years before he found out, with the aid of an electron microscope, that aside from the function of exact duplication, Tree B was different. In the nucleus of each cell of Tree B was a single giant molecule, akin to the hydrocarbon enzymes, which could transmute elements. Three cells removed from a piece of bark or leaf-tissue meant three cells replaced within an hour. The freak enzyme, depleted, would then rest for an hour or two, and slowly begin to restore itself, atom by captured atom, from the surrounding tissue.
The control of restoration in damaged tissue is a subtle business at its simplest. Any biologist can give a lucid description of what happens when cells begin to rebuild—what metabolistic factors are present, what oxygen exchange occurs, how fast and how large and for what purpose new cells are developed. But they cannot tell you why. They cannot say what gives the signal, “Start!” to a half-ruined cell, and what says “stop.” They know that cancer is a malfunction of this control mechanism, but what the mechanism is they do not say. This is true of normal tissue.
But what of Pierre Monetre’s Tree B? It never restored itself normally. It restored itself only to duplicate Tree A. Notch a twig of Tree A. Break off the corresponding twig of Tree B and take it home. For twelve to fourteen hours, that twig would work on the laborious process of reforming itself to be notched. After that it would stop, and be an ordinary piece of wood. Return then to Tree B, and you would find another restored twig, and this one with its notch perfectly duplicated.
Here even Pierre Monetre’s skill bogged down. Cell regeneration is a mystery. Cell duplication is a step beyond an unfathomable enigma. But somewhere, somehow, this fantastic duplication was controlled, and Monetre doggedly set about finding what did it.
He was a savage, hearing a radio and searching for the signal source. He was a dog, hearing his master cry out in pain because a girl wrote that she did not love him. He saw the result, and he tried, without adequate tools, without the capacity to understand it if it were thrust under his nose, to determine the cause.
A fire did it for him.
The few people who knew him by sight—none knew him any other way—were astonished that he joined the volunteer fire-fighters that autumn, when the smoke blasted through the hills driven by a flame-whipped wind. And for years there was a legend about the skinny feller who fought the fire like a soul promised release from hell. They told about cutting the new fire-trail, and how the skinny feller threatened to kill the forest ranger if he did not move his fire line a hundred yards north of where it had been planned. The skinny feller made history with his battle of the back-blaze, watering it with his very sweat to keep it out of a certain patch of wood. And when the fire advanced to the edge of the back-blaze, and the men broke and fled before it, the skinny feller was not with them, but stayed, crouched in the smoking moss between two oak saplings, with a spade and an axe in his bleeding hands and a fire in his eyes hotter than any that ever touched a tree. They saw all of that—
They did not see Tree B begin to tremble. Their eyes were not with Monetre’s, to peer through heat and smoke and the agonized cloud of exhaustion which hovered around him, and see the scientist’s mind reaching out to seize on the fact that the shuddering of Tree B was timed exactly with the rolling flames over a clearing fifty feet away.
He watched it, red-eyed. Flame touched the rocky clearing, and the tree shivered. Flame tugged the earth like hair in a hurricane pulling a scalp, and when the fire wavered and streamed upward, Tree B stood firm. But when a tortured gust of cold air rushed in to fill the heat-born vacuum, and was pursued along the ground by fingers of fire, the tree shook and tensed, wavered and trembled.
Monetre dragged his half-flayed body to the clearing and
