REVIEWS AND NOTICES OF BOOKS. 229 
The preservation of timber is a subject that justifies the 
thoroughness with which it is dealt, and probably most of the 
methods in use are touched upon. Certain of the processes are 
described in detail, and, from the information given, readers should 
be able to judge for themselves of their efficacy. Altogether the 
subject as treated is practical, and at the same time scientific. 
Chapter V. deals with Woodland Industries—estate saw-mills, 
preparation of wood-pulp and cellulose, making potashes and 
resin-tapping. As might be expected, estate saw-mills are most 
fully dealt with, and when it is said that such an authority as 
Mr D. F. Mackenzie is quoted from freely, the subject needs 
little further commendation. Much useful information is given 
on the subject of power, ordinary water-wheels, turbines and 
steam power being contrasted. Saws and other wood-working 
machines are illustrated and described. 
There is little prospect of the wood-pulp industry becoming 
important as an outlet for British timber until our area is much 
larger than it is at present, and until we are prepared to go 
about our business in a methodical way, by keeping up a 
regular supply of timber. 
Charcoal-burning is described, but it is more interesting than 
important, as although much practised in the past, it is now 
done only on a very small scale. 
The other industries mentioned above are not likely to make 
much headway until we take a lesson from our Continental 
neighbours, and set ourselves to make something out of the 
waste that now goes to waste, and learn not to despise the 
day of small things, even if it is only the using of sawdust for 
‘stuffing pin-cushions and dolls.” A. W: Ei

Elementary Forestry. By CHaR.Es E. Curtis, F.S.I. London: 
Estates Gazette, Ltd., 1905. Pp. xxiv+288+ 30. Price 6s. 
As Mr Curtis explains in his Preface, this is an elementary 
text-book not intended to deal with so large a subject as is 
included within the term “ Forestry,” but rather an introduction 
to the elementary study of those branches of natural science 
which have a special bearing on arboriculture, and the study
