. Concrete silos; a booklet of practical information for the farmer and the rural contractor. Concrete; Silage. 98 CONCRETE SILOS The Perfect Silo, built by the Perfect Reinforced Silo & Cistern Block Co., of Delaware, Ohio, has met with great favor amongst Ohio farmers and a large number have been put up in Delaware and gilo adjacent counties. Some of these silos have been built by the owners with block purchased from the above company. This system differs from all others in the dimensions of the blocks and the method of reinforcing. The blocks are 24 inches long, 12 inches high, and 4 inches thick. Each block is reinforced with two iron bands running lengthwise 6 inches apart. Each rod is looped and turned 6 inches from each end. These loops are spaced so as to correspond with ^-inch round vertical holes which are formed in the block. When the blocks are laid in the wall these vertical openings are filled with cement grout and steel dowel pins are passed through this soft material and inserted about half way in the block below. The rods should be of such length that they will reach up about half way in the blocks above. The blocks have a groove Yi inch deep in the top edge which provides space for a larger mortar bed and also for the heavy horizontal rods which span the contin- uous door openings at intervals of 2 feet. These rods are firmly fastened to the vertical dowel pins. The dowels next to the door openings are made of heavy pipe in 4-foot sections firmly screwed together. This system is shown on page Hurst Silos built on famous Crab Tree Farm, Lake Bluff, Illinois. Built after fire had de- stroyed everything but concrete milk house.
