orono, Me, May IA bulletin on
Estimating Timber in the Farm Wood
lot by NJ. Z. Watson, forestry special
list, has just been printed by the EN-
tension Service. In this publication
Mr.. Watson outlines the various meth
DDS of measuring the amount OF stand
ing timber on woodlots Of various
sizes.
The bulletin was written to he used
in con Injunction with the work in tim
Der estimating which MIR. Watson Is
doing all over the State at this time.
One of the chief purposes OF the hulle-
tin is to show the farmer how TO COM
pute the value of his timber so as to
insure him against loss in case or sale.
In estimating n small woodlot Mr..
Watson advocates the following
method:
In a small woodlot an estimate OF all
the trees is most accurate, for each
tree is inspected and the number and
size of the logs are estimated. By
using this method<it becomes possible
to allow for tho defects which some
trees contain. 1t is necessary to aNolo
duplicating the count of measurement
Of the individual trees. This may be
done by the use of piece of chalk or
a light blazing of the bark. In apply
ing this method, the hrcast-heiGht dl-
amctor of the tree should he taken.

hrcastrboirht diameter of a tree. the
