INSTINCT OF TEEES.

moon; but such was the confusion produced 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 Cliihombo, a feeder of the Kasai. Those who know the 
difficulties of taking altitudes, times, and distances, and com¬ 
mitting all of them to paper, will sympathise with me in this 
and many similar instances. Whilst 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 
bffd 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 anything 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 neighbour 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 inva¬ 
riably 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 tlmead 
of a screw, rather than in any other. On the one bank of the 
Chihune they appeared to a person standing opposite them to
