cate, say for the first fortnight, and I have put stones 

 and bricks in the troughs to induce them to scatter. But 

 these are not good ; some will wedge their heads under 

 them and die. If kept dark by covers, as aforesaid, for 

 a couple of weeks they will come out right, for the 

 crowding is merely to escape light, and when the covers 

 are lifted the little fellows which were quiescent begin 

 to scatter to find a dark place. Under this management 

 the strong fellows will be well up in the trough and 

 the weaklings and deformities will be sifted out by the 

 incessant working of their tails to keep their places and 

 will be found about the foot of the trough ; crooked

To PREVENT FRY FROM CROWDING. This is a small inner frame 

 to place in the trough. BB, outer and inner troughs; F, 

 an inner projection of wood or tin; W, wire cloth through 

 which water from the outside flows. By W. P. Seal in 

 Forest and Stream, Feb. 19, 1891. The fry are supposed to 

 gather below the wire cloth W. 



tails, double-headers and all others not fitted to survive 

 will be found near the outlet. 



The newly hatched trout is much more delicate than 

 the egg and must be treated accordingly. Move them, 

 when necessary, by pouring water on them or by mak- 

 ing currents with a feather, but don't touch them. If 

 you wish to disturb them to remove the dead or to send 

 them toward the head of the trough take, a piece of half-- 

 inch pine board, a little less than the width of the trough 

 and one inch less than its depth ; tack a strip on its 

 upper edge to rest on the top of the trough and slide this 

 down the trough with some force. The water will rush
