preferable. It is dangerous, however, to withhold salt from 

 hogs for a long time and then give them a large amount. 

 If a supply of some such mixture as that described is kept 

 constantly before the pigs, there is no danger that they will 

 take too much. Sods make a very fair substitute for char- 

 coal. A wagon-load or two of sods placed conveniently 

 near the piggery so that the feeder can throw one or two 

 into each pen occasionally, will be found very beneficial 

 during the winter, Pigs that are outdoors in summer and 

 have access to earth and vegetable matter, have little need 

 of other correctives. The term corrective is used for want 

 of a better, but such substances as those described appear 

 to correct or prevent derangement of the digestive organs 

 and play a very important part in pig feeding.

Lice are a common source of loss to the hog raiser, and 

 are especially injurious to young pigs. They are most 

 commonly found around the ears, inside the legs, and in 

 the folds of the skin about the jowl, sides, and flanks. A 

 two per cent solution of creolin (2 parts creolin to 100 parts 

 water) makes a very good wash for lice. Most of the 

 standard sheep dips are also effective, but treatment of any 

 kind must be repeated several times to eradicate these pestSi 

 Coal oil is very effective, but is liable to blister, or remove 

 the hair. A' very good wash can be made as follows: 

 Thoroughly mix 4 ounces of soft soap with -6 quarts of soft 

 water; then add 8 ounces of naphtha and mix again. This 

 wash makes a good insecticide, and is also beneficial to the 

 skin. Thorough cleaning of the pens, and spraying them 

 with a good disinfectant, such as the creolin solution, will 

 be found helpful. Occasional whitewashing also tends to 

 keep vermin in check. 



Sanitation. 

 The hog is an extremely difficult animal to treat when 

 anything goes wrong with him, and, unless it is some very
