day after the first lot was spread the water in the pond 

 was raised sufficiently to cover this lot and on each suc- 

 ceeding day it was raised until the pond was full and the 

 last lot of manure covered. 



By June 10th, 3,000 young bass from an inch to an 

 inch and a quarter long, which had been collected from 

 other rearing ponds, were placed in this pond. From 

 it, up to August 31st, 2,800 fingerlings from 2 to 2% 

 inches long had been secured for distribution and during 

 September about 100 more 3 inches in length were col- 

 lected. All of these fish made excellent growth and were 

 in fine condition when shipped. They were given no 

 other food. 



This experiment is considered eminently satisfactory 

 and will be repeated next year. 



In pond G, 45/100 of an acre in area, and which is sup- 

 plied largely from small, bottom springs, 7,000 bass from 

 an inch and a quarter to an inch and a half in length 

 were placed, within a day or two of the introduction of 

 fish into Pond D. Pond G had not been previously 

 manured but the natural food it contained was supple- 

 mented to some extent by occasional feedings of a grounc 

 animal food purchased in Chicago and which is used at 

 this station for feeding young and old fish. From this 

 pond only 750 fingerlings were secured but they were 

 from 3 to 4 inches in length and, of course, fat and in 

 excellent condition. They had attained this condition by 

 feeding on the other 6,250. 



Mention of the Chicago food has been made. Repeated 

 experiments at this station have proved that this is not 

 a satisfactory food for bass under 2y 2 to 3 inches in 

 length, although they take it fairly well after that size 

 has been reached. Even at this 3-inch size, however, 

 they much prefer finely chopped mullet.
