The purpose of the present volume differs from that of those which have preceded it in the following respect: It is essentially a book for the use of readers who desire to make as much a success of their vacation as possible, to know how to meet and overcome difficulties in the simplest way. It is even more extended in its purpose, for it exploits a number of schemes for the benefit of those who have permanent camps or dwellings in field and forest; also for those whose sphere of adventure takes them into the untrodden wilderness. The matter, except where it is expressly stated otherwise, is entirely new and original, and, as the author believes, will prove practically very useful to those for whom the book is designed. The diagrams and their explanations have been made whit great care, so as to render them as easily intelligible and as unambiguous. This is an EXACT reproduction of a book published 1906.
