The Trees of Vermont 37 



Thompson's Natural History of Vermont in 1842. A supplement to this 

 was prepared by Professor Joseph Torrey in 1853. Professor Perkins again 

 summarized the available information in his Flora of Vermont in 1887. The 

 forest flora of the Connecticut valley was well discussed by Flint and Jesup 

 in their Trees and Shrubs of New Hampshire, 1891. The information fiu-- 

 nished in the above lists has been freely drawn upon. 



C. G. Pringle very thoroughly explored the forest areas of the Cham- 

 plain valley and of northern Vermont some twenty-five years ago. More 

 recently this work has been continued by several botanists. It is not ex- 

 pedient here to mention the contributions of all, but credit must at least be 

 given to those of President Ezra Brainerd regarding the flora of Addison 

 county, of Dr. A. J. Grout regarding that of Windham county and of W. W. 

 Eggleston regarding that of Rutland county. Mr. Eggleston has in addi- 

 tion made several trips through Bennington county and has also explored 

 parts of the extensive forest areas of Essex county, thus adding much to the 

 accuracy of the information regarding each of these regions. As a result it 

 is believed that the general facts concerning the distribution of the trees of 

 the state are fairly well understood and the attempt has been made to sum- 

 marize these in the present list. There is still opportunity, however, for 

 the botanical exploration of the forests, especially in the southern and the 

 northeastern portions of the state and it is hoped that such imperfections 

 as exist in this publication may be a stimulus in this direction. 



The preparation of the drawings' and of the original manuscript was 

 made by Miss Clark in connection with the botanical studies of her senior 

 year at the University of Vermont (1897-8). The publication was delayed 

 a year and a half and the rapid increase in knowledge of the state flora 

 during this period made some revision necessary. Mr. Clifton D. Howe 

 had immediate charge of this revision and of the final preparation of the 

 matter for the press. Mr. W. W. Eggleston contributed much to the value 

 of the publication by carefully revising and editing the statements concern- 

 ing the occurrence and distribution of the species, especially as regards the 

 Connecticut valley and southwestern Vermont. Professor F. A. Waugh 

 furnished the statements about the cultivated plums and cherries and aided 

 in other ways. 



Thanks are due President Ezra Brainerd, Professor F. A. Balch, Rev. 

 J. A. Bates, and other members of the Vermont botanical club who have 

 kindly offered suggestions and read proofs.
