208 Modern Fishculture in Fresh and Salt Water. 



Only by the microscope could one see that the egg of 

 a smelt was adhesive, but not glutinous. As I un- 

 derstand it, a glutinous egg has some sticky envelope 

 which attaches anywhere it strikes. The egg of a 

 smelt throws out a sort of "foot stalk," which acts like 

 a sucker in attaching it to objects; hence the distinc-

 my vocabulary. 



The old plan was to work the eggs by hand, through 

 sieves, and by more or less violent means rub off the 

 mucous coating. Messrs. Nevin, Clark, Page and oth- 

 ers hit on the use of earth or clay about the same time, 

 and Prof. Reighard, of the Michigan Commission, 

 found cornstarch to be excellent for this purpose. I 

 had no occasion to try these things, for the only ad- 

 hesive eggs which came my way were those of the 

 smelt, which has a foot stalk like a wineglass, but 

 seems to be capable of throwing this out from any side, 

 and to do it again after one is broken off.

This small whitefish, Coregonus quadrilatcralis, is 

 a round-bodied fish, as its specific name implies; also 

 called "round fish," "shad waiter" and "Menomonee 

 whitefish;" comes out of the deep waters to spawn in 

 the streams in the fall and is caught in great numbers 

 and salted for winter use. It ranges from northern
