The Oma-Sulings are pleasant to deal with, being bashful and unspoiled. The usual repulsive skin diseases are seldom seen, and the women are attractive. There appears to have been, and still is, much intercourse between the Oma-Sulings and their equally pleasant neighbours to the east, the Long-Glats. Many of the latter came to the feast and there is much intermarrying among the nobles of the two tribes. Lidju, my assistant and friend here, was a noble of the Long-Glats with the title of raja and married a sister of the great chief of the Oma-Sulings. She was the principal of the numerous female blians of the kampong, slender of figure, active both in her profession and in domestic affairs, and always very courteous. They had no children. Although he did not speak Malay very well, still, owing to his earnestness of purpose, Lidju was of considerable assistance to me. The kampong consists of several long houses of the usual Dayak style, lying in a row and following the river course, but here they were separated into two groups with a brook winding its way to the river between them. Very large drums, nearly four metres long, hung on the wall of the galleries, six in one house, with the head somewhat higher than the other end. This instrument, slightly conical in shape, is formed from a log of fine-grained wood, light in colour, with a cover made from wild ox hide. An especially constructed iron tool driven by blows from a small club is used to hollow out the log, and the drum is usually completed in a single night, many men taking turns. In one part of the house lying furthest west lived Dayaks called Oma-Palo, who were reported to have been in this tribe a hundred years. They occupied "eight doors," while further on, in quarters comprising "five doors," dwelt Oma-Tepe, more recent arrivals; and both clans have married Oma-Suling women.
