Their generous dinner disposed of, Vasco suggested that they immediately begin the exploration of the old city. This was agreed to by the others, and under Juan's guidance they at once made their way into the dense jungle which had grown up about the ruins.

Neither of the Panama boys was very romantic in disposition, but Vasco could not help thinking of the pirates of whom Harlan had told,—how they had trod this very ground, and how back and forth Spaniards and buccaneers had swept in bloody battle. All the military ardour which had been born in his breast was aroused, and he even caught himself wishing that he had been there to help defend the city. Little did he realize how much less enchanting was the experience than the story.

It is not possible to describe all that the boys saw. As they wandered back and forth they imagined that here was a market-place, and there was the residence of some rich old Spanish trader. Over yonder was all that remained of a bishop's palace, and near by may have been the governor's abode.

The old cathedral was easily identified by the tower which still stands. Within its walls the boys went and gazed with awe upon the ancient altar on which Pizarro, the adventurous explorer and conqueror, had left an offering to the Holy Virgin before starting on his voyage to Peru.

Time passed swiftly, however, and it was Enrique who discovered that the sun was fast setting.

"We must soon be starting," he said to Vasco, "if we are to get home before dark."

Harlan, who overheard what Enrique said, was anxious to start immediately, for he knew his mother would be worried if he were late.

So bidding Juan good-bye and thanking him profusely for his kindness to them, the boys took up their homeward march across the old bridge and along the coast. Not so much time was spent on the way as in the morning, for now they were intent only on getting home.

The boat was found safely fast where they had left it, and, quickly spreading the sail, they were soon speeding across the blue waters of the bay. The sail was a delightful one, the cool breeze fanning their cheeks while the slanting rays of the sun cast a glory over the scene which subdued their boyish spirits and filled them with awe as they gazed about them.
