(preface 



ver's Engineering" appeared in the Saturday 

 Evening Post, and I am indebted to McClures 

 for permission to use " Beaver Pioneers." 



Beaver works are of economical and educa- 

 tional value besides adding a charm to the wilds. 

 The beaver is a persistent practicer of conserva- 

 tion and should not perish from the hills and 

 mountains of our land. Altogether the beaver has 

 so many interesting ways, is so useful, skillful, 

 practical, and picturesque that his life and his 

 deeds deserve a larger place in literature and in 

 our hearts.
