There is a tendency to apply the term "miraculous" to the career of every hero, and in a sense such description is, of course, true. The life of every man, however restricted its range, is something of a miracle; but the course of a single life, like that of humanity, is assuredly based on a development that proceeds from a series of causations. Holmes says that the education of a man begins two centuries before his birth. We may recall in this connection that Lincoln came of good stock. It is true that his parents belonged to the class of poor whites; but the Lincoln family can be traced from an eastern county of England (we might hope for the purpose of genealogical harmony that the county was Lincolnshire) to Hingham in Massachusetts, and by way of Pennsylvania and Virginia to Kentucky. The grandfather of our Abraham was killed, while working in his field on the Kentucky farm, by predatory Indians shooting from the cover of the dense forest. Abraham's father, Thomas, at that time a boy, was working in the field where his father was murdered. Such an incident in Kentucky simply repeated what had been going on just a century before in Massachusetts, at Deerfield and at dozens of other settlements on the edge of the great forest which was the home of the Indians. During the hundred years, the frontier of the white man's domain had been moved a thousand miles to the south-west and, as ever, there was still friction at the point of contact. The record of the boyhood of our Lincoln has been told in dozens of forms and in hundreds of monographs. We know of the simplicity, of the penury, of the family life in the little one-roomed log hut that formed the home for the first ten years of Abraham's life. We know of his little group of books collected with toil and self-sacrifice. The series, after some years of strenuous labour, comprised the Bible, _Aesop's Fables_, a tattered copy of Euclid's _Geometry_, and Weems's _Life of Washington_. The _Euclid_ he had secured as a great prize from the son of a neighbouring farmer. Abraham had asked the boy the meaning of the word "demonstrate." His friend said that he did not himself know, but that he knew the word was in a book which he had at school, and he hunted up the _Euclid_. After some bargaining, the _Euclid_ came into Abraham's possession. In accordance with his practice, the whole contents were learned by heart. Abraham's later opponents at the Bar or in political discussion came to realise that he understood the meaning of the word "demonstrate." In fact, references to specific problems of Euclid occurred in some of his earlier speeches at the Bar.
