Chinese are almost transparent, and look like horn in the inside; and the roots which are fit for use are heavy and compact in the inside. No one has ever discovered the Chinese method of preparing it. It is thought, among other preparations, they dip the roots in a decoction of the leaves of ginseng. Kalm wrote thus of the ginseng in 1749 (Kalm, in Pinkerton, vol. xiii., p. 639). Mr. Heriot mentions that "one article of commerce the Canadians had, by their own imprudence, rendered altogether unprofitable. From the time that Canada ginseng had been imported to Canton, and its quality pronounced equal to that of Corea or Tartary, a pound of this plant, which before sold in Quebec for twenty pence, became, when its value was once ascertained, worth one pound and tenpence sterling. The export of this article amounted in 1752 to L20,000 sterling. But the Canadians, eager suddenly to enrich themselves, reaped this plant in May when it should not have been gathered until September, and dried it in ovens when its moisture should have been gradually evaporated in the shade. This fatal mistake, arising from cupidity, and in some measure from ignorance, ruined the sale of their ginseng among the only people on earth who are partial to its use, and at an early period cut off from the colony a new branch of trade, which, under proper regulations, might have been essentially productive."--Heriot's _Travels through the Canadas_, p. 99, 1807. "Mountainous woods in Tartary are mentioned as the place where the ginseng is produced in the greatest abundance. In 1709, the emperor ordered an army of ten thousand men to collect all the ginseng they could find, and each person was to give him two ounces of the best, while for the remainder payment was to be made in silver, weight for weight. It was in the same year that Father Jartoux, a Jesuit missionary in China, prepared a figure and accurate description of the plant, in which he bears testimony to the beneficial effects of the root. He tried it in many instances himself, and always with the same result, especially when exhausted with fatigue. His pulse was increased, his appetite improved, and his whole frame invigorated. Judging from the accounts before us, we should say that the Chinese were extravagant in their ideas of the virtues of this herb; but that it is undoubtedly a cordial stimulant, to be compared, perhaps, in some degree, with the aromatic root of Meum athamanticum, so much esteemed by the Scottish Highlanders. It has nevertheless disappeared from our Materia Medica."--Murray's _Canada_, vol. iii., p. 308. Charlevoix, tom. vi., p. 24. "Ginseng a veritablement la vertu de soutenir, de fortifier, et de rappeller les forces epuisees."--Lafitau, tom. ii., p. 142.]
