 SCHOOL OF MINES. 



3733 EARL DUCIE: Do you know what the habits 

 of the salmon are in the sea upon what he lives? There 

 is much reason to believe that those animals live chiefly 

 upon entomostracous crustacese, which are found in the 

 sea in very great abundance. I believe that is one 

 reason of the great increase of size which the salmon 

 attain in the sea ; because in the rivers the only food of 

 this kind they can obtain consists of insects and insects' 

 larvae, which are comparatively few; but directly they 

 come to the sea there are great patches of water where 

 crustacese are found in abundance. 



3734 In fact, they swim in a species of animal soup? 

 Yes. 



3735 EARL CAWDOR : Are those crustacese found in 

 deep water? Yes, it would be quite possible for the 

 salmon to obtain such food there. 



3736 EARL DUCIE : What depth are the crustacese in 

 the water? They are at the surface in deep water. Very 

 often you find the surface completely thick with them. 



3737 One of the witnesses has stated it as his belief 

 that the principal food of the salmon is the ova of the 

 echinidse? I doubt that very much. I do not know 

 how the salmon are to get them to begin with. If you 

 examine the surface of the sea, you find the embryos 

 of echinodernus mixed up with other things, and there 

 is a far greater multitude of minute crustacese and mol- 

 luscs. The salmon can only open his mouth and take 

 what comes into it; he cannot separate them. You do 

 not get the ova or embryos of the echinidse in distinct 

 patches by themselves. 



3738 Those ova are not deposited at the bottom of the 

 sea? No ; the ova are very rapidly hatched, and as soon 

 as they are laid they become fry or swimming embryos.
