With the growth of a thing so unfavored as was the Underground Road, local conditions must have a great deal to do. The characteristics of small and scattered localities, and even of isolated families, are of the first importance in the consideration of a movement such as this. These little communities were in general the elements out of which the underground system built itself up. The sources of the convictions and confidences that knitted these communities together in defiance of what they considered unjust law can only be learned by the study of local conditions. The incorporation in the Constitution of the compromises concerning slavery doubtless quieted the consciences of many of the early friends of universal liberty. It was only natural, however, that there should be some that would hold such concessions to be sinful, and in violation of the principles asserted in the Declaration of Independence and in the very Preamble of the Constitution itself. These persons would cling tenaciously to their views, and would aid a fugitive slave whenever one would ask protection and help. It is not strange that representatives of this class should be found more frequently among the Quakers than any other sect. In southeastern Pennsylvania and in New Jersey the work of helping slaves to escape was, for the most part, in the hands of Quakers from the beginning. This was true also of Wilmington, Delaware, New Bedford, Massachusetts, and Valley Falls, Rhode Island, as of a number of important centres in western Pennsylvania, and eastern, central and southwestern Ohio, in eastern Indiana, in southern Michigan and in eastern Iowa. Anti-slavery views prevailed against the first attempts at enforcement of the Fugitive Slave Law of 1793 in Massachusetts, and spread to other localities in the New England states. When the tide of emigration to the Western states set in, settlers from New England were given more frequent occasions to put their principles into practice in their new homes than they had known in the seaboard region. The western portions of New York and Pennsylvania, as well as the neighboring section of Ohio, called the Western Reserve, are dotted over with communities where negroes learned the meaning of Yankee hospitality. Like Joshua R. Giddings, the people of these communities claimed to have borrowed their abolition sentiments from the writings of Jefferson, whose "abolition tract," Giddings said, "was called the Declaration of Independence."[65] In northern Illinois there were many centres of the New England type, though, of course, not all the underground stations in that region were kept by New Englanders.
