Bucket Ropes for Wells.—I suffer from the serious misfortune of a well 325 feet deep. It is worked by two buckets, and a chain, which, from its great length, is necessarily very heavy. Would a wire rope (galvinised) answer? This, I presume, might be tight and thin; it would have to carry, at each end, a strong and heavy bucket, holding 12 gallons. The rope would have to work over, and, I presume, once quite round, a wheel only 14 inches in diameter. Would any of your correspondents have the charity to give the result of any actual experience of light wire rope; such would be of value, probably to others, as well as to myself. C.R.D.1
1 A reply appeared in the next issue of Gardeners' Chronicle (no. 3, 17 January 1852, p. 38): 'Wire Rope (see p. 22).— I certainly cannot recommend wire rope when it is required to work round a sheave, unless the diameter of the sheave or drum is at least 3 feet. One broke with me in a very few weeks, though only 10 feet long, and the weight at the end only 70 lbs., being worn and broken where it worked over the sheave. C.L.C'. See Correspondence vol. 5.
