I claim the ornamental design for a cane, as shown and described.
FIG. 1 is a perspective view of a cane, showing my new design;
FIG. 2 is a front elevational view thereof;
FIG. 3 is a right-side elevational view thereof;
FIG. 4 is a left-side elevational view thereof;
FIG. 5 is a top plan view thereof;
FIG. 6 is a bottom plan view thereof;
FIG. 7 is a perspective view of an alternate use thereof;
FIG. 8 is a perspective view of another alternate use thereof; and,
FIG. 9 is a partial, enlarged front elevational view thereof, taken along line 9-9 of FIG. 2.
The broken lines showing a U-shaped cane head in FIGS. 1-6 and an alternate cane head in FIG. 7 and another alternate cane head in FIG. 8 and the interior details of the circular elements shown on the shaft of the cane in FIGS. 1-8 depict environmental matter while the design is in-use, and form no part of the claimed design.
