"Well, boys, what are your plans?" demanded Ben, as—after the rugged fellow had been introduced to Mrs. Chester, a sweet-faced old lady, and Mr. Chester, a fine-looking, gray-haired man of about fifty—he and the boys sat in the garage discussing the African outfit.

"We hardly know now," replied Frank, and then in a few words he described Lathrop's letter and its contents.

"Wherever that boy is there's bound to be doings," remarked Ben, sententiously, when the young leader had finished. "Down in Florida when he wasn't tumbling into alligators' mouths or getting bit by serpents he was allers up to some mischief—you mark my words there's something in the wind now."

The boys talked late and long that night over the letter and what possible plan Mr. Barr, the ivory importer, could have to discuss that would be of interest to them, but they were able to arrive at no definite conclusion except that there was nothing to be done about it till morning.

As for Ben with his usual philosophic attitude toward mysteries, he filled his pipe and silently smoked. To those of our readers who have not met Ben this phase of his character may seem inexplicable, but to the boys Ben's passive acceptance of any situation had become quite familiar. Ever since they had rescued the rugged old adventurer from a marooned treasure-mine in Nicaragua and he had shared their strange adventures in Florida on the Chapin Rescue Expedition, the old man had become as much a part of their necessary equipment as the Golden Eagle itself. He had arrived that night in response to a telegraphed request to his cottage at Amityville on Long Island, where he cultivated an extensive farm—also part of the Quesal ruby profits—and devoted himself to fishing and hunting.

'The Boys' mere word, however, that they were off to Africa had been sufficient to arouse the old man's roving instinct and here he was on deck once more as active as a boy and almost as impatient for the start for the Dark Continent. Ben slept at the Chester's home that night and if his dreams were not as populated with visions of elephants, leopards, deer, huge snakes and pigmy savages as theirs it was not any lack of interest in the coming expedition that was responsible for it.
