DISEASES OF SWINE. 



INTRODUCTION. 



The most erroneous opinions prevailed for a lono-

 has proved these fancies to be most incorrect, and it is 

 well known that pigs always prefer a clear sty and 

 clean litter to those that are dirty ; and it is an equally 

 well-ascertained fact, that they never thrive when 

 these important points are neglected. 



If it is possible, swine-sties should be constructed 

 in localities through which a running stream passes, 

 and their sleeping-houses on a sloping bank, so that 

 they may be dry and comfortable for the animals,

 the enclosure appropriated to them. Those who keep 

 a number of pigs should have separate sties for the 

 young and the old, as well as for the accommodation 

 of those which are in pig ; and where they should be
