"I guess we're up against another thunderstorm," he said. "My opinion of the mid-continental climate is singularly mean, but I'd put this strip of Canada near the limit. Our Texan northers are fierce when they come along; but here it blows all the time."

"We'll make camp, if you like; I don't feel very fresh," Blake replied.

"Not here," snapped Harding. "Where I stop I sleep, and I'm not particularly enthusiastic about sheltering under the cart. Last time we tried it the pony stampeded and the wheel went over my foot. The tent's no good; you'd want a chain to stop its blowing away. We'll go on until we bring up to lee of a big, solid bluff."

"Very well," Blake agreed. "I dare say we ought to find one in the hollow we got a glimpse of from the last rise; but we haven't had to put up with much discomfort yet."

"That's a matter of opinion. You haven't limped forty miles on a bad foot; but I'm not complaining. It's a whole lot to feel that we have started; doing nothing takes the sand out of me."

Blake had once or twice suggested that his comrade should ride, but the pony was overburdened and Harding refused. He explained that they could not expect to sell it at the settlement if it were in a worn-out condition; but Blake suspected him of sympathy for the patient beast.

They crossed the ridge and, seeing a wavy line of trees in the wide hollow, quickened their pace. The soil was firmer, the scrub through which the wheels crushed was short, and the trail led smoothly down a slight descent. This was comforting, for half the sky was barred with leaden cloud and the parched grass gleamed beneath it lividly white, while the light that struck a ridge-top here and there had a sinister luridness. It was getting cold and the wind was dropping; and that was not a favorable sign.

Pushing the cart through the softer places, dragging the jaded pony by the head, they hurried on and at last plunged through a creek with the trees just beyond. A few minutes later they tethered the pony to lee of the cart, and set up their tent. While Blake was rummaging out provisions, and Harding searching the bluff for dry sticks, they heard a beat of hoofs and a man rode up, leading a second horse. He got down and hobbled the horses before he turned to Blake.

"From the south? You're for Sweetwater?" he asked.

"Yes. How much farther is it?"
