There is another world under this, and it is like ours in everything--animals, plants, and people--save that the seasons are different. The streams that come down from the mountains are the trails by which we reach this underworld, and the springs at their heads are the doorways by which we enter it, but to do this one must fast and go to water and have one of the underground people for a guide. We know that the seasons in the underworld are different from ours, because the water in the springs is always warmer in winter and cooler in summer than the outer air. When the animals and plants were first made--we do not know by whom--they were told to watch and keep awake for seven nights, just as young men now fast and keep awake when they pray to their medicine. They tried to do this, and nearly all were awake through the first night, but the next night several dropped off to sleep, and the third night others were asleep, and then others, until, on the seventh night, of all the animals only the owl, the panther, and one or two more were still awake. To these were given the power to see and to go about in the dark, and to make prey of the birds and animals which must sleep at night. Of the trees only the cedar, the pine, the spruce, the holly, and the laurel were awake to the end, and to them it was given to be always green and to be greatest for medicine, but to the others it was said: "Because you have not endured to the end you shall lose your hair every winter." Men came after the animals and plants. At first there were only a brother and sister until he struck her with a fish and told her to multiply, and so it was. In seven days a child was born to her, and thereafter every seven days another, and they increased very fast until there was danger that the world could not keep them. Then it was made that a woman should have only one child in a year, and it has been so ever since. 2. THE FIRST FIRE In the beginning there was no fire, and the world was cold, until the Thunders (Ani'-Hyûñ'tikwalâ'ski), who lived up in Galûñ'lati, sent their lightning and put fire into the bottom of a hollow sycamore tree which grew on an island. The animals knew it was there, because they could see the smoke coming out at the top, but they could not get to it on account of the water, so they held a council to decide what to do. This was a long time ago.
