A young printer wanders around a good deal, seeking and finding work; and seeking again, when necessity commands. N. B. Necessity is a CIRCUMSTANCE; Circumstance is man’s master—and when Circumstance commands, he must obey; he may argue the matter—that is his privilege, just as it is the honorable privilege of a falling body to argue with the attraction of gravitation—but it won’t do any good, he must OBEY. I wandered for ten years, under the guidance and dictatorship of Circumstance, and finally arrived in a city of Iowa, where I worked several months. Among the books that interested me in those days was one about the Amazon. The traveler told an alluring tale of his long voyage up the great river from Para to the sources of the Madeira, through the heart of an enchanted land, a land wastefully rich in tropical wonders, a romantic land where all the birds and flowers and animals were of the museum varieties, and where the alligator and the crocodile and the monkey seemed as much at home as if they were in the Zoo. Also, he told an astonishing tale about COCA, a vegetable product of miraculous powers, asserting that it was so nourishing and so strength-giving that the native of the mountains of the Madeira region would tramp up hill and down all day on a pinch of powdered coca and require no other sustenance. I was fired with a longing to ascend the Amazon. Also with a longing to open up a trade in coca with all the world. During months I dreamed that dream, and tried to contrive ways to get to Para and spring that splendid enterprise upon an unsuspecting planet. But all in vain. A person may PLAN as much as he wants to, but nothing of consequence is likely to come of it until the magician _circumstance _steps in and takes the matter off his hands. At last Circumstance came to my help. It was in this way. Circumstance, to help or hurt another man, made him lose a fifty-dollar bill in the street; and to help or hurt me, made me find it. I advertised the find, and left for the Amazon the same day. This was another turning-point, another link. Could Circumstance have ordered another dweller in that town to go to the Amazon and open up a world-trade in coca on a fifty-dollar basis and been obeyed? No, I was the only one. There were other fools there—shoals and shoals of them—but they were not of my kind. I was the only one of my kind. Circumstance is powerful, but it cannot work alone; it has to have a partner. Its partner is man’s _temperament_—his natural disposition. His temperament is not his invention, it is _born _in him, and he has no authority over it, neither is he responsible for its acts. He cannot change it, nothing can change it, nothing can modify it—except temporarily. But it won’t stay modified. It is permanent, like the color of the man’s eyes and the shape of his ears. Blue eyes are gray in certain unusual lights; but they resume their natural color when that stress is removed.
