Ericsson is now zealously at work in constructing six new iron gun-boats on the plan of the Monitor. If that remarkable structure can be surpassed, he is the man to accomplish it. His ambition is to render the United States impregnable against the navies of the world. "Give me only the requisite means," he writes, "and in a very short time we can say to those powers now bent on destroying republican institutions, '_Leave the Gulf with your frail craft, or perish_!' I have all my life asserted that mechanical science will put an end to the power of England over the seas. The ocean is Nature's highway between the nations. It should be free; and surely Nature's laws, when properly applied, will make it so." His reputation as an engineer is worldwide. In 1852 he was made a Knight of the Order of Vasa by King Oscar of Sweden. The following extract from a poem "To John Ericsson" we translate from "Svenska Tidningen," the Government journal of Stockholm. It is eloquently expressive of the pride and admiration with which he is regarded in his native country. "World-wide his fame, so gracefully adorning His native Sweden with enduring radiance! Not a king's crown could give renown so noble: For his is Thought's great triumph, and the sceptre He wields is over elements his subjects!" Although now in his sixtieth year, Ericsson has the appearance of a man of forty. He is in the very maturity of a vigorous manhood, and retains all the fire and enthusiasm of youth. He has a frame of iron, cast in a large and symmetrical mould. His head and face are indicative of intellectual power and a strong will. His presence impresses one, at the first glance, as that of an extraordinary man. His bearing is dignified and courteous, with a touch perhaps of military _brusquerie_ in his mode of address. He has a keen sense of humor, a kindly and generous disposition, and a genial and companionable nature. He is a "good hater" and a firm friend. Like all men of strong character and outspoken opinions, he has some enemies; but his chosen friends he "grapples to his heart with hooks of steel." He is not a mere mechanician, but has great knowledge of men and of affairs, and an ample fund of information on all subjects. His conversation is engaging and instructive; and when he seeks to enlist coöperation in his mechanical enterprises, few men can withstand the force of his arguments and the power of his personal magnetism. Although his earnings have sometimes been large, his heavy expenditures in costly experiments have prevented him from acquiring wealth. Money is with him simply a means of working out new ideas for the benefit of mankind; and in this way he does not scruple to spend to the utmost limit of his resources. He lives freely and generously, but is strictly temperate and systematic in all his habits.
