Watch and Wait by Oliver Optic

At the period of which we write, the railroad through the Teche country had not been constructed, and the population was very sparsely scattered over this region. Most of the available land, however, was occupied; but, of course, none of the little villages which spring up around railroad stations, and which, in the course of years, grow into large towns and cities, had yet appeared.

With many doubts and fears in regard to the future, the young fugitives commenced the voyage to the Gulf. It was seventy miles from the camp, and it was absolutely necessary that the trip should be performed by night, for the lake, at the season of high water, was navigable for small steamers, which, with other craft, occasionally passed over its turbid tide. In the passage down, they were liable to meet some of these boats; and though the search for the runaways had long since ceased, the Isabel might be recognized, and the mystery of her singular disappearance explained.
