Notes. — Both dry and wet mash were of the same composition and identical with 

 the ration given above. 



The pullets on the dry mash were allowed to eat from a hopper ad. lib., while the 

 wet mash was fed once a day and as much as the birds would eat up clean. 



The dry mash in this instance produced more eggs per bird, but the cost per dozen 

 was practically the same. 



incubators. 



All the incubators were run in a small cellar. This cellar kept a reasonably con- 

 stant temperature throughout the season. The average highest temperature of the 

 cellar in the morning for any machine's period was 62-4°F., and the afternoon was 

 <33-7°F. The temperatures were kept from the 15th March to the end of May; the 

 highest temperature recorded was 70-6°F., and the lowest was 54:-6°F., but this range 

 was spread over a period of over seventy days while the temperature outside was 

 gradually going higher. The following chart will give an idea of the average tempera- 

 ture of the room and machines during the hatching season, also the very highest and 

 lowest temperatures that the machines or room attained during all the settings. 



The highest temperature recorded may not have occurred in the same hatch as 

 the lowest, but it is the extreme range of the season.
