Excerpt: "The history of America is the story of trail-makers, pioneers in every sense of the word. Our forefathers had trails to make in new fields of government, of invention and in city building, but before all, smoothing the way for all, came the men and women who explored and ploughed and planted the wilderness. Their story will grow in interest as the years pass. Their deeds have already taken on something of the dim quality of heroic myths. They form the most distinctive of our contributions to history and poetry."
