“Do you really think we could run the thing down, and find the party at the other end of the kite string?” demanded Amos, at once interested.

“I should say there was a fair chance,” declared the ranch boy, who figured things out from force of habit on every occasion. “In the first place you know that a kite must always go up directly against the wind. There can be no compromise about that.”

“Sure thing,” agreed Amos, already intensely interested.

“Well, it’s easy to gauge the direction of the wind, and, after noticing how high the kite must be, we can figure about how far away the man would be standing who held the other end of the cord.”

Jack’s reasoning was so simple and yet so convincing that the other immediately fell into his way of thinking.

“Let’s do it, Jack!” he exclaimed enthusiastically.

“I take it you mean to try and look up the kite-flyer, eh, Amos?”

“Yes, and give him a little scare in the bargain. That old kite with its red lights has hung up there long enough.”

“It’s probably fulfilled its mission,” suggested Jack, “and conveyed the information that it was planned to send. But I’m curious enough to want to find out whether my theory was sound or not.”

“Then you say go, do you, Jack?”
