In an hour's time he was round again, and stood awhile at the corner of the square. The tripod fire was burning as fiercely as ever, and gave light enough to show Jones—fast asleep! Jack, however, was awake, and stood there, with bristling hair, ready to guard his master.

'Good old Jack!' said the policeman, as he patted the dog's head, and Jack yawned, stretched his legs, and lay down again.

'And he calls himself a light sleeper!' said the policeman, looking at the snoring Jones, who leant back with his arms folded, and his eyes shut.

'It would be a bit of a joke to make off with his lantern and ropes,' said the policeman to himself; 'it might teach him not to be so bumptious about his light sleeping.'

The idea was irresistible, for the policeman was young, and loved a joke. 'I'll do it!' he said at last, and, as he spoke, he went towards Jones's shelter. Jack—faithful Jack—looked up suspiciously, but the policeman said, briskly, 'It's all right, Jack; your master knows me'—and Jack lay down again, feeling perhaps that a policeman could do no harm.

The next time the policeman passed the square he roused the still-sleeping Jones. 'Wake up, Jones,' he said; 'the men will be here directly, and they must not find you sleeping.'

'I only just closed my eyes,' said Jones, drowsily. He sat up, however, and the next minute exclaimed loudly: 'Hallo! who has been here? Thieves! my lantern is gone and the coil of new rope! I'm ruined, I tell you! I shall never get another night job!'

'Gone?' said the policeman, feigning astonishment. 'Surely not. You are too light a sleeper for any one to take your things without you knowing it, you know.'

'I'm ruined!' repeated the wretched Jones.

'Here, I will have a look with my bull's-eye,' said the policeman, thinking the joke had gone far enough. 'Why, here's the lantern—oh! and the rope, too—hid under these planks,' he called out, after a minute's search.
