The Mountain crept up ever nearer, until, if they lifted their heavy heads, it filled all their sight, looming vast before them: a huge mass of ash and slag and burned stone, out of which a sheer-sided cone was raised into the clouds. Before the daylong dusk ended and true night came again they had crawled and stumbled to its very feet.
With a gasp Frodo cast himself on the ground. Sam sat by him. To his surprise he felt tired but lighter, and his head seemed clear again. No more debates disturbed his mind. He knew all the arguments of despair and would not listen to them. His will was set, and only death would break it. He felt no longer either desire or need of sleep, but rather of watchfulness. He knew that all the hazards and perils were now drawing together to a point: the next day would be a day of doom, the day of final effort or disaster, the last gasp.
But when would it come? The night seemed endless and timeless, minute after minute falling dead and adding up to no passing hour, bringing no change. Sam began to wonder if a second darkness had begun and no day would ever reappear. At last he groped for Frodo's hand. It was cold and trembling. His master was shivering.
'I didn't ought to have left my blanket behind,' muttered Sam; and lying down he tried to comfort Frodo with his arms and body. Then sleep took him, and the dim light of the last day of their quest found them side by side. The wind had fallen the day before as it shifted from the West, and now it came from the North and began to rise; and slowly the light of the unseen Sun filtered down into the shadows where the hobbits lay.
'Now for it! Now for the last gasp!' said Sam as he struggled to his feet. He bent over Frodo, rousing him gently. Frodo groaned; but with a great effort of will he staggered up; and then he fell upon his knees again. He raised his eyes with difficulty to the dark slopes of Mount Doom towering above him, and then pitifully he began to crawl forward on his hands.
Sam looked at him and wept in his heart, but no tears came to his dry and stinging eyes. 'I said I'd carry him, if it broke my back,' he muttered, 'and I will!'
'Come, Mr. Frodo!' he cried. 'I can't carry it for you, but I can carry you and it as well. So up you get! Come on, Mr. Frodo dear! Sam will give you a ride. Just tell him where to go, and he'll go.'
As Frodo clung upon his back, arms loosely about his neck, legs clasped firmly under his arms, Sam staggered to his feet; and then to his amazement he felt the burden light. He had feared that he would have barely strength to lift his master alone, and beyond that he had expected to share in the dreadful dragging weight of the accursed Ring. But it was not so. Whether because Frodo was so worn by his long pains, wound of knife, and venomous sting, and sorrow, fear, and homeless wandering, or because some gift of final strength was given to him, Sam lifted Frodo with no more difficulty than if he were carrying a hobbit-child pig-a-back in some romp on the lawns or hayfields of the Shire. He took a deep breath and started off.
They had reached the Mountain's foot on its northern side, and a little to the westward; there its long grey slopes, though broken, were not sheer. Frodo did not speak, and so Sam struggled on as best he could, having no guidance but the will to climb as high as might be before his strength gave out and his will broke. On he toiled, up and up, turning this way and that to lessen the slope, often stumbling forward, and at the last crawling like a snail with a heavy burden on its back. When his will could drive him no further, and his limbs gave way, he stopped and laid his master gently down.
Frodo opened his eyes and drew a breath. It was easier to breathe up here above the reeks that coiled and drifted down below. 'Thank you, Sam,' he said in a cracked whisper. 'How far is there to go?'
'I don't know,' said Sam, 'because I don't know where we're going.'
He looked back, and then he looked up; and he was amazed to see how far his last effort had brought him. The Mountain standing ominous and alone had looked taller than it was. Sam saw now that it was less lofty than the high passes of the Ephel Duath which he and Frodo had scaled. The confused and tumbled shoulders of its great base rose for maybe three thousand feet above the plain, and above them was reared half as high again its tall central cone, like a vast oast or chimney capped with a jagged crater. But already Sam was more than half way up the base, and the plain of Gorgoroth was dim below him, wrapped in fume and shadow. As he looked up he would have given a shout. if his parched throat had allowed him; for amid the rugged humps and shoulders above him he saw plainly a path or road. It climbed like a rising girdle from the west and wound snakelike about the Mountain, until before it went round out of view it reached the foot of the cone upon its eastern side.
