constructed entirely of concrete. It is tliree feet deep, seven feet six 

 inches long on top and three feet six inches long on bottom. It is 

 eighteen inches wide on the bottom and thirty at the top. The end 

 next the passageway is perpendicular, requiring the animals to plunge 

 in; the other end is sloping with creases in the cement forming little 

 steps to enable sheep and hogs to walk out. Adjacent to the vat and 

 separated from it by an eight-inch cement partition, is a dry chamber 

 five and-one half feet long, two and one-half feet deep, and eighteen 

 inches wide, for an attendant to stand in and hold or handle sheep, 

 as the vat is used for both sheep and hog dipping. One end of this 

 chamber is raised nearly a foot to enable the attendant to assist sheep 

 up the incline. The cement floor around the vat is so graded that the 

 drippings are returned to it. This illustration shows, also, the drain 

 pipe leading to an underdrain with the valve in the dry chamber below 

 the floor level of this part. This vat was easily constructed, inexpen- 

 sive, durable, and is entirely satisfactory.
