The first attempt at artificial trout-culture in America was made inOhio in 1853 and marked success attended the efforts. Further satis-factory trials were made in 1855 and 1859 in Connecticut and New York,and in 1864 a hatchery was established in New York which became apractical success in carrying on the work on a large scale. Somewhatlater the work was taken up by the State and United States govern-ments and is now very extensively carried on in all parts of the UnitedStates. The methods described in the following pages are those which havebeen found advantageous at the Northville station, and are there pur-sued. In addition to the eggs obtained from brood fish held in pondsat the hatchery a field station for collecting eggs from wild trout isoperated on the Au Sable Biver. Report U S. F.

MANUAL OF FISH-CULTURE. 95 THE FIELD STATION. For the egg-collecting station a point was selected, on a tributary ofthe An Sable, flowing about 1,000 gallons per minute, near where itempties into the river. A dam was thrown across the stream and 100feet above a screen was built to prevent the fish from escaping in thatdirection. The dam is simply constructed by banking up mud, sand,aud turf, and has a frame sluiceway 3 feet long, 2 feet wide, and 2 feetdeep. In the sluiceway is inserted a double screen of J-inch mesh wirenetting, two screens being necessary to keep the overflow clear andreduce as low as possible any loss of fish through this outlet. Theinclosure accommodates about 10,000 fish. For holding the eggs twopairs of troughs are placed on standards driven into the bed of thestream, with a passage between them wide enough to admit a man.Fish are obtained with rod and line, until they begin to run from thedeep pools upon the spawning-grounds, when much better results areobtaine
