Typical test loading to determine proper charges and placing of explosives for electrical firing. Note the variations in spacing between holes as well as in amount of explosives used. (See page 27.) such as boulders, ledges of rock, stumps, sod and roots of trees and brush. Under this method each charge is primed with an electric fuze. The work should proceed as follows: Collect tools, powder and supplies, including an electric blast- ing machine and necessary wires. Lay off ditch with stakes and line. Cut sod and roots, if any, at ditch sides, with plow, hay knife, spade or axe. Make holes in ground for test shot with bar or auger at proper ilistances and to right Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Atlas Powder Company.
