The offspring of 28 of the 34 selections had individual ranges 

 itf heading dates that were approximately the same as those of the 

 parents. The standard deviations from the mean heading dates 

 were of approximately the same size as those of the parents. These 

 facts, together with the fairly high coefficient of heredity and the 

 grain texture studies, indicate the possibility of producing early 

 races oi hard wheat which are suitable for the irrigated districts 

 of Arizona.

During the fall, several cockerels of breeds and varieties promi- 

 nent in Arizona were purchased for breeding purposes. These 

 cockerels are of known pedigree from high-producing strains, and 

 are to be used in founding high-laying strains from which males 

 can be secured to improve the flocks of Arizona. 



A number of vocational students enrolled for work in poultry, 

 which greatly increased the incubation and brooding activities. 

 Two large brooder houses were erected and equipped with oil- 

 burning brooder stoves. These houses were designed to accommo- 

 date five hundred to one thousand chicks each, but it was soon 

 found that they would handle these chicks for not to exceed four 

 weeks. 



An 1800-egg Mammoth incubator was also installed ; but the 

 results from it were not satisfactory, due to improper coal an<l 

 unsuitable location for operation. 



Owing to the very limited housing and rearing facilities for 

 developing chicks, it was necessary to dispose of almost all the 

 young stock. 



Considerable data were secured as to the advisability of an 

 intensive fattening period before marketing the early broilers and 

 the practicability under many conditions of caponizing the later 

 hatched cockerels. 



The different climatic and environmental conditions in this 

 part of the Southwest and the lack of information as to suitable 

 buildings, feed, etc., make experimental work along these lines 

 imperative. From the results of this season's work, the great im- 

 portance of having a house that can be adjusted to care for the
