'Now!' burst from the lips of the gazers as the lofty cliffs came in view, with the waves tumbling at their base.

Captain Redwood had issued orders to slacken speed, and as the vessel steamed slowly past, a fine view was obtained of bold masses of rock and the black openings to the caves, with the startled birds rising in clouds and screaming.

'If all stories are true, the caves are still sometimes put to their old uses,' observed Mrs. MacGregor as the Heroic's engines throbbed through the smooth swell of the water; 'for all we know, the most thrilling adventures may be taking place there.'

'A score of men might lie in hiding without discovering one another's presence,' said the laird; 'the caves form a regular network, and stretch a long way underground. The entire headland is said to be honeycombed with them——'

'Hullo, good people!' cried a soft little voice from overhead, followed by a triumphant laugh.

Every one looked round, and half-way up the mast Tricksy was discovered, who having become annoyed at her desertion by Lieutenant Jones, was indulging in an exploring expedition on her own account. Her little round face smiled mischievously from between a large white hat and tumbled frock, and she sat swinging her heels in perfect contentment.

Jim Macdonnell's duties having brought him to the quarter-deck at this moment, the captain made him a sign almost without pausing in the sentence which he was addressing to Mrs. Stewart.

The sailor climbed into the rigging and removed Tricksy very gently from her perch, tucked her under one arm with her head hanging in front and her heels behind, slid down the ropes and deposited the little girl on the deck.

Tricksy stood and looked at every one in speechless wrath. Her dignity, being as great as her anger, prevented her from giving way to an outburst before she should have discovered who deserved it most.

Lieutenant Jones crossed over to her.
