If the blocks of wood and stone, or stone alone,are arranged as shown in the foregoing illustrations, withthe joints of the blocks abutted closely, properly filledwith hot fine sand and coal tar, the blocks will be heldperfectly secure and cannot settle or bulge. The cost of properly shaping the blocks to fit the girder T is no more than the cost of properly fittingblock
