Adams thought that, as no one seemed to care what he did, he would try to cultivate this tenth mind, though necessarily at the expense of the other nine. He frankly acted on the rule that a teacher, who knew nothing of his subject, should not pretend to teach his scholars what he did not know, but should join them in trying to find the best way of learning it. The rather pretentious name of historical method was sometimes given to this process of instruction, but the name smacked of German pedagogy, and a young professor who respected neither history nor method, and whose sole object of interest was his students' minds, fell into trouble enough without adding to it a German parentage. The task was doomed to failure for a reason which he could not control. Nothing is easier than to teach historical method, but, when learned, it has little use. History is a tangled skein that one may take up at any point, and break when one has unravelled enough; but complexity precedes evolution. The Pteraspis grins horribly from the closed entrance. One may not begin at the beginning, and one has but the loosest relative truths to follow up. Adams found himself obliged to force his material into some shape to which a method could be applied. He could think only of law as subject; the Law School as end; and he took, as victims of his experiment, half-a-dozen highly intelligent young men who seemed willing to work. The course began with the beginning, as far as the books showed a beginning in primitive man, and came down through the Salic Franks to the Norman English. Since no textbooks existed, the professor refused to profess, knowing no more than his students, and the students read what they pleased and compared their results. As pedagogy, nothing could be more triumphant. The boys worked like rabbits, and dug holes all over the field of archaic society; no difficulty stopped them; unknown languages yielded before their attack, and customary law became familiar as the police court; undoubtedly they learned, after a fashion, to chase an idea, like a hare, through as dense a thicket of obscure facts as they were likely to meet at the bar; but their teacher knew from his own experience that his wonderful method led nowhere, and they would have to exert themselves to get rid of it in the Law School even more than they exerted themselves to acquire it in the college. Their science had no system, and could have none, since its subject was merely antiquarian. Try as hard as he might, the professor could not make it actual.
