From that time on Sam thought that he sensed a change in Gollum again. He was more fawning and would-be friendly; but Sam surprised some strange looks in his eyes at times, especially towards Frodo; and he went back more and more into his old manner of speaking. And Sam had another growing anxiety. Frodo seemed to be weary, weary to the point of exhaustion. He said nothing, indeed he hardly spoke at all; and he did not complain, but he walked like one who carries a load, the weight of which is ever increasing; and he dragged along, slower and slower, so that Sam had often to beg Gollum to wait and not to leave their master behind.
In fact with every step towards the gates of Mordor Frodo felt the Ring on its chain about his neck grow more burdensome. He was now beginning to feel it as an actual weight dragging him earthwards. But far more he was troubled by the Eye: so he called it to himself. It was that more than the drag of the Ring that made him cower and stoop as he walked. The Eye: that horrible growing sense of a hostile will that strove with great power to pierce all shadows of cloud, and earth, and flesh, and to see you: to pin you under its deadly gaze, naked, immovable. So thin, so frail and thin, the veils were become that still warded it off. Frodo knew just where the present habitation and heart of that will now was: as certainly as a man can tell the direction of the sun with his eyes shut. He was facing it, and its potency beat upon his brow.
Gollum probably felt something of the same sort. But what went on in his wretched heart between the pressure of the Eye, and the lust of the Ring that was so near, and his grovelling promise made half in the fear of cold iron, the hobbits did not guess: Frodo gave no thought to it. Sam's mind was occupied mostly with his master hardly noticing the dark cloud that had fallen on his own heart. He put Frodo in front of him now, and kept a watchful eye on every movement of his, supporting him if he stumbled, and trying to encourage him with clumsy words.
When day came at last the hobbits were surprised to see how much closer the ominous mountains had already drawn. The air was now clearer and colder, and though still far off, the walls of Mordor were no longer a cloudy menace on the edge of sight, but as grim black towers they frowned across a dismal waste. The marshes were at an end, dying away into dead peats and wide flats of dry cracked mud. The land ahead rose in long shallow slopes, barren and pitiless, towards the desert that lay at Sauron's gate.
While the grey light lasted, they cowered under a black stone like worms, shrinking, lest the winged terror should pass and spy them with its cruel eyes. The remainder of that journey was a shadow of growing fear in which memory could find nothing to rest upon. For two more nights they struggled on through the weary pathless land. The air, as it seemed to them, grew harsh, and filled with a bitter reek that caught their breath and parched their mouths.
At last, on the fifth morning since they took the road with Gollum, they halted once more. Before them dark in the dawn the great mountains reached up to roofs of smoke and cloud. Out from their feet were flung huge buttresses and broken hills that were now at the nearest scarce a dozen miles away. Frodo looked round in horror. Dreadful as the Dead Marshes had been, and the arid moors of the Noman-lands, more loathsome far was the country that the crawling day now slowly unveiled to his shrinking eyes. Even to the Mere of Dead Faces some haggard phantom of green spring would come; but here neither spring nor summer would ever come again. Here nothing lived, not even the leprous growths that feed on rottenness. The gasping pools were choked with ash and crawling muds, sickly white and grey, as if the mountains had vomited the filth of their entrails upon the lands about. High mounds of crushed and powdered rock, great cones of earth fire-blasted and poison-stained, stood like an obscene graveyard in endless rows, slowly revealed in the reluctant light.
They had come to the desolation that lay before Mordor: the lasting monument to the dark labour of its slaves that should endure when all their purposes were made void; a land defiled, diseased beyond all healing – unless the Great Sea should enter in and wash it with oblivion. 'I feel sick,' said Sam. Frodo did not speak.
For a while they stood there, like men on the edge of a sleep where nightmare lurks, holding it off, though they know that they can only come to morning through the shadows. The light broadened and hardened. The gasping pits and poisonous mounds grew hideously clear. The sun was up, walking among clouds and long flags of smoke, but even the sunlight was defiled. The hobbits had no welcome for that light; unfriendly it seemed, revealing them in their helplessness – little squeaking ghosts that wandered among the ash-heaps of the Dark Lord.
