The Plant. 



The plant is modern in all its appointments. It is fireproof, sani- 

 tary, and electric lighted. It is equipped with the most up-to-date 

 fixtures, machinery and laboratory apparatus that money could buy, 

 including cold storage facilities. The sewerage system is complete. 

 The plant fronts 100 feet on Clinton Street, and runs back 175 feet to 

 the N., C. & St. L. Ry. It is within two squares of the Nashville 

 Union Stock Yards, where most of the hog supply is obtained. The 

 pens and hog sheds are substantially constructed with concrete floors 

 throughout. The plant consists of a modern brick building 14x100 

 feet. This building contains bedroom for attendants, office, hypering 

 room 14x17 feet, virus laboratory 10x14 feet, bleeding room 14x20

PART III— PROTECTIVE VACCINATION. 



Origin of the Dorset-Niles Method. 



Dr. M. Dorset, together with Dr. W. B. Niles — who conducted most 

 of the field experiments — perfected the Dorset-Niles Anti-Hog-Cholera 

 Serum until now it is well out of the experimental stage. We have no 

 hesitancy in assuring swine owners that this serum when properly 

 made and intelligently administered will protect healthy hogs against 

 cholera under all conditions and circumstances. 



To Dr. Dorset, a native Tennessean, belongs the honor and credit 

 of discovering anti-hog-cholera serum. He was born and raised near 

 Columbia, in Maury County, and is now Chief of Bichemic Division of 

 the U. S. Bureau of Animal Industry. Many eminent scientists claim 

 that in the discovery of this method of combating hog cholera Drs. 

 Dorset and Xiles have given to the world the greatest discovery 

 known to the science of veterinary medicine. We, as Tennesseans, 

 should at this time he especially appreciative of this great achievement 

 of Dr. Dorset, who has reflected credit and honor upon Tennessee 

 and the nation at large. 



Although only four years have elapsed since the Dorset-Niles Anti- 



Hbg-Cholera Serum wax perfected there are at this time twenty-three 



States engaged in making the product. These State* plants cost $299,-
