54 a EXPERIMENT STATION. [Jan. 



For a period of about a year and a half prior to July, 1917, 

 Dr. J. B. Lentz was in charge of the blood-test work. On 

 the above date he was granted an indefinite leave of absence 

 to enable him to enlist in the national service. After a time 

 spent in several different military camps in this country he 

 was sent overseas for service in veterinary lines of work, 

 with the rank of captain. At the present writing he is still 

 in service overseas. 



In order to continue the testing, Dr. C. T. Buchholz was 

 secured to begin work on July 1, 1917. He carried on the 

 work very suc^cessfully for a period of about two and one-half 

 months, when he resigned to accept a position as a veterinary 

 practitioner in his home State of Pennsylvania. 



After a brief suspension of the work following the retirement 

 of Dr. Buchholz, it was resumed in October, 1917, by Dr. G. 

 E. Gage, associate professor of animal pathology. It was 

 carried along by him until Feb. 1, 1918, when he was given an 

 indefinite leave of absence to enable him to enter the military 

 service of the country. As a member of the Yale Medical 

 Unit he has been overseas for several months in charge of 

 certain lines of pathological and serological work connected 

 with the service. n 



With the retirement of Dr. Gage it again became necessary 

 to suspend the testing of birds. It was hoped that the sus- 

 pension would be only temporary, contingent upon securing 

 the services of a suitably trained pathologist and bacteriologist 

 to enable us to again resume it. After prolonged search it 

 was found impossible to find a pathologist and bacteriologist 

 outside the service who was willing to vacate the position he 

 then held to accept a temporary appointment in the veterinary 

 department to engage in this control work. On this account 

 we have not been able to do the testing that we had hoped to 

 do prior to the coming of the present hatching season. 



When the work was suspended in February of 1918, a circu- 

 lar letter was addressed to every poultryman and applicant 

 for the test who had had birds tested, advising that there 

 would probably be a suspension of the work, and suggesting 

 the advisability of his keeping his tested stock for the hatching 

 reason of 1919. Where this has been done the poultrymen
