DEARBORN Park.—The first, and for many years the only public park in the city, is an oblong piece of ground extending from Randolph to Washington street, and from Michigan avenue to Dearborn place, and contains one and a half acres. The ground was presented to the city by the United States, to be used for ever as a public Park. It is enclosed by a neat iron railing, and planted with trees.
