“Wherever there is oil, there were Indians once,” he announced. “Ask any oil man and he will tell you. At Lake Erie, in Pennsylvania and some parts of New York State, where dwelt the Iroquois, many years after oil was found. It is true, for I have read and heard it.”

“Were the Iroquois in New York State?” asked Bob interestedly. “I’ve always read of the Mohawks, but not about them.”

The Indian glanced at him gravely.

“The Mohawks were an Iroquois tribe,” he explained courteously. “Mohawks, Senecas, Tionontati, Cayuga, Oneida—all were tribes of the Iroquois. Yes I see you recognize those names—many places in this country have been named for Indians.”

“Are you an Iroquois?” asked Betty, rather timidly, for she feared lest the question should be considered impolite.

“I am a Kiowa,” announced the redman proudly. “Oklahoma and Kansas were the home of the Kiowas, the Pawnees and the Comanches. And you see oil has been found here. In Texas, where the big oil fields are, once roved Wichitas. The Dakotas, some tribes of which were the Biloxi, the Opelousas and the Pascagoulas, lived on the gulf plains of Louisiana. Out in southern California, where the oil wells now flow, the Yokut Indians once owned the land. They tell me that where oil had been discovered in Central America, petroleum seeps to the surface of the land where once the Indian tribes were found.”

“Did the Indians use the oil?” asked Bob. He, like Betty, was fascinated with the musical names of the mysterious tribes as they rolled easily from the Kiowa’s tongue.

“Not as the white man does,” was the answer. “The Senecas skimmed the streams for oil and sometimes spread blankets over the water till they were heavy with the oil. They used oil for cuts and burns and were famed for their skill in removing the water from the oil by boiling. Dances and religious rites were observed with the aid of oil. The Siouan Indians, who lived in West Virginia and Virginia, knew, too, of natural gas. They tossed in burning brands and watched the flames leap up from pits they themselves had dug.

“You will find,” the Indian continued, evidently approving of the rapt attention of his audience, “many wells now owned by Indians and leased to white-men companies. The Osage have big holdings. They are reservation Indians, mostly—perhaps they can not help that. I must go to the plowing.”

He gathered up his harness and went off to the field, and Bob and Betty resumed their explorations, talking about him with interest. Their tour of the shabby outbuildings was soon completed, and just in time for a huge bell rung vigorously announced that dinner was on the table.
