in my mind by the state of my body, that I could scarcely manage, after some hours’ trial, to get a lunar observation in which I could repose confidence.  The Chihune flows into the Longe, and that into the Chihombo, a feeder of the Kasai.  Those who know the difficulties of taking altitudes, times, and distances, and committing all of them to paper, will sympathize with me in this and many similar instances.  While at Chihune, the men of a village brought wax for sale, and, on finding that we wished honey, went off and soon brought a hive.  All the bees in the country are in possession of the natives, for they place hives sufficient for them all.  After having ascertained this, we never attended the call of the honey-guide, for we were sure it would only lead us to a hive which we had no right to touch.  The bird continues its habit of inviting attention to the honey, though its services in this district are never actually needed.  My Makololo lamented that they never knew before that wax could be sold for any thing of value.

As we traverse a succession of open lawns and deep forests, it is interesting to observe something like instinct developed even in trees.  One which, when cut, emits a milky juice, if met with on the open lawns, grows as an ordinary umbrageous tree, and shows no disposition to be a climber; when planted in a forest it still takes the same form, then sends out a climbing branch, which twines round another tree until it rises thirty or forty feet, or to the level of the other trees, and there spreads out a second crown where it can enjoy a fair share of the sun’s rays.  In parts of the forest still more dense than this, it assumes the form of a climber only, and at once avails itself of the assistance of a tall neighbor by winding vigorously round it, without attempting to form a lower head.  It does not succeed so well as parasites proper, but where forced to contend for space it may be mistaken for one which is invariably a climber.  The paths here were very narrow and very much encumbered with gigantic creepers, often as thick as a man’s leg.  There must be some reason why they prefer, in some districts, to go up trees in the common form of the thread of a screw rather than in any other.  On the one bank of the Chihune they appeared to a person standing opposite them to wind up from left to right, on the other bank from right to left.  I imagined this was owing to the sun being at one season of the year on their north and at another on their south.  But on the Leeambye I observed creepers winding up on opposite sides of the same reed, and making a figure like the lacings of a sandal.
