I scaled and scrambled over and crawled upon huge rocks, peered into gloomy crevices with daylight edges fringed with ferns and orchids, squeezed through narrow tunnels, and groped in dark recesses without finding any evidence of prehistoric art. Blacks do not care to venture into places where twilight always reigns, though they are curious to learn the experiences and sensations of other explorers of the gloom. At last, however, patience was rewarded, and beneath a great granite rock, which on three previous excursions had been overlooked, the paintings were discovered. In their execution the artist must have lain on his back, for the "cave" does not permit one to sit upright in it, except towards the wide and expansive front, and the subjects are on the ceiling, which is fairly flat. The floor, thick with a fine brown dust mingled with shining specks of decomposed granite, and dimpled with hundreds of pitfalls of the ant-lion, slopes upward. It is cool, and a dry, secure spot. Not even the torrential rains of many decades of wet seasons have damped the floor. One feels as though he were disturbing the dust of ages; when sitting back to admire the decorated ceiling, he necessarily imprints patterns which are the replicas of those made by flesh and bone long since numbered among the anonymous dead. The sea laves the hot rocks 600 feet below, and booms and gobbles in the cool crevices; but up here the outlook is obscured by rocks and giant trees, and an artistic soul, longing for some method of expression, might serenely gratify itself in accordance with its lights--crude though they were. Here, at the entrance, lie a couple of charred sticks, significant of the last fire of the artist, which smouldered out perhaps half a century ago. On the very doorstep is a disc of pearl-shell, the discarded beginning of a fish-hook. These relics give to the scene a pathetic interest. As I looked at them ponderingly, a frog far in the back of the cave gave a discordant, echoing croak, which started the sulky and suspicious black boy who attended me into an abrupt exclamation of semi-fright; while a scrub fowl, scratching for its living overhead, dislodged a chip of granite which went clicking down the rocks. "Tom," at the instant, felt that the spirit of the departed was manifesting, in the hollow tones of a frog and the activity of a bird, resentment at the intrusion of his haunts, and was warning us to begone. But we had come far on a toilsome errand, and were not to be scared away by trifles, though a transient feeling of reluctance to disturb the solemnity of the studio could not be withheld.
