The area described is bounded on the west by Bowman's Ditch, on the north by what was then marsh land (Eagle Ave.?), and on the south by the Bay of San Francisco. The eastern boundary abuts the Augenbaugh Tract, but no street names or landmarks are shown to help make a definitive judgment. Central, Jefferson, and Washington Aves. pass through the property in an east-west direction. The perimiter of the parcel is outlined in pale green, while smaller areas of land inside are outlined in pale red. The streets are tinted pale yellow. The Chipman West Tract is not included in the "Tract List" compiled by Quentin. The notes are on official Alameda County Surveyor's Office stationery.
