When a ditch is blasted there is no outlay for expensive equip-ment, because the only machinery necessary is an iron bar, pointedat one end. In hard, dry ground, a sledge or maul is needed todrive the bar down to the necessary depth. There is no delay andexpense getting machinery into place through swamps and even a team is needed when ditches are dug with dynamite,for one or two men can easily carry sufficient dynamite to dig aditch four or five hundred feet long, four or five feet wide, andthree or four feet deep. 46. GETTING THE FARM IN SHAPE When ditches are dug with dynamite the material taken fromthe ditch is practically all thrown out by the blast, and little or noshoveling is necessary. This material is not heaped up along thesides of the ditch, where it would occupy land that should be raisingcrops, and would prevent free drainage into the ditch, but is spreadevenly over the ground for a considerable distance on each side ofthe ditch. Ditches can be dug with dynamite at any time on a coupleof hours notice, as dealers who handle explosives can be found inalmost every locality. In wet weather, especially after heavy rainfalls, when it may be necessary to cut ditches and channels in ahurry, this method is invaluable. It is just as easy to dig a curved ditch with dynamite as it isto dig a straight one, because the center of the ditch follows theline of holes in which the dynamite is loaded.
