VIEWS OF TYPICAL TREES, ETC. Having rather unusual oppor- 

 tunity of studying trees in the field, on account of personally gathering 

 the woods used in AMERICAN WOODS, the author is in the habit of making 

 photographs that are of especial interest in the study of trees. 

 The subjects selected are mainly as follows : 



(a ) Isolated individual or small groups of trees, which show characteristic 

 habits of growth, natural environment, etc. Deciduous species are photo- 

 graphed generally both in summer and winter, to show both leafy and leafless 

 condition.* 



(b ) Characteristic barks of trees, a one- foot rule being displayed to show 

 size of trunk. 



(c) Flowers of trees, and such conditions of leaves as exist at the corre- 

 sponding season of the year. 



(d} Fruits and nature leaves. 



(e) Leafless branchlets, showing the interesting characters by which the 

 trees may be known in winter. 



The subjects of classes c, d and e are photographed while fresh, even before 

 their wilting, against a background ruled into square inches, by means of 

 which natural sizes are at once apparent. The pictures of classes b, d and e, as 

 pertains to the trees of the Northern States and Canada appear in our HAND- 

 BOOK OF THE TREES. 



Prices: Contact-print photographs (mostly 5x7 or 5x8 in., excepting of 

 classes b and <?) unmounted, each 20 cents ; mounted, 25 cents. Stereopticon 

 views, 50 cents ; $10 per twenty-five. Enlargements and transparencies quoted 

 on request. 



*In ordering pictures of trees, please state whether leafy or leafless condition of trees is 

 desired, or both.
