DIGGING CELLARS AND FOUNDATION TRENCHES No farmer wants to put an expensive barn or house on a poorfoundation, and it would be hard to find a greater benefit to afarm than a good cellar. The proper location for a building is on aknoll, and the rock often comes nearer to the surface on the knollsthan it does in the hollows. This makes both good foundations andgood cellars possible with the help of dynamite. With sharp drills, acouple of sledges, 40 per cent, dynamite, fuse and No. 6 blastingcaps, a cellar can be excavated, and the rock squared up for founda-tion piers or walls, in a short time and at little expense. In fact, ittakes little, if any, more blasting to put a house or barn on rock thanit does to quarry elsewhere the necessary stone for cellar walls and 55. GETTING THE FARM IN SHAPE foundations. The rock blasted out can also be used for the wallsand piers. If it is not possible to locate the house and barns on rock, thenthe foundation trenches and cellar in the clay, gravel or shale canbe dug much more quickly and easily if the material is loosened upwith an occasional charge of 30 per cent, dynamite. The stone for cement construction of all kinds can be easilyblasted out in the proper size for the crusher with 40 per cent,dynamite. WELL SINKING Wells are frequently sunk through rock or ground which can-not be dug to advantage without the aid of explosives. In wellsinking, when rock is reached and the earth or sand above is prop-erly shored, a circle of four or five holes should be drilled abouthalf-way between the center and the sides of the well, pointing atan angle, that will bring them close together near the center whenthey are three or four feet deep. These holes should be loadedabou
