The Dyaks are also very truthful. So disgraceful indeed do the Dyaks consider the deceiving of others by an untruth that such conduct is handed down to posterity by a curious custom. They heap up a pile of the branches of trees in memory of the man who has uttered a great lie, so that future generations may know of his wickedness and take warning from it. The persons deceived start the _tugong bula_—“the liar’s mound”—by heaping up a large number of branches in some conspicuous spot by the side of the path from one village to another. Every passer-by contributes to it, and at the same time curses the man in memory of whom it is. The Dyaks consider the adding to any _tugong bula_ they may pass a sacred duty, the omission of which will meet with supernatural punishment, and so, however pressed for time a Dyak may be, he stops to throw on the pile some branches or twigs. A few branches, a few dry twigs and leaves—that is what the _tugong bula_ is at first. But day by day it increases in size. Every passer-by adds something to it, and in a few years’ time it becomes an imposing memorial of one who was a liar. Once started, there seems to be no means of destroying a _tugong bula_. There used to be one by the side of the path between Seratok and Sebetan. As the branches and twigs that composed it often came over the path, on a hot day in the dry weather I have more than once applied a match to it and burnt it down. In a very short time a new heap of branches and twigs was piled on the ashes of the old _tugong bula_. It has often been remarked by Dyaks that any other punishment would, if a man had his choice, be much preferred to having a _tugong bula_ put up in his memory. Other punishments are soon forgotten, but this remains as a testimony to a man’s untruthfulness for succeeding generations to witness, and is a standing disgrace to his children’s children. Believing, as the Dyaks do, in the efficacy of curses, it is easy to understand how a Dyak would dread the accumulation of curses which would necessarily accompany the formation of a _tugong bula_. The Dyaks are very hospitable. They are always ready to receive and entertain strangers. A man travelling on foot through the Dyak country need never trouble about food. He would be fed at the Dyak houses he passed on his journey, as part of their crops is reserved to feed visitors. When the family meal is ready, visitors are invited to partake of it. If many visitors come to a house at the same time, some have their meal with one family and some with another.
