H.J. Hall
All-Weather Stock Tank
A well insulated concrete tank has been in use on a Boone county farm for a full year with no trace of ice on the water even in temperature 5 degrees below zero. It is equipped with automatic float valve and trickle overflow pipe, the latter to be used only in freezing weather. The tank gets its water supply by gravity from a large pond. With such a tank any one of the thousands of good farm ponds in Missouri may be made a dependable year-around means of having water before livestock at all times. The cost per year of service is low.
