PS a history angle is the first jackleg drill in Canada was used in 1945 at the Kerr Addison Mine. It was developed in Sweden. Canada has been slow to develop new technology in mining equipment and its only underground equip company that did trackless stuff, Jarvis Clark (Jarco) is long gone, beaten by the American company Wagner. Before 45 the standard drill was an air drill sometimes hand cranked to keep it at the face, which was called the leyner. Leyner Drill: Miner working with Jackleg Stoper drill for drilling "uppers" (holes in the "back" or roof of a shrinkage stope) Longhole drill for drilling long holes into larger-wider orebodies. plugger drill for drilling down holes underground diamond drill Slusher winch for leveling ore in a stope. You may say "happy, happy, joy, joy", here. Tugger hoist for getting equipment in and out of stope with a wooden "steel slide" Drill carrier. 16 to One refers to the ratio of the silver to gold price before 1880 Free silver at "16 to 1" would have expanded the money supply, but as a lone measure it would hardly have solved the nation's economic woes, and it would have (as Republicans argued) substantially raised the value of silver in relation to gold. Yet adherence of 'sound money' was not solely--or even primarily--responsible for the country's return to prosperity after 1896. To the extent that McKinley's victory reassured investors and financial institutions, whose leaders were frightened of Bryan, resolution of the issue may have had an indirect economic impact. After the campaign, however, the currency question faded quite rapidly from political debate.
