Hume had been trailing Black Bart almost from the beginning of the thief’s career. He visited the sites of all the robberies and patiently put together a valuable list of information. Witnesses in settlements near the scenes of the robberies described seeing a polite, friendly man in his fifties, about five foot eight or ten in height with brownish gray hair, a fierce gray mustache and matching goatee, carrying a bedroll (which Hume correctly inferred carried his duster, sack disguise, shotgun and loot), passing through on foot and quickly disappearing. Hume made special note of the reports by several witnesses that the man’s boots were neatly slit at the toes as if to relieve corns – small wonder, given the territory Bart covered on foot (he never traveled by horse). Hume was well aware that this figure the locals had reported was likely to be the culprit.
