From Dusun Folklore
Long ago the rainbow was a path for men. Those who lived up-country used the rainbow as a bridge when they wished to go down-country in search of wives. For though there were women up-country, the up-country men were very fond of the down-country women. Because of the men’s desire for wives from the coast they made the rainbow as a bridge, and you can see the floor and hand-rail of the bridge in the rainbow to the present day. The men when they had first made the rainbow to their homes. When they arrived up-country the marriages were celebrated with a feast, and the men became drunk. Then came a headman from another village and said to them: “You men are very clever; how long have I lived in this country, but never yet have I seen anything like your rainbow. Do you intend to leave it there or not?” The men replied: “When we want to go down-country with our wives we will put it in place, but when we do not want it we will take it away,” and thus they do to the present day. What the men were I do not know, but they were more than ordinary men. It is an old-time tale of our people. Perhaps it is true, for just now, as you saw, the rainbow vanished.
