They were held up by the genial but exacting Tehachapi Hank at the foot of the grade, as on their last trip. Jo paid cash this time, and demanded a receipt, as ordered to do by Tweet.

As the wagon train neared the highest point in the pass she noticed that her whites and Hiram's blacks seemed to be lagging behind. Still, both teams seemed to be moving briskly enough and steadily. But the other teams were far in the lead.

Then Hiram's wagon entered upon a system of hairpin curves, and for nearly fifteen minutes none of her skinners was in sight.

She continued to wonder at the unwonted speed of the skinners ahead of Hiram.

Just as she reached the outmost point of a bow in the second hairpin curve, she heard a dull rumble behind her. Looking back, she saw nothing unusual, for in this place the road wound about U's and S's in the mountainside, and one could not see far along it, either ahead or behind. Deciding that a tree had fallen, she dismissed the matter from her thoughts, and gave her attention to manipulating the jerkline over an exacting piece of road.

She worked out of the curves eventually, to see the other teams moving placidly along ahead of her, but now she and Hiram had caught up again.

She spoke about it when they camped for the midday rest. It was Hiram who made reply.

"I was wondering at their speed, too, Jo," he said. "The rest of 'em were all way ahead of me and out o' sight for twenty minutes, maybe."

There followed a bantering conversation on the relative merits of the various teams, with minute explanation by the foremost skinners as to just why it was impossible for such miserable animals as the whites and the blacks to keep in sight of the rest. And for the time being, this ended the incident.

They left the delicately scented mountain country in due course and took up the long, weary journey over the desert. When they were near enough to the buttes to make out objects at their feet it became plain to all that the big outfit of Demarest, Spruce & Tillou had arrived and pitched its camp.
