'Blow!' he said. 'I really must make up my mind, or the men may be here before I'm in hiding!'

And then he suddenly had a real brainwave, and he crowed in delight. Of course! The very place!

'I'll climb up on to the roof of one of the caravans!' thought Julian. 'n.o.body will see me there - and certainly n.o.body would guess I was there! That really is a fine idea. I shall have a fine view of the track and a first-rate view of the men and where they go!'

It wasn't very easy to climb up on to the high roof. He had to get a rope, loop it at the end, and try to la.s.so the chimney in order to climb up.

He managed to la.s.so the chimney, and the rope hung down over the side of the caravan, ready for him to swarm up. He threw his packet of food up on to the roof and then climbed up himself. He pulled up the rope and coiled it beside him.

Then he lay down flat. He was certain that n.o.body could see him from below. Of course, if the men went higher up the hill and looked down on the caravans, he could easily be spotted - but he would have to chance that.

He lay there quite still, watching the lake, and keeping eyes and ears open for anyone coming up the hillside. He was glad that it was not a very hot sunny day, or he would have been cooked up on the roof. He wished he had thought of filling a bottle with water in case he was thirsty.

He saw spires of smoke rising from where the circus camp lay, far below. He saw a couple of boats on the lake, a good way round the water - people fishing, he supposed. He watched a couple of rabbits come out and play on the hillside just below.

The sun came out from behind the clouds for about ten minutes and Julian began to feel uncomfortably hot. Then it went in again and he felt better.

He suddenly heard somebody whistling and stiffened himself in expectation - but it was only someone belonging to the farm, going down the hill some distance away. The whistle had carried clearly in the still air.

Then he got bored. The rabbits went in, and not even a b.u.t.terfly sailed by. He could see no birds except a yellow-hammer that sat on the topmost spray of a bush and sang: ' Little-bit-of-bread-and-no-cheese', over and over again in a most maddening manner.

Then it gave a cry of alarm and flew off. It had heard something that frightened it.

Julian heard something, too, and glued his eyes to the track that led up the hill. His heart began to beat. He could see two men. Were they Lou and Dan?

He did not dare to raise his head to see them when they came nearer in case they spotted him. But he knew their voices when they came near enough!

Yes - it was Lou and Tiger Dan all right. There was no mistaking those two harsh, coa.r.s.e voices. The men came right into the hollow, and Julian heard them talking.

'Yes, there's n.o.body here. Those kids have really gone off for the day at least - and taken that wretched dog with them!'

'I saw them get on the bus, dog and all, I told you,' growled Lou. 'There'll be n.o.body here for the day. We can get what we want to.'

'Let's go and get it, then,' said Dan.

Julian waited to see where they would go to. But they didn't go out of the hollow. They stayed there, apparently beside the caravans. Julian did not dare to look over the edge of the roof to see what they were up to. He was glad he had fastened all the windows and locked the doors.

Then there began some curious scuffling sounds, and the men panted. The caravan on which Julian was lying began to shake a little.

'What are they doing?' thought Julian in bewilderment. In intense curiosity he slid quietly to the edge of the caravan roof and cautiously peeped over, though he had firmly made up his mind not to do this on any account.

He looked down on the ground. There was n.o.body there at all. Perhaps the men were the other side. He slid carefully across and peeped over the opposite side of the caravan, which was still shaking a little, as if the men were b.u.mping against it.

There was n.o.body the other side either! How very extraordinary! 'Golly! They must be underneath the caravan!' thought Julian, going back to the middle of the roof. 'Underneath! What in the wide world for?'

It was quite impossible to see underneath the caravan from where he was, so he had to lie quietly and wonder about the men's doings. They grunted and groaned, and seemed to be sc.r.a.ping and scrabbling about, but nothing happened. Then Julian heard them scrambling out from underneath, angry and disappointed.

'Give us a cigarette,' said Lou in a disagreeable voice. 'I'm fed up with this. Have to shift this van. Those tiresome brats! What did they want to choose this spot for?'

Julian heard a match struck and smelt cigarette smoke. Then he got a shock. The caravan he was on began to move! Heavens! Were the men going to push it over the ledge and send it rolling down the hillside?

CHAPTER FIFTEEN

SEVERAL THINGS HAPPEN

Julian was suddenly very scared. He wondered if he had better slide off the roof and run. He wouldn't have much chance if the caravan went hurtling down the hill! But he didn't move. He clung to the chimney with both hands, whilst the men shoved hard against the caravan.

It ran a few feet to the rocky ledge, and then stopped. Julian felt his forehead getting very damp, and he saw that his hands were trembling. He felt ashamed of being so scared, but he couldn't help it.

'Hey! Don't send it down the hill!' said Lou in alarm, and Julian's heart felt lighter. So they didn't mean to destroy the caravan in that way! They had just moved it to get at something underneath. But what could it be? Julian racked his brains to try and think what the floor of the hollow had been like when Dobby and Trotter pulled their caravans into it. As far as he could remember it was just an ordinary heathery hollow.

The men were now scrabbling away again by the back steps of the caravan. Julian was absolutely eaten up with curiosity, but he did not dare even to move. He could find out the secret when the men had gone. Meantime he really must be patient or he would spoil everything.

There was some muttered talking, but Julian couldn't catch a word. Then, quite suddenly, there was complete and utter silence. Not a word. Not a b.u.mp against the caravan. Not a pant or even a grunt. Nothing at all.

Julian lay still. Maybe the men were still there. He wasn't going to give himself away. He lay for quite a long time, waiting and wondering. But he heard nothing.

Then he saw a robin fly to a nearby bramble spray. It flicked its wings and looked about for crumbs. It was a robin that came around when the children were having a meal - but it was not as tame as most robins, and would not fly down until the children had, left the hollow.

Then a rabbit popped out of a hole on the hillside and capered about, running suddenly up to the hollow.

'Well,' thought Julian, 'it's plain the men aren't here now, or the birds and animals wouldn't be about like this. There's another rabbit. Those men have gone somewhere - though goodness knows where. I can peep over now and have a look, quite safely, I should think.'

He slid himself round and peered over the roof at the back end of the caravan. He looked down at the ground. There was absolutely nothing to be seen to tell him what the men had been doing, or where they had gone! The heather grew luxuriantly there as it did everywhere else. There was nothing to show what the men had been making such a disturbance about.

'This is really very queer,' thought Julian, beginning to wonder if he had been dreaming. 'The men are certainly gone - vanished into thin air, apparently! Dare I get down and explore a bit? No, I daren't. The men may appear at any moment, and it's quite on the cards they'll lose their temper if they find me here, and chuck both me and the caravans down the hill! It's pretty steep just here, too.'

He lay there, thinking. He suddenly felt very hungry and thirsty. Thank goodness he had been sensible enough to take food up to the roof! He could at least have a meal while he was waiting for the men to come back - if they ever did!

He began to eat his sandwiches. They tasted very good indeed. He finished them all and began on the cake. That was good, too. He had brought a few plums up as well, and was very glad of them because he was thirsty. He flicked the plum stones from the roof before he thought what he was doing.

'Dash! Why did I do that? If the men notice them they may remember they weren't there before. Still, they've most of them gone into the heather!'

The sun came out a little and Julian felt hot. He wished the men would come again and go down the hill. He was tired of lying flat on the hard roof. Also he was terribly sleepy. He yawned silently and shut his eyes.

How long he slept he had no idea - but he was suddenly awakened by feeling the caravan being moved again! He clutched the chimney in alarm, listening to the low voices of the two men.

They were pulling the caravan back into place again. Soon it was in the same position as before. Then Julian heard a match struck and smelt smoke again.

The men went and sat on the rocky ledge and took out food they had brought, Julian did not dare to peep at them, though he felt sure they had their backs to him. The men ate, and talked in low voices, and then, to Julian's dismay, they lay down and went to sleep! He knew that they were asleep because he could hear them snoring.

'Am I going to stay on this awful roof all day long?' he thought. 'I'm getting so cramped, lying flat like this. I want to sit up!'

'R-r-r-r-r-r!' snored Lou and Dan. Julian felt that surely it would be all right to sit up now that the men were obviously asleep. So he sat up cautiously, stretching himself with pleasure.
