"Come on," Ralph grunted at the man on his arm, and suddenly the earth beneath their feet lunged the other way, throwing them forward towards the rim of the pit and safety.

They went forward with a rush, the driver clutching at Ralph's shoulder for support. A dozen paces to go to firm ground, and Ralph did not look back again. The hideous sounds from the pit were unnerving, and he sensed that another glimpse of that onrushing wave of collapsing earth might paralyse his own legs.

"Come on," he gasped. "We'll make it, almost there.

Come on!" And as he said it the earth opened in front of their feet as though from a giant's axe stroke. It opened with a smacking sound, as of kissing lips, and the mouth of it was sheer, eighty feet deep and three feet across, but in the brief seconds that they tottered on the edge it gaped wider, six feet, eight feet, and the causeway tilted sideways, the final convulsion.

Jump!" said Ralph. "Jump for it, man." And he shoved the driver at it, forcing him at that frightful crack that seemed to split the earth to its very core.

The man stumbled off balance, his arms waving wildly for control, and then he made a clumsy scrambling leap out over the drop. The torn oilskins tangled with his limbs and fluttered about his head. He hit the far lip of the crack with his chest, his legs hanging into the drop and kicking hopelessly, and clawed at the muddy lip. But there was no purchase and inexorably he began to slide backwards.

Ralph knew there was no chance of making a run-up to the jump. He had to take it from a standstill, and it was gaping wider with every second, ten feet or more now, and the quivering bank of collapsing earth was an unstable platform.

He sank on one knee, steadied himself with a clenched fist against the earth, and then straightened his legs and body in a sudden burst of energy like a released coilspring, jumping high because the causeway had already sagged below the level of the rim.

The power of that leap surprised even Ralph; he cleared the driver's wriggling body and landed deep, on firm and rock-steady ground, stumbled with his own forward impetus and then ran on half a dozen paces.

Behind him the driver wailed and slid back a few inches, and around his spread fingers opened a mesh of smaller cracks, running parallel to the gaping sheer line.

Ralph spun and ran back. He threw himself flat and reached for the driver's wrist. It was greasy with mud, slippery as a freshly netted trout, and he knew he could not hold him for long.

Over the driver's head Ralph stared down into the diggings. He watched the final collapse of the causeway, a massive rush of earth, some of it liquid mud, mixed with huge chunks of compacted gravel that ground together like the jaws of some mindless monster, crushing and smothering men and animals between them.

The entire number 6 Roadway was gone, and across the floor of the pit, deep dark cracks spread out like a grotesque spider's web.

In the bottom of the diggings the figures of men seemed frail and insectlike, their cries feeble and without consequence, their pathetic scurrying without purpose.

Ralph suddenly recognized his father. He alone was standing firm, his head thrown back, and even across that dizzy space Ralph could feel the strength of his gaze.

"Hold on, boy!" Zouga's voice carried faintly above the pandemonium. "They're coming. Hold on!"

But under Ralph's belly the earth whispered and shrugged impatiently and the driver's weight pulled him another inch towards the drop.

"Hold on, Ralph!"

Across that aching breathless space Zouga was reaching out with both hands, a gesture that was more eloquent than any words, a gesture of suffering and helpless love.

Then suddenly Ralph felt rough hands seize the ankles of his muddy boots, the shouts of many men behind him, the rasp of a hairy manila rope against his cheek, the noose dangling in front of his face, and with a huge surge of relief he saw the dangling driver thrust his free arm through the noose and saw it drawn tight.

Ralph could let the muddy wrist slip from his grip, and he crawled back from the edge.

He looked down at his father. It was too far for either of them to see the expression on each other's face.

For a moment longer Zouga stared up at him. Then he turned away abruptly, his stride businesslike, his gestures imperative as he ordered his Matabele forward to the rescue work.

The rescue went on all that day. For once every digger on New Rush was united by a common purpose.

The Diggers" Committee closed the workings and ordered every man out of the unaffected areas. The five other roadways that had not collapsed were declared out of bounds to all traffic and they stood high and menacing in the silver clouds of drifting rain.

On the churned and collapsed remnants of number 6 Roadway the -rescuers swarmed. These were the men who had been trapped on the floor by the severed ladderworks and the fallen system of gantries.

There were no members of the Committee in the number 6 area, and Zouga Ballantyne with his natural air of authority was quickly accepted as the leader. He had marked the position of the gravel carts and drivers on the roadway at the moment of the cave-in, and he split the available men into gangs and set them to digging where be guessed men and vehicles were buried. They attacked the treacherous shapeless mass of earth with a passion which was a mixture of hatred and stale fear, an expression of their own relief at having escaped that smothering entombing yellow cascade.

For the first hour they dug men out alive, some miraculously protected by an overturned cart or the body of a dead mule. one of &these survivors rose shakily to his feet unaided when the earth was shovelled away, and the rescuers cheered him with a kind of wild hysteria.

Three mules had survived the drop (one of these was Zouga's old grey Bishop) but others were fearfully mutilated by the wrecked carts. Someone lowered a pistol and a packet of cartridges from the ground level and Zouga slipped and slid from one team to the other and shot the unfortunate beasts as they lay screaming and kicking in the mud.

While this was going on there were teams of men busy above them at ground level. Under the direction of the Diggers" Committee they were rigging rope ladders and a makeshift gantry to bring up the dead and the injured.

By noon that day they could begin taking the injured out, strapped to six-by-three timber boards and hoisted on the new gantry, swaying up the high wall of the pit.

Then they began to find the dead men.

The last of the missing men was locked like a foetus into the cold muddy womb of the earth. Zouga and Bazo stooped shoulder to shoulder into the mouth of the excavation, seized the limp wrist that protruded from the bank and, straining together, freed the corpse. It came out in a rush of slippery mud, like the moment of birth, but the man's limbs were convulsed in rigor mortis and his eye sockets packed with mud. Other hands lifted the corpse and carried it away, and Zouga flexed his back and groaned. Cold and weariness had tied knots in his muscles.

"We are not finished yet," he said, and the young Matabele nodded.

"What is there still to do?" he asked simply, and Zouga felt a rush of gratitude and -affection towards him. He placed his hand on Bazo's shoulder and for a moment they considered each other gravely, then Bazo asked again, "What must be done?"

"The roadway is gone. There will be no work on these claims, not for a long time," Zouga explained, his voice dulled and his hand dropping wearily from Bazo's shoulder. "If we leave any tools or equipment down here, they will be stolen."
