coming heated tc the necessary temperature by means of a special 

 arrangement before reaching the main compartment. 



As soon as the chickens are hatched they are passed into another 

 compartment where they are kept for 20 hours without food, 

 when they are removed to the brooder. 



This brooder is divided into two compartments, both kept at 

 equal temperature by means of an electric heat radiator, one for 

 use at night, the other for occupation during the day. There is 

 a special contrivance by means of which the temperature can be 

 gradually lowered as the birds grow stronger, until finally the 

 artificial heat can be dispensed with altogether. This hatching 

 arrangement is, of course, merely dependent upon electricity as 

 a source of heat, but one experimenter has gone a step farther. 



Mr. T. Thorne Baker has recently completed an experiment of 

 bringing up young fowls in an electrified atmosphere. The 

 chickens were reared under exactly similar conditions, fed in the 

 same manner, brought up by the same foster mother on the same 

 plot of ground. Half the young birds were placed on a plot which 

 was electrified by means of a high tension discharge apparatus, 

 and from the commencement of their electrified treatment shewed 

 a much more kindly and contented disposition than their un- 

 electrified neighbours, and finally when the two lots were weighed 

 shewed an average increase of 38.5 per cent, in weight.
