t for one
hour.

They were delighted at the prospect, and laid themselves down on the
grass.

So secure did they feel that they relaxed their watchfulness and
allowed the prisoners to lie down by themselves a little distance away,
yet not so far that they had any chance of escape.

Allen was singing a song of freedom; it was an old French ditty he had
learned and often sung.

He sang, not because his spirits were light, but simply to prevent a
feeling of melancholy overmastering him.

The singing satisfied his captors that he was resigned, and was not
meditating any plan of escape.

In the midst of his song he heard a soft, low voice say:

"Do not speak, but listen."

Baker had fallen asleep, and Allen knew that it was Eben who spoke; but
how the boy got there, or, in fact, where he was, Allen could not
conjecture.

"Here is a knife," said Eben; "I am going to cut the cords which bind
your hands; you can then liberate Baker. When you are both free, keep
still until you hear the cry of the catbird, and then leap to your feet
and run, taking a course direct to the left; the boys are there in
ambush, and you will be safe."

While Eben was speaking he succeeded in cutting the cords, and Allen's
hands were free.

Eben glided away as noiselessly as he came, and Allen woke Baker as

Allen told him all that had been done, and then quietly cut the other's
cords.

Both men were free.

They lay as still as though the cords still bound their bodies.

Allen sang another song in a low, tremulous voice.

Again it had the effect of disarming suspicion.

A bird warbled in a tree, rather strangely for so late at night, but as
one of the men remarked that it was the bird's lookout and not his, no
notice was taken of it.

And then the warbling ceased and the peculiar call of the catbird was
heard.

Instantly the two prisoners were on their feet and making for the wood.

They had got some yards before their movement was noticed.

At once the soldiers seized their guns, and a volley was fired after
the fugitives.

The shots did not reach the mark, and pursuit was commenced.

Allen heard the catbird again and again, and by its sound guided his
footsteps.

The soldiers were close behind and were gaining every minute, but the
Mountain Boys ran plucki
