FOR PLEASURE AND PROFIT. 149 



the attendant may stand when feeding the fish. Twenty 

 thousand fry are stocked to each box, and they are 

 fed three times a day much as other trout fry are. I have 

 had twelve of these boxesi for five years in a mill-stream, 

 exposed to very strong freshets, and I find that each box 

 turns out from 12,000 to 17,000 two-inch healthy rainbows 

 in May. I haive kept fry in them for experiment sake till 

 October (thinning them down to 5,000); but, although the 

 fish kept healthy, and fed well, they turned out in the end

undersized and uneven. I haiv hatched fully-eyed ova in 

 these floating boxes, hanging up perforated trays two inches 

 from the bottom, and have done quite well with them. The 

 boxes require a fairly strong stream, the stronger the better, 

 and keep the fry wonderfully compact for feeding, and pro- 

 tected during their babyhood. I should think where proper 

 attendance cannot be secured the boxes ought not to be 

 tried. Where the boxes can be worked by a skilled atten- 

 dant on some side-stream to the main body of water, they 

 will cenbainly prove a. chearp and effective way of planting 

 rainbows, the fully-eyed eggs only having to be bought and 

 hatched on the spot."
