29.4 PACIFIC SALMON FISHERIES. 
In 1895 another hatchery was built by the State near the mouth 
of Battle Creek, a tributary of the Sacramento River. In 1896 and 
1897 this hatchery was operated jointly by the State and the United 
States Fish Commission while awaiting the appropriation of money 
by the Commission to purchase it from the State. 
In the fall of 1897 a hatchery was established by the State at 
Grizzly Bluff, on Price Creek, a tributary of Eel River, in Humboldt 
County, and in 1902 this hatchery made the first plant in the State 
of steelhead trout fry. 
Santa Cruz County has had a hatchery at Brookdale for a number 
of years. In 1911 it was leased to the State and operated by the 
latter during the seasons of 1911 and 1912. In 1913 the State gave 
up the lease and entered into a contract. to purchase the eggs pro- 
duced from this hatchery. The price agreed upon was that the 
State Commission was to pay $1.50 per thousand for the eyed steel- 
head eggs, up to the number of 2,000,000, and $1 per thousand for all 
eggs up to 3,000,000, provided that the eggs were collected and eyed 
by a skilled fish culturist and would pass inspection before they were 
accepted. 
A hatchery was established by the United States Bureau of Fish- 
eries at Hornbrook, on Klamath River, in 1913. At first this hatch- 
ery was devoted to rainbow trout work, but later the collection and 
distribution of silver and chinook salmon was taken up. 
During the fall of 1911 the State established an experimental 
station at Sacramento in order to carry on a series of experiments to 
determine whether the eggs of the quinnat salmon could be success- 
fully hatched and the fry reared near the city of Sacramento. Of 
the fish hatched at this station 50,000 were marked. 
Nearly all of the fry that were liberated in the Sacramento River 
were floated in a screen cage by boat into the middle of the stream 
and there released. N. B. Scofield 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 apparently not affected by the changes 
in the salinity of the water. 
Experiments were carried on until the summer of 1913, when 
they were abandoned due to the killing of the embryos by the min- 
eral substances in the water used at the station. 
During the fiscal year 1912 the Mill Creek hatchery of the United 
States Bureau of Fisheries was operated by the California Com- 
mission. 
Some years ago the town of Ukiah, Mendocino County, estab- 
lished a hatchery 1 mile from the town, and on Russian River. 
For some years it was operated as a trout station, but eventually . 
became an important steelhead hatchery. It was not operated in 
1913. In 1914 the State Fish Commission collected steelhead eggs
