My eye was caught by a quivering twig; on it was a chameleon. The reptile was nearly nine inches long. His colour was brown, of a shade exactly the same as that of the twig. He moved forward with slow, hesitating steps; he paced like an amateur on the tight-rope, as though afraid of falling. His swivel eye-cases, each with a tiny, diamond-bright speck in the centre, moved about independently of each other. One was focussed on a little green insect waving its antennae on a leaf six inches in front of him; the other was carefully trained backwards over his left shoulder at me. Flick--and his tongue shot out and in so rapidly that the eye could hardly follow its motion. But the insect was no longer on the leaf, and the chameleon was munching something with solemn enjoyment. When night fell he would climb to the top of a strong, dry twig, roll and tuck himself into the shape of a pear, with his head in the centre of the bulge. Then he would change his hue to white and open his mouth, which was bright orange internally. The night-flying lepidoptera would take him for a white, yellow-centred flower, and pop in, seeking nectar. But they would not pop out again. And the greatest wonder of all,--I bent down to examine a gazania; its inch-long golden rays expanded like a wheel of perfect symmetry. Just where the ray bent over the edge of the green, fleshy cup in which the myriad florets were nested, was a small, dark spot. I brought a simple magnifying glass to bear on this,--and what did I see? A labyrinthine crater of many-coloured fire opened. Curve melted and mingled into reluctant curve, zone into rainbow zone, until the plummet of vision was lost in the radiant abyss. I lifted the flower gently; its texture was thinner than the thinnest paper; beneath it was the desert sand. It had hardly any material thickness, yet infinity lay in its depths. I sought for a gazania of another species and found its petals eyed like the peacock's tail. Yet another,--it shewed the rose-ardours of dawn contending with the purple of a sea on whose surface night still brooded. Every species had its own colour-scheme--its maze of splendour more intricate than the labyrinth of King Minos.
