“I think I shall have to be running along, ladies, if I am to have that ’plane ready for work in the morning,” declared Bill, as they reached the hotel verandah.

“And you really think it will take the yacht from five to seven hours to make the trip through?” asked Polly, anxiously.

“Oh, yes! Even if everything runs smoothly, which it seldom does, you know, where we have to depend upon native labor to drive the mules and tow the boats. Better allow seven hours, at least, I think.”

“And you hope to be here for us at ten?” added Eleanor.

“At ten, unless the engine goes on strike again,” laughed Bill.

“Well, then, you hurry along and forbid a strike, while we go to bed. I’m tired with all the day’s excitement,” said Polly, trying to stifle a yawn.

Thus unceremoniously sent about his business, Bill laughed and lifted his cap. In another minute he was out of sight down the old cobbled street.

Polly and Eleanor found it quite unnecessary to be rocked to sleep that night; and it seemed but a few moments after they fell asleep before a knock on the door of their suite roused them to action. It proved to be a message from Bill, left at the hotel in his passing by to have breakfast. The message told the girls the ’plane was in fine condition for their return trip that morning.

The girls dressed hurriedly and then hastened to the diningroom to breakfast. By nine-thirty they were awaiting their escort who called for them shortly after they came out upon the wide piazza.

As they passed through the ancient old city of Panama they were interested in various sights which Bill pointed out and about which he told the prevalent legends.
