About four days from the enchanted stream they came to a part where most of the trees were beeches. They were at first inclined to be cheered by the change, for here there was no undergrowth and the shadow was not so deep. There was a greenish light about them, and in places they could see some distance to either side of the path. Yet the light only showed them endless lines of straight grey trunks like the pillars of some huge twilight hall. There was a breath of air and a noise of wind, but it had a sad sound. A few leaves came rustling down to remind them that outside autumn was coming on. Their feet ruffled among the dead leaves of countless other autumns that drifted over the banks of the path from the deep red carpets of the forest.
Still Bombur slept and they grew very weary. At times they heard disquieting laughter. Sometimes there was singing in the distance too. The laughter was the laughter of fair voices not of goblins, and the singing was beautiful, but it sounded eerie and strange, and they were not comforted, rather they hurried on from those parts with what strength they had left.
Two days later they found their path going downwards, and before long they were in a valley filled almost entirely with a mighty growth of oaks.
“Is there no end to this accursed forest?” said Thorin. “Somebody must climb a tree and see if he can get his head above the roof and have a look round. The only way is to choose the tallest tree that overhangs the path.”
Of course “somebody” meant Bilbo. They chose him, because to be of any use the climber must get his head above the topmost leaves, and so he must be light enough for the highest and slenderest branches to bear him. Poor Mr. Baggins had never had much practice in climbing trees, but they hoisted him up into the lowest branches of an enormous oak that grew right out into the path, and up he had to go as best he could. He pushed his way through the tangled twigs with many a slap in the eye; he was greened and grimed from the old bark of the greater boughs; more than once he slipped and caught himself just in time; and at last, after a dreadful struggle in a difficult place where there seemed to be no convenient branches at all, he got near the top. All the time he was wondering whether there were spiders in the tree, and how he was going to get down again (except by falling).
In the end he poked his head above the roof of leaves, and then he found spiders all right. But they were only small ones of ordinary size, and they were after the butterflies. Bilbo’s eyes were nearly blinded by the light. He could hear the dwarves shouting up at him from far below, but he could not answer, only hold on and blink. The sun was shining brilliantly, and it was a long while before he could bear it. When he could, he saw all round him a sea of dark green, ruffled here and there by the breeze; and there were everywhere hundreds of butterflies. I expect they were a kind of “purple emperor”, a butterfly that loves the tops of oak-woods, but these were not purple at all, they were a dark dark velvety black without any markings to be seen.
He looked at the “black emperors” for a long time, and enjoyed the feel of the breeze in his hair and on his face; but at length the cries of the dwarves, who were now simply stamping with impatience down below, reminded him of his real business. It was no good. Gaze as much as he might, he could see no end to the trees and the leaves in any direction. His heart, that had been lightened by the sight of the sun and the feel of the wind, sank back into his toes: there was no food to go back to down below.
Actually, as I have told you, they were not far off the edge of the forest; and if Bilbo had had the sense to see it, the tree that he had climbed, though it was tall in itself, was standing near the bottom of a wide valley, so that from its top the trees seemed to swell up all round like the edges of a great bowl, and he could not expect to see how far the forest lasted. Still he did not see this, and he climbed down full of despair. He got to the bottom again at last, scratched, hot, and miserable, and he could not see anything in the gloom below when he got there. His report soon made the others as miserable as he was.
“The forest goes on for ever and ever and ever in all directions! Whatever shall we do? And what is the use of sending a hobbit!” they cried, as if it was his fault. They did not care tuppence about the butterflies, and were only made more angry when he told them of the beautiful breeze, which they were too heavy to climb up and feel.
That night they ate their very last scraps and crumbs of food; and next morning when they woke the first thing they noticed was that they were still gnawingly hungry, and the next thing was that it was raining and that here and there the drip of it was dropping heavily on the forest floor. That only reminded them that they were also parchingly thirsty, without doing anything to relieve them: you cannot quench a terrible thirst by standing under giant oaks and waiting for a chance drip to fall on your tongue. The only scrap of comfort there was came unexpectedly from Bombur.
He woke up suddenly and sat up scratching his head. He could not make out where he was at all, nor why he felt so hungry; for he had forgotten everything that had happened since they started their journey that May morning long ago. The last thing that he remembered was the party at the hobbit’s house, and they had great difficulty in making him believe their tale of all the many adventures they had had since.
When he heard that there was nothing to eat, he sat down and wept, for he felt very weak and wobbly in the legs. “Why ever did I wake up!” he cried. “I was having such beautiful dreams. I dreamed I was walking in a forest rather like this one, only lit with torches on the trees and lamps swinging from the branches and fires burning on the ground; and there was a great feast going on, going on for ever. A woodland king was there with a crown of leaves, and there was a merry singing, and I could not count or describe the things there were to eat and drink.”
“You need not try,” said Thorin. “In fact if you can’t talk about something else, you had better be silent. We are quite annoyed enough with you as it is. If you hadn’t waked up, we should have left you to your idiotic dreams in the forest; you are no joke to carry even after weeks of short commons.”
There was nothing now to be done but to tighten the belts round their empty stomachs, and hoist their empty sacks and packs, and trudge along the track without any great hope of ever getting to the end before they lay down and died of starvation. This they did all that day, going very slowly and wearily; while Bombur kept on wailing that his legs would not carry him and that he wanted to lie down and sleep.
“No you don’t!” they said. “Let your legs take their share, we have carried you far enough.”
