“But what of that?” asked Tom.

“There is some one in that tree,” explained Jim. “That is why, as you will notice, the birds alight on the other trees, but never upon that one.”

Observing for a continuous period the actions of the birds their maneuvers seemed to confirm Jim’s theory.

“This then,” determined Jim, “is our place of observation when it comes to the surrendering of the Senorita and the paying of the ransom. We cannot be seen here, but can get quickly into action and upon the scene if there is need.”

“We have the place of ambush,” said Berwick, “and the next thing to find out, if we can, is, when the villains are to complete the transaction.”

“For that purpose I am going to attempt to hunt out the senor, and try to secure, if possible, an interview with him.”

Jim had noticed that a faintly marked trail led inland from the shore, and a short way up the nearest hill was seen a low bungalow with out-buildings which Jim concluded was a way-house or inn, and the likely stopping place of the Senor.

“What are we to do?” asked Tom.

“You four remain here on guard and fire two shots in quick succession if I am wanted.”

Saying this, Jim strode away in the direction of the foot hills, but sheltered the while from observation by the forest and underbrush.
