Several preliminary meetings are held by the representatives of both parties to decide the time, and the place of the match. It is also decided what property each party should stake. This has to be paid by the loser to the victor. For several days and nights before the contest, they gather their friends together; they make offerings and sing incantations to the spirits, and beg of them to support their just cause, and help their representative to win. Each party chooses a champion. There are many professional divers, who, for a trifling sum, are willing to take part in this painful contest. On the evening of the day previous to that on which the diving match is to take place, each champion is fed with seven compressed balls of cooked rice. Then each is made to lie down on a nice new mat, and is covered with a beautiful, Dyak-woven sheet; an incantation is made over him, and the spirit inhabitants of the waters are invoked to come to the aid of the man whose cause is just. Early the next morning the champions are roused from their sleep, and dressed each in a fine new waistcloth. The articles staked are brought down from the houses, and placed upon the bank. A large crowd of men, women and children join the procession of the two champions and their friends and supporters to the scene of the contest at the river-side. As soon as the place is reached, fires are lit and mats are spread for the divers to sit on and warm themselves. While they sit by their respective fires, the necessary preparations are made. Each party provides a roughly-constructed wooden grating, to be placed in the bed of the river, for his champion to stand on in the water. These are placed within a few yards of each other, where the water is deep enough to reach the waist, and near each a pole is thrust firmly into the mud for the man to hold on to while he is diving.
