and are assuming a different color from those that arc being fed 

 on Hver; the tails and fins arc becoming highly colored. I think 

 this also partly settles one of the -mooted (|uestion§ in reference to 

 planting partially-reared fish, that fish raised on liver from six 

 to eight months and then planted, would starve to death before 

 they would accustom themselves to their changed environment 

 and to finding their own natural food. So much in answer to 

 the question that T was unable to answer a year ago. Now to 

 our 'work of collecting wild brook trout for spawning purposes, 

 on the An Sable river. This was undertaken by the United 

 States Fish Connnission in the fall of 1895; men were dispatched 

 to this river late in August and a camp was formed on a branch 

 that had been previously Leased ]:>}• the L'nited States Msh Com- 

 mission for the purpose of building ponds for temporary use for 

 holding trout. I quote from the report to the United States Fish 

 Commission in reference to these ponds: 



"A dam was thrown across the stream and too feet above 

 a screen was built to prevent the fish from escaping in that 

 direction. This dam was simply constructed, being built of mud, 

 sand and turf banked up, and had a frame sluiceway 3 feet long. 

 2 feet wide and 2 feet deep, with the necessary double screen put 

 in the overflow to prevent the passage of fish below, making 

 an inclosure about 100 feet long by an average width of 12 to 15 

 feet. This inclosure accommodates about 10.000 fish.'" 



The fishing was commenced with rod and line soon after the 

 camp was established, and occasionally with the seine, to collect 

 fish in that manner. The rod fishing was continued until about 

 the 1st of October, when the trout commenced running on the 

 beds, and then the seine was used exclusively. 



The first season there were taken from the stream by rod and 

 line and also by the seine, upwards of 6,000 trout ; from these in 

 the neighborhood of 400,000 eggs were taken ; the first eggs being 

 taken about the ist of October. These were placed in troughs 

 that had been previously arranged. 



As soon as ripe fish are found among those caught on the 

 spawning beds, the pond is hauled with a seine and the fish are 

 looked over twice a week until all the eggs are taken. When the 

 season is fairly opened the spawn may be taken from most of the 

 fish immediately after they are caught, thus obviating the dififi- 

 cultv of transferring them from the ]:ioint of capture to the pond ; 

 in some cases a distance of three or four miles. T quote from 

 mr former report in describing the troughs used ; 



"The water is received through two one-inch orifices in a
