of the late-molting hens matured early and during a period of seven 

 months show considerable increase both in number of eggs and in 

 value over the original flock. This work is being continued for 

 verification of results. 



SOUTHWESTERN POULTRY INVESTIGATIONS. 



Experimental breeding and feeding investigations with Single 

 Comb White Leghorns and Single Comb Rhode Island Reds are 

 being carried on at Glendale, Ariz. The stock was obtained from 

 the Beltsville farm and the trap-nesting and pedigree work is being 

 conducted along similar lines. Considerable information on the 

 hatching, brooding, rearing, housing, and feeding of poultry under 

 conditions in this Southwest section has already been obtained. 



Bronze-turkey breeding stock has recently been purchased on the 

 Pacific coast and is now at Glendale, to be used in feeding and breed- 

 ing investigations. The natural conditions and environment seem 

 favorable for turkey production. 



PIGEON AND SQUAB INVESTIGATIONS. 



The loft of racing homing pigeons, having served its purpose, 

 has been materiall}^ reduced, only a good breeding nucleus being 

 maintained. The data on this work are available for publication. 



The squab-breeding pigeons have increased in number and the 

 younger stock in the Red and Yellow Carneaux will replace many 

 of the older birds. A few pairs each of White Kings and White 

 Runts have been purchased to obtain new blood. Data on feed cost 

 of squab production, breed comparison in prolificacy, and rate of 

 growth and weight- are being accumulated. 



DAIRY DIVISION. 



Tlie work of the Dairy Division, under Dr. C. W. Larson, chief, 

 progressed in line wnth the present policy of discontinuing extension 

 work and devoting more time to research problems. In the course of 

 this reorganization the dairy extension section and the dairy manu- 

 facturing section were merged to form the dairy introduction section 

 January 1, 1922. Under this arrangement fewer men are needed to 

 do the introduction work, and this has made it possible to enlarge 

 the corps of scientific workers on research problems. 



DAIRY INTRODUCTION. 



The principal work of the new dairy introduction section is to 

 introduce, in cooperation with or through State extension forces, 

 new or improved methods, practices, and ideas. Direct and sub- 

 stantial assistance is furnished until the projects are properly estab- 

 lished, then the assistance is withdrawn and the work is left to the 

 direction of State or other local agencies. Regular extension proj- 

 ects in both production and manufacturing are being discontinued. 

 Much of the work formerly done by the Dairy Division has been 

 continued by the States. The activities of the introduction special- 

 ists are centered principally about the following subjects: Cow- 

 testing associations, bull associations, utilization of dairy products,
