Joseph Clarke, one of the most widely known engineers on the Ontario and Quebec division of the Canadian Pacific died at his home in Elora, Ont., last May. He belonged to a thoroughgoing railroad family. Three of his brothers have engines on the Grand Trunk or the C. P. R. and three of his sons are in railroad employ. Mr. Clarke, who was in his 58th year, came to Toronto from Stockport, Eng., and took service with the Credit Valley Line, which then ran into Toronto. When the C. P. R. took over this line in 1883 Mr. Clarke went into the service of the big corporation and has remained with them ever since. For 27 years he has been on the passenger train between Elora and Cataract Jct. He was known on the road as a first-class mechanic and did all the running repairs on his own engine. For 40 years altogether Mr. Clarke has been engaged in railroad work, and for 35 of that 40 he has had an engine. His son, Roland, is train despatcher at Eau Claire, Wis.; Howard is station agent at Melrose, Man., and Percy is a telegraph operator at Warren, Wis.
