154. Hatching table, in three parts, showing models of the various kinds of 

 hatching apparatus used in the United States, in actual working order, the water being supplied 

 by means of a gas pumping-engine which forces it into closed pipes with a pressure of 15 Ibs. to 

 the square inch. Stop-cocks are placed at frequent intervals in these pipes, and are connected 

 with the hatching apparatus by means of rubber tubing. The apparatus is supplied with 

 natural and artificial eggs to give a better idea of its workings. The first compartment contains 

 the closed apparatus, the next the trough and other apparatus requiring running water, while 

 the third is arranged as a basin or artificial lake for showing the floating apparatus and other 

 kinds used in open streams. A McDonald fish- way is placed at the end of the table to conduct 

 the waste water to the tank below, from which it is again carried to the pump. 



155. A figure representing a man in the act of taking eggs from an Atlantic 

 salmon in a pan in which they are to be impregnated. By his side are casts of a ripe male and 

 female salmon with the abdominal walls removed to show the ovaries and spermaries in position.

 aquaria, a reservoir tank provided with filters, and a porcelain-lined sink. Model of hatching 

 house at United States salmon-breeding station at Bucksport, Maine, built under the direction 

 of Mr. Charles G. 'Atkins, with movable roof for showing the interior, which is provided with 

 troughs for hatching eggs of the Salmon. The water enters the troughs through a feed-pipe 

 extending along the side of the room and escapes by pipes through the floor. Model of United 

 States hatching house at Northville, Michigan, built under the direction of Mr. Frank N. Clark, 

 for hatching eggs of Lake Trout, Brook Trout, California Trout, California Salmon and White- 

 fish. The interior of this hatchery is provided with miniature hatching troughs and jars, while

 important hatching stations of the United States Fish Commission, including the national Carp 

 ponds at Washington, District of Columbia, the United States reservation for fish-cultural pur-

 fish-cultural work, such as taking and impregnating the eggs, tagging the fish, and the process 

 of manipulation of the eggs and young fish at the hatchery.
