The Lord of the Rings

the open sky as anyone could wish; for the food came from ‘down under Hill’. Tom had provided them with plenty for the comfort of the day. Their ponies unburdened strayed upon the grass.
    Riding over the hills, and eating their fill, the warm sun and the scent of turf, lying a little too long, stretching out their legs and looking at the sky above their noses: these things are, perhaps, enough to explain what happened. However that may be: they woke suddenly and uncomfortably from a sleep they had never meant to take. The standing stone was cold, and it cast a long pale shadow that stretched eastward over them. The sun, a pale and watery yellow, was gleaming through the mist just above the west wall of the hollow in which they lay; north, south, and east, beyond the wall the fog was thick, cold and white. The air was silent, heavy and chill. Their ponies were standing crowded together with their heads down.
    The hobbits sprang to their feet in alarm, and ran to the western rim. They found that they were upon an island in the fog. Even as they looked out in dismay towards the setting sun, it sank before their eyes into a white sea, and a cold grey shadow sprang up in the East behind. The fog rolled up to the walls and rose above them, and as it mounted it bent over their heads until it became a roof: they were shut in a hall of mist whose central pillar was the standing stone.
    They felt as if a trap was closing about them; but they did not quite lose heart. They still remembered the hopeful view they had had of the line of the Road ahead, and they still knew in which direction it lay. In any case, they now had so great a dislike for that hollow place about the stone that no thought of remaining there was in their minds. They packed up as quickly as their chilled fingers would work.
    Soon they were leading their ponies in single file over the rim and down the long northward slope of the hill, down into a foggy sea. As they went down the mist became colder and damper, and their hair hung lank and dripping on their foreheads. When they reached the bottom it was so chill that they halted and got out cloaks and hoods, which soon became bedewed with grey drops. Then, mounting their ponies, they went slowly on again, feeling their way by the rise and fall of the ground. They were steering, as well as they could guess, for the gate-like opening at the far northward end of the long valley which they had seen in the morning. Once they were through the gap, they had only to keep on in anything like a straight line and they were bound in the end to strike the Road. Their thoughts did not go beyond that, except for a vague hope that perhaps away beyond the Downs there might be no fog.
    Their going was very slow. To prevent their getting separated and wandering in different directions they went in file, with Frodo leading. Sam was behind him, and after him came Pippin, and then Merry. The valley seemed to stretch on endlessly. Suddenly Frodo saw a hopeful sign. On either side ahead a darkness began to loom through the mist; and he guessed that they were at last approaching the gap in the hills, the north-gate of the Barrow-downs. If they could pass that, they would be free.
    ‘Come on! Follow me!’ he called back over his shoulder, and he hurried forward. But his hope soon changed to bewilderment and alarm. The dark patches grew darker, but they shrank; and suddenly he saw, towering ominous before him and leaning slightly towards one another like the pillars of a headless door, two huge standing stones. He could not remember having seen any sign of these in thevalley, when he looked out from the hill in the morning. He had passed between them almost before he was aware: and even as he did so darkness seemed to fall round him. His pony reared and snorted, and he fell off. When he looked back he found that he was alone: the others had not followed him.
    ‘Sam!’ he called. ‘Pippin! Merry! Come along! Why don’t you keep up?’
    There was no answer. Fear took him, and he ran back past the stones shouting wildly: ‘Sam! Sam! Merry! Pippin!’ The pony bolted into the mist and vanished. From some way off, or so it seemed, he thought he heard a cry: ‘Hoy! Frodo! Hoy!’ It was away eastward, on his left as he stood under the great stones, staring and straining into the gloom. He plunged off in the direction of the call, and found himself going steeply uphill.
    As he struggled on he called again, and kept on calling more
