"Shall I walk too?" she asked, wondering whether the act of walking would tend to steady her wavering fancies, and to stop that horrible tendency to light-headedness which bothered her so badly.

"I think not; you must be quite tired enough without adding to your fatigue by scrambling along this dusty track. Hullo!"

Nealie saw a sudden swerve on the part of Rocky, then the doctor's cane came cutting through the air, and there was a great wriggling and commotion on the dusty ground; but the doctor was so busy soothing the horse that he did not even answer when she called out to know what was the matter.

"Was it a snake?" she asked, as the cart was dragged forward at a jerk, and Rocky, prancing along on two legs, snorting and plunging, took all the doctor's skill to keep him from bolting in sheer fright.

"Yes; and I am very glad that you were not walking, for they are not pleasant creatures to meet," replied the doctor, thinking how fortunate it was that he happened to be on foot at the moment, and with a stick in his hand, for the snake was of a very deadly kind, and the horse would have stood no chance at all against the poison of its forked tongue.

Nealie shivered and sat suddenly straight up; it seemed as if the little shock had restored her in some strange way. The fiercest heat of the sun was past, and the raging of that terrible wind had dropped to a gentle breeze which blew cool and refreshing from another quarter. Indeed she would have felt quite cheerful had it not been for the menace of that smoke haze lying in a cloud along the line of the hills.

Another half-hour and they were crossing the top of the ridge, while Latimer, most snugly placed, lay on the slope of the other side. But at first sight of the town both Nealie and the doctor had burst into exclamations of horror, for it looked as if it had been burned out. A cloud of smoke from the ruined houses hung thickly over the place, and Rockefeller, with a horse's objection to facing fire, turned about on the track and showed so much disposition to go back by the way he had come that the doctor had to get down again and lead the scared creature.

Presently they saw a man just ahead of them, the first human being they had glimpsed for hours, and calling to him the doctor asked what had happened.

"It has been a fire," said the man, which, considering the smoke rising in all directions from the ruins, was rather an unnecessary explanation.

"So I see; but what started it?" asked the doctor.
