REMOVING DECAYED MATTER.
THE TREE SURGEON.
tic l r scs Cement to Offset Ravages
By Clifford H. Easton.
I am frequently asked the question: "What i 3
tree surgory?" In so fnr as it applies to the
tement work alone a good answer would be that
k is the practical application of dentistry to
bees. But this answer would not cover the
Jnany other branches of the profession, consist
kig of trimming, chaining, packing, scraping,
graying and fertilizing. Tree surgery is. in
feet, an advanced development of arboriculture.
Both fruit and shade trees are valued now as
hever before, and the fact has become generally
Known that by skilful methods of the tree sur
geon it is possible to givn a now lease of life
Jo trees which apparently had reached their
limit of existence. I believe it is safe to say
thai almost any tree of medium age may be
saved by these methods.
Of the many branches embraced In this work
"lio cement filling forms by far the largest and
yo.'-t important part. The practice of filling
•avities with cement has long been in use, but
When carried out along the usual lines it only
served to add to the original trouble. The
n;i thod of staling up the decayed section simply
iiK reased the decay. Many examples may be
a en where the bark at the side of the cavity
was covered by the cement, no regard having
bei n paid t.> drainage or the subsequent healing
of the wound. As the cement did not stick to
t!i<' wood and the swaying of the tree by the
wind often enlarged the crack between the wood
and the filling, water penetrated behind ihe ee
m< i:i. and il' cay went on even more rapidly than
b ; re
The tree grows in girth by the deposit of a
thin layer of new wood between the wood and
bark. Th« re are three layers in this coat— the
middle one being composed of thin forming tis
fcuts known as the "cambium." The inner side
of this layer forms new wood, the outer new
bark. It is this new layer and the layers of the
four or five previous years which are known as
the sapwood, and form the active section of

the trunk and branches. The cells of these inner
rings are gradually covered by the yearly de
posit of new growth, and from living sapwood
become heartwood. which is dead, and serves
merely as a strong framework for the living
parts of the tree and as storehouses for excess
This is the reason why hollow trees may often
be found in a flourishing condition when the
heartwood may have entirely disappeared.
However, a landscape tree in this condition, de
prived of the shelter of its fellows, is in grave
danger, for a high wind or a heavy snowfall
may find it an easy victim.

VILLAGE OF CONCBETI

A member of the Authors' Club had cn!y %

urban village. He had decided that a change
scene, especially a change to a .;■ where tt,
sun shone across the "closely cropped law..
when the wind was not "sobbing among tv|§
pines" and the rain "beating- against the wiasfci
panes"— would freshen his inspiration. Havi^

atmosphere it must be written among the rig:"-'
surroundings. While looking about for this it
mosphere he had discovered a fireproof and as*
quito proof village in New Jersey.
This village, embowered by pretty trees, tot
truly what was claimed for it— the twenties
century village. It was fireproof, as all the at
vertisements had said, every house being of cos- ■
crete construction. No suburbanite riding bd%

would never furnish an item of this character
for the papers.
There were other reasons why the villa*
would not be likely to be destroyed by ■"■■■ Not

The entire community was heated in the win

As for cooking and lighting it was only a mat

contained no stove. All food was cooked on elec
