IMPLEMENTS. 



eg^s in our liatcliing house, not a half dozen got it right 

 until told how to do it. The microscope need not be rery 

 strong ; one magnifying eight or ten diameters is amply 

 sufficient. A small net will be of use in removing the 

 young fish from the troughs ; it should be about 6 inches 

 in diameter, in the shape of the letter D, with the handle 

 on the middle of the bend. It is very easily made by bend- 

 ing a wire in the desired shape, and twisting the two ends 

 together for a handle. Thin gauze of some kind should be 

 spread over the wire so tightly that the middle of the net 

 shall hang only a half inch below the level. An iron spoon, 

 well tinned or silvered, is used to remove the eggs. Some 

 six-quart tin milk-pans will be necessary, for a variety of 

 purposes. Eggs may be counted most easily by measuring 

 them. For this purpose take any small glass, such as a 

 very small tumbler, for instance, count out 500 or a 1,000 

 eggs, and with a file make a mark upon the glass as high 

 as they reach, and the measure is always ready to your 

 hand.
