Wytheville Station, Virgixia (Gteorge A. Seagle, Superintendent). 



All of the fish hatched tiie previous spring having been disposed of, 

 in order that the station might be thoroughly overhauled and remod- 

 eled, the employees were occupied during the summer in caring for the 

 adult fish on hand and assisting in the general work of construction. 

 In addition to rebuilding the old ponds IS new ones were added, making 

 a total of 42. The present system for trout comprises 8 stock-ponds 

 and spawning-ponds 15 feet by 48 feet by 3.^ feet, and 14 rearing-ponds 

 varying in size from 10 feet by 50 feet to 15 feet by lOG feet, and from 

 inches to 5 feet in depth. For the basses and crappie 4 breeding-ponds 

 and 15 rearing-ponds have been provided, and 1 pond for carp. 



In constructing the trout ponds several minor improvements were 

 made. In addition to providing the spawning-ponds with raceways 4 

 feet wide by 20 feet long by 1 foot deep, a receiver 2 feet by 4 feet by 2 

 feet was built at the foot of each pond between the guard-screens and 

 the dam-boards, over which was set a grating in the space where the 

 bottom was cut away. In this receiver excrement and other foul matter 

 settles after i^assing from the pond through the guard-screen, and before 

 washing over the dam board into the raceway leading to the next pond 

 below. This receiver is connected with a large sewer or waste-pipe of 

 8 inch terra cotta, which is closed at its mouth by a sliding gate arranged 

 so that it can be drawn out to flash and clean the receiver and pond; 

 by this means all foul matter is carried off through the flush-pipe 

 without passing into the next pond.
