I could not deny that he was right. I began to think over some of our modern improvements, and luckily thought of a candle. So I explained to him how candles were made of tallow, by dipping a string into the melted tallow. Nothing would satisfy him but an immediate trial. To my great triumph I succeeded in making a tolerable candle out of some animal fat. The chief was delighted.
"That," said he, "is a great invention. You indeed are fortunate people. We have only torches."
"But we don't use candles," I said; "we have gas, and kerosene-lamps, and the electric light. But I can't make any of those for you. I don't know where to find coal or oil, or how to make electricity, or an electric light."
"No matter," he said cheerfully; "this is quite enough. I see there is some truth in your story. Tell me more of your marvels."
"Well," I said, "we use the steam-engine for traveling. We heat water over the fire, and a vapor or steam comes from it, and we let the steam go into a box, and it pushes a wheel around, and that pushes other wheels. That's the way we travel."
"Can you make a steam-engine?"
"No-o," I said. "I'm afraid I don't quite understand it."
"Well, what else?" the chief asked patiently.
"How do you tell time?" I inquired.

"Do you know how they work?"
"Not exactly," I said; "though I have a general idea."
"We might find these hard substances you call metals," said the
