BULLETIN 194: THE TREES OF VERMONT 



By G. p. Burns and C. H. Otis^ 



INTRODUCTION 



The supply of bulletin 7Z, entitled "The Trees of Vermont," has 

 been exhausted for several years. Repeated calls from all parts of the 

 State and especially from the schools make it evident that its revision 

 and reissue would be welcomed. 



The present publication represents a revision of Bulletin 7?i of the 

 Vermont Agricultural Experiment Station, issued in 1899, and of Bul- 

 letin 16, Vol. XIV, N. S., of the University of Michigan, issued in 1913 

 under the authorship of the junior writer". In the preparation of 

 the present bulletin the authors have followed largely the general 

 scheme and arrangement of the Michigan publication. Two chapters, 

 "How to Study the Trees" and "Artificial Keys, How Made and 

 Used," except for a few minor changes, ase from the Michigan bulletin. 

 The artificial keys for identification and the manual of trees have been 

 adapted to the slightly different Vermont conditions. Most of the 

 reproductions published in this bulletin have been made from new- 

 plates photographed from the drawings originally used to illustrate the 

 Michigan bulletin. Credit has been indicated in each case. Finally, 

 there have been added a series of bark photographs by the senior 

 author, while the junior has contributed four original plates of draw- 

 ings and accompanying descriptions and a section dealing with the 

 identification and structure of Vermont woods. Upon the senior 

 author has devolved the final bringing together of the component parts 

 and the necessary editorial work involved. 



This bulletin is intended primarily for the use of pupils in our 

 l)ublic schools and of persons not especially trained in botany. For 

 this reason the use of technical terms has been avoided whenever pos- 

 sible. In several cases such terms were necessary, but with the help 

 of the glossary (page 233) their meaning can be easily understood. 



The order of arrangement and nomenclature are essentially those 

 of Gray's Manual. Following a tendency which is steadily gaining 

 favor, all species names are printed with a small letter, regardless of 

 their origin. 



1 Professor Otis, formerly curator of the botanical garden and arboretum of 

 the University of Michigan, spent several months during the past year at this 

 institution, collaborating with the senior author in the preparation of this bulletin. 



- The authors take this occasion to express their appreciation of the courtesy 

 of the University of Michigan authorities in allowing them to malce such liberal 

 use of the material from the former bulletin in their present work.
