Grateful acknowledgment is made to the artist, Mr. Coert Du Bois, who has so faithfully represented these animals.
He never could have drawn them so true to life had he not
met them on tote road and trail. To Mr. George B. Sudworth,
dendrologist of the Forest Service, also I am indebted for his
kind assistance in classifying the animals. My thanks are due
in no small measure to numerous friends among lumbermen
and foresters throughout the country and in Canada for furnishing important scientific “facts” concerning these creatures
their ranges and habits.
