The savage people showed the strangers a poor little booth to sleep in, and went away to their own lairs, with many prostrations, for they really thought them "children of the sun." Oello and her husband laughed very heartily when they knew they were alone. Oello made him promise to go in the morning early for potatoes, and oca, and mashua, which are two other tubers like potatoes which grow there. "And we will show them," said she, "how to cook them." For they had seen by the evening feast, that the poor savage people had no knowledge of the use of fire. So, early in the morning, he went up a little way on the lake shore, and returned with strings of all these roots, and with another string of fish he had caught in a brook above. And when the savage people waked and came to Oello's hut, they found her and her husband just starting their fire,--a feat these people had never seen before. He had cut with his copper knife a little groove in some soft palm-wood, and he had fitted in it a round piece of iron-wood, and round the iron-wood had bound a bow-string, and while Oello held the palm-wood firm, he made the iron-wood fly round and round and round, till the pith of the palm smoked, and smoked, and at last a flake of the pith caught fire, and then another and another, and Oello dropped other flakes upon these, and blew them gently, and fed them with dry leaves, till they were all in a blaze. The savage people looked on with wonder and terror. They cried out when they saw the blaze, "They are children of the sun,--they are children of the sun!"--and ran away. Oello and her husband did not know what they said, and went on broiling the fish and baking the potatoes, and the mashua, and the oca, and the ulloco. And when they were ready, Oello coaxed some of the children to come back, and next their mothers came and next the men. But still they said, "They are children of the sun." And when they ate of the food that had been cooked for them, they said it was the food of the immortals. Now, in Oello's home, this work of making the fire from wood had been called menial work, and was left to servants only. But even the princes of that land were taught never to order another to do what they could not do themselves. And thus it happened that the two young travellers could do it so well. And thus it was, that, because they did what they could, the savage people honored them with such exceeding honor, and because they did the work of servants they called them gods. As it is written: "He who is greatest among you shall be your servant."
