in his presence; and this disquietude was rather fed by the awful solitude in which he lived and the obscurity that hung about his occupations. His house was but a mile or two from ours, but very differently placed. It stood overlooking the road on the summit of a steep slope, and planted close against a range of overhanging bluffs. Nature, you would say, had here desired to imitate the works of man; for the slope was even, like the glacis of a fort, and the cliffs of a constant height, like the ramparts of a city. Not even spring could change one feature of that desolate scene; and the windows looked down across a plain, snowy with alkali, to ranges of cold stone sierras on the north. Twice or thrice I remember passing within view of this forbidding residence; and seeing it always shuttered, smokeless, and deserted, I remarked to my parents that some day it would certainly be robbed. ‘Ah, no,’ said my father, ‘never robbed;’ and I observed a strange conviction in his tone. At last, and not long before the blow fell on my unhappy family, I chanced to see the doctor’s house in a new light. My father was ill; my mother confined to his bedside; and I was suffered to go, under the charge of our driver, to the lonely house some twenty miles away, where our packages were left for us. The horse cast a shoe; night overtook us halfway home; and it was well on for three in the morning when the driver and I, alone in a light waggon, came to that part of the road which ran below the doctor’s house. The moon swam clear; the cliffs and mountains in this strong light lay utterly deserted; but the house, from its station on the top of the long slope and close under the bluff, not only shone abroad from every window like a place of festival, but from the great chimney at the west end poured forth a coil of smoke so thick and so voluminous, that it hung for miles along the windless night air, and its shadow lay far abroad in the moonlight upon the glittering alkali. As we continued to draw near, besides, a regular and panting throb began to divide the silence. First it seemed to me like the beating of a heart; and next it put into my mind the thought of some giant, smothered under mountains and still, with incalculable effort, fetching breath. I had heard of the railway, though I had not seen it, and I turned to ask the driver if this resembled it. But some look in his eye, some pallor, whether of fear or moonlight on his face, caused the words to die upon my lips. We continued, therefore, to advance in silence, till we were close below the lighted house; when suddenly, without one premonitory rustle, there burst forth a report of such a bigness that it shook the earth and
