With dawn, the first snow lay on the ground. It was light and powdery, little more than a white dust that did not hide completely the grass on the near-by knolls but seemed to cover entirely those farther away. Little snow devils, picked up by wind, whirled across the trail and filled ruts while leaving the crown between them brown and naked. Joe hurried the mules, and wished mightily that he had saved some grain for them. Mules worked better when they were on grain, but all they'd been able to carry from Independence had been used up two weeks ago. The rest of the trip to Laramie would necessarily be forced, with no time to linger on the way and since there wasn't any grain, the mules would have to work without it. Tad trotted beside the wagon and fell behind. Joe waited for him. "Better get in." "I aim to walk. I'll keep up." Joe felt his anger rise, but he held it in check. Tad had been mighty brave and mighty helpful and he was entitled to be treated with respect. "We're going to make time, Tad. We've got to now." Tad was silent, and the struggle he was undergoing showed plainly on his freckled face. Suddenly, without a word of comment, he climbed into the wagon and settled himself where he could watch out the back end. Joe's heart swelled with pride. Emma had told him that his daughter had grown up, and now he knew that his son was growing, too. Fiercely proud, Tad had fully intended to walk all the way to Oregon. But he had seen the need, and had placed the family's welfare above his own. Joe said, "Keep your eye peeled for antelope, will you? Holler if you see any and I'll hand you the rifle." "Sure, Pa. You want buffalo too?" "Can't stop to butcher a buffalo right now." Joe kept the mules at a fast walk except on upgrades and trotted them on all the down slopes. The mules were big, but their hoofs were slender and much smaller than a horse's. Therefore, though this light fall did not bother them, they would have harder going than horses found should there be deep snow. Clouds ruled the sky until almost noon, then they broke and the sun shone for a few hours. There was little warmth in it and the north wind still blew. But all the snow melted, leaving them a clear trail, and there had not been enough snow so that its melting left mud in its wake. That night they stopped half an hour before their usual stopping time because, though speed was important, grass was just as necessary and there was rich grass at this spot. The mules and the cow could eat their fill and be ready for a long trail tomorrow. The next day they started at dawn, and the day after that. On the seventh day after the first snowfall they met a rider coming east. Joe looked around to see where his children were, and he made sure that the rifle was in reach. Then they drew nearer and he saw that the rider was a white man.
