TROUT-BREEDING IN WINTER 1 75 



are many gentlemen who sell ova, or eggs, they 

 may be procured without difficulty,! and I will 

 therefore commence from the period when the 

 eggs are actually in progress towards hatching. 



The apparatus first commands our closest atten- 

 tion. A constant stream of water is indispensable 

 at the outset, and the next requisite is a suitable 

 box or boxes for the reception of the ova and the 

 fry when they appear. Neither of these is diffi- 

 cult to obtain. 



As to the water. If it be possible to join on a 

 pipe to the water-works' supply, and regulate the 

 stream of water by means of a tap, then half the 

 battle is won ; but as it is not likely that boys will 

 care to purposely go to this expense, some other 

 device must be thought of. A cistern, or even 

 tub, if clean and sweet, will do to store the water 

 in, if the latter is pumped from a well ; and it 

 should be indoors, out of the reach of frost, and 

 raised above your boxes or troughs. It need 

 not necessarily be very near, for a small India- 

 rubber pipe will convey all the water.

 eggs and fry in the proper season.
