.tions made by Congress for the plaza

islands or parks created by such i'm
provement were transferred from the
Jurisdiction of the Commissioners to
the Jurisdiction of the chief of engi-
necrs. United States Army, on August

2. Surveyors Office.
a-The work done by the surveyor is of
two classes, namely, that done for pri-
yate parties and that done for the Dis
tTict of Columbia and the United States.
The total amount of fees collected dur
ing the year for private work was S12,-
S17.95. The amount received during
the previous fiscal year was S13,5S5.9O.
The amount of work done for the
United States and the District of Co
lumbia showed large increase over
that of the previous year. Among the
larger projects undertaken were sur
veys and locating lines for the District
Yorkhouse at Occoquan, Va, and sur
veys in connection with the project for
the reclamation and development of the
Anacostia river and flats.
Under the appropriation of $4,000
made for surveys of old subdivisions,
such surveys have been made of square
1888, Mills avenue and West Wood
ridge. Wisconsin avenue from George
town TO the District line, Georgia ave-
nue. from Florida avenue to the Dis
triCt line, Benning road and many old
boundary lines along the Anacostia
river. One hundred and fifty stone
monuments were planted, marking the
boundary lines of subdivisions in these
localities, and many more will be plant
eti when the Anacostia river survey is
completed. The work is very useful in
executing private surveys. and the ap-
preparations made for the work are
amply justified.
Street and Alley Extensions.
During the year, IS street, alley
and park condemnation cases were pre-
pared and filed. At the close of the fis
cal year there were sixteen such
condemnation cases in court. in IA of
which yerdicts were rendered, and in 2
others the cases were dismissed. Some
of the most important work was in
<a0T1 . cot inn wit tna <,f
ming road, the widening of Georgia
avenue from Rock Creek Church road
to the District line, the widening of
cathedral avenue and Woodley road
from Connecticut avenue to Wisconsin
avenue, the widening of Minnesota
SIenue southeast, the extension of 18th
street from Spring road to Colorado
avenue. and several connecting streets.
II
u Trees and Parkings.
The number of trees on streets. in
school yards and on Fairgrounds at
the close of the fiscal year was 103,135
The trees planted during the year
spounted to 3,3ss, and those removed
1886. making a net increase during the
year of 1872
The number of trees on the streets is
1gs.S1S. and the mileage 5S4.1S. The
trees are planted on both sides of the
streets. and the mileage is figured on
the basis of 352 trees to the mile. The
mileage of the streets planted with
trees at the end of the year was 1920
the amount expended for the plant
a1g and care of trees was s43,376.21.
The varieties of trees planted were
sim, ash, gingko. lindens. Norway,
sugar and silver naples. pin and red
oaks, sycamores and poplars.
Coordinate with tree planting,
large number of seedlings of various
Kinds were planted in the nursery
These seedlings, when they have at
tanned their proper growth, which is
n ABOUT four years, are used for street
planting. 1t is estimated that from
$4,000 to $4,000 young trees will be in
the nurseries ready for planting during
the next four years.
But little progress was made in the
general trimming of street trees, on
account of the smaIlness of the ap-
Ryopriation available for the purpose.
At the beginning OF the year many
frees were found infested with insects.
such as the tussock moth and web
worm. These trees were SPRAYED, and
the egg masses of the tussock moth
purnt from the trunks SO as to pre-
Efnt Matching. In April all the elms
Sn the city streets were sprayed with
arSenate of lead to prevent the de-
struction of foliage of this variety by
the elm-ieaf beetle. The lindens were
also sprayed TO prevent their defolia-
ton by the web worm and the elm
leaf beetle. The work done gave very
satisfactory results. and the trees are
rl very good condition. The unit cost
OF spraying is trifie more than I
CENTS per tree.
etn addition to trimming and spray
pis, cavities in trunks and limbs of
ihe trees were cemented in order to
save them. This operation consists in
Pie removal OF decayed and diseased
parts, after which the cavity is
cieansed and filled with cement.
In addition to caring for the trees
unfenced public parkings and other
PUBIC space under the jurisdiction of
tHe Commissioners were kept moved
as far as il could he done with the
funds available.
