barrier on one side of the passage from the alley to the 

 vat. The other side has protection that is temporary and 

 movable. The dipping vat comes up against the side of 

 the platform and extends outward from the end of the hog 

 house. It is on a level with the platform and also of the 

 dripping pens at the opposite end. The vat is 9 feet long 

 on the top, 6 feet long on the bottom, 3 feet 8 inches deep, 

 2 feet wide at the top and I foot at the bottom. These are

 boiler in the hog house. The eaves of the hog house sup- 

 ply the vat with more or less water all the time, and this 

 is used in preparing food for the swine, but the vat is

 after all things have been made ready for the work. 



For a small flock a good-sized tub may be used or what 

 is more convenient, a small dipping vat such as may now be
