Cautiously, with the large bundle under her arm, she returned to Dodge Hall and almost sneaked into her own home and up-stairs to her room. She locked the door and hastily unwrapped the bundle taking out a tattered suit and the other things, holding them up and laughing gleefully as she took off her own pretty clothes and donned these hideous garments.

Quickly she completed her change of costume and outward character. As she surveyed herself in the dainty mirror of her dressing-table she laughed again at the incongruity of her pretty boudoir and the rough men's clothes she was wearing. Deftly she arranged her hair so that her hat would cover it. She picked a black mustache from the table and stuck it on her soft upper lip. It tickled and she made a wry face over it. Then she hunted up a cigarette from the bundle which she had brought in, lighted it and stuck it in the corner of her mouth, letting it droop jauntily. It made her cough tremendously and she threw it away.

Finally she went to the door and down-stairs. No one was about. She opened the door and gazed around. All was quiet. It was a new role for her, but, with a bold front, she went out and passed down to the gate of the grounds, pulling her hat down over her eyes and assuming a tough swagger.

Only a few minutes before, down in the submarine harbor, the officers of the board of foreign agents had been grouped about Del Mar, who had entered and taken his place at their head, very angry over the failure to cut the cable. As they concluded their hasty conference, he wrote a message on a slip of paper.

"Take this to our wireless station," he ordered, handing it to one of the men.

The man took it, rose, and went to a wardrobe from which he extracted one of the submarine suits. With the message in his hand, he went out of the room, buckling on the suit.

A few minutes later the messenger in the submarine suit bobbed up out of the water, near the promontory, and climbed slowly over the rocks toward a crevice, where he began to take off the diving outfit.

Having finished, he hid the suit among the rocks and then went along to the little river, carefully skirting its banks into the ravine in which were the falls and the wireless cave.

In her disguise, Elaine had made her way by a sort of instinct along the shore to the rocky promontory where we had discovered the message in the tin tube in the water.

Something, she knew not what, was going on about there, and she reasoned that it was not all over yet. She was right. As she looked about keenly she did see something, and she hid among the rocks. It was a man, all dripping, in an outlandish helmet and suit.
