Wood and coal, gas and oil, electricity even, aid us in our demand for warm houses. In winter we should suffer greatly were it not for our fireplaces, our stoves, and our furnaces. The sun then shines but a short time every day, and sends us little heat. In summer "the great orb of day" remains many hours in the heavens, and warms us through and through. We have little desire then for artificial heat; natural heat is sometimes more than sufficient. The sun shines over all the world. "His going forth is from the end of the heaven, and his circuit unto the ends of it: and there is nothing hid from the heat thereof." The sun does much more for us than send us its heat-rays: all day long we rejoice in the bright sunshine. But at night, when the sun has set, we ask for artificial light. How shall we get it? How did our ancestors obtain it? We have in our day the electric light; we can use illuminating gas; kerosene is easily obtained; if necessary, we can resort to candles. Yet there was a time when the electric light had not been discovered. Earlier still, gas had not been made and kerosene was not known. Indeed, long, long ago even candles had not been seen by men. What did the people do for light on a dark night in those times? After the sun had set and night had settled down upon them, what could they do during the long winter evenings without some method of lighting up the darkness? [Illustration: INDIANS TRAVELING AT NIGHT.] As we looked to the American Indians for the simplest and rudest methods of obtaining heat, so we can also learn something from them of the primitive modes of lighting. Much of the time the red men found sufficient light for all their wants in the wood fire. They needed no candles to read by, for they had no books nor papers. They cared for no lamp to dress by; they sought no illumination for halls or churches or theatres. What little need they had for artificial light was practically satisfied by that which came from the blazing logs. If, however, on any special occasion they wished to light up their long houses more brightly, the Indians used pitch-pine knots. In case they were traveling by night and did not care to proceed stealthily or secretly, these fagots of pitch pine gave them all the light they wanted. The light from these sticks was dim; it flickered so as to hurt the eyes; more smoke was given out than light; but the savage was fully content. Long before the red men were known, however, the burning fagot was used by the people of Europe and Asia to lessen the darkness of the night.
