Advice on tree planting for cities
and towns that Is applicable to PEN
dleton and the growing towns in the
west end OF Umatila county as well,
was given Attorney II. S. Blanford Of
Walla Wala In answer to a letter re-
Gently written the Smithsonian Instl-
tute at Washington regarding the
treatment OF city trees In letter from
George b. Sudworth, dendrologist in
the forestry department, to which
the matter was referred, In which
the latter recites a few points TO be
observed In the care Of city and town
trees. "Fast-growing trees" he
says "such as poplars. silver maple,
etc, which soon get beyond useful
size, especially when placed In mar
row streets, require cutting back to
keep them within bounds. while slow
growing and long lived trees will OF
course not require this attention.
In selecting trees for use In parks
and streets Mr. Sudworth goes on to
say attention should be given to their
life and usefulness Short-llved trees,
such as the poplar and silver poplar.
should be used only for interplant-
ing between the long-lIyed ones which
are to serve finally. the short-lved
ones being taken out as soon as the
others have come into sufficient size.
TIL irrigation OF city and town trees.
the dendrologlst thinks, is matter Of
special consideration and each sltu-
alton needs to be worked out upon
its own special merits. II Is possible
he believes. TO supply water regularly
to trees through the placing Of tiles
near the trunk and by connecting the
tile which sinks to the root of each
tree with n surface run Of tiles. The
water let in at the upper end OF the
street will then supply long line Of
trees.
Pruning and other care OF orna-
mental tres Is thoroughly discussed
and explained IN an article enclosed
with the letter, and is printed In full

Kinds of Pruning.
In order To- secure certain very Inn
portant results. II is necessary to
prune shade trees at stated periods.
The necessities for pruning shade
trees may be divided under three
heads:
U) Removal OF dead branches,
(2) Of living branches for the pur-
pose of relieving encroachment upon.

The important requirements follow
ing pruning for these purposes is that
the wounds should heal promptly.
This will be attained best by cutting
naples and birches during October
November and December, and other
trees from November to April
Wounds made later will lose a full

go Heading-in, or severely short
ening the limbs to secure new top
growth. The trees which may require
and will endure. this treatment are
mainly poplars willows silver maple,
sycamore, locusts and tulip trees.
The most vigorous and fullest
growth OF new top shoots will be Sc
cured and prompt healing Of wounds
about by cutting the tree before or at
the time spring growth begins. Naples
and birches should be cut during Oc-
tober and December; If cut from jan
uary to April. the wounds are likely
TO flow sap to the injury of the tree.
other species may b cut back from
November to April. The new shoots
resulting from pruning during these
periods have the great advantage OF q
full seasons growth. which likewise
hastens. to the fullest extent the
healing of wounds.
Manner OF Pruning.
Limbs destined to be removed en-
tlrely should be cut close TO the trunk
or other point OF origin In taking
off limbs OF considerable size an un-
dercut should always be made first,
in order to prevent them from split
ting of sdllvers of bark and wood from
the trunk The main body OF very
heavy limbs should be cut off at a
point several feet from the trunk, af-
ter which the stub can be amputated
without damaging the trunk. The sur
face of the wound should be brought
in line with the general contour of
the trunk. No pains should be spar
ed to accomplish this, The surface
of the cut should be smooth, all rag
