What with making light shelters against sun and rain, in Malay called atap, usually erected for long journeys, the placing of split bamboo sticks in the bottom of my prahu, and with the Penihings evidently unaccustomed to such work, it was eight o'clock before the start was made. Pani, a small tributary forming the boundary between the Penihings and the Kayans, was soon left behind and two hours later we passed Long Blu, the great Kayan kampong. The weather was superb and the current carried us swiftly along. The great Mahakam River presented several fine, extensive views, with hills on either side, thick white clouds moving slowly over the blue sky. As soon as we entered the country of the Oma-Suling it was pleasant to observe that the humble cottages of the ladangs had finely carved wooden ornaments standing out from each gable.

We arrived at Long Pahangei (h pronounced as Spanish jota) early in the afternoon. Gongs were sounding, but very few people were there, and no visitors at all, although this was the first day of the feast. This is a large kampong lying at the mouth of a tributary of the same name, and is the residence of a native district kapala. After I had searched everywhere for a quiet spot he showed me a location in a clump of jungle along the river bank which, when cleared, made a suitable place for my tent. Our Penihings were all eager to help, some clearing the jungle, others bringing up the goods as well as cutting poles and bamboo sticks. Evidently they enjoyed the work, pitching into it with much gusto and interest. The result was a nice though limited camping place on a narrow ridge, and I gave each man one stick of tobacco as extra payment.

During our stay here much rain fell in steady downpours lasting a night or half a day. As the same condition existed higher up the river, at times the water rose menacingly near my tent, and for one night I had to move away. But rain in these tropics is never merciless, it seems to me. Back from the coast there is seldom any wind, and in the knowledge that at any time the clouds may give place to brilliant sunshine, it is not at all depressing. Of course it is better to avoid getting wet through, but when this occurs little concern is felt, because one's clothing dries so quickly.

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.

The purpose of the great feast that filled everybody's thoughts is to obtain many children, a plentiful harvest, good health, many pigs, and much fruit. A prominent Dayak said to me: "If we did not have this feast there would not be many children; the paddi would not ripen well, or would fail; wild beasts would eat the fowls, and there would be no bananas or other fruits." The first four days are chiefly taken up with preparations, the festival occurring on the fifth and sixth days. A place of worship adjoining the front of the easternmost house was being constructed, with a floor high above ground on a level with the gallery, with which it was connected by a couple of planks for a bridge. Although flimsily built, the structure was abundantly strong to support the combined weight of the eight female blians who at times performed therein. The hut, which was profusely decorated with long, hanging wood shavings, is called dangei and is an important adjunct of the feast, to which the same name is sometimes given. Ordinary people are not allowed to enter, though they may ascend the ladder, giving access to the gallery, in close proximity to the sanctuary.

Prior to the fifth day a progressive scale is observed in regard to food regulations, and after the sixth, when the festive high mark is reached, there is a corresponding decrease to normal. Only a little boiled rice is eaten the first day, but on the second, third, and fourth, rations are gradually increased by limited additions of toasted rice. The fifth and sixth days give occasion for indulgence in much rice and pork, the quantity being reduced on the seventh, when the remaining pork is finished. On the eighth and ninth days the regulations permit only boiled and toasted rice. Not much food remains on the tenth, when the menu reverts to boiled rice exclusively. Some kinds of fish may be eaten during the ten-day period, while others are prohibited.

It was interesting to observe what an important part the female blians or priest-doctors played at the festival. They were much in evidence and managed the ceremonies. The men of the profession kept in the background and hardly one was seen. During the feast they abstain from bathing for eight days, do not eat the meat of wild babi, nor salt; and continence is the rule. Every day of the festival, morning, afternoon, and evening, a service is performed for imparting health and strength, called melah, of which the children appear to be the chief beneficiaries. Mothers bring babes in cradles on their backs, as well as their larger children. The blian, who must be female, seizing the mother's right hand with her left, repeatedly passes the blade of a big knife up her arm. The child in the cradle also stretches out its right arm to receive treatment, while other children and women place their right hands on the hand and arm of the first woman, five to ten individuals thus simultaneously receiving the passes which the blian dispenses from left to right. She accompanies the ceremony with murmured expressions suggesting removal from the body of all that is evil, with exhortations to improvement, etc.

This service concluded, a man standing in the background holding a shield with the inside uppermost, advances to the side of the mother and places it horizontally under the cradle, where it is rapidly moved forward and backward. Some of the men also presented themselves for treatment after the manner above described, and although the melah performance is usually reserved for this great feast, it may be employed by the blian for nightly service in curing disease.

This was followed by a dance of the blians present, nine or ten in number, to the accompaniment of four gongs and one drum. They moved in single file, most of them making two steps and a slight turn to left, two steps and a slight turn to right, while others moved straight on. In this way they described a drawn-out circle, approaching an ellipse, sixteen times. After the dancing those who took part in the ceremonies ate toasted rice. Each day of the feast in the afternoon food was given to antoh by blians and girl pupils. Boiled rice, a small quantity of salt, some dried fish, and boiled fowl were wrapped in pieces of banana leaves, and two such small parcels were offered on each occasion.
