SANITATION IN THE HOG LOT 499 



or punctures, gixing- the surface a honeycomb appear- 

 ance. These Hce are often spoken of as occurring only 

 upon poor animals, but those that I have seen have been 

 equally numerous upon the fattest and best pigs. It 

 would be more correct to say that pigs upon which lice 

 haxe long been abundant are always poor, which would 

 make the presence of the lice the cause of the poor con- 

 dition of the animal, and not the poor condition of the
