It would not be a matter of much difficulty to widen the narrow places between the entrance to the cavern and the broader clefts in the interior, so that a miniature boat might be introduced; it would at least make it possible to penetrate to the end of the passages, and might probably be the means of discovering loftier and more spacious grottoes. To me it appeared that away from the river the passages were mere rifts, but that closer to the river they were invariably wider, thus confirming the impression that the water in making its way along them had gradually washed out for itself a larger outlet.
We were not in the caves very long, but found them thickly tenanted by bats, that kept on following us up to the very entrance. Our guides held the fluttering creatures in such abhorrence that nothing would induce them to touch them; they were accordingly much surprised when I captured two of them as an addition to my collection of mammalia, and as a memorial of my visit to the wonderful grottoes.
Wonderfontein is one of those places in South Africa where an explorer may advantageously, spend a considerable time, ever finding an ample reward for his labours; the animal, the vegetable, and the mineral world are all well worthy of his best investigation. My own visit on this occasion was necessarily limited to three days, so that I could obtain nothing beyond a cursory glance at the neighbourhood.
