"Said one of these men, long past seventy years of age: 'I could carry, paddle, walk and sing with any man I ever saw. I have been twenty-four years a canoe man, and forty-one years in service; no portage was ever too long for me. Fifty songs could I sing. I have saved the lives of ten voyageurs. Have had twelve wives and six running dogs. I spent all my money in pleasure. Were I young again, I should spend my life the same way over. There is no life so happy as a voyageur's life!'"
