A NIGHT ALARM

Mary Nestor spoke with such earnestness, and her action in catching
hold of Tom's arm to enjoin silence was so pronounced that, though he
had at first regarded the matter in the light of a joke, he soon
thought otherwise. He glanced from the girl's face to the dense
underbrush on either side of the woodland path.

"What is it, Mary?" he asked in a whisper.

"I don't just know. I heard whispering, and thought it was the rustling
of the leaves of the trees. Then someone spoke your name quite loudly.
Didn't you hear it?"

Tom shook his head in negation.

"It may be Ned and his friend," he whispered, his lips close to Mary's
ear.

"I think not," was her answer. "Listen; there it is again."

Distinctly then, Tom heard, from some opening in the screen of bushes,
his own name spoken. "Did you hear it?" asked Mary, barely forming the
words with her lips. But Tom could read their motion.

"Yes," he nodded. Then, motioning to Mary to remain where she was, he
stepped forward, taking care to tread only on grassy places where there
were no little twigs or branches to break and betray his presence. He
was working his way toward the sound of the unseen voice.

There was a sudden movement in the bushes, just beyond the spot Tom was
making for. He halted quickly and peered ahead. Mary, too, was looking
on anxiously.

Tom saw the forms of two men, partially concealed by bushes, walking
away from him. The men took no pains to conceal their movements, so Tom
was emboldened to advance with less caution. He hurried to where he
could get a good view, and, at the sight of one of the men, he uttered
an exclamation.

"What is it?" asked Mary, who was now at his side. She had seen that
Tom had thrown aside caution, and she had come up to join him.

"That man--I know him!" the young inventor exclaimed. "It is
Feldman--the one who wanted to be changed from the trip-hammer to the
airship department. But who is that with him?"

As Tom spoke the other turned, and at the sight of his face Mary Nestor
said:

"He looks like a Frenchman, with that little mustache and imperial."

"So he is!" exclaimed Tom, in a hoarse whisper. "He must be the
Frenchman that Eradicate spoke about. I wonder what this can mean? I
didn't know Feldman had left the shop."

"You may know what you're talking about, but I don't, Tom," said Mary,
with a smile at her companion. "Are they friends of yours?"

"Hardly," spoke the young
