“Well, that beats shooting the chutes, for taking your breath away,” remarked Harry as the party strolled along under a palm-bordered avenue on their way to the hotel where they were to lunch. The dripping crew of the bonga followed them carrying the boys’ smart, new baggage on their heads.

The Hotel Grand Central was a long building with a red-tiled roof and the invariable patio in the center off which the room opened. The boys were delighted with the place. In the middle of the patio, in a grove of tropical plants, a cool fountain plashed and several gaudy macaws were clambering about in the branches of the glistening greenery. The hot dusty street outside with its glaring sun and blazing iron roofs seemed miles away.

As they were about to turn into the sala, in which their meal was to be served, a man bustled out and almost collided with them. It was General Rogero.

“Ah, Señor, we seem fated to encounter each other to-day,” he exclaimed with a flash of irritation as his eyes met Mr. Chester’s.

The next moment he had started back with a quick: “peste!” as his dark gaze fell on the boys.

“Why!” exclaimed Harry, “that’s the fellow who came down on the ship. The man who said he was a diamond salesman and that he had a lot of stones in that black bag! Do you know him, father?”

“Know him?” repeated Mr. Chester in a puzzled tone as Rogero whisked scowling out of sight into an adjoining room.

“He was a mysterious sort of cuss,” chimed in Frank, “kept to himself all the way down and had his meals in his cabin.”

“Perhaps he had a good reason to,” smiled Mr. Chester; “your diamond salesman is General Rogero of the president’s army.”

As he spoke and the two boys fairly gasped in astonishment at this sudden revelation of the true character of the man with the black bag, Billy Barnes came hurrying up.
