Finally, about the middle of the afternoon, he was cheered for the first time by an unexpected glimpse of his goal. For several miles he had been following a rough trail which wound around the side of a steep, irregular hill. Coming out abruptly on a little plateau, with the tumbled rocks rising at his back, there spread out suddenly before him to the east a wide, extended sweep of level country.
At first he could scarcely believe that the sandy stretch below him was the north pasture he was seeking. But swiftly he realized that the threadlike line a little to the south must be the fence dividing the desert from the fertile portions of the Shoe-Bar, and he even thought he recognized the corner where the infected steer had been driven through. With an exclamation of satisfaction he was reaching for his field-glasses when of a sudden a strange, slowly-moving shape out in the desert caught his attention and riveted it instantly.
For a few seconds Buck thought his eyes were playing tricks. Amazed, incredulous, forgetting for an instant the field-glasses in his hand, he stared blankly from under squinting lids at the incredible object that crawled lurchingly through the shimmering, glittering desert atmosphere.
"I'm dotty!" he muttered at length. "It can't be!"
Then, remembering the glasses, he raised them hastily to his eyes and focused them with a twist or two of practised fingers.
He was neither crazy nor mistaken. Drawn suddenly out of its blurred obscurity by the powerful lenses, there sprang up before Buck's eyes, sharp and clear in every detail, a big gray motor-car that moved slowly but steadily, with many a bump and sidewise lurch, diagonally across the cactus-sprinkled desert below him.
The discovery galvanized Stratton into instant, alert attention. Motor-cars were rare in this remote range country and confined almost solely to the sort of "flivver" which is not entirely dependent on roads. The presence in the north pasture of this powerful gray machine, which certainly did not belong in the neighborhood, was more than significant, and Buck tried at once to get a view of the occupants.
In this he was not successful. There were three of them, one in the driver's seat and two others in the tonneau. But the top prevented more than a glimpse of the latter, while the cap and goggles of the chauffeur left visible only a wedge of brick-red, dust-coated skin, a thin, prominent nose and a wisp of wiry black mustache.
