The ornamental design for a dart, substantially as shown and described.
FIG. 1 is a top plan view of the dart showing my new design;
FIG. 2 is a bottom plan view of the dart;
FIG. 3 is a one side elevation view of the dart; and
FIG. 4 is another side elevation view of the dart.
The characteristic feature of my design resides in the particular conically
tapered configuration of the head and tip portion in combination with the
finned body as shown.
