SUGGESTIONS AS TO CONSTRUCTION AND MATERIALS. 



This vat may be built of wood, brick, concrete, or galvanized iron, 

 and should be at the bottom 16 to 18 inches wide, inside measurement, 

 34 to 36 inches wide at the water line, and may be continued to the top 

 at the same width; 36 inches width is desirable where cattle with wide 

 horns are to be dipped. When built on the above lines, with a total 

 depth of 7i feet, the splash boards may be dispensed with.

PIG. 11. Showing tank with spring trap, as seen from above. 



FIG. 12. Vertical section of swimming tank, showing trap down. 



Where an automatic drop is used for dropping cattle into the dip, 

 the dipping tank must be wide enough to permit the trap to drop 

 inside to a sufficient depth to throw the cattle into the swim.
