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 epizootic 

 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.
