"Good containers or places to put salt blocks are hard to find," writes Quentin Johnson of Vernal, Utah. To solve the problem he recycled his mineral-lick tubs and used them for salt block feeders.

To allow water to drain out, Mr. Johnson drills holes in the bottom of the tub. Next he fills the tubs two-thirds full of medium sized rocks on top of which he places his salt blocks. The rocks keep the moisture away from the salt blocks. They also make the tub heavy enough that cattle can't tip it over or move it around.
