By W. H. SHEBLEY, in charge Department of Fishculture. The California Fish Commission was created by an act of the legislature, entitled ‘‘ An act to provide for the restoration and preser- vation of fish in the waters of the state,’’ approved April 2, 1870, The United States Commission of Fish and Fisheries was established by joint resolutions of Congress, approved February 9, 1871. Califor- nia, therefore, had an organized fish commission nearly a year before the "federal government took up the work of multiplying the food fishes and thereby increasing the food resources of the United States. The object of the first endeavors of the California Fish Commission was the introduction and acclimatization of new species of food and game fishes. As eggs could be obtained more easily than adult fish, suitable hatcheries for the hatching of eggs became a necessity. 17703 62 CALIFORNIA FISH AND GAME. ACCLIMATIZATION SOCIETY HATCHERY. The California Acclimatization Society, under the supervision of Mr. J. G. Woodbury, first began experimenting, and had made several sue- cessful hatches of eggs introduced from the Eastern states previous to the establishment of a state fish commission. A small hatchery, situated near the City Hall in San Francisco, was utilized in this pioneer work. STATE HATCHING HOUSE AT BERKELEY. The first hatchery owned and operated by the state was situated on the grounds of the State University at Berkeley. Up to 1873 the Accli- matization Society actually operated this hatchery and was paid by the Fish Commission for the trout reared. CLEAR LAKE EXPERIMENTAL HATCHERY. In the early seventies, also, a temporary station was operated on Kelsey Creek, tributary to Clear Lake, for the purpose of hatching a shipment of whitefish sent to the California commission by the United Fic. 32. United States Fish Hatchery at Baird, Shasta County, in July, 1882. me was for many years the mcst impertant salmcn-egg collecting station in California. States Fish Commission. Hastern brook trout, landlocked salmon and whitefish, as well as the native varieties, were propagated with some success, but the location was not suitable for carrying on the work on a large seale. BAIRD HATCHERY. The circumstances surrounding the establishment of the first salmon hatchery are as follows: In 1872 the United States commission instructed Dr. Livingston Stone to proceed to the Pacifie Coast and there obtain a supply of salmon eggs from the Pacific salmon. Dr. Stone was at that time one of the recognized authorities on fisheulture in the United States. He had been engaged in the work of fisheulture CALIFORNIA FISH AND GAME. 63 for a number of years in New Hampshire and other Eastern states, was a man of education and a close observer of all things in nature. Dr. Stone arrived in San Francisco in August, 1872. He could gain no reliable information regarding the habits of the Chinook salmon or where they spawned. A general impression prevailed that the spawning erounds were near the confluence of the Sacramento and San Joaquin rivers, but after an investigation of this region Dr. Stone concluded that the fish spawned elsewhere. Mr. Montague, chief engineer of the Southern Pacific Company, informed Dr. Stone that he had seen salmon spawning at the junction of the McCloud and the Pit rivers. At that time the terminus of the railroad was at Red Bluff, fifty miles from the spawning grounds on the McCloud River. Dr. Stone was accompanied on his trip to this section by Mr. John G. Woodbury, who had been in the employ of both the California Acclimatization Society and the California Fish Commission. After many hardships and struggles to obtain material and supplies, they succeeded in establishing on the McCloud River the first salmon- breeding station on the Pacific Coast, naming it Baird, in honor of Spencer F. Baird, Commissioner of Fisheries. The summer run of salmon was nearly over and, judging from Dr. Stone’s report, the salmon run in the Sacramento River was very much depleted. From the advent of the whites up to this time, there had been a great demand on the salmon of the Sacramento River; and with no hatcheries to increase their numbers, no adequate laws to protect the breeding fish (and with the great spawning grounds of the Feather, Yuba, Bear and American rivers destroyed by the mining operations on their head- waters), in a few years little was left of the great run of fish that had previously entered these waters. The salmon had abandoned them altogether, as the eggs deposited on the spawning grounds in these streams did not hateh, being destroyed by the detritus from the mines. The only natural spawning grounds left to the salmon were in the tributary rivers that formed the headwaters of the Sacramento River, the principal streams being Mill Creek, Battle Creek, Pit River and its tributaries, Hat Creek and the MeCloud River, and the main Sacra- mento River, above the mouth of the Pit. These proved to be good salmon streams, but the great drain on the salmon and the destruction of nearly one-half of the spawning beds, soon greatly diminished their numbers. The first season’s operations on the McCloud River, by Dr. Living- ston Stone and his assistants, were experimental to a great extent. Only 50,000 eggs were taken, and of this number but 30,000 were fit to ship when they had developed to the proper stage. The eggs were shipped to a hatchery in New Jersey and 7000 hatched; and on the advice of several state commissioners and fishculturists the fry were planted in the Susquehanna River. The following season the Baird Hatchery was enlarged and the work of collecting and hatching salmon eggs was begun in earnest. From 2,000,000 to 14,000,000 eggs were taken annually at this station from 1872 to 1883. In 1881 the plant was destroyed by a freshet, but was immediately rebuilt. The California Fish Commission assisted in the work at Baird by paying a portion of the operating expenses, and in return received eggs for hatching and fry for planting. The main object of this 64 CALIFORNIA FISH AND GAME. hatchery for the first few years was to secure eggs to ship to the Kast for the purpose of introducing Pacific salmon in the waters of that section. The commission early made an agreement with the State of California, however, under which the latter at first paid part of the expense, while the commission hatched and planted a portion of the take in the McCloud River. Later, part of the eggs were turned over to the state, which hatched and planted the salmon in local waters. About 25 per cent of the total number of eggs taken during this time were hatched at this station, and the fry each season were liberated in the McCloud River, under the supervision of Dr. Stone, superintendent of the hatchery. The cost of hatching and planting was borne by the California Fish Commission. The remaining eggs were shipped to the Eastern states and to foreign countries. Shipments of the Chinook salmon were made to the principal countries of Europe and also to Japan and New Zealand. In 1883 the United States commission quit operations on the McCloud River. Only 1,000,000 eggs had been taken during the sea- son, this being the smallest take in the history of the work on this stream since the preliminary work of 1872. This great falling off in numbers was due largely to the heavy blasting and other operations on the line of the railroad which was then being constructed from Redding northward. The salmon undoubtedly were frightened so that they did not ascend the Sacramento River; besides, a great many were taken by the grading gangs and used in the camps for food. Thousands of trout and salmon were destroyed by powder used by the Chinese and white laborers, of whom there were 9000 camped along the Sacramento River; and while a great many of the fish were used as food, there was wanton destruction in the way they were killed. The same condition existed in 1884, and Superintendent Stone recommended that the sta- tion be not operated that season. It remained closed from that date until 1888, the year that the Sisson hatchery was established by the state. SAN LEANDRO HATCHERY. Finding the state hatchery house at Berkeley too small for the quantities of fish required to be hatched, as well as lacking in a relia- ble water supply, a larger hatching house was built on Lake Chabot, on the property of the San Leandro Water Works, near San Leandro, Cali- fornia, in 1878. Here much of the trout work was carried on until the Shebley Hatchery in Nevada County was taken over by the state. SHEBLEY HATCHERY. In 1883 the California Fish Commission abandoned the San Leandro Hatchery, located near Lake Chabot in Alameda County, owing to the fact that the water was too warm for successful hatching and rearing to be accomplished during the warmer months of the year; also, the water was not suitable for the propagation of healthy fry. A site was selected in Nevada County on the ranch of Mr. J. V. Shebley, who donated to the state the use of the site and the water for hatchery purposes. The first superintendent was Mr. J. A. Richard- son, a fishculturist formerly employed by the United States commission CALIFORNIA FISH AND GAME. 65 at Baird, and by the California Fish Commission, as an assistant to Mr. J. G. Woodbury at the San Leandro Hatchery. The work accomplished at the Shebley Hatchery was limited, owing to the small amount of money appropriated and the great cost of trans- porting the fry to the waters to be stocked. The commission had to pay expressage on all shipments of eggs and fry distributed. The principal work was the hatching of rainbow trout, the black-spotted trout of the Tahoe basin, and also a number of shipments of eastern brook trout and landlocked salmon. This hatchery was operated until 1888, when the board decided to establish larger hatcheries located near the egg-collecting stations, where an unlimited supply of water could be had. Accordingly, in 1888, after the distribution of fry was over for the season, the Shebley Hatchery was abandoned, and in the follow- ing spring the tools and apparatus that were the property of the state were shipped to the new hatchery on Lake Tahoe, at Tahoe City. FRAZIER HATCHERY. Frazier Hatchery was established in 1875 by I. C. Frazier, on Squaw Creek, Nevada County, under permit and authority granted by the State Fish and Game Commission. This hatchery was operated until 1880, when it was abandoned. HURLEY HATCHERY. The Hurley Hatchery was established in May, 1880, by John Hurley under permit from the Fish Commission. During that year there were hatched and distributed over 95,000 trout. Captain Todman, with the authority of the commission, leased the hatchery and hatched and released over 500,000 trout during the year 1887. The commission in 1888 took over the hatchery, and before the end of June had hatched and distributed over 600,000 trout. HAT CREEK HATCHERY. In 1885 the California Fish Commission decided to establish a hatchery for the propagation of salmon, as the federal government had not again resumed operations at Baird, on the McCloud River. After examining a number of sites, it was decided to establish a hatchery on Hat Creek, with the exception of Fall River the largest tributary of the Pit. Hat Creek is a large stream, carrying about 26,000 miner’s inches of water, and is not subject to sudden floods. The commission had the plans of the hatchery made after the design of the old Baird Hatchery and let the work out by contract. The hatchery was a large building for those days; it was constructed of good material, was 100 feet long, 46 feet wide, and contained 64 hatching troughs when com- pleted. It had a capacity of 90 troughs, but all were not put in, as the run of salmon did not justify the expense. There was a complete filtering plant and the hatchery was fully equipped to care for from 6,000,000 to 10,000,000 eggs. The year following its completion, Mr. J. V. Shebley took charge of the station. He began operations early in August, but although trapping and seining for the spawning salmon 66 CALIFORNIA FISH AND GAME. Fic. 33. W. H. Shebley and H. E. Southern examining Klamath River trout on Cottonwood Creek, near \Hornbrook, Siskiyou County, about 1904, CALIFORNIA FISH AND GAME. 67 was continued until November, only 1,200,000 eggs were collected. The spawning beds that a few years before had been covered with thousands of spawning fish were now deserted. In 1887 W. H. Shebley was appointed superintendent of the Hat Creek station, to succeed J. V. Shebley, who resigned from the commission to engage in private busi- ness. The take of eggs the second year was less than that of the first. Every effort was made to procure sufficient eggs to justify the commis- sion’s operating the plant, but only 500,000 were taken. In the spring of 1888 Superintendent W. H. Shebley recommended to the Board of Fish Commissioners and to Governor Waterman that the Hat Creek Hatchery be either abandoned or closed down for a num- ber of years, and that a station be established lower down the river at a place where the salmon eggs could be collected and shipped to a hatch- ery along the line of the railroad. It was demonstrated beyond any doubt, during the two seasons that Hat Creek station was operated, that the spawning salmon did not reach Hat Creek, nor the Pit River near its confluence with Hat Creek, in numbers sufficient to justify the expense of operating the station any longer. In former years a large run of salmon ascended Pit River as far as the falls below the town of Fall River Mills, and also into Hat Creek; but owing to the dimin- ishing number of salmon in the Sacramento River and its tributaries, the fish that ascended the river found ample spawning beds lower down, near the confluence of the Pit, the Sacramento and the McCloud rivers. The board, acting on this recommendation, ordered the hatchery closed and began looking for another site. MOUNT SHASTA HATCHERY. In August, 1888, Mr. J. G. Woodbury was appointed superintendent of hatcheries of the California Fish Commission. He immediately began to look for a suitable location for a large hatchery along the line of the railroad, at the headwaters of the Sacramento River. After making a thorough examination and a study of the conditions of the different streams, it was decided to locate the hatchery on Spring Creek, near the town of Sisson, on the property of Mr. J. H. Sisson. Spring Creek has its source in a large spring about a mile from the hatchery ; the water is pure and cold and its temperature does not vary to great extremes. The good judgment shown by Mr. Woodbury and Dr. Stone in selecting this location has been proved by the successful work done at Sisson during the ensuing years. The first hatchery on this site was built in the fall of 1888. It was a plain wooden structure 40 by 60 feet, containing 44 troughs, and was hurriedly constructed to accommodate the eggs that were being collected by the United States commission at Baird from the fall run of salmon in the McCloud River; for the federal commission had resumed operations on the MeCloud River, after having closed the station for five years. An agreement had been entered into whereby the United States commission and the California commission were to divide the work of propagating salmon in California; the former was to collect and prepare the eggs for shipment, the latter to hatch and distribute them. 68 CALIFORNIA FISH AND GAME. The Sisson Hatchery was completed and ready for operations in September, 1888. The floods did not interfere with the work, and Dr. Stone operated until late in November. Eight hundred thousand eggs were collected from the early fall run and 2,200,000 from the October and November, or late fall run. These eggs were hatched and the fry fed until they were large enough to care for themselves and then care- fully distributed in the upper reaches of the Sacramento River and its tributaries. The policy of feeding the fry was continued until 1895, when it was discontinued by the Board of Fish Commissioners as a matter of econ- omy coupled with a wrong idea that had been advanced by those who were dictating the policy of the fishcultural operations in California Fig. 34. The old Sisson Hatchery in 1894. that the salmon fry were better off if distributed as soon as the umbil- ical sac was absorbed. The benefit of feeding the fry was plainly dem- onstrated by the great increase of the salmon in the Sacramento River in the years that followed the return of the output of fry from 1888 to 1896. The fry at the Mount Shasta Hatchery are first held and fed in the troughs about two months before they are removed to the ponds. Then they are taken out in small lots and fed until all are accustomed to the new surroundings. The pondkeeper distributes the food slowly at the different feeding stations in the ponds, until he is satisfied that all the fry have received their share of food. By this method the fry all make the same development and growth, and there is no danger of developing a lot of precocious fry to exercise their cannibalistic instinets on the others. In 1911 it was decided to again hold and feed the salmon fry until they were large enough to care for themselves when distributed, as well as to hold a large number of them in the ponds at the Mount Shasta AND GAME.

Hatchery until fall and then release them in the upper reaches of the Sacramento River during the early fall, before the winter floods. Dur- ing the season of 1913 three quarters of a million salmon fry were held in “the ponds at this hatchery and released during October. During the season of 1914, 21,000,000 salmon fry were held in the troughs, nurser- ies and ponds and fed until late in the spring. Of this number, 4,000,000 were placed in the large ponds at the Mount Shasta Hatchery in perfect condition, where they were fed daily and looked after by skilled fisheulturists until the early fall, when they were released, so that their descent of the river might be less hazardous and a greater pumber might reach the ocean than is the case with the fry released in the spring or summer. This policy of holding and feeding all of the salmon fry before releasing them, and then only when the flood season is over in the spring, has unquestionably given good results. It is believed that it was the holding and feeding of the fry in the early history of the Mount Shasta Hatchery that increased the run of salmon in the Sacramento River, and that the present run is largely due to these efforts. During the year 1913 three new ponds were constructed for the rearing of brood fish, making in all a total of fifty-one ponds and nur- series. With the increasing demand for fish to stock streams, it was found necessary to increase the pond system sufficiently to raise enough stock fish to supply the eggs. Located as it is at an altitude of 3500 feet above sea level, on the southern slope of Mount Shasta and in the heart of Strawberry Valley, with a wonderful supply of pure cold water, within a mile of the main line of the Southern Pacific Railroad and but a couple of hours by rail from the rainbow trout egg-collecting stations on the Klamath River, Mount Shasta Hatchery is ideally situated. It not only has a capacity for handling the bulk of trout fry, but is also capable of rearing a sufficient number of salmon fry to maintain the salmon run in the Sacramento River. The development of this hatchery from a small salmon hatchery to its present size has been gradual. Each year permanent improvements have been made. From the first small permanent building, 40 by 60 feet, containing 44 troughs, erected in 1888, the plant has been enlarged until at the present time it includes seventeen acres of land owned by the state, with a water right of 700 miner’s inches; fifty-one ponds and nurseries for the rearing of thousands of fish; five hatchery buildings containing 450 troughs; a superintendent’s residence; three cottages for the foreman and assistants; a spawning house; a barn, sheds, garage and other buildings, and an electric lighting plant. The value of the lands and improvements, together with the apparatus and equipment necessary to maintain a station of this size, estimated at the cost of the purchase price and of construction, is £100,000. In addition to this equipment, the commission has leased outside the grounds but within a radius of a quarter of a mile of the plant, three large ponds which are used for rearing salmon fry. The capacity of these ponds is 3,000,000 fry. A one and a half-ton truck is used for hauling mate- rials and supplies from the town of Sisson, which is one mile distant, and for hauling fish and eggs to and from the trains. As many as CALIFORNIA FISH AND GAME. al 100,000 fish are retained in the fifty rearing ponds as breeders. Ten to thirty million trout and salmon are hatched and reared at the station each year. MILL CREEK AND BATTLE CREEK HATCHERIES. The work of collecting salmon eggs has been systematically carried on by the joint operations of the federal and state commissions, with the object of increasing the number of salmon in the Sacramento River. Two hatcheries have been established for the work, one at Battle Creek, in 1895, by the state commission; the other at Mill Creek, in 1902, by the federal commission. Fic. 36. The first salmon-egg collecting station on Battle Creek in 1905. In the first year of operation the take amounted to ten million salmon eggs. The Battle Creek Hatchery has proved to be one of the greatest salmon-spawning stations in the world, as many as 60,000,000 eggs hav- ing been taken in one year. It was largely due to the efforts of Mr. John P. Babcock that this fine station was located. He had taken a keen interest in the propagation of salmon and recommended this site to the California Fish Commission. Battle Creek is one of the large tributaries of the upper Sacramento River; it rises in the watershed of Mount Lassen and flows into the Sacramento River about twenty miles north of Red Bluff. There is a lagoon two and a half miles long at its mouth, in which the fall-run salmon gather in thousands. The Cali- fornia Fish Commission operated this station for two years, but owing to a lack of funds, and desiring to see the station operated to its fullest capacity, a proposition was made by the state commission to Hon. J. J. Brice, then United States Commissioner of Fisheries, to purchase the plant for a government station, the money thus obtained to be applied 12 CALIFORNIA FISH AND GAME, to increasing the capacity of the Sisson Hatchery. Commissioner Brice accepted the proposition and laid the matter before Congress, and the necessary appropriation for purchasing the station was made. The eges collected at this station, as well as at the other federal stations in the state, have been largely turned over to the California commission for hatching and distributing. During the two years that the Battle Creek station was operated by the California commission, Messrs. E. W. Hunt, superintendent of the Tahoe Hatchery, and W. H. Shebley, superintendent of the Sisson Hatchery, cooperated in the immediate supervision of the work. The salmon have gradually increased as the result of artificial propa- gation and the protection of the spawning salmon on their way to the breeding grounds at the headwaters of the Sacramento River and its tributaries. As an illustration of the wonderful results obtained, the United States commission collected and shipped to Sisson from the summer run of 1888 but 800,000 eggs, and 2,000,000 from the late fall run. With this small beginning, the great work of restocking the Sac- ramento River gradually increased until, during the season of 1905-— 1906, the federal Bureau of Fisheries collected 100,000,000 salmon eggs at the three stations—Baird, Mill Creek and Battle Creek. During the season of 1903-1904, there were hatched at the Sisson Hatchery 58,000,- 000, and in the season 1905-1906, 96,000,000 salmon eggs. This great work was made possible by the construction of batteries of troughs out- side of the buildings, in which to hatch the surplus eggs, the nurseries being used to rear the fry, as they could not be held in the troughs until large enough to be liberated. MILL CREEK EGG-COLLECTING STATION. This station is the property of the federal bureau, but was operated in 1912 by the California commission. Theretofore the salmon eggs had been hatched largely at Sisson, and as the prospects were unusually promising for the previous season it was feared the capacity of the Sisson Hatchery would be overtaxed. Accordingly, arrangements were made with the federal bureau whereby the state operated the Mill Creek station. During the year 1902 a substation was established on Mill Creek, a stream which has its source in the foothills of the Sierra Nevada Moun- tains, in the northeastern part of Tehama County, and empties into the Sacramento River from the east about a mile above the town of Tehama. The eggs were retained here until eyed, and then were shipped to other hatcheries. REDWOOD CREEK AND KORBEL HATCHERIES. Continuing to increase their salmon operations, the United States Fish Commission in 1889 erected a salmon hatchery at Fort Gaston, in the Hoopa Indian Reservation in Humboldt County. An additional egg-collecting station was established on Redwood Creek in 1893, and the same year a new hatchery was built near Korbel, on Mad River, but on account of inaccessibility, all three stations were abandoned in 1898. CALIFORNIA FISH AND GAME. 73 LAKE TAHOE HATCHERY. In the spring of 1889 Superintendent Woodbury, acting under instructions from the Board of Fish Commissioners, decided to locate a permanent hatchery on Lake Tahoe. The state had been carrying on hatchery operations under the direction of Mr. I. C. Frazier, in a rented building that was not properly equipped to do good work. Each season a few hundred thousand eggs had been taken from the black-spotted trout of Lake Tahoe and shipped to the Shebley Hatchery in Nevada County, and when the fry were hatched they were shipped back to the Truckee and Tahoe region and distributed. After a study of conditions the hatchery was located near Tahoe City, at the north end of the lake. The water supply was furnished from springs rising on the land used as a hatchery site. Thirteen acres were first rented, but later purchased so as to secure all the available water to be had near the site. At this hatchery millions of black-spotted trout were annually reared until 1916. During the season 1891 the Tahoe Hatchery, as well as the other hatcheries, was not operated, owing to dissension among members of the board. Three private hatcheries, located at Del Monte, Glen Ellen and Alma, were supervised by the state for a few years, but the result- ing hatch was negligible. In 1892 the Sisson Hatchery was reopened but the Tahoe Hatchery was not reopened until 1894, when Mr. E. W. Hunt was appointed superintendent. The work of propagating the black-spotted trout of Lake Tahoe was systematically taken up by Mr. Hunt, and the increased number of fish in the Tahoe region is evidence of his energetic and intelligent work. The increase of trout in Lake Tahoe, like the increase of salmon in the Sacramento River, is well demonstrated by the work of the egg-collecting stations. In 1890 the commission seined on all the available places in the lake where it was thought spawning fish could be taken, besides operating traps in three of the best creeks flowing into the lake, and only 873,000 eggs were procured. In 1910, 6,000,000 were taken at the Taylor Creek egg- collecting station alone. THE NEW LAKE TAHOE HATCHERY. By 1916 it had become more and more evident that the supply of water at the old site of the Tahoe Hatchery was entirely inadequate. Consequently, during the fall of 1917, a survey was made of all the available and suitable streams flowing into Lake Tahoe, and after a careful examination a site was selected at Walker Springs, one mile north of the present site, on the state highway. The Walker Springs run, during the minimum flow, 30 inches of water, and during the maximum flow a couple of hundred inches; and this during the season of greatest hatchery activity. Therefore the state secured a most desir- able site to carry on hatchery work, and the only suitable water for hatchery purposes in the Tahoe Basin proper. The streams that have their sources in the mountain range surrounding Lake Tahoe carry too much detritus and are too roily during the time the snow is melting. After purchasing the property, plans were made by the state architect for a modern stone hatchery with four times the capacity of the old 74 CALIFORNIA FISH AND GAME, Fic. 37.

The contract was given to Mr. Matt Green during the sum- mer of 1919. Work was begun on the new hatchery that fall and was completed in the fall of 1920. The new hatchery contains 64 troughs and has a capacity of about two and a half million trout. Provision has also been made for breed- ing ponds and nursery ponds and a superintendent’s cottage. This new hatchery was made the more necessary because of the lack of water at the Tallac Hatchery during the past few years. The new Tahoe Hatch- ery is of sufficient size to handle practically all of the black-spotted trout operations. At the request of Governor Stephens and the citizens of Placer County, the old hatchery grounds were converted into a public camp- ing ground by an act of the legislature during 1918, and the manage- ment of this public park was placed with the Fish and Game Commis- sion, which has improved and maintained it from the funds collected from hunting and angling licenses. MOUNT TALLAC HATCHERY. In 1895 Lawrence and Comstock erected a temporary hatchery near Tallac, about two miles from the mouth of Taylor Creek, and placed it under the control of the commission. The following year operations were moved to Tallac Creek. For a number of years a good proportion of the eggs taken in the vicinity were hatched at this station and dis- tributed in the public waters of that region. However, owing to the distance from the spawning grounds and the small supply of water, it was decided in the fall of 1908 to abandon this hatchery and erect a substantial modern building on Taylor Creek near Tallac, where a large supply could be obtained and where the work of hauling the eggs to the hatchery in the early spring, when the country is covered deep with snow, would not be so difficult. After securing a lease for a term of years from Mrs. Anita M. Baldwin, the new building, 40 by 70 feet, was erected. It has a capacity of 3,000,000 eggs and is splendidly equipped. Since a dam was erected on the stream above the hatchery, however, water conditions have not been so good. GLEN ALPINE HATCHERY. Through the joint efforts of Mrs. George Pierce of Glen Alpine Springs, and Professor W. W. Price of Alta, a small hatchery was com- pleted at Glen Alpine in 1905 and was operated as an auxiliary to the other two Tahoe stations until 1912. It was only a small building, the property of the Glen Alpine Hotel Company, having a capacity of 1,000,000 eggs, and was used by the commission to hatch out a few hundred thousand eggs to save the cost of transportation of the fry. BEAR VALLEY HATCHERY. To satisfy the feeling of necessity for a hatchery in the vicinity of San -Francisco, and after careful examination of the waters of the neighboring counties, Bear Valley, in Marin County, was finally selected as the site for this hatchery, which was erected in the fall of 1891. It was operated as a trout station during the seasons of 1892 and 1893, but was closed for trout work in 1894. Owing to the limited supply of 76 CALIFORNIA FISH AND GAME. water and the great distance from the railroad, it was considered neither economical nor expedient to operate this station longer. The efforts of the board were to concentrate the principal trout work at Sisson, aside from the work done at the Tahoe Hatchery for the propagation of the black-spotted trout of that region. WAWONA HATCHERY. In 1895, under the supervision of W. H. Shebley, a small hatchery was erected at Wawona, to provide fish for the lakes and streams in the Yosemite Park and adjacent country. The hatchery was erected and equipped by the Yosemite-Raymond Stage Line and turned over to the commission to be operated upon condition that an annual hatch of 500,000 trout eggs should be distributed in that vicinity. It was man- aged for a number of years by Mr. M. L. Cross, who was remarkably successful in the work, principally that of hatching rainbow trout eggs and eggs of the black-spotted trout of the Tahoe Basin. The eggs were shipped to this station, and the fry distributed throughout the lakes and streams of Yosemite National Park and the surrounding country. The German brown trout also has been distributed in a number of the lakes and streams, and has done remarkably well. By 1916 the hatchery and equipment had become go old that operations were suspended. In 1918, however, a new hatchery was con- structed on the old site and the old equipment temporarily installed. Later the newer equipment from the Yosemite experimental hatchery was substituted. PRICE CREEK HATCHERY. In its endeavor to increase the salmon supply in California the commission investigated conditions on Kel River, and in 1897 a hatch- ery was erected on Price Creek, one of the tributaries of Kel River, about twelve miles from its mouth. The first eggs were shipped from Battle Creek to the new station in December of that year. This station proved to be a great success. Eel River, like the headwaters of the Sacramento, has no predatory fish except the trout to devour the salmon fry. The water of the river from the mouth of Price Creek to the ocean flows through deep pools, with very little current. The salmon fry find perfect conditions in this stretch of water, and enter the ocean with very little loss and in fine condition. This station has also been used for collecting and hatching steelhead eges for distribution in the streams in Humboldt County. The increase of salmon in Eel River, following the establishment of this station, is another example of the benefit derived from artificial propa- gation. At the time the first salmon fry from the hatchery were lber- ated in Eel River during the spring of 1898, the average annual ship- ment of salmon from Eureka was about 500,000 pounds. After the establishment of the hatchery there was a steady increase, and in 1904 the shipment was over 1,500,000 pounds. A most remarkable example of artificial propagation of salmon is shown at this important station. This hatchery, in Humboldt County, was established in 1897, at which time the average number of pounds CALIFORNIA FISH AND GAME. Ot of salmon shipped from Eureka per year was less than 500,000. In 1899, 470,806 pounds were shipped from this territory. Five years later, 1904, the total number of pounds had increased to 1,877,000. In 1902 this hatchery made the first plant in the state of steelhead trout fry. After the spring of 1906, when the restriction prohibiting netting became effective, there was a marked increase apparent. In operating one small trap on Price Creek (which was at different times flooded) the largest number of steelhead eggs ever taken in Humboldt County was secured. In 1916 the hatchery was moved to a point on Eel River near Fort Seward. UKIAH HATCHERY. During the season of 1897 Mr. A. W. Foster, president of the San Francisco and North Pacific Railroad Company, being desirous of add- ing to the attractions of the streams along the line of his road by thor- oughly stocking them with fish, caused to be built at Ukiah a fish hatch- ery having a capacity of 2,000,000 eggs, and arranged with the commission to supply the hatchery with trout spawn, upon an agree- ment from him that the fish should be planted in public waters. Mr. Foster employed competent men to operate the hatchery, and in the spring of 1897, 700,000 trout eggs were forwarded to the Ukiah Hatch- ery. They were there successfully hatched and afterwards liberated in the public streams of Marin, Sonoma and Mendocino counties. In the spring of 1898 the commission forwarded to Ukiah 200,000 eggs. The number was reduced because the water supply of the section was affected by the dry season. The addition of this hatchery has been and will continue to be of great assistance in stocking the 1200 miles of trout water in these counties. In 1911 the Fish and Game Commission took over complete control of the Ukiah Hatchery, since which date it has continued operations. Several years ago improvements were made at the station in order to permit the eyeing of all the steelhead trout eggs taken at the Snow Mountain station. MEARS AND HAZEL CREEK STATIONS. During the early part of 1898 the commission caused traps to be placed in Mears and Hazel creeks, tributaries of the Sacramento River, near Sims, hoping to increase the output of rainbow trout. Owing to the lack of rain these creeks did not rise and the usual run of spawn fish did not attempt to ascend them, and the project was a failure. The location, however, was considered good, and the effort was renewed the next year, but as the second attempt was also a failure it was considered wise to abandon the location and try a point on the Truckee. The expense of the work at Sims was borne by the Southern Pacific Company. VERDI EGG-COLLECTING STATION. Following the failure of the attempt to take trout spawn from the Sacramento River, and still desiring to increase the output of rainbow trout fry, a point on the Truckee River known as the Essex dam, near 38—17703 78 CALIFORNIA FISH AND GAME, Verdi, Nevada, was selected, where in 1902 a cheap building was con- structed and fitted up as a hatchery to hold the eggs until such time as they could be shipped to Sisson and Tahoe. The lease for the land used was donated to the board by Mrs. Margaret Foulkes of Verdi, Nevada. The spawn fish were collected from the river by means of traps placed near the fishway on the dam, directly in front of the hatchery building. The run of rainbow trout at this point was an agreeable surprise, and was made possible by the action of all the owners of dams in the river in Nevada in placing fish-ladders on the dams and by the efforts of the peace officers of Nevada, who enforced the closed season. The Truckee River rises in California, its head being in Lake Tahoe. It passes for many miles through the mountains of California and then runs into Nevada, emptying into Pyramid Lake, so that both Nevada and Cali- fornia are intimately concerned in any action that will lead to the betterment of the fishing interests of this river. The authority for operations at this point was granted by the county commissioners of Washoe County, Nevada, who appreciated the fact that California and Nevada are jointly interested in improving the fishing conditions of the Truckee River. In addition to granting this authority, the commissioners exercised their power to have the laws enforced in Nevada. Between the last of February and the first of May 538,000 rainbow trout eggs were taken. In addition 500,000 black- spotted trout eggs were taken; for lack of hatching room, however, all but 218 black-spotted trout were liberated in the river above the traps. The total number of eggs collected at the station the first year was 1,038,000, part of which were shipped to the Sisson Hatchery and part to the Tahoe Hatchery, the balance being hatched and liberated in the Truckee River near Verdi, in Nevada. So far as trout propagation is concerned, there is no stream so naturally prolifie and so responsive to propag ation and protection as this mountain stream. The take in the spring of 1904 was most dis- couraging, although the prospects were good. There were large num- bers of good-sized fish to be seen, but the heavy and continuous storms kept the Truckee River at a flood stage for several months. The gates at the outlet of Lake Tahoe, which had been closed during the summer of 1903, had stored the water to a higher level than usual. This was quickly raised by the heavy rain and melting snow until it became necessary, in order to save the property around Lake Tahoe, to open the flood gates to their full extent. The continuous flow of such a large volume carried away dams and swept a great deal of heavy debris down the river, taking out racks and traps and making it impossible to replace them. The failure to make a good collection was due solely to the unusual conditions, the total take being about 75,000 eggs, 35,000 of which were eyed and sent to the United States Fisheries sta- tion at Leadville, Colorado. About 30,000 fry were hatched at Verdi and liberated in the waters of the State of Nevada. In 1905 the station was discontinued, the Truckee River continuing at such a height that the capture of spawning fish was not feasible with the equipment at hand. The funds of the commission would not allow a permanent barrier or trap; at least, the number of eggs collected did not justify the expense at that time. The hatchery supplies were sent CALIFORNIA FISH AND GAME. 79 to the stations on Lake Tahoe and at Sisson; the hatching troughs and other material too heavy to transport were donated to the State of Nevada, and have done some excellent service. HORNBROOK EGG-COLLECTING STATION. After a favorable report on the possibilities of taking rainbow trout spawn from Cottonwood Creek, Siskiyou County, had been made by W. H. Shebley, superintendent of Sisson Hatchery, in 1900, the board secured permission from Mr. David Horn, who owned the land on both sides of the creek, to trap the fish on his land and to make the neces- sary preparations to that end by constructing a temporary egg-collecting station. Accordingly, in January, 1901, operations were commenced by putting in a rack and large trap, also fitting up troughs in a tent for the purpose of eyeing the eggs before shipment to Sisson. It was found later, however, that the water supply taken from a spring, to be used for eyeing the eggs, was alkaline in character. Therefore opera- tions for collecting eggs were carried on, and as fast as taken they were shipped direct to Sisson to be eyed and hatched. This proved to be both suecessful and economical, as the station required then only the services of one man to watch the traps, collect the spawn fish, and place them in a ‘‘live-box.’’ Notwithstanding the fact that the trap was twice washed out by high water, 417,000 eggs were collected the first season. This was not considered a fair test of the capacity of the stream, as the storms were unusually severe and a warm rain on the deep snowfall caused freshets. Operations were continued in the spring of 1902, and a new trap was put in in February, but the first run was lost because of floods which washed out the trap and allowed the fish to pass on up the stream. In spite of these drawbacks, 686,000 eggs were taken by the last of May. The cost of collecting the eggs being so slight, it was considered that the efforts and money had been well expended and that it would be advis- able to continue to operate the station. The station was operated for several years by the California Fish and Game Commission and was then turned over to the United States Bureau of Fisheries, which con- tinued operations until 1919, when the station was again returned to this department. A eareful investigation of Cottonwood Creek with reference to the collecting of rainbow trout eggs was made during the spring and early summer of 1919, with the result that a lease for a new site was obtained from Mr. Marshall Horn and a permanent system of racks was installed therein to trap the spawning trout as they ascend the stream. A new and larger holding-tank for the fish was also installed, and with the new equipment it was possible to obtain 1,600,000 trout eggs in the spring of 1920. SALMON EGG-COLLECTING EXPERIMENTS ON EEL RIVER. The commercial fishing at the mouth of the Kel River and the spear- ing of the breeding salmon on the riffles on the upper reaches of the river necessitated the propagation of salmon in larger numbers on Eel River. Experimental work was carried on at an experimental station on Bull Creek, one of the tributaries of the South Fork of the Eel 80 CALIFORNIA FISH AND GAME. River, and also in the main river near the mouth. The results of these experiments of the last three years have not justified the expense of establishing a permanent egg-collecting station on the lower reaches of the river. There are several conditions in that region that make it seem imprac- ticable to establish an egg-collecting station there. The salmon, upon entering the mouth of the river, are compelled to remain in the large pond below Loleta until the river rises in the fall, as there is not enough water during the seasons of normal rainfall to allow the fish to pass over the wide, shallow riffles connecting the large pools from South Fork to the large pool at the mouth of the river. As a rule the river rises to a considerable extent, but not before the majority of the salmon are caught by the commercial fishermen at the mouth of the river in the large pool. It has been suggested that eggs be collected from the fish in the large pool during the early fall before they ascend the river or are taken by the commercial fishermen, but we find that the fish do not ripen in numbers great enough to justify the expense of seining them up and separating the few ripe ones from those that are green or immature. Furthermore, there is no water near the mouth of the river suitable for hatchery purposes. If eggs could be taken in sufficient quantities to justify the expense of collecting them, they would have to be taken direct to Fort Seward Hatchery on the railroad, some sixty miles up the river. The eggs collected would, in all probability, be in such small lots that it would not pay to keep the necessary help and equipment. Any attempt to place racks across the main Eel River or the South Fork, anywhere near its mouth, is almost impossible, as the loose nature of the formation is not solid enough to hold the racks and, even if this were overcome, the tremendous amount of water that comes down Eel River during flood periods, carrying logs and debris of all kinds, would make it impossible to retain any kind of a rack in the river. Further- more, if a rack could be built that would stand the flood water of the river when the salmon were running, the number of fish that would be entering the river would be all fresh run from the ocean and would have to be held too long in order to allow them to mature. An egeg-collecting station on Eel River or its tributaries must be situated far up the stream, away from the tremendous floods and the floatage matter in the river, and must be in the upper reaches near the spawning grounds, where the fish have spent the necessary time in fresh water for the breeders to mature. It takes less fry to stock Eel River and maintain the run of salmon than any other river on the coast, as there are few natural enemies of the young of the salmon to be found in the river. _There are no pred- atory fishes, no diverting canals to carry off the water where fry are lost, or overflow basins, and very few water snakes or other natural enemies. If only a few million eggs can be collected and the resulting fry planted each season, the run of salmon in Hel River ean be easily maintained provided the fishing at the mouth of the river is regulated as well as the ocean fishing, where large numbers of salmon are taken each season. CALIFORNIA FISH AND GAME. 81 EEL RIVER EGG-COLLECTING STATION. Extensive egg-collecting equipment was installed during the fall of 1921 on the South Fork of Eel River, near Branscomb. Racks, traps, holding pens and cabins for the assistants have been put in on the South Fork of Eel River. Racks and traps have also been placed in Charlie Creek, and on Kinney Creek an eyeing station has been put in and racks, traps, pens, ete., installed. The station has been equipped for extensive operations, and it is the intention to collect the eggs of the steelhead trout as well as those of the salmon. BROOKDALE HATCHERY. In 1905 Mr. F. A. Shebley located a hatchery at Brookdale for the county of Santa Cruz, on a tributary of the San Lorenzo River, twelve miles from the city of Santa Cruz. It has proved to be one of the best steelhead hatcheries on the coast, and the increased number of steelhead trout in the streams of Santa Cruz County is sufficient evidence of the success of this station. An auxiliary of the Brookdale Hatchery was established on Seott Creek, and it has been jointly operated by the California Fish Commission and Santa Cruz County. The fry hatched from the eggs collected at this station are distributed in the waters of Santa Cruz, San Mateo, Santa Clara and Monterey counties, and some of the eggs are shipped to Sisson and Hel River hatcheries for distribu- tion in other localities. Beginning with July 1, 1912, both Brookdale Hatchery and Scott Creek spawning station have been operated exclu- sively by the state and a general distribution made of the product. EDGEWOOD EGG-COLLECTING STATION. After the abandonment of the station at Verdi, the commission still considered it wise to establish a station on some stream where a supply of rainbow eggs could be collected at small cost. Superintendent W. H. Shebley of Sisson was sent to examine the different streams in Siskiyou County for that purpose. He selected a point on the Shasta River near Edgewood, Siskiyou County. The cost of operating was light and, besides, the eggs could be transported direct from the spawning station to the Sisson Hatchery, avoiding the expense of a double crew of men. The station was operated for the first time in 1906, but owing to unusual freshets which swept over the racks, most of the spawning fish were able to pass them, so that only about 50,000 eggs were taken. This, however, was considered sufficient to demonstrate the value of the station. An agreement was entered into with the Federal Bureau of Fisheries, which desired to establish a rainbow egg-collecting station, whereby the federal bureau was to bear part of the expense of operation of the station and was to receive in exchange the privilege of eyeing their eggs in the Sisson Hatchery. This arrangement was considered mutually beneficial to both commissions, and it tended to insure a continuance of the harmonious relations that existed between the two. THE SACRAMENTO EXPERIMENTAL STATION. During the fall of 1911 the commission decided to carry on a series of experiments to determine whether the eggs of the quinnat salmon could be successfully hatched and the fry reared near the city of Saera- 82 CALIFORNIA FISH AND GAME. mento. It was thought that if water could be found in which the eggs could be hatched without causing injury to the eggs and embryos, a ereater percentage of the fry would safely reach the ocean than would be the case if they were all liberated in the upper reaches of the river near the natural spawning grounds. It was maintained that under the old system of liberating the fry as soon as they were able to swim, a great many of them were devoured by predatory fishes, and others were carried into the overflow basins during years of flood. Accordingly the station at Sacramento was established. Mr. F. A. Shebley conducted the work in addition to his duties as superintendent of the Brookdale Hatchery. The experiments as carried on at Sacra- mento were of vital importance to the salmon industry. After experi- menting with the water from a number of wells, a flow of water was found on the Sherburn tract that appeared tc be pure enough for salmon propagation. The fish hatched at this station were all released in the Sacramento River. Of these, 50,000 were marked in order to determine by careful observation whether a greater percentage return as mature salmon than those that were released on the upper reaches of the Sacramento River. Nearly all of the fry that were lberated in the Sacramento River were floated in a screen cage by boat into the middle of the stream and there released. Mr. N. B. Scofield, however, took 500 in a floating box down the river, where they were held and fed for several weeks in brackish and salt water. They were not affected by the sudden change from the fresh to brackish and then to the saline waters of the straits near the outlet of the bay. In the course of the experiments and in the search for suitable water for hatching purposes, two wells were bored and the water from other wells was also analyzed and experimented with. The batteries or series of troughs used in these experiments were set up in the open air near the wells, and the pumping plants were installed temporarily. _ The best results were obtained from the well on the Sherburn tract. Here a battery of 40 troughs was set up on the levee, and the pumping plant installed in a small building of corrugated iron. These experiments were continued until the season of 1912-1913, but with no favorable results. The water did not have the life-sustaining qualities of moun- tain stream water, although a well arranged system of aeration was used, and the conclusion was reached that the well water all through the valley contains too much mineral to hatch salmon eggs without destroying or injuring them so badly that they will not thrive if they should hatch out. The undertaking was accordingly abandoned in 1913, the station was closed and the troughs and other apparatus were shipped to the Sisson Hatchery. : BEAR LAKE HATCHERY. With the aid of the San Bernardino Trout Association, San Bernar- dino County in 1914 built a trout hatchery with a capacity of 1,000,000 fish. The hatchery was located on the south side of Bear Lake. It was built under the supervision of Mr. E. W. Hunt, superintendent of the Tahoe Hatchery. The expense of the hatchery was borne by the mem- bers of the county association, and no money was solicited outside the CALIFORNIA FISH AND GAME. 83 county. The board of county supervisors had charge of the distribu- tion of the fish hatched and were able to see to it that the local streams were well stocked with the output. The object of this hatchery was to propagate rainbow trout from the fish in Bear Valley Lake. Bear Valley Lake (locally known as Big Bear Lake) is a body of water seven miles long and one and a half miles wide at its widest part. It is an artificial storage lake lying in the heart of the San Bernardino Mountains, about thirty miles from San Bernardino, at an elevation of about 7000 feet. This lake was stocked previously with rainbow fry from the state hatcheries, and these fish thrived remarkably. The association did not make a success of the hatchery and turned it over to the Fish and Game Commission. In 1919 the necessity of increasing the capacity of the Bear Lake hatchery at Green Spot Springs became apparent, the old buildings that had been erected by the Southern Califernia Trout Association being found inadequate. After procuring a permit from the forest service for a site adjacent to the site leased from San Bernardino County, a new hatchery with modern troughs was erected and fully equipped for the hatching and rearing of trout fry. The site at Green Spot Springs is about twelve miles from the egg-collecting station at North Creek. This is the only water available for hatchery purposes near Bear Lake. All the creeks dry up as the summer advanees, except some small springs used for domestie purposes. The Green Spot Springs rise near the foot of Sugar Loaf Mountain and flow through a shallow ravine toward Baldwin Lake. The water is used by the Shay Brothers on their stock ranch, after it leaves the hatchery. There is approximately 20 inches of water in the spring. It is cool and free from any organic substances, and is excellent hatchery water. During the summer and fall of 1919, general improvements at North Creek Egg-collecting Station were made, and a new hatchery at Green Spot Springs with a capacity of 1,500,000 fry was erected. The work was begun early in September, but owing to delays in getting mate- rials was not finished until late in November. At the hatchery at North Creek Egg-collecting Station, a portion of the eggs are hatched each season and the fry held until they are swimming well; then they are distributed in the most favorable places in Bear Lake, where there is an abundance of natural food. The fry can not be held in North Creek station later than the middle of July, as the water in North Creek fails by that time. The remainder of the fry reared for Bear Lake are held in the hatchery at Green Spot Springs until later in the season, when they are distributed in the lake in the shallows and other favorable spots. During 1919 plans were made to build suitable quarters for the help at North Creek Egg-collecting Station, a cabin and a new trap on Metcalf Creek, and a cabin and a trap on Grout Creek. A new trap was built in North Creek, and the egg-collecting station and hatchery were repaired and improved. The principal streams entering Bear Lake—North Creek, Metcalf Creek, Butler Creek and Grout Creek—were filled with sand from the high-water mark on the lake shore to the water’s edge, averaging in 84. CALIFORNIA FISH AND GAME. length from one-fourth to one-ha:it mile. The creeks are all short, but carry a large amount of granitic sand caused by the disintegrated granite formation through which these streams flow. These creeks had been filling up for several years, until in the spring of 1919 it was almost impossible for the breeding trout to enter them, as the water was spread over such a wide area of sand deposits that the fish could not find water of sufficient depth for them to swim in. In order to open these channels so that the fish could enter the streams and reach the traps, teams and scrapers were hired and the channels excavated through the sand deposits so that the water would have sufficient depth at the mouth of the creeks. The spawning area above the traps is so small that it does not justify allowing any of the fish to spawn natur- ally. The streams nearly all dry up before the eggs are hatched, even if they are allowed to ascend the streams and deposit their eggs. The majority of the eggs deposited by the breeders below the traps do not hatch, as they are covered over with the sand that packs so tight over the eggs that they are smothered. Consequently the stock of fish in Bear Lake must be kept up by artificial propagation almost entirely. Years ago, when the lake was first stocked, the sand deposits were not so great, as the flood waters scoured the streams out each season; but during the last five or six years the sand has accumulated to such an extent that the creeks must be kept open by removing the sand every two or three years so that the fish can reach the traps. Bear Lake has an abundance of natural feed for the trout. Besides the minnows there are a great many varieties of aquatic insects that abound in the lake in great numbers. During the last three seasons of drought these insects have increased, so that it is safe to say that there is not another body of water of equal size anywhere that has the same amount of natural food for trout. SNOW MOUNTAIN EGG-COLLECTING STATION. The Snow Mountain Egeg-collecting Station was established in 1907. Early in the season of 1915 the commission secured a lease on the Cape Horn dam from the Snow Mountain Water and Power Company for one year, with the option of an additional five years. This lease gave the commission the use of the grounds and buildings, as well as the privilege of constructing tanks, traps, ete., on the land described in the Snow Mountain Egg-collecting Station lease. The dam that makes it possible to collect the fish is located on the south fork of Eel River, about twenty-five miles from Ukiah, Mendocino County. All the steel- head trout that ascend this branch of Eel River are easily trapped in the fishway over the dam. A small battery of hatching troughs was installed and holding pens for the spawning fish were provided. As the fish ascend the fish ladder they are automatically trapped and swim directly into the holding pens, from which they can not escape. It is a very cleverly arranged scheme, and in addition to being a saving by eliminating a great deal of work, lessens the loss of fish from han- dling. Snow Mountain station is one of the best steelhead egg-collecting stations on the coast. CALIFORNIA FISH AND GAME. 85 FORT SEWARD HATCHERY. Owing to the undesirable location of the Price Creek Hatchery, it was decided to remove it to a more favorable site. Price Creek Hatchery was located on Price Creek, one-half mile from its junction with Eel River. The creek has its source in the hills near the mouth of Eel River. The country through which it flows is a loose, friable and dis- organized formation that is constantly sliding and washing away. During the winter months the creek was so full of sediment that it was only with the greatest skill and care that fish could be reared at all. In the spring the water dried up rapidly and became very warm, so that it was impossible to hold the fry later than June. The commission decided, therefore, to remove the hatchery to a more favorable location. The Department of Fishculture was instructed to select a suitable site and to move the station. After a careful survey of the streams on the line of the Northwestern Pacific Railroad, Fort Seward Creek was selected, a cold, clear stream, flowing into Eel River and about four and one-half miles above old Fort Seward, Humboldt County. The commission purchased forty acres of land near the mouth of the creek and selected a site for the hatchery about one-quarter of a mile from the Northwestern Pacific Railroad. Early in 1916 the work of moving the building and equipment to the new site on Fort Seward Creek was begun, being completed and ready for the spring hatch of eggs. A cottage for the superintendent and a cabin for the men were erected and finished in a rough way until more comfortable quarters could be arranged. The hatchery building is situated near the creek in a narrow canyon and the superintendent’s dwelling on an eminence overlooking the hatchery. As funds were limited at the time the hatchery was estab- lished, only a poorly constructed cabin could be built for the help besides the cottage for the superintendent. During the fall of 1919, two four-room cottages, of plain interior finish and shingled outside, were built, so that men with families could be employed. The water in Fort Seward Creek is the only water suitable for hatchery purposes on the line of the Northwestern Pacific Railroad. There are several streams between South Fork station and Fortuna, but they all have their sources in the same sedimentary formation as Price Creek, where it was necessary to abandon the hatchery owing to the great amount of sediment carried in the water during the winter and spring, when the rainy season was at its height. The fry produced at this hatchery are the best reared in any of the hatcheries located in the coast counties. YUBA CITY SHAD HATCHERY. Early in the season of 1916 the question of propagating shad was taken up by the Department of Fishculture. The heavy fishing for shad in the bays and in the Sacramento and San Joaquin rivers in pre- vious years had caused noticeable falling off in the numbers of these fish, and to keep the supply up it was deemed necessary to resort to artificial propagation. About the same time, a request was received from the Massachusetts and Connecticut fish and game commissions requesting the California 4—17703 86 CALIFORNIA FISH AND GAME. commission to collect shad eggs from California waters and ship them to their hatcheries, as they were desirous of restocking the depleted waters of the Eastern states with shad. Shad were introduced into California from New England states by the California Fish Com- mission in 1871. hey increased rapidly until a few years ago, and the Sacramento and San Joaquin rivers were fairly alive with them in the spring and summer, when the run of shad was at its height. The excessive fishing and pollution of the Eastern rivers has caused the shad to become very scarce, and it was the desire of the Massachu- setts and Connecticut commissions to restock their waters. It was decided to collect the shad eggs for the two commissions, as it was considered an opportune time to carry on experiments to locate the spawning places of shad, as well as to make experiments to determine whether shad culture could be carried on successfully in California and to determine whether the process of fertilizing the eggs and propagating the fry could be improved upon. Consequently the commission decided to operate a shad hatchery on a small scale during 1916, to carry out the experiments and to gather data in preparation for more extensive operations the following season. When operations were begun, in May, it was thought that all the eggs necessary for the shipments East, as well as for our experiments, could be collected by the latter part of May or early in June, but the season proved to be unfavorable and the work dragged along into July without sufficient eggs being obtained at one time to make a shipment Kast. Fishing began on June 3 at Yuba City. The run was poor all through the season in the upper reaches of the rivers; nowhere near its size in former years. The light run of shad in the upper river was due to the very cold spring, cold water, and later to the high, roily water caused by the melting snow in the higher altitudes. During the season 1,421,000 shad eggs were collected and 872,000 fry hatched and suceess- fully released in the Feather River. This work was under the imme- diate supervision of Superintendent G. H. Lambson of the Mount Shasta Hatchery. BURNEY CREEK EGG-COLLECTING STATION. In the spring of 1915 a lease was secured on a piece of land at the mouth of Burney Creek, a tributary of Pit River, Shasta County, for the purpose of collecting rainbow trout eggs. A rack was placed across the stream and the necessary live cars and pens were made to hold the fish that were expected to enter the creek. A tent and a few troughs under it with hatching equipment was set up and operations were begun. It was originally planned to eye the eggs and hatch them in the old Hat Creek Hatchery, seven miles from Burney Creek, if a suffi- cient number were taken; but early in May an eruption of Mount Lassen sent a tremendous flood of mud, water and sand down the Hat Creek Valley, destroying all the fish in the stream from its source to its confluence with the Pit River. This was one of the most serious destructions of fish life in recent years in California. Hat Creek rises in the southeastern part of Shasta County, in a lake at the foot of Mount Lassen, at an altitude of 7300 feet above sea level. It flows northerly into the Pit River, two miles northwest of Carbon, where CALIFORNIA FISH AND GAME. 87 the old Hat Creek Hatchery was located. It is thirty-eight miles in length. Its principal tributaries are Rising River, a short stream aris- ing from large springs in the lava, and Lost Creek. Rising River is only two miles in length, but has an average flow of 380 second-feet of water. Hat Creek, before its confluence with Rising River at the town of Cassell, has an average flow of about 100 second-feet during the summer months. Hat Creek and its tributary, Rising River, were noted for the excellence of their rainbow trout. After the flood of mud and Sand from Mount Lassen, the only survivors in the valley were those that were in Rising River. The water was muddy all during the season of 1915, and during the following years continued so muddy that it was not considered practical to restock the stream. It will probably be several years before fish will again thrive in Hat Creek, as the shifting sand deposited by the voleano destroys all the insect life in the stream, as well as making it uninhabitable for trout. The fish enter Burney Creek late in the summer, but the run is a protracted one, lasting from April to August. The fish are late in developing, and if the fry were reared in a higher altitude and the progeny spawned later each season, a fall-spawning rainbow trout could probably be developed. This might have some advantages over a spring-spawning fish, as such trout would be in fine condition for the anglers when the fishing season opens in the spring. MARLETT-CARSON HATCHERY. The supply of eastern brook trout fry was increased considerably in 1916 and 1917. The Nevada State Fish Commisison did not operate its hatcheries, and the California commission was able to secure the privilege of collecting eggs from Marlett Lake, Nevada. The Carson City Hatchery was taken over by the commission, and the eastern brook trout eggs collected from Marlett Lake were shipped to this hatchery, where they were eyed and prepared for shipment. At this station 690,000 eggs were collected. The second year but half the eges taken were to go to California under the agreement entered into. The share shipped to the Mount Shasta Hatchery amounted to 200,000 eggs. DOMINGO SPRINGS HATCHERY. An experimental hatchery was established at Domingo Springs in 1916. Improvements were made during 1917, when the temporary plant was moved to Rice Creek, one of the main branches of the North Fork of the Feather River above Lake Almanor. A thorough test of the water and an investigation of the run of fish resulted in the estab- lishment of a permanent egg-collecting station and hatchery at this place. Accordingly, during the summer and fall of 1919, a permanent building was erected and a substantial trap constructed, one-quarter of a mile below the falls, in Rice Creek. The site was procured from the United States Forest Service. This desirable station will furnish fry for the entire region surrounding the west side of Lake Almanor, as well as the lakes and streams in the Mount Lassen National Park and surrounding country. 88 CALIFORNIA FISH AND GAME, ALMANOR HATCHERY. Almanor Hatchery was established in 1916 at the Big Meadows dam of the Great Western Power Company on Lake Almanor. It produced 261,000 rainbow eggs in 1918 and 282,000 in 1919. The water supply fails too early in the summer to permit the hatching and rearing of fry at the station, and accordingly the eggs were transferred to Clear Creek or Domingo Springs hatcheries as soon as they were ‘‘eyed.”’ YOSEMITE EXPERIMENTAL STATION. With the intention of keeping the streams of the Yosemite Valley adequately stocked with trout fry, the commission during the fall of 1917 made a survey of conditions obtaining in the valley with reference to the establishment of a hatchery. A suitable site was obtained for a fine hatchery near Happy Isles, and application was made to the Depart- ment of the Interior for a lease to the property required for operations. Every assurance was given by the Yosemite Park officials that the department would grant a suitable lease, and pending the outcome of negotiations for the same the commission took advantage of a temporary permit granted it to establish an experimental hatchery on the site, in order that it might be definitely determined as to the practicability of the location for the propagation of trout. Arrangements were made with the State Department of Engineering for the preparation of suitable plans for the permanent hatchery. The experimental station was established during the fall and winter of 1918 and was opened up for operations in the spring of 1919. Four hundred thousand rainbow, black-spotted and steelhead trout eggs were shipped to the station, and the resulting fry were reared and planted in the streams and lakes of the Yosemite Valley with the cooperation of park officials. The fry produced were vigorous and healthy and attained an unusual size in the few months that they were reared in the hatchery. The site was demonstrated as being satisfactory for hatchery pur- poses, but as it is against the policy of the state to erect permanent buildings on leased land it was decided at a meeting of the Board of Fish and Game Commissioners, held during the latter part of October, 1920, to abandon the project. All equipment was therefore removed from the site and transported by auto trucks to the Wawona Hatchery, where it has been used to equip that station for more extensive operations. MOUNT WHITNEY HATCHERY. On February 2, 1917, the Mount Whitney Hatchery, located on a forty-acre tract on Oak Creek near the town of Independence, Inyo County, was turned over to the Fish and Game Commission by the Department of Engineering, under whose supervision the hatchery was constructed. The building is a beautiful structure of granite and gabro, and the coloring of the rubble walls blends harmoniously into the background of giant peaks that form the west wall of the valley. The building contains offices, storerooms and a laboratory on the lower floor and living quarters for the help in the upper story of the struc- ture. It is equipped with up-to-date plumbing. All the troughs have CALIFORNIA FISH AND GAME. 89 a separate water supply. The aerating system is on the latest and most modern lines. The waste pipes, catch basins and drains are all of concrete. As a matter of necessity the first season’s output was com- paratively small, but the 1,285,000 fish distributed in the waters of southern. California, the lower San Joaquin Valley, Inyo and Mono counties, were an exceptionally fine lot of fish. The ample supply of pure water in Oak Creek, that gushes from the granite rocks of the basal slopes of the Whitney Range, has proved to be excellent for the propagation of trout. The fry advance very rapidly and are strong Fic. 38. Picturesquely situated at the eastern base of the Sierra in Inyo County, the Mount Whitney Hatchery is the best constructed and best equipped hatchery in the state. and vigorous. The distribution of the fish has been very satisfactory in every particular. The grounds around the hatchery have been ornamented and improved. A large pond has been constructed, in which there are a number of adult trout of different species. Surrounding the pond are extensive lawns and beautiful flower gardens, roadways, paths, ete. While it is true that the station is located at a considerable distance from some of the southern California and San Joaquin Valley sections, which receive their supply of trout therefrom, the transportation facil- ities are very good, the trains being run on schedules which permit of the fish being delivered to the applicants within a very short time after leaving the hatchery. Consequently the fry are in the very best possi- ble condition when planted in the streams. While it may appear, to one not familiar with the existing conditions, that the distribution of the fish from Mount Whitney Hatchery is more expensive than from 90 CALIFORNIA FISH AND GAME. other stations on account of the high rate of fares from Mojave to Owenyo, the very reverse is true, for the trips of the distribution car are all comparatively short ones, enabling distribution work to be com- pleted within a short time, which materially lessens the cost of distri- bution. But the most important feature of this hatchery is the exceel- lence of the fry produced. They are truly wonderful fish, and the advantage to the southern waters resulting from the planting of such fry is inestimable. The most interestinz work undertaken at this station, from a fisheul- tural standpoint, has been the propagation of golden trout obtained from the Cottonwood Lakes station. The propagation of this species is very difficult, owing to the weakness of the embryos. The embryos hatched seem to lack vitality, and it is only by exercising the greatest care and patience in handling the eggs during incubation and in caring for the embryos, that the fry survive at all. Hewever, golden trout are being successfully reared, and some very excellent results are expected from the stocking of the streams and lakes of the southern high Sierra, in which section conditions are propitious for the successful develop- ment of this species. A supply of rainbow trout eggs is procured from the Rae Lakes, a system of lakes lying in the heart of the Sierra at an elevation of 10,500 feet above sea level. RAE LAKES EGG-COLLECTING STATION. The Rae Lakes Egeg-collecting Station was established during the late spring of 1917 to furnish rainbow eggs for the Mount Whitney Hatch- ery. At the site of operations the altitude is 10,500 feet above sea level, located on a beautiful chain of lakes set in the heart of the high southern Sierra in Fresno County. The lakes are well stocked with rain- bow trout. To reach the station in time to trap the fish as they enter the streams to spawn is extremely difficult. The trip into the lakes must be made via Oak Creek Pass, at an elevation of over 11,000 feet. There are few trails and the trip must be made through the blind mountain passes, over great depths of snow. Severe snow storms im this section, even in June, when the fish are spawning, are frequent. Even when the days are clear and warm the nights are freezing cold, and the journey through the passes is at best a difficult one, taxing the strength and resourcefulness of the hardiest mountaineers. Owing to the difficulties attending the opening up and operation of this station, and to the fact that sufficient skilled help to operate all-the state hatcheries to capacity could not be obtained, this station was not utilized during 1918 and 1919. It was again operated in 1920 and 1921. COTTONWOOD LAKES EGG-COLLECTING STATION. During the summer of 1917, preliminary surveys were made of the Cottonwood Lakes country, Inyo County, to ascertain whether it would be feasible to undertake the propagation of golden trout. The Cottonwood Lakes are situated in a rugged, almost inaccessible section of Inyo County near the Tulare County line, at the head of Cottonwood Creek. The lakes were stocked in the early seventies with golden trout from Mulkey Creek, a tributary of south fork of Kern River, and are now teeming with this most beautiful and gamey fish, CALIFORNIA FISH AND GAME, 91 It was found that a number of creeks flowing into the lakes furnish excellent spawning grounds, and on what appeared to be the most favorable locations it was decided to put in racks and trap the fish as they ascended the streams to spawn. All arrangements were made to be on the ground at the proper time. All of the lumber, tools, tents, camp equipment and supplies had to be transported by pack train over- land from Lone Pine. However, this was all successfully accomplished, and the men reached the site of the station in ample time to catch the first of the fish ascending the streams to spawn. Five hundred thou- sand eggs were taken and were successfully transported by pack ani- mals from the spawning station to Mount Whitney Hatchery. The resulting fry were distributed in waters of that section. The remoteness of the site of operations from railroads, highways or, indeed, any human habitations, the high altitude and prevalence of snow storms, make. the trip into this remote section at this season of the year actually dangerous at times. Nevertheless the work has been continued, and crews have gone into the ‘‘lakes’’ each season and sue- cessfully accomplished their mission. The results obtained have justi- fied all the hard work and expense. Although several efforts have been made in past years to collect the eggs of the golden trout, the attempt during 1918 was the first successful one. The success of the operations has been due to the skill and resourcefulness of Mr. George McCloud, who was in personal charge of the golden trout egeg-collecting opera- tions at Cottonwood Lakes and of Mount Whitney Hatchery, at which station the eggs were hatched and the fry reared. The golden trout are very difficult to rear, but the results obtained in this delicate work have exceeded expectations. The station was again operated in 1919 and 1920, but due to adverse weather conditions was not opened in 1921. FEATHER RIVER EXPERIMENTAL HATCHERY. During the spring of 1918, following out the plan of increasing the number of small hatcheries throughout the state, an experimental sta- tion was established in Plumas County, on the line of the Western Pacific Railway on a site on Grey Eagle Creek, about a mile from the town of Blairsden. Steelhead eggs were shipped to the station from Snow Mountain station, black-spotted eggs from Tallac Hatchery, and rainbow eggs from Domingo Springs station, the plan being to thor- oughly try out this site in order that a permanent hatchery might be erected thereon should the water prove to be satisfactory for hatchery purposes. From this hatchery all of the trout fry for Plumas, Lassen and Modoe counties, along the line of the Western Pacific and the Nevada, California and Oregon railways could be hatched and distrib- uted. With the inland territory in the Westwood, Lake Almanor and Juniper Lake districts covered by the Clear Creek and Domingo Springs hatcheries, and all railroad deliveries for the three counties above men- tioned taken care of by the Feather River Hatchery (as the plant near Blairsden was to be named), all long hauls to this section from the Mount Shasta Hatchery could be eliminated. Unfortunately the water of Grey Eagle Creek did not prove satisfactory for hatchery purposes, and it became necessary to locate the hatchery in this section on some other creek. In 1921 the hatchery was moved to a site on Jamison 92 CALIFORNIA FISH AND GAME. Creek, a tributary of Feather River. ‘The station is located near Johns- ville, in Plumas County. The operations last season were successful, and accordingly plans were made for the establishment of a permanent hatchery at this site. CLEAR CREEK HATCHERY. The Clear Creek Hatchery and Egg-collecting Station was established in the fall of 1918, on the creek that bears its name, one and one-half miles from the town of Westwood, Lassen County. Clear Creek is a tributary of the Hamilton branch of the Feather River, and a large portion of the spawning rainbow trout that ascend the Hamilton Branch of the Feather River enter this stream. As the source of Clear Creek is in a large spring, the water is pure and cold. The Red River Lumber Company furnished the site and material for the Clear Creek Hatchery, and the Fish and Game Commission furnished the labor for construction. Operations at this hatchery have been very satisfactory. FALL CREEK HATCHERY. In January, 1913, the California-Oregon Power Company began the construction of a concrete dam in the Klamath River two and a half miles above the mouth of Fall Creek in Siskiyou County. This dam, 110 feet high, has required a great deal of study on the part of the fisheultural department. The great problem involved was whether an efficient fishway could be constructed on such a dam, and if such a fish- way were constructed, what would be the benefit derived from such an undertaking. The principal run of fish on the Klamath River in the region of the Copeo dam is trout and salmon. The Federal Bureau of Fisheries has operated a salmon egg-collecting station on the river below the dam and have for the last eight years prevented the salmon from ascending the river above the racks at Hornbrook. This is neces- sary in order that the supply of salmon may be maintained in the Klamath River. If the racks were removed and the salmon allowed to ascend the river, and a fishway constructed that would allow the pas- sage of the breeding salmon above the dam, the resulting fry would have to return to the ocean and on their downward journey would be destroyed by the power wheels of the hydroelectric plant that takes the water from the dam. Therefore the construction of a fishway for the passage of salmon above the Copeo dam was not feasible. Accordingly, in compliance with the law, the Fall Creek Hatchery was constructed and paid for by the California-Oregon Power Company in lieu of construet- ing a fish ladder over the Copeo dam in the Klamath River. Under the provisions of the law passed by the legislature, whenever a dam or other obstruction is placed in a river or stream that, in the judgment of the Fish and Game Commission, is too high for the suc- cessful operation of a fishway, or for other reasons it is deemed best to establish a hatchery below the dam for the propagation of any species of fish that may be interfered with by the construction of the dam, the owners of the dam must construct and equip a hatchery for the pur- pose of propagating fish for the river and turn the hatchery over to the state for operation. CALIFORNIA FISH AND GAME. 93 A site was selected on Fall Creek, a tributary of the Klamath River, at a distance of fourteen miles from the town of Hornbrook and along the line of the old Klamath River Railroad. 232 =-== == Sisson, ‘Siskiyou County=.-- =) 1888 Mah oewElatene ya es=aa === tenes eee Tahoe City, Placer County_-----_-----._-- 1889-1891 1894-1920 Fort Gaston Fish Hatchery (U.

By HaArotp C. BRYANT. The fisheultural work of the state gained its initial impetus from the first commissioners, appointed in 1870, Messrs. B. B. Redding, 8. R. Throckmorton and J. O. Farwell. Because of their interest in stocking the streams with desirable food fishes, the hatching and rearing of fish received due encouragement. The first fisheulturist retained by the commission was Mr. J. G. Woodbury, who had been carrying on experi- ments in fish breeding for the California Acclimatization Society, and later for the United States Fish Commission. Mr. Woodbury devoted nearly twenty years of his life to the interests of fishculture in Cali- fornia. His principal work was done at Berkeley and San Leandro, where trout and salmon were reared, and at Clear Lake station, where the propagation of whitefish was attempted. Mr. Woodbury became first assistant to Dr. Livingston Stone at the time the government salmon-breeding station on the McCloud River was established in 1872. He was made State Superintendent of Hatcheries in 1888, and during the same year, with the assistance and advice of Dr. Livingston Stone and United States Commissioner Marshal McDonald, he located the Sisson Hatchery. The following year he located the hatchery at Tahoe City. 100 CALIFORNIA FISH AND GAME, In 1891, desiring to engage in private business, Mr. J. G. Woodbury resigned as superintendent of hatcheries. In 1893, the board appointed Mr. John P. Babeock to fill the newly created position of chief deputy of the California Fish Commission, in which capacity Mr. Babcock acted from 1893 until 1901, when he resigned to accept a position with the government of British Columbia. The successful transportation of eggs and fry from Eastern states in the seventies was due to Dr. Livingston Stone, a fishculturist of the United States Fish Commission. On each of the several difficult trans- continental trips Dr. Stone proved that he understood the care of fish. As much of acclimatization work was a cooperative project by the United States Fish Commission and the California Fish Commission, Dr. Stone was at times under the employ of the California commission. This was true also when he became superintendent of the McCloud River Hatchery, for the California commission bore a portion of the cost of hatching and planting the salmon. Mr. J. A. Richardson, who had been employed by the United States commission at the Baird Hatchery, and who was an assistant at the San Leandro Hatchery, was made Superintendent of the Shebley Hatchery when it was built in 1883. Mr. Richardson resigned in the fall of the same year, and Mr. I. C. Frazier was appointed to succeed him. Mr. Frazier was a successful and competent fishculturist, who had been a student of fish life for a great many years. In the early seventies he associated himself with some of the acclimatization societies and later established a hatchery, with rearing ponds, on the Truckee River. In 1884, owing to ill health, he resigned as superintendent of the Shebley Hatchery, and Mr. J. V. Shebley was appointed superintendent. In 1885, Mr. J. V. Shebley was appointed Superintendent of Hatcheries, and Mr. W. H. Shebley succeeded him at the Shebley Hatchery. Mr. Frazier later became superintendent of the Tahoe Hatchery, and Mr. Richardson was again employed as an assistant. When the Sisson Hatchery was built, in 1888, Mr. J. A. Richardson was appointed superintendent, and he managed the station until 1893, when Mr. W. H. Shebley succeeded him. The largest hatchery in Cali- fornia, and in some respects the largest in the United States, was for twenty-one years under the efficient supervision of Mr. W. H. Shebley. As superintendent he demonstrated that millions of trout could be successfully reared each year without serious loss. The pioneer work of introducing the first shipments of trout in the barren waters of the Yosemite region was carried on by Mr. Shebley, who introduced the first fish in the waters above the valley in 1892. In November, 1911, the commission created the office of fishculture and distribution, and Mr. Shebley was assigned to this new division of the work. = = Le =< Eon ih ’ ps PLATE III. Fic. 45.

A comparison of this with figure 43 is made easy in figure 49, where selected parts of each are placed side by side. There is here demonstrated the possibility of recognizing unmarked fish which are liberated with marked ones, providing all were treated alike, and this will warrant the close scrutiny of a great many four-year fish which enter the Klamath a year hence, especially at the Klamathon racks, where all that escape the vicissitudes of sea and river may be expected to arrive. In 1919 a single marked fish was obtained in the Klamath estuary as the only result of an experiment initiated in 1916. An account of this experiment reads as follows (CALIFORNIA FISH AND GAME, Vol. 2, No. 4, p. 209) : ‘On February 15, 1916, 3500 marked yearling quinnat salmon were liberated in the Klamath River at Klamathon. They were hatched at the Sisson Hatchery from eggs taken on Butte (meaning Battle) Creek in November, 1914. Each was marked by removing the left ventral and the adipose fin. It is expected that a few of these will be recovered in the Klamath River in 1917 as male grilse, and that both males and females will be taken in 1918, 1919 and 1920 as 4, 5 and 6-year-old fish.’’ The single fish recovered was first observed by Henry Jackson, an employee in the cannery of the Klamath River Packers Association at Requa, August 29, 1919. The specimen was presented to an agent of the Fish and Game Commission by Mr. G. R. Field. It measured 43 inches and weighed 35 pounds. Its age is plainly shown by the character of one of its scales in figure 50. Because of unfor- tunate circumstances, no very definite effort was made to recover marked fish from this experiment until it was aimost too late, and the very meagre results serve to illustrate the futility of initiating an experiment when not fully prepared to closely follow it up. The experimental planting of 1919 now gives promise of unusually good results, and no reasonable effort should be spared to secure full data relating to it. Fish bearing its mark may appear along the coast in the catches of trollers, and thus offer some evidence relating to the contribution of Klamath salmon to sea fisheries. It is known that Klamath fish are caught at sea, as salmon on entering the river bring from time to time mute evidence in the form of embedded hooks, and even entire spoons, which look like those used in sea trolling to the southward. This particular experiment is part of an effort of the Fish and Game Commission to accumulate facts relating to the habits and distribution of the king salmon which shall contribute toward the conservation and maintenance of the fishery. It is of interest to fisherman, dealer, packer and consumer alike, and no opportunity should be lost to con- tribute to its results. Any one so fortunate as to catch one of these fish should make an accurate note of it. He should measure its length from the snout to the end of the middle part of the tail (see figure 40), determine its sex, cut the mutilated fins from the body, including a liberal piece of skin, scrape a hundred or so seales from near the middle of its side, write down the date and exact locality of capture, the name and address, and mail the entire data to the Fish and Game Commis- sion. The fins should be well salted, and the scales may be spread out between two papers. 108 CALIFORNIA FISH AND GAME. THE WHY AND HOW OF MOUNTAIN LION HUNTING IN CALIFORNIA. By JAY Bruce, State Mountain Lion Hunter. The importance of the control of the mountain lion (Felis concolor) as an aid in game-conservation can be appreciated when it is realized that the present lion population of California is scientifically estimated to be about 600 lions, and their annual kill of deer 30,000 head. This is over twice the number known to be killed by human hunters. Since does are probably about five times as numerous as bucks, a lion has five chances to kill a doe for one chance to kill a buck. So, naturally, most of the deer killed by lions are the breeding stock of females. Although deer form their principal food, ons also kill thousands of dollars worth of domestic stock every year, even including full grown cattle. In fact, no animal in California is entirely exempt from the bloodthirsty instincts of these animals. I know definitely of lions hav- ing killed and eaten foxes, skunks, coons, porcupines and bobcats. I also have reliable information of several instances where lions have killed and eaten domestic dogs, while two lions now in captivity in the Yosemite Valley killed and ate a cub bear which managed to get into the lions’ cage from his own adjoining cage. The lion problem has been intensified by the establishment of a chain of game refuges where no public hunting is allowed. The breeding stock of deer and other game is fast increasing in these areas, and nat- urally the ons accumulate there. Since the lon’s instinet is to kill at every opportunity, the most damage will be dene where deer are most numerous. In order to meet this condition a high state bounty was advocated. It seemed doubtful, however, whether a $100 bounty would attract enough hunters to confer a benefit anywhere in proportion to the addi- tional cost, as will be shown later. Another method of control consid- ered was the employment of experienced lion hunters on a regular sal- ary, plus the present bounty. As an experiment along this line the writer was employed by the California Fish and Game Commission, on January 1, 1919. This system costs only about $2000 per year, as against the $15,000 by the increased bounty, and lions are killed where there is the most need of killing them. The main object of the plan adopted was to control the lions in game refuges, and then to answer any calls where lions were doing unusual damage. During the last three years I have accounted for ninety lions, as follows: 1919, twenty- six lhons; 1920, thirty lions; 1921, thirty-four lions. Most of these were taken in and around game refuges. Since October, 1908, the California Fish and Game Commission has been paying a bounty of $20° for each mountain lion killed. Claims for such bounty are made on blanks furnished by the commission, and every claimant has been requested to furnish the commission with a written statement showing where the lion was killed, why it was killed, the damage done by the NotTgE.—There have been few articles appearing in CALIFORNIA FISH AND GAME of more general interest than the one offered here, written by a man who probably knows more about the habits of the mountain lion than any other Westerner. In bagging 121 lions, Mr. Bruce has traveled on foot over 10,000 miles, hunting, trailing, and studying their habits.—Eprror, CALIFORNIA FISH AND GAME. 109 lion, methods used in taking him, and the sex of the animal. In July, 1917, the bounty on female lions was raised to $30 per head. The information sent in by claimants for bounty indicates that nearly all of these hons were killed either accidentally or because they were doing damage to stock, and not on account of the bounty. Now if the bounty were raised to $100 per lion, the state would be paying $75 more on an average for each lion now killed under the present bounty, and this would amount to about $15,000 annually. From the foregoing it might be argued that the present bounty is useless and should be abolished, so let us examine and see what benefit Fic. 51. One hundred and fifty pound male lion treed near Lynchburg ranger’s station, Placer County, November 1, 1921. is derived from this expenditure. It is evident that no situation can be handled intelligently or with efficiency without accurate data as a basis for action. Now on account of the bounty of $20 paid since 1908, the commission has been furnished with the following data: The number of lions killed during the last thirteen years; The proportionate number of these killed from year to year under a given condition, which should indicate the comparative lon popu- lation ; The damage known to have been done by each lion; The methods used in taking the animal; The percentage of each sex killed since 1917. These data are of immense value in any effort to control the lion, and are now being used to advantage for that purpose by the commission. For instance, we find from an examination of these data that the range of the lion on the western slope of the Sierra Nevada Mountains between Siskiyou County and Kern County, is confined to a straight belt about fifteen miles wide by section lines, and at an elevation between 3000 and 5000 feet above sea level and averaging 4000 feet. The same elevation will apply to the range of the lion in the Coast 110 CALIFORNIA FISH AND GAME. Range Mountains. All the country above or below this belt can be eliminated as lion country for all practical hunting purposes. The lion does not habitually follow some of the deer to the higher mountains in summer and other deer to the foothills in winter, as many people suppose. This lon belt is so well defined in the Sierra that we ean draw a straight line through the center of the belt, from a point in Siskiyou County to a point in Kern County, and it would be pos- sible for a hunter to camp along this line and kill approximately every lion on the western slope of the Sierra. Of course a lion will ocea- sionally stray out of this belt temporarily, but he soon returns, for his natural home is there. The lion probably selects this belt because it is the natural home of the deer. The variety of ceanothus, commonly Fic. 52. A large 160-pound male lion which measured 7 feet 33 inches.

Peterson. ealled deer brush, which is the principal food for deer, grows in abun- dance in this belt between 3000 and 5000 feet elevation. The deer that summer higher winter here, and those that winter below summer here. Most of the deer stay here all the year, so this area is the best all-year range for them. In other words, the maximum deer population is to be found in this area. For this reason the lioness selects some place in this belt when her young are to be born. She usually has two or three kittens, although sometimes only one, and occasionally four, are born in a litter. On account of many females not mating every year, the yearly increase probably averages one kitten for each adult female. The lair is usually located around some bluff or pile of rocks, which furnishes places for shelter and concealment of the kittens when small. In my experience, the kittens are born in either February, April, August or November. The mother nurses them for about two months, and probably brings them some food in her stomach during that time. CALIFORNIA FISH AND GAME. aia After they are weaned she makes a kill and moves the kittens to it, leaving them to eat it while she goes away hunting. She continues moving the kittens from kill to kill until they are about six months old and weigh about 35 pounds for females and 50 pounds for males, by actual seale weight. They now hunt part of the time with their mother until they are about a year old and weigh about 65 pounds for females and 80 pounds for males. The mother then abandons them. The kittens sometimes continue to hunt together for a few months longer, when they finally separate, selecting different beats, but still in the same belt where conditions are the same as where they were raised. When fully matured the male weighs from 140 to 160 pounds and measures from 64 feet to 74 feet from tip of nose to tip of tail. The female weighs from 90 to 105 pounds and measures from 6 feet to 7 feet from tip to tip. These are actual scale weights end tape measurements. The adult male accompanies the female only during the mating period and does not help to feed and care for the young. Lions do not make their kills by lying in wait on the limbs of trees and springing from there. In fact, I have never known of a lion climbing a tree except to avoid the dogs. They tirelessly hunt and stalk their quarry on the ground, taking advantage of every cover, and finally rushing from a distance of 40 or 50 feet. This distance is covered in about a second. A 100-pound lion moving at a velocity of 40 feet per second will strike a blow sufficient to prostrate a yearling steer. The heavy muscles of the lion’s neck, shoulder and forepaws are tense for the blow, and easily absorb the shock that prostrates his unsuspecting victim, which is then killed by being disemboweled. The liver is eaten first, and then the loins and hams. An examination of probably 100 deer killed by lions showed no evidence of the lion having touched the throat of any of these kills. I have found the lion to be normally a solitary and invariably a silent animal. J have never heard that hair-raising scream the lion is sup- posed to utter, and I do not believe it makes any loud sounds, but that the noises usually attributed to it are made by owls and coyotes. On one occasion of which I know, about fifty guests at a mountain resort were listening one evening to the braying of a mule colt, and were told in good faith that they were hearing a mountain lion scream. Every one of these people, including their informant, probably believes to this day that they were hearing a lion. Some writers have condemned the mountain lion as being cowardly and unwilling to attack in the open, but they lose sight of the fact that the cat family is short-winded and unable to capture its prey by running it down as the dog family does. If the lion should openly approach his prey and challenge it to combat, his intended victim would imme- diately take to flight, leaving the lion to go hungry. His only means of making a living is to surprise his quarry. In a fight to the death, the mountain lion is more game than the black bear. He will fight with his last breath, when the black bear will quit and cover his head with his paws and bawl like a ealf. The most reliable method of taking lions is trailing with dogs, and the best dogs for this purpose are fox hounds.
