Allan and Reggie began to look intent.

'There's Rob coming forward,' said Marjorie softly.

The Highlander touched his cap respectfully.

'I do not think we can pe landing at ta Corrachin Caves to-night, sir,' he said civilly but firmly; 'ta wind iss north-west and ta current iss running ferry strong, sir. We wass thinking it would pe too dangerous.'

'Tut, tut,' said Mr. Stewart; 'we're not going to be so timid as all that, Rob. Just think of some of the days when we have landed, man.'

'But Duncan and I was thinking that it wass a ferry tangerous sea to-day, sir, ferry tangerous indeed, and we will pe afraid for ta ladies, sir, and for ta young ladies and gentlemen.'

'Nonsense, man,' returned Mr. Stewart; 'call this a heavy sea? I never saw a better sea in my life. Tell Duncan to put her head south-east by south.'

But Duncan had taken the helm, and the vessel lay unexpectedly against the wind.

'It iss ta cross currents, sir,' said Rob. 'Yo-ho there! Slack the main-sheet!' and the boys were easing off the rope before they had realised what they were about.

The vessel gave a plunge or two and then steadied herself, Duncan standing with a grim face at the wheel.
