112 PISH HATCHING. 



when carried out on a large scale in the beds 

 of rivers, are really most important as regards 

 our British salmon fisheries. All my eggs 

 (salmon, trout, salmon-trout, and charr) soon 

 hatched out, and the glass rods upon which 

 they were placed became idle. The whole 

 batch of salmon-trout were gone by February 

 4, leaving a mass of empty egg-shells in the 

 water ; and the young fish, which have fallen 

 through on to the gravel underneath, were as 

 healthy as possible. They are curious little 

 fellows are these baby salmon-trout. I can 

 see no difference when they are just hatched, 

 between them and the common trout, except 

 in their colour. The mass of young salmon- 

 trout look like a number of drops of the 

 yellow barley-sugar ; the common trout, on 

 the contrary, are much more pale in colour
