This report also places the accident on the road from Tarcutta: Adams' hotel must have been on that road:
"FATAL MAIL ACCIDENT.-On Friday afternoon, at about two o'clook, a Mr. Carr, the mail driver, was returning from Tarcutta, on the gap between Mr. Stachan's and Mr. Adams', the horses became frightened, and the driver of the coach lost all control over them. The coach came down the hill at a fearful pace, over logs, stumps, and all obstacles which presented themselves. The coach was brought to a standstill in a deep creek at the bottom of the hill, where the vehicle came in contact with the limb of a tree. The shock overturned the coach and smashed it to pieces. The driver sustained injuries of such a nature that he died shortly afterwards. Some diggers who were passing by, conveyed the unfortunate mailman under the shade of a tree, where everything was done that could be thought of, to restore animation. Deceased, when picked up, was black in the face ; the blood running very fast from his left ear. As soon as possible he was removed in a spring cart to Adams' hotel, but he continued insensible until ten o'clook, when he died. The only outward mark of injury was a slight scratch on the right temple. Deceased was burled on Sunday.-
