A MYSTERIOUS DISAPPEARANCE

At the center of a circular bay, forming a perfect horseshoe with a sandy beach at its center and a rocky cliff on either side, two girls were fishing for shrimps. The taller of the two, a curly-haired, red-cheeked girl of eighteen, was rowing. The other, short and rather chubby, now and again lifted a pocket net of wire-screening, and, shaking a score or more of slimy, snapping creatures into one corner of it, gave a dexterous twist and neatly dropped the squirming mass into a tin bucket.

Both girls had the clear, ruddy complexion which comes from clean living and frequent sallies into the out-of-doors. Lucile Tucker, the tall one of curly hair, was by nature a student; her cousin, Marian Norton, had been born for action and adventure, and was something of an artist as well.

"Look!" exclaimed Lucile suddenly. "What's that out at the entrance of the bay—a bit of drift or a seal?"

"Might be a seal. Watch it bob. It moves, I'd say."

Without further comment Lucile lifted a light rifle from the bow and passed it to her cousin.

Marian stood with one knee braced on the seat and steadied herself for a shot at the object which continued to rise and fall with the low roll of the sea.

Born and reared at Nome on the barren tundra of Alaska, Marian had hunted rabbits, ptarmigan and even caribou and white wolves with her father in her early teens. She was as steady and sure a shot as most boys of her age.

"Boat rocks so," she grumbled. "More waves out there, too. Watch the thing bob!"

"It's gone under!"
