INTRODUCTION 



VII 



The bibliography of Swiss Forestry has been chiefly compiled by P. Bertholet of Lausanne ; and 

 work on the Bibliography has been done in London also by L. W. Burridge and E. J. Wayland. 



The greater part of the titles enumerated, however, have been seen by the compiler. The titles 

 not copied in libraries under his special supervision and those excerpted from other bibliographies 

 are marked by a dagger (f) at the end of the entry. Titles copied from other bibliographies are 

 often incomplete, and the Arboretum will be grateful for any information which will make it possible 

 to complete incomplete entries, and also for references to titles not included in this Bibliography. 

 These will find a place in supplements of this Bibliography which may be published from time to 

 time.
