And from that time his history is closely identified with that of his country. To tell you of the leading incidents even of his career would be to give you in a nutshell the history of the United States for that period. His noted contest with Stephen A. Douglas, his election to the presidency, his re-election, his celebrated Emancipation Proclamation, all these matters belong to the story of the stirring events of those years of our history. Then came the sad ending of this noble life; the cruel assassination of the beloved President, and the great man of the time. Boys, you who have studied his character, can you tell me what made Abraham Lincoln great? CHAPTER XV. MORSE, SAMUEL FINLEY BREESE. Long before he reached the pinnacle of his fame, Samuel Finley Breese Morse passed many quiet summer hours on the pleasant wooded borders of the ravine overlooking the peaceful Sconondoah; and even to this day if you wander through the beautiful Sconondoah wood and hunt out its sequestered nooks, you will find here and there, cut deep in the rugged bark of old forest trees, the initials S.F.B.M., carved by his hand more than half a century ago. Professor Morse was born at Charlestown, Mass., in 1791. He was the son of a Congregational clergyman, who was the author of a series of school geographies familiar to our fathers and mothers in their schooldays. He was educated at Yale College, and, intending to become a painter, went to London to study art under Benjamin West; but becoming interested in scientific studies he was for many years president of the National Academy of Design in New York. He resided abroad three or four years. On returning home in 1832 the conversation of some gentlemen on shipboard in regard to an experiment which had recently been tried in Paris with the electro-magnet, interested him and started a train of thought which gave him the conception of the idea of the telegraph. The question arose as to the length of time required for the fluid to pass through a wire one hundred feet long. Upon hearing the answer, that it was instantaneous, the thought suggested itself to Prof. Morse that it might be carried to any distance and be the means of transmitting intelligence. Acting upon the thought, he set to work, and before the ship entered New York harbor had conceived and made drawings of the telegraph. He plodded on through weary years endeavoring to bring his invention to perfection, meeting on every hand jeers and ridicule and undergoing many painful reverses in fortune; but for his indomitable will, he would have given up his project long before he succeeded in bringing it before the public, for all thought it a wild scheme which would amount to nothing.
