At first their choice seemed to be good: they got along at a fair speed, though whenever they got a glimpse of the sun in an open glade they seemed unaccountably to have veered eastwards. But after a time the trees began to close in again, just where they had appeared from a distance to be thinner and less tangled. Then deep folds in the ground were discovered unexpectedly, like the ruts of great giant-wheels or wide moats and sunken roads long disused and choked with brambles. These lay usually right across their line of march, and could only be crossed by scrambling down and out again, which was troublesome and difficult with their ponies. Each time they climbed down they found the hollow filled with thick bushes and matted undergrowth, which somehow would not yield to the left, but only gave way when they turned to the right; and they had to go some distance along the bottom before they could find a way up the further bank. Each time they clambered out, the trees seemed deeper and darker; and always to the left and upwards it was most difficult to find a way, and they were forced to the right and downwards.
After an hour or two they had lost all clear sense of direction, though they knew well enough that they had long ceased to go northward at all. They were being headed off, and were simply following a course chosen for them – eastwards and southwards, into the heart of the Forest and not out of it.
The afternoon was wearing away when they scrambled and stumbled into a fold that was wider and deeper than any they had yet met. It was so steep and overhung that it proved impossible to climb out of it again, either forwards or backwards, without leaving their ponies and their baggage behind. All they could do was to follow the fold – downwards. The ground grew soft, and in places boggy; springs appeared in the banks, and soon they found themselves following a brook that trickled and babbled through a weedy bed. Then the ground began to fall rapidly, and the brook growing strong and noisy, flowed and leaped swiftly downhill. They were in a deep dim-lit gully over-arched by trees high above them.
After stumbling along for some way along the stream, they came quite suddenly out of the gloom. As if through a gate they saw the sunlight before them. Coming to the opening they found that they had made their way down through a cleft in a high steep bank, almost a cliff. At its feet was a wide space of grass and reeds; and in the distance could be glimpsed another bank almost as steep. A golden afternoon of late sunshine lay warm and drowsy upon the hidden land between. In the midst of it there wound lazily a dark river of brown water, bordered with ancient willows, arched over with willows, blocked with fallen willows, and flecked with thousands of faded willow-leaves. The air was thick with them, fluttering yellow from the branches; for there was a warm and gentle breeze blowing softly in the valley, and the reeds were rustling, and the willow-boughs were creaking.
‘Well, now I have at least some notion of where we are!’ said Merry. ‘We have come almost in the opposite direction to which we intended. This is the River Withywindle! I will go on and explore.’
He passed out into the sunshine and disappeared into the long grasses. After a while he reappeared, and reported that there was fairly solid ground between the cliff-foot and the river; in some places firm turf went down to the water’s edge. ‘What’s more,’ he said, ‘there seems to be something like a footpath winding along on this side of the river. If we turn left and follow it, we shall be bound to come out on the east side of the Forest eventually.’
‘I dare say!’ said Pippin. ‘That is, if the track goes on so far, and does not simply lead us into a bog and leave us there. Who made the track, do you suppose, and why? I am sure it was not for our benefit. I am getting very suspicious of this Forest and everything in it, and I begin to believe all the stories about it. And have you any idea how far eastward we should have to go?’
‘No,’ said Merry, ‘I haven’t. I don’t know in the least how far down the Withywindle we are, or who could possibly come here often enough to make a path along it. But there is no other way out that I can see or think of.’
There being nothing else for it, they filed out, and Merry led them to the path that he had discovered. Everywhere the reeds and grasses were lush and tall, in places far above their heads; but once found, the path was easy to follow, as it turned and twisted, picking out the sounder ground among the bogs and pools. Here and there it passed over other rills, running down gullies into the Withywindle out of the higher forest-lands, and at these points there were tree-trunks or bundles of brushwood laid carefully across.
The hobbits began to feel very hot. There were armies of flies of all kinds buzzing round their ears, and the afternoon sun was burning on their backs. At last they came suddenly into a thin shade; great grey branches reached across the path. Each step forward became more reluctant than the last. Sleepiness seemed to be creeping out of the ground and up their legs, and falling softly out of the air upon their heads and eyes.
