Rilla, still solemn, nodded. “Ye-ah,” she said, “an’ I’m tarnal sartin I don’ know what to do with yo’, bein’ as yer boat’s wrecked. Grand-dad’ll be back by noon and it’s most that now.” A swift glance at the sun had told Rilla the time. “Yo’ll have to hide in Treasure Cave, that’s what! I can’t come to see yo’ thar; ’twouldn’t be honest to Grand-dad; but I’ll let down a basket of grub on a rope. Then, when Cap’n Barney comes in from the fishin’ shoals where he goes every day I’ll hail him an’ tell him to take yo’ to town. He don’ mind city folks the way Grand-dad does.”

As she talked, Rilla led the way along the shore and paused at the foot of the perilous cliff above which towered the lighthouse.

“Thar’s a sail cloth in the cave as yo’ can wrap up in and keep warm,” she said. Then she pointed out the steep trail.

The lad looked at it and secretly wondered if he could make it. Then, turning, he held out his right hand, his cap in the other, as he said earnestly: “Miss Muriel Storm, I thank you for everything.” Then he started to climb. The girl watched him anxiously. “Steady there!” she cautioned. “Keep an even keel.”

The lad reached the ledge in safety and turned to wave his cap; then, stooping, he entered the cave, and none too soon, for, right at that very moment, a stentorian voice from the top of the cliff called, “Rilly gal, where be ye?”

“Comin’, Grand-dad!” the girl replied. Then she raced along the strip of pebbly beach, the dog at her heels.

Rilla’s heart was pounding with tumultuous excitement. How she wished that she could go to her grandfather and tell him the whole truth, but she did not dare.

CHAPTER IV.
A SHIPWRECKED MARINER.

Cap’n Ezra Bassett was removing his rubber boots when Rilla entered the room. The tea kettle was singing cheerily on the stove. She had refilled it when she had made tea for Gene.

Again the old man noticed the flushed, excited appearance of the girl. “Rilla gal,” he said as he tugged at one boot, “what in tarnation have you got stowed away in that cave o’ yourn that you’re so plumb interested in? I swan I can’t figger it out. Maybe I’d better take a cruise down that way and be inspectin’ below decks.”
