hatching apparatus generally in vogue in that country, 

 as communicated to me by Professor Easch. 



The case in which the hatching-boxes are placed 

 (and which is under shelter, so that the water does not 

 freeze) is twelve feet long, thirty-four inches wide inside, 

 and five inches deep. The bottom must be perfectly 

 water-tight, and very evenly planed. The sides are 

 formed of single smooth-planed boards, which fit tightly 

 against the bottom, to prevent any leakage ensuing. 

 The uppermost end of the case, and into which the 

 water runs from the pipe, is of the same height as 

 the sides. The whole is divided into five compart- 

 ments, the first of which receives the water from the 

 pipe. This compartment is eighteen inches wide, while 

 the other four are each thirty inches wide. The 

 partition boards are one inch lower than the sides of 

 the case, and have holes bored in them at a distance 

 of two inches from the bottom, by means of hot wire. 

 They are bored in two rows (vide fig. 1.), four below, 

 and three above. The water can thus run evenly 

 throughout the length of the case. 



The hatching-boxes (fig. 2), four of which are placed 

 in each compartment, are constructed as follows : 

 The sides consist of smooth-planed board, two feet 

 long, three inches high, and an inch and a half thick. 

 The bottom is a glass plate, two feet long, and seven 

 inches wide. The ends are of perforated zinc, or brass
