They tell a story of Mainthong Peak and the Nats there, how all of a sudden, one day in 1885, strange noises came from the hill. High up on his mighty side was heard the sound of great guns firing slowly and continuously; there was the thunder of falling rocks, cries as of someone bewailing a terrible calamity, and voices calling from the precipices. The people living in their little hamlets about his feet were terrified. Something they knew had happened of most dire import to them, some catastrophe which they were powerless to prevent, which they could not even guess. But when a few weeks later there came even into those remote villages the news of the fall of Mandalay, of the surrender of the king, of the 'great treachery,' they knew that this was what the Nats had been sorrowing over. All the Nats everywhere seem to have been distressed at our arrival, to hate our presence, and to earnestly desire our absence. They are the spirits of the country and of the people, and they cannot abide a foreign domination. But the greatest place for Nats is the Popa Mountain, which is an extinct volcano standing all alone about midway between the river and the Shan Mountains. It is thus very conspicuous, having no hills near it to share its majesty; and being in sight from many of the old capitals, it is very well known in history and legend. It is covered with dense forest, and the villages close about are few. At the top there is a crater with a broken side, and a stream comes flowing out of this break down the mountain. Probably it was the denseness of its forests, the abundance of water, and its central position, more than its guardian Nats, that made it for so many years the last retreating-place of the half-robber, half-patriot bands that made life so uneasy for us. But the Nats of Popa Mountains are very famous. When any foreigner was taken into the service of the King of Burma he had to swear an oath of fidelity. He swore upon many things, and among them were included 'all the Nats in Popa.' No Burman would have dared to break an oath sworn in such a serious way as this, and they did not imagine that anyone else would. It was and is a very dangerous thing to offend the Popa Nats; for they are still there in the mountain, and everyone who goes there must do them reverence.
