I was a reasonably good student in college, standing just within the first tenth of my class, if I remember rightly; although I am not sure whether this means the tenth of the whole number that entered or of those that graduated. I was given a Phi Beta Kappa “key.” My chief interests were scientific. When I entered college, I was devoted to out-of-doors natural history, and my ambition was to be a scientific man of the Audubon, or Wilson, or Baird, or Coues type—a man like Hart Merriam, or Frank Chapman, or Hornaday, today. My father had from the earliest days instilled into me the knowledge that I was to work and to make my own way in the world, and I had always supposed that this meant that I must enter business. But in my freshman year (he died when I was a sophomore) he told me that if I wished to become a scientific man I could do so. He explained that I must be sure that I really intensely desired to do scientific work, because if I went into it I must make it a serious career; that he had made enough money to enable me to take up such a career and do non-remunerative work of value if I intended to do the very best work there was in me; but that I must not dream of taking it up as a dilettante. He also gave me a piece of advice that I have always remembered, namely, that, if I was not going to earn money, I must even things up by not spending it. As he expressed it, I had to keep the fraction constant, and if I was not able to increase the numerator, then I must reduce the denominator. In other words, if I went into a scientific career, I must definitely abandon all thought of the enjoyment that could accompany a moneymaking career, and must find my pleasures elsewhere.
After this conversation I fully intended to make science my lifework. I did not, for the simple reason that at that time Harvard, and I suppose our other colleges, utterly ignored the possibilities of the faunal naturalist, the outdoor naturalist and observer of nature. They treated biology as purely a science of the laboratory and the microscope, a science whose adherents were to spend their time in the study of minute forms of marine life, or else in section-cutting and the study of the tissues of the higher organisms under the microscope. This attitude was, no doubt, in part due to the fact that in most colleges then there was a not always intelligent copying of what was done in the great German universities. The sound revolt against superficiality of study had been carried to an extreme; thoroughness in minutiae as the only end of study had been erected into a fetish. There was a total failure to understand the great variety of kinds of work that could be done by naturalists, including what could be done by outdoor naturalists—the kind of work which Hart Merriam and his assistants in the Biological Survey have carried to such a high degree of perfection as regards North American mammals. In the entirely proper desire to be thorough and to avoid slipshod methods, the tendency was to treat as not serious, as unscientific, any kind of work that was not carried on with laborious minuteness in the laboratory. My taste was specialized in a totally different direction, and I had no more desire or ability to be a microscopist and section-cutter than to be a mathematician. Accordingly I abandoned all thought of becoming a scientist. Doubtless this meant that I really did not have the intense devotion to science which I thought I had; for, if I had possessed such devotion, I would have carved out a career for myself somehow without regard to discouragements.
As regards political economy, I was of course while in college taught the laissez-faire doctrines—one of them being free trade—then accepted as canonical. Most American boys of my age were taught both by their surroundings and by their studies certain principles which were very valuable from the standpoint of National interest, and certain others which were very much the reverse. The political economists were not especially to blame for this; it was the general attitude
