That morning they lit a fire in a deep hollow shrouded by great bushes of holly, and their supper-breakfast was merrier than it had been since they set out. They did not hurry to bed afterwards, for they expected to have all the night to sleep in, and they did not mean to go on again until the evening of the next day. Only Aragorn was silent and restless. After a while he left the Company and wandered on to the ridge; there he stood in the shadow of a tree, looking out southwards and westwards, with his head posed as if he was listening. Then he returned to the brink of the dell and looked down at the others laughing and talking.
`What is the matter, Strider?' Merry called up. 'What are you looking for? Do you miss the East Wind?'
'No indeed,' he answered. `But I miss something. I have been in the country of Hollin in many seasons. No folk dwell here now, but many other creatures live here at all times, especially birds. Yet now all things but you are silent. I can feel it. There is no sound for miles about us, and your voices seem to make the ground echo. I do not understand it.'
Gandalf looked up with sudden interest. `But what do you guess is the reason?' he asked. `Is there more in it than surprise at seeing four hobbits, not to mention the rest of us, where people are so seldom seen or heard?'
`I hope that is it,' answered Aragorn. `But I have a sense of watchfulness, and of fear, that I have never had here before.'
"Then we must be more careful,' said Gandalf. 'If you bring a Ranger with you, it is well to pay attention to him, especially if the Ranger is Aragorn. We must stop talking aloud, rest quietly, and set the watch.'
It was Sam's turn that day to take the first watch, but Aragorn joined him. The others fell asleep. Then the silence grew until even Sam felt it. The breathing of the sleepers could be plainly heard. The swish of the pony's tail and the occasional movements of his feet became loud noises. Sam could hear his own joints creaking, if he stirred. Dead silence was around him, and over all hung a clear blue sky, as the Sun rode up from the East. Away in the South a dark patch appeared, and grew, and drove north like flying smoke in the wind.
`What's that, Strider? It don't look like a cloud ...'
... said Sam in a whisper to Aragorn. He made no answer, he was gazing intently at the sky; but before long Sam could see for himself what was approaching. Flocks of birds, flying at great speed, were wheeling and circling, and traversing all the land as if they were searching for something; and they were steadily drawing nearer.
`Lie flat and still!' hissed Aragorn, pulling Sam down into the shade of a holly-bush; for a whole regiment of birds had broken away suddenly from the main host, and came, flying low, straight towards the ridge. Sam thought they were a kind of crow of large size. As they passed overhead, in so dense a throng that their shadow followed them darkly over the ground below, one harsh croak was heard.
Not until they had dwindled into the distance, north and west, and the sky was again clear would Aragorn rise. Then he sprang up and went and wakened Gandalf.
`Regiments of black crows are flying over all the land between the Mountains and the Greyflood,' he said, `and they have passed over Hollin. They are not natives here; they are crebain out of Fangorn and Dunland. I do not know what they are about: possibly there is some trouble away south from which they are fleeing; but I think they are spying out the land. I have also glimpsed many hawks flying high up in the sky. I think we ought to move again this evening. Hollin is no longer wholesome for us: it is being watched.'
`And in that case so is the Redhorn Gate,' said Gandalf; `and how we can get over that without being seen, I cannot imagine. But we will think of that when we must. As for moving as soon as it is dark, I am afraid that you are right.'
