310 NEW ENGLAND TREES IN WINTER. 



Conn. Geol. and Nat. Hist. Survey,, 1910. The characters under 

 the heading "Wood" were taken chiefly from Sargent's Manual. 

 To obtain information in regard to the dimensions, the distribution 

 and the wood characters of cultivated species, .Bailey's Cyclopaedia 

 of Horticulture and various European works have been freely 

 consulted. 



GENERAL WORKS ON TREES. 



Sargent, C. S. Manual of the trees of North America, 826 pp. 

 Houghton Mifflin Co., Boston, 1905. The best general book 

 on the subject. The text and illustrative drawings are taken 

 chiefly from summer characters, but winter characters receive some 

 attention. 



Sargent, C. S. Silva of North America in 14 quarto volumes. 

 Houghton Mifflin Co., Boston, 1902. The most extensive work 

 of its kind. Except for the more elaborate drawings, of less 

 general value than the Manual, the text of which is practically the 

 same but more conveniently arranged. 



Britton, N. L. North American Trees, 894 pp. Henry Holt 

 & Co., New York, 1908. Of the same general scope as Sargent's 

 Manual. Contains occasional habit photographs. 



Hough, E. B. Handbook of the trees of the northern states 

 and Canada, 470 pp. Lowville, N. Y., 1907. A most valuable 

 publication, without habit illustrations, but with excellent photo- 

 graphs of leaves, fruit and bark and less successful photographs 

 of winter twigs. The keys and the text are based upon 

 summer characters. This is our only book giving bark photographs 

 for each species treated. 



Dame, L.L. & Brooks, H. Handbook of the Trees of New Eng- 

 land, 196 pp. Ginn & Co., Boston, 1901. The best manual for the 

 region covered. 



Emerson, G. B. Eeport on the trees and shrubs of Massachu- 

 setts, 624 pp. in two volumes. Little, Brown & Co., Boston, 1875. 

 Especially valuable for its habit descriptions. 



Collins, J. P. and Preston, H. W. Key to New England 

 Trees, 42 pp. Preston & Bounds Co., Providence, 1909. A useful 

 little book. Contains keys only, based on summer characters. 

 Includes cultivated forms. 



Eogers, Julia E. The Tree Book, 589 pp. Doubleday, Page & 

 Co., New York, 1908. The best of the popular books on trees.
