cattle a good plan is for each to contribute in proportion to the 

 number of cattle owned and use the fund for building a community 

 dipping plant. In designing or selecting a plan for a dipping plant 

 it is well to remember that the vat should be constructed so as to be 

 suitable for use in dipping for scab as well as for lice and other 

 parasites. 



Two styles of dipping plants are shown in the plans (figs. 10 and 

 11). Either of these is suitable for dipping cattle or horses for any 

 purpose. The chutes, draining pens, etc., shown in one set of plans 

 may be substituted if desired for those shown in the other. 



If a dip is to be used which requires cooking and settling, such as 

 homemade lime-sulphur, commonly employed in the treatment of 

 scab, it is necessary to provide boiling and settling tanks (fig. 12). 



SELECTING A LOCATION. 



In selecting a location for a dipping plant the fact that animals 

 work better up grade should be considered, and the corrals and run- 

 ning chute should slope up to the entrance end of the vat. The vat 

 should be on level ground, preferably extending north and south

with the entrance at the south and the exit at the north, as it has 

 been observed that animals work better when not facing the sun. 

 A considerable quantity of water is used in dipping, so the dipping 

 plant should be located close to an adequate supply. The vat, how- 

 ever, should not be located on low, marshy land or where flood waters 

 overflow. 



CORRALS AND CHUTES. 



The receiving corrals, into which the animals are driven prepara- 

 tory to dipping, as well as the holding corrals, into which they go 

 from the draining pens, should each be large enough to hold the 

 largest herd to be dipped. They should be constructed so that there 

 may be the least possible number of corners in which the cattle may 

 become crowded and injured. 



The proper design and construction of the chutes is important, 

 because improperly constructed chutes add greatly to the difficulty
