The Smithsonian Institution has been a blessing in many ways. It organized a system of telegraphic meteorology, and gave to the world "that most beneficent national application of modern sciences,--the storm warnings." In the year 1891 the Institution received valuable aid from Mr. Thomas G. Hodgkins of Setauket, N.Y., by the gift of $200,000. The income from $100,000 is to be used in prizes for essays relating to atmospheric air. Mr. Hodgkins, also an Englishman, died Nov. 25, 1892, nearly ninety years old. He gave $100,000 to the Royal Institution of Great Britain, and $50,000 each to the Society for Prevention of Cruelty to Children, and to Animals. He made his fortune, and having no family, spent it for "the diffusion of knowledge among men." A very interesting feature was added to the work of the Smithsonian Institution in 1890, when Congress appropriated $200,000 for the purchase of land for the National Zoölogical Park. As no native wild animals in America seem safe from the cupidity of the trader, or the slaughter of the pleasure-loving sportsman, it became necessary to take measures for their preservation. About 170 acres were purchased on Rock Creek, near Washington; and there are already more than 500 animals--bisons, etc.--in these picturesque grounds. These will be valuable object-lessons to the people, and help still further to carry out James Smithson's idea, "the increase and diffusion of knowledge among men." PRATT, LENOX, MARY MACRAE STUART, NEWBERRY, CRERAR, ASTOR, REYNOLDS, AND THEIR LIBRARIES. ENOCH PRATT. Enoch Pratt was born in North Middleborough, Mass., Sept. 10, 1808. He graduated at Bridgewater Academy when he was fifteen; and a position was found for him in a leading house in Boston, where he remained until he was twenty-one years of age. He had written to a friend in Boston two weeks before his school closed, "I do not want to stay at home long after it is out." The eager, ambitious boy, with good habits, constant application to business, the strictest honesty, and good common-sense, soon made himself respected by his employers and his acquaintances. He removed to Baltimore in 1831, when he was twenty-three years old, without a dollar at his command, and established himself as a commission merchant. He founded the wholesale iron house of Pratt & Keith, and subsequently that of Enoch Pratt & Brother. "Prosperity soon followed," says the Hon. George Wm. Brown, "not rapidly but steadily, because it was based on those qualities of honesty, industry, sagacity, and energy, which, mingled with thrift, although they cannot be said to insure success, are certainly most likely to achieve it." Six years after coming to Baltimore, when he was twenty-nine years old, Mr. Pratt married Maria Louisa Hyde, Aug. 1, 1837. Her paternal ancestors were among the earliest settlers of Massachusetts; her maternal, a German family who settled in Baltimore over a century and a half ago.
