TREE SURGERY
TAKING FIRST
ROW IN STATE
Many Examples of Saving
Natures Own Pointed to
in City.
DECAY ALSO PREVENTED

Some fine examples of tree surgery may
be seen In indianapolis, according to a
bulletin issued by George II. Morgan,
head of the special service of the city
park department One especially good
piece of such work is to be noticed in
front of the Bobbs Merrill Publishing
Company's plant In East Vermont street,
he states.
The bulletin is as follows:
Injuries of various sorts are SO COM
mon on trees that most people are ignor-
ant of the consequence Of neglected
wounds, or at least they underestimate
the danger. Every wound, regardless of
its size that penetrates the inner bark.
if left unprotected may be the cause OF
the death Of a fine and healthy specimen.
The best and most economic plan to
prevent future decay and injury is TO
treat these wounds as they appear, espe-
cld1ly If the tree Is q valued one
In tree surgery there are a few funda-
mental principles that should be OBJ
served to secure permanently good re-
suits.
Remove all dead, decayed or diseased
and injured wood.
SteriIize and waterproof all cut sur
faces.
Leave the work in the most favorable
condition for rapid healing. this often
means the filling or covering Of deep
cavIeties.
TAKE CARE OF
DEFECTS YEARLY.
Watch the work from year to year and
K any defects should appear they should
be tended to Immediately.
In instances where neglect has been
the cause Of considerable decay it may
become necessary for some cavity filling
TO be done-in such case only as expert
eneed man thoroughly versed in all lines
Of the work should be employed. In
cavity filling the value Of the tree should
be carefully considered, II the specimen
is a rapid growing short lived one 1t Is
hardly worth the time and money spent
in an eudeavOr to save it-but rather
taken out completely and replaced with
an approved variety. In any event.
diseased or insect infested tree should
not be allowed TO remain as menace to
nearby trees which are in a more healthy
condition.
In cavity filing proper the primary
steps are to remove all the decayed or
diseased wood. cutting back TO the live
vigorous tissue. The exposed surfaces
should then be sterilized. creosote being
usually recommended for this purpose;
care should be exercised so as to not
touch the cambium or growing layer with
this solution. as It is Of such sensitive
nature that injury would result.
WOUND SHOULD
BE WATERPROOFED.
After thorough sterilization the
wound should be waterproofed by being
given an application of asphsltum. In
making the cavity. care should be exer-
cised so as 10 not make Il any larger than
necessary. For the filing proper cement
one part. sand three or less parts is
generally used
\ good example Of extensive tree surg
cry work in indianapolis may he seen In
front Of the Bobbs Merrill Publishing
Company, on East Vermont street. At
this place extensive cavity filing has
been resorted to and shows what may
be accomplished in the way Of Swing
trees.
Those citizens who are deslrous OF
receiving information relative to this or
any other forestry problem are urged 10
consult the special service, department OF
public parks.
