the run lying south of the main sewer and pro-
between X and NJ streets This sewer Is so
large in its dimensions that q buggy can be
driven through il with ease.
FROM lnls generai statement OF The system 81
man sewers adopted and carried into execution
an idea may be formed of the magnitude of the
work accomplished in this direction during the
past year. The following is an exact statement
OF the main sewers laid November l:
2,4i3 lineal feet of Tiber sewer, 80 feet span.
5,2C0 linesl feet of B-street interceptng sewer,
IL feet span.
1900 lineal feet OF Slssh-run sewer, 10 feet
span.
q ,OS7 lineal feet of brick sewers, from to 9
feet III diameter.
Or about eight miles of main sewerage.
About seventy miles of tile sewer have been
and are now being laid, as will Ice seen by ref
erer c. TO the tabulated statement accompanying
this report.
WATERWAYS.
The improvement OF the caTriageways of the
city and the change OF grades adopted, have in
volved the necessity of extending the water
mains connecting with the Washington AQue-
Guct in some instances, and in lowering the
mains already in existence in others, amounting
in The aggregate to about thirty one miles, a de-
"a led statement OF which, together with the
FalUable report Of the water distribution in tie
cities OF Washington and Georgetown, will be
found ~ the accompanying report Of ths Water
Registrar.
GAs-NATNs
The gss-mains laid and altered bv the Wash
iDgtOn Gaslight Company during the past season
aggregate about forty two miles, and the ROar,
take great pleasure in recognizing the prompt
and satisfactory manner in which that company
have acted in furtherng the improvements
inaugurated.
STREET PAYMENTS
The Board have endeavored, in the matter OF
pavements for carriageways, TO adopt all the
most approved varieties in use, and " tn this
view have laid them in about the following
proportions:
"a % miles of treated wood pavements: Bal
lard, Miller Stow and others. The most
Of these are either finished or under
way and so far advanced as TO ensure
their completion this season.
5o5 miles OF Philips round block pavement.
O.SI miles of compound wood and concrete
pavement.
1880 miles of concrete pavement.
4.ol miles OF Belgian and granite psvemsnts.
0s miles of MacAdamized street.
6.I6 miles of cobbestone pavement.
80 % miles of graveled streets and roads,
mostly in county,
1886 miles ofimproved carrisgeway pa vements
assuming the same as 81 feet wide.
Of these there are
1872, 9o3 yards of wood pavement,
3o6,I6l yards of concrete pavement.
223,O51 yards of granite and MscAdamizei
pavement.
12s, 9c5 yards of cobblestone pavement.
1888 yards of graveled streets and roads.
1892 $50 yards.
OF the asphalt pavements the following have
been laid, VIZ: The Scharf, Evans, Scrimshaw
or Abbott, and the PsriseR. The results thus
far observable show but little difference in the
quality and durability of the respective varieties
named. Where the material has been improp-
erly heated or burnt, or where il has been laid
in bad weather, the results have been unsat's-
factory; bIt the Board are Of opinion til at, when
properly heated and laid in good weather, this
description OF pavement is one of the best, l.
not the best, now in use. Certain it is, that
should the top coaing give way a very slight
expense will replace it, the foundation or road
bed proper remaining unim paired, and in fact
impeTishable.
In the matter OF wood pavements, the follow.
ing varieties have been laid:-The Stow, Miller.
Morse, Ballard, Peyton, Perry, DE Golyer Mol
DE Golyer No. 2, IngersOll, FOllansbee, and Kew
stone. These payements have been treated BY
three processes-the SeeIey and Robbins both
creosoted,) burnetiZIng, and the Samuels pro-
cess, all OF which have been largely used in
other cities. These payements, with the eNcep-
ton of the Follsnsbee, which was laid under a
contract of the old Corporation, have nearly all
given satisfaction, and will compare favOrably
with wooden pavements laid in any other city.
The durability of this class of psyements is a
question upon which differences of opinion are
but the experience of other places
prove that, when properly treated and OF good
patent, they will last at least from ten to fifteen
years. The round block is a cheap pavement,
and when laid of juniper or cedar wood costs
about One-half as much as treated wood. 1t il
laid upon gravel and sand foundation, with no
tar or binding material except gravel. This
pavement, so far as laid, has proved entirely
satisfactory, and the Board is of the opinion
that tor a large number OF our streets it is
most desirable pavement, ombining az il does
Cheapness, smoothness. and durability.
OF compound pavements the Board have laid
that known as Hayes patent on 18th street,
between Pennsylvania avenue and b street. IL
Is laid upon bed of asphalt, is OF square
wooden blocks, treated, and covered with a
csstirg Of asphalt. so as TO be impervious TO the
weather. The Flanagan pavement has been
laid In Sd street, from Pennsylvania avenue to
Indiana avenue, and is somewhat similar 10 the
hayes pavement, except that the blocks are
round, OF chesenut or cedar, and untreated.
The tTap-rOck or Belgian is too well known ~
require any particular mention here. and is a
very durable and cheap pavement. The gran
lie block pavement laid by the Board has been
mostly furnished from the Guarries near Rich

the traI-rock or Belgian from twenty t. forty
cents Per yard.
Cobblestones have been laid in streets on
which the travelwould not justify a very eXp5n-
sive pavement, mostly south OF Pennsylvania
avenue, and at comparatively slight expense.
The MacAdam road has been used on 4,

IN the county, and has been there extensively
used.
FOOT PAYMENTS.
The board have in most instances adhered to
the brick foot pavement heretofore in use in tn
District, mainly on account of its cheapness, as
II Is about IS x per cent less than that of the
cheapest OF other descriptions. A considerable
quantity, however, OF concrete fOOtwsiks has
been laid, which have generally proved sstisfsc
tory. The board have been delayed in finishing
tins class OF work or account Of the scarcity OF
bricks, the demand being far in excess of the
supply, and have exhausted this market and
Drawn very largely from the neighboring city OF
Baltimore. An objection exists on the part of
prOperty-owners to the concrete sidewalk, which
IN the judgment of the board Is ill-founded az it
Is much more durable, elastic and smooth than
the brick footwalk; and were il not for the diff
ference in price would undoubtedly supersede
the latter.

sidewalks laid by the board:
