Roy grinned.

’Thank goodness, tracking is about the last thing that would occur to a German.  All the same, Kemp is quite cute enough to leave a guard posted here to watch for us.’

Ken looked rather startled.

’I hadn’t thought of that, but it’s very likely.  Then it looks as if we should have to stay here all night.’

‘I’d made up my mind to that already,’ Roy answered.  ’But it might be worse.  We’ve got shelter and we’re absolutely safe.  Also we have our emergency rations, so we shan’t starve.  We ought to get a decent sleep for once in a way.’

‘What—­sleep on the edge of this precipice!’

‘Why not?  I’ve slept in worse places before now.’

‘Supposing one rolled over in one’s sleep?’ said Ken with a slight shiver as he peered over into the awesome depths below.

Roy laughed softly.

’Don’t worry.  You shall sleep between me and the rock.  It’ll take you all your time to roll over me.’

The sun was down, darkness was already shrouding the depths of space beneath them.  The Turks seemed to have left.  At any rate, Ken and Roy could hear no more of them.  The evening silence was broken only by the mysterious whisper of the evening breeze as it stole down the canon, and by a faint and distant popping of rifle shots.

Roy stretched his long legs and yawned.

‘I’m for supper,’ he observed, as he took his iron ration out of his haversack.  ’We’ll share this to-night, Ken, and breakfast off yours in the morning.  Luckily I’ve still got some water in my bottle.’

The emergency or iron ration consists mainly of concentrated beef, biscuit, and chocolate.  There is not much of it, so far as bulk goes, but it is very sustaining.  Roy carefully divided his into two lots, and they ate slowly, and finished their slim repast with a drink of water.

Then, after chatting a while, they stretched themselves out to sleep.  Roy, according to his promise, made Ken take the inner side, and in spite of his nervousness, he slept like a log.

Ken roused at earliest dawn.  A thin mist floated beneath them, hiding the depths of the ravine.  Musketry still crackled in the distance, but all around was very still.

Ken shivered slightly, for the morning air bit chill.  He sat up and shook Roy, who was still sleeping peacefully.

‘Daylight,’ said Ken briefly.  ‘Time to get out of this.’

Roy sat up and stretched his great frame.

‘What a life!’ he said with a laugh.  ’Yes, I suppose we’d best be shifting.’

‘Shall we breakfast now, or wait till we get up topside?’ asked Ken.

Roy gave him a quick look.

‘It might be as well to feed now,’ he said quietly.  ’You see, I haven’t a notion how we’re going to get out of this.’

Ken stared.  Such a point of view had never occurred to him.  He had such implicit faith in Roy’s mountaineering capacity that he had taken it absolutely for granted that Roy could find a way back to firm ground.
