J. PISCICULTURE AND THE FISHERIES. 429 



The batching boxes constitute an essential feature of the 

 operation, and are constructed according to a plan patented 

 by Mr. Green. These are made of wood, are nineteen inches 

 long, thirteen inches wide, and ten inches deep, open at the 

 top, and the bottom composed of tarred wire-cloth of twenty 

 meshes to the square inch. Each box has fastened to its sides 

 two wooden floats, holding it in the water at an angle of for- 

 ty degrees, so as to subject the eggs to the action of a slight 

 tidal current, it being necessary that the eggs should be kept 

 in a gentle and continuous motion until hatched. These 

 boxes are fastened together, one behind another, in rows of 

 five or six, with an anchor at one end of each gang, in order 

 that the boxes may adjust themselves to the tide. 



In twenty-four hours after impregnation, with a tempera- 

 ture of 75, a small yellowish speck is visible in the circum- 

 ference of the yolk within the egg. Forty-eight hours later, 

 at the same temperature, the young fish is visible in active 

 movement within the egg, and from which, in a short time, 

 it succeeds in escaping. The fish, on leaving the egg, is half 

 an inch long, with an umbilical sac attached, which is ab- 

 sorbed in from six to eight days, during which period it is 

 kept in the boxes ; after this it is liberated into the stream to 

 find subsistence for itself. Albany Argus, June 25,1872. 



PLANTING OF SHAD IN THE GENESEE ELVER. 



Mr. Seth Green, of New York, continues to be indefatigable, 

 under the direction of the New York Fish Commissioners, in 

 his efforts to stock the waters of that state with useful food 

 fishes. Last year he introduced about 15,000 young shad 

 into the Genesee River, and finds that they have already at- 

 tained a considerable length. During the present year he 

 proposes to transport 100,000 young shad from the Hudson 

 into Lake Champlain, and hopes in this.instance for an equal- 

 ly satisfactory result of his experiment. Lake Champlain 

 now possesses a fish known along its shores as the shad, but 

 which really is a whitefish, and not the species bearing the 

 first-mentioned name on the Atlantic coast.
