“Yes. It would make an ideal station. But I went all around it. I can’t see the roof, for it is practically flat. And if what I suggested was there, we will have to get above the level of the roof to see it.”
Mark suddenly got out and opened his toolbox. He brought forth a pair of lineman’s climbers.
“Thought I had ’em here. I’ll go up that telegraph 191 pole and see what I can see,” and he began to strap them on.
“Good as gold!” cried Burd admiringly. “You have a head on you, young fellow.”
“Yes,” said Mark dryly. “I was born with it.”
He proceeded to the tall telegraph pole and swarmed quickly 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.
