Not only did repetition serve to deepen the general recollections of the average operator, but the strange and romantic character of his unlawful business helped to fix them in his mind. Some special occurrences he is apt to remember with vividness, because they were in some way extraordinary. If it be argued that the surviving abolitionists are now old persons, it should not be forgotten that it is a fact of common observation that old persons ordinarily remember the occurrences of their youth and prime better than events of recent date. The abolitionists, as a class, were people whose remembrances of the ante-bellum days were deepened by the clear definition of their governing principles, the abiding sense of their religious convictions, and the extraordinary conditions, legal and social, under which their acts were performed. The risks these persons ran, the few and scattered friends they had, the concentration of their interests into small compass, because of the disdain of the communities where they lived, have secured to us a source of knowledge, the value of which cannot be lightly questioned. If there be doubt on this point, it must give way before the manner in which statements gathered from different localities during the last five years articulate together, the testimony of different and sometimes widely separated witnesses combining to support one another.[24] [24] The value of reminiscences and memoirs is considered in an article on "Recollections as a Source of History," by the Hon.

Morse Stephens in his article entitled "Recent Memoirs of the French Directory," _American Historical Review_, April, 1896, pp. 475, 476, 489, should be read as a corrective by the student that finds himself constrained to have recourse to recollections for information. The elucidation by new light of some obscure matter already reported, the verification by a fresh witness of some fact already discovered, gives at once the rule and test of an investigation such as this. Out of many illustrations that might be given, the following are offered. Mr. J. M. Forsyth, of Northwood, Logan County, Ohio, writes under date September 22, 1894: "In Northwood there is a denomination known as Covenanters; among them the runaways were safe. Isaac Patterson has a cave on his place where the fugitives were secreted and fed two or three weeks at a time until the hunt for them was over. Then friends, as hunters, in covered wagons would take them to Sandusky. The highest number taken at one time was seven. The conductors were mostly students from Northwood. All I did was to help get up the team...."
