ly moved to other locations. Concrete vats are practically perma- 

 nent as to location. 



A vat should be of the following dimensions: 



Top length ....10 ft. 8 in. Top width 2 ft. 4 in. 



Bottom length 4 ft. 8 in Bottom width ..1 ft. 6 in. 



Depth 4 ft. 4 in. 



There should be an incline on both the inlet and outlet ends. The 

 dripping pen should be about 5 ft. square and the floor so arranged 

 that the drip from the animals will drain back into tlie vat. 



PROPER DRAINAGE ESSENTIAL 



The location of hog yards and lots so as to insure proper drain- 

 age is frequently overlooked. On many farms the hog lot is located

on ground that is low, boggy or swampy and is apparently of no 

 value for any other purpose. The selection of such lots is a serious 

 mistake and is frequently responsible for the failure to produce hogs 

 at a profit on that farm. Hog lots should be high and dry and so lo- 

 cated as to insure good drainage. The old hog wallow serves no good 

 purpose but does provide a ready means for the propagation of a 

 variety of infective agents and serves to promote the maintenance of 

 animal parasites on the premises. Low areas should be overcome by 

 grading, thus preventing the accumulation of stagnant water. Pas- 

 turing is the preferable way of maintaining hogs from the sanitary 

 viewpoint.
