Project 3. "Summer forage crops." 



Professor Lindsey. 



Work the past season was confined to the growing of corn 

 and soy beans, alone and in combination, at different planting 

 rates, and by different planting methods. The past history 

 of the land used in the experiment, however, was such as to 

 render impossible the drawing of definite deductions from this 

 work. 



Project 4. "Record of the station herd." 



Professor Lindsey. 



This is a continuing project in which accurate record is 

 kept of the food consumed by individual cows, the amount of 

 milk produced, the determination of milk solids and milk fat, 

 and estimation of the food costs. As records accumulate this 

 work is of increasing value.

Project 1. "Broodiness in poultry." 



Professor Goodale. 



The line of attack includes the following: (1) Elimination of 

 broodiness from the high lines through suitably tested matings. 

 The percentage of broodiness has now been reduced to about 

 forty. One family of eleven daughters has been produced ap- 

 parently entirely free from broodiness, and another and highly 

 inbred family shows but one broody member out of fourteen 

 daughters. (2) Production of intensely broody race. (3) 

 Investigation of the effect of crossing. This work is supple- 

 mented by physiological studies of the dift'erent organs asso- 

 ciated with the phenomenon of broodiness.
