mission. This apparatus consists of a cylindrical tin can, the 

 bottom part of which has sloping sides, the top beiug provided 

 with a wire-cloth strainer and tin spout, to enable the water to 

 be more easily poured. It has handles for convenience in car- 

 rying. Designed for use in boats when carrying shad-eggs 

 across rough water, the sides being high to prevent slopping. 



Taylor's egg-transportation can. 



Height, 19£ inches ; diameter, 13 inches. Invented by Thomas 

 Taylor^ Newberne, K. C, 1878. 57,153. U. S. Fish Commis- 

 sion. The can is provided with pans or trays for holding the 

 eggs. In the center of the can, extending from top to bottom, 

 is a supply tube, an inch in diameter, with holes opposite each 

 tray. This tube extends upward between the tray and cover, 

 water being introduced at the top by means of a funnel passing 

 out through the jets upon the eggs, and dripping through the 

 different trays to the bottom of the can, where it escapes through 

 numerous small openings around the sides. This apparatus has 

 been successfully used in the transportation of shad-eggs from 

 distant fishing-shores to the hatchery. It marks the transition 

 period between the old, or wet, and the new, or dry, method of 

 transportation ; for by it water was thrown upon the eggs at 

 frequent intervals, though they were not at any time immersed 

 in it. 



McDonald's egg-transportation crate. 



A crate containing eighteen shallow trays or wooden frames, with 

 wire-cloth bottoms, incased in canvas, and secured by frames 

 connected by leather straps. Length, 16 inches ; height, 15 

 inches ; width, 14 inches. Invented by Marshall McDonald, 

 May, 1881. U. S. Fish Commission. 57,150. This crate is 

 used for transporting the eggs of the shad for a distance of 50 

 to 100 miles. The bottoms of the trays are covered with wet 

 cloths, upon which the eggs are spread. Each tray holds from 

 10,000 to 15,000 shad eggs. When filled, they are incased in 

 the cloth cover, securely strapped together, and shipped by 

 boat or rail to the hatchery. This apparatus marks the begin- 

 ning of the dry transportation of shad eggs, and has been suc- 

 cessfully used in the work of the U. S. Fish Commission for 

 the past two years.
