work was scrubbed and then washed with coi'rosive sublimate solu- 

 tion (1.1000) and finally whitewashed, and every care taken to 

 secure good drainage and ventilation. The result and effective- 

 ness of all this have been best demonstrated by the fact that every 

 animal brought to the place made a most marked improvement in 

 its general condition, while some of them even went so far as to 

 appear to get well. (Ernst.) 



The same thins; is shown in the case of some cattle at Mr. 

 French's farm at North Andover, where several animals were 

 slaughtered after testing with tuberculin ; a number of the 

 remaining animals that reacted to the tuberculin test were 

 turned out to pasture, and in the fall they were brought in 

 and retested by the State authorities, and they failed to 

 react, the recovery evidently having resulted from the open- 

 air life in pasture during the summer months. 



A similar incident is related by Professor Law. He says : — 



In 1877 I recognized the existence of tuberculosis in the Jersey 

 herd of Burden Bros, of Troy. The worst were slaughtered, but 

 some incipient cases in young animals were turned out in a pasture 

 by themselves, where they passed the summer in apparently robust 

 health, but they began to droop when returned to the barns in the 

 fall. (Paper by Prof. James Law, read at Peterborough, N. H., 

 December, 1892.) 



These are only a few of the examples showing the great 

 influence that the surroundings have on the health of the 

 animal body ; pages of statistics could be quoted and figures 

 given showing the same results, but that would only be an 

 unnecessary repetition, as the immense importance of good 

 sanitary and hygienic conditions is generally accepted by 

 every one. 



In suggesting improvement on the present method of 

 constructing dairy barns, cheapness of construction and con- 

 venience in handling, as well as the health of the stock, have 

 been borne in mind. Of course these ideas can be elab- 

 orated or modified according to the wealth of the owner and 

 the amount of money to be expended on the buildings ; but, 

 whether the cost is to be great or small, it is absolutely nec- 

 essary, if the health of the cattle is to be maintained, that 

 there should be pure air and good ventilation, as well as
