By this time the ferry had arrived, and Ben and Agustine were arguing hotly with its aged occupant. Instead of taking us straight across the river, they wanted him to paddle us about half a mile upstream to a large sandbank. This would save us having to walk about a mile along the bank to reach the path that led to the forest. The old man appeared to be singularly obstinate about the proposal.
‘What’s the matter with him, Ben?’ I inquired.
‘Eh! Dis na foolish man, sah,’ said Ben, turning to me in exasperation, ‘’e no agree for take us for up de river.’
‘Why you no agree, my friend?’ I asked the old man. ‘If you go take us I go pay you more money and I go dash you.’
‘Masa,’ said the old man firmly, ‘dis na my boat, and if I go lose um I no fit catch money again … I no get chop for my belly … I no get one-one penny.’
‘But how you go lose you boat?’ I asked in amazement, for I knew this strip of river and there were no rapids or bad currents along it.
‘Ipopo, Masa,’ explained the old man.
I stared at the ferryman, wondering what on earth he was talking about. Was Ipopo perhaps some powerful local juju I had not come across before?
‘Dis Ipopo,’ I asked soothingly, ‘which side ’e live?’
‘Wah! Masa never see um?’ asked the old man in astonishment. ‘’E dere dere for water close to D.O.’s house … ’e big like so-so motor … ’e de holla … ’e de get power too much.’
‘What’s he talking about?’ asked Bob in bewilderment.
And suddenly it dawned on me. ‘He’s talking about the hippo herd in the river below the D.O.’s house,’ I explained, ‘but it’s such a novel abbreviation of the word that he had me foxed for a moment.’
‘Does he think they’re dangerous?’
‘Apparently, though I can’t think why. They were perfectly placid last time I was here.’
‘Well, I hope they’re still placid,’ said Bob.
I turned to the old man again. ‘Listen, my friend. If you go take us for up dis water, I go pay you six shilling and I go dash you cigarette, eh? And if sometime dis ipopo go damage dis your boat I go pay for new one, you hear?’
‘I hear, sah.’
‘You agree?’
‘I agree, sah,’ said the old man, avarice struggling with caution. We progressed slowly upstream, squatting in half an inch of water in the belly of the canoe.
‘I suppose they can’t really be dangerous,’ said Bob casually, trailing his hand nonchalantly in the water.
‘When I was here last I used to go up to within thirty feet of them in a canoe and take photographs,’ I said.
‘Dis ipopo get strong head now, sah,’ said Ben tactlessly. ‘Two months pass dey kill three men and break two boats.’
‘That’s a comforting thought,’ said Bob.
Ahead of us the brown waters were broken in many places by rocks. At any other time they would have looked exactly like rocks but now each one looked exactly like the head of a hippo, a cunning, maniacal hippo, lurking in the dark waters, awaiting our approach. Ben, presumably remembering his tale of daring with the bush-cow, attempted to whistle, but it was a feeble effort, and I noticed that he scanned the waters ahead anxiously. After all, a hippo that has developed the habit of attacking canoes gets a taste for it, like a man-eating tiger, and will go out of his way to be unpleasant, apparently regarding it as a sport. I was not feeling in the mood for gambolling in twenty feet of murky water with half a ton of sadistic hippo.
The old man, I noticed, was keeping our craft well into the bank, twisting and turning so that we were, as far as possible, always in shallow water. The cliff here was steep, but well supplied with footholds in case of emergency, for the rocks lay folded in great layers like untidy piles of fossilized magazines, overgrown with greenery. The trees that grew on top of the cliffs spread their branches well out over the water, so that we travelled in a series of fish-like jerks up a tunnel of shade, startling the occasional kingfisher that whizzed across our bows like a vivid blue shooting-star, or a black-and-white wattled plover that flapped away upstream, tittering imbecilically to itself, with its feet grazing the water, and long yellow wattles flapping absurdly on each side of its beak.
Gradually we rounded the bend of the river, and there, about three hundred yards ahead of us on the opposite shore, lay the white bulk of the sandbank, frilled with ripples. The old man gave a grunt of relief at the sight, and started to paddle more swiftly.
‘Nearly there,’ I said gaily, ‘and not a hippo in sight.’
The words were hardly out of my mouth when a rock we were passing some fifteen feet away suddenly rose out of the water and gazed at us with bulbous astonished eyes, snorting out two slender fountains of spray, like a miniature whale.
Fortunately, our gallant crew resisted the impulse to leap out of the canoe en masse and swim for the bank. The old man drew in his breath with a sharp hiss, and dug his paddle deep into the water, so that the canoe pulled up short in a swirl and clop of bubbles. Then we sat and stared at the hippo, and the hippo sat and stared at us. Of the two, the hippo seemed the more astonished. The chubby, pink-grey face floated on the surface of the water like a disembodied head at a séance. The great eyes stared at us with the innocent appraisal of a baby. The ears flicked back and forth, as if waving to us. The hippo sighed deeply and moved a few feet nearer, still looking at us with wide-eyed innocence. Then, suddenly, Agustine let out a shrill whoop that made us all jump and nearly upset the canoe. We shushed him furiously, while the hippo continued its scrutiny of us unabashed.
‘No de fear,’ said Agustine in a loud voice, ‘na woman.’
He seized the paddle from the old man’s reluctant grasp, and proceeded to beat on the water with the blade, sending up a shower of spray. The hippo opened its mouth in a gigantic yawn to display a length of tooth that had to be seen to be believed. Then, suddenly, and with apparently no muscular effort, the great head sank beneath the surface. There was a moment’s pause, during which we were all convinced that the beast was ploughing through the water somewhere directly beneath us, then the head rose to the surface again, this time, to our relief, about twenty yards up-river. It snorted out two more jets of spray, waggled its ears seductively and sank again, only to reappear in a moment or so still farther upstream. The old man grunted and retrieved his paddle from Agustine.
‘Agustine, why you do dat foolish ting?’ I asked in what I hoped was a steady and trenchant tone of voice.
‘Sah, dat ipopo no be man … na woman dat,’ Agustine explained, hurt by my lack of faith in him.
