BUILDING GREAT MOUND
AT LINCOLN MEMORIAL
Clark Howard, Landscape Architect,
Here to Study Artistic Prob
lens Involved.

Mound building on an extensive scale
is in active progress at the site of the
Lincoln memorial in West Potomac C
Park. The large hills. daily growing
in size, eventually are to be graded
and nodded into an artistic setting for
the approaches to the classic marble
temple. The large fill at the site is
necessitated by the fact that the base
of the marble memorial is forty-five
feet above the former level of the park
at that point. Under the approved de-
sign that elevation is to be reached
by series of terraces within a cir
cular area having a diameter of 1000
feet.
The exact treatment of this great
mound has not yet been settled. Col.
W. w. Harts. the engineer officer, su-
pervising the construction of the me-
mortal, has engaged the services of
Clark Howard, a landscape architect of
New York, to assist in the preparation
of plans for it's development.
Studying Landscape Problem.
Mr. Howard has reported for duty
and is engaged in making a personal
study of the site and it's environments
including the Arlington national cem-
etery and the Washington National
Monument. He is expected to design
suitable approaches and the size and
character of the terraces.
By means of the terraces the ground
rial will be raised to the same level
as the ground at the base of the WASH
ington Monument. The basic terrace
will be circular in form and about 1000
feet in diameter. How high 1t will
be has not been settled. On its outer
edge will be planted four concentric
rows of trees, leaving a plateau in the
center probably $50 feet In diameter.
In the center of that plateau will rise
another terrace probably sixteen feet
high and 500 feet in diameter. Whether
this terrace shall rise gradually toward
the base of the memorial or whether
there shall be other terraces of vary
ing heights is yet to be determined.
From the main entrance of the memo
rial to the Washington Monument will
stretch wide esplanade fanked on
each side by two rows of large shade
trees. probably English elms, forming
beautiful vista between the struc-
lures.
Two Plans of Treatment.
Two general plans of treatment are
under consideration for the great
mound on which the memorial will be
located. One of these. calling for a
series of terraces of large area, will
require fill of about one million cubic
yards. The other plan. with terraces
of smaller area, will require the use of
about three hundred and fifty thousand
cubic yards of additional material for
grading.
1t is estimated that about one hun
dred and seventy thousand cubic yards
of material already have been deposit
ed near the site of the memorial An
additional supply of about one hundred
and fifty thousand cubic yards will be
procured from the excavation being
made for the foundations for the build
ing for the Department of the Interior
in the square bounded by 18th and 18th
and Z and f streets. BY special ar
rangement with the various depart
ments concerned, the material from the
Interior Department site is being
transported to the Lincoln memorial
site over an improvised railway. The
permit for laying that railway on the
intervening streets and into the park
requires that the material shall be de-
Hvered and the tracks removed within
period of three months
