148 DEPARTMENT OF AGRICULTURE. [Pub. Doc. 



ACKNOWLEDGMENTS. 



The thanks of the Bureau are extended to Dr. Charles E. 

 Marshall, Professor J. C. McNutt and J. A. Gamble, judges of 

 the clean milking and grade heifer contests, and dairy products 

 show, respectively, for services gratuitously rendered. 



DAIRY EXHIBITS. 



The results of the 1917 clean milking contest were displayed 

 at the Public Winter Meeting of the State Board of Agriculture 

 at Worcester, January 8, 9 and 10, 1918. An interesting demon-

 preparations were made for exhibits in shows to be held during 

 the autumn months, which were finally canceled on account of 

 the outbreak of influenza. Mr. Lombard, however, took an 

 exhibit to Portland, Maine, where he had charge of the Massa- 

 chusetts exhibits at the Maine Fruit and Farm Products Show. 



LECTURES. 



The general agent delivered sixteen lectures on dairying sub- 

 jects during the year. He also procured the services of Dr. 

 E. V. McCollum of the Johns Hopkins University, who deliv- 

 ered two lectures, one at Worcester and the other in Boston, 

 both of which were well attended, especially by interested 

 workers, which resulted in wide dissemination of Dr. McCol- 

 lum's discoveries concerning the food value of milk. 



INVESTIGATIONS. 



The general agent visited both the Johns Hopkins University 

 and the United States Department of Agriculture in his in- 

 vestigations into the food value of milk, and the Bureau made a 

 two days' trip through the milk shipping sections of Maine, vis- 

 iting the following places: Wiscasset, Richmond, Unity, Troy, 

 Plymouth, East Newport, Cornish, Barton, vEtna, Pittsfield 

 and Auburn; also the Ayredale farm at Bangor and the Uni- 

 versity of Maine at Orono. The principal object of the trip 

 was for the purpose of studying the methods and shipping sta- 

 tions of the Turner Center Dairying Association. These sta-
