ing covered with wire cloth to admit of circulation of the 

 water. On either side of the can is a tube of tin extending 

 through the upper bottom. One of these has a funnel-shaped 

 top and serves as a feed-tube for introducing fresh water; the 

 other is provided with a pump by means of which stale water 

 can be removed. Diameter, 9£ inches ; height, 10 inches. In- 

 vented by Cbarles W. Eogers, Waukegan, 111. 26,281. Pre-

Automatic transportation can. 



A cylindrical can of copper, with contracting neck to prevent splash- 

 ing, and a movable cover, the center of which contains a brass 

 plate with tubular openings, through which the water enters 

 and escapes. Height, 18 inches; diameter, 14 inches. IT. S. 

 Fish Commission. 57,175. To the inner end of the outflow- 

 pipe is attached a wire frame, covered with cloth, which serves 

 as a strainer to prevent the escape of the fish. The outer end 

 of the other tube communicates with a reservoir of water by 

 means of rubber tubing. When several cans are fed by the 

 same reservoir they are placed side by side and so connected 

 that the water passes readily from one to the other.

 U. S. Fish Commission. 57,174. To the inner end of the out- 

 flow-pipe is attached a wire frame, covered with cloth, which 

 serves as a strainer to prevent the escape of the fish. The 

 outer end of the other tube communicates with a reservo'r of 

 water by means of rubber tubing. When several cans are fed 

 by the same reservoir they are placed side by side and so con- 

 nected that the water passes readily from one to the other. 

 Cans of this size hold about 20,000 shad. 



Carp transportation can. 



A cylindrical tin can, incased in wood, with the top slightly con-

 inches; capacity, 10 gallons. U. S. Fish Commission. 57,172. 

 This can holds from 30 to 50 carp 3 inches in length. It was 

 formerly extensively used in the transportation of this species, 

 but it is now seldom employed, as small pails are found more 

 convenient, less expensive, and equally satisfactory.
