It is of course impossible to understand the life of a politician in another country without study of its conditions and its past. In the case of America this study is especially necessary, not only because the many points of comparison between that country and our own are apt to conceal profound differences of customs and institutions, but because the broader difference between a new country and an old is in many respects more important than we conceive. But in the case of Lincoln there is peculiar reason for carrying such a study far back. He himself appealed unceasingly to a tradition of the past. In tracing the causes which up to his time had tended to conjoin the United States more closely and the cause which more recently had begun to threaten them with disruption, we shall be examining the elements of the problem with which it was his work in life to deal. The "Thirteen United States of America" which in 1776 declared their independence of Great Britain were so many distinct Colonies distributed unevenly along 1,300 miles of the Atlantic coast. These thirteen Colonies can easily be identified on the map when it is explained that Maine in the extreme north was then an unsettled forest tract claimed by the Colony of Massachusetts, that Florida in the extreme south belonged to Spain, and that Vermont, which soon after asserted its separate existence, was a part of the State of New York. Almost every one of these Colonies had its marked peculiarities and its points of antagonism as against its nearest neighbours; but they fell into three groups. We may broadly contrast the five southernmost, which included those which were the richest and of which in many ways the leading State was Virginia, with the four (or later six) northernmost States known collectively as New England. Both groups had at first been colonised by the same class, the smaller landed gentry of England with a sprinkling of well-to-do traders, though the South received later a larger number of poor and shiftless immigrants than the North, and the North attracted a larger number of artisans. The physical conditions of the South led to the growth of large farms, or "plantations" as they were called, and of a class of large proprietors; negro slaves thrived there and were useful in the cultivation of tobacco, indigo, rice, and later of cotton. The North continued to be a country of small farms, but its people turned also to fishery and to commerce, and the sea carrying trade became early its predominant interest, yielding place later on to manufacturing industries. The South was attached in the main, though by no means altogether, to the Church of England; New England owed its origin to successive immigrations of Puritans often belonging to the Congregational or Independent body; with the honourable exception of Rhode Island these communities showed none of the liberal and tolerant Spirit which the Independents of the old country often developed; they manifested,
