A few months before his death I gave my father a copy of the Collected Poems of Robert Service, a British-Canadian poet whose long ballads he had discovered in his younger, single days while working on building sites in Alaska and Canada. He spoke often of his favourite, ‘The Cremation of Sam McGee’, about a gold miner in the Yukon who honours his dying fellow prospector’s request for cremation rather than interment in a frozen grave. Hauling Sam McGee’s body for days on a dog sled, the narrator eventually finds a wrecked boat along a lake shore and uses it as a makeshift crematorium.
