Byrd..there are three old books,written in 1905?-06?,about this.Wallace wrote the "lure of the labrador wild" to recount his version of what went on.Hubbard's wife,Mina, wrote "a womens way through unknown labrador" to prove that the trip could have been done and Wallace wrote his account of the bigger expedition he put together to explore the area "the long labrador trail"..the best thing to do is read the modern account in the form of a novel by Davidson and Rugge,"great heart".both those guys did a lot of canoeing and wrote "how to" books on the subject.the older books have some of that old style writing that is harder to read and Mina and Wallace had "issues" about the first trip and much is not said by either of them on touchy subjects.George Ellson the guide is Great Heart,read and find out why.and it's just not the adventures on the trail but the change that comes over people having survived something like what they went through.
