It certainly cannot be inferred that by the _Seres_, in any of the above quotations, was meant the same people as the present Chinese; on the contrary, the probability is that it did not allude to this nation, and that the ancients had not the least knowledge of its existence. It appears from another passage in Pliny, that the best iron in the world was in _Sericum_, and that the Seres exported it with their cloths and skins. The iron of the Chinese, as I have had occasion to observe, is remarkably bad, and all their articles of peltry are imported. The first people that we know to have travelled into China was a colony of Jews who, according to the records kept by their descendants, and which I understood from some of the missionaries are corroborated as to the time by Chinese history, first settled there shortly after the expedition of Alexander had opened a communication with India. Nor is it at all improbable that this adventurous and industrious people were the first to carry with them, into their new country, the silk worm and the mode of rearing it, either from Persia, or some of the neighbouring countries. The Emperor _Kaung-shee_, in his observations on natural history, takes notice that the Chinese are greatly mistaken when they say that silk was an exclusive product of China, for that the upper regions of India have a native worm of a larger growth, and which spins a stronger silk than any in China. Although indeed ancient authors are silent as to the article of silk, there are grounds for supposing it was not unknown in Tangut and Kitai. Several expressions in the Bible warrant the opinion that silk was used in the time of Solomon, and the _vestes perlucidæ ac fluidæ Medis_ of Justin seem to convey a description of silken robes. This mode of the first introduction of silk into China is offered as mere conjecture, for which I have no other authority in support of, than what is here mentioned, with the circumstance of the Jews being settled chiefly in the silk provinces, and of their being at this time in considerable numbers near _Hang-tchoo-foo_, where they carry on the principal trade in this article, and have acquired the reputation of fabricating the best stuffs of this material that are made in China; nor do I know in what other way they could recommend themselves to the Chinese, so far as to have obtained the protection of this jealous government, and to be allowed to intermarry with the women of the country. It is true they have practised no underhand attempts to seduce the natives from their paternal religion, and to persuade them to embrace their own; and although they are not very famous for the cultivation of the sciences, yet they might have rendered themselves extremely useful in suggesting improvements in many of the arts and manufactures. Many of them, indeed, forsake the religion of their forefathers, and arrive at high employments in the state.
