Regarding Labor Day Celebration. The Dictionary of Minerals and Mining defines double jack drilling as a "...historical method of drilling blastholes in rock by hammer
In mining areas, drilling contests were held to determine who could drill the deepest hole in solid rock in a fixed amount of time. Seated atop the Mother Lode with dozens of hard rock gold mines in the vicinity, Jackson in 1905 would have had hundreds of miners with the skills and brawn that were able to participate in such a contest.
Also see . . . The US Federal Highway Administration's web page on hand drilling. This webpage contains a descriptions, a glossary, and pictures and illustrations of hand drilling in hard rock. (Submitted on August 27, 2008.)
