How do your samples stack up against the ones taken by your Great Grandfather?
Rickard, 1903: “No ground that can be mined in the ordinary way, that is, by drilling holes and charging them with an explosive, is too tough for a moil struck by a double-hand hammer, when swung by a good man.”
Modern Sampling: Attempting to Replace Labor with Air Tools
“In one case, which came under my notice, it took six men (three of whom moiled while the other three held the boxes to receive the samples) the whole of one shift to take three samples across a vein 12 ft. in cross-sections, and in accomplishing this they dulled 35 moils. That was good, honest sampling.”
