ly up it. The
others waited, watching him as he surveyed the apparently deserted
place from the cross-piece of the pole. By and by he came down.

"It's there, Darry," he said confidently. "Your big idea was all to
the good. That folding wireless staff you use on the _Marigold_ is
repeated right on the top of that tower. When they use the sending set
they raise the staff with the antenna and--there you have it."

"Oh! Then she's in the tower!" cried Amy.

"At least, she was in the tower if she sent her message from this
station," agreed Darry.

"How shall we find out--how shall we?" cried Amy, excitedly.

"If Mr. Stratford is quite sure that he sees the aerials upon that
roof, then I am going to get the tower door open somehow," declared
Jessie, with her usual determination.

"It is there, Miss Jessie," Mark assured her.

"Come on, Henrietta," said Jessie, helping the little girl to jump
down from the car. "We are going to find your Cousin Bertha if she is

tower building and you shout for Bertha just as hard as you can shout.
She will know your voice if she doesn't know you in your new dress,"
and she smiled down at the little girl clinging to her hand.

this to demand of the party of young folks from Roselawn what they
wanted. As Jessie Norwood walked up the lane, with little Henrietta by
the hand and followed by Darrington Drew, she saw no person at any
window or door.

The tower might have been abandoned years before, as far as appearance
went. But Mark Stratford's discovery seemed to make it plain that the
tower was sometimes in use.

Jessie noted that the tower stood on a knoll behind the house from
which vantage the race track some quarter of a mile away might be
seen. With good field glasses one might stand in the second story of
the tower and see the horses running on the track. Then, if there was
a sending radio set in the tower, the reports of races could be
broadcasted in secret code to sets tuned to the one in the tower.

Of course, if the radio instrument was so illegally used, it was on
