HATCHING AND BEABING. 45 



At both of these places a large room is devoted to the 

 incubators. 



There are various machines now upon the English 

 market which from personal experience I can recom- 

 mend with the greatest confidence. The first position, 

 of course, must be given to the " Hearson," made 

 by Messrs. C. Hearson and Co., 235, Eegent Street, 

 London, W.C. This is a wonderfully reliable machine, 

 with an excellent regulator, and it is scarcely neces- 

 sary to do more than mention it, because the 

 incubator has found its way into all parts of the 

 world. It is worked by means of a lamp or gas, and 

 is fitted with a tank, the regulator being a small 

 capsule whose contents expand greatly when the 

 temperatm'e rises above 104 degrees. The power thus 

 obtained is used for raising a cap and allowing the 

 surplus heat to escape. The machine is fitted with a 

 capital form of egg drawer, and excellent arrange- 

 ments are made for the supply of fresh air and 

 moisture. 



Another machine, also fitted with a tank, is the 

 " Monarch," made by Mr. W. Calway, of Sharpness, 

 Gloucester. This is the invention of an American, 

 and in the States it has been known for many years. 

 It is a well-made machine, and is produced in 

 various sizes, and stands upon legs supplied with 

 it. So far as we have gone it has worked fairly 

 weU. In this case regulation is obtained by the 

 expansion and contraction of the water within the 

 tank itself, which is made to act upon a flame guard, 

 increasing or decreasing the light as required. The 

 third machine is known as the " Premier," made by
