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,
