By noon we had come in sight of the mill: a great brown building, halfway up the hill, big as a factory, two stories high, and with tanks and ladders along the roof; which, as a pendicle of Silverado mine, we held to be an outlying province of our own. Thither, then, we went, crossing the valley by a grassy trail; and there lunched out of the basket, sitting in a kind of portico, and wondering, while we ate, at this great bulk of useless building. Through a chink we could look far down into the interior, and see sunbeams floating in the dust and striking on tier after tier of silent, rusty machinery. It cost six thousand dollars, twelve hundred English sovereigns; and now, here it stands deserted, like the temple of a forgotten religion, the busy millers toiling somewhere else. All the time we were there, mill and mill town showed no sign of life; that part of the mountainside, which is very open and green, was tenanted by no living creature but ourselves and the insects; and nothing stirred but the cloud manufactory upon the mountain summit. It was odd to compare this with the former days, when the engine was in full blast, the mill palpitating to its strokes, and the carts came rattling down from Silverado, charged with ore.
