When his two best friends had departed, Captain Barney sat long in front of his shack. He wondered what was to come of it all, but only the future could reveal that.

CHAPTER IX.
A FIRST LETTER.

Muriel had almost forgotten the banded box of foreign appearance which she had in her Treasure Cave. So many things of unusual interest had occurred of late that even so wonderful a box had taken a secondary place in her thoughts.

That afternoon Captain Ezra devoted to polishing the lamp, a task he would not permit Rilla to share, saying that peeling potatoes and the like was her part of the drudgery, and, as he never helped her with that, neither should she help with the lamp.

Muriel did not insist, for she believed that her grand-dad took a great deal of pride in tending to the big light all by himself. “I reckon he’d think he was gettin’ old if he had to be helped,” the girl soliloquized as she walked along the top of the bluff, the dog at her side.

They descended the trail toward that part of the beach where she had first seen the lad. For a time she stood silently gazing down at the spot where he had been on that never to be forgotten day. Suddenly she laughed aloud. Stooping, she patted the head of her long-haired companion.

“Shagsie, ol’ dog,” she chuckled gleefully, “yo’ wouldn’t be eatin’ Gene Beavers up even when I tol’ yo’ to, would yo’ now?” Then merrily she added: “I’ll tell yo’ a secret, ol’ dog, if yo’ won’t be tellin’ it.” Then she whispered into the long shaggy ear: “I reckon I’m glad now that yo’ wouldn’t.” Then, springing up, she scrambled down the rocks and ran along the narrow pebbly beach, the dog racing and barking at her heels. When they were just below the lighthouse Rilla paused and looked up at the small entrance to her cave.

“Shags,” she suggested, “let’s take another look at the treasure.” Together they slowly ascended the perilously steep cliff where one unused to climbing could barely have found a foothold.

When the cave was reached Rilla uttered a little cry of eagerness, for under one of the straps on the box was a folded bit of paper.

Opening it, she looked at it, her cheeks flushed, her eyes glowing.
