REVIEWS AND NOTICES OF BOOKS. 135 
No one recognises more fully than does the author of this review 
the difficulties which have to be faced in a work of this sort, 
more especially in genera such as U/mus, Populus, and Salix. 
Professor Ward set himself a difficult as well as a big task, and 
if he has fallen short of the ideal which he fixed for himself, 
the shortage must not be measured by itself; it must be taken 
with the whole, and by contrast it sinks into an insignificantly 
small proportion of it. All interested in this important branch 
of botany will join in regret that its talented author was 
not spared to complete his work. Ars longa, vita brevis.

Deparimental Notes on Insects that affect Forestry in India. 
Part III. By E. B. Sressinc, Forest Entomologist to the 
Government of India. 
This is a continuation of the notes that appeared in 1902 and 
1903. 
The present volume, extending to over one hundred pages, is 
a record of excellent observational work on forest insects in 
India. ‘Thirty-two different species of trees are noticed with 
insects infesting them. Some of the insects described are new 
to science. The notes on life-history and habits cannot fail to 
aid greatly those concerned in forestry in India, the more so as 
the descriptions—unless where technical terms are absolutely 
necessary—are in easily understood non-technical language. 
An additional feature of the volume is an excellent set of dight 
full-page plates illustrative of insects themselves and of their 
damage. R. S. M.
