added to the interest of the experiment, but introduced an 

 unnecessary risk. Thus young turkeys hatching from a batch 

 of eggs incubated by an old turkey hen were left in her care. 

 Other young turkeys were 

 kept near the hennery and 

 then placed with the brood, 

 mothered by the old turkey. 

 Furthermore, the man in 

 attendance, having no great 

 faith in new-fangled no- 

 tions, and none whatever 

 in professors, was less in- 

 terested in the brooder 

 turkeys, and some loss re- 

 sulted from crowding and 

 other causes. Examination 

 of the organs of those 

 dying showed no evidence 

 of blackliead. 



The yards for the various 

 groups of turkeys were 

 built on grassed-over slop- 

 ing ground with more or 

 less shade furnished by 

 small white pines. The 

 general arrangement of the 

 vards is shown in the ac- 

 companying plan. 



On May 15, at the time 

 of our first visit to the 

 farm, we found the old 

 stock turkeys occupying an 



old enclosure designated as yard A. It was decided to fence 

 in some new land on slightly higher ground to the south, 

 making yards B and C, the former for the two lots of young 

 tiukeys already hatched and in the care of common hens, 

 and the latter for future incubator and brooder raised tm-keys 

 which would be free from any contact with hens or older 

 tiu-keys. These yards were about 85 feet square and cost
