As there were no other passengers (save Petie Trone, Esq., asleep in his travelling basket), Abram, the negro driver, gave up the reins with a grin. Taking his station on the step, he then admonished the volunteer from time to time as follows: "Dish yere's a bad bit; take keer, boss." "Jess ahead de rail am splayed out on de lef'. Yank 'em hard to de right, or we'll sut'ny run off de track. We ginerally _do_ run off de track 'bout yere." On each side was a dense forest veiled in the gray long moss. Could that be snow between the two black lines of track ahead? No snow, however, was possible in this warm atmosphere; it was but the spectral effect of the moonlight, blanching to an even paler whiteness the silvery sand which formed the road-bed between the rails. This sand covered the sleepers to such a depth that the mules could not step quickly; there was always a pailful of it on each foot to lift and throw off. They moved on, therefore, in a sluggish trot, the cow-bells attached to their collars keeping up a regular tink-tank, tink-tank. The tableau of her husband driving these spirited steeds struck Ruth as comical. She was seated on a camp-stool by his side, and presently she broke into a laugh. "Oh, you do look _so_ funny, Horace! If you could only see yourself! You, so particular about horses that you won't drive anything that is not absolutely perfect, there you stand taking the greatest pains, and watching solemnly every quiver of the ear of those old mules!" They were alone, Abram having gone to the baggage-car to get his tin horn. "Come, now, are you never going to stop making fun of me?" inquired Chase. "How do you expect to hit St. Augustine to-night if this fast express runs off the track?" But in spite of his protest, it was easy to see that he liked to hear her laugh. Abram, coming back, put the horn to his lips and blew a resounding blast; and presently, round a curve, the half-way station came into view--namely, a hut of palmetto boughs on the barren, with a bonfire before it. The negro station-men, beguiling their evening leisure by dancing on the track to their own singing and the music of a banjo, did not think it necessary to stop their gyrations until the heads of the mules actually touched their shoulders. Even then they made no haste in bringing out the fresh team which was to serve as motive power to St. Augustine, and Mr. and Mrs. Chase, leaving the car, strolled up and down near by. The veiled forest had been left behind; the rest of the way lay over the open pine-barrens. The leaping bonfire, the singing negroes, and the little train on its elevated snow-like track contrasted with the wild, lonely, silent, tree-dotted plain, stretching away limitlessly in the moonlight on all sides. "Perhaps Petie Trone, Esq., would like to take a run," said Ruth. Hastening into the car with her usual heedlessness, she tripped and nearly fell, Chase, who had followed, catching her arm just in time to save her.
