Howard Chapelle gathered up Adney's notes and organized them into a book on kayaks. He then appended two chapters on skin boats to make this the definitive book on portable native watercraft. I say portable because the book does not deal with dugouts which ranged from Florida all the way up to Alaska.
Since this book was published, a lot more books about kayaks have come out and so this is no longer the definitive work on kayaks that it once was, but it definitely belongs in every kayak builder's library.
And then there is of course all the material on bark canoes which comprises the bulk of this book. As far as I know, Adney's research on canoes is still the definitive word on the subject.
Kayaks and canoes documented in this book are no longer being built and specimens in museums are poorly preserved so that in the end further contributions to the topic are likely to be marginal. So we thank the people who compiled the data.
