Watching her daughter, Emma noticed that something had changed. Barbara's eagerness for what was to come seemed somehow dimmed by the events at Laramie. She sat quietly, submissively, lost in thought. What was going on inside that lovely young head? Emma sighed. No one could guess, and least of all, perhaps, Barbara herself.

There was about a foot of snow. But though the weather had not been bitterly cold, it had lingered below the freezing point. There had been no thaw, and therefore there was no crust to break. The snow was still soft, and the wagon left deep ruts in its wake. The mules pulled steadily, and Joe swung them from side to side so that they might take turns walking in the already-broken trail left by the cavalry patrol. A pair of crows winged across the Trail, alighted in a solitary pine, and cawed raucously. About to answer them, Joe was halted by Tad's excited,

"Pa, look!"

To one side was a small cabin built at the base of a knoll, and as Joe turned a buffalo came from behind the knoll to stare curiously at the wagon. Another followed, and another. Then the rest of the herd came in sight and twenty-two buffaloes stood in the snow. Tad gulped, and looked longingly at the rifle, but they'd bought beef at Laramie and had all they needed. To shoot a buffalo now would be only for the sake of shooting something, and a waste of powder, shot and meat. Joe did not believe in that. The buffalo herd watched the wagon for a moment, then fell to pawing snow so that they might uncover the grass beneath.

Joe grinned, and he heard Barbara chuckle. Emma turned in the seat for a better look as they drove past. Sighting the buffalo brought back things that had been, and once again put them in tune with a roving life. The children began to giggle and chatter as they started a game. Tad leaned against the seat, staring intently at what lay ahead and on both sides, but saying nothing.

Rested, and on not too difficult a trail despite the snow, the mules set a brisk pace. Joe let them have their way, watching them only casually. Mules had what some people—who knew a little about them but seldom drove them—called a sense of humor. Others, better acquainted with mules, knew that they were merely full of deviltry. They did delight in confounding their drivers but they liked to have the advantage of any situation. It was a lot easier to snarl a harness when they were hitched to a plow than it was with a wagon tongue between them, and they knew it. Only occasionally, when the driver became too lax, did they try any tricks when they were pulling a loaded wagon.

Mike, who had padded steadily behind or at one side of the wagon, bounced ahead suddenly. He bristled, and a deep snarl rumbled in his chest. Keeping in the tracks of the cavalry patrol, he ran about fifty feet down the trail and halted. Joe stopped the wagon.

"Call your dog," he told Tad.

"Gee! What's comin'?"

"I don't know. Call your dog."
