When the wall is seasoned and forms removed, lay the sills on the wall, the dimensions of the intended structure leveled and bedded in mortar. Where a girder is required, double two to four thicknesses of 2" plank, indimention, to the weight to be carried; chisel a bearing in the wall so the top of the girder will be level with the top of the sill, put posts of 6'x6' or heavier, under the girder, 6' to 8' apart for ample support of the building.
