During the continuance of the Tartar government, which was not quite a century, great numbers of Mahomedans likewise found their way from Arabia to China. These people had long, indeed, been in the habit of carrying on a commercial intercourse with the Chinese; which, however, as at the present day, extended no further than the sea-ports on the southern coast. They now found no difficulty in getting access to the capital, where they rendered themselves particularly useful in adjusting the chronology of the nation, and making the necessary calculations for the yearly calendar. Having acquired the language and adopted the dress and manners of the people, by degrees they turned their thoughts to the extending of their religious principles, and bringing the whole country to embrace the doctrine of their great prophet. For this end, they bought and educated at their own expence such children of poor people as were likely to be exposed in times of famine; and they employed persons to pick up, in the streets of the capital, any infants that should be thrown out in the course of the night, and who were not too much weakened or otherwise injured to be recovered. About the middle of the sixteenth century, several Roman Catholic missionaries, of the order of Jesus, penetrated into the East; and the indefatigable zeal of one of these, Francis Xavier, carried him as far as _San-Shian_, a small island on the coast of China, where he died in the year 1552, in consequence of the uncommon fatigues he had undergone. His brother missionaries have calculated that he travelled, on foot, not less than one hundred thousand English miles, a great part of which was over mountains and desarts and forests and burning sands. Since a more easy communication with India and China has been effected by the way of the Cape of Good Hope, numbers of missionaries of the Catholic religion have volunteered their services into those countries; and although the sole object of their mission is the propagation of the Christian faith, they find it necessary, in order to forward that object, to make themselves useful to the government. In China, they are occasionally employed as astronomers, mathematicians, mechanics, and interpreters. "It must have appeared a singular spectacle," observes Sir George Staunton, "to every class of beholders, to see men actuated by motives different from those of most human actions, quitting for ever their country and their connexions, to devote themselves for life to the purposes of changing the tenets of a people they had never seen; and in pursuing that object to run every risk, suffer every persecution, and sacrifice every comfort; insinuating themselves, by address, by talent, by perseverance, by humility, by application to studies foreign from their original education, or by the cultivation of arts to which they had not been bred, into notice and protection; overcoming the prejudices
