He had too much brain—too fine a nerve-quality to face the forest alone. Bonpland made good all that he lacked. He used to call Bonpland his "Treasure." And surely such a friend is a treasure, indeed. Bonpland was a linguist, as most of the Swiss are. He was a mountain-climber, and had been a soldier and a sailor, and he knew enough of literature and science, so he was an interesting companion.
He was small in stature, lithe, immensely strong, absolutely fearless, and had left behind him neither family nor friends to mourn his loss. To Humboldt he was guide, teacher, protector and friend. Bonpland was the soul of unselfishness.
Perhaps a certain quality of man attracts a certain quality of friend—I really am not sure. But this I know, that while Alexander von Humboldt had few personal friends, he always had just those which his nature required—his friends were hands, feet, eyes and ears for him, to quote his own words. This voyage on the "Pizarro" occupied five years. The travelers visited Teneriffe, Cuba, Mexico, and skirted the coast of South America, making many little journeys inland.
They climbed mountains that had never been scaled before; they ascended rivers where no white man had ever been, and pushed their way through jungle and forest to visit savage tribes who fled before them in terror thinking they were gods. On the return trip they visited the United States; spent some weeks in Washington, where they were the guests of the President, Thomas Jefferson. A firm friendship sprang up between Humboldt and Jefferson: they were both freethinkers, and when Humboldt recorded in his journal that Jefferson was by far the greatest man living in America, he not only recorded his personal conviction, but he spoke the truth.
And as if not to be outdone, although he did not then know what Humboldt had said of him, Jefferson declared that Alexander von Humboldt was the greatest man he ever saw.
Most of the vast number of rare specimens and natural-history curiosities gathered by Humboldt and Bonpland were placed on a homeward-bound ship that sailed from South America. This ship was lost and all the precious and priceless cargo went for naught. Had Humboldt and his companion sailed on this ship, as they had at first intended, instead of returning by way of the United States, the world would not have known the name of Alexander von Humboldt.
But Fate for once was kind—the world had great need of him.
hen Humboldt landed at Bordeaux in August, in Eighteen Hundred Four, after his five-year journey, he immediately set out to visit his brother, who was then German Ambassador at Rome. We can imagine that it was a most joyous meeting.
Of it William said: "I could not recognize him for my tears—but beside this he seemed to have grown in stature and was as brown as a Malay. Was he really my brother? Ah, the hand was the hand of Esau, but when he spoke, it was the same kind, gentle, loving voice—the voice of my brother."
