Trout Breeding. 41 



and a coat of spar varnish makes it bright and attract- 

 ive. When I began operations at Cold Spring Harbor, 

 N. Y., in January, 1883, I had an old brick house, 20x 

 30, on the hill ; the water from there went into an old 

 tumble-down wooden building of the same size and A 

 water from a lower reservoir, and it was practically a <_ 



ifed troughs on the upper floor, while below we took3 H 

 three-story hatchery. Then, when the brown trout eggs ^ 

 came from Germany I had to put troughs outdoors and 

 give them water from tne lower floor. It was all hastily 

 improvised, for there had been no time to prepare for the 

 work ; but I had then fifteen years' experience and knew 

 how to care for the eggs until troughs and trays could 

 be made. 



Salmon eggs came in crates from Maine, trout eggs 

 from Caledonia, N. Y., and from Germany, which 

 taxed the new hatchery beyond its capacity; but I 

 brought over a lot of poor troughs from Roslyn, made 

 under like conditions the winter before for salmon 

 work, and had more made. The only eggs which were 

 injured by this imperfect preparation were some that 

 were in the outdoor trough, where frost and visitors 

 interfered. One night the frost choked the outlets on 

 the upper floor of the wooden building and the water 

 overflowed the troughs and froze two feet thick on the 

 outside of the building, so that we had to chop the ice to 

 open the door. The eggs were heavy and received no 

 damage, but it was fortunate that the water supply was 

 not stopped. 



The hatchery may be an inexpensive shed, but the 

 floor should be solidly supported, so that there is no 

 jar to the troughs when people walk about. Windows 

 should be plenty, but provided with heavy roller shades, 

 preferably, of a green color, so that light may be had
