The Aztec Treasure-House by Thomas A. Janvier

As we rounded a mountain spur that extended a long way out into the lake, a deep bay opened to us; which bay ran close in to the cliffs whereby the valley was surrounded, and was at no great distance from the Barred Pass, through which we had made our entry. At the foot of the bay, built partly upon the level land near the water-side, and partly upon the steep ascent beyond, was the town of Huitzilan -- whereof the most curious feature that at first was noticeable was a tall chimney, whence thick black smoke was pouring forth, that rose above a stone building of great solidity and of a very considerable size.

On archaeological grounds, the sight of this chimney greatly astonished me; and Rayburn, who was a very well-read man in all matters connected with his profession, was greatly astonished by it also; for the chimney obviously was a part of extensive reduction-works, and we both knew that such complete appliances for the smelting of metal, as seemed from this sign to exist here, were supposed to be the product of a high state of civilization in comparatively modern times. As for Young, he declared that the chimney gave him a regular jolt of homesickness; for, excepting that it was built of stone instead of brick, it might have been, for the look of it, transplanted hither directly from the region of the Back Bay. "I s'pose we'll be hearin' th' noon whistle next," he said, mournfully; and presently he added: "Do you know, Professor, I b'lieve I'm beginnin' t' see daylight in all this tall talk you say th' Colonel has been givin' us about th' 'rebellions,' as he calls 'em, that go on here. He don't mean t' close our eyes up, th' Colonel don't, for he's a first-class gentleman; but, bein' born an' bred a heathen, he don't know any better. What he's tryin' t' tell us about, an' can't, because he don't know th' English for it, is _strikes_. That's what's th' matter. Miners are bound t' go on strikes. It's their nature, an' they can't help it. That chimbly gives th' whole thing away. You just tell th' Colonel that we've got down t' th' hard-pan an' really know what he's been drivin' at. An' t' think of there bein' strikes in Mexico! I didn't b'lieve that a Greaser had backbone enough, or ambition enough, t' strike at anything!"
