Of the rest of our journey to the water’s edge there is nothing to tell, except that notwithstanding our loads, we found it easier to walk down that steep mountain side than it had been to ascend the same. Still our progress was but slow, and when at length we reached the burying-place only about an hour remained to sunset. There we sat down to rest and eat, also to discuss the situation.

What was to be done? The arm of stagnant water lay near to us, but we had no boat with which to cross to the further shore. And what was that shore? A cave where a creature who seemed to be but half-human, sat watching like a spider in its web. Do not let it be supposed that this question of escape had been absent from our minds. On the contrary, we had even thought of trying to drag the canoe in which we crossed to and from the island of the Flower through the forest. The idea was abandoned, however, because we found that being hollowed from a single log with a bottom four or five inches thick, it was impossible for us to carry it so much as fifty yards. What then could we do without a boat? Swimming seemed to be out of the question because of the crocodiles. Also on inquiry I discovered that of the whole party Stephen and I alone could swim. Further there was no wood of which to make a raft.

I called to Hans and leaving the rest in the graveyard where we knew that they were safe, we went down to the edge of the water to study the situation, being careful to keep ourselves hidden behind the reeds and bushes of the mangrove tribe with which it was fringed. Not that there was much fear of our being seen, for the day, which had been very hot, was closing in and a great storm, heralded by black and bellying clouds, was gathering fast, conditions which must render us practically invisible at a distance.

We looked at the dark, slimy water—also at the crocodiles which sat upon its edge in dozens waiting, eternally waiting, for what, I wondered. We looked at the sheer opposing cliff, but save where a black hole marked the cave mouth, far as the eye could see, the water came up against it, as that of a moat does against the wall of a castle. Obviously, therefore, the only line of escape ran through this cave, for, as I have explained, the channel by which I presume Babemba reached the open lake, was now impracticable. Lastly, we searched to see if there was any fallen log upon which we could possibly propel ourselves to the other side, and found—nothing that could be made to serve, no, nor, as I have said, any dry reeds or brushwood out of which we might fashion a raft.

“Unless we can get a boat, here we must stay,” I remarked to Hans, who was seated with me behind a screen of rushes at the water’s edge.

He made no answer, and as I thought, in a sort of subconscious way, I engaged myself in watching a certain tragedy of the insect world. Between two stout reeds a forest spider of the very largest sort had spun a web as big as a lady’s open parasol. There in the midst of this web of which the bottom strands almost touched the water, sat the spider waiting for its prey, as the crocodiles were waiting on the banks, as the great ape had waited for the Kalubis, as Death waits for Life, as the Motombo was waiting for God knows what.

It rather resembled the Motombo in his cave, did that huge, black spider with just a little patch of white upon its head, or so I thought fancifully enough. Then came the tragedy. A great, white moth of the Hawk species began to dart to and fro between the reeds, and presently struck the web on its lower side some three inches above the water. Like a flash that spider was upon it. It embraced the victim with its long legs to still its tremendous battlings. Next, descending below, it began to make the body fast, when something happened. From the still surface of the water beneath poked up the mouth of a very large fish which quite quietly closed upon the spider and sank again into the depths, taking with it a portion of the web and thereby setting the big moth free. With a struggle it loosed itself, fell on to a piece of wood and floated away, apparently little the worse for the encounter.

“Did you see that, Baas?” said Hans, pointing to the broken and empty web. “While you were thinking, I was praying to your reverend father the Predikant, who taught me how to do it, and he has sent us a sign from the Place of Fire.”

Even then I could not help laughing to myself as I pictured what my dear father’s face would be like if he were able to hear his convert’s remarks. An analysis of Hans’s religious views would be really interesting, and I only regret that I never made one. But sticking to business I merely asked:

“What sign?”
