Successful farming : a ready reference on all phases of agriculture for farmers of the United States and Canada . n-crete is most dura-ble if allowed to dryslowly.

It is safest to provide a meansof draining the water off during cold periods. The accompanying sketchshows the foundation, drainage pipe, forms and reinforcement necessaryin the construction of a concrete water tank. Both wooden and metal forms are used. The latter are preferable inthe construction of silos and round water tanks. Metal forms, when usedrepeatedly, are cheaper than wooden ones. They leave a smoother concretesurface than wooden forms. The latter should be soaped or greased onthe surface next to the concrete to prevent the material sticking to theforms. Wooden forms should also be sprinkled with water before beingfilled with concrete, lest they absorb water from the mixture too rapidly. 1 Courtesy of The Pennsylvania Farmer, How to Construct a Concrete Water 710 SUCCESSFUL FARMING The concrete materials should be thoroughly mixed and enough waterused so that the mixture Avill flow slowly. The smaller the forms intowhich it is placed, the more liquid it should be. Where much work is tobe done, mechanical mixers facilitate the work and do it more thoroughlythan can be done by hand. In the absence of a mechanical mixer, astrong, tight board platform, about 8 by 10 feet in dimension, is convenienton which to do the mixing. A square-pointed shovel, a rake and two ormore hoes may be advantageously used in mixing the material. If run-ning water is not available, water in barrels or a tank should be convenientto the mixing board. The cement usually comes in bags of 100 poundseach, equal to one cubic foot. Bottomless boxes for measuring sand andgravel are most convenient. They should be construc
