'What happened?' asked Julien, startled. 'One would think the brute would have remained satisfied with pushing me into the water. But I will make him repent,' he added, in a threatening tone. 'My father will not let him off easily.'

'He doesn't know any better,' said Estelle, gently.

'Spoken like the kind little Missie you are,' said Jack, with a smile. 'But we must not let him do any more mischief, all the same. He did not mean to hit you with the stone. It is a good thing for me that it did no more than graze my head; and for you, Missie, that it was not a larger one.'

'In fact, Jack,' laughed Estelle, with a soft glance at him, 'we have all something to be thankful for—— '

'And that is that we are all here to tell the tale,' added Julien, rising from the folds of his blanket, and beginning to stamp about. 'Thomas also has to be thankful that we are not for the moment able to hand him over to M. le Préfet. I suppose he will have escaped by the time we get out of this.'

It was just this question which was tormenting the mind of the ex-gardener. Would he be able to get out before Jack? He could not imagine where the sailor had taken the children. The dim light of the candle-ends had died out as Jack swam away with Estelle, and Thomas had not as yet discovered the existence of the Treasure Cave. Only an eye accustomed to look for the faint ray of light thrown upon the roof by the glimmer from the lower cave could have detected where to seek the ledge, which it was necessary to climb in order to reach the Treasure Cave. All he could imagine, therefore, was that Jack had known of some other, and probably wider, place of refuge than that on which he himself had sought an escape from the waves. If this were so, it was more than likely that in the attempt to escape as quickly as the tide permitted, an encounter between him and Jack would take place. The bare suggestion excited Thomas uncomfortably. Over and over again did his mind ponder on the best plan to avoid such a meeting. Should he remain where he was till the sailor and the child had gone? But how would he be able to judge of their departure? It was totally dark, and as Jack must be in as drenched a condition as himself, no matches he might carry about him could be ignited. The escape must be made in the dark.

No, Thomas could run no risks of that sort. He made up his mind that as soon as his ear—trained by a life-long residence on a rocky coast—told him the sea was leaving the Mermaid's Cave, he would descend from his narrow perch, and follow the retreating tide. There would be light enough in the Cave of the Silver Sand. If an encounter must take place before he could get away from the caves, he preferred it should take place in daylight. As soon, therefore, as the lapping of the waves grew faint and died softly away, he felt his way down from the ledge of rock, and round by the walls to the Rift.

Barely had he waded through it when he heard voices behind him. A cold shiver ran down his back at the sound. Jack must be approaching with the children. Julien had been saved, then, for it was the voice of the French boy he heard speaking. The whole party would be upon him soon. With some anxiety, Thomas looked at the sea. Rapidly as it was going down, there was no chance that it would leave the cave in time for him to make his escape without being seen. There were rocks scattered about on all sides, however, which offered him a place of concealment, and he was not slow to avail himself of their shelter. Barely had he thrown himself behind one when Jack and his charges appeared.

'And when do you think it will be?' he heard Estelle saying, as she held Jack's hand, and walked soberly at his side.

'I can't say exactly, Missie,' was the reply. 'Maybe in a week or a fortnight.'
