Some say they were planted in the old days.’
‘Splendid!’ said Frodo. ‘If we make as good going this afternoon as we have done this morning, we shall have left the Downs before the Sun sets and be jogging on in search of a camping place.’ But even as he spoke he turned his glance eastwards, and he saw that on that side the hills were higher and looked down upon them; and all those hills were crowned with green mounds, and on some were standing stones, pointing upwards like jagged teeth out of green gums.
That view was somehow disquieting; so they turned from the sight and went down into the hollow circle. In the midst of it there stood a single stone, standing tall under the sun above, and at this hour casting no shadow. It was shapeless and yet significant: like a landmark, or a guarding finger, or more like a warning. But they were now hungry, and the sun was still at the fearless noon; so they set their backs against the east side of the stone. It was cool, as if the sun had had no power to warm it; but at that time this seemed pleasant. There they took food and drink, and made as good a noon-meal under 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
