Working the guns in small revolving turrets, as by Ericsson's or by Coles's plan, and loading and cooling them by steam-power, and taking up their recoil by springs in a short space, as by Stevens's plan, are improvements in this direction.
Notwithstanding the asperities of Ericsson's character in regard to his professional work, and his entire lack of effort to make friends among the learned of his day, recognition and unsought honors came in upon him.
This terrible disaster threw an entirely undeserved stigma upon the ship herself and upon Ericsson's work, and it was not until many years after that his name was entirely free from some kind of reproach in connection with the "Princeton" and the deplorable results of the accident on board.
With the "Destroyer," and his work in connection with her, closes the record of Ericsson's connection with the advance in naval construction. During these later years of his life it must not be supposed that he was less busily occupied than in earlier life. His was a nature which knew no rest, and to the last day of his life he was literally in the harness.
The life of the former was passed in Sweden and does not concern us, but John Ericsson's name is closely connected with the history of the United States. He was the son of a poor miner, and one of his earliest recollections was of the sheriff coming to take away all their household goods in payment of a debt.
In pursuance of this idea they recommended the construction of three vessels, Ericsson's floating battery, a broadside vessel later known as the "Ironsides," and the "Galena." Mr. C.S. Bushnell, who was instrumental in bringing Ericsson's plans actually before the Board, later associated with himself and Ericsson in the project two gentlemen of means, and large manufacturers of iron plate, Mr.
This was the U.S.S. "Princeton," which marks an epoch as the first screw vessel-of-war. She was followed by the French "Pomone" in 1843, and the English "Amphion" in 1844, for the equipment of which Ericsson's agent in England, Count Von Rosen, received commissions from the French and English governments respectively.
Ericsson's contributions to the art of naval warfare are embodied in the "Princeton," the "Monitor" and its class, and the "Destroyer." In the "Princeton" the material used was wood, and in the "Monitor" and "Destroyer" iron, following simply the developments of the age. In the three the means of propulsion was by screw-propeller.
Count Platen looked at the drawing on the boy's lap, and listened intently while the young inventor explained how the machine should work. He was astounded at the knowledge the boy had of engineering. "You're Olof Ericsson's son, aren't you?" he asked finally. The boy nodded. "Yes, I'm John Ericsson; I've an older brother Nils, who's fifteen." "Is Nils as much of an engineer as you are?"
The imprint left by Ericsson's life on the engineering practice of his age was deep and lasting, and if one may dare look into the future, the day is far removed when engineers will have passed beyond their dependence on his life and labors.
