One night, after journeying for a long time, we camped in one of these little mountain burgs, taking full possession, so that there should be no treachery while it was dark. The night passed quietly, for even fifty miles beyond Peking the terror lies heavy on the land, and in the morning we wandered to the massive iron-clad gates and the tall watch-towers which stood sentinel on either side to see if there was anything to be had. How old these were, how very old! For, mounting the staircase leading to the towers, we found that, although the rude rooms beneath showed signs of having been recently occupied, the stone steps which led to the roof-chambers were covered with enormous cobwebs and great layers of dust, showing that nothing had been disturbed for very many years. That was as it should be. At the very top of one tower we discovered a locked door, and beating it in amid showers of dust, we penetrated a room such as a witch of mediaeval Europe would dearly have loved. Nothing but cobwebs, dust, flapping, grey-yellow paper and decay. It was immensely old. And yet we found something. For there were some chests hidden away, and prizing these open, we discovered great books of yellow parchment, so old and so sodden that they fell to pieces as soon as one touched them. They were in some Mongol or Manchu script. They, too, were centuries old. But there was something else--a great discovery. Beneath the books we found helmets, inlaid with silver and gold and embellished with black velvet trappings studded with little iron knobs. There were also complete suits of chain armour. It seemed to us in that early morning that we were suddenly discovering the Middle Ages, perhaps even the Dark Ages. For these things were not even early Manchu; they were Mongol; Mogul--the war-dress of conquerors whose bodies had been rotting in the dust for five, six, seven, eight, or even nine centuries. These relics had lain there undisturbed for all this time because China has been merely tilling the fields and neglecting everything else. In a curious mood we donned these suits and went down below clad as the conquerors of old. There were some Indian troopers waiting, and when they saw these things they exclaimed and muttered excitedly to one another, casting half-startled looks. These were the same trappings and war-dresses as in the days of the Great Moguls at Delhi. The very same. The conquerors who had swept across high Asia had worn such things, and every man from Northern India must have understood their meaning and message. As they looked the Indian troopers chattered and talked to one another in a growing excitement. It seemed as if we had suddenly dug up some links of the half-forgotten past which showed how the chain of armed men had been tightly bound by Genghis Khan and Batu Khan, and all the other great Khans, from the Great Wall of China all round Northern and Central Asia, until it had reached down over the Himalayas into India. It was very curious.
