40 FOOD HARD TO KEEP. 



others, they will swallow each other whole. We have 

 taken a Trout one inch long out of another only two inches 

 long. It would seem to be advantageous, therefore, to 

 sort them out every little while, and put the same size by 

 themselves ; but in practice this is very difficult, and the 

 less a Trout of any size is handled, the better ; besides, if 

 they are fed well, they lose their disposition to eat each 

 other. Therefore, the Trout of each year may be left by 

 themselves with very little probability of losing more by 

 cannibalism than would be killed in sorting out and re- 

 moving. 



The covers should be kept on the first pond at night, 

 and in dark, cloudy weather until September, at least, 

 when the Trout will be from two to five inches long and 

 able to take care of themselves. Even then it is as well to 

 have the covers at hand and put them on in case of a rain 

 storm, since we often find after a storm numbers of young 

 fish dead in an exposed pond ; therefore, we conclude, 

 although we do not know the philosophy of the thing, that 

 they need a cover in rainy weather. After September 

 there is no difficulty in raising the fish — they all appear 

 hardy and strong ; perhaps it is because all the weak ones 

 have died ofi", and none are left but those able to " stand 

 the pressure." 



Hard to Keep. — There will always be a difficulty in so 

 arranging ponds, screens, outlets and inlets as to keep 

 the young fry in their proper pond. The water is very apt 

 to work holes around the screens, or rather around the 

 boxes containing the screens.. The young fry will work 

 their way through a wonderfully small hole, no matter how 

 long the distance may be. They will also get through be- 

 tween the screen and the socket, unless they are very well 

 fitted together, and worse than all, wherever there is a 

 crack into which they can get their large heads, they will
