Burley's next move was to lift the left front foot of Moore's horse and expose the bottom to view.

Evidently the white mustang did not like these proceedings, but he behaved himself.

The iron shoe on this hoof was somewhat triangular in shape.

When Burley held the larger piece of mud, with its imprint, close to the hoof, it was not possible to believe that this iron shoe had not made the triangular-shaped track.
Burley let go of the hoof and laid the pieces of mud down.

Slowly the other men straightened up.
