Neander ascribes this invention to the Persians; but Magnenus rather attributes it to the Dutch and English, to the latter of whom attaches the credit of having invented the clay pipes of modern times. Some writers have concluded that the plant served as a narcotic in some parts of Asia. Liebault thinks it was known in Europe[32] many years before the discovery of the New World, and asserts that the plant had been found in the Ardennes. Magnenus, however, claims its origin as transatlantic and affirms as his belief that the winds had doubtless carried the seeds from one continent to the other. Pallos says that among the Chinese, and among the Mongol tribes who had the most intercourse with them, the custom of smoking is so general, so frequent, and has become so indispensable a luxury; the tobacco purse affixed to their belt so necessary an article of dress; the form of the pipes, from which the Dutch seem to have taken the model of theirs, so original; and, finally, the preparation of the leaves so peculiar, that they could not possibly derive all this from America by way of Europe, especially as India, where the practice of smoking is not so general, intervenes between Persia and China. Meyen also states that the consumption of tobacco in the Chinese empire is of immense extent, and the practice seems to be of great antiquity, "for on very old sculptures I have observed the very same tobacco pipes which are still used." Besides, we now know that the plant which furnishes the Chinese tobacco is even said to grow wild in the East Indies. [Footnote 32: James the First also inclines to this belief, declaring tobacco to be "a common herb which (though under divers names) grows almost everywhere."]
