She re-read the message—

Have heard nothing from you. Am anxious. Is all well with you? Telegraph answer to address given in letter.

Dr. Harpe tore the telegram in bits and watched the pieces flutter into the waste-basket.

"The Old Boy certainly looks after his own, Harpe," she murmured, but her fingertips were cold with nervousness.

Dr. Harpe had paid her professional visit and her horses were dragging the buggy through the deep sand in the direction of Dubois's sheep-ranch, where she contemplated staying for supper and driving home in the cooler evening. The small matter of being unwelcome never deterred Dr. Harpe when she was hungry and could save expense.

There was no one in sight nor human habitation within her range of vision; the slow drag was monotonous; the flies were bad and the heat was great; she was both drowsy and irritable.

"Lord! how I hate the smell of sheep!" she said fretfully as the odor rose strong from a bedding-ground, "and their everlastin' bleat would set me crazy. Gosh! it's hot!

The muffled sound of galloping hoofs in the sand caused her to raise her chin from her chest and her mind became instantly alert.

Instantly they pulled their horses on their haunches and swung them with rein and spur into the deep washout in the gulch where the giant sagebrush hid them.

It was so quickly done that Dr. Harpe had only a glimpse of flashing eyes, swarthy skins, and close-cropped, coal-black hair, but the glimpse was sufficient to cause her to say to herself—
