I promised to be more orderly; and, indeed, I found afterwards the orders made for keeping all together were absolutely necessary for our common safety.
In two days more we passed the great China wall, made for a fortification against the Tartars: and a very great work it is, going over hills and mountains in an endless track, where the rocks are impassable, and the precipices such as no enemy could possibly enter, or indeed climb up, or where, if they did, no wall could hinder them.

They tell us its length is near a thousand English miles, but that the country is five hundred in a straight measured line, which the wall bounds without measuring the windings and turnings it takes; it is about four fathoms high, and as many thick in some places.
I stood still an hour or thereabouts without trespassing on our orders (for so long the caravan was in passing the gate), to look at it on every side, near and far off; I mean what was within my view: and the guide, who had been extolling it for the wonder of the world, was mighty eager to hear my opinion of it.

I told him it was a most excellent thing to keep out the Tartars; which he happened not to understand as I meant it and so took it for a compliment; but the old pilot laughed! "Oh, Seignior Inglese," says he, "you speak in colours."-- "In colours!" said I; "what do you mean by that ?"--"Why, you speak what looks white this way and black that way--gay one way and dull another.

You tell him it is a good wall to keep out Tartars; you tell me by that it is good for nothing but to keep out Tartars.

I understand you, Seignior Inglese, I understand you; but Seignior Chinese understood you his own way."-- "Well," says I, "do you think it would stand out an army of our country people, with a good train of artillery; or our engineers, with two companies of miners?
Would not they batter it down in ten days, that an army might enter in battalia; or blow it up in the air, foundation and all, that there should be no sign of it left ?"--"Ay, ay," says he, "I know that." The Chinese wanted mightily to know what I said to the pilot, and I gave him leave to tell him a few days after, for we were then almost out of their country, and he was to leave us a little time after this; but when he knew what I said, he was dumb all the rest of the way, and we heard no more of his fine story of the Chinese power and greatness while he stayed.
After we passed this mighty nothing, called a wall, something like the Picts' walls so famous in Northumberland, built by the Romans, we began to find the country thinly inhabited, and the people rather confined to live in fortified towns, as being subject to the inroads and depredations of the Tartars, who rob in great armies, and therefore are not to be resisted by the naked inhabitants of an open country.
