Photograph of Mr. C. F. Cornelius, member of the board of supervisors of the Little River Soil Conservation District, retired a few years back as a construction engineer for the Stanolind Oil Company, but he still likes to build. He constructed this fine water tank at the cost of only $14.26 in materials and labor. He gets water from a running spring. Lifting water 8 feet in 1 ¼ inch pipe using a 2 ½ horsepower motor (gasoline). The tank is of concrete, 8 ½ feet in diameter and 22 ½ inches deep. It holds 800 gallons of water. The cost is less than 2 cents a gallon to build the tank. It took 296 common bricks, and 4 sacks of cement with sand and gravel coming from a branch on the farm. 4-point barbed wire is placed around the top of the tank for reinforcement. It can pump the tank full in 10 minutes. This took only half a day to build. It is located where Mr. Cornelius can have water for two pastures. Fresh water pays off with better wattle.
