of special jiggered shoring techniques known as Diedesheimer square-sets, which became a standard for mines everywhere. This problem solved, another immediately took its place. As the shafts went deeper and deeper, some to 2600 feet, the air grew hotter, often exceeding 120 degrees. The stale air was barely breathable and so denuded of oxygen was it that the candles at that depth burned only with a flickering blue glow, instead o f a bright orange. The miners could work but fifteen minutes out o f every hour in that intense heat. Ice continually was transported to them in the shafts and each miner used up about 95 pounds o f the ice/ water mix in a shift. Despite the use of fans, ventilation was extremely poor, and the condidions wrought havoc on the men. Dangers were everywhere and the work was gruelling. Fires were commonplace, since so much timber was in the mines and explosions from black powder (later, dynamite, blasting caps, and low voltage detonators) crippled many. The tamping o f the powder and the crimping of the blasting caps were moments o f severest hazard. Moreover, over a period of time, the numerous blasts produced severe hearing impairment. Flooding was frequent as new tunnels were dug. Also, men were commonly scalded by sudden, steaming, hot-water springs breaking through the walls. Hernias were common and many wore the popular bulb belt to hold them in, especially in the case o f the muckers, men who loaded and pushed the ore carts out o f the mine. Their usual quota was 16 cars loaded and pushed out each eighthour shift. Those who chiselled and drilled in hard-rock mining, some times granite, gave the world the memorable phrase, “Deep Enough!” It came to refer not only to the hole drilled, but meant, in effect, “That’s as far as I go,” or, “I’ve had it for now,” or “I ’ve reached my limit—any more and you can shove it!” Eventually, heavy, compressed-air drills replaced much of the hand work required by 65
