Another twenty minutes elapsed while the Scouts grew increasingly impatient.

Finally, the one for whom they waited, arrived at the dock. A handsome woman of forty, dressed in a white linen suit, came hurriedly to the sled-boat. Porters carried her luggage, and a number of boxes.

“Gosh, she must be the wife of an official or something!” Warwick whispered to Jack. “She had her nerve holding us up nearly an hour!”

“Quiet!” the other warned him. “You want her to hear?”

The woman spoke briefly with the operator of the sled-boat, whose name the Scouts now knew to be Haredia. They conversed so rapidly in Spanish that Jack could not understand, despite some knowledge of the language. However, he saw the pair glance twice in the direction of the boat, and had an uneasy feeling that the Scout party was under discussion.

Presently, the woman came aboard, accepting the chair which Mr. Livingston offered her. She scrutinized each of the Scouts and sat down without mentioning her name.

“I’m George Livingston,” the Scout leader introduced himself, intending to be friendly.

A roar of the powerful boat motor drowned out his words. The woman merely inclined her head slightly in acknowledgement of the introduction and made no answer.

The Scouts settled back into their chairs expectantly. A great fountain of spray was thrown up as the boat glided smoothly over the water on her long runners.

“This is great!” War cried, thoroughly enjoying himself. “Just like a toboggan!”
