 the situation is essentially the same. Torrance l 

 reports similar conditions in Canada. In the 

 Southern and central states a much smaller pro- 

 portion of herds become infected through the 

 agency of pork trimmings from carcasses that 

 contain hog cholera virus, but even in these sec- 

 tions there is ample evidence that the first infec- 

 tion in many outbreaks takes origin in this man- 

 ner. Once established in territory that supports 

 a dense swine population, the .disease spreads 

 rapidly through many other agencies.

 killing and marketing all animals that remain ap-

Disregarding, for the moment, legal and sani-

 These occur principally in herds of feeders about
