LIVESTOCK PARASITOLOGY — SCHWARTZ 357 



These are, indeed, difficult questions to answer today, in a world 

 that is already beset by more perplexities than it can find time to re- 

 solve. The livestock parasitologist adds little or nothing to the 

 world's perplexities, however, but like other agricultural scientists, 

 offers much that can help to resolve them. The livestock parasitologist 

 is a conservationist, being essentially concerned with maintaining and 

 increasing the supply of human food which, in the final analysis, is the 

 greatest of our natural resources.
