THE MILK MACHINE 327 
I should never feel easy about my swine until I 
had two houses for them, besides the brood-house 
for the sows. I therefore gave the order to Nel- 
son to build another swine-house as soon as 
spring opened. My plan was, and I carried it 
out, to move all the colonies every three months, 
and to have the vacant house thoroughly cleaned, 
sprayed with a powerful germicide, and white- 
washed. The runs were to be turned over, when 
the weather would permit, and the ground sown 
to oats or rye. 
The new house was finished in June, and the 
pigs were moved into it on July 1st with a lease 
of three months. My mind has been easy on the 
question of the health of my hogs ever since; 
and with reason, for there has been no epizodétic 
or other serious form of disease in my piggery, 
in spite of the fact that there are often more than 
1200 pigs of all degrees crowded into this five-acre 
lot. The two pig-houses and the brood-house, with 
their runs, cover the whole of the lot, except the 
broad street of sixty feet just inside my high 
quarantine fence, which encloses the whole of it.
