 full, and then they are put in the box. As the bottom 

 of one rests on the top of the other the eggs are kept in 

 place. Such a box will hold an immense number of eggs, 

 but is only suited to being sent by a messenger who will 

 take charge of it, and cannot be trusted to express.

Appeaeance. — After the eggs have lain in the water 

 from fifty to seventy-five days, according to the temper- 

 ature, the Trout will begin to make their appearance, the 

 egg appears to be endowed with life, and the motions of.
