuilding of a landing; and minor repairs to buildings. Wytheville Station, Virginia.—Repairs to ponds; laying additional supply pipes from spring to ponds, hatchery, and railroad; new spawning beds prepared; pond walls and embankments repaired; blind ditches opened; and a flagstaff erected. Northville Station, Michigun.—The erection of adam with fishway across the north branch of the Rouge River, 2,400 feet southwest of the hatchery grounds; the con- struction of a brick reservoir on the grounds, and the laying of an 18-inch water conduit of terra cotta from said dam to the reservoir on the grounds, capable of sup- — plying 2,000 gallons of water per minute; repairs to the telephone line between the hatchery and the railroad depot; building of new ponds and repairs to old ones; laying new supply pipes from reservoirs to hatchery and ponds; and minor repairs to buildings and outfit. Duluth Station, Minnesota.—Repairs to tanks, flume, crib well, hatchery flooring, and grounds. Neosho Station, Missouri.—Building new ponds, new earth closet, and woodshed; minor repairs to buildings, ponds, walks in grounds, ete. Leadville Station, Colorado.—Repairing the old hatchery, ponds, and a break in the embankment of Lower Evergreen Lake; building a number of new ponds and grading a portion of the grounds. Baird Station, California.—Rebuilding a bridge with rack across the McCloud River; erecting a flagstaff; repairing stable, hatching and spawning houses, and current wheel, and other minor items of damage done by the past floods. Fort Gaston Station, California.—A dam and trap were built at Mill Creek, a tribu- tary of the Trinity River, about 4 miles distant from the station. The auxiliary hatching house on Redwood Creek, 11 miles southwest from Fort Gaston Station, was enlarged. Repairs were made to ponds, supply flume, and buildings. Clackamas Station, Oregon.—A rack was built across the Clackamas River, as well as across the Sandy River, a tributary of the Columbia River, 17 miles northeast of the station, with a dam and flume at the latter; a flagstaff was erected, fish inclos- ures made, new conduits to hatchery laid, and grounds improved. FiSHWAY, POTOMAC RIVER, Congress, by act approved August 5, 1892, made an additional ap- _ propriation of $15,000 to complete the erection of a fishway at Great Falls, in the Potomac River, sections 4, 5, and 6 having been completed during the previous year. Plans and specifications for sections 1, 2, and 3 were prepared, and proposals for the construction were invited by advertisement. But two bids were received, of whicb the lower— that of Isaac H. Hathaway, of Philadelphia—was accepted, and a contract entered into with him by the Chief of Engineers, U.S. A., on November 23, 1892. Sections 2 and 3 and a part of the permanent deflecting dam were completed during the year. REPORT OF COMMISSIONER OF FISH AND FISHERIES. 5 OFFICE OF MECHANICAL ENGINEER. The following is the report of Passed Assistant Engineer I. 8. K. Reeves, U.S. N., detailed by the Secretary of the Navy as the mechan- ical engineer of the Commission: The steam, water, circulating, heating, electric, and gas plants, together with their attachments, pipe connections, etc., which are located at the different stations, have been, as opportunity offered, examined, overhauled, and repaired. In the machine shop at Central Station a galvanized iron pipe coil refrigerator was built and introduced for the aquaria at Central Station for regulating the tempera- ture of the salt-water supply. A water motor of the Tuerk patent was purchased, a hard-rubber pump fitted to the same, and introduced at Central Station, not only to save the expense of $25 per month for gas, but also to allow the necessary repairs to be made to the Rider hot-air pumping engine, which had been in use continually, night and day, for the past three years and needed extensive repairs. After the erec- tion of the above-mentioned motor the pumping engine was put in thorough repair. A Bishop & Babcock air pump was purchased and connected to the different aquaria at Central Station in order to aérate the water. There was also purchased hard- rubber piping for new supply pipe for salt-water circulation for the aquaria. Twenty-five defective tubes in the boiler for the pulsometers at the fish ponds were cut out and new ones put in. The steam, water, and air circulating plants, transporting tanks, and their attach- ments on cars Nos. 2 and 3 were thoroughly overhauled and new piping substituted where required. A duplex pump of the New York Air Brake Company was placed in car No. 3, in order to supply air circulation to transporting tanks. The iron pipe coil-refrigerator in car No. 3 was removed, the system remodeled, and a new galvan- ized-iron coil putin. In the spring a baggage car was purchased and equipped with boiler, circulating pump, feed pump, air pump, tanks, and necessary attachments for circulating water and air during the transportation of fish to the World’s Columbian Exposition. All boilers, pumps, steam-heating apparatus, etc., on the cars of the Commission were thoroughly overhauled and tested. The engines, pumps, boilers, etc., of steamers Plover, Canvasback, Blue Wing, Cur- lew, Cygnet, Shearwater, and Petrel were overhauled, repaired, and tested; and small repairs were also made to the hulls of these steamers where required. The steamer Petrel was hauled out on the railway and hull coppered below waterline. The ~ steamer Blue Wing was also hauled out on the railway and a new sternpost put in. The lead sleeve in the deadwood was found so much worn that a new brass sleeve was putin. A new smokestack was also fitted to the boiler, and new holding- down bolts for engines were introduced. A new awning frame of galvanized-iron pipe was made for the steamer Curlew, and a new awning fitted. The steamer Shearwater was docked in Cleveland, Ohio, and hull and decks calked and painted; the jet condenser was removed, and a copper keel condenser connected. ‘There were also a number of minor repairs made to the hull and machinery of this steamer. A pump in stock was transferred to this steamer, to circulate the water for transporting cans. The gravity water supply at the Duluth Station having failed on several occasions from drought and freezing up, it could not be depended upon, and it became necessary to increase the pumping plant at that station; this was done by the transfer of a pump in stock at Battery Station. This was connected to the wells on the lake shore, which increased the water supply at the Duluth Station about 150 gallons per minute, giving a total supply from the two pumps of 400 gallons per minute. The mechanical and machine work incident to the above-mentioned repairs, alterations, etc., was almost entirely performed by the machinists and firemen of the Commission, the machine work having been done in the different shops of the Commission, which are located at the different stations. 6 REPORT OF COMMISSIONER OF FISH AND FISHERIES. EXPOSITIONS. The Worlds Columbian Exposition, Chicago.—Capt. J. W. Collins, assistant in charge of the Division of Fisheries, continued as repre- . sentative of the Commission on the Board of Management and Control till the latter part of 1892, when he resigned from the Commission. On December’29 Dr. Tarleton H. Bean, assistant in charge of the Division of Fish-Culture, was appointed as his successor on the Board. Columbian Historical Exposition, Madrid, 1892.—The participation of the Commission in this Exposition consisted in the transmission of a complete set of the publications of the Commission. In recognition of this exhibit, the Board of Directors of the Exposition conferred a a bronze commemorative medal, which has been deposited in the United States National Museum. ADDITIONAL FISH-CULTURAL STATIONS. Fish-hatchery at St. Johnsbury, Vt.—In the previous report reference was made to the selection of a site near St. Johnsbury for the fish- cultural station directed by law to be established in the State of Ver- mont. On July 21, 1892, the necessary plat of the site selected and the deeds conveying the different properties to the United States © were forwarded to the United States Attorney-General. The following December that officer certified to the sufficiency of the deeds to vest in the United States valid titles; and in January, 1893, the purchase money was paid to the respective owners. These payments were, to EH. and T, Fairbanks, $1,070; Asa 8. Livingston, $300; John Morgan, $500; Calvin H. Cushman, $600; total, $2,470. By the act approved July 5, 1892, a further appropriation of $10,000 was made by Congress for the completion of the station, to include the erection of buildings, the introduction of water supply, the construction — of ponds, and other features in the development of the station. Owing, however, to the death of the engineer of the Commission and the delay incident to the selection and appointment of a successor, no actual construction work was undertaken during the year. Fish-hatchery in New York.—Under the authority given by the act approved March 3, 1891, for the establishment of a fish-cultural station on or near the St. Lawrence River, New York, a preliminary investiga- tion was made of certain localities in that State with a view to selecting a station furnishing the requirements as set forth in the report of the Commissioner for 1889-91, page 57. A site was examined at Theresa, but no conclusion in regard to the matter was reached at the time. Derogatory reports of the water supply of that place having been received, a further examination was made the following August, and the result demonstrated the unfitness of the site. In view of the ill success that attended investigations looking toward the selection of a suitable site (examinations having been made at Waddington, Redwood, Clayton, St. Lawrence, Richland, Pulaski, and Sand Bank, none of which nearly reached the standard required), aud owing to the lateness REPORT OF COMMISSIONER OF FISH AND FISHERIES. 7 of the season, it became necessary to postpone further investigations . until another season. Fish-hatchery at San Marcos, Tex.—In a previous report reference was made to an investigation with a view to establishing a fish-cultural station in the Gulf States, and to the fact that San Marcos, Tex., furnished a desirable site for a station for the propagation of fresh- water species of fishes. By act approved August 5, 1892, an appro- priation of $10,000 was made for the establishment of such a station in Texas. Before final decision upon the selection of this site a further investigation of certain other localities was made. In November, 1893, an offer was made by a committee of citizens of San Marcos to convey to the United States a tract of land in that town, near the head waters of the river and just below the dam of the San Marcos Water Company; to rebuild and raise the existing dam across the river, so as to provide a higher level and thus permit of the supply of water to the ponds by gravity; to obtain the right to enter upon the property of the San Marcos Water Company for the purpose of laying the necessary pipes and to take fishes from the lake for the purposes of propagation; and to secure the passage of certain city ordinances which would allow of the satisfactory conduct of the station. The consideration to be paid for the tract was $4,500, and for the water rights, dam, etc., $2,500. In view of all these circumstances, it was decided to select the San Marcos site, and the deed of Judge W. D. Wood covering the tract of ground was delivered on the 2d of May, 1893, and that of Mr. Ed. J. L. Green and the San Marcos Water Com- pany for water rights, etc., on the 24th of April, 1893. In accordance with the request of this office of the 14th of April, 1893, the United States attorney for the western district of Texas was directed to receive the papers and examine the titles to the property and rights thereby conveyed. Under date of May 25 the Attorney- General certified that the deed to the Wood tract was sufficient to vest in the United States a valid title to the same. In regard to the prop- erty of the San Marcos Water Company and Mr. Green, it was found that the title was affected by certain deeds of trust given by the com- pany to secure certain issues of bonds, and it became necessary to arrange for releases, so far as the rights conveyed by the deed to the United States were concerned. Steps were therefore taken to secure from the trustees, with the consent of the holders of the bonds, the releases called for by the Attorney-General. This, however, it was impossible to have done before the close of the year, and the respective deeds were held in escrow until the final completion of all the require- ments necessary to pass the property in fee simple to the United States. Fish-hatchery at Bozeman, Mont.—In the last report of the Commis- sioner attention was called to the investigations which took place with a view of selecting suitable sites for the establishment of fish-cultural stations in the State of Montana and in one of the Gulf States. Of the sites examined in Montana, the most desirable for the proposed station 8 REPORT OF COMMISSIONER OF FISH AND FISHERIES. was that embracing Davies Springs, near Bozeman. After a careful engineering survey an option for the sale of the property at $3,500 was obtained. The site embraces some 78 acres of land, on which are the Davies Springs, flowing between 1,200 and 1,500 gallons of water per minute. Certain rights connected with the water supply of Bridger Creek are also secured. The deed of William J. Davies and his wife transferring this property was dated May 20, 1893, and this document was duly transmitted to the United States Attorney-General for exami- nation and certification as to the sufficiency of the same to vest a valid title in the United States. On June 26, 1893, the Attorney-General, in a communication to the Commissioner, stated that this deed was sufficient to pass a valid title to the United States. Afognak forest and fish-culture reserve-—The act approved March 3, 1891, entitled “An act to repeal timber-culture laws, and for other pur- poses,” affecting the acquisition of public lands, provides for the reserva- tion in Alaska of such public lands as “shall be selected by the United States Commissioner of Fish and Fisheries on the islands of Kadiak and Afognak for the purpose of establishing fish-culture stations.” Under this provision of the act the President, by proclamation of December 24, 1892, set aside ‘‘Afognak Bay, River, and Lake, with their tributary streams and the sources thereof, and the lands including the same on said Afognak Island, and within onemile from the shores thereof, as a reserve for the purpose of establishing fish-culture stations, and for the use of the United States Commission of Fish and Fisheries, the boundary lines of which inelude the head springs of the tributaries above mentioned, and the lands the drainage of which is into the same.” COURTESIES RECEIVED AND EXTENDED. At the request of the Secretary of State, information on the fishery laws of various countries was furnished for use in the arbitration of the Bering Sea seal controversy between this country and Great Britain. By direction of the President, the steamer Albatross was transferred to the Treasury Department, for duty in the investigation of the life- history of the fur seal and of the fur-seal fishery of Bering Sea. The Treasury Department granted facilities to Mr. Charles H. Town- send, an assistant of the Commission, to study seal life upon the rook- eries of the Pribilof Islands. Information relative to the hydrographic soundings of the steamer Albatross was furnished the Coast and Geodetic Survey for the Coast Pilot of Alaska. The steamer Albatross was transferred to the Navy Department, by direction of the President, for duty as a patrol in Bering Sea. Capt. W. E. Dougherty, U.S. A., was, by request, detailed by the Sec- retary of War to superintend the fish-cultural work at Fort Gaston, Cal. The Commission is again indebted to Gen. Albert Ordway, command- ing the District of Columbia militia, for the loan of tents and equipment for use in the shad-hatching operations on the Potomac River. REPORT OF COMMISSIONER OF FISH AND FISHERIES. 9 The steam launches Petrel and Canvasback were loaned to the State of Virginia for use in investigating the oyster-grounds of that State. The Standard Oil Company loaned seven tank cars for transporting 42,000 gallons of salt water for the United States Fish Commission aquaria at the World’s Columbian Exposition, and the Chesapeake and Ohio Railroad Company and Cleveland, Cincinnati, Chicago, and St. Louis Railway Company transported the above free of charge from Beaufort, N. C., to Chicago. STATE FISH COMMISSIONS. During the year the policy of aiding, so far as possible, the work of the fish commissioners of the various States has been continued. ‘The extent of this codperation is shown by the following table: Statement showing the kinds and number of fish and fish eggs furnished to State and Terri- torial fish commissions during the fiscal year 1892-93.

Sasaki, Tokyo, were sent eggs of the Loch Leven trout, Von Behr trout, and rainbow trout. DIVISION OF INQUIRY RESPECTING FOOD-FISHES. The work of this division during the year is set forth in the appended report of Mr. Richard Rathbun, assistant in charge. In addition to the regular inquiries of the Commission, the assistant in charge gave much time and labor, at the request of the Department of State, in preparing, for use before the Paris Tribunal of Arbitration, information concerning the condition and character of the more important fisheries of foreign countries and the legislation for their protection and improvement. Owing to the detail of the Albatross for duty in Bering Sea, under the direction of the Secretary of the Treasury, and the necessity of repairs to the ship after the completion of her duties on this detail, the inves- tigations on behalf of the Commission in the beginning of the year could only be incidentally performed. The opportunity was embraced, however, of making a careful study of the seal rookeries of the Pribilof Islands by the naturalists of the ship, who were temporarily detached from her. Upon the surrender of the Albatross to the Commission, on August 31, 1892, it was necessary to give her extensive repairs, which were not completed till the following April, when the President directed that she be placed under the orders of the Secretary of the Navy for duty in connection with the sealing patrol fleet in the North Pacifie Ocean and Bering Sea. Owing to these details of the ship, the system- atic prosecution of the inquiries of the Commission was not possible. It is hoped, however, that another season matters may be so arranged as to permit its performance. On the Atlantic and Gulf coasts much attention was given to the study of the oyster beds and conditions affecting them. Among the grounds examined were those of Chesapeake Bay, embracing Tangier Sound, Mobjack Bay, and the rivers tributary thereto, and Galveston Bay, Gulf of Mexico. At Sea Isle City, N. J., experiments were con- ducted by Prof. John A. Ryder, of the University of Pennsylvania, formerly the embryologist of the Fish Commission, with the view of determining, if possible, a practical method for the collection of oyster spat, and the creation thereby of an industry distinct from, but as prac- tical as, that of oyster-planting. Professor Ryder’s observations on the subject will be found in the report of Mr. Rathbun. REPORT OF COMMISSIONER OF FISH AND FISHERIES. at Reference was made in my previous report to the visit of Dr. Bash- ford Dean to Europe for the purpose of studying the methods there followed in oyster-culture. The results of Dr. Dean’s investigations were issued in December, 1892, and July, 1893, being published in the Bulletins of the Commission for the years 1890 and 1891, and will undoubtedly prove of great aid to those oystermen of this country who are Seeking to improve the industry. The subject of acclimatizing the eastern oyster on the Pacific coast has received attention, and investigations of the physical conditions of certain areas have been made. Favorable conditions appear to exist in Willapa Bay, Washington, and it is proposed to make plantings there from a number of localities on the Atlantic coast as soon as a favorable opportunity may arise. Reference is made to the report of Mr. Rathbun for a résumé by Pro- fessor Libbey of the physical inquiries conducted by him during several preceding seasons off the southern New England and Middle States coast. These inquiries were discontinued during the season of 1892, and the schooner Grampus was used to make a search for the tilefish in those localities where it had previously been found. A few speci- mens only were received. The inquiry, however, establishes the fact of the continuity of the belt of warm waters on the Gulf Stream slope, so as to permit the northward summer migration of the species. We have therefore reason to expect that the tilefish will reoceupy its old grounds in undiminished numbers and that a valuable market fishery will be established should the fish be found acceptable to consumers. At the laboratory of the Commission at Woods Hole studies of marine life were prosecuted as in previous years. The spawning and early habits of the common scallop or pecten were investigated by Dr. James L. Kellogg; Prof. Francis H. Herrick continued his observations on the development and life-history of the lobster; Prof. H. V. Wilson on the development of certain sponges; Dr. William Patten on the sense-organs in the horseshoe crab. The other inquiries conducted will be found noted in Mr. Rathbun’s report. Extensive investigations were made of the shores and inlets of Buz- zards Bay and Vineyard Sound for the purpose of studying the habits and life-history, in the younger stages, of the common food-fishes of the locality, and much important information concerning the breeding and other habits of the menhaden was secured. The interior waters examined during the year embraced the Columbia River and some of its tributaries, in Washington, Idaho, and Montana; the rivers and lakes of Minnesota, North and South Dakota, Iowa, Nebraska, Wyoming, Wisconsin, Arkansas, and California. These investigations were for the purpose of studying the physical character- istics of these waters and also to ascertain the various forms of animal and plant life inhabiting the same. Such inquiries are especially val- uable as a guide in the work of the Commission of stocking our waters with suitable food-fishes. ge REPORT OF COMMISSIONER OF FISH AND FISHERIES. The destructive methods followed in the capture of fish and shellfish in the territorial and contiguous waters of the United States and the British Possessions in North America, as also in the open seas outside of the territorial limits of either country, but which are resorted to for the purpose of fishing by their respective inhabitants, as well as the polluting and obstructing of such contiguous waters, to the detriment of their fisheries, have long been matters which have invited the attention of the respective Governments; and the necessity of uniform mutual laws regulating the prosecution of the fisheries, as also the adoption of methods for the replenishing of depleted waters, have equally been felt to be necessary if the fisheries were to be maintained. An agreement was reached by the two Governments on December 6, 1892, which pro- vided for the appointment of a joint commission of two experts, one on behalf of each government, to consider and report upon the whoie question. As representative on the part of Great Britain, Dr. Wil- liam Wakeham, of the department of marine and fisheries of Canada, was appointed, and on the part of the United States Mr. Richard Rathbun, of the United States Commission of Fish and Fisheries. The two commissioners had their first meeting at Washington, on March 2, 1893. For the general scope of the inquiry to be prosecuted, reference is made to Mr. Rathbun’s report. During the spring and summer of 1893 investigations were conducted to learn what, if any, benefits had resulted from the series of close sea- sons in the spring mackerel fishery, provided by the act of Congress passed in 1886, the information also being needed by the Joint Fishery Commission. The schooner Grampus attended the fishing fleet on the southern fishing-grounds and thence to those off Nova Scotia. Many valuable observations were made, and much important information secured bearing upon the fishery. As the data of several seasons are necessary before any reasonable conclusions on the subject can be reached the consideration thereof is deferred. Other incidental inves- tigations conducted by the division are shown in the report of Mr. tathbun. DIVISION OF STATISTICS AND METHODS OF THE FISHERIES. During the year the administration of the affairs of this division devolved upon Dr. Hugh M. Smith, and reference is made to his ap- pended report for a résumé of the work accomplished. Capt. J. W. Collins, the assistant in charge, retained the general direction of the work of the division up to September 26, 1892, and on December 27 of the same year he resigned from the Commission. The work of the Division of Statistics and Methods of the Fisheries has continued of the same general character referred to in my previ- ous reports. The scope of the operations is, however, becoming more extended and valuable year by year, and the practical usefulness of the division is annually becoming more evident. REPORT OF COMMISSIONER OF FISH AND FISHERIES. 13 The work of the division has consisted chiefly of field investigations of the commercial fisheries, and the preparation of general and special reports based on the data collected by the division. A large amount of correspondence embodying technical information has been sent out by the division; a number of special discussions on fishery topics have been prepared for the use of the Commissioner and others; and consid- erable statistical and other data have been supplied to State officials. The field investigations carried on by this division were addressed to regions having very important fisheries. The previous practice of taking up for investigation each year definite sections or fisheries, depending largely on work already done covering the same subject, has been continued. In this way it is possible, with the present force, to canvass the fisheries of the coast and Great Lakes States about once in three or four years. The inquiries of the division in 1893 were mainly directed to the methods and statistics of the fisheries of the Middle Atlantic States, the New England States, the Pacifie States, and of the mackerel fishery. Several minor subjects were also consid- ered, and the regular agencies at Gloucester and Boston, Mass., were continued. The inquiries in the Middle Atlantic States were in continuation of those of the previous year, referred to in the last report; the Chesa- peake basin and the adjoining ocean shores of Maryland and Virginia were then canvassed, leaving for consideration during the fiscal year 1893 the fisheries of New York and New Jersey and those parts of Pennsylvania and Delaware not tributary to the Chesapeake. The field investigations in this region covered the calendar years 1889, 1890, 1891, and 1892, except in New York, in which the time of the inquiries prevented the agents from obtaining complete statistics for the last- named year. In the appended report of the assistant full references to the scope and results of the canvass of the Middle States are given, including statistics and comparative data. The recent serious decline in the mackerel fishery, and the great attention which the scarcity of mackerel had received, made it desirable to have full statistical and other information upon these subjects. Accordingly, in connection with the other field inquiries, elsewhere alluded to, a canvass of the mackerel fishery was undertaken in the spring of 1893, and arrangements were made for securing more detailed data than had previously been obtained. This work was in progress at the close of the fiscal year. Reference to the accompanying report of the assistant in charge will show the scope and character of the investigation. A study of the important fisheries of the New England States was made in conjunction with the investigation of the mackerel fishery of that region. No general fieldwork had been carried on in this section Since 1889, and in the meantime some noticeable changes had occurred in the condition of the industry which made another canvass in 1893 14 REPORT OF COMMISSIONER OF FISH AND FISHERIES. timely. Special attention was directed to the lobster fishery, whose successful continuance has been seriously imperiled by overfishing. At the close of the year this investigation was well under way. Early in the fiscal year an investigation of the fishing industry of the Pacific States was begun by Mr. W. A. Wilcox, who had made a similar canvass in 1889. Personal visits were made to all fishing cen- ters on the coast and the coast streams, and very valuable data were secured for each of the years intervening since the last canvass. Espe- cially useful statistics regarding the salmon industry were obtained. Although Alaska was not visited, complete statistical information covering the fisheries of that territory were obtained from the firms engaged, all of whom have headquarters in San Francisco or other cities of that coast. In San Francisco and vicinity Mr. Wilcox was assisted by Mr. A. B. Alexander, fishery expert on the Albatross, who was temporarily detached from the vessel for that purpose. The inquiry closed in May, 1893. An account of this work and its results is given in the report of the assistant, and Mr. Wilcox’s full report will be found among the appendices to this report. In connection with the work of the International Fisheries Commis- sion, Dr. Smith, at the request of the United States commissioner, Mr. Rathbun, during June, 1893, accompanied the commission to Boston, Woods Hole, Provincetown, and other New England fishing — centers. The report for this division contains a brief synopsis of the papers, based on the division’s field inquiries, issued during the year. These included statistical and descriptive articles on the fisheries of the New England States, the South Atlantic States, the Gulf States, and of Lake Ontario. The report concludes with notes on some of the more important fisheries, and on certain branches possessing special interest. DIVISION OF FISH-CULTURE. The continued growth of the Commission rendered it necessary that the Commissioner should relieve himself of the direct supervision of the details of this division, the charge of which he had assumed upon his appointment as Commissioner. On July 6, 1892, he therefore appointed as the assistant in charge Dr. Tarleton H. Bean, the ichthyologist of the Commission. Dr. Bean assumed charge of the division and retained its immediate direction till the beginning of the following January, when his appointment as representative of the Commission on the Goy- ernment Board of Management and Control of the World’s Columbian Exposition, Chicago, necessitated his being relieved of other duty. Mr. S. G. Worth, the superintendent of Central Station, was then detailed as acting assistant in charge of the division, the duties of which posi- tion he performed with fidelity and ik for the remainder of the year covered by this report.

REPORT UPON THE INQUIRY RESPECTING FOOD-FISHES AND THE FISHING-GROUNDS. By RICHARD RATHBUN, Assistant in charge. FUR-SEAL INVESTIGATIONS. In the last annual report a brief account was given of the services rendered to the State Department by the Fish Commission in connec- tion with the controversy respecting the sealing question in the North Pacific Ocean and Bering Sea. During the summer of 1891, the steamer Albatross was used to convey the Bering Sea commissioners on the part of the United States to and from the Pribilof Islands. On March 15, 1892, she was detailed to take an active part in the sealing investigations, under the orders of the Secretary of the Treasury, in conjunction with the revenue steamers Corwin and Bear, which service had not been completed at the close of that fiscal year. During the summer of 1892, and again the following year, a very careful examination was made of the seal rookeries on St. Paul and St. George islands, by Mr. J. Stanley-Brown, then acting as a special Treas- ury agent. His work included the preparation of a setof base maps of both islands, on which the outlines of the rookeries were delineated, and also the taking of a series of photographs illustrating the dis- tribution and abundance of seals on prominent parts of each of the rookeries. It was considered that the duplication of these graphic records during a term of years would serve to demonstrate any changes that might take place in the conditions and dimensions of the rookeries and, consequently, in the sizeof the sealherd. The summer of 1893 was the last preceding the meeting of the Paris Tribunal of Arbitration, for whose consideration Mr. Stanley-Brown’s results were especially intended; but, appreciating the importance of further observations in the same line, the Secretary of the Treasury recommended to Con- gress that the work be continued under the direction of the Commis- sioner of Fisheries. Favorable action on this subject was taken in connection with the sundry civil appropriation bill, approved March 3, 1893, which also provided for investigations by the Fish Commission relative to the pelagic habits and distribution of the fur seal. The assistant in charge of this division continued to be occupied during the first two or three months of the cwrrent year in preparing material for the Bering Sea case, respecting the character and condition of the more important fisheries in fureign countries and the methods there pursued for their protection and improvement, F. R, 93-——2 17 18 REPORT OF COMMISSIONER OF FISH AND FISHERIES. OPERATIONS OF THE STEAMER ALBATROSS IN THE NORTH PACIFIC OCEAN AND BERING SEA. Atthe beginning of the year the steamer A ibatross, Commander Z. L. Tanner, U.S. N., commanding, was still on duty under direction of the Secretary of the Treasury, being at Port Townsend, Wash., where she ha 1 recently arrived after coaling at Departure Bay, British Columbia. She left the former place on July 1 for Unalaska, but unfortunately (owing to continuous sea service for a long period, much of the time under trying circumstances as regards sea and weather) her boilers were in bad condition, and in several other respects the ship needed a thorough overhauling. Ten days were consumed in making the passage to Unalaska, where it was found imperative to order a board of survey, which found the boilers unsafe for further use. Temporary repairs were begun at once, to permit of the ship’s returning to San Francisco, but several weeks were required for their completion. The unfinished work which the Albatross had been expected to carry on was assigned to the revenue steamers Corwin and Rush, to which Mr. C. H. Townsend and Mr. A. B. Alexander were transferred to serve as naturalists, and also two seal-hunters and the necessary appliances for conducting the investigations. Taking advantage of the delay, Prof. B. W. Evermann, then acting as chief navuralist of the Albatross, and Mr. N. B. Miller, laboratory assistant, were dispatched to the Pribilof Islands, where they made a careful inspection of the seal rookeries and obtained an interesting series of photographs bearing upon the same. On August 3 the Albatross left Unalaska, having in tow a British schooner which had been captured while engaged in pelagic sealing in Bering Sea, in contravention of the provisions of the modus vivendi then in operation. After delivering this prize at Sitka, she proceeded to Port Townsend and thence to San Francisco, which was reached on September 3. By direction of the Secretary of the Treasury the con- trol of the ship reverted to the Fish Commissioner at the close of August 31, while still upon her passage, having up to that date been in the service of the Treasury Department for a period of 54 months, during which she visited 26 ports and steamed a distance of 14,848 miles, mostly in northern waters. In order to put the ship in suitable condi- tion for further service it became necessary to provide new boilers and to make many alterations and repairs, which were not fully completed until the following April. Beginning on the 25th of that month, a successful trial trip was made, lasting three days, in the course of which investigations of the sea bottom were carried on off Monterey Bay. On May 13 the President directed that the Albatross be placed under the orders of the Secretary of the Navy, for assignment to duty in connection with the sealing patrol fleet in the North Pacific Ocean and Bering Sea, composed otherwise of certain naval and revenue-marine vessels. It was arranged, however, that her commanding officer should receive his customary instructions relative to fishery and fur-seal inves- tigations, which were to be carried out so far as the special duties REPORT OF COMMISSIONER OF FISH AND FISHERIES. 19 devolving upon the ship would permit. The patrol fleet rendezvoused at Port Townsend, Wash., where the Albatross arrived May 24. She finished coaling at Comox, British Columbia, May 31, and proceeded northward by the passage inside of Vancouver Island to the open waters of the Pacific Ocean, where her patrol work began. The vessels of the fleet were so disposed as to cover the track of the seal herd and sealing vessels bound north, but the Albatross was given the western or off-shore route, which placed her outside of the usual course taken by the seals, and none were observed between Vancouver Island and Kadiak. The first sealing vessel was encountered off the southern edge of Portlock Bank, and St. Paul, on Kadiak Island, was reached June 7. From this point, on the following day, the Albatross began working to the westward, boarding such pelagic sealers as were met with and warn- ing them, in accordance with the temporary agreement between Great Britain and the United States, to refrain from carrying on their opera- tions in Bering Sea. On arriving at Sand Point, Shumagin Islands, ' where the sealing vessels often congregate, it was found that none had yet reached that place. Continuing to the westward as far as Amukta Pass, and there entering Bering Sea, the ship proceeded to Unalaska for coal and thence returned to Sand Point, boarding several vessels on the way, one of which proved to be a cod-fishing schooner bound for Slime Bank, off the north side of Unimak Island. Some time was spent among the Shumagin Islands, and the principal harbors were visited. Mist Harbor, on the east side of Nagai Island, a secure and convenient anchorage, was surveyed for the first time, and advantage was taken by the naturalists at each stop to obtain as inuch information as possible respecting the fishes and other marine animals of the region. Leaving Sand Point on June 26, the ship proceeded to Unalaska, and thence along the Bering Sea side of the Aleutian Islands, entering the Pacific Ocean through Amukta Pass, near which she was at midnight of June 30, the close of the fiscal year. Owing to the long delay in port, in consequence of the extensive repairs made necessary by previous service, the Albatross was only 75 days at sea during the year, but the distance steamed amounted to 9,610 miles. Prof. B. W. Evermann, who acted as chief naturalist during the first cruise made on behalf of the Treasury Department, left the ship after his return from Alaska in August, 1892. The per- manent civilian staff consisted of Charles H. Townsend, naturalist; A. B. Alexander, fishery expert; and N. B. Miller, laboratory assistant. The two former were attached to revenue vessels during the summer of 1892, but were with the Albatross during the remainder of the year. No trawling or hydrographic work was carried on except during the short trial trip off Monterey,in April, 1893. Meteorological and density observations were continued, however, during the entire year, and a record was kept of all surface animal life and drift material observed at sea. Full details of the operations of the ship are given in the report of Commander Tanner, forming an appendix to this volume, 7 ¢ 20 REPORT OF COMMISSIONER OF FISH AND FISHERIES. INVESTIGATION OF FISHERIES IN WATERS CONTIGUOUS TO CANADA AND THE UNITED STATES. By an exchange of notes between the Government of Great Britain and that of the United States, an agreement was reached on December 6, 1892, which provided for the appointment of a joint commission of two experts, one on behalf of each government, to consider and report to their respective governments, jointly or severally, concerning the regulations, practices, and restrictions proper to be adopted in concert, on the following subjects: 1. The limitation or prevention of exhaustive or destructive methods of taking fish and shellfish in the territorial and contiguous waters of the United States and Her Majesty’s possessions in North America, respectively, and also inthe waters of the open seas outside of the territorial limits of either country to which the inhabitants of the respective countries may habitually resort for the purpose of such fishing. 2. The prevention of the polluting or obstructing of such contiguous waters to the detriment of the fisheries or of navigation. 3. The close seasons to be enforced and observed in such contiguous waters by the ~ inhabitants of both countries, as respects the taking of the several kinds of fish and shellfish. 4. The adoption of practical methods of restocking and replenishing such con- tiguous and territorial waters with fish and shellfish, and the means by which such fish life may be therein preserved and increased. It was furthermore provided that— The commissioners to be so appointed shall meet at the city of Washington within three mouths from the date of this present agreement, and shall complete their investigation and submit their final reports thereof to the two governments, as herein provided, within two years from the date of their first meeting. The contracting governments agree to place at the service of the said commission- ers all information and material pertinent to the subject of their investigation which may be of record respectively in the offices of the United States Commission of Fish and Fisheries and in the Department of Marine and Fisheries of the Dominion of Canada; and, further, to place at the disposal of said commissioners, acting jointly, any vessel or vessels of either of the said fish commissions of the United States and Canada as may be convenient and proper to aid in the prosecution of their investi- gation in the contiguous and adjacent waters aforesaid. * * * The two governments agree that so soon as the reports of the commissioners shall be laid before them as aforesaid, they shall consider the same and exchange views thereon, to the end of reaching, if expedient and practicable, such conventional or other understanding as may suffice to carry out the recommendations of the commis- sioners, by treaty, or concurrent legislation on the part of the respective govern- ments, or the legislation of the several States and Provinces, or both, as may be found most advisable; but nothing herein contained shall be deemed to commit either government to the results of the investigation hereby instituted. The two representatives appointed in accordance with the foregoing agreement were, on the part of Great Britain, Dr. William Wakeham, of the Department of Marine and Fisheries of Canada, and, on the part of the United States, Mr. Richard Rathbun, of the United States Fish Commission. Their first meeting was held at Washington, on March 2, 1893, at which Dr. Wakeham was accompanied by Mr. R. Venning, of the same department as himself, Dr. Hugh M. Smith, of the United States Fish Commission, acting with Mr, Rathbun. At this conference, \ REPORT OF COMMISSIONER OF FISH AND FISHERIES. 21 which continued several days, the scope of the inquiry contemplated by the agreement and the plans for carrying on the necessary investigations were discussed in full, and arrangements were also made for beginning upon the field work as soon as the season was sufficiently advanced. The waters covered by this agreement are not only very extensive and diversified, but they afford some of the most important fisheries of the world, in the preservation of which both Canada and the United States have a mutual interest. With respect to the open waters of the Atlantic coast it was decided that the mackerel fishery, which is carried on continuously from off Cape Hatteras, North Carolina, to the mouth of the River St. Lawrence, was the only one demanding immediate attention in this connection. At the mouth of the Bay of Fundy, about Eastport, Me., and the neighboring islands, are several marine fisheries which overlap the boundary line. Next come the rivers St. John and St. Croix, flowing in part between the Province of New Brunswick and the State of Maine. Following in succession are Lake Mempbremagog, Lake Champlain, the upper part of the St. Lawrence River, and the entire chain of the Great Lakes, except Lake Michigan, which is entirely included within the territory of the United States. A short distance to the westward of Lake Superior are Rainy Lake and the Lake of the Woods, both situated on the northern border of Minnesota and finding an outlet northward into Lake Winnipeg and thence into Hudson Bay. Farther to the west there are no important waters until we reach the Columbia River, where it crosses the boundary into Washington. Finally, on the Pacific side, are the extensive sounds and straits between British Columbia and the State of Washington, still only slightly developed except as regards the catch of salmon. As it was evident that the members of the joint commission would not have the opportunity of inspecting personally in detail all the fisheries on which they were expected to report, it was arranged on the part of the United States Fish Commission to send out several field parties to make special studies respecting some of the more difficult problems presented. The schooner Grampus was detailed to investigate the offshore or purse-seine mackerel fishery from the time of its commence- ment at the extreme south, as had been done in former years, but in accordance with a more comprehensive plan of operations; an assis- tant was stationed at Fulton Market, New York, to inspect all mackerel brought there both by the purse-seiners and from the nets along the coast, the owners of many of the latter being also supplied with blanks on which to record their catch of this species; and the assistants at the Woods Hole station of the Commission were charged with the study of the breeding and other habits of the mackerel in the neigh- boring region, which is especially well adapted for observations of that kind. A party was also established at Eastport, Me., and another on Lake Erie, while the steamer Albatross was directed to investigate the boundary waters on the western coast at such times as her regular duties would permit. 22 REPORT OF COMMISSIONER OF FISH AND FISHERIES. The members of the Commission, together with Mr. Venning and Dr. Smith, met at New York on June 2, where they began their inquiries respecting the mackerel fishery. From there they proceeded to Woods Hole, Mass., and thence visited all the more important fishing ports on Cape Cod. Subsequently a few days were spent in Boston and Glou- cester, Mass.,and Portland, Me. At all of these places interviews were held with the fishermen, the shore apparatus of capture was visited and many mackerel were examined. At the close of the fiscal year the party was at Eastport, Me., from which place it was planned to go to the Gulf of St. Lawrence. OYSTER INVESTIGATIONS AND EXPERIMENTS. CHESAPEAKE BAY. The oyster survey of Mobjack Bay, begun in May, 1892, was continued during most of the following summer, being completed about August 20. The delineation of the oyster beds and of the areas of scattered oysters in the open waters of the bay, by means of the launch Petrel, was finished early in July. The dredging work was then immediately taken up by the steamer Fish Hawk, Lieut. Robert Platt, U.S.N., commanding, having for its object to determine the actual condition of the oyster beds, including the number of oysters of different sizes to each square yard of bottom. Subsequently the steamer Fish Hawk proceeded to Tangier Sound, on the east side of Chesapeake Bay, where extensive investigations had been carried on the previous year, and repeated its lines of dredgings over the principal beds, in order to ascertain what, if any, changes had taken place in their condition during the intervening twelve months. While the dredging work was in progress the launch Petrel continued the oyster survey up the four rivers tributary to Mobjack Bay, the East, North, Ware, and Severn. Signal stations had first to be established, followed by a triangulation of the streams as far as was considered necessary, after which the location and extent of the natural oyster beds were determined. The assistants of the Fish Commission who were engaged upon this inquiry were Mr. John D. Battle, in charge, Mr. W. F. Hill, and Mr. B. L. Hardin. As soon as this party returned to Washington the construction of the charts to illustrate the results of the investigation, as well as the compilation of the data relating thereto, were pushed rapidly to completion, and copies of the same, together with the cor- responding charts of Tangier and Pocomoke sounds, based upon the surveys of 1891, were supplied, at an early date, to the government of Virginia, to serve as a basis for establishing the outlines of the public oyster-grounds in those parts of the State waters to which they related, after the manner described in the last annual report. A steam launch was also provided for the use of the State party engaged upon this work. That the assistance rendered by the United States Fish Commission in this connection was of great value to the State author- ities of Virginia and was duly appreciated by them may be judged from REPORT OF COMMISSIONER OF FISH AND FISHERIES. 23 the following extracts from two letters received during the year from the engineer in charge: The steam launch furnished by the United States Fish Commission and the copies of the records of that Commission have alone enabled me to finish the work in Tangier and Pocomoke sounds in a short time. * x x x # * x The charts showing the legal boundaries of the natural oyster beds of about half of the Virginia waters have been published. I should never have been able to accomplish this without the assistance rendered by you. The inquiries respecting the food of oysters and the relations of oysters to their environment, by Dr. John P. Lotsy, of Johns Hopkins University, the plans for which were referred to in the last report, were commenced early in July, 1892, and completed the latter part of September. These researches were carried on in the vicinity of Hampton, Va. GALVESTON BAY, TEXAS. In the early part of the summer of 1892 word was received of a sud- den and extensive mortality among planted oysters in Galveston Bay, Texas, and an inquiry into the causes thereof was requested. One company alone had made plantings on 480 acres of bottom of empty oyster shells and seed oysters a year or so old, the latter growing rapidly and the beds being in a prosperous condition as late as the close of April, 1892. During May, however, the oysters began to die without apparent cause, and a month later scarcely anything but empty shells were left upon the ground where a yield of over 300,000 bushels had been expected the following winter. The mortality was not confined to this particular planting, but was said to have extended also to the wild oysters in other parts of the bay. In August Mr. John D. Battle was detailed to investigate this matter, and at the same time to make a general examination with respect to the oyster resources of the region, to serve as a basis for possible future inquiries on a more extensive scale. Only a short time was spent upon this work, but considerable information was obtained. With regard to the question of mortality, the subject was studied from several standpoints. Too great an influx of fresh water has been considered a frequent cause of such destruction. However, the only sources, except seepage and local rainfall, from which a supply of fresh water can reach Galveston Bay are the San Jacinto and Trinity rivers, ‘both of which are relatively small as compared with the main body of the bay. The Trinity drains quite an extensive territory, while the San Jacinto does not, but the fresh waters coming from both of these rivers meet and merge into each other and flow over Redfish Bar into the lower part of Galveston Bay. General inquiries made to ascertain if there had been an tinusual rainfall and freshet in these rivers at or just before the period when the mortality on the planted grounds was first noticed afforded negative results. According to the records in the office of the Weather Bureau in Galveston, however, there had been 24 REPORT OF COMMISSIONER OF FISH AND FISHERIES an average rainfall during April and May, and in March only an inch more than the average. During the same period there had also been some strong northwest and southwest winds. Although Mr. Battle’s visit was made during the dry period of the year, he undertook to ascertain by density observations the point nearest to the planted grounds where fresh water could then be found, both at the surface and. the bottom. A line of such observations was, therefore, run up the bay in a general northwesterly direction, from off the foot of Tremont street, Galveston, and over the planted grounds to the mouth of the San Jacinto River, a distance of 25 miles. At the foot of Tremont street the specific gravity was 1.017 at high water, and 1 mile farther, 1.0166. On section 1 of the planted beds it was the same as the last, and on section 8, three-fourths of a mile away, it amounted to 1.0164. Beyond the area of the planted grounds the observations succeeded one another as follows: About 1 mile WNW. of the west end of Pelican Island, 1.0147; about 1 mile SE. of Half-Moon lighthouse, high tide 1.015, ebb tide 1.0142; about 200 yards from Half-Moon light-ship, 1.0144; about 1 mile NNE. of Dollar Point, ebb tide 1.0132; about 2 miles south of Redfish light-house, ebb tide 1.007; Redfish Beacon, 1.0036; about 400 yards SE. of Northwest Beacon, 1.002. Five subsequent sta- tions were made, the last about 1 mile NW. of Red Bluff Buoy, where the water was practically fresh both at the surface and bottom. Information was furnished to the effect that the water in the bay is never fresher than at the time of year when this examination was con- ducted, but Mr. Battle is inclined to doubt the correctness of this view as not being based upon scientific observations, and, moreover, the occurrence of any particular freshet having its origin from 25 to 30 miles away might easily escape detection by those living along the sea. Such a freshet would undoubtedly bring the fresh-water point much nearer to the Gulf and might radically affect both planted and natural oyster beds. Even if the salinity of the water is as great at all sea- sons as it was in August, Mr. Battle thinks his observations clearly demonstrate that it would be the height of folly to plant oysters north of Redfish Bar. Empty shells are much more numerous than living oysters on this bar, and he has no doubt that fresh water was the main factor in their destruction. An oysterman of long experience in this region recalls that oysters have twice been destroyed in Galveston Bay within the past twenty-five years, ouce by fresh water and again during the great southeast storm of 1875, which lasted several days and swept everything before it. Mr. Battle next made a critical investigation of the planted beds and of the natural beds nearest to them, with the object of determining their relative condition as to mertality and the character of the bottom. Samples were obtained by tonging from all of the eight sections of the planted ground. The total amount of material brought up was 14 bushels, which contained 46 adult oysters and 992 spat. The oysters were generally in groups or clusters, seldom single. The living adults REPORT OF COMMISSIONER OF FISH AND FISHERIES. 25 seemed to be in as good condition as those examined on the natural beds, and the spat was still attaching and thrifty. Drawbridge Reef, about 24 miles southwest of the planted beds, which was next examined, is one of the best grounds as regards quality of oysters, but it has been overfished. It showed no signs of any special destruction which could be attributed to a late cause. It occupies a stable shelly bottom where the observations were made. On Blind Shoal Reef, another shelly bottom, about a mile northwest of the planted grounds, dead shells were more numerous, which may indicate a greater mortality, and the oysters were not so finely shaped as those on Drawbridge Reef. This bed is nearer the fresh-water point, but the density determinations were as high as 1.0126 and 1.013. The oysters on Half-Moon Reef, judging from the shells, show some deaths which may have been of late date, but not enough to assign any other cause for mortality than that of old age and the usual casualties. ° Finally, the character of the bottom on the planted beds was tested by means of a sounding pole, which showed it to be generally soft, and jn some places very soft. The pole would usually go down very easily a distance of 10 to 12 inches through the mud before it reached a harder substratum. Several times shells were felt at a depth of 10 or 12 inches, apparently resting on this substratum. Judging from the softness of the bottom and the mud-stained condition of the shells, Mr. Battle is led to believe that mud has been a factor which will account in part for the destruction of the planted oysters. The general trend of the currents over these beds is southeast and northwest. One may readily conceive that strong northwest winds, which have a sweep down the bay from the mouth of San Jacinto River, would affect objects lying on the bottom in shallow water. It would naturally impart a motion to them and cause them gradually to sink. It is reasonable to suppose also that this disturbance would make the water very thick with suspended mud, especially that part of it near the bottom and immediately surrounding the oysters, and if continued for any length of time would resalt in great injury to the beds. Southwest winds would have a similar but less effect, for the reason that they do not have the same sweep. Comparing the general character of the bottom of the natural beds with that of the planted grounds, it will be found that the former are much more stable, owing to the yearly accretion of shells on which the living oysters grow. The plantings already made on the artificial beds, amounting to 400 bushels to the acre, may possibly furnish a foundation which will render the bottom more stable and result in the formation of a continuous oyster bed in the course of time, and the chances of success in that direction would be greatly heightened by the addition of more shells. Within 14 miles of the planted area are located mills for the manu- facture of creosote. It had been conjectured that the refuse from these mills might have been responsible for at least a part of the mortality > 26 REPORT OF COMMISSIONER OF FISH AND FISHERIES. above referred to. An examination of the piles of neighboring wharves, however, showed the presence of adult oysters and spat ina flourishing condition, as well as an abundance of other forms of life which are generally found in such situations. The pungent odor of creosote was very strong under the nearest wharf, but it did not seem to affect the welfare of the oysters there, although they appeared to Mr. Battle to leave an astringent taste in the mouth. A sample of the water and specimens of oysters from the wharves were afterwards subjected to chemical examination in Washington, without discovering the presence of creosote or of any other poisonous matter. Besides the inquiries above referred to, Mr. Battle also located approximately all of the natural oyster beds in Galveston Bay. There are none in the deeper parts of the bay, probably owing to the soft character of the bottom, but they are situated on shoals, from which, in some instances, they have encroached on the adjacent soft bottom by yearly accretion. Except for the preponderance of this soft bottom the conditions seem favorable for oyster-culture south of Redfish Bar, in case the water is never fresher than in August for any length of time. The only enemies known are the drill, conch, and drumfish, no harmful starfishes, it is asserted, finding their way to the oyster beds. SHATISEE GEPY, N. di In the last annual report reference was made to experiments by Prof: John A. Ryder, of the University of Pennsylvania, respecting the col- lecting of oyster spat in accordance with an entirely new method, which promised excellent practical results. Formerly, while a member of the scientific staff of the Fish Commission, Professor Ryder’s energies were directed chiefly toward the solution of this important and perplexing problem, which involves the prosperity of a large proportion of our coastwise population. His work was then carried on mainly at St. Jerome Creek, Maryland, and at the Woods Hole station of the Fish Commission, and, although fair success was met with, it fell short, for some reason, of the practical benefits which had been anticipated. During the season of 1891, taking advantage of the facilities afforded by the marine station of the University of Pennsylvania at Sea Isle City, N. J., Professor Ryder started upon a new series of experiments differing radically from any he had tried before. The incidental expenses of the work that year were met by the university. During the next summer, 1892, codperation with the Fish Commission was accepted to the extent of paying for the appliances and supplies necessary to conduct the work upon a larger scale. The following extracts from letters written by Professor Ryder in May and June, 1892, will serve to explain his plans: I propose this summer to conduct a series of experiments on a wholly new line. I think most of us have been mistaken in our way of looking at the question. I want, this year, to produce from 30 to 60 bushels of seed oysters to the square rod. Ihave already experimented far enough at Sea Isle to show that such an estimate is not REPORT OF COMMISSIONER OF FISH AND FISHERIES. 27 extravagant. * * * I firmly believe that the culture of oyster spat or seed is as practicable as bee-culture, and that it may be profitable also. I believe that the production of spat or seed oysters can be carried on in concentrated or condensed form, and that it may and will become a distinct industry from that of oyster planting. It will inevitably come to this, and will be as scientific and precise in its knowledge of conditions as bee-culture. Ihave just returned from a visit to Sea Isle City to inspect my last year’s experi- ments in oyster-culture. I find, to my surprise, that spatting is already in progress there, and I inclose with this a young oyster which I should judge was already three weeks old. These results, together with my Chesapeake Bay observations made in 1880, prove that the spattins period extends over four or five months. My method of working there has resulted in the development of what I believe must eventually be the method of rearing spat on a large scale for commercial purposes on an apparatus that will cost 30 cents per square yard. The yield from the very small plant already in use promises the first year from 1 to 3 bushels of seed oysters per square yard, ranging from 2 to 24 inches in length. The method is, in fact, applicable where the bottom consists of ooze and is unfit for planting, and will enable the oystermen of New Jersey to reclaim thousands of unused acres of riparian territory. My plan is essentially the creation of an artificial bottom or bed which shall be at all times acces- sible for cleaning, sorting, spawning, and growing oysters to marketable dimensions. It also makes it possible to use the whole spawning season, four or five months, with clean shells for the whole time. Moreover, there is no loss of shells in the mud, so that shells once brought to the bed can be used until they have caught spat. This does away with the wasteful results of sowing shells on the bottom. Since I have returned I have visited Sea Isle and met one of the oystermen there, who is very much interested. He told me that if he could do on a more extensive scale what I succeeded in doing there last year on a small scale, he would not here- after need to import seed from the Chesapeake. He will supplement my work with experiments of hisown. This, from a practical man who has been in the business for many years, is, it seems to me, a pretty strong indorsement. The framework for holding the cultch and breeding oysters was con- structed in the early part of July, 1892. It consisted of six squares of No. 16 galvanized-iron wire netting, each 1 rod square and having a 2-inch mesh. These squares or frames were supported on cedar piles driven into the soft mud and jointed with stringers of light pine. The entire outfit was very cheap, costing only a little over $60, inclusive of the oyster shells planted upon it, and will last for two or three years without repairs. This apparatus was arranged in the wide tide-water ditches which had been cut to drain the land about the laboratory at Sea Isle City. The wire screens were placed about 6 to 8 inches below high-water level, so that when covered with 30 to 50 bushels of clam and oyster shells as cultch, together with a few adult oysters to furnish the spawn, the top of the bed was nearly uncovered at low tide. The idea was to have the cultch as near the surface as possible, in order that the fry might have a proper chance to set. The experiments of the first year, 1891, afforded very encouraging results, as at the end of eleven months some of the spat had attained a length of 3 inches and would have made cullings or good plants. In that year they obtained as many as 30 to 40 bushels of seed to the square rod, including the old shells to which they were attached. At this rate the possibility of growing seed from cultch thus treated may be considered as having been successfully proved, and at the end of the — 28 REPORT OF COMMISSIONER OF FISH AND FISHERIES. first half of 1893 the original square bed had been transformed into an almost solid oyster bank. In 1892 the six new frames were not in place until later in the season and the results were consequently not so good, but the experiment attracted much attention among the oyster-growers of the neighborhood. The satisfactory outcome of Professor RKyder’s experiments induced the legislature of New Jersey to appropriate $5,000 annually for three years to supplement his work upon a practical scale. In discussing the manner in which this sum could best be expended Professor Ryder has expressed himself as follows respecting the method which he would prefer to see tried: If any action is to be taken in the matter, sites should be selected, under intelli- gent direction, at different points in the State at once, and work begun to carry out the experiments on a large, practical scale. If successful, this investment by the State of $5,000 per year will be an absolutely insignificant sum in comparison with the resulting development of an industry worth millions of dollars per annum to her citizens. My plan, based partly upon the experimental results of the past obtained by myself and others, is something like the following: First of all, having obtained a suitable place where oyster spatting is known to occur naturally and abundantly, and where the salinity of the water is about right, or somewhere between 1.014 and 1.022, according to a standard hydrometer, a site is to be selected for the establish- ment of the plant, which should be in complete working condition not later than the 25th day of June next. This siteshould be of such a character as will enable the construction of an inclosure or pond on a pretty large scale, say half an acre at least. It might even be that a pond would have to be excavated near the shore; but in any event the plant should be so arranged that, under the given conditions, the most economical plans of construction could be followed. This pond should be com- pletely shut off from all direct tidal connection with the sea while in use, and lie, if possible, in a perfectly accessible position from all sides, somewhat higher than sea level, though it should be possible to fill the pond from the sea if necessary. The pond, which we will designate A, should represent an area, say, of from one-half to 1 acre, with a platform resting upon piles, quite near the surface of the water. This platform is formed of galvanized netting, 2-inch mesh, costing 3 cents per square yard, and supported on piles and stringers. It will hold a layer of oyster shells 3 or 4 inches thick, or 40 bushels to the square rod, or from 800 to 1,600 bushels of oyster shells, according as the size of such a pond and platform equals one-half or 1 acre. This is our nursery for clean oyster shells, clam shells, pots- herds, tiles, or anything that young swimming oyster ‘‘fry” will cling to in order to grow into the condition of the young oyster, or ‘‘spat,” as it is called. There should be another platform, B, of an area of one-fourth acre, covered thickly, say, with 100 to 200 bushels of adult spawning oysters, and the whole immersed, say, 6 inches or 1 foot below extreme low water. This area should also have a ledge of heavy planking constructed all round it, so as to prevent the ‘‘fry” of the oyster during its floating stage from being wafted away by the tides and lost. Where a natural oyster reef exists the platform would not be needed, since such a reef near by would amply supply the millions of fry that would be required for our experiments. Next there must be a wind engine and tank for pumping the sea water through pipes from all parts of the area B, and from near the surface, where the floating or swimming “fry” is very abundant. This sea water, charged with its oyster ‘“ fry,” is then carried to the far side of the pond A. The water then flows from outlet pipes toward escape pipes and back to thesea. In this way, with only slight provisions for filtration, and perhaps a tank under the wind engine for allowing the coarsest REPORT OF COMMISSIONER OF FISH AND FISHERIES. 29 sediment to subside, billions of oyster ‘‘fry” can be pumped from the area B through the mass of shells covering the platform A. The best possible conditions could be maintained and the shells could be kept clean in the pond A by overhauling them by hand from time to time, giving each one a shaking in the water, so as to always present clean surfaces for spatting during the six to eight weeks within which that occurs. With such a plant, costing about $1,000 to $2,000 for its first installation, I would expect that something of permanent value might come, and that such establishments would become the basis for more extensive enterprises controlled by private capital. The device here described provides many things in the best and cheapest form, though it is not assumed that the plan may not be greatly improved and perhaps modified as a result of practical experience. The aims to be sought are: (1) A vast amount of surface in the form of clean shells supported upon a platform, placed in position about the Ist day of July, when (2) the wind engine may be started to pump the water charged with ‘‘fry” from the bed of adult spawning oysters. (3) The “fry” should be pumped from the surface, where it swims foratime. This, T think, isan important point. Past experience shows that the passage of the ‘“‘ fry” through a pump does not injure it. With such a plant, and in the light of past experiences at Sea Isle, especially the season of 1891, for every bushel of shells put into the nursery I should expect a bushel of seed. Past experience shows that this seed will, in the space of twelve months, reach a size of 24 inches. This estimate I believe to be a fair one, and since the installation or plant is practically a permanent fixture, the possibility of conducting such establishments as permanent nurseries for the production of seed oysters for planting is seen to be a practical matter awaiting a practical test. Oysters are like potatoes; they will stay just where you plant them. The only one of their stages that is locomotive is the “ fry ” or swim- ming stage. Withsuch a device as the above we get the maximum possible spatting capacity from an abundant source of fry production. That source should be at least 200 bushels of adult spawners—better still if it were 2,000 bushels. This last number of spawners should yield at least 600,000,000,000 of fry. This vast multi- tude of young oysters pumped through 800 to 5,000 bushels of shells should yield an abundant supply of spat capable of growing into “plants” or seed oysters, fit for restocking exhausted beds. The time may come, as it already has in parts of the country, where oyster and clam shells can not be obtained in sufficient quantity to serve as the ‘‘cultch” or nidus upon which the “fry” is to attach itself When this happens it will be an easy matter to produce a cheap kind of tile or earthenware by machinery, in curved flakes somewhat like the oyster shell itself in shape, that can be “ burned” or “kilned” somewhat after the manner of bricks. This material could be produced in vast quantity and very cheaply for the purpose of furnishing the foundations for the ‘“‘spat” or seed oysters in these oyster nurseries of the future. The experiments conducted under my direction at Sea Isle for the past two years, on behalf of the United States Fish Commission, have served to show what the probabilities of arti- ficial oyster-seed culture may some day become when pursued with sufficient capital and energy. : PACIFIC COAST. While it has been impossible during the past year to undertake any extensive investigations or experiments respecting the subject of increasing the oyster supply on the Pacific coast, observations upon the temperature and density of the water in places supposed to be favorable to oyster growth have been made whenever the opportunity permitted. Such inquiries, continued from year to year, as they have been in the past, will ultimately yield information of great value to those desirous of attempting the establishment of new oyster plants from one e 30 REPORT OF COMMISSIONER OF FISH AND FISHERIES. source or another. There are several bays along that coast which seem to be suitable for the introduction of Atlantic stock, and it is now pro- posed by the Fish Commission, as soon as the necessary arrangements can be perfected, to make a small planting of the eastern species, prob- ably at Willapa Bay, Washington, where the character of the bottom and salinity of the water appear to favor the success of such an experi- ment. Great interest is now manifested along the entire extent of the Pacific coast in respect to the oyster question in general, and letters requesting advice as to where the best seed can be obtained or as to the conditions necessary to insure the growth and welfare of this mollusk are constantly received. EUROPEAN METHODS OF OYSTER-CULTURE. The last annual report contains a reference to important studies respecting oyster-culture in France, made for the benefit of the Fish Commission during the summer and fall of 1891 by Dr. Bashford Dean, of Columbia College, New York.’ Before the close of that year Dr. Dean extended his inquiries on the same subject to Spain and Portugal, and during the one just past he has visited Italy, Germany, Holland, Belgium, and England on a similar mission. A report upon the results of his observations in those several countries, accompanied by many instructive illustrations based upon photographs made by himself, has recently been received and published.’ It will prove of great interest to all the practical oystermen of this country who are desirous of improving the condition of their industry. Dr. Dean’s field inquiries were conducted with great care, strict attention being paid to all impor- tant matters of detail; and in the preparation of his report he has taken exceeding pains to present in a concise form the different subjects of which it treats, without omitting, however, anything essential to their complete understanding. The reasons for extending these researches to other countries than France are explained by Dr. Dean as follows, in the introduction to his last paper: . The methods in use along the ocean coast of France are, in general, similar to those of the neighboring countries. It has, however, seemed important to understand the cultural modifications rendered necessary by changes in climate, shore characters, and saltness of water. Local conditions may not unnaturally have favored one par- ticular locality to such a degree that methods of culture there in use might prove of little value in other and even neighboring regions. By general comparison a more distinct idea may be obtained of the actual character and extent of artificial culture. Thus may be seen by what manner and means one country of Europe has taken advantage of the practical successes of a neighboring one, has modified processes to suit local conditions, found by experiment to what limits imported methods may be carried, and succeeded or failed in securing the most judicious governmental aid in obtaining concession of cultural lands and in preserving the natural supplies of spawning oysters. 1Report on the Present Methods of Oyster-Culture in France, by Bashford Dean.

REPORT OF COMMISSIONER OF FISH AND FISHERIES. ob The industry is discussed by Dr. Dean separately for each country, comprising in each case an account of the distribution and character- istics of the natural beds, of the methods employed in cultivation, in the production of seed and the rearing to adult size, and of all other matters bearing upon the subject of oyster production and preserva- tion. The importance of the suggestions contained in this report, as well as in the preceding one, can not be overestimated, and it is sin- cerely to be hoped that the oyster interests of this country will be mate- rially advanced thereby. Some of the more significant of Dr. Dean’s conclusions are quoted herewith: It would appear, for example, that the degree of density of the water is one of the most important factors influencing the spawning and fattening of the oyster. * * * The density of the water recorded in the best spawning-grounds of the French coast is practically that of the spawning-grounds of Italy and of northern Europe. * * * The specific gravity of the water in regions of maximum pro- duction throughout Europe appears to be uniform at about 1.023 in the case of the “flat” oyster (Ostrea edulis), and at about 1.021 in the case of the Portuguese species (Ostrea angulata). The influence of warmth is not to be underestimated in regard to the time and degree of spawning. The amount of spat occurring annually in a region appears to be directly in pro- portion to the number of spawning oysters in that region. This is by no means a novel suggestion; it is one, however, that has been repeatedly impressed upon the writer. The older idea, it will be remembered, is that banks can never be exhausted, on the ground that the few oysters left by the dredgers will, by the annual spawning of several millions of young, cause a very rapid regeneration. That the banks regen- erate is true, but the process is shown to be slow and beset with many difficulties. * * * JItshould be noted that only in those places in Europe where the natural bulk of spawning oysters is actually maintained does a great quantity of spat occur regularly; also that where the number of spawning oysters is equal, the percentage of spat will be notably greater if the spawning oysters are little disturbed. The amount of oyster food appears to be notably characteristic of a locality whose normal food value is represented by conditions of warmth, density, and richness in the organic and inorganic salts, which serve to rapidly generate the oyster-food organisms. Should this natural food value of a locality be a high one, culture has demonstrated empirically that the number of oysters that may be reared is excced- ingly great. It would appear that the number of oysters to be fattened is directly proportioned to the food normal of the locality and to the volume of water which passes over the bed. The actual size of a natural oyster bed is limited by other reasons than that of a failure of the food supply in the neighborhood. * * * The system of stated oyster reserve has been the key to the success achieved by the French and Dutch industries, and has alone rendered it possible for these two countries to supply the entire seed market of Europe. To obtain seed oysters by collectors is shown to be possible only when a regular yearly fall of spat is thus assured, Proximity to a large stock of spawning oysters is one of the imperative conditions of artificial production, a condition that has been too often lost sight of in experiments made along the Atlantic coast of the United States. Collectors in Europe are placed on no river bank or sunk in no stream save where the culturist is fairly sure of a set that will be at least profitable. If experiments iu artificial pro- duction are to be made in the United States, the suggestion given by European oyster- culture is to secure for the purpose a particular part of beach, near the line of low water, where spat has been found to regularly occur. If a trial demonstrates that the locality is favorable, the European culturist would then gradually and carefully expend his money in the purchase or preparation of a more extended area for collect- ing and would study to provide the most suitable form of collector. * * * an REPORT OF COMMISSIONER OF FISH AND FISHERIES. There can be no doubt that artificial production would succeed in American waters. The question is the practical one, whether it would, on an extended scale, be less costly than the price of natural seed. This can only be determined by experi- ments in a favorable locality. * * * The phase of European oyster-culture that has as yet no equivalent with us at home is that of the extreme value of land at particular points. * * * The general need in the United States for areain which to extend oyster-culture can hardly be regarded as immediate. At points, however, where local cultural conditions are exceedingly favorable to rapid growth or fatten- ing, it would seem a practical measure to bring into cultivation extended shore strips near the zone of low-water mark by use of tidal parks of the least costly type. x * * ~ ~ * * In those countries alone where government has absolutely preserved supplies of spawning oysters does seed-culture flourish. The permanent closure of a small natural oyster-bearing area has apparently done what has not been done by a close season of the ““R”-less months. * * * That the absolute reservation of oyster- bearing land will have an immediate and important influence upon the production of seed in neighboring areas is a proposition which European experience seems to demonstrate; and the writer would suggest, as in his former report, that the matter of reservation seems far more pertinent to the needs of the American industry than any attempts at artificial production. ~ ~* * Reservation is clearly a gov- ernmental duty, whether State or local. Tbe matter is not a new one, and the condensed experience of Europe merely emphasizes what, with various modifications as to tenure, time, and degree, the authorities on this subject in the United States have already advised. PHYSICAL INQUIRIES. OFF COAST OF SOUTHERN NEW ENGLAND AND THE MIDDLE STATES. As it was found impossible to continue during the summer of 1892 the elaborate series of observations carried on during the previous three years respecting the temperature and other physical observations off the southern coast of New England, it was decided to have the schooner Grampus make a thorough search for the tilefish in the localities where it had abounded before the astonishing mortality in 1882, which seemed to have effected its extermination. Predicting its return upon the results of the physical inquiries recently conducted, it was confidently expected that at least a few specimens would be captured, and such proved to be the case. During the several trips made between the region off Marthas Vineyard and the latitude of the Delaware capes, 8 specimens were secured by means of cod trawls, some of them of very fair size. The investigations of 1892, as well as those of the previous three years, were in charge of Prof. William Libbey, jr., of Princeton College, the Commissioner of Fisheries also taking an active part in the work and accompanying the Grampus in its earlier trips. The following notice of the results accomplished during the past three years has been prepared by Professor Libbey: During the summers of 1890 and 1891 work was continued in the same area of water off the southern New England coast as in 1889, the same limitations, east and west, — and north and south, being observed, except that in 1890 the lines run by the Coast Survey steamer Blake extended 20 miles farther out to sea than usual, or a total distance of 150 miles. REPORT OF COMMISSIONER OF FISH AND FISHERIES. 33 As the steamer Blake could not be spared for this purpose in 1891, the parties upon the schooner Grampus and the Nantucket New South Shoal light-ship were the only ones in the field. As it was considered inadvisable to make a regular series of observations over the entire area this year, such lines were chosen as would serve to bring out the essential character of conditions supposed to exist. Each line run, however, was equivalent to one that had been utilized in previous years, but the distance between the lines was greater. Theschooner Grampus occupied 148 stations along 13 such lines, making a total of about 1,500 serial temperature observations of the water and over 300 determinations of its specific gravity. In the same connec- tion over 11,000 hourly meteorological observations were recorded. The light-ship party was on duty from July 3 to August 17, during which time it made 500 serial temperature and 250 specific-gravity observations of the water, besides a special series of over 1,000 hourly determinations of specific gravity. The hourly observa- tions respecting meteorological conditions by this party amounted to 17,000. The total number of observations made in 1891 was, therefore, 32,000, as compared with 39,000 the previous year, when three parties were at work. The relations of the Gulf Stream to the Labrador current, as brought out by this study, are especially interesting because of their bearing upon the migrations of schools of fishes. The region off the southern coast of New England was chosen for this inquiry because it was supposed that the contrasts between the currents would be more distinctly shown there from the fact of their being forced closer together by the projection of the mainland to the southeastward from its general curve. This expectation was realized in the course of our investigations. The 50° curve of temperature obtained by plotting the observations made at the different stations has been an interesting one from the beginning. It has been the means of demonstrating the fact that there are two sets of conditions under which these two distinct bodies of water come into contact. It will be convenient to speak of these two portions of the main cufrent of the Gulf Stream separately under two headings, namely, the upper portion and the lower portion, Upper portion.—The boundary between the cold and warm waters at the surface is very seldom a straight line, perpendicular to the surface of the water. It marks the position of the resultant of all the forces at work. Of course the general posi- tion of the boundary will be determined by the velocities of the two bodies of water and their direction when they come in contact. If we leave out of consideration, for the present, the wind as an effective agent in the production and directing of the ocean currents, we find that in addition it becomes a most potent factor in the causation of the changes which are produced in the position of the boundary line at the surface. The winds certainly sway the surface waters of these currents one way or another; it may be for miles in one direction or the other; just as they may retard or reenforce them in their general direction. The winds which blow over this portion of the North Atlantic may, for conven- ience, be divided into two classes. One may be said to blow in a southeasterly direction and the other in a northwesterly direction. The general tendency of the first group or summer set will be to drive the warmer waters at the surface toward the coast, thus forcing them above the colder waters of the Labrador current. The other or winter set may be considered to have the opposite effect upon these waters, and the final position reached after a cycle is completed will depend on the relative velocities of the winds. Itis not denied that there are other factors which enter into this result, or that this position is not affected by the physical characters of the | waters, viz, their relative temperatures, densities, etc., but itis claimed that, after due allowance is made for these other factors, the winds are the most active causes of the daily and seasonal variations which take place in the position of this boundary. While these motions may equalize one another and the resultant position remain the same from year to year, it is supposable that there may be an excess in one or the other of these directions for a series of years, with the result that the boundary RR. 93——3 34 REPORT OF COMMISSIONER OF FISH AND FISHERIES. will be carried far from its normal position in one direction or the other, and thus mask the true position of the main body of one or the other of these currents to a very considerable extent. Lower portion.—lt might be expected that in this position only the general causes which produce and modify the currents in the oceans could bring about any change in either their velocity or their direction. But there is no doubt that the cumulative effect of long-continued impulses, as described above, resulting in each case in a gain in one or the other of these directions, will ultimately be felt, and the result will be seen in a change of position of the main mass of the current. When these changes are brought about, they are of such a character as to evade detection, unless the averages of many observations are carefully studied, when the change in the posi- tion of the resultant becomes manifest. The contrast between these two portions of the current are seen in the apparently more flexible character of the upper portion as compared with the lower, the former being characterized by rather rapid changes in position, the latter by much slower motions. The 50° line indicates very clearly the changes which take place in the relations of these currents. During the time when we were engaged upon this study its pre- dominant shape was that of an inverted letter S, the lower part of the inverted letter representing the main body or lower portion of the Gulf Stream. Neither the 40° line nor the 60° line shows any great deflections under any circumstances, thus apparently indicating that they are well within the boundaries of each of the main bodies of their respective currents. A study of the temperature profiles obtained in 1891 showed that the general relations of the currents had remained the same, but it was noticed that during the greater part of the time the curved bend of the lower part of the 50° line touched the edge of the continental platform, covering it completely from the depth of 70 fathoms to that of 120 fathoms in different places. This had occurred once or twice in 1890, but it was then believed to be rather an accidental feature than otherwise. A comparison of the profiles of the three years revealed the fact that there had been a progressive motion during that period toward the shore. In 1889 the lower portion of the curve did not touch the edge of the continental platform at any point within the area we were studying. In 1890 this portion of the curve touched the continental edge both at Block Island and off Nantucket Island in the latter part of the season, and in 1891, as has been said, it touched along the whoie edge of this portion of the platform during the greater part of the summer. The change which was thus produced in the temperature at the bottom along this edge of the conti- nental platform was in the neighborhood of 10°, an item of considerable importance. The effect produced by this change in temperature and its relations to the work of the Fish Commission can be seen to best advantage by reference to a very inter- esting problem in biology with which it has a direct connection. At a conference held in Washington with the Commissioner of Fisheries tle results obtained were carefully discussed. We saw very plainly that if the same rate of motion held good during this year the whole of the continental edge, or at least that portion of it with which we were most directly concerned, would be covered with this warmer water. The idea was then suggested that if such were the case the conditions for the reappearance of the tilefish would be established if environment meant any- thing in the problem. In the years 1880 and 1881 this recently discovered fish had been found in considerable numbers upon the area we were studying, and had attracted so much attention among fishermen that preparations were made to take it upon a commercial scale for the New York and Boston markets during the ensuing season. Unfortunately, however, in the spring of 1882 the water from Cape May to Nantucket became covered with countless millions of this fish in a dead or dying condition. From that time the tilefish (Lopholatilus chameleonticeps) disappeared from this area entirely, and all attempts to find it since then have been unsuccessful. The cause of its disappearance became a sort of biological puzzle. REPORT OF COMMISSIONER OF FISH AND FISHERIES. 35 The fish had previously been caught in a depth of water varying from 60 to 130 fathoms. Its feeding-ground being at the bottom would therefore occur just at the edge of the continental platform. Itis probably a tropical deep-sea species, judging from its relationships, which had migrated northward through favorable inducements offered by an enlarged feeding-ground opened up in that direction. Itis noteworthy that the temperature at which it was caught (50° to 58°) could only be established on the New England coast and at the edge of the continental platform by just such an invasion of warm water as has been described above. Itis only necessary to conceive the whole of the continental edge from Florida to Nantucket thus over- flowed by this warm band of water to see how the regular feeding-ground of a tropical species could be extended so that the fish could follow it throughout the whole of this largely increased area. It was agreed to test these theoretical conclusions during the summer of 1892. In July the Commissioner and myself went out in the schooner Grampus, south of Marthas Vineyard, to the area which seemed to promise a reward for our labors. .We found the temperature conditions right, set the cod trawls and caught the tilefish. During the remaining portion of the summer I spent considerable time tracing out the limits of the area over which the temperature of 50° and above could be found,- using the trawl lines at the same time to ascertain if the fish were there. We found them all the way to the Delaware capes, and were satisfied that though they were not numerous they had taken advantage of the changed conditions to reoccupy this area.

The laboratory was in charge of Dr. James L. Kellogg, of Johns Hopkins University, and the Commissioner was also present during most of the season, giving personal direction to such parts of the investigations as were undertaken for the Fish Commission. The total number of investigators in attendance, not including the regular em- ployés of the Commission, was fourteen; of these, two were engaged in the study of special subjects for the benefit of the Commission. The work carried on by each may be summarized as follows: Dr. James L. Kellogg was occupied mainly with the study of the spawning and early habits of the common scallop er pecten (Pecten irradians), the younger stages of which were found attached in great abundance to ulva in the Acushnet River, near New Bedford, Mass. The breeding season of this species occurs during May and June in this region, and is probably of shorter duration than in the case of many other important food mollusks. During June the young were observed to present very slight variation as to size, and during the two succeeding months the growth was not rapid. The attachment to ulva was by means of a well-developed byssus, the occurrence of which ’ in. the first stages of growth has been recognized for some time. The byssus-forming gland, which.was carefully studied, was found to remain functional until the latter part of August, when it became atrophied, and in the adults all traces of it have disappeared. Late in August the shell in many instances reaches a diameter of two-thirds of an inch, but considerable differences then exist with respect to size. The method of byssus attachment was determined in both the young pecten and the black mussel, and it was made out that in each of those species the byssus could be thrown off at will, the animal crawling about by means of its foot and reattaching. A vestigial organ, probably a non- functional byssus organ, was discovered in the young of Yoldia, another form of Lamellibranch. The practical bearing of the results of Dr. Kellogg’s observations relate to the artificial propagation or transplanting of the scallop, which, during its attached stage, could be transported conveniently in immense numbers with slight danger of loss. Moreover, if reared in confinement, a suitable collector could readily be provided for the attachment of the young, thereby obviating the difficulties attending the handling of large quantities of fry in a free condition. Studies were also conducted by Dr. Kellogg relative to the morphology and physiology of several bivalve mollusks. Prof. Francis H. Herrick, of Adelbert College, Cleveland, Ohio, con- tinued his observations, begun in 1890, on the development and the life-history of the lobster. As previously announced, Professor Herrick is preparing for the Fish Commission a comprehensive report upon the | | REPORT OF COMMISSIONER OF FISH AND FISHERIES. 37 natural history of this important marine invertebrate, which will be based chiefly upon his own studies now in progress, and is designed especially to present that class of facts regarded as essential in per- fecting the methods of its propagation and providing for its better protection by means of legislation. Prof. H. V. Wilson, of the University of North Carolina, nearly com- pleted during the summer his inquiries relative to the development of certain sponges, which he had previously carried on at Woods Hole and at the Bahama Islands. These studies were partly undertaken with the view of using them as the basis for experimental operations in Florida respecting the cultivation of the commercial sponges, but this work has been deferred for the present owing to Professor Wilson’s resignation from the service of the Commission. The report upon his observations, received during the year, has been published in the Journal of Morphology.! Dr. William Patten, of the University of North Dakota, was engaged upon the study of the sense organs in the horseshoe crab (Limulus), supplementing his observations on structure by many interesting physiological experiments to determine their functions. These related iny part to the sensibility of this animal to changes in temperature, a subject of great importance in respect to fishes, which it is hoped will soon be taken up. Certain points concerning the annelid worms were studied by Dr. E. A. Andrews, of Johns Hopkins University; the development of the group of mollusks known as chitons was observed by Mr. Maynard M. Metcalf, of the same university; and Dr. James I. Peck, of Williams College, was occupied in preparing a systematic paper on the pteropods and heteropods collected during recent explora- tions of the steamer Albatross. The following persons were also present at the station: Mr. H. McE. Knower and Mr. Lefevre, post-graduate students of Johns Hopkins University, collecting and studying the surface life of the region; Mr. J. Y. Graham and Mr. Farr, of Princeton College, engaged in the study of the anatomy of several local fishes and invertebrates; Prof. E. R. Boyer, of the public schools, Chicago, collecting fishes and marine invertebrates for instructional purposes; Mr. W. McM. Woodworth and Mr. C. B. Davenport, of Harvard University, the latter investigating several forms of hydroids, in continuation of observations begun the previous season. The schooner Grampus, which was employed during the summer months in conducting investigations along the outer margin of the continental platform south of New England and New York, made its headquarters at Woods Hole, and Professor Libbey, in direct charge of that inquiry, occupied quarters in the laboratory during the intervals between the different trips. The steamer Fish Hawk was also at work in Buzzards Bay and Vineyard Sound during a part of the summer. 1Observations on the Gemmule and Egg Development of Marine Sponges, by Henry V. Wilson. Journal of Morphology, 1x, No. 3, pp. 277-406, plates 14-25, 1894. 38 REPORT OF COMMISSIONER OF FISH AND FISHERIES. Mr. Vinal N. Edwards, the permanent collector at this station, whose work has been referred to in previous reports, was actively employed during the entire year in making collections of fishes and in recording the daily catch of the fishermen at all points in this vicinity. In the spring of 1893 special attention was paid to the spawning habits of the menhaden and mackerel, both of which species breed to some extent in this neighborhood. During several weeks of the summer of 1892 the writer was at Woods Hole, carrying on, in conjunction with Mr. Edwards, a thorough investigation of the shores and inlets of Buz- zards Bay and Vineyard Sound with respect to the habits and life-history of the younger stages of the common food-fishes which resort to that region. Extensive collections and observations were made, the more interesting relating to the merhaden, the young of which occur in myriads in most of the brackish waters thereabouts, especially in the Acushnet River at New Bedford and in the Wareham River at the head of Buzzards Bay. At different times during the year visits were made by Mr. Edwards to more distant localities, such as Narragansett Bay and Cape Cod Bay, in search of further information respecting the breeding and other habits of the menhaden. INVESTIGATION OF INTERIOR WATERS. COLUMBIA RIVER. During the early part of the fall of 1892 inquiries were conducted along a part of the Columbia River and several of its tributaries, with the object of determining: (1) The character and extent of the obstrue- tions to the ascent of salmon in the Clarke Fork; (2) the advisability of establishing a hatching station for salmon in the eastern part of the State of Washington. The first of these inquiries originated in a joint resolution introduced in the United States Senate on February 19, 1891, and again on February 9, 1892, calling for an appropriation “to be expended under the direction of the Secretary of War in the removal of such obstructions in the Clarke Fork of the Columbia River as pre- vent the ascent of salmon and other fish up said river and its tribu- taries to the Flathead Lake and other waters in that vicinity.” More definite information respecting these obstructions and the utility of their removal being desired before final action was taken in the matter, the United States Fish Commissioner was directed, by an item in the sundry civil appropriation bill, approved August 5, 1592, to make the necessary examinations; and the same bill also authorized the investi- gations relative to the hatchery site in Washington. These inquiries were placed in charge of Dr. C. E. Gorham, engineer of the Fish Commission, who was assisted in the natural-history work by Mr. Barton A. Bean, of the United States National Museum, and Mr. A. J. Woolman, an ichthyologist of South Bend, Ind. This party reached the upper waters of Clarke Fork, in Montana, the middle of September, and continued in the field about a month. It was found impossible, REPORT OF COMMISSIONER OF FISH AND FISHERIES. 39 _ however, to cover the ground during that period as thoroughly as was deemed advisable, and arrangements have been made to continue the work during the summer of 1893. The principal features of interest brought out by Mr. Gorham’s party in respect to the Clarke Fork may be noted as follows: The upper part of the river was first examined between Flathead Lake and Lake Pend d’Oreille, but within that part of its course no obstructions were discovered which could, to any extent, impede the passage of salmon in case they had free access to Lake Pend d’Oreille. The lower Flathead River drains the lake of the same name and, after flowing first southerly and then westerly: a distance of about 70 miles, unites with the Missoula River to form the Clarke Fork. Just below the lake Flathead River is occupied for several miles by a succession of rapids, with still water here and there, its width averaging about 300 feet, and its depth probably from 6 to 10 feet. Even less active species than the salmon would have no difficulty in passing this point. _ The next place of interest in going downstream is Thompson Falls, situated in the Clarke Fork some sixty-odd miles above Lake Pend d’Oreille. At this point the stream is very much contracted, and rushes through a rocky gorge a distance of several hundred feet. There is also here a fall of about 6 or 8 feet, over which a large volume of water pours, sufficient, it is supposed, to permit of the movements of salmon without difficulty. Immediately below the falls are large eddies and the river there appears as an ideal home for both salmon and trout. The water is clear and pure, and on September 19 had a temperature of 61° to 62° F. The course of the river from Thompson Falls to Lake Pend d@Oreille is clear of all obstructions, and the same is also true with respect to this lake itself, which has a length of about 20 miles between the mouth of the Clarke Fork and the beginning of the Pend d’Oreille River, being, in fact, practically only a general widening out of the river. Below the lake the river is known as the Pend d’Oreille River. From Sand Point it flows almost directly west to the Washington line; thence northwesterly and northerly until within British America, where it makes a sharp turn to the WSW., and empties into the Columbia River within sight of the pole marking the international boundary line. The length of the river within the territory of the United States is Slightly over 100 miles, and in British Columbia about 22 miles. Between Lake Pend d’Oreille and the Idaho-Washington boundary line it presents only a single, rapid descent called Albany Falls, which are located about 14 miles above the town of Newport, Idaho. An island divides the river here, and the Great Northern Railroad crosses it at the same place, making use of the island as the base of one of the bridge piers. ‘The falls are therefore double, being situated on each side of the island. They have a rapid but not vertical descent of between 8 and 10 feet. They are much broken, and at the time they were visited had a good volume of water passing over them; but at 40 REPORT OF COMMISSIONER OF FISH AND FISHERIES. periods of low water their descent would become somewhat more abrupt. Trout pass freely up the falls, and they would therefore present no obstacle to salmon. The river is navigable above these falls to Lake Pend d’Oreille, and below them as far as Box Canyon, a distance of about 60 miles, being generally wide and comparatively quiet, though with a strong current. At Box Canyon the river is confined between vertical walls from 30 to 150 feet high and not more than 70 feet apart in places. Being reduced to such a narrow gorge, the stream becomes very deep and, although comparatively smooth, is very swift and dangerous for boats, but offers no obstacles to the passage of fish. Rowboats pass through the canyon, and a small steamer was taken through at one time. This part of the river could be greatly improved for navigation by the removal of a few obstructions at sight expense. About 7 or 8 miles below the canyon and about 35 miles above the mouth of the Pend d’Oreille River are the Metaline Falls, the most serious of all the obstructions in the entire river. Their total descent is somewhere between 25 and 30 feet, more or less broken, and forming rather a series of rapids. On one side are perpendicular bluffs, 30 to 80 feet high, and on the other four large rock masses have fallen into the stream from the mountain which rises abruptly on that side. The possible effect of this obstruction upon the movements of salmon was not determined satisfactorily, although Dr. Gorham inclined to the opinion that it would be insurmountable in its present state, and he suggested that the conditions could be much improved by blasting out the head of the falls and by breaking up the large rock masses which cause the second or lower rush of waters. Below the Metaline Falls the river is wide and deep. About 10 miles below, and 24 miles in a direct line south of the Canadian boundary line, is Big Eddy Canyon, between 2 and 6 mies long, which has been reported to contain several falls. It is very difficult of inspection, and at only a few points, where the walls were somewhat broken, was it possible to get close enough to see inside. The walls are from 80 to 300 feet high, and at one place contract the river to a width of only about 20 feet. The current attains great velocity, but so far as could be deter- mined there are no actual falls in the canyon, and this was also said to be the case by Mr. John Everett, a prospector, who has lived thirty- three years in this region. From here on to the mouth of the Pend d’Oreille there are several rapids or slight falls, but none of great importance. These are all in British Columbia territory, partly above and partly below the Salmon River, which enters the Pend d’Oreille a short distance above the international boundary line. Just above the mouth of the Salmon, all contained within a distance of afew hundred feet, are five rapids or low falls, with a total descent of about 30 feet. The upper one, located at a point where the river is confined in a narrow gorge, scarcely 50 feet wide, has a height of about 5 feet. The second has about the same REPORT OF COMMISSIONER OF FISH AND FISHERIES. Al height; the third is about 6 feet high, and the fourth 4 feet high, while the ‘lower one, quite near the mouth of Salmon River, has a total descent of about 10 feet. In Dr. Gorham’s opinion none of these rapids, unless it might be the lower one, would serve to obstruct the ascent of salmon even during low water, while at times of high water it is quite certain that all difficulties in that respect would disappear. Below the mouth of the Salmon River the Pend d’Oreille flows through a narrow gorge and forms a succession of rapids, after which it widens out and continues less turbulent for some distance; but the last 5 miles of its course are confined within another canyon. At its mouth it is from 150 to 200 feet wide, and before emptying into the Columbia it passes over a fall from 4 to 10 feet high, depending upon the stage of water in the Columbia River. Ordinarily salmon would have no trouble in passing over this obstruction. Kettle Falls, the only important obstruction in the Upper Columbia River, located about 9 miles from Colville, Wash., and 40 or more miles south of the mouth of the Pend d’Oreille, were not visited by the party, but from information obtained from others it is evident that they do not constitute a serious impediment to the ascent of salmon, which for- merly were said to have passed over them in greater or less numbers, although they do not at present. No positive information was obtained respecting the occurrence of the true salmon (Oncorhynchus chouicha) in the Pend d’Oreille River, and it is said that none go farther upstream than the falls at the mouth of Salmon River. The evidence secured points to the fact that the salmon (so called) of both those rivers is the steelhead (Salmo gairdneri), and specimens of this species were observed. There was not, however, sufficient opportunity to study this question satisfactorily, and a pro- longed series of observations may be necessary to determine the range and relative abundance of these two species in the upper waters of the Columbia River. Until conclusive evidence is obtained that the true salmon is prevented from ascending to the upper part of this river system because of the presence of natural barriers and not from other causes, it should not be considered advisable or judicious to expend money im the removal of any supposed obstructions to their passage. _ There are many conditions which require careful study and considera- tion before any definite steps are taken in that direction, and it is intended next year to begin upon a careful and detailed investigation of the subject throughout the entire course of the Columbia River and its tributaries. Inquiries relative to a site for the establishment of a salmon-hatching Station in eastern Washington were confined chiefly to Little Spokane River and Colville River. No success was met with, however, as no locality was found convenient of access and at the same time affording the means for securing an abundance of breeding fish. This subject will also be covered by the proposed general survey above referred to. 42 REPORT OF COMMISSIONER OF FISH AND FISHERIES. MINNESOTA, NORTH AND SOUTH DAKOTA. During July and August, 1892, investigations were carried on in the contiguous parts of these three States by Mr. A. J. Woolman, of South Bend, Ind., assisted during a portion of the time by Prof. U. O. Cox, of the State Normal School, Mankato, Minn. The waters examined were Lake Traverse, Big Stone Lake, and the Minnesota River as far down as Montevideo, Minn.; the Red River of the North as far as the international line, including many of its tributaries; Devils Lake and the James River in North Dakota, the latter being a tributary of the Missouri River. The work was executed in a thorough manner, and was comprehensive in its scope, being directed toward determining the physical characteristics of the different bodies of water visited, as well as their fishes and other aquatic inhabitants, both animals and plants. No extensive ichthyological studies had previously been made in this region, and the report of Mr. Woolman upon the results obtained con- tains many observations of scientific and practical interest. After discussing the geological history of the region examined, which points to the former existence of a very extensive lake, reaching northward to and including Lake Winnipeg, and drained by a broad waterway leading southward through the trough now occupied by Lake Traverse, Big Stone Lake, and the Minnesota River, Mr. Woolman proceeds to describe and account for the present conditions and rela- tions of the principal water areas which he visited. Red River of the North is not the outlet of Lake Traverse, as is often represented on maps, nor has it been in modern times. Lake Traverse and Big Stone Lake, both lying in the valley of ‘‘River Warren” of geologists, are only about 5 miles apart, being separated by sediment piled a few feet above the surface of the former lake. The similarity of the species of fishes living in the two lake basins indicates that at one time they were connected, and yet thenumber of comparatively unimportant or minor differences, quite noticeable and constant, and reaching in some cases almost vari- etal significance, shows the landlocked condition of the fauna of Lake Traverse and points to the fact that these two lakes could not have been united in recent years. Lake Traverse, lying between Minnesota and the northeastern corner of South Dakota, is about 14 miles long by 1 to 14 miles wide, and has a maximum depth of about 30 feet, the average being possibly half that or less. The temperature of the water was high, having been 77° F. when the lake was visited in July. It must change rapidly with the seasons, and in winter the lake freezes to the bottom over much of its extent. There are only two small inlets, and the volume of water in the lake is gradually diminishing. The lake supports a rich and varied growth of plant life, and teems with crustaceans, mollusks, and insects. Nothwithstanding this fact, howewer, it contains few kinds of fishes, none of which can be regarded as abundant. -About the only species utilized as food is the pickerel (Lucius luctus), although a few catfish (Amevurus nebulosus) and strawberry bass (Pomowis) are taken | REPORT OF COMMISSIONER OF FISH AND FISHERIES. 43 for this purpose. No small fishes were observed in the lake proper, and the total number of species obtained from the Jake and its tributaries was only 7. Big Stone Lake is 35 to 38 miles long and 14 to 2 miles wide, with a maximum depth of 35 feet. The average depth is greater than in Lake Traverse, the water is clearer and purer, and it contains but little vege- tation. Invertebrates are also less plentiful, although occurring in sufficient quantities to constitute an ample food supply, and there are many small fishes, such as minnows and darters. In the variety and abundance of its fishes this lake presents a marked contrast with Lake Traverse, 25 species having been secured. [ood varieties are common, the most important being the pickerel, wall-eyed pike, black bass, rock bass, and crappies. From the Minnesota River and its tributaries, between Big Stone Lake and Montevideo, a total of 55 species of fishes was obtained, and from the James River, in North Dakota, 20 species. The Red River of the North presents many features of special interest. It is the only large stream within the boundaries of the United States which finds an outlet toward the far north, suggesting marked differ- ences in its faunal characteristics as compared with other water areas even within the adjacent region, conditions which were not found to exist, however, emphasizing the former connection of this river with the Minnesota and Mississippi. The course of the Red River of the North is northward down a long, gentle slope from a low watershed, which separates its basin from that of the Mississippi on the south, east, and west. Many of its tributaries take an opposite course, in keeping with the streams of the Mississippi system, trending southward until within the immediate valley or flood plain of the main river, when they bend abruptly. The narrow valley now occupied by this river is the product of erosion, and is cut down from 50 to 75 feet below the surrounding level country. Examinations were made at intervals along the main river and also on twelve of its tributaries, the most important of which were the Otter Tail River, Red Lake River, Sheyenne River, as far up as Valley City, N. Dak., and Pembina River, as far up as Minot, N. Dak. Thirty-eight species of fishes were obtained in this basin. IOWA, NEBRASKA, SOUTH DAKOTA, AND WYOMING. The sundry civil appropriation bill approved August 5, 1892, pro. vided for investigations in these several States for the purpose of determining their requirements from a fish-cultural standpoint and of ascertaining the most suitable locations for the establishment of such hatching stations as the circumstances may warrant. It was found impossible to begin upon this inquiry until early in October, and oper- ations for the season were suspended during the first part of November on account of inclement weather, which prevented the carrying on of many of the more essential observations, especially those relating to temperature and other physical conditions of the water.. The investi- gations were resumed in the middle of June, 1893, and were completed 44 REPORT OF COMMISSIONER OF FISH AND FISHERIES. in the middle of August following. The work was in charge of Prof. Barton W. Evermann, assisted in the fall of 1892 by Mr. Lewis M. McCormick, of the United States National Museum, and in 1893 by Prof. U. O. Cox, of the State Normal School, Mankato, Minn.; Mr. Cloud. Rutter, of Long Pine, Nebr., and Prof. R. G. Gillum. of the State Normal School, Terre Haute, Ind. An account of the results of this inquiry must be deferred until the next annual report, to which it properly belongs, only a brief mention being made in this connection of the work accomplished during the fiscal year 1892-93. During October, 1892, many of the streams and springs among the Black Hills and in their vicinity were examined, some of the places visited being Belle Fourche, Spearfish; Rapid City, and Hot Springs, S. Dak., and Newcastle, Wyo. As the cold weather came on the party started eastward through Nebraska, making obser- vations at Ravenna, Lincoln, Crete, and South Bend, in that State, and subsequently at Ames, Cedar Rapids, and Spirit Lake, in Iowa. During June, 1893, the investigations were confined to the southern part of South Dakota and northeastern Nebraska, streams being visited in the vicinity of Mitchell, Chamberlain, Scotland, and Springfield in the former State, and of Niobrara, Verdigris, and Creighton in the latter. As is customary in inquiries of this kind, very complete and detailed observations were made, relating not only to the character and richness of the aquatic fauna, but also to the fitness or requirements of the waters with respect to stocking, their physical and other conditions, and to the relative advantages afforded by different localities for the carrying on of fish-cultural operations, the latter involving the consideration of several important factors, such as the water supply, transportation facilities, and to a certain extent the proximity of natural breeding- grounds, etc. Large collections of fishes and of other aquatic animals were made, a study of which will add greatly to our knowledge of the natural history of the regions examined. WISCONSIN. During the season of 1892 the physical and biological features of lakes Geneva, Delavan, and Winnebago, in Wisconsin, were investi- gated by Prof. S. A. Forbes, assisted by several of his students in the State University of Illinois. The main part of the work on lakes Geneva and Delavan was accomplished during May, but visits were also paid to the same lakes in July, August, and September following. Lake Winnebago was studied during the middle part of June. The contour of the bottom of these lakes was determined by means of soundings; temperature observations were made at the surface and at different depths, and sketch maps were prepared to illustrate their physical characteristics. The biological work consisted in dredging, the constant use of the surface tow net, and in collecting along the: REPORT OF COMMISSIONER OF FISH AND FISHERIES. 45 shores, the inquiries being extended into the creeks, ponds, sloughs, _and other waters adjacent to the lakes. ARKANSAS. Beginning in the summer of 1891, Prof. S. E. Meek, of the Arkansas Industrial University, has carried on, from time to time, in the interests of the United States Fish Commission, important observations relating tothe fishes of Arkansas. In his report upon these inquiries ', Professor Meek has described the principal characteristics of the several rivers and of the more conspicuous springs for which some parts of the State are noted, and has given complete annotated lists of the fishes which are now known to occur in four of the principal river basins, the White River having a total of 84 species, the Little Red River 58 species, the Arkansas River 61 species, and the Illinois River 31 species. The following remarks are extracted from Professor Meek’s report: From an ichthyological standpoint Arkansas is well favored. The State is bordered on the east by the Mississippi, and has four large navigable rivers flowing through it. Two of these rivers, with most of their tributaries, rise in the Ozark Mountains within the boundaries of the State. These streams are fed by many large and beautiful springs, whose waters are cool enough for the mountain trout, their suit- ability being well demonstrated by the success which has attended trout-culture at the several hatcheries already mentioned. In fact, it has been proven not only that trout will thrive in the Ozark Mountain region, but that their growth there is much more rapid than in some other places farther north, where their artificial cultivation is being carried on. The important question for the consideration of the practical fish-culturist is, how many pounds of fish he can secure from a certain number of eggs within a given period and with the least expenditure of artificial food. The records of the Neosho hatchery clearly indicate that fish-culture can be conducted successfully in this direction. While the mountain streams bid fair to contain an abundance of trout in the near future, the larger and more sluggish waters are well suited to the coarser food-fishes native to the State, the most important among them being the black bass, wall-eyed pike, eastern pickerel (Lucius reticulatus), buftalo- fishes, etc. Al] of the important rivers mentioned supply many fishes to the markets every year, and they may continue to do so if assistance shall be given toward restoring, so far as possible, the balance of life in favor of those species which man has done so much to destroy. There is no doubt that Arkansas possesses piscatorial features of a high grade, which warrant more attention in the future than they have received in the past. The angler may find amusement along the picturesque streams of the Ozark Moun- tains, while the fish-culturist will come to recognize in this region one of his richest fields in North America. Arkansas is as yet only thinly settled, and a thorough exploration of the streams of the State before their faunze have been much changed by cultivation would be of great economic and scientific interest. The increase and protection of her food-fishes, both the native and introduced species, can not be suc- cessfully accomplished without a more complete knowledge of the physical and natural-history features of the streams, and it is to be hoped that the means for making such a survey will not long be delayed. 1Report of investigations respecting the fishes of Arkansas, conducted during 1891, 1892, and 1893, with a synopsis of previous explorations in thesame State. By Seth Eugene Meek. Bull. U.S. Fish Comm. for 1894, pp. 67-94. 46 REPORT OF COMMISSIONER OF FISH AND FISHERIES. CALIFORNIA. From 1891 to the close of the fiscal year just past the fresh-water fishes of California have been made the subject of investigation for the Fish Commission by Prof. Charles H. Gilbert, of Leland Stanford Junior University, during such times as his college duties would permit. A report upon these researches has been deferred until further obser- vations can be made, but the field work so far accomplished may be summarized as follows: During the fiscal year 1891-92, the inquiries related to the streams which, draining the eastern slope of the Santa Cruz Mountains and the western slope of the Mount Hamilton Range, enter the southern arm of San Francisco Bay, and those which drain the western slope of the Santa Cruz Mountains and enter the sea between San Francisco and Santa Cruz. These two sets of streams were found to have very different fauns, the former containing, in addition to the fishes of general distribution in California, many of the peculiar forms of the Sacramento Basin, such as Hysterocarpus traski, Archoplites inter- ruptus, Orthodon microlepidotus, Lavinia exilicauda, and Pogonichthys macrolepidotus, which are wholly excluded from the streams draining the western slope of the Santa Cruz Mountains. The latter have only species of general distribution, like the sucker (Catostomus occiden- talis), trout (Salmo gairdneri), sticklebacks (Gasterosteus microcephalus), sculpins (Cottus asper), and occasionally a minnow. Within the past year further examinations were made in the same region, and, in addition, the Pajaro River was studied from its mouth, in Monterey Bay, to the source of its principal tributary, the San Benito River. Los Gatos Creek, Fresno County, was also visited, but was found to be without fishes. This will probably prove true of all other streams entering the San Joaquin Valley from the west, as they are likely to be without running water during part of the hot, dry summer, MISCELLANEOUS INQUIRIES. MACKEREL INVESTIGATIONS. The act of Congress passed in 1886, which virtually prohibited the spring mackerel vessel fishery prior to June 1 of each year during a term of five years, ceased to be operative after 1892. In order to determine, so far as possible, if any immediate benefits had resulted from this series of close seasons, and also to obtain information for the use of the Joint Fishery Commission between Great Britain and the United States, the schooner Grampus, Capt. A. C. Adams in command, was detailed to follow the progress of that fishery throughout its entire course in the spring of 1893. Sailing from Woods Hole at an early date, Captain Adams was directed to conduct a detailed series of physi- cal observations on the way south until the body of mackerel had been REPORT OF COMMISSIONER OF FISH AND FISHERIES. 47 discovered, after which he was to keep track of the movements, habits, and abundance of the latter, and to study the conditions of their environment as far north as Nova Scotia. The presence of a large fleet of purse-seiners on the grounds afforded excellent opportunities for learning of the distribution of the fish at all times, and through their means it was expected that specimens for examination would be obtain- able. The Grampus also made use of the fishing apparatus she had on board, and an hourly record of physical determinations was maintained day and night, besides which the surface tow nets were frequently employed to discover the presence of mackerel food. The natural- history observations were conducted by Mr. W.C. Kendall. Mr. B. L. Hardin was stationed at Fulton Market, New York City, to inspect all arrivals of mackerel there from the purse-seine fleet, as well as from the shore apparatus tributary to that market. The Grampus sailed from Woods Hole on April 10 and reported at Lewes, Del., April 21, having experienced heavy weather up to that date. Very few fish had been observed, and the fishing fleet had accomplished comparatively nothing. The latter also sought shelter at the same place. Poor success, both in the catch of fish and in the opportunities to make observations upon them continued thence to the close of the season, and by the middle of May nearly all the purse-seiners - had left the southern grounds for the coast of Nova Scotia. The small catch made this season was partly due to stormy weather, but, even when all the conditions seemed favorable, mackerel were either scarce or difficult to capture. More light will probably be thrown upon this question when the elaborate series of notes obtained have been worked up, but the fishermen have failed thus far to recognize any beneficial results from the restrictions placed upon their spring fishery during the previous five years. On May 23, the southern fishery having ended several days before that time, the Grampus left Woods Hole, where she had put in for supplies, and proceeded to Nova Scotia, to continue the inquiries on the same plan as at the south. The entire fleet had assembled there, but no fish were taken on this coast, except in trap nets on the shore, until after June 1. By June 5 some of the fleet had done fairly well, the others poorly. After their first appearance on this coast the mackerel moved rapidly eastward, the purse-seiners and the Grampus following them as far as Cape North on Cape Breton Island, the former as a whole making a good catch to the eastward of Halifax, as compared with former seasons. There were 75 seiners on the Nova Scotia shore, and their average fare was about 160 barrels each. The Grampus returned to Woods Hole the latter part of June, bringing a large quantity of specimens bearing upon the breeding habits, food, size, etc., of the mackerel, together with very complete records of the daily observations. Mr. B. L. Hardin remained at New York from April 12 to June 3, and examined every fare of mackerel landed from the southern fishery, 48 REPORT OF COMMISSIONER OF FISH AND FISHERIES. as well as the smaller catches made in the pound nets along the shores. Notes were kept upon the abundance, sizes, and spawning conditions of the fish, and interviews were held with the masters of the different schooners relative to the more important incidents connected with their several cruises. INVESTIGATIONS IN CHESAPEAKE BAY AND ADJACENT WATERS. The fishery investigations begun in June, 1892, in the lower part of Chesapeake Bay and the adjacent waters of the open ocean by the schooner Grampus were continued until about July 20, when that ves- sel proceeded to Woods Hole to take up the physical inquiries along the continental platform, as described above. 740, 000 | 647 Sonny) 4 ee Se Ee eee coca eeooe 1, 200 GOONM Ss Jee ten (Steen reams eee (Saakeeas Lobsters... ..------ 165, 093 15, 655 165, 664 AOS a miciclniototsige MNS mecca 8, 200 410 Wirnssels . -@&-.-2.-. 21, 000 900 6, 000 ODE [PSS seer a sel egeweteaie em oata atcha rete ale DVStCIS oe 25 --- 2-0 18, 277, 434 |2, 748, 509 | 16, 114, 567 /1, 639, 648 |1, 183, 700 |124, 420 |1, 097,040 | 70, 134 IETS ee ose 1,505, 500 | 105, 891 827, 000 Te TO AE arava c\c/ave:| Maye tsiorete a |= -@/arelateta ere ata mietete ote Quahogs......-.-... 4,4, 520)| 650,621 | 3,454,024 | 371, 933, | 5.22. ccelececnce 21, 920 2, 094 Scallops ........-.. 313, 042 EE Ne ete sr 8S) IRON Og ee noaaSrpiccl bShongisd sebsEdrar aocoqeshic OMG ecco. sons noe. 40, 836 GS ph lecee= meee lee ee minister | came = meiem in| pyelopioere||eeselevimmiblniaiaiele sis SSHOMB nets eases a 16, 766, 100 UERUOR el eaiséageecodlesacneeeade BaedeasonallbesenoBdl bectactecod oroadison CED INIS tetra aicict t= mimi o cme olan winia,siaciato 3, 280 TOV Sere See hil ale a caete 11, 988 2, 190 PeSee ee caress |s- 5c c= sub esallascsacisuvelsesseccccrcs|eweccccctclsceccecese|-reccces 18, 000 1, 260 Rota ates «nse 170, 885, 022 |4, 817, 369 | 79, 116, 380 |3, 520, 057 |7, 291, 843 |802, 447 |7, 521, 691 | 250, 290 56 REPORT OF COMMISSIONER OF FISH AND FISHERIES.

The large increase in the population of these States has naturally resulted in an increase in the fishing industry. No accurate comparison can be instituted in the case of Pennsylvania and Delaware, owing to the absence of separate figures for the two drainage systems of those States, but with New York and New Jersey a very Sui: comparison is poseinle: The fishing population of these two States has increased 10,321, of 5,902 and New Jersey 4,419. Considered in the aggregate, the investment in fishing properties has nearly doubled. In New York the number of vessels and boats has increased 3,076, with a value of $311,425; in New Jersey, 1,694, worth $427,868. Among the more prominent changes in the fishing apparatus, it may be noticed that pound nets have come into much more general use and now con- stitute one of the most conspicuous features of the fisheries, while in 1880 they were of littleimportance; the increase in the number operated has been 373, or 500 per cent, the advance being marked in both States. which number New York has REPORT OF COMMISSIONER OF FISH AND FISHERIES 57 This appears to have been largely at the expense of seines, the number of which was reduced by over 1,200, mostly of small size and chiefly in New York. Many more gill nets were found to be employed, the increase amounting to 6,701, valued at $139,952, the expansion of this fishery being due to the development of the shad and sturgeon fisheries in the Hudson and Delaware rivers. The outcome of the fishing industry presents a very gratifying increase, which is participated in by many important products. The aggregate augmentation in the value of the yield was $935,142, of which $591,674 is to be credited to New York and $343,468 to New Jersey. The catch of the following products among others has in- creased: Alewives, bluefish, butter-fish, catfish, eels, flounders, mullet, sea bass, shad, squeteague, sturgeon, tomcod, lobsters, quahogs, and oysters. The following are taken in smaller quantities than formerly, namely: Cod, mackerel, menhaden, scup, sheepshead, Spanish mack- erel, striped bass, soft clams, crabs, and terrapin. THE MACKEREL FISHERY. In May and June, 1893, the field force was placed in the New Eng- land States for the special purpose of making a detailed investigation of the commercial aspects of the mackerel fishery. This inquiry was in progress at the close of the fiscal year. Owing to the great attention the mackerel has recently been receiv- ing on account of the unprecedentedly long period of scarcity, it was important for the purposes of the Commission, in order to afford the best basis for determining the cause and extent of the scarcity, to have accurate and detailed information relating to the various topics which could be legitimately considered by this division. To facilitate the collection of uniform data, provision was made for having the agents obtain the statistics on two printed forms relating, respectively, to the fisheries carried on with vessels and to those carried on from boats and the shore. For the vessel fishery the following information was obtained for each vessel: Name of vessel, hailing port, rig, net tonnage, present value, value of outfit, number and value of each kind of fishing appa- ratus used, the number of crew specified by nativity and nationality, the kinds, quantities, and value of bait canght by the vessel or pur- chased in America or British provincial ports, the number of entries of foreign ports and the expenditures therein for each purpose, the lay of the crew, the quantity and value of each grade of mackerel taken in each region with each kind of apparatus, the fishing season in each region, the number of trips from each region and to each port, and the kinds, quantities, and value of other fish taken with mackerel. In the case of the shore and boat fisheries the information secured for each proprietor-fisherman included the number and value of each form of apparatus employed, the number and value of boats, the fishing season, the number, nativity, and nationality of the fishermen, the wages > 58 REPORT OF COMMISSIONER OF FISH AND FISHERIES. received, the kind, quantity, and value of bait utilized, and the quantity | and value of each grade of mackerel taken with each appliance. A special feature of the inquiry was the provision to obtain complete figures showing, for fresh mackerel, the quantity and value of each standard size of fish taken, and for salt fish the quality and grade of the mackerel packed. While satisfactory figures relating to the differ- ent grades of salt mackerel inspected in Massachusetts are available, no attempts to obtain complete data for the grades of salt mackerel packed in other States or for the various sizes of fish sold in a fresh | condition were ever before made. Owing to the importance of having statistical data for the mackerel fishery covering each year of the “close-time” law, which took effect in 1888 and terminated in 1892, the inquiry was addressed to the years 1890, 1891, and 1892, information for the two earlier years having been | previously obtained. Some supplementary inquiries regarding mackerel were also insti- tuted by the division, by securing the codperation of fishermen on various parts of the coast in recording observations concerning the mackerel during the fishing season of 1895. For this purpose blank books of convenient size were prepared and distributed. They pro- vided for a daily record of the number of extra large, large, medium, | small, and tinker mackerel taken each day, a statement as to the nature | of the weather, direction of the wind, ete. | In the first week in April, 1893, the writer visited New Jersey for the purpose of engaging for this inquiry the services of the pound-net fishermen on the northern part of the coast of that State. This section | is the most southern part of the United States coast on which mackerel are regularly taken in considerable numbers with fixed apparatus. | The fishermen who during the previous season had operated pound nets were personally visited and the object of the inquiry explained to them. They entered very heartily into the matter and agreed to record the daily catch as requested. Record books of a similar character were placed among the pound- net and trap-net fishermen of the Massachusetts coast. The distribu- tion was accomplished through Mr. F. IF’. Dimick, local agent at Boston, — Mass. Fishermen at a number of points on the Maine and Virginia coasts were also communicated with by mail and asked to record their mackerel catch. While it is not probable that all the fishermen receiving the blanks will keep the records requested, there seems no reason to doubt that some valuable information will thus be obtained. In conjunction with his other duties, Mr. E. F. Locke carried on an examination of the spawning condition of the mackerel taken in the vicinity of Gloucester. His work on this subject continued until the temporary withdrawal of the mackerel from that part of the coast and the ending of the spawning season brought the work to a close. REPORT OF COMMISSIONER OF FISH AND FISHERIES. . 59 l THE NEW ENGLAND STATES. , Advantage was taken of the presence in the field of the agents | engaging in the canvass of the mackerel fishery, and investigations of ; a number of other important fisheries of the New England States / were undertaken. The time and force were not sufficient, however, to ‘permit a canvass of all the commercial fisheries of the region. The study of these fisheries, like that of the mackerel fishery, was in ) progress at the close of the fiscal year. The special branches of the industry which were made the subjects ) of inquiry and report were the whale, menhaden, herring, alewife, shad, _ Salmon, smelt, lobster, oyster, clam, and scallop fisheries, sardine and lobster canning, and the manufacture of oil and fertilizer from men- haden. The statistics covering these fisheries were obtained in such form as to exhibit the extent of each, regardless of duplications of ‘men and boats occasioned by their employment in more than one fish- ery. Descriptive notes for all these branches were required wherever changes in methods or conditions had occurred since the last inquiries, /and especially detailed notes were called for on the lobster and a few other fisheries. Perhaps the most important of the fisheries the canvass of which -was.undertaken is the lobster fishery. In my previous report attention was drawn to the great economic value of the lobster, to the very serious reduction in its abundance in recent years, and to the general interest taken in this fishery, whose condition affects a numerous population. As complete a study of the subject was planned as could properly be carried on by this division, and the collection of a very valuable mass of information is anticipated by the time the inquiry is completed. In addition to securing the usual statistical data for per- sons, boats, apparatus, catch, etc., the attention of the field agents was ‘directed to the following topics for investigation and report: 1. The changes in the methods of the lobster fishery since 1880 and in more recent years. 2. The fishing season as compared with other years; the reasons for an extension or shortening of the season; the extent and origin of the fishery during the winter months. 3. The extent of the fishery during the molting season; the catch and destruction of soft, unmarketable lobsters during that period. 4. The depth of water and the distance from the land at which lobsters are now taken as compared with earlier years. 5. Comparison of the present and past average size of lobsters; the present limits of size of marketable lobsters; the proportion of short lobsters to the total catch. 6. Marked changes in abundance of lobsters in a given locality in recent years and the apparent reasons therefor. 7. The relation of the catch to the quantity and character of the apparatus used and to the methods employed. 8. A study of the laws in force and their apparent effect on the size and abun- dance of lobsters in a given locality; the efficiency of their enforcement and the extent of their observance. 9. Consideration of the bait used in the lobster fishery—its source, nature, quan- tity, and value, and the relative effectiveness of different kinds. ib > 60 _ REPORT OF COMMISSIONER OF FISH AND FISHERIES. 10. The sentiment and experience of the fishermen on the questions of (a) close season, (b) taking of small lobsters, (c) taking of molting lobsters, (d) effects of canneries on abundance, (e) results of protection, etc. 11. The extent of the practice of impounding short, molting, or other lobsters; the mortality among the impounded lobsters; the size and location of the pounds; the object an:l results of the procedure. 12. The extent, methods, ete., of the lobster-canning industry. The inquiry regarding the clam fishery included a consideration af the extent of the bait business, one of the most important branche of the fisheries on certain parts of the New England coast. The oyster industry, which has great importance in Rhode Islan and Connecticut and in places on the southern coast of Massachusetts, was studied in detail, the inquiries being addressed to the extent of th planting industry, the methods followed in the cultivation of oysters, the sources and quantities of the seed oysters utilized, the areas o bottom occupied for planting purposes, and other questions havin practical relation to the industry. Provision was made for canvassing in their entirety the fisheries o that part of the coast of eastern Maine adjoining the Canadian province of New Brunswick, in view of the pending consideration by the Inter- national Fisheries Commission of the fisheries of the contiguous waters of the United States and Canada. The branches here prosecuted are the herring, lobster, salmon, alewife, and pollock fisheries, and sardine and lobster canning. THE PACIFIC STATES. Coincident with the inauguration of the field canvass in the Middle Atlantic States, the investigation of the fishing industry of the Pacific States was undertaken. Mr. W. A. Wilcox, the agent who in 1888 and 1889 had conducted an inquiry regarding the fisheries of this section, was again detailed for this work because of his extended acquaintance with the fishing population and his wide experience with the fisheries of the entire west coast. A report based on the previous inquiry was printed as an appendix to the report of the Commissioner for 1888. Mr. Wilcox left Washington August 10, 1892, and proceeded to Portland, Oreg., with instructions to first canvass the Columbia River and then visit such parts of the coast as circumstances or expediency might require. It was important that the extensive salmon fishery of: the Columbia, which was suspended by law on the 10th of August, should receive attention before the fishermen had scattered and the canneries had finally closed, and while the memory of the principal) phases of the season’s work was fresh in the minds of the canners and fishermen. After the completion of the work on the Columbia River, Portland was made headquarters while canvassing the fisheries of the remaining parts of Oregon and Washington. The inquiry in those’ States was completed about the middle of December, and the agent’ then proceeded to San Francisco, Cal., where the investigation of that State was inaugurated about December 20. The inquiry was completed | on May 11, and Mr. Wilcox returned to Washington. REPORT OF COMMISSIONER OF FISH AND FISHERIES. 61 ‘ As in the previous canvass of this region, the work of Mr. Wilcox ‘as efficiently aided by Mr. A. B. Alexander, fishery expert on the lbatross, who was detached from the ship at the beginning of Febru- wey, 1893, and assisted in the investigations in California, He obtained tatistics of the market fisheries of San Francisco, conducted the anvass of Sonoma County and part of Santa Cruz County, and (operated with Mr. Wilcox in the examination of the records of the “astoms house and the transportation companies. |The work of Mr. Wilcox and Mr. Alexander on this coast covered all )hases of the fishing industry. Complete statistical and descriptive iata were collected for the years 1889 to 1892, inclusive. In the case of yartain fisheries in some localities which were visited before the close if the fishing season, arrangement was made for having the informa- von necessary to complete the account of the year’s work forwarded y mail. 7 The details of the condition of the fisheries at the time of the inves- (gation and comparisons with earlier years will be shown in the report if Mr. Wilcox, from which the following condensed preliminary sta- istics relating to the year 1892 are drawn: Persons employed.

REPORT OF COMMISSIONER OF FISH AND FISHERIES. 63 INQUIRIES AT GLOUCESTER AND BOSTON, MASS. _ The services of the local agents at these important fishing ports have ‘been continued. At Gloucester, the most prominent fishing port in the United States, Capt. S. J. Martin has, as heretofore, rendered eminently ‘satisfactory service, notwithstanding the arduous duties and long hours of work necessitated by the character of the fisheries and the nature of ‘the information obtained. The local agent at Boston, Mr. Frederick F. ‘Dimick, is better qualified than anyone else, by virtue of long experience in the work, to represent the office at Boston, and his connection with the Boston Fish Bureau enables the Commission to obtain his services at ;@ Salary not more than one-fourth that which would have to be paid ‘under other circumstances. ° Reference has elsewhere been made to the furlough of these agents during August, September, and October, on vaccount of a deficient appropriation. The loss of data for those months, “while serious, has in part been made up through the voluntary efforts jof the agents. i -In the previous report of the division an outline of the character of ‘its work at Gloucester and Boston was given and its practical value wwas shown. It need only be stated that the inquiries have continued valong the same general lines, and that the information gathered is ithe most complete, accurate, and valuable ever obtained regarding the ‘resources and productiveness of the various fishing-grounds resorted ito by New England vessels. at t MINOR FIELD INQUIRIES. * In August Mr. Edward E. Race, who was then in Maine on leave of absence, was ordered to make an investigation of the menhaden ‘industry of that State. He visited all the factories in the eastern part ‘of the State engaged in making oil and fertilizer from the menhaden ‘and obtained detailed statistical information for the years 1890 and ‘k891. Few fisheries have attracted more attention in Maine than the menhaden fishery; and the recent return of the fish to the waters of Ithe State has caused a revival of the discussion which was suspended ‘during the period of ten years when menhaden were practically absent ‘from that coast. ‘In 1890 menhaden were very abundant on the Maine coast, and four ‘factories, located at Round Pond, Linnekin, and Boothbay Harbor, in ‘Lincoln County, were operated. These were valued at $21,000. The number of shore employees was 306, to whom $38,640 was paid in wages during the fishing season, extending from June to September. The cash ‘capital required to carry on the business was $95,000. The fish were ‘caught and supplied to factories by 9 fishing steamers carrying about 1200 men. The menhaden taken and utilized at the factories amounted ‘to 302,700 barrels, equivalent to about 89,550,700 fish. From these the ‘following products were made: 1,059,000 gallons of oil, with a market value of $264,750, and 10,930 tons of wet serap, or “chum,” valued at 64 REPORT OF COMMISSIONER OF FISH AND FISHERIES. $131,160. The fish were remarkably large and fat, 1,000 yielding about — 12 gallons of oil, on an average, and 8,200 making a ton of wet scrap. The average nee of menhaden to a vessel in 1890 was about 33,633 barrels. Four steamers fishing for one factory averaged 43,750 Ne: each. The following year menhaden were less abundant than in 1890, and the catch fell off over 50 per cent. Five factories, located at Booth- bay, Linnekin, and Round Pond, were in operation. These were sup- plied with raw material caught by a fleet of eight fishing steamers temporarily withdrawn from Rhode Island. The number of persons employed in the factories was 208, to whom $27,350 was paid in wages during the season. The value of the works and their equipments was $53,000, and $83,000 additional capital was required to conduct the business. The number of menhaden utilized at the factories was 40,850,000, equivalent to 123,750 barrels; these had a value of $122,550, or aie $1 per barrel. iicom these the folowing manufactured prod- ucts were prepared: 299,300 gallons of oil, with a market value of $74,825; 1,800 tons of dry scrap, worth $36,000, and 4,250 tons of wet scrap, valued at $50,760, the total value of the oil and scrap being $161,585. It appears from these figures that the fish contained much less fat than in 1890 and yielded less than 8 gallons of oil per 1,000 fish. Mr. W. A. Wilcox made a short visit to Baltimore, in August, 1892, for the purpose of securing certain information on oyster packing to complete the report of his work in the Chesapeake basin during the previous year. In December, 1892, Mr. W. H. Abbott devoted about two weeks’ time to an examination of the fisheries of the eastern end of Lake Erie, supplementing the work done in that section during the previous year. In April, 1893, a visit was made to Baltimore and Annapolis by Mr. C. H. Stevenson, for the purpose of securing from official and private records some special data on the oyster industry of Maryland. THE INTERNATIONAL FISHERIES COMMISSION. During the last month of the fiscal year the writer was absent from Washington on duty connected with the work of the International Fisheries Commission. The following orders from the Commissioner, dated June 1, 1893, indicate in a general way the purpose of the Com- mission and ke wr Hees connection therewith : Mr. Richard Rathbun, assistant in charge of the Division of Scientific Inquiry, having been appointed by the President as the representative of this Government in the matter of conducting certain investigations in the waters contiguous to Canada and the United States, as called for by the agreement of December 6, 1892, between the United States and Great Britain, this work to be carried on siar etal by the United States Fish Commission and the Department of Fisheries of Canada, you are hereby detailed, at the request of Mr. Rathbun, to cooperate with and assist him in the prosecution of theseinquiries. The plans for the work will be duly prepared by Mr. Rathbun, and you will follow out such parts of them as he may desire. Youare ee - *% REPORT OF COMMISSIONER OF FISH AND FISHERIES. 65 hereby authorized to make such trips as may be necessary in connection with this detail, but will at the same time maintain a close supervision over the office of your division, returning to Washington from time to time, as occasion may require. Pursuant to these instructions, on June 1 the writer accompanied Mr. Rathbun to New York, where Dr. William Wakeham, the Canadian commissioner, and Mr. R. N. Venning, his assistant, were met. The party then proceeded to Boston, Woods Hole, Provincetown, North Truro, Wellfleet, and Gloucester, interviewing the fishermen and anak- ing observations on the fisheries, especially the mackerel fishery. On June 23 the writer returned to Washington and remained there until the close of the fiscal year. Reference is elsewhere made to the inquiries of the field force of this division addressed to some of the subjects covered by the investiga- tions of the International Fisheries Commission. REPORTS ON THE FISHERIES. During the year the reports on the statistics and methods of the fisheries issued by this Commission and emanating from this division covered three coast sections having important fishery interests. One of the Great Lakes, whose fisheries had recently received much attention, was made the subject of a special paper, and a report dealing chiefly with ichthyological matters, but containing many references to the commercial fisheries of an important region in one of the South Atlantic States, was presented. Following are the full titles of the papers and brief synopses of their contents: Report on the Fisheries of the New England States. (Bulletin, 1890.) This is one of a series of papers emanating from this division, largely statistical in their nature, in which the commercial fisheries of the different seographical divisions of the coast and lake States are consid- ered. The paper is based entirely on original field work of the division alluded to ina previous report. In the scope and detail of the statistical matter this article is more comprehensive than any paper hitherto issued on the fisheries of the region. This opportunity will be improved to call attention to an error of some importance which appears in the printed report, but which was discovered too late to secure its correction. In the tables for Massa- chusetts the following figures are given for the number of fishermen of different nationalities on the fishing vessels of the State: United States, 7,911; British Provinces, 1,157; other countries, 1,692; total, 10,760. In Essex County, which includes the important city of Glou- cester, the vessel fishermen shown in the tables number 5,729, of whom 5,133 are given as citizens of the United States, 298 of the British Provinces, and 298 of other countries. Through a clerical error a relatively small number of foreign fishermen was thus accredited to Hssex County, the correct figures for which were 3,679 Americans, 1,368 British Provincials, and 682 other foreigners. The amended figures F. R. 93 5 66 REPORT OF COMMISSIONER OF FISH AND FISHERIES. for the entire State are: 6,457 Americans, 2,227 British Provincials, and 2,076 other foreigners. The attention which the subject of the person- nel of the United States fishing marine has from time to time received makes it advisable to give prominence to this error and correction. Report on an Investigation of the Fisheries of Lake Ontario. (Bulletin, 1890.) This paper is based on an inquiry conducted by the writer in August and. September, 1891, into the fisheries of Lake Ontario, and is pre- liminary to an account of the fishing industry of this lake which will appear in a general report on the entire Great Lakes basin. Owing to the interest which attaches to the subject of the preservation, protec- tion, and propagation of the fishes of the lake, it was thought proper to expedite the publication of the results of the investigation. A Statistical Report on the Fisheries of the Gulf States. (Bulletin, 1890.) Of all the coastal regions of the United States none has been less known as regards its fishery interests than the States bordering on the Gulf of Mexico. No complete account of the fishing industry had been printed for more than a decade, and the actual condition and needs of the various branches of the fisheries, many of which are peculiar to this section, were entirely unknown. This paper, based on investiga- tions made in 1890-91, mentioned in the previous report of the division, contains complete statistics of the fisheries of each State, together with descriptive text and comparisons with 1880. Report on the Fisheries of the South Atlantic States. (Bulletin, 1891.) This paper contains a detailed statistical account of the important coast and river fisheries of North Carolina, South Carolina, Georgia, and eastern Florida, together with explanatory and descriptive text. In a special chapter the fisheries are considered by river basins, and full statistical data are presented for each important stream. The value of the paper is enhanced by the addition of 82 plates representing all the important and most of the rarer food-fishes of this region. The basis for this report is an original field investigation carried on by this division in 1890 and 1891. Report on a Collection of Fishes from the Albemarle Region of North Carolina. (Bulletin, 1891.) This paper is based on an inquiry made during the last fiscal year and outlined in my previous report on the division. The physical features of the waters in which collections were made are described, the fish found in the different localities are listed, and notes are given on their habits, abundance, ete. While primarily a contribution to a knowledge of the fish fauna of the region, much information regarding the com-— mercial fishes is presented. AS in previous years, a considerable amount of statistical and descrip- tive matter has been specially prepared for State authorities and other persons. In October a statistical and descriptive report on the fish- eries of North Carolina, based on the field work of the division, was REPORT OF COMMISSIONER OF FISH AND FISHERIES. 67 prepared for the board of World’s Fair managers of that State. In January tables showing the extent of the fisheries of Maryland and Virginia were, by request, forwarded to Mr. S. G. Brock, chief of the Bureau of Statistics of the Treasury Department. For Mr. J. B. Baylor, of the United States Coast and Geodetic Survey, a statement was prepared in December showing the output of the oyster fishery of Maryland, Virginia, North Carolina, South Carolina, Georgia, and eastern Florida. In November a series of very detailed tables cover- ing the oyster industry of Maryland was forwarded to Mr. B. Howard Haman, who had requested this information in behalf of the Baltimore Board of Trade and the State bureau of labor statistics. Statistics of the fisheries of Ohio were furnished to Hon. Daniel J. Ryan, of the Ohio board of managers of the World’s Fair,in July. Numerous other requests for data were also received, and complied with when the interests of the office would permit. NOTES ON COMMERCIAL FISH AND FISHERIES. Continuing the practice which has been followed in previous reports of the division, attention will be here drawn to some features of the commercial fisheries which seem of sufficient interest and importance to warrant mention. These notes have been furnished to the Commission by its agents and correspondents or are suggested by the discus- sions in the public prints. Among the branches referred to are the mackerel fishery, the whale fishery, and snapper fishing on the Bank of Campeche, the last named possessing great interest. Other fisheries that attracted more or less attention during the year and are fully dis- eussed in the regular reports of the Commission are the salmon fishery, the fur-seal fishery, and the Pacific cod fishery. POMPANO AND SPANISH MACKEREL IN CHESAPEAKE BAY. The pompano (Trachinotus carolinus) is of constant occurrence in the lower Chesapeake, but rarely appears in great abundance. The bay represents the northern limit of commercial fishing for this fish. In 1891 there was a remarkably numerous run of pompanoes in that part of the bay adjacent to its mouth. According to Mr. J. KE. N. Sterling, of Cape Charles City, Va., the catch with pound nets and seines on the shores of Northampton County alone was between 20,000 and 25,000 pounds. The inquiries of the agents of the office disclosed a yield of 93,760 pounds in the Chesapeake, with a value to the fisher- men of $9,520. In the following year the catch was much less, the Northampton County fishermen taking less than 5,000 pounds, according to Mr. Sterling, although there was said to be a large quantity in the bay which kept offshore out of reach of the nets. The lower Chesapeake is now the most important fishing-ground for Spanish mackerel, although its productiveness is much less than formerly, owing, it is supposed, to the capture of large quantities of fish prior to or during the spawning season. The principal part of the : tt ne 68 REPORT OF COMMISSIONER OF FISH AND FISHERIES. catch is taken with pound nets set on the two sides of the bay near its mouth. According to the statements of Mr. Sterling, the yield in 1892 was but little more than half that of the previous season. The fish were probably twice as large, however, as in 1891. As was the case with the pompano, there appeared to be large schools of mackerel out in the bay, but they did not come within reach of the nets. Mr. Ster- ling states that nearly all the fish taken in the first part of the season, or up to July 4 or 5, were fully ripe; and sometimes several hundred would be brought in during a single day, all of which would contain ripe spawn. SNAPPER FISHING ON CAMPECHE BANK. In the division report for 1892 mention was made of the preliminary steps in the establishment of a fishery for red snappers and other fish on Campeche Bank, lying about 600 miles off Galveston, in the Gulf of | Mexico. The Galveston Fish Company, organized to prosecute the fishery under the liberal regulations provided by the Mexican Govern- ment, has furnished a history of the fishing operations, from which the following account has been prepared: During the year 1892 some experimental fishing was done with a view to ascertain the probable yield of the fishing-grounds on Campeche Bank. The success of the trials led to the establishment of a regular fishery. Early in January, 1893, three welled-smacks were placed on the bank, with headquarters at Alacran Reef; these were the schooners Estella, of 36.64 tons, Caro Piper, of 28.32 tons, and Storm King, of 41.20 tons. These were manned by crews of 8 to 12 fishermen. A steam vessel, carrying 11 men, was employed to transfer the catch from the smacks to the distributing point. The principal fishes taken were the red snapper (Lutjanus blackfordt), the red grouper (Hpinephelus morio), the warsaw or black grouper (E. nigritus), sometimes called jewfish, and the jewfish (Promicrops guasa), also known as the warsaw and called junefish by the Galveston Fish- ing Company. The red snappers greatly predominated in abundance, constituting more than three-fourths of the catch. They weighed from 3to 20 pounds, large fish being verynumerous. The red groupers ranked next tothe snappers in abundance. They weighed on an average above 8 pounds. Warsaws and jewfish constantly figured in the catch, but were of little commercial value. They are large fish, and specimens of the latter were taken weighing 300 pounds. The fishing-grounds frequented by the vessels lay between Alacran Reef and Arenas Cays. Fishing was done in water 40 to 60 fathoms deep. The fish were taken with hand lines, baited with fresh red snap- per or grouper caught on the grounds. At times they would bite at almost anything, following the hook to the surface of the water, but on other occasions they became more wary and would take only fresh bait, Spanish mackerel being the most effective. Re REPORT OF COMMISSIONER OF FISH AND FISHERIES. 69 Owing to the great depth from which the fish came, it was found impossible to keep them alive in the shallow wells pending the arrival of the steamer. Consequently, as soon as caught, they were packed in ice whole and sent to Galveston in that condition. At Galveston they were sold whole or dressed, as the customers desired. Krom that place shipments were made in ice to Chicago, New York, and Denver. The fish, delivered on board the cars or boats, brought 4 to 7 cents ¢ pound, varying with the condition in which sold. Fish were very abundant at all times, and easily caught with the proper bait. As many as 20,000 pounds were taken in one day by the three smacks. Between January 21 and May 6 ten trips were made to Galveston by the steamer, and 367,808 pounds of fish were landed from the fishing-grounds, of which 321,056 pounds were red snappers, 41,412 pounds groupers, and 5,340 pounds other fish. The largest fare was brought in April 1, consisting of 51,452 pounds, of which 46,418 pounds were red snappers. The dates and detailed figures for each trip are given in the follow- ing table: Table showing the quantities of fish caught on Campeche Bank, Gulf of Mexico, and landea at Galveston, Tex., in 1893.

The following comments on the success of this venture and additional notes on the fishery have been supplied by Mr. F. A. Walthew, the president of the company: No doubt our plan for bringing these fish to this market in large quantities would be interesting, and I take pleasure in giving a short history of the venture, which has, unfortunately, not proven a success financially. We adopted, as we thought, one of the best plans for bringing large quantities of fish here. We stationed at the Cay of Alacran three fishing smacks manned by 12 meneach. These smacks were supplied with sufficient ice to store the fish caught during the steamer’s run from that point to Galveston and return. We thought in this way that we could every week bring to this port not less than 40,000 pounds of fish. Doubtiess we would have been successful in this had not circumstances been against us and misfortunes overtaken us. The intense heat in that latitude and the delay of the steamer in arriving there caused us to lose thousands of pounds of fish, and necessarily detained the steamer until a sufficient quantity could be caught to complete the cargo. 70 REPORT OF COMMISSIONER OF FISH AND FISHERIES. You will notice in our report that the steamer made only one trip in January, two in February, three in March, and three in April. This was the best we were able to do, and, although the fish are there in abundant quantities, the difficulty in catching and bringing them to this market with the attending expenses made it impossible for us to continue the business without a heavy loss. I do not know whether the plan would have been a success under more favorable circumstances or not, but I hardly think it would, as we found it a very difficult matter to obtain the services of men who would remain there and fish. The island of Alacran is situated about 500 miles due southeast from Galveston. A concession to this island was granted us by the Mexican Government for five years, for the purpose of storing fish and ice, transferring fish, etc., in fact, for any purpose appertaining to the catching and handling of fish. I beg to inform you that fish are there in an abundant supply, and are no trouble to catch. I believe the Campeche Bank is the home and breeding-ground of the deep-sea fish of the Gulf ot Mexico, and there is no time of the year when fish can not be caught there, even when they have left all other banks on the coast of Texas and Florida. No doubt there is a vast unexplored field there, and enough fish could be caught in one year to supply the entire United States. The fish were so numerous that they frequently would come to the surface of the water and the sea be fairly alive with red snappers and groupers. At such times they will snap at anything, but in certain seasons they appear to become dainty and will only bite at fresh bait, Spanish mackerel being their favorite. TERRAPIN CULTURE. The office is in receipt of numerous inquiries concerning the feasi- bility and methods of terrapin culture. The increasing searcity of the diamond-back terrapin (Malaclemmys palustris) in most of the States of the Atlantic seaboard has resulted in attracting more attention to this valuable product than was ever before given, and the necessity for preserving the animal from extinction and of putting it on the market at a price which, while remunerative, will, nevertheless, be reasonable, has suggested to many people the desirability of attempting to resort to artificial means for maintaining the supply. The almost fabulous price now received for large terrapin is also a strong incentive, not only to fishermen, but also to people of means, to engage in the industry. Sixty dollars a dozen for “count” terrapins is not an unusual price in the past few years, and it is thought by dealers and others that in a short time, under present conditions of supply and demand, the price will advance to a much higher figure. The substitution of inferior kinds of terrapin has occurred, as might naturally be expected; the principal substitute is a fresh-water species known as the red-bellied terrapin or slider (Pseudemys rugosa). The Fish Commission has made-no direct attempts to propagate ter- rapin, but has, through its field agents, kept well informed concerning the experiments of. private individuals, and has watched with interest the results of their efforts. A number of correspondents in the Middle and South Atlantic States have established terrapin farms, but suffi- cient time has not yet elapsed to fully demonstrate the feasibility of rearing terrapins for market from the egg. a REPORT OF COMMISSIONER OF FISH AND FISHERIES. 71 The principal drawbacks in the artificial rearing of terrapin are the extremely slow rate of growth of the animals and their failure to engage in the reproductive process in captivity unless the conditions of water, marsh, shore, and food are suitable. The eggs, once laid, are extremely hardy and require no attention from the hands of the calturist, pro- vided they are deposited in the proper place. THE WHALE FISHERY. Comparing the results of the whale fishery in 1892 with those in recent years, it appears that the season was fairly successful. This was, due in a large measure to the high prices commanded by the whale products, the average value of whale and sperm oil being 424 and 674 cents per gallon, respectively, and that of bone $5.35 per pound. The whaling fleet consisted of 95 vessels, of which 48 had head- quarters at San Francisco, 33 at New Bedford, 7 at Provincetown, 1 at Edgartown, 1 at Boston, and 1 at New London. The catch in the Atlantic Ocean was about the same as in 1891, and the season was considered satisfactory. The product consisted of 6,910 barrels of sperm oil, 1,775 barrels of whale oil, and 6,935 pounds of bone, the whole having a value of $201,895. One vessel, the bark A. hk. Tucker, of New Bedford, fished in Hudson Bay, taking 276 barrels of oil and 4,000 pounds of bone. The success of the vessels fishing out of San Francisco was marked, and was chiefly due to the abundance of whales in the Arctic Ocean about 300 miles east of Point Barrow, where only small catches had been made for nearly twenty years. About the middle of August, the fleet reached Point Barrow, thence 2 sailing and 9 steam vessels cruised to the eastward, joining the steamer Mary D. Hume, which had spent the winter at Herschel Island, in the mouth of the Mackenzie River. Within about a month these vessels took 116 bowhead whales in this region, and then sailed westward to join the remainder of the Arctic fleet in the vicinity of Herald Island, where 90 additional whales were obtained. Twenty-two vessels that cruised on the grounds off Kadiak and Okhotsk Sea took 27 bowhead whales. The total number of whales secured by the San Francisco fleet was 242. The oil and bone extracted from these consisted of 11,610 barrels of whale oil, valued at $155,429; 1,845 barrels of sperm oil, valued at $39,230; and 362,950 pounds of bone, valued at $1,941,783; the total stock of the west coast fleet being $2,136,442, The most prominent feature of the whale fishery prosecuted on the Pacific coast was the conclusion of the voyage of the steamer Mary D. Hume in 1892, after the most successful whaling trip on record. The vessel sailed April 19, 1890, passed the winters of 1890-91 and 1891-92 in the ice at Herschel Island, and returned to San Francisco Septem- ber 29, 1892. The vessel killed 12 whales in 1891 and 26 in 1892, which hada value of about $400,000. The captain is reported to have shared between $30,000 and $40,000, and each of the crew $1,800 or $2,000. . 12 REPORT OF COMMISSIONER OF FISH AND FISHERIES. SOME RESULTS OF ACCLIMATIZATION. The supply of shad on the Pacific Coast, to which attention has been drawn in several reports of the Commission, continues to increase, and the augmentation in the catch has been attended with such a marked reduction in the price to the consumer that the fish has been placed within the reach of every one, the retail value being much less than on the Atlantic Coast. Within a few years the shad has thus not only been acclimatized along the entire coast south of Alaska, but has become one of the cheapest fish of the region. The inquiries of the Commission disclosed a catch of over 700,000 pounds in 1892, having a value to the fishermen of over $20,000. : Over 50,000,000 shad fry have been planted in the streams of the Mississippi Valley without producing any marked results. The waters of this region are not so well adapted to shad as those of the Atlantic and Pacific coasts; the rivers are usually extremely muddy and subject to heavy freshets; the headwaters of the main streams are too remote from salt water to permit the shad to make the annual migration which occurs in the coast rivers; and except in the shorter rivers of the Gulf Coast, the shad would have to remain permanently in the streams. Instances of the capture of full-grown shad in some rivers of the Gulf Coast have from time to time been recorded. Twoadditional references may be mentioned: Under date of March 2, 1893, Mr. B. F. Sutter, of Montgomery, Ala., wrote that he had a shad, taken in the Alabama River, weighing 4,5; pounds; that the shad were planted in the river about six years before and are growing very fast; and that they are finely flavored fish. Mr. S.D. Ingram, of Pass Christian, Miss., stated in a letter dated June 3, 1893, that some shad had been taken near that place in the spring of that year. The increase in striped bass in California is relatively as great as that in shad. The fish is now one of the most highly esteemed products of the west coast fisheries, and the high prices which prevailed a few years ago have been so reduced by the larger catches that the fish is generally available for food, although still ranging much above salmon in value. The distribution of the striped bass is still restricted to Cali- fornia. The yield in 1892 was about 50,000 pounds, valued at over $6,000. The following brief account of the history and results of the intro- duction of shad and striped bass to the Pacific Coast was prepared by the present writer, with the Commissioner’s approval, and printed in the issue of Science for August 18, 1893. The catch shown, embodying the preliminary returns, differs somewhat from the actual figures given elsewhere: FISH ACCLIMATIZATION ON THE PACIFIC COAST. Few experiments in fish-culture have been ecomomically more important and suc- cessful than those which have been conducted by the United States Fish Commission with reference to the Pacific Coast. Coincident with the propagation of native fishes, the introduction of non-indigenous species has been undertaken, with results that sf Pye REPORT OF COMMISSIONER OF FISH AND FISHERIES. 73 have been extremely gratifying to fish-culturists, and perhaps more striking than any previously obtained in this or any other country. Among the fishes inhabiting the rivers and coast waters of the Atlantic Slope, none is better known, more important, and more highly esteemed than the shad (Clupea sapidissima) and the striped bass or rockfish (Roceus lineatus), the former being a food-fish, pure and simple, the latter combining a gamey disposition with excellent food qualities. These fish are anadromous, entering the fresh water for the purpose of spawning and passing a large part of the year at sea or in the salt water. Atten- tion will be called to the experimental introduction of these fishes to the west coast, although several other important food-fish, among them the black bass (Micropterus salmoides) and catfish (Ameiurus nebulosus) might also be mentioned in this connection. The introduction of shad fry to the west coast was first undertaken as long ago as 1871, when 12,000 young fish were deposited in the Sacramento River, under the auspices of the California Fish Commission. After that the experiment was taken up by the United States Fish Commission and carried on until 1886, during which time 609,000 young shad were placed in the Sacramento River, 600,000 in the Willa mette River, 300,000 in the Columbia River, and 10,000 in the Snake River. Two or three years after the first fish were planted a few more or less mature examples were obtained in the Sacramento River; as additional deposits were made, the number of marketable fish began to increase, and the fish gradually distributed themselves along the entire coast of the United States north of Monterey Bay, until finally they have come to rank next to salmon in abundance among the river fishes of the west coast. The United States Commissioner of Fish and Fisheries, in his annual report for 1887, speaking of the small plants of shad fry made in the Sacramento River at Tehama, says: From these slender colonies, aggregating less than 1 per cent of the number now annually planted in our Atlantic Slope rivers, the shad have multiplied and distributed themselves along 2,000 miles of coast, from the Golden Gate of California to Vancouver Island in British Columbia. They are abundant in some of the rivers, common in most of them, and occasional ones may be found everywhere in the estuaries and bays of this long coast line. Prior to our experiments on the west coast it was a dictum of fish-culture that fish planted in a river would return to it when mature for the purpose of spawning. The result of these experiments has been to demonstrate that this instinct of nativity, should it really exist, is in this case dominated by other influences, which have dispersed the shad planted in the Sacramento widely beyond the limits which we had assigned to them, and in the most unexpected direction. The cause is probably to be sought in the genial influences of the Japan current, which brings the warmth of equatorial Asia to temper the extremes of Arctic climate on the southern shore of the Alaskan Peninsula, and, thence sweeping to the south, carries tropical heats to the latitude of San Francisco. Repelled on the one hand by the low temperature of the great rivers and fringe of coast waters, and solicited on the other by the equable and higher temperature of the Japan current, the shad have become true nomads, and have broken tie bounds of the hydro- graphic area to which we had supposed they would be restricted. Following the track of the Asiatic current, and finding more congenial temperatures as they pro- gress, it is not unreasonable to expect that some colonies will eventually reach the coast of Asia and establish themselves in its great rivers. Shad are now found in greatest numbers in the Sacramento and Columbia Rivers, where they are of considerable economic value. Owing to the fact that very little apparatus specially adapted to their capture is employed, no correct idea of their actual abundance in a given stream can be formed. Nearly all the shad thus far taken have been obtained in nets operated for salmon or other fish, shad being only an incidental element inthe catch. The price received by the fishermen is a good criterion of the abundance of the fish. When first taken, shad brought as much as $1.20 apound; in 1892 the value in many places was only 2 cents a pound, and in the Columbia River at one period the catch was so large and the price so low that the fishermen did not go to the trouble of marketing the fish caught. The average price on the coast has declined in the past four years from 10 cents per pound in 1889 to 4 cents in 1892. 74 REPORT OF COMMISSIONER OF FISH AND FISHERIES. An inquiry conducted by the United States Fish Commission in 1892 placed that bureau in possession of information showing the extent of the shad fishery in every river of the Pacific States. It was ascertained that in the year named 660,000 pounds of shad were marketed, the value of the same to the fishermen being about $27,000. Reports received during the present year indicate a catch of perhaps a million pounds, and it seems reasonable to anticipate a steady increase in the production with the improved facilities for shipment and the growing demand for fresh fish in the rising towns adjacent to the coast rivers. A careful estimate places the total value of the shad catch on the Pacific Coast to date at $145,000, representing over 3,000,000 pounds, while the aggregate outlay for all purposes connected with the introduction of the fry was less than $4,000. This is certainly a satisfactory invest- ment of the people’s money. The absence of a special scientific inquiry precludes the possibility of chronicling the changes which have probably been wrought in the habits of the shad as a result of the changed physical surroundings, thermic conditions, enemies and food supply. It may be noted, however, that the characteristic habit on the east coast of periodi- cally ascending the rivers for the purpose of spawning, and of returning, after the completion of that process, to the open sea, where the principal part of the life of the fish is spent, appears to be considerably modified, in California, at least, where in certain bays and estuaries the shad is found in greater or less abundance during every month in the year. The evidence at hand indicates a condition prevailing in the littoral and fluvial waters of the Pacific Coast that is very favorable to the growth of the shad. It is not unusual to take examples considerably larger than any ever seen in the eastern rivers. The average weight of the shad caught on the Atlantic Coast is under 4 pounds, and the capture of fish weighing 7, 8, or 9 pounds is extremely rare. In California, however, it is not uncommon to secure shad weighing 8 or 10 pounds, and reports have been made that 15-pound individuals have occa- sionally been obtained in salmon nets. Of scarcely less consequence than the actual results of shad introduction on the west coast is the important bearing which the success of the experiment must have in determining the outcome of artificial propagation in regions in which it is not possible to distinguish with satisfactory accuracy the natural from the artificial con- ditions. If these far-reaching, and no doubt permanent, results attend the planting, on few occasions, of small numbers of fry in waters to which the fish are not indige- nous, is it not permissible to assume that much more striking consequences must follow the planting of enormous quantities of fry, year after year, in native waters? There is no reasonable doubt that the perpetuation of the extensive shad fisheries In most of the rivers of the Atlantic Coast has been accomplished entirely by artificial propagation. On no other supposition can the maintenance and increase of the aupply be accounted for. The introduction of the striped bass was accomplished in 1879, when about 150 fish, a few inches long, taken in Shrewsbury River, New Jersey, were successfully carried across the continent and deposited at the mouth of the Sacramento River by an agent of the United States Fish Commission, cooperating with the California commission. Six or seven months later an example 8 inches in length was reported from Monterey Bay, 100 miles south of the locality where planted, and in eleven months another specimen 124 inches long, and weighing 1 pound, was caught in San Francisco Harbor. This very rapid growth indicated the special adaptability of the waters of the region to this fish. In 1882 another plant, consisting of 300 fish, was made in the same region by the California authorities. As a result of these two small deposits, the species soon became distributed along the entire coast of California; its occurrence, however, in the other States of the region has not yet been determined. 7 The history of the striped bass is similar to that of the shad. It has attained considerable commercial importance, has increased steadily and rapidly, and is generally regarded as one of the best food-fishes of the coast. It has not yet attained anything like the abundance of the shad, nor was this to have been expected from the REPORT OF° COMMISSIONER OF FISH AND FISHERIES. 75 meager plants, but there seems to be no reason to doubt that it is only a question of time when it will become one of the most prominent economic fishery products of the region, as well as a favorite object of capture by sportsmen. The largest quantities of striped bass are taken for market in San Francisco Bay with seines and gill nets. The fish are found in greatest numbers between October 1 and February 15, but occur in some abundance at all seasons. Their average weight is 8 or 10 pounds, but fish weighing 40 pounds are not scarce. ‘The estima- tion in which they are held may be judged from the market value. In 1888 the ruling price in San Francisco was #1 a pound; in 1892, owing to an increased pro- duction, it had dropped to 124 cents. The catch in the latter year was about 43,000 pounds, for which the fishermen received $5,350. The aggregate yield to date may be estimated at nearly 100,000 pounds, with a value at first hands of about $18,000. The transportation of striped bass to the Pacific being undertaken conjointly with that of a number of other fishes, it is probable that the proportional cost of intro- duction was not more than a few hundred dollars. THE MACKEREL FISHERY. The chief interest centering in this fishery during the year 1892-93 depended on the great activity which at times characterized the opera- tions of the fleet on the New England shore in 1892 and on the renewal of the southern fishery in the spring of 1893. The fishing season which terminated in the fall of 1892 was, on the whole, the most successful since 1888. The number of vessels constitut- ing the fleet was about 200. The catch of salt mackerel was reported to be about 47,000 barrels, against 38,000 barrels the previous year. The quantity of fresh mackerel taken was about 40,000 barrels. The total value of the catch was about $1,000,000. Early in the season a large body of fish was found on the Nova Scotia shore, and some profit- able fares were landed from that region. Later, fish were found in comparative abundance on the Maine coast, where the largest part of the season’s catch was obtained. In August the fish disappeared from that section and were absent during the whole of the following month. Some good-sized fares were afterwards landed from Block Island. A small fleet entered the Gulf of St. Lawrence; 15 vessels are reported to have taken about 2,200 barrels of salt mackerel in that body of water. After a lapse of five years the southern spring mackerel fishery was resumed in 1893 and constituted one of the most interesting features of the New England fishing industry during that year. The law which prevented the prosecution of this fishery between 1888 and 1892, inclu- Sive, was one of the very few legislative measures affecting the fisheries which had been enacted by the United States Congress, and as such it attracted much attention. The full text of the so-called close-time mackerel law was as follows: An act relating to the importing and landing of mackerel caught during the spawning season. Be it enacted by the Senate and House of Representatives of the United States of America in Congress assembled, That for the period of five years from and after the first day of March, eighteen hundred and eighty-eight, no mackerel, other than what is known as Spanish mackerel, caught between the first day of March and the first day of June, inclusive, of each year, shall be imported into the United States or landed upon its shores: Provided, however, That nothing in this act shall be held to apply to 76 REPORT OF COMMISSIONER OF FISH AND FISHERIES. mackerel caught with hook and line from boats, and landed in said boats, or in traps and weirs connected with the shore. Src. 2. That section forty-three hundred and twenty-one of the Revised Statutes is amended, for the period of five years aforesaid, so as to read before the last sen- tence as follows: ‘ This license does not grant the right to fish for mackerel, other than for what is known as Spanish mackerel, between the first day of March and the first day of June, inclusive, of this year.” Or in lieu of the foregoing there shall be inserted so much of said period of time as may remain unexpired under this act. Src. 3. That the penalty for the violation or attemped violation ef this act shall be forfeiture of license on the part of the vessel engaged in said violation, if a vessel of this country, and the forfeiture to the United States, according to law, of the mackerel imported or landed, or sought to be imported or landed. Sec. 4. That all laws in conflict with this law are hereby repealed. Approved, February 28, 1887. On the approach of the usual time for starting on the southern cruise for mackerel, a large fleet of vessels from Gloucester, Portland, and other New England ports sailed for the grounds off the Virginia and Dela- ware coasts, where fish were sighted in due time. Large schools were reported from time to time, but they consisted mostly of small indi- viduals which were turned loose when caught. A few vessels made satisfactory fares which realized good prices and encouraged others to continue the search for fish. The season closed, and the fishery passed into history generally regarded as a failure. A few thousand barrels of fresh mackerel were landed and a few hundred barrels of salt fish were saved, but many of the vessels failed to secure any fish whatever, and only a few paid expenses. The season was remarkable for the extremes of sizes represented by the fish landed.» Some of the fares consisted of fish that averaged considerably larger than had been taken south durmg any recent years, while a cargo of 25 barrels of mackerel brought into New York was made up of smaller fish than were ever before sold in that market, 2,500 to 3,000 being required to fill a barrel. THE NEW ENGLAND GROUND-FISH FISHERIES. The important bank fisheries for cod, haddock, hake, cusk, and hali- but were followed with the usual vigor during the year, and the catch, on the whole, was fully up to the average in recent years, while the price and demand were regarded as all that could be expected. For several years the Grand Banks had shown a marked decrease in the abundance of cod, resulting in many broken voyages and consider- able pecuniary loss to fishermen and owners. A much smaller fleet than usual was consequently sent out in 1892, and only about a dozen vessels from Provincetown, Mass., and Bucksport, Me., in addition to the comparatively large fleet from Gloucester, Mass., have represented the United States on these banks. Contrary to the general expecta- tion, in 1892 cod were again found in great abundance on the Grand Banks. Nearly all of the Gloucester fleet made two trips, returning each time with full fares, and the aggregate catch was larger than during any year since 1887. Halibut were found in about their usual REPORT OF COMMISSIONER OF FISH AND FISHERIES. 7 numbers. While during the past three years there was a slight ten- dency toward an increase in numbers, the fish are much scarcer than they were eight or ten years ago. Georges Bank, the most celebrated fishing-ground off the coast of New England, continues to be the chief resort for the large fleets hail- ing from Gloucester, Boston, Provincetown, and other ports, especially those vessels engaged in supplying the increasing demand for fresh salt-water fish. During the spring the catch of cod was light, but in the fall the fish were more abundant. Haddock were more numerous than for many years. Many vessels, returning after a few days’ fishing, brought from 80,000 to 100,000 pounds of fresh fish, chiefly haddock. The market was often overstocked with haddock, and the surplus had to be cured. A somewhat interesting phenomenon attended the operations of the vessels frequenting Georges Bank. During the great abundance of haddock on Georges Bank cod were very searce on the same grounds. This, in the opinion of many fishermen, was owing to the habit of throwing the offal overboard, thus covering the feeding-grounds and driving the cod away, although why the haddock were not also affected by the offal is not clear. During the scarcity of cod on Georges they were unusually plentiful on Cashes Bank and Jeffreys Ledge, adjoining ' grounds. REPORT ON THE PROPAGATION AND DISTRIBUTION OF FOOD-FISHES. By S. G. WortTH, Acting Assistant in Charge. INTRODUCTION. In the Report proper of the Commissioner, pp. 6 and 14, reference may be found concerning the appointment of Dr. Tarleton H. Bean as assistant in charge of the Division of Fish-Culture, and also Dr. Bean’s subsequent appointment as United States Fish Commission represent- ative at the World’s Columbian Exposition, Chicago, Ill. The per- formance of duties incident to the Exposition caused Dr. Bean to be absent from the Washington office after January 15. Duties devolving upon the acting assistant, additional to those of the office of the Division of Fish-Culture, consisted in the installation of shad-hatching operations at Battery Island Station, the supervision of Central and Bryan Point stations, the preparation of artificial fish eggs for illustrating the hatching of eggs of a semi-buoyant and floating nature at the World’s Fair, Chicago, the adaptation of a baggage car for transporting fishes in water oxygenized on a new plan, namely, with air circulation, and assisting the Commissioner in preparing for and conducting his experiments for solving in advance the value of salt water wholly artificial in character as the medium for exhibiting marine animals and plants in a live state at Chicago. There was also large expenditure of time and individual labor as a member of the civil service board of examiners of the Fish Commission. STATION OPERATIONS. The stations operated during the year were: Schoodic Station, Maine. Wytheville Station, Virginia. Craig Brook Station, Maine. Put-in Bay Station, Ohio. Green Lake Station, Maine. Northville Station, Michigan. Gloucester Station, Massachusetts, Alpena Station, Michigan. Woods Hole Station, Massachusetts. Duluth Station, Minnesota. Delaware River Station (steamer Fish Quincy Station, Illinois. Hawk). Neosho Station, Missouri. Battery Island Station, Maryland. Leadville Station, Colorado, Bryan Point Station, Maryland.

The fiscal year opened with 50,000 landlocked salmon in the rearing- troughs, the hatching of the April preceding. The losses amounted in July to 106 and in August to 1,546. Late in August about 48,000 were liberated in Grand Lake andits outlet. In September all property was stored, the services of employees discontinued, and subsequently such part of the apparatus as was deemed of value transferred to the Craig Brook Station, work being permanently stopped, and further operations with the landlocked salmon conducted at Green Lake Station. CraiG Brook STATION, MAINE (CHARLES G. ATKINS, SUPERINTENDENT), Some minor but important constructions during thé year made this station almost perfect for the hatching and rearing of salmonide. Atlantic salmon.—The most important departure in fish-cultural methods was in the disposition, widely apart on the lawn, of stands of rearing-troughs fed by water of different origin, the object being to prevent the recurrence of a wholesale spread of disease like that of the preceding year, and, in the event of the reappearance of unfavorable _ symptoms, to determine, if practicable, the underlying cause and the - measures favorable to its eradication. No unfavorable developments Peake, occurring, the seat of former attacks remained undiscovered. The collection of eggs was again effected, in cooperation with the authorities of the State of Maine. There had been purchased in June, 1892, and confined in the inclosure at Dead Brook, 222 adult fish, of which number 170 were available in October and November, 108 being females. The result in eggs was 1,108,500, of which 1,025,000 were alive in February when division was made, the portion of the Maine commissioners being 565,000 and that of the United States 460,000; of these latter, there were shipped as follows: 7 : Neo. of Date To whom shipped. eges Jan.25 1893..| E.

The Maine commissioners being desirous of devoting a portion of their quota of eggs to further stocking the Penobscot River, arrangements were effected for developing and hatching at the station as many of their stock as 200,000, they providing the additional labor and supplies requi- site to meet the increased demands. These authorities subsequently donated 84,000 fry to the United States. Forty-three salmon, resulting from eggs taken November, 1887, yielded in November, 1891, about 12,000 eggs, and in November, 1892, produced about 23,000 eggs. As the parent fish from the fry stage had been continuously held in fresh-water ponds of the station, thereby becoming > 80 REPORT OF COMMISSIONER OF FISH AND FISHERIES. acclimated and successfully reproducing their kind, the experiment is not without interest. A portion of the 23,000 eggs perished and 10,000 were shipped to the Green Lake Station, those remaining being applied to hatching. The resulting fry, estimated at 5,000, were represented by 2,000 survivors June 30,1893. Of the total of 2,010 surviving Atlan- tic salmon on hand as fingerlings June 30, 1892, from the hatching of 305,000 eggs in April of that year, 1,100 were from eggs of the aceli- mated parents, and of the 1,448 subsequently liberated in November, 696 were of this kind. At the date of the liberation referred to, as many as 500 were remaining as a reserve, but these were reduced to 156 by the following June. Landlocked salmon.—From fish reared 9,300 eggs were taken in November, and from wild fish captured from Toddy Pond 4,200 were secured. It is believed that the spawning fish in Toddy Pond were the large ones liberated from the Craig Brook Station in the spring of 1892. Egg losses were rather large. Brook trout.—Fourteen thousand eggs were taken from fish reared in station ponds. The hatching is shown in tabular statement. Rainbow trout.—The thirty adult fish held in ponds were reared at the station, having been hatched in 1889 from eggs received from the Northville Station, Michigan. In the spring of this year they, for the first time, evinced a tendency to spawn, eggs being taken March 15 and 16 to the number of 10,000. The eggs were inferior, and during the year there were seventeen deaths among the brood stock. The statement below, based on close estimates, represents eggs of various species employed in hatching, and shows the results up to.a period when all except the rainbow trout were taking food: a Results in fry.

The water used at the hatching-house flows through a conduit having connection with the brook at a point above the sources of the springs. Pond B, referred to in table, being situated below the hatchery, receives a mixture of brook and spring water. It is a small pond, which, till May, 1893, accommodated the Atlantic salmon previously referred to as having been acclimated. The north stand of rearing-troughs, out- door situation, is fed from above the hatchery, receiving commingled waters of brookand springs. Alamoosook Lake, a body of fresh water about 5 miles long, on the bank of which the station is located, became closed by ice formation December 12, and was not again open until May 1. On February 10 the ice measured 284 inches, and was crossed by teams December 25 and April 8. Early in December exposed water conduits were protected by a covering of hay, boards, and evergreen brush, and toward the end of the month the two ice-houses were filled from the lake. The observations on which the table is based were made daily, at 7 a. m. and 2 p. m., omissions in June being incident to shutting off water for repairs: i FE.

H. Buck AND SEYMOUR BOWER, SUPERINTEN- DENTS). This station being new and incomplete, the year opened with improve- ments in progress. Mr. H. H. Buck was in charge until August 31, his resignation having been tendered in April, but remaining unacted upon owing to delay attending the selection of an efficient successor. He was followed by Seymour Bower, who was appointed from the foreman- ship of the Put-in-Bay Station, Ohio, and arrived for duty September 12. Mr. Bower’s services, however, being solicited by the commissioners. — of Michigan, he tendered his resignation May 8, in order to accept the superintendency of the fish-cultural operations of that State. Owing to the inconvenience of providing a competent successor, Mr. Bower’s services were retained until June 30. On his departure affairs were temporarily put under direction of the foreman, W. H. Munson. Fry resulting from the April hatching and on hand at beginning of the fiscal year, by estimate, were as follows: Landlocked salmon, 60,000; Loch Leven trout, 16,000; Von Behr trout, 10,000; total, 86,000. During July they underwent but little loss, but in August many deaths occurred. In September active measures were instituted with a view to checking the mortality. The changes were in the nature of increasing the depth of water in the rearing-troughs from 2% to 4 inches, daily cleaning with serub brushes and salt, increasing the flow of water through troughs, and more systematic and careful feeding. The num- bers, by count, in December were but 4,903 landlocked salmon, 1,805 Loch Leven trout, and 1,252 Von Behr trout. Subsequent losses were trifling, there being but 14 dead removed in the four months following. The maximum water temperature in July was 82° F., in August 709, and in September 68°. During the four months’ period just referred to there were no deaths among the 3,800 landlocked salmon hatched in April, 1891, held in the reservoirs. On May 5 the fish of April, 1892, were again counted and transferred from rearing-ponds to new earth ponds, the numbers being, landlocked salmon, 4,656; Loch Leven trout, 1,688; Von Behr trout, 1,042; total, 7,386. In April there were shipped alive to the World’s Fair by Car No. 3° 100 of each kind of trout and 300 of thesalmon; also, 200 of the salmon” 4 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 83 of 1891. Other specimens sent consisted of 9 wild adult brook trout, 4 wild adult salmon, and a small collection of smelt from Green Lake. The only fish liberated, and these by accident, consisted of 500 of the | younger salmon, which escaped into Green Lake November 16 through ‘the misplacement of a screen. On December 14 there were 19 small German carp sent to the station by Dr. W. M. Haines, of Ellsworth, and liberated in Great Brook, tributary to Green Lake. Landlocked salmon.—The salmon of Green Lake, averaging 6 pounds in weight, ordinarily spawn in the inflowing streams, but some pass ‘through the outlet and lay their eggs below in the waters of Reed ‘Branch, as was this year definitely proved. When the spawning period arrives during the seasons of drought, the affluents being low, the fish ‘will not pass up, but remain in the lake. To induce them to ascend Great Brook at such times it is necessary to resort to artificial flushing, ‘and there being facilities on the headwaters for accomplishing this, ‘success has been attained. Mountainy, the uppermost pond, 5 miles ‘distant, is used as the flushing reservoir, the system pursued consisting in opening gates about 2 p. m., creating a large flow throughout the night. ‘The rainfall in September and October having been slight, there was by ‘November 1 barely sufficient water for this purpose and the station proper. Great Brook was the only affluent affording adult fish, though in October many were seen jumping near the mouths of other inlets. Egg collections being wholly dependent on wild fish, arrangements for capture were effected in September, at which time the slat traps iin Great Brook were repaired, another obstruction being put in position ‘at the discharge of Mann Brook. Two others were located at the lower end of the lake, one just inside, for the capture of outward-moving fish, and the other in Reed Brook, about a mile below, for the capture of fish ascending. Wire screens were, in November, placed in the gateways at the discharge of the lake to prevent fish escaping. Before the screens ‘were inserted aS many as 100 young salmon from 6 to 10 inches long ywere at one time seen below the dam. The aggregate catch was 152, Great Brook furnishing 83 and the lake outlet trap 69. Of the captures at Great Brook trap, 53 were females; of those from the outlet of the lake, the females numbered 26. One salmon bearing “No. 2” tag, attached in 1890, was taken. The first capture,on September 27, consisted of two males and three females. “On October 31 the first eggs of the season, 12,000 in number, were ‘obtained. The largest success at the outlet of the lake was November 4, when 14 fish were taken, 8 of the 9 females affording 22,000 eggs of good quality. The most successful day was November 9, when 31,500 eggs were taken from fish held in the Great Brook traps. The last eggs were taken November 23, and the next day all parent fish were set free in the lake, the total of eggs for the season being 213,300. Aninspection of the stream feeding Mountainy Pond was made in October, and also that connecting Mountainy and Rocky ponds in November, to determine the presence of available spawners, but no indications were found. : 84 REPORT OF COMMISSIONER OF FISH AND FISHERIES. The eggs acquired were of superior quality, only 9,000 having been discarded by December 31, when the outlines of the embryos were clearly visible. It was anticipated that more than 200,000 would hatch, but on January 15 an unexpected death rate was encountered and its continuance for a month materially reduced the stock. A minute white spot on the egg resulted, in the course of two days, in a growth of fungus. The source of fatality is charged to careless handling in the process of picking, when the eggs were exposed to the higher air tem- perature of the room for unnecessarily long periods. On April 5 all were carefully washed, picked, and spread evenly on 81 trays, and the contents of several trays being ascertained by counting, the whole number was found to be 166,000. Hatching was observed as early as April 8, and at the end of the month no eggs remained. A subsequent table indicates the success attending the stock in the fry stage. Brook trout.—Egg collections were from wild fish taken from Wink- empaugh Brook, a tributary of Branch Pond, 10 miles distant. On October 19 two employees, provided with equipment for establishing a trap to arrest the progress of ascending fish, were dispatched to the ‘scene. The trap was at once put in place, and eleven days after 1 male and 10 females were taken, from 5 of which, then ripe, 10,000 eggs were secured, these being delivered at the station the same day. The weight of one of these fish was about 5 pounds. During one night, about the middle of November, 54 female trout were taken. The ineffective arrangement of the trap permitted nearly all male fish to escape, and this, together with injuries sustained from the cutting of minks and muskrats, and a sudden freshet, led to the unobstructed passage of probably two-thirds of all fish ascending. There were 72 females captured, a portion of which escaped before their eggs were stripped. The Winkempaugh trout are the genuine Salvelinus fonti- nalis, ranging in weight from 2 to 5 pounds, and exhibiting brilliant markings. The coliection of eggs amounted to 109,400, of which 8,500 were treated with milt of landlocked salmon without result. Besides the above, a few unproductive eggs were acquired from fish captured in the Great Brook traps. The eggs in development turned out poorly, as a result of defective fertilization, the greater portion being discarded by December, many of those remaining showing up as “ringers.” Other trout eqggs.—Egegs additional to those already mentioned were in the nature of express consignments, represented below: Date.

REPORT OF COMMISSIONER OF FISH AND FISHERIES. 85 _ Fry.—All eggs were hatched in April and the fry were in good condi- tion, except Atlantic salmon, and the parentage of this lot is mentioned -under the heading of Green Lake Station. In order to accommodate ,and successfully care for the young fish in process of rearing, it was ‘necessary to erect, in advance of more permanent constructions, a ‘temporary outdoor stand containing 46 troughs. These, with 38 half -hogsheads, arranged at the same point, and the interior troughs of the ‘hatchery, afforded 126 receptacles. The supply conduit, 7,050 feet Jong, was ventilated by the removal of boards at more than 300 points, and for still more complete aération 25 breakwaters were inserted. The ‘flow was increased to permit the employment of 15 to 25 gallons of | water per minute to each trough and tub. Four temporary ponds, to ‘receive the waste of outdoor receptacles, were among the preparations. Supplies of food, consisting principally of liver, were obtained at | Bangor instead of Ellsworth at a reduced rate of cost. The older fry ‘began feeding May 12, all others following before the end of the month. The approximate stock of fry May 31, with losses, is given below: Percent- Kind. ea Discarded. age of Oss.

It should be stated that, in the report just referred to, the statement is made that in June Mr, Davis, fish-culturist at the Green Lake Station, witnessed the killing of four landlocked salmon by a horse-leech in one of the interior hatching-troughs, the deaths occurring within a few minutes’ time.

On the breaking of the launch’s shaft, November 5, the station horse and small boats were used instead. In December the air temperature on three or four mornings dropped below zero, the water in the hatchery descending as low as 34° F., the maximum for the month being 38°. An increased flow of water through the supply conduit, as a general protection against freezing, caused overflowings and the formation of heavy icicles upon trestlings where the ravines are spanned, requiring at times much labor in cutting away the accumulations. The first snow permitting sleighing fell Jan- uary 10. Connection with the post-office was effected daily by sleigh over the ice on Green Lake after January 5, continuing until late in April, the ice being melted May 12, when steam-launch service was resumed. The air temperature in January was as low as—14°, the water in the hatchery ranging from 34° minimum to 36.5° maximum. In February one snow-fall of 27 inches occurred. In that month a temporary structure was stored with 25 tons of ice of 24-inch thickness. The April water temperature was 37.5° minimum and 46° maximum. When the ice broke up in the lake, May 6, the water rose above the station wharf, but by the end of the month it had fallen over 2 feet. The minimum hatchery temperature for May was 44°, maximum 64°, average 54.59. Toward the end of the year negotiations were pending for renting a larger boat for service on Green Lake. GLOUCESTER STATION, MASSACHUSETTS (A. C. ADAMS, MASTER OF THE SCHOONER GRAMPUS, IN CHARGE). General overhauling of the station in preparation for the winter’s operations commenced December 13, cold weather delaying this work considerably, the supply pump not being in readiness until January 10. The United States Fish Commission schooner Grampus, her crew acting | aS Spawn-takers, was employed in making egg collections. 87 Fish being scarce off Gloucester, the schooner was stationed the greater portion of the time at Kittery Point, Maine, where regular supplies of eggs of REPORT OF COMMISSIONER OF FISH AND FISHERIES, fair quality were obtained from January 13 to March 13. As usual, a small run of codfish, available for spawn-taking purposes, appeared off Gloucester in November, but fish were generally scarce here throughout the season, the few eggs obtained being from the schooner Odd Fellow. Early in January the upper harbor became filled with ice and the weather was so intensely cold that the steam condenser, the waste from which is employed to increase the water temperature, became inopera- tive on account of ice formation in the pipes. The collections from Kittery Point were obtained from vessels fishing in Ipswich Bay, the price paid for good eggs being $5 per 1,000,000. The collections were transferred to the station by messenger over the railroad, the greater part arriving in good condition. There were no eggs obtained except of the codfish, and the first ot these were secured January 14. On that date the harbor temperature was 31°, the warm water overflow from the steam condenser, available at that time, increasing the temperature in the hatching-boxes by 3°. ‘The shipments from Kittery Point in January were 12,202,000, Febru- ary 18,408,000, and March 29,200,000. The total number received was 51,584,000, of which 49,831,000 were good. The fry produced amounted to 20,142,000, these being liberated in the waters adjacent, within a few days after hatching.

This was a clear-water season until February 10, when a violent storm occurred, filling the water with sediment. There was less uniformity in the hatching of eggs and the fry were weaker than in the best seasons. The poorer quality of hatching was attributed to the low water temperature, which could not be controlled for the reason mentioned, but the larger portion of the fry were active, and the poorer lots—those which failed to straighten—were not included in the record of those distributed. Onelot of eggs, February 16, consisting of 2,000,000, pro- duced 76 per cent of fry. Alcoholic collections of eggs and embryo fishes were prepared and transferred to the general office for use at the World’s Fair. On April 17 the station was closed, Mr. HE. F. Locke, fish-culturist, being left in charge of property. 88 REPORT OF COMMISSIONER OF FISH AND FISHERIES. Woops HoLe STATION, MASSACHUSETTS (JOHN MAXWELL, SUPERINTENDENT). Operations were on the usual basis, fish-cultural work consuming about eight months of the year. A large amount of interesting and valuable material, consisting of marine fishes, crustaceans, plants, etc., was collected April 1 to June 50 for transfer to the’aquarial exhibit at Chicago. About 9,000 living animal forms were transferred, these representing 40 species. The lobsters were crated in seaweed. Large alcoholic collections were also made. Codfish.—This was a poor season for hatching codfish. On October | | 27 the Grampus was detailed to make collections of adult fish, but between the date named and December 28 the total amounted to but 41. In order that success might be secured, Mr. Vinal N. Edwards, the collector at the Woods Hole Station, was sent out as pilot, but the great draft of the Grampus prevented successful handling in shoal water, where cod were most abundant. Numerous trips were made to Block Island, Nantucket Shoals, and Browns Ledge, but fish were too scarce to afford success. Eventually a contract was entered into with private parties engaged in fishing, and by purchase 275 additional fish were obtained, a total for the season of 316. On January 1 the Grampus sailed for Gloucester, operating there the remainder of the winter. The total of eggs obtained was 2,883,000, taken December 13 to Jan- — uary 5 from 20 fish. The fry produced amounted to 850,500, a fraction over 29 per cent. It will be noted that this winter was one of unusual severity, and on January 6 a sudden change in temperature reduced the harbor water from 31° to 29°, causing the death of all adult codfish ° held in the inclosures awaiting the ripening of their eggs. The fish thus killed amounted to 204, and operations were abruptly terminated. Many of the fish in the harbor were killed, among them cunners, tautog,andeels.

The operations of this station had been jointly conducted by this Commission and that of New York, of which latter it was the property. The reduction made by Congress in the appropriations for the work necessitated a curtailment of expenses, and the association of the two commissions was discontinued with the close of July, 1892. DELAWARE RIVER STATION (LIEUT. ROBERT PLATT, U.S. N., IN CHARGE). In pursuance of the usual practice, the United States Fish Commis- sion steamer Fish Hawk was employed in the propagation of shad on the Delaware River. This steamer during the greater portion of the year was occupied with special investigations concerning the oyster, ete., but on May 12 arrived at Gloucester City, N. J., to take up shad hatching. As in former years, the egg-collecting and the manipulation necessary to development and hatching were conducted by the crew of this steamer. The period of operations, May 15 to June 2, was rather more brief than usual, and the number of eggs collected was relatively small, as was the case aiso on the Susquehanna and Potomac rivers. The aggregate obtained and the numbers from separate fisheries were: Howell’s Cove fishery, 4,540,000; Faunce’s fishery, 3,751,000; Bennett’s fishery, 2,117,000; Gloucester Point, 45,000; total, 10,453,000. To obtain these, 233 shad were stripped, the average number of eggs per fish reaching nearly 45,000. Between May 23 and June 7 the fry were liberated, 1,573,000 being transferred to the Hudson River and 5,349,000 to the Delaware. With the exception of May 23 to 26, the water was muddy. Temper- ature for May, maximum 68°, minimum 59°, mean 63.83°; for June, maximum 71°, minimum 67°, mean 68.20°, On May 26 the eggs of a scale carp, obtained from the river, were taken and placed in a universal hatching jar, the fry therefrom appear- ing in 85 hours. The commercial fishermen at that time took quantities of carp which sold readily on the shores at 8 cents per pound. In March and April, just prior to taking up shad-hatching, the Fish Hawk was engaged in the lower part of the Chesapeake Bay, capturing, with beam-trawl] and otherwise, marine specimens, animal and vegetable, for the Fish Commission aquarium, World’s Fair, Chicago. cE BATTERY ISLAND STATION, MARYLAND (W, DE C, RAVENEL, SUPERINTENDENT). REPORT OF COMMISSIONER OF FISH AND FISHERIES. The superintendent having been assigned to temporary duty in con- nection with the Columbian Exposition, the services of Mr. E. M. Rob- inson, a former employee, were engaged for conducting shad operations during April, May, and June. On April 25 spawn-takers entered the field, but the extremely cold winter preceding caused the season to be a backward one, and the water remained cool throughout the period of operations. In addition to the low temperatures, freshets filled the water with driftwood, fishermen being unable to operate much of the time. The worst visitation by muddy water occurred May 6, which was in the middle of the period when eggs are most abundant. As a result of unfavorable conditions, collections were very light between April 30 and May 10.

There were shipped by car No. 3, 1,708,000 for the waters of the Congaree River, South Carolina, the eggs being hatched en route. An additional consignment of 987,000 was made by car No. 3 to Dighton, Mass., for streams there, the fry -being hatched on the car. Low temperature of water prevented eggs _ from developing in the time usually required, many remaining unhatched for ten or twelve days, and the fry from such, being too weak for distant transportation, were liberated in waters adjacent. Those so liberated amounted to 10,874,000. The water temperatures from April 25 to June 6, compiled from ob- servations morning, noon, and night, are set forth below: Month.

On May 31 there was a capture of 2,700 pounds reported in a single haul of a seine. On June 9 the temporary employees were dispensed with, operations ceasing, and on June 26, property having been inventoried and stored, the station was turned over to R, A.

Harron, super- intendent of aquaria, but his services being required in connection with the maintenance of aquaria at Chicago, he was ordered away early in the season. rom that time the immediate supervision of the station was under W.'T. Lindsey, custodian, the superintendent being detained at the general office in Washington by temporary assignment. The cold of the winter preceding was almost unprecedented, and a poor fishing season followed. The running of ice in the Potomac seriously damaged the temporary wharf, and it was necessary to rebuild in the month of March. The river shore was not clear of ice until Feb- ruary 9. Employees were again quartered in tents, furnished by the courtesy of Gen. Albert Ordway, commanding the District of Columbia militia. The tents were ready for occupation April 9. The adoption of tent quarters became necessary on account of lack of buildings, but their use during three consecutive seasons has demonstrated that they are more desirable than one large building. Each tent aecommodates two sleeping berths, and as the spawn-takers are usually paired off, and come in from their work at all hours of the night, it is found that by having sleeping quarters subdivided those who arrive early are less” disturbed in sleep; moreover, from a sanitary standpoint it is found that tents are greatly to be preferred. As the weather is sometimes quite harsh during the shad-hatching season, even so late as in May, the tents were provided with heating stoves made of sheet iron, which, with the necessary piping and chimney pots, cost less than $2 each. By using shavings and finely split wood the tents could be warmed and made comfortable within two or three minutes’ time. On May 6 occurred the most severe freshet since 1889. Prior to this day the fishermen had a favorable outlook, the first gill fishermen: having commenced operations as early as March 27, catching at that time 12 fish at a drift, and on March 31 some capturing as many as 22 at a drift. The results, however, were poorer than in some years. The seine operated by the Fish Commission was put overboard April 14, but, like all other fisheries, it was rather unproductive of eggs. The total results for the season were only 8,870,000. The eggs from all sources between April 17 and May 22, are shown in the statement below: Bry anseoint Seine: ses reecesce. + eee eee To ee eee 939, 000 Chapman seiner ssc st san so: Poe ee ee eae eons 958, 000 TMi Th te GUN yenh sneer eee eemerin es eet are RUM gS as ef 683, 000 Stony Ponti seine 2 = sce Sern oe en oes see ee ee eee eee 512, 000 GUUS Ie Te OT Sate Lee te a ee reels eer ae ee ee et 5, 778, 000 ft RY ET Deak ar eae eae cM ete ee ae ea i we nee 8, 870, 000 Following the practice inaugurated more than ten years ago, eggs collected were transferred to Central Station, Washington, D.

In consequence of the poor success met with by commercial fisher- ei “ REPORT OF COMMISSIONER OF FISH AND FISHERIES. 93 men, operations were greatly reduced early in May, thereby bringing the season to an early close, and there being no productive work for the spawn-takers, two of the best-trained ones were transferred to Battery Island Station, that collections there might be increased if possible.

There were retained at the station, for rearing, 250,000; these were highly successful in hatching, producing an equal number of fish, which were liberated in the inland lakes of Michigan and Indiana May 3 to 13. Brook trout.—Through the courtesy of the officers of the Flint and Pere Marquette Fishing Club, arrangements were effected for obtaining adult brook trout from Kenne Creek, a stream controlled by them. The. fish were readily secured in October by two employees of the North- ville Station and Mr. George Brown, associated with the club. In four | days 415 were secured with hook and line and transferred to the station without loss. Kenne Creek was first stocked in 1880, and in the first season of fishing, 1892, more than 5,000 fish were captured, none measur- ing less than 6 inches. From original brood fish in ponds, 244,500 eggs were obtained from 285 fish between October 26 and January 12, and from the new stock of trout, practically between the same dates, 41,600 eggs were taken from 144 fish. There were retained for hatching 120,000, and transferred as exchanges, donations, or to other stations, 90,000, as represented below: Date. Consignee. Number.

The shipment consisted of 5,000, but owing to delays en route the greater part was lost. Whitefish.—There were received from the Alpena Station, and for- warded February 20, by express, to the Fish Commission establishment at Duluth, Minn., 6,000,000 eggs of this species. Pike perch.—F¥or the purpose of illustrating fish-cultural methods in the exhibit of the Fish Commission in the Government Building at the World’s Fair, Chicago, collections of eggs of this species, to the number of 16,550,000, were made on Saginaw Bay and Detroit River in April, Mr. Herschel Whitaker, commissioner of Michigan, cooperating in their obtainment. In addition, 154,000 eggs of the common sucker were secured and forwarded. During March preparations were made for the care of the young fish derived from eggs held at the station, when the rearing-troughs were thoroughly cleaned and asphalted. The first were placed in rearing- troughs March 1. The mortality in May and June was somewhat unusual, and was charged to an insufficient supply of water and limited tank and pond areas. The number remaining on hand at the end of the fiscal year, June 30, 1893, together with other fish in ponds, is given in the table which follows: Hatched in the year— 1890 or Kind. | } 1893. 1892. 1891. pre- | viously.

September field preparations were made for anticipated collections of. eggs from the commercial fishing-grounds on Lakes Huron and Michi- gan. These preparations were continued until late in October, in the meantime repairs being made to hatching-troughs, tanks, egg-trays, and spawn-taking outfit. In November a night watchman, second assistant, and others to comprise the spawn-taking force, were tempo- rarily employed. Severe storms prevented the collection of the usual number of eggs. Whitefish.—The first eggs were received November 8, consisting of 256,000, the total by November 30 amounting to 25,040,000. The losses while hatching were: November, 320,000; December, 1,180,000; January, 660,000; February, 240,000; March, none. On the 22d of February 6,000,000 eggs were transferred by express freight to Northville Station for reshipment to the Duluth establish- ment. The eggs retained, 16,640,000, commenced to hatch April 17, continuing slowly until April 20, when, the water turning cold, very few additional ones hatched until the 25d, there being about 7,000,000 out by the end of the month. The last to leave the eggs came out | May 8. The fry proved to be of excellent quality, and between April | 27 and May 23 there were liberated 16,640,000. Lake trout.—Eggs of this species were collected during November to the amount of 2,550,000, all being transferred to the Northville Station prior to November 30, in express freight consignments, as follows: 323,000 on November 11; 678,000 on November 17; 870,0000n November 22; 180,000 on November 26; total, 2,051,000. The shortage represents the loss. The majority were taken near Thompson, Lake Michigan, but 250,000 obtained from Lake Huron by means of tugs operating from Alpena were best in quality. The water temperature November 1 was 42° F., and on November 30 it had fallen to 35°. From this date until April 13 it ranged from 32.5° to 33°, On April 19 it was 41°, on the 22d 38°, advancing after that date gradually to 41° on the 27th. From this date a gradual rise was experienced until May 27, when it was 56°. By the first of June the _ equipment was stored to await operations of the next fall. DULUTH STATION, MINNESOTA (R. O. SWEENY, SR., aND S. P. WIRES, SUPERINTENDENTS). R. O. Sweeny, sr., resigned the superintendency April 15, 1893, and S. P. Wires, foreman of Alpena Station, was appointed acting super. intendent. On June 10 Mr. Wires was made superintendent. In July the high temperature and generally unfavorable condition of the gravity water supply from Lester River rendered it impracticable to hold the young lake trout brought over from the preceding year, numbering 843,000. The surface of the water on the streams and lake was covered with a yellow powder, which on the lake was seen in areas 100 yards wide, 2 miles long, and 2 inches thick, consisting of the pollen of the flowerless plants of the family Lycopodiacee. On July 12 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 107 'Josses occurred amounting to 139,000, and as a result distribution was ‘commenced, 340,000 being liberated in that month. The mortality ‘continued, and during August 100,000 additional fish were liberated, ‘completing the distribution. Lake trout.—On October 1 preparations were commenced looking to ‘the collection of lake-trout eggs at Isle Royale. This island, in the |northwestern portion of Lake Superior, is an uninhabited wilderness ‘of jagged rocks and tangled thickets, containing neither trails, paths, nor roads, and visited by one steamer only, whose service is irregular. ‘At Grand Portage a few eggs were obtained from fish caught in pound ‘nets, all others being from gill-net captures. The weather was exceed- ingly stormy, and the quality of eggs poor. The firsteggs were received ‘at the station October 4, packed in boxes. Other shipments followed ‘throughout this month and in November, the spawn-takers returning ‘November 19. Low air temperature destroyed a number of eggs in ‘shipment and the shrinkage was great. Measured on December 13, the ‘total number was found to be 1,527,000. The first hatching occurred 21st December, 10,000 having come out from the eggs by the end of ‘the month, the last hatching occurring May 16. Fry were liberated in sixteen lots, March 8 to April 10, aggregating 850,000, there being left on hand April 15, 400,000 eggs and 695,000 fry. Losses in May amounted to 5,000, and in June to 15,000. There being a mortality of 6,000 on June 19, gravity water was discontinued, the pumps supplying water from the lake. Distribution during the month amounted to 1,075,000, - ‘deposited near the shores of Michigan and Minnesota, the total libera- tion during the year being 2,365,000. Whitefish.—There were collected by station employees in the fall 750,000 eggs of whitefish, the number on hand December 13 being esti- mated at 500,000. This number being insufficient for stocking waters of that region, eggs were assigned from Alpena and Put-in Bay stations, 6,000,000 being received from the former, with a transportation loss of 18,000, February 24, and 5,000,000 from the latter station, with a loss of 300,000, March 1. Between April 1 and 10 four lots of fry Liberated in the vicinity amounted to 145,000, leaving 10,382,000 eggs and 100,000 fry on hand April 15. During April 300,000 fry were liberated, and in May 10, 182,000, of which 2,982,000 were put out in the vicinity of the station, 6,000,000 near the shores of Wisconsin, 1,500,000 near the shores of Michigan, the last eggs hatching May 24. In December, 1892, young whitefish appearing in the vicinity of the station (an unusual occur- rence), Specimens were sent to Washington for identification. Rainbow trout.—The Neosho Station being overrun with rainbow- trout eggs, two consignments were made to the Duluth Station, 75,000 being received February 11 and 25,000 February 15. The losses from date of receipt to April 15 amounted to 5,000, leaving on hand 20,000 eges and 70,000 young. There were lost subsequently, 750 in April, 6,000 in May, and 250 in June, the last hatching occurring May 21. The distribution of 83,000 occurred in June, 43,000 being placed in the St. 108 REPORT OF COMMISSIONER OF FISH AND FISHERIES. Croix and White rivers, Wisconsin, and 40,000 in Sandy and Partridge rivers, Minnesota. Pike perch.In March preliminary ar eccaene were made for obtaining pike-perch eggs from Pike River, and on April 30 a personal reconnaissance of the locality was made by the superintendent. The collecting period was brief, extending from May 1 to 15, and owing to the slow disappearance of ice fally half of the fish had spawned before they ascended the river to the egg-collecting point where a seine could | be used. The total of eggs amounted to 14,000,000. Of this number 500,000 were deposited in the stream where obtained, the remainder being conveyed to the station. The losses following transfer were 5,860,000 in May and 2,140,000 in June, hatching occurring June 1 to 5, The distribution deberatbi 5,500,000, these being placed, before absorption | of the sac, near the shores of Michigan, Wisconsin, and Minnesota. Late in November there was a considerable fall of snow, and on December 10 ice above the dam from which gravity water is obtained | formed to a sufficient thicknessto cut off the supply to hatchery, enfore- ing the use of steam pumps in obtaining lake water from erib wells. In January the mean temperature was 5.66° below zero, and in February snow was more than 3 feet deep on a level, the ice at end of March above gravity dam being 4 feet thick. On April 30 the water tempera- ture was 35°, and on May 10 the ice was still obstructing the passage of water to the hatchery from the gravity dam. By May 31 the average .temperature of the water was found to be 39°, and in June it had reached the point of 70°. The distribution for the year was: Rainbow trout, 83,000; lake trout, 2,355,000; whitefish. 10,482,000; pike perch, 5,500,000; pike-perch eggs, 500,000. QUINCY STATION, ILLINOIS (S. P. BARTLETT, SUPERINTENDENT). The collection and distribution of native food-fishes from the over- flow river basins was continued on the same basis as in former seasons. While this work does not aggregate large numbers of fish distributed, their larger size more than compensates for absence of numbers. On July 15 the water in the Tilinois and Meredosia rivers was found to be receding, the banks at that time just beginning to appear above the surface. On July 23 the water was still high, but falling, affording an opportunity for the commencement of operations in August, when both rivers and the overflowed lands were worked. A1I collections are secured with seines, the fish being transferred by small boats and a special steamer to the railway tracks, where the cars are in attendance, The difficulties in prosecuting this class of work are great, one of the worst being the high temperatures prevailing in air and water. A large proportion of the fish captured were taken from water only 4 to 8 inches deep, with an underlying deposit of soft mud 10 inches or more in thickness, and in hauling the nets it is impossible to avoid drawing ashore quantities of this substance, thereby suffocating the fish unless quickly removed. Another difficulty is in securing at the REPORT OF COMMISSIONER OF FISH AND FISHERIES. 109 right time a sufficient number of fishes of prescribed kinds to make up a carload consignment. Were it possible to make up carloads of ,any and all kinds a large amount of time would be saved, but large jmumbers are taken that can not be utilized in making up a particular /Shipment, and the fish must be separated and some transferred to storage for filling subsequent orders. , It is found that there is a wide variation in the abundance of the. different species in different seasons. There may be one year a very | plentiful supply of a given kind, and another year the same species may be conspicuously scarce. There is a similar variation in the abundance (of species in the different localities. A particular pond may, one year, ‘produce a large number of black bass, but another season will perhaps ‘contain practically none. When large quantities of fish are secured the ‘surplus is placed in storage ponds, as the fish can not be successfully held in live cars. The common practice is to return all of the more common varieties to the waters immediately around. On Meredosia Island quite a large storage pond, not altogether safe from freshets, was provided for the holding of the surplus or reserve eatch. When operations began some fish were in these ponds from June of the fiscal year preceding. Another pond for breeding purposes, sit- uated near Naples, was secured. Itis near the Illinois River and above high-water mark, and a number of large black bass were this season introduced in it with the object of securing young bass the next season. A noticeable feature in the operations this year was the presence of great numbers of carp, quantities being taken with haul seines, they being as numerous, relatively, as any native species. In that particular locality they were consumed as food in greater proportion than any other kind. Young carp hatched in the spring of 1892 were so abundant that they were caught with hook and line at every point on the two rivers, their length being 6 to 10 inches. Operations were very much benefited by rains which fell about September 10, cooling air and water. The periods during which the cars were engaged in the movement of fishes are as follows: Car No. 1, September 24 to December 2; Car No, 2, August 11 to October 30, and Car No. 3, August 7 to November 5. The facilities for the transportation of the cars afforded by the railroad companies were the best yet secured, the officials being not only cour- teous, but furnishing a greatly increased amount of free transportation. The assistance furnished was of such importance that to this source is to be attributed in large part the accomplishment of the best season of work at this place. The number of fish sent out was not larger than in any previous year, but they were larger in size, many black bass weighing 2 to 3 pounds, but those averaging about a pound being the more numerous. When liberated the fish were counted, and with very few exceptions they were counted when loaded on ears. A large area of territory was covered in the distribution, comprising Arizona, Colorado, Idaho, Illinois, Indiana, lowa, Kansas, Kentucky, Michigan, Missouri, New Mexico, Ohio, Oregon, South Dakota, Ten- 110 REPORT OF COMMISSIONER OF FISH AND FISHERIES. nessee, Virginia, Washington, and Wisconsin, some fish also being trans- ferred for distribution in the New England States and to the District of Columbia.

The production of this station, consisting almost exclusively of quinnat salmon eggs, is largely transferred to the commissioners of the State of California. At their hatchery at Sisson the eggs are hatched and fry liberated under direction of those authorities. Mr. G. B. Williams resigned the superintendency and turned over the property of the station July 29. He was succeeded by Mr. Liv- ingston Stone, who had charge of these operations at their installation, he reporting August 10. The first salmon yielding eggs was caught August 135, the fish, how- ever, at that time being too scarce to warrant regular hauling of seine. On August 24, regular work being started, 44,000 eggs were taken. The California State law, permitting proprietors of canneries to operate seines until September 1, enabled those operators to catch nearly all the summer run of fish in the lower part of the Sacramento River, and the take of eggs from the summer run amounted to but 834,000. Egg operations lasted only nineteen days, during which time 220 spawning fish were handled. All eggs taken, with the exception of about 500,000, were forwarded to the State hatchery at Sisson. Egg collections from the fall run of fish commenced October 20, the number obtained being 2,273,000. At this time funds having been exhausted, operations would have ceased but that the California com- missioners came to the rescue and paid expenses during a period of about one week, there being obtained through their efforts 423,000 additional eggs." The whole number of salmon spawned during the fall run amounted to 620, the eggs produced being 2,696,000, and the aggregate for the year being 3,530,000. Work was abruptly stopped November 26 by a violent snow-storm. The eggs taken from the last run were forwarded to Sisson. ~118 REPORT OF COMMISSIONER OF FISH AND FISHERIES. Storms were frequent and of severe character. In October 250,000 egos were destroyed by high water, and in December the McCloud River was swollen to a height of 174 feet, no mails being received during a period of ten days. The current wheel, supplying the hatchery with water, escaped damage, and at the end of the season was taken to pieces and stored. In the statement which follows it will be seen that 533,100 young salmon were liberated at the station, these having been placed in the McCloud River in December.
