Development. — During the year the equipment of the poultry 

 department has been materially enlarged to meet the needs of the 

 increased number of students and the necessity for investigation 

 of many poultry problems. The main poultry building has been 

 completed. Several additional varieties of fowls and ducks have 

 been added to the stock, which now numbers approximately 500 fowls 

 and 30 ducks, representing 17 varieties. 



On the whole, the poultry department, while not as large and as 

 well' equipped as it should be in order to accomplish the best results, 

 is -nevertheless on an effective working basis.
