108 OLD FLIES IN NEW DRESSES 



presented some trout to the Brighton 

 Aquarium. I myself caught some of these 

 trout, which were put in a rearing pond to 

 await their being transferred by rail to 

 the Aquarium. As I also assisted in the 

 operation of taking them from the rearing 

 pond and putting them into the tanks in 

 which they were to travel, I can vouch for 

 their size at that time. They were all in 

 rather bad condition, and, even had the 

 largest been in good condition, it could 

 not have weighed more than three-quarters 

 of a pound. These trout have been fed 

 entirely on Crustacea since they were intro- 

 duced into the tank they now occupy ; and 

 at the time I am writing (January, 1898), 

 the largest of these trout must be quite 

 two pounds or more in weight, and there 

 are others which are nearly as large. 



The voracity with which these trout 

 seize the Sandhoppers and Shrimps upon 

 which they are fed is a perfect revelation. 

 I have seen them leap out of the water to 

 catch the Shrimps thrown to them before 

 they reached the surface. 



I have also found that young trout in 

 rearing ponds take Fresh-water Shrimps
