ace with the pretty young girl in whom he had taken such an interest.
Her recent sobs and cries still haunted his heart, and he felt certain
she must be in great sorrow over something.

He commenced climbing. While his boast about being equal to any monkey
that ever lived among the treetops may have been a bit of an
exaggeration, all the same Jack was a very good athlete, and especially
with regard to feats on the parallel bars or the ladders in a gymnasium.

He made his way nimbly upward, with Tom's eyes following every movement.
It seemed an easy task for the climber. Just what he would discover when
he had gained the open window was another question.

The light still remained, for which both boys felt glad. It afforded
Jack a goal which he was striving to gain; and it told Tom further down
that the inmate of the upper room was awake and still moving about,
though her sobs had ceased.

Once Tom fancied he heard something stirring back of the house. He hoped
it might not prove to be a servant attached to the Potzfeldt place or an
attendant who had charge of the pigeon loft.

Jack was almost up now. He had only to cover another yard of space when
he could look into the room of the lighted window. That was where fresh
peril must lie, because his figure would be outlined in silhouette, and
any one moving about the grounds might discover that uninvited guests
had arrived.

Tom wished he had told his chum to insist that the light be immediately
extinguished, if, as they believed, it proved to be Bessie who occupied
that room. He hoped his chum would think of it without being told.

There! At last Jack had arrived, and without accident! Now he was
cautiously thrusting his head up a little, to peer within.

Tom held his breath. So much depended on what would follow Jack's
betrayal of his presence.

"Tell her to put out the light, first of all, Jack!" Tom gently called
out, using both hands as a megaphone to carry the sounds.

It seemed that he must have been heard, and his directions understood,
for immediately there was another movement above, after which the
illumination ceased, as though Bessie had blown out the lamp.

Tom breathed easier, though he still continued to look, and wonder how
his chum was going to get the girl safely down from her elevated
apartment. Jack was not so fertile in expedients as his chum, and many
times depended on Tom to suggest ways and means.

While Tom was still waiting, and hoping
