Fig. 8. — Hogs are profitably pastured on winter oats. 
clean: further, the sticky mud often adheres to the bellies of the 
hogs, sometimes causing sores, particularly in the case of sows with 
suckling pigs. Watering troughs are used, but there is danger of 
the supply failing at a critical time ; further, it appears advisable for 
the animals to get into the water. 
During warm weather various pests, such as lice and mange, attack 
the hogs. A very simple remedy for prevention and cure is the use 
of crude oil as a disinfectant. This may be applied directly from 
a sprayer or by pouring on the backs of the animals, or it may be 
placed in a rubbing post. It is not uncommon to place the crude oil 
on the surface of the water in the wallows. \Yhen the pests become 
well established before being discovered, an emulsion of coal oil and 
soap solution is commonly used as a spray. 
Small scratches and the eyes and noses of pigs often become in- 
fected during the summer and if these infections are not cleansed 
they frequently cause considerable losses. Screw worms develop and 
bury deeply into the flesh. The use of crude oil as above indicated 
goes far toward preventing infection, but when screw worms have 
developed they must be removed or killed by the use of chloroform 
or the like. 
Very few buildings are necessary for successful hog production; 
a shade for summer, a slight protection from cold rains during 
" northers " in winter, and farrowing pens for sows and pigs, fully 
answer the requirements. 
Dairying. — This enterprise is receiving considerable attention, 
whole milk and cream being sold. The number of farms that can 
profitably sell whole milk is limited by the population of the towns 
supplied, so that this method of disposing of the dairy products can 
not be extended far beyond the present. There are a few very
