Their load exploded at 9:45am on September 4, 1885 on the 6th Line (road) at Douro, Ontario, noted as being a corduroy road and rough to travel in poor weather. Both men were killed in the blast and the only parts of the men that were found were "a finger, two tiny sections of a skull, a tiny piece of cheek identified by the whiskers, and what appeared to be a man's shoulder that was found hanging on the branch of a tree  distant." The blast blew the metal shoes off the horses hooves and broke windows in Selwyn, Ontario and Campbellford. The shock wave was felt in Tweed,  away.
