It has been remarked, that the three great discoveries of the magnetic needle, of gunpowder, and of printing, in Europe, followed close upon the return of the famous traveller Marco Polo. It was the boast indeed of Caung-shee to the Jesuits, when they instructed him in some of the sciences of Europe, that the latter country was neither acquainted with the mariner's compass, nor with the art of printing, nor with gunpowder, till they had been in common use in China near two thousand years. As to gunpowder, it is pretty obvious, that our countryman Roger Bacon was well acquainted with the ingredients that enter into its composition. In more than one part of his works he observes, that with saltpetre and other articles may be made a fire that will inflame to a great distance; and in one place he states, that with sulphur, saltpetre, and something else, which he disguises under two or three barbarous words, a composition may be made, by which the effects of thunder and of lightning may be imitated. Bacon died in the year 1292, and Marco Polo returned to Europe in 1295; so that he could not possibly have received any hint to lead towards the discovery through the channel of the Venetian traveller[18].

If the Chinese had, at any period of their history, been acquainted with the art of casting large cannon, and of making use of them in their wars, it is scarcely probable they would ever have lost it. Yet it is very certain the two Jesuits, Schaal and Verbiest, took great pains to instruct them in the method of casting cannon; in which, however, they have not made any progress or improvement. I observed, near one of the gates of Pekin, a few rude, ill-shapen, and disproportionate pieces, lying unmounted on the ground, and these, with some of the same kind on the frontiers of Canton, and a few pieces, apparently twelve pounders, at Hang-tcheu-foo, which had wooden pent-houses erected over each, were the only cannon that we noticed in the whole country. Whether the specimens, exhibited in the annexed plate, which were drawn by the late Captain Parish of the Royal Artillery, be originally of Chinese invention, or borrowed from some other nation, I cannot take upon me to decide; but such are the pieces which are sometimes found, scattered about the gates of some of their cities.

Mr. Bell, who visited China in the suite of the Russian Embassador, near a century ago, remarks, that "towards the western extremity of the Great Wall, he observed some hundreds of old cannon piled up in one of the towers, each composed of three or four pieces of hammered iron, joined and fastened together with hoops of the same metal." It is probable indeed that the Chinese, like the Hindoos, before the time of Schaal and Verbiest, made use of cannon of wrought iron, which were hooped together like those mentioned by Mr. Bell.

In making their salutes, of which they are not sparing, they invariably employ three small petards, or pistol-barrels rather, which are stuck erect in the ground; and in firing these small pieces the soldiers are so afraid, that they are discharged by a train laid from one to the other. When Captain Parish caused a few rounds to be fired from two field-pieces, which were among the presents for the Emperor, in as quick succession as possible, the Chinese officers very coolly observed, that their own soldiers could do it just as well, and perhaps better. And when Lord Macartney asked the Ex-viceroy of Canton if he would wish to see his guard go through the different evolutions as practised in Europe, he replied with equal indifference, "That they could not possibly be new to him, who had been so much engaged in the wars on the frontiers of Tartary;" though the chances are, that he had never before seen a firelock: with such ridiculous affectation of superiority, and contempt for other nations, does the unconquerable pride of this people inspire them. It seems, indeed, to be laid down as a general principle, never to be caught in the admiration of any thing brought among them by foreigners. Whenever a man of rank came to look at the presents, if observed by any of us, he would carelessly glance his eye over them, and affect as much indifference as if he was in the daily habit of viewing things of the same kind.
