POULTRY. 



561 



years past considerable improvement has been made in incubators, until we have them now 

 that are so simple in construction, that they can be successfully managed with comparatively 

 little labor and expense. 



An incubator that will hatch from seventy to seventy-five per cent, of the eggs, may be 

 considered a good one. As with the hen, the fresher the eggs, the better they will hatch. 

 Eggs that are over a week old, will, as a general rule, hatch very poorly by artificial heat. 



ECLIPSE INCUBATOR. 



&quot;With the hen, there is considerable loss by eggs broken in the nest, and nests deserted from 

 one cause or another. Again, the e,ggs of different breeds of poultry vary greatly in fertility, 

 while the eggs of the same breeds will also vary much in this respect. 



In the Eclipse Incubator, manufactured by E. A. Samuels, of Waltham, Mass., the heat 

 is radiated from a tank which is so contrived that there is a uniform circulation of hot water 

 through it, and is applied to the top of the eggs in imitation of heat from the hen. The eggs 

 are placed in drawers, the bottom of which consist of wire netting. Beneath the drawers is a 

 series of ventilating pipes, which conduct to the bottom of the eggs a full supply of cool, 

 damp air. The water in the tank is heated by a kerosene oil lamp, which consumes only 

 about a quart of oil in twenty-four hours. The lamp burns beneath a small boiler which 

 connects with the tank, as illustrated in the above cut. By no possibility can the fumes of 

 the lamp enter the incubator or reach the eggs.
