He whispered, "We'll worry about that when we get to the top."
He began to climb again. With one shoulder wedged into the crack, he was able to push and drag himself upward an inch at a time, paying for it with skin from his knuckles and bare knees.
Gradually the crack continued to open wider, until it became a full chimney and he could get his whole body into it and double one leg under him to propel himself upward more swiftly At the op the chimney had eroded and crumbled. One side wall of the chimney had broken away, but it had left a narrow buttress with a flat top. Sean was able to transfer his weight across the chimney utntil he was standing on this precarious pinnacle.
The top of the cliff was still ten feet above his head. When he reached up to the full stretch of his arms, standing on the tips of Ms toes, the ledge was stiff just out of reach. The chimney wall had broken away clearly, leaving a smooth, almost polished surface without even the minutest hold or purchase. A good, safe climber moved from hold to hold with never a single moment when he was totally insecure. In a situation such as this that hypothetical climber would have driven an iron piton into the rock to give him the hold he needed.
"Look, Mummy, no pitons," Sean said grimly. "We'll have to jump for it." He would have only one chance at it. If he missed his hold on the ledge once he had launched himself, the next stop would be the base of the cliff.
He set both feet firmly and sank down at the knees, but he was so cramped on the tip of the buttress that he could not get low enough before his face touched the rock and his backside stuck far out over the drop. He took a breath and used both arms and legs to propel himself straight upward. It was an awkward, hampered jump, but he got high enough to hook both hands over the edge.
For a moment they began to slide back, then his fingers gripped and held.
He kicked both legs and drew himself upward by the main strength of his arms. His chin came level with the ledge, and in the moonlight he saw in front of him a false crest, simply another ledge below the true top of the cliff.
The ledge was obviously occupied by a colony of rock hyrax.
The stink of their droppings, sharp and ammoniac al filled Sean's lungs as he gasped from the effort of holding himself. The hyrax is a plump, fluffy animal. Although it is only the size of a rabbit, it is a remote relative of the elephant and as endearing in appearance as an infant's soft toy. These hyrax were deep in their rocky burrows now, and the ledge seemed deserted. Sean hoisted himself up smoothly and hooked one elbow over the edge; he kicked again, gathering himself for the final effort. Then he froze.
The silence of the night was cut by a loud high-pitched hiss, like the leaking valve of a truck tire. In the moonlight what he had taken for a pile of rock lying directly in front of his face altered shape, seeming to melt and flow. In an instant Sean realized it was a snake. Only one of the adders would hiss as loudly, and only one adder was that large.
It was coiled upon itself, loop after loop of its thick scaly body glistening softly, and as it cocked its neck into a menacing "S" the moon and winked at him shape, its eye caught the light of sardonically.
The huge flat head was the distinctive spade shape of the ga boon adder, the largest of all the adders and one of the deadliest of all of Africa's venomous snakes.
Sean could drop back and try to regain his stance on the narrow pinnacle of rock, but that was a slim chance and if he missed it, he e ul would plunge down the cliff face. A much better chanc would be to try and brave it out.
He hung with legs free, trying to control his breathing, staring in horror at the loathgbme creature- It was cocked to strike less than two feet from 4is face, and he knew it could lunge out almost its full body length," seven feet or more The slightest movement would trigger it.
He hung on his arms, every muscle of his body rigid, staring at the adder, trying to dominate it by the force of his will. The seconds drew out as slowly as spilled molasses, and he thought he detected the first relaxation in the taut "S" of its neck.
At that moment his left hand slipped, his fingernails rasped on the rock, and the adder struck with the force Of a blacksmith's hammer.
Sean rolled his head to the side like a boxer avoiding a punch.
The adder's cold, scaly nose jarred against his jawbone and there was a fierce tug against his neck and shoulder, so powerful it jerked one hand loose from its hold on the rock and spun him half around. He was sideways to the ledge, holding on with only his left arm.
He knew the adder had hooked its fangs into his shoulder or the side of his throat, and he expected the exquisite fire of its venom to kindle in his flesh. The serpent was locked onto him, dangling down the front of his body, thick as a salami sausage; it squirmed and thrashed, hissing explosively in his ear. The cold touch of its slippery scales brushed against his bare flesh.
Sean almost screamed with the sheer horror of it. The adder's weight threw him about as it lashed from side to side, and its loud hisses deafened him. He felt his single-handed grip on the ledge slipping, but the prospect of the drop below him was suddenly insignificant when compared to this foul creature fastened to his neck.
He felt an icy spray of liquid on the side of his throat and his jaw; it dribbled down the opening of his bush jacket, and with a rush of relief he knew the adder had missed his throat and fastened onto the collar of his jacket. Its fangs were fully two inches long and viciously curved, designed to penetrate and hang on to its prey.
Hooked into the khaki cotton material of his collar, its violent struggles were forcing the venom out of the hollow bony needles, and it was squirting onto his throat and bare skin.
The realization that the fangs had not penetrated his flesh rallied him, firmed his grip on the ledge, and arrested his slow slide into the drop. His right hand was still free. He reached up and seized the adder's neck just at the back of its flat diamond-shaped head.
