'Some people have more in them than they make a show of,' she said.

'Perhaps you don't understand that kind of thing, though.'

Harry did not chance to have a reply ready, but he observed to Reggie afterwards that it was a pity Marjorie seemed to be a quick-tempered kind of a girl.

'Here we are,' said Allan, pausing beneath a great overhanging archway, and speaking loudly so as to be heard above the din; for the waves and the clamouring of the birds made a noise which was almost deafening.

'Can we go in?' asked Gerald.

'Of course we can. There's no danger except in a westerly gale. It's dark after you get in a little way.'

The young people scrambled and slipped over the sea-weed at the mouth of the cave, and presently found themselves standing on a floor of light-coloured sand, strewn with sh.e.l.ls and sea-drift. The sides of the cave were black and shiny with wet, and water dripped slowly from the roof.

'Is this where the smugglers used to come?' asked Gerald in an awed tone.

'Yes,' replied Allan; 'the schooners used to sail under the rocks on moonlight nights when the tide was high, and the cargo was stored in the caves until the people came secretly to take it away. It was very dangerous work sometimes, for if a storm comes from the west the caves are often flooded.'

The light which glimmered under the archway did not penetrate far, and the young people were soon in total darkness. The air was damp and chilly. Strange draughts crossed each other from unexpected quarters, and the water dripping from overhead, awoke weird echoes which seemed to be repeated among far-reaching clefts and pa.s.sages.

'Strike a light, Hamish,' said Allan, 'and let them see what kind of a place they're in.'

The match spluttered and blazed, revealing dark rocks gleaming with wet and the black openings to what appeared to be a series of underground pa.s.sages branching off from the main one.

'The caves are all connected with one another,' explained Allan, 'and have separate openings to the sea. Light up again, Hamish; strike two this time, and they'll get a better idea.'

Again there was a splutter, and the flare revealed strange shifting shadows among the rocks, and a circle of faces that looked unnaturally white in the surrounding darkness.

Reggie's eyes were the sharpest.

'Hullo!' he exclaimed, 'there's something in that pa.s.sage. What can it be?'

All crowded to examine the mysterious object, and the light flickered upon a pile of kegs and bales lying half-concealed behind a corner of rock.

'Smugglers!' declared Marjorie.

'Looks like it,' said Allan, as Hamish struck fresh matches and the others crowded round, giving utterance to ohs! and ahs! of excitement.

'They're at their old trade again,' said Allan, examining the barrels; 'I wonder what Pater will say to this?'

'That's the last match, Allan,' said Hamish, as the light flickered out.

The darkness seemed to come down like a weight, and the young people found themselves groping for each other's hands.

'We had better make the best of our way out of this,' said Allan. 'Try to move quietly, for we don't know who might be about. Help Tricksy, Hamish; I think she's by you, and here, Tricksy, give me your other hand.'

They groped their way towards the entrance, and soon were in the strong sunshine at the mouth of the caves.

'Well,' said Allan, 'that was an adventure;' and they looked at one another with varying expressions.

'Do you think they may have had anything to do with the robbery?' said Marjorie.

'Shouldn't wonder,' replied Allan. 'Anyhow, we'll see what Pater says.'

'In the meanwhile,' said Marjorie, 'we had better be quick; the breakers are close under the rocks, and we're almost cut off already.'

A stream of foaming, angry-looking water was running up into a hollow on the sh.o.r.e, and the young folk could only escape by jumping on to a stone in the middle of the flood, and from thence to the other side.

'Jump, Tricksy,' cried Reggie half impatiently, as his little sister hesitated.

Tricksy, who was pale and overwrought, sprang, but fell short and plunged overhead in the water.

Instantly two or three were in the flood, trying to prevent her being swept out to sea.

Allan secured her; and gasping, struggling, with water running over her face, Tricksy was pulled on to dry land.

'It isn't so very bad, is it, Tricksy?' inquired Reggie, in a tone of somewhat forced cheerfulness; 'what a thing to do, to jump in when you're told to jump over!'

Tricksy tried to smile; a miserable attempt, for her teeth chattered and her lips were blue with the cold.

'Run to Rob MacLean's cottage, Reggie,' said Hamish, throwing off his coat and wrapping it round Tricksy; 'ask him to lend us his pony, and we'll take Tricksy to Corranmore; it's nearer than your house.'

With Hamish running by her side and holding her on to the pony, Tricksy was not long in reaching Corranmore, and when the others arrived she was already in bed, with Mrs. MacGregor beside her; the little girl drinking hot milk and trying to restrain the tears that _would_ roll down her cheeks, even when she forced herself to laugh.

'Feeling better, Tricksy?' asked Reggie apprehensively.

'She has had a nasty fall,' said Mrs. MacGregor somewhat reproachfully, 'and we may be thankful it is not any worse. She can't possibly go home to-night; you had better tell your parents that she is safe with us.'

A look of relief overspread Tricksy's tired features.

'Oh, you _are_ a dear,' she exclaimed, springing up and throwing her arms round Mrs. MacGregor's neck, forgetting that the lady had once said that Tricksy Stewart was a spoilt little girl. 'Hooray, I'll sleep with Marjorie and we can talk about what we have seen to-day!'

CHAPTER VII

THE SIEGE

'No, Mr. Allan,' Duncan was declaring, 'if I wa.s.s you, I would not pe telling the laird whateffer; it can do no good pringing honest folk into trouble.'

'But they are not honest folk if they're smugglers,' interposed Reggie, who had been listening to the conversation without joining in.

A peculiar expression flitted across Duncan's face.

'Well, but, Mr. Allan,' he maintained; 'I'm just telling you, that it will pe petter if you will not pe telling the laird; you will only pe meking trouble in the island and will pe doing no good at ahl, at ahl.'

'But what if it was they who robbed the post-office?' said Allan.

'Robbed the post-office, Mr. Allan!' cried Duncan; 'what will they pe doing that for? Not them, Mr. Allan! So do not pe meking trouble by telling the laird----'
