spreading trees affords the greatest comfort to hogs that are confined 
in large inclosures and pastures with either fixed or portable houses. 
The ground occupied by the swine should slope away from the 
house so as to facilitate drainage. Hog houses should never be built 
at the base of a slope. 
Hog fences are a serious problem to the average swine raiser. 
Hogs get through fences with greater ease perhaps than does any 
other class of animals. A fence should be about 4 feet high and 
strongly constructed with, preferably, split redwood posts. The 
posts should be set 3 feet deep and 8 feet apart and have firmly 
spiked to them 1J by 12 inches by 16 feet planks, which are set

6 inches in the ground along the fence line. A plank, \\ by 12 inches, 
should also be set above the baseboard, and the joints should be 
broken to give rigidity to the fence. The heaviest and closest woven 
wire hog- fencing obtainable, 32 to 36 inches high, should be stretched 
tightly across and securely stapled to the plank and posts. The fence 
can be greatly strengthened if the lower part of the wire fencing is 
placed between the plank and posts rather than on the outside of 
the plank. The wire fencing should be lapped at least 3 inches down 
the back of the plank and surmounted with a strand or two of 
barbed wire. (Fig. 9.) 
Boar fences should be higher than 4 feet and very strong. A 
pedigreed Tamworth boar weighing 600 pounds has been known to
