It is usually found on sea-coasts, after storms, in rounded nodules; or, if scarce on shore, it is sought for by men clad in leather garments, who wade up to their necks in the sea, and scrape the sea-bottom with hooped nets attached to the end of long poles; or (rather dangerous work) men go out in boats, and examine the faces of precipitous cliffs, picking off, by means of iron hooks, the lumps of amber which they may see here and there. Sometimes a piece weighing nearly a pound is found, and a weight of even ten pounds is recorded. As small pieces can easily be joined by smoothing the surfaces, moistening them with linseed oil, and pressing them together over a charcoal fire, and as gum copal is sometimes very like amber, there is much sophistication indulged in, which none but an expert can guard against. In fashioning the nodules of amber, whether genuine or fictitious, into pipe mouth-pieces, they are split on a leaden plate in a turning lathe, smoothed into shape by whet-stones, rubbed with chalk and water, and polished with a piece of flannel. It is an especially difficult kind of work; for unless the amber is allowed frequent intervals for cooling, it becomes electrically excited by the friction and shivers into fragments; the men, too, are put into nervous tremors if kept too long at work at one time. Amber is one of the most electrically excitable of all known substances; in fact, the name electricity itself was derived from _electron_, the Greek name for amber. Hookahs, chibouques, narghiles, meerschaums, all are largely adorned with amber mouth-pieces. The mouth-piece often consists of two or three pieces of amber, interjoined with ornaments of gold and gems; it is in such case the most costly part of the pipe. At one of the greater industrial exhibitions four Turkish amames, or amber mouth-pieces, were shown, illustrating clearly enough the value attached to choice specimens; two of them were worth L350 each, two L200 each, diamond studded. The Turkish and Persian pipes have often a small wooden tube inside the amber mouth-piece. They require frequent cleaning with a long wire and a bit of tow, and in some large towns there are professional pipe-cleaners.
