The sunset light was fading when we reached the edge of the ravine in which the city lies.  It was like looking unawares over the edge of a precipice; the gulch opened beneath us as suddenly as if the earth had that moment parted and made it.  With brakes set firm, we drove cautiously down the steep road; the ravine twinkled with lights, and almost seemed to flutter with white tents and wagon tops.  At the farther end it widened, opening out on an inlet of the San Luis Park; and, in its center, near this widening mouth, lay the twelve-days-old city.  A strange din arose from it.

“What is going on?” we exclaimed.  “The building of the city,” was the reply.  “Twelve days ago there was not a house here.  To-day there are one hundred and five, and in a week more there will be two hundred; each man is building his own home, and working day and night to get it done ahead of his neighbor.  There are four sawmills going constantly, but they can’t turn out lumber half fast enough.  Everybody has to be content with a board at a time.  If it were not for that, there would have been twice as many houses done as there are.”

We drove on down the ravine.  A little creek on our right was half hid in willow thickets.  Hundreds of white tents gleamed among them:  tents with poles; tents made by spreading sailcloth over the tops of bushes; round tents; square tents; big tents; little tents; and for every tent a camp fire; hundreds of white-topped wagons, also, at rest for the night, their great poles propped up by sticks, and their mules and drivers lying and standing in picturesque groups around them.

It was a scene not to be forgotten.  Louder and louder sounded the chorus of the hammers as we drew near the center of the “city;” more and more the bustle thickened; great ox teams swaying unwieldily about, drawing logs and planks, backing up steep places; all sorts of vehicles driving at reckless speed up and down; men carrying doors; men walking along inside of window sashes,—­the easiest way to carry them; men shoveling; men wheeling wheelbarrows; not a man standing still; not a man with empty hands; every man picking up something, and running to put it down somewhere else, as in a play; and, all the while, “Clink! clink! clink!” ringing above the other sounds,—­the strokes of hundreds of hammers, like the “Anvil Chorus.”

“Where is Perry’s Hotel?” we asked.  One of the least busy of the throng spared time to point to it with his thumb, as he passed us.  In some bewilderment we drew up in front of a large unfinished house, through the many uncased apertures of which we could see only scaffoldings, rough boards, carpenters’ benches, and heaps of shavings.  Streams of men were passing in and out through these openings, which might be either doors or windows; no steps led to any of them.
