The French Jesuit missionary to whom, above any one else, is due the credit of first describing to the people of the West the nature of porcelain and how it was made, was living, at the time when the earliest of his famous letters was written (in 1712), at Jao-chau, the capital of the district. The letter is addressed to the _procureur_ of the order in Paris, and it would seem that it was before long made public.[77] It was followed in 1722 by a second supplementary letter, dated this time from King-te-chen itself. The Père D’Entrecolles had already been many years in China, and had before this sent home important letters on other branches of Chinese industry. The first letter on porcelain gives proof of long acquaintance with the subject, and it is not impossible that he may already have corresponded with some one in Europe on the same subject. I make this suggestion in connection with the curious coincidence of date between the residence of D’Entrecolles in this district and the first manufacture of porcelain in Saxony. These letters were naturally read with avidity at this time in Paris and elsewhere. The seed fell on fertile ground, and but one thing was wanting, and that was--some actual specimens of the materials described by the Jesuit father. The indications on this head, given in the letters, were indeed quite insufficient, and would rather tend to put inquirers on a false scent. The writer, for example, had no notion of the real nature of kaolin, a substance which in one place he compares to chalk. On the other hand, the technical details so fully given were at that time new. Since then this information has filtered down through many books, so that much of it now appears quite trite. I will confine myself to a few extracts bearing on points of interest that I may have overlooked elsewhere. These letters are written in the clear, flowing language of the time, and they are delightful reading. After giving some account from the _Annals of Fouliang_ of the early history of porcelain, and describing how the industry was gradually concentrated at King-te-chen, the Père D’Entrecolles goes on to say: ‘Apart from the pottery that is made all over China, there are a few other provinces, as those of Fukien and Canton, where porcelain is made.’ By Canton, in this case, we must understand, I suppose, the province of Kuang-tung, and this is a piece of information of some interest. The attempts made to establish workmen from King-te-chen at Pekin, and again in the neighbourhood of Amoy, from which port so large a commerce was already carried on with Europe, had, he says, wholly failed.
