[5] Contemporary atlases indicate the "Base Ball Grounds" was about two short blocks west of Spring Grove Avenue, bounded on the south by Alabama Avenue, on the west by Mill Creek, on the north by the imaginary line extending from Monmouth Street, and on the immediate east by the Marietta and Cincinnati Railroad tracks.

It was a block north of the stockyards, and was straight west of the Cincinnati Work House, which was on the northeast corner of Alabama and Colerain, and which served as the jail.

[1] The Cincinnati Enquirer for July 13, 1875, page 4, reported on the planned new ballpark: "Eight acres (the old Union Grounds contained about four) have been leased north of the Stock Yards and west of the Marietta Railroad, which road will build a station at this point and carry passengers the round trip for 15 cents.

The Enquirer's final mention of the ballpark, by then routinely being called the "old" Avenue Grounds, came on September 4, 1896, p.10, announcing an upcoming amateur ball game.

Recently the property near the Avenue Grounds site had been occupied by Hilshire Farms and Kahn's, at 3241 Spring Grove.
