DIPPING VATS 



In those sections of the United States where there are a large num- 

 ber of horses to be dipped cattle-dipping vats usually are available. 

 and they can be utilized for dipping horses. Plans of cattle-dipping 

 vats suitable for dipping horses are given in Farmers" Bulletins 1 17 

 and 1057. 



The so-called cage vats are sometimes used for dipping ho:- - 

 In these vats the animal is placed in a movable cage and lowered into 

 the bath by means of a windlass or other mechanical apparatus. 

 The operations are much slower than in the longitudinal vat. 



Portable, galvaui zed-metal vats may be purchased, and they are 

 suitable for dipping a small number of animals. After diggi: _ 

 trench and setting the vat so that the top is flush with the surface oi 

 the ground, a chute and slid- sh old be provided as a means of 



g -::ing the horses into the vat.
