Squares and Parks.

The oldest and best finished public square is Portsmouth Square, commonly called the Plaza, on the west side of Kearny street, extending from Clay street to Washington street, and directly fronting the old City Hall. Besides these are Washington, Union, Columbia, Lobos, Alcatraz, Lafayette, Jefferson, Alta, Hamilton and Alamo Squares, with Yerba Buena, Buena Vista and Golden Gate Parks. The last named covers nearly 1,200 acres, (of sand at present.) Of these, the Plaza and Washington Square are the principal ones which have been sufficiently improved to merit even passing notice. To these one may add South Park, a small but elegant private inclosure occupying the centre of the block between Bryant and Brannan streets.
