The fifth youth in the crowd was a tall, lank individual of about Mark’s age, with a white freckled face and reddish hair. His name was Jacob Hockley, and he was the son of a millionaire lumber dealer of Pennsylvania. His manner was varied, at times exceedingly “bossy,” as the others termed it, and then again exceedingly sour and morose. The latter mood had won for him the nickname of “Glummy” or “Jake the Glum,” and although he objected strenuously to being called such a name, yet it clung to him in spite of everything. Hockley had plenty of money and spent it freely, but even this failed to make him any close friendships. “Glummy thinks money is everything,” said Mark in speaking of the matter one day. “But sooner or later he is bound to learn that there are some things that even money can’t buy.” And Mark was right. True friendship is never a matter of dollars and cents. For several years all these boys had attended a boarding academy located among the hills of New Hampshire. Lakeview Academy, as it was called, was presided over by Professor Amos Strong, a kindly and well educated gentleman, who had in years gone by been a great traveler and hunter. Professor Strong had often told the lads about his hunting expeditions in various parts of the globe, and through these stories a plan had originated to visit Central and South America, the expedition to be under the personal supervision of the professor himself. At first Professor Strong could not see his way clear to leaving the academy, but a fire came and destroyed the place, and at the same time the professor’s brother, also a teacher, left the faculty of Harvard. It was then arranged that the school building should be rebuilt under the directions of the brother, who was afterward to assume control of the institution. This would give Professor Strong the liberty he desired and which he, in secret, greatly craved. For many years a wanderer on the face of the earth, binding himself down to steady teaching had proved rather irksome to him. After a good deal of discussion it was decided that the party of six should first visit Venezuela, and in the first volume of this series, entitled “Lost on the Orinoco,” I related the particulars of the journey from New York to La Guayra, the nearest seaport, and told of the sight-seeing and adventures while visiting Caracas, the capital, Macuto, the fashionable summer resort, the great Gulf of Maracaibo, and other points of interest, including cocoa and coffee plantations and gold and silver mines, and also a never-to-be-forgotten journey up that immense river, the Orinoco, the second largest stream in South America. The boys had had adventures in plenty, and becoming lost on the Orinoco had almost proved a serious happening for Mark and Frank, who had wandered away in a jungle that seemed to have no end. All of the party had met more than one wild animal, and a squall on Lake Maracaibo had come close to sending them all to the bottom.
