Above the estate, in diagonal form, and at one point crossing Fifth Avenue to the west, was the large farm of Henry Brevoort.

More limited holdings, in the names of Gideon Tucker, William Hamilton, and John Morse, separate, in the map, the Brevoort property from the estates of John Mann, Jr., and Mary Mann.

The latter must have been a landowner of some importance in her day, for the fragment of a chart runs into the margin above the line of Thirteenth Street without indicating the beginning of any other ownership.
On the land to the west of the Avenue line may be read "Heirs of John Rogers," "William W.Gilbert," "Nicholson" (the Christian name lies somewhere beyond the map horizon), and "Heirs of Henry Spingler." Irrigation is indicated by a line, running in a general northwesterly direction, bearing the name "Manetta Water," while a thinner line, joining the first line from the northeast, is described as "East Branch of Manetta Water." Manetta Water was the English name.

The Dutch had called it "Bestavaer's Rivulet." It was a sparkling stream, beloved of trout fishermen, rising in the high ground above Twenty-first Street, flowing southeasterly to Fifth Avenue at Ninth Street, then on to midway between the present Eighth Street and Waverly Place, where it swung southwesterly and emptied into the Hudson River near Charlton Street.

It ran between sandhills, sometimes rising to the height of a hundred feet, and marked the course of a famous Indian hunting ground.
The joy of the Izaak Waltons of the past is occasionally the despair of the Fifth Avenue householders of the present.
