 101 blood samples from pigs. Upon the basis of several years' testing work and 

 a required final qualifying test by the official laboratory, the college herd re- 

 ceived a Bang Abortion Disease-Free Accredited Herd certificate from the 

 Massachusetts Division of Live Stock Disease Control in November, 1936.

Consultation and Information Service. Along with its function as a 

 research unit of the College, the Field Station has continued to expand its service 

 as an information center. Commercial growers and amateur gardeners are 

 finding this service of increasing value as evidenced by more than 3,600 tele- 

 phone calls and 3,800 visitors seeking help during 1936. In addition, 807 came 

 to attend meetings of thirty garden clubs which were held at the Field Station. 

 The Boston Market Gardeners Association, the Boston Branch of the National 

 Gardeners Association, the National Shade Tree Conference, and the Massa- 

 chusetts Association of Greenkeepers, held well-attended meetings here in 

 which members of the Field Station staff participated. 



Paul W. Dempsey was appointed to relieve the research men of the burden 

 of some of this growing activity but has only been able to take care of the 

 increase. At the request of various organizations he has given 124 talks on 

 the work of the Field Station and on general horticultural subjects during the 

 year. 



The ornamental display and test gardens attracted 3,500 visitors from June 

 1 to September 1. Increasing numbers of both commercial and amateur gar- 

 deners are visiting these gardens several times during the season to observe the 

 behavior of new introductions as compared with some of the older standard 

 varieties. 



Field Day. The Eighteenth Annual Field Day was held on August 5 with 

 an attendance of 1,200. The number of vegetable contests held at this time 

 is gradually being increased with the hope of making them an important part 

 of the Field Day program. The following contests were held this year: Celery, 

 Bunched Carrot, Pepper, Trellis Tomato, and Bunched Beet. Next year 

 Summer Squash will be added. The quality of the vegetables exhibited at 

 these contests is second to none.
