PLAN OF OPERATIONS 



Reference to Bulletin No. 23^ shows that the procedures of this year have been 

 a continuation of those of last season. The machinery of operation has been more 

 effective. The educational part of the program has been successful, a tremendous 

 amount of interest has been stimulated, and poultrjTnen have responded to what- 

 ever supervision the department has been able to give. This has been indicated 

 by their replies to questionnaires sent and by the cordial spirit with which they 

 have met the representatives from this department. Staff members have requested 

 and obtained data concerning the hatchability of eggs laid by hens known to be 

 free from bacillary white diarrhoea, and the livability of chicks hatched from such 

 eggs. The fact that the program is one applying science to practice has been kept 

 constantly in mind, and in carrying out this program poultrymen have been of 

 greater help than ever before. 



The testing plans which follow have been continued during the year. Poultry- 

 men have co-operated as requested by adopting one of the three testing plans 

 outlined, and there has been a general willingness on the part of them aU to 

 observe the precautions listed under "Control Measures."
