3. Forest Policy in the British Empire.! 
By j. SiuG: 
The popularity of Dr Schlich’s important text-book is well 
attested by the need for a third edition of the first volume in so 
short a period as seventeen years. The first edition, published 
in 1889, and entitled U¢ility of Forests and Fundamental Prin- 
ciples of Sylviculture, was followed in 1896 by a second edition, 
when the title was altered to Jntroduction to Forestry, and 
enlarged by the addition of chapters on “‘ The State in Relation 
to Forestry,’ and ‘‘The Timber Requirements of the British 
Empire.” The third edition, now before us, shows a further 
change; for the second half, on the ‘“ Principles of Sylviculture,” 
has been transferred to Vol. II., and the name has again been 
changed to Forest Policy in the British Empire. 
As before, the book is divided into three parts— 
Part I. The Utility of Forests. 
Part II. The State in Relation to Forestry. 
Part III. Forestry in the British Empire. 
An Appendix to Part III. treats of “ Forestry in the United 
States of America,” and it seems a pity that a Part IV. could 
not have been added, giving a brief account of forestry in other 
foreign countries. 
A special feature of the new edition of Vol. I. is the addition 
of a number of excellent photographs, illustrating the trees and 
forest work of the chief forest regions of the empire, and especially 
those of India and British North America. 
The Introduction to the volume is an important and interesting 
piece of work. Dr Schlich begins by showing how forest once 
covered the greater part of the dry land of the earth ; how the 
interference of man, requiring wood for his use, or the absence 
of wood for the cultivation of food products, introduced the first 
branch of forestry, Forest Utilisation; how a step in advance 
was made when man required the possession of portions of forest 
which he could work for his own advantage, and so a second 
branch was brought in, Zorest Protection; how, again, it was 
found that mere protection was not enough, but regularity of 
yield was required, and so a third branch was formed, the
