uralist collects many bugs and reptiles and butterflies and studies their ways a long time patiently. By this means he is presently able to group these creatures into families and subdivisions of families by nice shadings of differences observable in their characters. Then he labels all those shaded bugs and things with nicely descriptive group names, and is now happy, for his great work is completed, and as a result he intimately knows every bug and shade of a bug there, inside and out. It may be true, but a person who was not a naturalist would feel safer about it if he had the opinion of the bug. I think it is a pleasant System, but subject to error.
The Observer of Peoples has to be a Classifier, a Grouper, a Deducer, a Generalizer, a Psychologizer; and, first and last, a Thinker. He has to be all these, and when he is at home, observing his own folk, he is often able to prove competency. But history has shown that when he is abroad observing unfamiliar peoples the chances are heavily against him.
