The Transport of Live Fish. 125 



Land and Water, in which a number of 

 adult specimens of salmon, perch, black bass, 

 etc., were conveyed from the Atlantic to the 

 Pacific Ocean, from New York to California. 



The fish were carried in a waggon fitted up 

 expressly for the purpose, and belonging to 

 the United States Fish Commission. Bound 

 the waggon are ranged tanks to hold the fish, 

 of a convenient size for moving about in 

 transit. Each has a siphon of india-rubber, to 

 allow the water to be drawn off and renewed, 

 when necessary, without disturbing the fish. 



A special arrangement provides for aerating 

 the water during the journey. On one of the 

 axles of the waggon is fixed a wheel, which, 

 by means of an endless belt, drives an air- 

 pump, which is worked constantly while the 

 train is in motion. The air is forced into an 

 india-rubber tube having a branch to each 

 tank, each branch being fitted with a stop- 

 cock, to regulate the supply of air. By the 

 aid of this ingenious arrangement, more than 

 150 breeding fish, of nine varieties, were 

 carried without serious loss across the 

 American continent. For the sea fish, a 

 supply of sea-water was sent from California
