It was the fourth of February in the year 1875. It had been a severe winter, and the snow lay deep in the gorges of the Gilmerton Mountains. The steam ploughs had, however, kept the railroad open, and the evening train which connects the long line of coal-mining and iron-working settlements was slowly groaning its way up the steep gradients which lead from Stagville on the plain to Vermissa, the central township which lies at the head of Vermissa Valley. From this point the track sweeps downward to Bartons Crossing, Helmdale, and the purely agricultural county of Merton. It was a single-track railroad; but at every siding—and they were numerous—long lines of trucks piled with coal and iron ore told of the hidden wealth which had brought a rude population and a bustling life to this most desolate corner of the United States of America.
For desolate it was! Little could the first pioneer who had traversed it have ever imagined that the fairest prairies and the most lush water pastures were valueless compared to this gloomy land of black crag and tangled forest. Above the dark and often scarcely penetrable woods upon their flanks, the high, bare crowns of the mountains, white snow, and jagged rock towered upon each flank, leaving a long, winding, tortuous valley in the centre. Up this the little train was slowly crawling.
