When a large animal strikes the fluid the splash will fly as high as 6 feet, and the spray will scatter widely.

When a large animal strikes the fluid the splash will fly as high as 6 feet, and the spray will scatter widely. The accompanying detailed sketches illustrate two vats equipped with splashboards wdiich have been used veiy successfully for a num- ber of years in Texas. The first sketch (fig. 4) is a cross section of the vat consti-ucted by Mr. J. J. Welder, Victoria County, Tex. A ground plan of the entrance is illustrated in figure 5. Mr. Welder's vat is a rather large one, having a surface level of the dip 5 feet wide but with an entrance chute to the vat of only 3 feet and 9 inches. The splash- boards are 2 feet wide and 20 feet long, ex- tending from the termi- nation of the entrance chute. In the case of this dipping vat the ani- mal is confined to the middle of the vat and entirel}^ awa}^ from the splashboards by the nar- row entrance chute. Another similar vat is illustrated in figure 6. This vat was con- structed by Mr. A. P. Borden on the Pierce K, anch, Wharton County, Tex. The splashboards are 1 foot wide and ex- tend the full length of the vat, and can be used, if necessary, as a walk in assisting cattle in trouble. The ends of the splashboards next to the entrance are rounded off in the case of this vat; but the entrance slides, as illus- trated in the ground plan of the Welder vat (fig. 5), and the height of the splashboards above the dip level, have in the actual treating of hundreds of cattle prevented any difficulty of catcliuig or collidmg of the animals with the splashboards, and were used on a number of vats in Texas most successfully during the years 1907 to 1909.
