40 TROUT CULTURE. 



much as possible of the moss and all the heavy parts 

 of it having been removed, the whole arrangement is 

 to be carried under a tap and a gentle stream of water 

 directed to one side of the vessel ; this will drive over 

 the moss, with the assistance perhaps of a feather, and 

 the eggs will settle in a state of purity ; they may then 

 be quickly transferred to a trough, or be washed further 

 in any other vessel, as may be convenient. 



When muslin is used, the moss is cleared away till 

 the muslin appears, and all moss adhering to it is 

 removed ; then the edges are folded together, and the 

 whole lifted out and skaken, and gently separated in a 

 vessel of pure water ; the eggs sink, and any floating 

 moss may be driven over as before, after all the layers 

 of eggs have been shaken out in the water. 



In sending eggs away the reverse operation is per- 

 formed. The tin is sunk in a vessel of water, then a 

 layer of soft,, well-washed Sphagnum moss is put on 

 the bottom, then one fold of muslin, then the eggs are 

 carefully distributed over this with a glass tube, and 

 arranged with a feather or thin glass rod, so that no 

 two eggs are in contact, then a second fold of muslin, 

 and the operation repeated as before till completed. 

 Next, a good thick layer of moss is put on and the box 

 drained ; then, should the moss have sunk down, it is 

 topped up with a fresh layer to completely fill the box, 

 and the lid is put on. Finally the tin is packed firmly 

 in sawdust, in a wooden box, the lid screwed down, 

 and sent off. 



In estimating the number of eggs in a fish, the rule 

 is that one thousand eggs go to a pound of weight. 

 Thus a half-pound fish will have five hundred, or 

 nearly so ; a pounder, one thousand ; a two-pounder, 

 two thousand, and so on.
