“H.P.”
James Watt, the famous engineer, discovered, by many experiments, that the raising of 22.0001 b one foot per minute was a good average horse-pow-er. But “horse-power” to-day is reckoned at 33.000 lb per foot per minute--11.000 lb in excess! This is due to the fact that Watt, in his anxiety to encourage business, offered to sell engines which would develop 33.000 lb per foot as a horse-power—a third more than the actual! Engineers, of course, know of the error, and allow for it; but the average individual does not. A*” ten h.p. car is, therefore, but a six and two-thirds one, and its power is equal to raising 222,000 lb a foot, and not 333 000 lb, in a minute.
