X PREFACE. 



of Mathematics at this College, for his kind assistance in 

 looking over the proof sheets of Parts I. and II. of this 

 volume. 



Herr Forstassessor Alwin Schenck has been good enough 

 to obtain for me the working plan for the Krumbach Communal 

 Forest, contained in Appendix A, and I herewith tender to 

 him my best thanks. 



The extract from the working plan for the Herrenwies 

 Range, Appendix C, was prepared by me while I was on 

 tour with the students of this College during the summer 

 of 1893, the records having been kindly placed at niy disposal 

 by Herr Oberforster Ziegler of Herrenwies.
