It is not a forest country. Strange clumps of trees grow on the tops of the hills, which mark the ancient plateau level, but the rich soil beside the streams and in the snug valleys is generally well wooded. The vegetation presents an altogether tropical appearance, the bracken in the glades is the only thing home-like. Rich creepers drape the trees, beautiful palms lend their rare grace, and in their seasons an endless succession of beautiful flowers, from huge arums to a tiny crucifer of the richest scarlet, bright creepers, pure white stephanotis-like blossoms, rich lilies, and many other gorgeous plants, and bright berries, not in such wild, packed profusion that the eye is bewildered with a blaze of beauty, but here and there with sufficient interval to permit the due appreciation of their several lovelinesses. The beauty of the leaf-forms is alone a pleasure; while the tints from the darkest green to soft yellow, delicate pink, bronze, chocolate, and bright crimson are mysteries of colour. On the rocky stream banks and on the palm stems are graceful ferns, while the _lycopodium_ climbs the bushes, mingled with the beautiful _selaginella_. The scenery of the country is described in an unequalled manner by Mr. H. H. Johnston in his book, _The River Congo_. Himself an accomplished artist, he describes as only an artist can. The vegetation suffers from the annual grass fires, which sweep the country. As soon as the dry season has well set in (June) the burning commences; in some parts it does not become general until August. The grass is fired sometimes on a small scale by the children, that they may hunt their rats, but the great fires occur when the natives of a district combine for a grand hunt. For days the fire steadily sweeps along, the game flee before it, hawks wheel above the line of fire, catching the grasshoppers that seek to avoid the flames, while smaller birds catch the lesser insects. The internodes of the burning grass explode with a report like that of a pistol, and can be heard distinctly a mile distant. Women and children follow on the line to dig out the rats; and in the holes may be found rats, mice, snakes, and lizards, seeking common protection from a common danger. At night the horizon is lit up by the zigzag lines of fire, and in the daytime are seen the thick columns of smoke slowly advancing, and filling the air with a dull haze, which limits the horizon to ten or fifteen miles.
