As years went by, and the unobtrusive, energetic man came to middle life, he was sought to fill various positions of honor and trust in Baltimore. He was made director and president of a bank, which position he has held for over twoscore years, director and vice-president of railroads and steamboat lines, president of the House of Reformation at Cheltenham (for colored children), and of the Maryland School for the Deaf and Dumb at Frederick. He has also taken active interest in the Maryland Institute for the Promotion of the Mechanic Arts, and is treasurer of the Peabody Institute. For years he has been one of the finance commissioners elected by the city council, without regard to his political belief, but on account of his ability as a financier, and his wisdom. He is an active member of the Unitarian Church. For several years Mr. Pratt had thought about giving a free public library to the people of Baltimore. In 1882, when he was seventy-four, Mr. Pratt gave to the city $1,058,000 for the establishing of his library, the building to cost about $225,000, and the remainder, a little over $833,000, to be invested by the city, which obligated itself to pay $50,000 yearly forever for the maintenance of the free library. Mr. Pratt also provided for four branch libraries, which cost $50,000, located wisely in different parts of the city. The main library was opened Jan. 4, 1886, with appropriate ceremonies. The Romanesque building of Baltimore County white marble is 82 feet frontage, with a depth of 140 feet. A tower 98 feet high rises in the centre of the front. The floor of the vestibule is in black and white marble, and the wainscoting of Tennessee and Vermont marbles, principally of a dove color. The reading-room in the second story is 75 feet long, 37 feet wide, and 25 feet high. The walls are frescoed in buff and pale green tints, the wainscoting is of marble, and the floor is inlaid with cherry, pine, and oak. The main building will hold 250,000 volumes. The Romanesque branch libraries are 40 by 70 feet, one story in height, built of pressed brick laid with red mortar, with buff stone trimmings. The large reading-room in each is light and cheerful, and the book-room has shelving for 15,000 volumes. The librarian's report shows that in nine years, ending with Jan. 1, 1895, over 4,000,000 books have been circulated among the people of Baltimore. Over a half-million books are circulated each year. The library possesses about 150,000 volumes. "The usefulness of the branch libraries cannot be stated in too strong terms," says the librarian, Mr. Bernard C. Steiner. Fifty-seven persons are employed in the library,--fourteen men and forty-three women.
