early and full day's work."

"You are jesting with me," protested Mlle. Nadiboff, indignantly.

"Take my arm, then, if you will," requested M. Lemaire. "We will stroll
about, and we shall see if your eyes are keen enough to discover your
young submarine captain."

The young woman defiantly accepted the challenge. By the time that
they had strolled around the ballroom scarlet spots glowed in her cheeks.
In either eye a tear of anger glistened behind the lash.

"Are you satisfied?" murmured M. Lemaire, in a low voice.

"I fear that I shall have to teach the young cub a lesson or two in the
art of showing devotion to a woman's wishes," Mlle. Nadiboff answered,
tremulously.

"Shall we walk in the grounds?"

"I beg you to take me out into the air," replied the young woman.

"Yes, it will be better," whispered her companion, cruelly. "Your face

And that shall be quickly, too!"

"If you do not succeed, Sara," retorted the man, "then sterner measures
will have to be tried. This youthful Benson may even have to lose his
life in the attempt that must be made, at all hazards, to wrest from him
a set of drawings of the boat he commands, and a description of all her
working parts, and all the secrets of managing the boat!"

"If he could hear you, he would be charmed with the outlook," muttered
the young woman, shrugging her shoulders.

"Sara, do you comprehend the situation altogether? The Pollard type of
submarine boat is now the most formidable and dangerous in the
world--and only the United States Government can buy boats from the
makers! Any country in the world that goes to war with the United
States must be beaten unless that country knows how t
