The main and greater part of the garage was approached on an asphalt ramp as rough, streaked, gouged, flecked, and bubbled as a hardened volcanic flow. In the wide green door opened to admit motored vehicles, there was a little mansized door with keep closed dribblingly dabbed in blue touch-up paint below the latch. Caldwell lifted the latch and entered. His hurt leg cursed the turn needed to close the door behind him.

A deep warm darkness was lit by sparks. The floor of the grotto was waxed black by oil drippings. At the far side of the long workbench, two shapeless men in goggles caressed a great downward-drooping fan of flame broken into dry drops. Another man, staring upward out of round eyes sockets white in a black face, rolled by on his back and disappeared beneath the body of a car. His eyes adjusting to the gloom, Caldwell saw heaped about him overturned fragments of automobiles, fragile and phantasmal, fenders like corpses of turtles, bristling engines like disembodied hearts. Hisses and angry thumps lived in the mottled air. Near where Caldwell stood, an old potbellied coal stove bent brilliant pink through its seams. He hesitated to leave its radius of warmth, though the thing in his ankle was thawing, and his stomach assuming an unsettled flutter.

Hummel himself appeared in the doorway of the workshop. As they walked toward each other, Caldwell experienced a mocking sensation of walking toward a mirror, for Hummel also limped. One of his legs was smaller than the other, due to a childhood fall. He looked hunched, pale, weathered; the recent years had diminished the master mechanic. The Esso and Mobilgas chains had both built service stations a few blocks away along the pike, and now that the war was over, and everybody could buy new cars with their war-work money, the demand for repairs had plummeted.

“George! Is it your lunch already?” Hummel’s voice, though slight, was expertly pitched to pierce the noise of the shop.

As Caldwell answered, a particularly harsh and rapid series of metallic clashes sprang up in the air and flattened his words; his voice, thin and strained, seemed to hang hushed in his own ears. “No, Jesus, I have a class right now.”

“Well what is it then?” Hummel’s delicate gray face, bleached by spots of silver bristle, alerted timidly, as if anything unexpected had the power to hurt him. His wife had done that to him, Caldwell knew.

“Lookit,” Caldwell said, “what one of the damn kids did to me.” He put his injured foot up on a severed fender and lifted his trouser leg.

The mechanic bent over the arrow and touched the feathers tentatively. His knuckles were deeply ingrained with grime, his touch silken with lubricant. “Steel shaft,” he said. “You’re lucky the tip went clean through.” He signaled and a little tripod on wheels came rattling by itself across the bumpy black floor. Hummel took from it a pair of wire cutters, the type that has an elbow hinge on one jaw to give extra leverage. As the string of a helium balloon slips from a child’s absentminded fingers, so fear set Caldwell ’s mind floating free. In his dizzy abstraction he tried to analyze the cutters as a diagram: mechanical advantage equals load over force less friction, length of lever AF (fulcrum = nut) over length FB, B being biting point of gleaming crescent jaw, multiplied by secondary mechanical advantage of accessory fulcrum-lever complex, in turn multiplied by mechanical advantage of Hummel’s calm and grimy workman’s hand, clenching action of contracting flexors and rigid phalanges five-fold, MA X MA X 5MA = titanic. Hummel bent his back so Caldwell could brace himself on his shoulders. Uncertain this was being offered and reluctant to presume, Caldwell remained erect and stared upward. The beaded boards of the garage ceiling had been painted velvet by rising smoke and spider traces. Through his knee Caldwell felt Hummel’s back shift with twitches of fitting; he felt metal touch his skin through his sock. The fender shuddered unsteadily. Hummel’s shoulders tensed with effort and Caldwell clamped his teeth upon an outcry, for it seemed the cutters were biting not into a metal shaft but into a protruding nerve of his anatomy. The crescent jaws gnashed; in a swift telescopic thrust Caldwell’s pain shot upwards; coruscated; and then Hummel’s shoulders relaxed. “No good,” the mechanic said. “I thought it might be hollow but it isn’t. George, you’ll have to come over to the bench.”

Trembling through the length of his legs, which seemed as thin and rickety as bicycle spokes, Caldwell followed Hummel and obediently set his foot up on an old Coca-Cola case the mechanic rummaged out of the sooty rubble beneath the long workbench. Trying to ignore the arrow that like an optical defect in his lower vision followed him everywhere, Caldwell concentrated on a bushel-basket full of discarded fuel pumps. Hummel pulled the chain of a naked electric bulb. The windows were opaquely spattered with paint from the outside; the walls between them were hung with wrenches aligned by size, ballpeen hammers with taped handles, electric drills, screwdrivers a yard long, intricate sprocketed socketed tools whose names and functions he would never know, neat coils of frazzled wire, calipers, pliers, and, stuck and taped here and there in crevices and bare spots, advertisements, toasted and tattered and ancient. One showed a cat holding up a paw and another a giant trying in vain to tear a patented fan belt. A card said safety first and another, taped over a window pane, protect your N N you won’t be given another pair.

Like the outpouring of a material hymn to material creation, the top of the bench was strewn with loops of rubber, tubes of copper, cylinders of graphite, threaded elbows of iron, cans of oil, chunks of wood, rags, drops, and dusty scraps of all elements. This tumble, full of tools, was raked by intense flashes of light from the two workmen down the bench. They were fashioning what looked like an ornamented bronze girdle for a woman with a tiny waist and flaring hips. Hummel put an asbestos glove on his left hand and plucked a broad scrap of tin from the heap. With the cutters he sliced into the center and, abruptly deft, cleverly folded the piece into a cupped shield, which he fitted around the arrow at the back of Caldwell ’s ankle. “So you won’t feel the heat so much,” he explained, and snapped the fingers of his un gloved hand. “Archy, could I have the torch a minute now?”

The helper, careful to keep his feet from tangling in the trailing wire, brought over the acetylene torch. It was a little black jug spitting white flame edged with green. Where the flame streamed from the spout there was a transparent gap. Caldwell locked his jaw on his panic. The arrow had been re vealed to him as a live nerve. He braced for the necessary pain.

There was none. Magically, he found himself at the center of an immense insensible nimbus. The light startled into being sharp triangular shadows all around him, on the bench, on the walls. Holding the tin shield in his gloved hand, Hummel without the protection of goggles squinted into the blazing, purring heart of Caldwell ’s ankle. His face, dead-pale and drastically foreshortened, glittered fanatically on the points of his two eyes. As Caldwell looked down, a wisp of Hummel’s tired gray hair strayed forward, shrivelled, and vanished in a whiff of smoke. The workmen watched mutely. It seemed to be taking too long. Now Caldwell was feeling the heat; the touch of tin began to boil against his leg. But by closing his eyes Caldwell could envision in the top of his skull the arrow bending, melting, its molecules letting go. Something metal and small chinked to the floor. The pressures encircling his foot lifted. He opened his eyes, and the torch went off. The yellow electric light seemed brown.

“Ronnie, could you get me a soaking wet rag?” Hummel explained to Caldwell, “I don’t want to pull it through hot.”
