are passed, by maps and by descriptions in the text 

 which point out enough of the salient features of each 

 tree or shrub to make the identification sure. Of 

 course, in using this book, it must be borne in mind 

 that it would be utterly impossible to locate on the 

 maps every tree and shrub passed along the walks. 

 This would result only in a mass of black spots from 

 which it would be impossible to distinguish anything. 

 It was therefore thought best to locate some of the 

 representative types clearly and distinctly rather than 

 to attempt to locate all from which none could be 

 definitely found. Try to find shrubs or trees on the 

 maps at easily distinguishable points and work from 

 these to others, verifying, as you go along, by the 

 descriptive text. If you find you have not judged 

 the distance rightly, the descriptive text should act as 

 a guide to set you right. 



The best results, in the use of this handbook, will 

 be obtained if the rambler will follow up the identifi- 

 cation effected by it, with a more extended study of 

 each tree or shrub, pursuing the details of leaf, 

 flower, bark and bud in botanical text books or 

 larger works of reference, such as cyclopedias on 

 horticulture. 



For these more extended studies, I strongly recom- 

 mend Gray's "Field, Forest, and Garden Botany," 

 revised by Prof. L. H. Bailey; Keeler's "Our Native 

 Trees" and "Our Northern Shrubs"; Apgar's "Trees 

 of the Northern United States"; Dame and Brooks's 

 "Handbook of the Trees of New England." Any of
