were afterwards mixed with others and the whole lot 

 i-oiighly handled before an opportunity was had of making 

 a careful examination of them. The susj^ension of opera- 

 tions shortly after this prevented a rej)etition of the ex- 

 periment. 



It is to ha noted that when the eggs are permitted to 

 adhere to the pail and to one another, so that the percentage 

 of those injured is large, the percentage of those impreg- 

 nated is also greater. The same method of handling that 

 reduces the percentage of injured eggs reduces also the i^er- 

 centage of those unimpregnated. 



From the two causes about 45^ of the eggs examined 

 could never have developed. Since the percentage of eggs 

 lost during the present year is estimated at 40, there 

 remains 15^ still to be accounted for. 



A lot of eggs, 45^ of which are dead, requires much 

 more handling than would be the case if all were sound. 

 Such a lot of eggs also invites the attacks of the fungus 

 which spreads from the dead eggs to the living ones, and 

 is likely to kill those in turn. 



In such a lot many living eggs become clogged among 

 the dead ones, and are probably either smothered or 

 poisoned. 



In short, if the loss of eggs which takes place at first 

 from mechanical injury and lack of impregnation can be 

 stopped, it is fair to expect that the subsequent loss will 

 be much reduced. 



THE STURGEON; SOME EXPERIMENTS IN 

 HATCHING.

Of the numerous lish which abound in the great lakes 

 and deep rivers that surround the State of Michigan, one 

 of the most valuable, commercially, is the sturgeon. 

 Nearly every part of it is utilized in some way ; the flesh
