In anxious suspense I watched him as he came gradually up toward me, shooting from side to side of the cell in upward-slanting leaps that brought him each many feet upward. Gradually, though, I saw that the force of his leaps was lessening, his upward progress slowing, as he, too, began to feel the waning of his strength. I knew that, older than myself as he was, those leaps were telling against Marlin even more than they had done against me, and in utmost suspense I watched as he came more and more slowly toward me. At last he was but a score or more feet beneath, his face tense and strained as he shot from wall to wall, gaining now but a few feet each leap. With clenched fingers I watched him, powerless to help, saw him by a last gathering of his strength making another up-slanting leap and another and another, until but one more was needed to reach up to the wall on which I crouched. And even as Marlin made that last leap, even as he shot across the cell's width and up toward the wall on which I crouched, I realized with a thrill of horror that he had leaped short! In that moment, as Marlin shot across the cell's width toward me with hands outstretched, I saw his white, strained face and knew that even as I did he realized the shortness of the leap that he had made with his last strength, realized that his outstretched hands would miss the wall's top by feet. That moment in which he shot across the cell, as his own hands struck the smooth wall of length, yet as he shot toward me it was more by instinct than by conscious thought that I acted. Swiftly hooking my knees over the wall's top upon which I crouched, I hung with head and body downward into the cell, reached downward with hands open, and as Marlin shot across the cell, as his own hands struck the smooth wall of it many feet below the top, I reached and grasped them tightly. A moment thus we hung there, he held by my own down-swinging body, and then holding his own hand by one of mine I reached upward with the other, drew myself slowly and with an infinite effort upward. In another moment I had drawn myself and Marlin on to the wall's top, and there crouched with him again in a silence of exhaustion for the moment. Only his and my own lessened weight, on Triton, had made it possible for me thus to save him.
