I hope that during my next journey I may be able to pierce more deeply into the psychology of the Papuans, and it may be that, with greater familiarity, they will communicate more of what they know; for it appears improbable that they should be as destitute as they seem of legend or myth. [Illustration: SMOKING THE BAU-BAU. This curious pipe is made of a length of bamboo closed at each end. Into a small hole at one end is inserted a small green leaf rolled like a grocer’s paper bag. In this the lighted tobacco is placed. The smoker then reverses the tube, and sucks in the smoke until the bamboo is filled. He now takes out the tobacco and inhales a long whiff. The operation is repeated as long as the tobacco lasts. ] Over the “Bau-bau,” or social pipe, I trust there may be some discoveries in store for me. The Papuan pipe is itself a most interesting instrument, not only in its everyday use, but in its construction and in the method of smoking. It is made of one joint of bamboo, closed at both ends by the natural section of the bamboo. In the side of the cylinder near one end they drill a hole by applying a piece of hard wood made red-hot. They press the red-hot wood to the bamboo, and blow it to incandescence, repeating the operation until a hole is pierced. They next knock a hole in the opposite end of the bamboo, so as to admit a current of air. The red-hot wood is now applied again to the original hole, and they blow through the hole knocked in the opposite end until the small hole in the side is gradually enlarged. The “Bau-bau” is now complete, except for its ornamentation. Elaborate patterns are scratched on the hard enamel of the bamboo with glass, a knife, a stone, or red-hot wood, and the speed with which this decoration is accomplished is extraordinary. In the accompanying illustration I show some of the prevailing patterns. On the march our men would cut a bamboo, and on reaching camp would borrow some suitable tool from us, and make a pipe in a very short time. They were sufficiently accomplished smokers, however, to like an old “Bau-bau” best, and gave the reason, which will be appreciated by every smoker, that tobacco is not good in a new one.
