PARK AND CEMETERY. 
INSECT PESTS AND HOW TO FIGHT THEM 
J. J. Levison, secretary of the American 
Association of Park Superintendents and 
forester in the Department of Parks, 
Brooklyn, N. Y., is the author of one of 
the most interesting and useful handbooks 
on trees that has yet been published 
“Studies of Trees” is a manual and prac- 
tical guide for all interested in the care of 
trees and is published in form to be a suit- 
able field book. It is arranged in sixteen 
small pamphlets, each devoted to a partic- 
ular study and freely illustrated with half- 
tones from photographs taken especially 
for this study or selected from the files of 
the United States Forest Service, in which 
the writer has also been engaged. 
“Studies of Trees” furnishes authorita- 
tive yet popular information on subjects 
relating to trees. It deals with the identi- 
fication of trees ; their nature, habits and 
growth ; insects and diseases which attack 
them; their grouping and planting; the 
pruning and care of trees, and forestry in 
its many aspects. 
The treatment is concise, systematic and 
free from an undue use of technical bo- 
tanical terms. The author’s aim through- 
out is to give only the salient points. 
This, together with the form in which the 
text is issued, renders these studies espe- 
cially valuable as a guide for practical 
field work and for observations and note 
keeping in the field. 
The size is planned to fit the usual 
SxlOG-inch commercial note book cover. 
The manual may, therefore, be convenient- 
ly carried on field excursions together with 
a supply of paper for notes. 
The pamphlets will be sold separately at 
the price quoted, or may be obtained in 
lots of fifty, of the same or different pam- 
phlets, at a discount of 20 per cent from 
the list price.
