"Cheyenne Country," said one of the oldest Indians. "Over there"--he pointed to a white thread that dipped and sidled along the easy roll of the hills--"is the Taos Trail. It joins the Santa Fe at the Rio Grande and goes north to the Big Muddy. It crosses all the east-flowing rivers near their source and skirts the Pawnee Country."

"And who are you--Cheyennes or Arapahoes?" Oliver could not be sure, though their faces and their costumes were familiar.

"CheyennesandArapahoes," said the oldest Dog Dancer, easing himself down to the buffalo robe which one of the rank and file of the warriors had spread for him. "Camp-mates and allies, though we do not call ourselves Cheyennes, you know. That is a Sioux name for us,--Red Words, it means;--what you call foreign-speaking, for the Sioux cannot speak any language but their own. We call ourselves Tsis-tsis-tas, Our Folk." He reached back for his pipe which a young man brought him and loosened his tobacco pouch from his belt, smiling across at Oliver, "Have you earned your smoke, my son?"

"I'm not allowed," said Oliver, eyeing the great pipe which he was certain he had seen a few moments before in the Museum case.

"Good, good," said the old Cheyenne; "a youth should not smoke until he has gathered the bark of the oak."

Oliver looked puzzled and the Dog Warrior smiled broadly, for gathering oak bark is a poetic Indian way of speaking of a young warrior's first scalping.

"He means you must not smoke until you have done something to prove you are a man," explained one of the Arapahoes, who was painted bright red all over and wore a fringe of scalps under his ceremonial belt. Pipes came out all around the circle and some one threw a handful of sweet-grass on the fire.

"What I should like to know," said Oliver, "is why you are called Dog Dancer?"

The painted man shook his head.

"All I know is that we are picked men, ripe with battles, and the Dog is our totem. So it has been since the Fathers' Fathers." He blew two puffs from his pipe straight up, murmuring, "O God, remember us on earth," after the fashion of ceremonial smoking.
