"The various devices recommended in the books of one's childhood, and, it may be added, in learned books as well, whereby the traveller is enabled to recover a lost trail or regain the right direction, are here of no avail. For instance, moss does not grow more on one side of a tree-trunk than on the other; trees do not lean away from the prevailing wind; nor is the position of the sun a guide, for it is seldom visible. In fact, the traveller has nothing to rely upon but the compass or a local guide, and even the latter is often at fault. Hopeless indeed does the outlook appear when the wanderer, hedged in by a wall of scrub and creeper which limits his vision to a distance of ten or twelve yards, realizes that he has lost his bearings; when the vastness of the forest seems to press upon him, and there is no sound to be heard but the drip, drip of the water-laden trees and the bubbling of the stinking bog underfoot. His only chance of escape is to find a stream, and follow it down till it joins a main river." The first big episode was the discovery of the Pygmies who lived in the foothills, and were assiduously hunted by the forest tribes. The average height of these little men was 4 feet 7 inches, and Captain Rawling penetrated to their village in a clearing above the head waters of the Mimika. The Mimika source was reached, but led them nowhere, and they fared no better with another small stream to the west, called the Kapare. Then by accident a secret native path was discovered running eastward--a mere tunnel in the matted forest. By this route they were able to reach a parallel river, called the Tuaba, which was a tributary of the larger Kamura. From a village called Ibo as a centre, the expedition made various casts east and north, but found it impossible to get near the skirts of the hills. Captain Rawling returned to the coast and made excursions along the eastern shore, but found no adjacent river mouth which promised better. By this time it was June, and the floods began with such vigour that practically the whole country between the mountains and the sea was under water. When the floods ebbed, a resolute attempt was made to push east from Ibo, and with a good deal of trouble another parallel stream was reached, called the Wataikwa. The party founded a camp there, and explored the upper waters of that stream. Travelling was extremely difficult, because the only decent road was the river bed, and this route was promptly made impossible by a new spate. The travellers had to face the fact that the farther they went eastward the greater became the labour of carrying supplies, for their base camp remained on the Mimika.
