A NEW MAP OF THE CITY.

A Typographical Nap Showing the
Sewer " ater Pipes and all Sub
Surface Works.
Mr.. John W. Howard, draughtsman in
the city surveyors office, has nearly COM
pleted a most valuable topographic map of
the city, the largest ever drawn. 1t is 12x7
feet, and is so near completed that the Ioca-
ton of the sewers and the water mains of
the CITY may be ca silly obtained by a glance.
The work was begun in Sc tember, but ow-
lug to the pressing demands on the Office
from the various departments Of the city,
the work on the new map has not been con-
tinuoUs, but has been done at odd times.
As the maps in the water works office,
drawn at various times, show the location
Of the mains, City Surveyor Winn ad-
dressed letter Sept. % last TO the late SUI
perintendent of the water works, Mr.. Alvin
n. Miller in which he said that in order to
secure accuracy in the new map he desired
such Information as to the size of the
mains, taeir location in the streets, whether
in the center or on the north or south side
in streets running east and west or whether
on the east Or wes5 side in streets running
north and south; the location of the valves,
the distance from the street corners, and
tho position OF the fire plugs, as would en-
able his draughtsman to accomplish the
proposed Nork.
As a result of the information received
from the office of the water works and in
other directions, the map shows the exact
location of the water mains, the fire plugs,
stop valves, all the fountains, the reservoir,
in short everything pertaining to the water
works in the city. Full information will
be given in marginal notes which cannot be
shown by drawings. The siz3 of the mains
will be designated by colors 1t will show
all the connections, and it is the intention
10 show what sections OF the city certain
stop-cocks will shut off the water. Each
sscCion is to be designated by particular
color on the map.
In the way of sewers, the map will show
the location of existing sewers, and the
future sewerage system, as soon as plans
are decided upon. lt will show all man
holes and sewer traps, the grades of the
sewers aud the depth of each below the sur
face 1t will also show all open drains and
what bitches draiA the city on east, south
and west. The topography of the outlying
lands in the immediate vicinity of the city
will be shown. The profile recently made
by corps of engineers OF each street aud
lane for the guidance OF the committees
which are consid ring plan for a house
drainage system will be utilized in showing
in the new map the elevation of the streets
and lanes. L shows all the squares of the
city, watch, with the streets aid lanes, will
Ue de ignated by letter.
The map has been drawn with view to
adding from time to time new sewers, aud
sewer aud water mail extensions ETC. The
new map will not only include ali the in
formation to be derived from various other
city maps and special maps OF the different
city departments, but will. as has been
seen, embrace much new information for
the guidance of those who will have oc--
casion to refer to it often. It has been
drawn TO an accurate scale of 100 feet 10
the inch, making it four times larger than
the ordinary CITY map.
When flnis sled, the new map, which will
be handsome y colored and mounted, will
be given q place in the mayors Office for
the better accommodation of the mayor.
aldermen and city officials, who will have
gre ter occasion to consult it. City Sur
veyor Winn, in exhibiting it to a MORNING
NEWS reporter, yesterday, said that it re-
fleets tue hgbost credit on his draughts-
man, Mr.. Howard, who has been painstak-
ing and accurate, and that the map, when
completed, will not only ne the largest map
of the city ever drawn, but it will be the
most valuable, bee use it embI ac4s so much
that has not heretofore been feature of
city maps. AS a record Of the street SER
vice it will be invaluable.
