"Wake! Wake!" said the Bull Buffalo, with a roll to it, as though the word had been shouted in a deep voice down an empty barrel. He shook the dust out of his mane and stamped his fore-foot to set the herd in motion. There were thousands of them feeding as far as the eye could reach, across the prairie, yearlings and cows with their calves of that season, and here and there a bull, tossing his heavy head and sending up light puffs of dust under the pawings of his hoof as he took up the leader's signal.

"Wake! Wa--ake!"

It rolled along the ground like thunder. At the sound the herds gathered themselves from the prairie, they turned back from the licks, they rose upplopfrom the wallows, trotting singly in the trails that rayed out to every part of the pastures and led up toward the high ridges.

"Wa-ak--" began the old bull; then he stopped short, threw up his head, sniffing the wind, and ended with a sharp snort which changed the words to "What? What?"

"What's this," said the Bull Buffalo, "Pale Faces?"

"They are very young," said the young cow, the one with thegoing look. She had just been taken into the herd that season and had the place of the favorite next to the leader.

"If you please, sir," said Oliver, "we only wished to know where the trail went."

"Why," said the Buffalo Chief, surprised, "to the Buffalo roads, of course. We must be changing pasture." As he pawed contempt upon the short, dry grass, the rattlesnake, that had been sunning himself at the foot of the hummock, slid away under the bleached buffalo skull, and the small, furry things dived everywhere into their burrows.

"That is the way always," said the young cow, "when the Buffalo People begin their travels. Not even a wolf will stay in the midst of the herds; there would be nothing left of him by the time the hooves had passed over."

The children could see how that might be, for as the thin lines began to converge toward the high places, it was as if the whole prairie had turned black and moving. Where the trails drew out of the flat lands to the watersheds, they were wide enough for eight or ten to walk abreast, trodden hard and white as country roads. There was a deep, continuous murmur from the cows like the voice of the earth talking to itself at twilight.

"Come," said the old bull, "we must be moving."

"But what is that?" said Dorcas Jane, as a new sound came from the direction of the river, a long chant stretching itself like a snake across the prairie, and as they listened there were words that lifted and fell with an odd little pony joggle.

"That is the Pawnees, singing their travel song," said the Buffalo Chief.

And as he spoke they could see the eagle bonnets of the tribesmen coming up the hollow, every man mounted, with his round shield and the point of his lance tilted forward. After them came the women on the pack-ponies with the goods, and the children stowed on the travoises of lodge-poles that trailed from the ponies' withers.

"Ha-ah," said the old bull. "One has laid his ear to the ground in their lodges and has heard the earth tremble with the passing of the Buffalo People."

"But where do they go?" said Dorcas.

"They follow the herds," said the old bull, "for the herds are their food and their clothes and their housing. It is the Way Things Are that the Buffalo People should make the trails and men should ride in them. They go up along the watersheds where the floods cannot mire, where the snow is lightest, and there are the best lookouts."

"And, also, there is the easiest going," said a new voice with a snarly running whine in it. It came from a small gray beast with pointed ears and a bushy tail, and the smut-tipped nose that all coyotes have had since their very first father blacked himself bringing fire to Man from the Burning Mountain. He had come up very softly at the heels of the Buffalo Chief, who wheeled suddenly and blew steam from his nostrils.

"That," he said, "is because of the calves. It is not because a buffalo cannot go anywhere it pleases him; down ravines where a horse would stumble and up cliffs where even you, O Smut Nose, cannot follow."

"True, Great Chief," said the Coyote, "but I seem to remember trails that led through the snow to very desirable places."

This was not altogether kind, for it is well known that it is only when snow has lain long enough on the ground to pack and have a hard coating of ice, that the buffaloes dare trust themselves upon it. When it is new-fallen and soft they flounder about helplessly until they die of starvation, and the wolves pull them down, or the Indians come and kill them. But the old bull had the privilege which belongs to greatness, of not being obliged to answer impertinent things that were said to him. He went on just as if nothing had interrupted, telling how the buffalo trails had found the mountain passes and how they were rutted deep into the earth by the migrating herds.

"I have heard," he said, "that when the Pale Faces came into the country they found no better roads anywhere than the buffalo traces--"

"Also," purred Moke-icha, "I have heard that they found trails through lands where no buffalo had been before them." Moke-icha, the Puma, lay on a brown boulder that matched so perfectly with her watered coat that if it had not been for the ruffling of the wind on her short fur and the twitchings of her tail, the children might not have discovered her. "Look," she said, stretching out one of her great pads toward the south, where the trail ran thin and white across a puma-colored land, streaked with black lava and purple shadow. Far at the other end it lifted in red, wall-sided buttes where the homes of the Cliff People stuck like honeycombs in the wind-scoured hollows.

"Now I recall a trail in that country," said Moke-icha, "that was older than the oldest father's father of them could remember. Four times a year the People of the Cliffs went down on it to the Sacred Water, and came back with bags of salt on their shoulders."

Even as she spoke they could see the people coming out of the Cliff dwellings and the priests going into the kivas preparing for the journey.

That was how it was; when any animal spoke of the country he knew best, that was what the children saw. And yet all the time there was the beginning of the buffalo trail in front of them, and around them, drawn there by that something of himself which every man puts into the work of his hands, the listening tribesmen. One of these spoke now in answer to Moke-icha.

"Also in my part of the country," he said, "long before there were Pale Faces, there were trade trails and graded ways, and walled ways between village and village. We traded for cherts as far south as Little River in the Tenasas Mountains, and north to the Sky-Blue Water for copper which was melted out of rocks, and there were workings at Flint Ridge that were older than the great mound at Cahokia."

"Oh," cried both the children at once, "Mound-Builders!"--and they stared at him with interest.

He was probably not any taller than the other Indians, but seemed so on account of his feather headdress which was built up in front with a curious cut-out copper ornament. They thought they recognized the broad banner stone of greenish slate which he carried, the handle of which was tasseled with turkey beards and tiny tails of ermine. He returned the children's stare in the friendliest possible fashion, twirling his banner stone as a policeman does his night stick.

"Were you? Mound-Builders, you know?" questioned Oliver.

"You could call us that. We called ourselves Tallegewi, and our trails were old before the buffalo had crossed east of the Missi-Sippu, the Father of all Rivers. Then the country was full of the horned people, thick as flies in the Moon of Stopped Waters." As he spoke, he pointed to the moose and wapiti trooping down the shallow hills to the watering-places. They moved with a dancing motion, and the multitude of their horns was like a forest walking, a young forest in the spring before the leaves are out and there is a clicking of antlered bough on bough. "They would come in twenty abreast to the licks where we lay in wait for them," said the Tallega. "They were the true trail-makers."

"Then you must have forgotten what I had to do with it," said a voice that seemed to come from high up in the air, so that they all looked up suddenly and would have been frightened at the huge bulk, if the voice coming from it in a squeaky whisper had not made it seem ridiculous. It was the Mastodon, who had strolled in from the pre-historic room, though it was a wonder to the children how so large a beast could move so silently.

"Hey," said a Lenni-Lenape, who had sat comfortably smoking all this time, "I've heard of you--there was an old Telling of my father's--though I hardly think I believed it. What are you doing here?"

"I've a perfect right to come," said the Mastodon, shuffling embarrassedly from foot to foot. "I was the first of my kind to have a man belonging to me, and it was I that showed him the trail to the sea."

"Oh, please, would you tell us about it?" said Dorcas.

The Mastodon rocked to and fro on his huge feet, embarrassedly.

"If--if it would please the company--"

Everybody looked at the Buffalo Chief, for, after all, it was he who began the party. The old bull pawed dust and blew steam from his nostrils, which was a perfectly safe thing to do in case the story didn't turn out to his liking.

"Tell, tell," he agreed, in a voice like a man shouting down twenty rain barrels at once.

And looking about slyly with his little twinkling eyes at the attentive circle, the Mastodon began.
