It was about ten minutes later when all four of them (the two children wet nearly all over) came out and began to notice their surroundings. The moon was now high enough to peep down into the valley. There was soft grass on both sides of the river, and beyond the grass, trees and bushes sloped up to the bases of the cliffs. There must have been some wonderful flowering shrubs hidden in that shadowy undergrowth for the whole glade was full of the coolest and most delicious smells. And out of the darkest recess among the trees there came a sound Shasta had never heard beforea nightingale.
Everyone was much too tired to speak or to eat. The Horses, without waiting to be unsaddled, lay down at once. So did Aravis and Shasta.
About ten minutes later the careful Hwin said, "But we mustn't go to sleep. We've got to keep ahead of that Rabadash."
"No," said Bree very slowly. "Mustn't go sleep. Just a little rest."
Shasta knew (for a moment) that they would all go to sleep if he didn't get up and do something about it, and felt that he ought to. In fact he decided that he would get up and persuade them to go on. But presently; not yet: not just yet...
Very soon the moon shone and the nightingale sang over two horses and two human children, all fast asleep.
It was Aravis who awoke first. The sun was already high in the heavens and the cool morning hours were already wasted. "It's my fault," she said to herself furiously as she jumped up and began rousing the others. "One wouldn't expect Horses to keep awake after a day's work like that, even if they can talk. And of course that Boy wouldn't; he's had no decent training. But I ought to have known better."
The others were dazed and stupid with the heaviness of their sleep.
"Neigh-ho - broo-hoo," said Bree. "Been sleeping in my saddle, eh? I'll never do that again. Most uncomfortable-"
"Oh come on, come on," said Aravis. "We've lost half the morning already. There isn't a moment to spare."
"A fellow's got to have a mouthful of grass," said Bree.
"I'm afraid we can't wait," said Aravis.
