I claim the ornamental design for a portion of a ladder, as shown and described.

FIG. 1 is a perspective view of a portion of a ladder, showing my new design;

FIG. 2 is a cross-sectional view thereof, taken generally along lines 2--2 of FIG. 1;

FIG. 3 is a cross-sectional view thereof, taken generally along lines 3--3 of FIG. 1;

FIG. 4 is a front elevational view thereof, the rear elevational view being a mirror image thereof; and,

FIG. 5 is a left-side elevational view thereof, the right-side elevational view being a mirror image thereof.

The broken lines showing a remaining portion of a ladder in FIG. 1 depict environmental matter and form no part of the claimed design.

Falkenstrom, Erik L.
