our native brook trout, the brown trout, or common brook trout 

 of Europe, and the rainbow trout of California. The trout for 

 distribution are sent out when about ready to take food in March 

 and April. Those to be kept at the station for breeders are fed in the 

 troughs for a month or more, and are then put in the " baby ponds." 

 These are of two-inch yellow-pine sides and one-inch bottoms, 

 twenty-five feet long, three feet wide, and about twenty inches 

 deep, with a strong flow and double screens of No. 8 wire cloth, 

 between which is a dam an inch higher than the pond below. In 

 these ponds are " rests," made of projections from the sides or of 

 dams, with a surface stop- water a few inches below them, which 

 causes the water to flow up and over the dam, and is then again 

 deflected below. This keeps weak fish from being swept against 

 the screens, and makes eddies for the food to swirl about in, in- 

 stead of sinking. Mr. Hoxsie has patented an ingenious device to

feed young fish in, and it is somewhat different from this plan 

 which I used at Honeoye Falls, N. Y., in 1874 and since. Of these 

 " baby ponds " we have ten, and, as we put ten thousand fry in 

 each, we start in with only three of them stocked ; but the little 

 fellows have a way of getting around screens that are supposed to 

 be tight, and before they are an inch and a half long some are found 

 in the lower ponds, having gone through joints in the planks or 

 sides or bottom, or around some loose screen, if not through a neg-
