be fertile in Maine but proves to be unfertile after transpor- 

 tation to the purchaser's premises. In one case, where suit 

 was brought by a buyer on the Pacific coast against a breeder 

 on the Atlantic coast, the latter set up the plea that the trans- 

 continental journey had destroyed the fertility of a young 

 bull. Many sympathetic breeders were brought into court 

 who swore that railway journeys frequently render fertile 

 bulls sterile. The jury failed to agree. Unquestionably the 

 bull was absolutely sterile on the day of the sale and had al- 

 ways been sterile. The statutes of the state made the sale 

 of the bull for breeding purposes a warranty of fertility. 

 Had there been an explicit written warranty of fertility to 

 the buyer, whose address was known to the seller, no such 

 claptrap evidence could have had weight. 



In the present state of the health of cattle, the purchaser 

 should also require a warranty against tuberculosis to the 

 extent that the animal shall pass a satisfactory tuberculin 

 test after it has reached its destination. A tuberculin test 

 upon the breeder's premises is his test for his use. He must 

 make that now for interstate shipment. A test at destina- 

 tion is the purchaser's test for his security. The breeder is 

 entitled to satisfactory assurance that infection in transit 

 or at destination will not occur and that the tuberculin test 

 will be fair. 



B. The Equipment for Cattle Breeding and Dairying. 



Proper equipment is a fundamental necessity in the grow- 

 ing of healthy cattle or other animals. The plans should be 

 such as to afford the highest possible general and sexual 

 health of the animals. There is an irrevocable law that, the 

 greater the mass of animals and the more intimately they 

 are brought into contact without special hygienic provisions, 

 the greater the ravages of disease. If it is desired to establish 

 a large herd, special provision needs to be made against the 

 dangers of its largeness. Aside from the highly contagious 

 maladies like foot-and-mouth disease, which the state regu- 

 lates, contagious or infectious diseases are chiefly spread 

 through the eating of contaminated food or through sex con-
