As the supply of whisky was very limited, and the throats down which it was poured were innumerable, it was found necessary to create some sort of a supply to meet the demand. This concoction was known as "hooch"; and disgusting as it is, it is doubtful if it is much more poisonous than the whisky itself. [M.H.E. Hayne, "The Pioneers of the Klondyke," London, 1897]
