Mr. Lincoln commenced his address in low tones, but his voice became louder and his manner more confident as he proceeded. His speech was an elaborate argument to prove that the original framers of the American Government intended that the Federal Government should exercise absolute control of the Federal territories, so far as the subject of slavery was concerned, and had never surrendered this high privilege to local legislation. This he established by incontrovertible proof, and in so doing quite upset Senator Douglas’ theory of Squatter Sovereignty. Incidentally he vindicated the right of the Republican party to exist. I have not room to quote from this remarkable speech. I am afraid I have already introduced more extracts from speeches than my young readers will enjoy. They are necessary, however, if we would understand what were the views of Mr. Lincoln, and what made him President. The next day Mr. Lincoln’s speech was printed in full in two prominent papers--the _Tribune_ and the _Evening Post_, accompanied by comments of the most favorable character. The first was edited by Horace Greeley, the latter by the poet Bryant, who was nearly as conspicuous a politician as a poet. “No man ever before made such an impression on his first appeal to a New York audience,” said the _Tribune_. Robert Lincoln, Mr. Lincoln’s oldest son, was a student at Harvard, and his father travelled into New England to visit him.
