what NAV be accomplished in concrete
and bitumen roadway construction may
be seen in the court of the ID. hacA-
field & Co, Ltd, building. No more
perfect and permanent surface eoui"
be devised. Notifications would DC
required where animals were driven at
speed. For motor vehicles, the surface
is perfect.
SIDEWALKS.
Under what theory municipalities sur
rendered the space beneath the side
walks, public property, to the use Oh
abutters is hard to understand, except
that public economy gave way to prl-
waite convenience and permitted SIDE
walks to be pierced full of coal holes,
gratines and sidewalk elevators.
Undoubtedly convenience started and
precedent has continued the custom
thereby depriving the municipalities
of a most convenient, continuous space
for the accommodation of and access
to certain public utilities. Correction
on old streets and installed utilities
NAV be at present impossible, but not
so in new streets or future utilities IN
stallations.
PUBLIC UTILITIES UNDER THE
STREETS.
Why. in the evolution of streets, GER
tain public utilities should have been
placed in sundry trenches in all sorts
of locations under the surface or the
street is almost mystery and per-
version of common sense and mun1-
cipaI and corporation economy.
| A little table of calculations will cas-
lily illustrate the economic points, as
| follows:
MUNICIPAL EXCAVATIONS
CROSS SECTIONS.
Water mains, trench 2 1-2 #. by
| fit. equals Is so. fit.
Sewers, a trench 1-2 TT. by it..
| equals 10 50. TT.
storm sewers, a trench 2 TT. by #.
| av., equals 10 so. #.
Government total-40 50. TT.
UTILITY CORPORATIONS.
Gas mains, a trench 2 #. by TT.
| equals 10 So. TT.
Electric light and. telephone, trench
2 IT. by it., equals 10 So. fit.
Corporation totals-20 so. TT.
Total cross section area-60 50. TT.
A conduit, excavated under side
walk, avera ging for grades eft. by IT.
would accommodate every one of tn
above utilities and give a clear runwa!
of 8 #. by II #, for access, for re
pairs, etc, the total area being al
original saving of Is so. TT.
We do not bring into consideration
the lateral excavations or excavation
for repairs and renewals.
The passageway itself would make
; storm sewer of great capacity and on
that could easily be flushed out an
cleaned.
UNDISTURBED STREET SURFACE
With utilities as now placed, wha
opportunity is there to establish o
maintain a perfect street surface?
is doubtful if anyone will claim the
can be so maintained, even if the con
struction is perfect.
HARMONY OF PURPOSE AND AC
TON IN MUNICIPAL DEPART
. MENTS.
I No reference is intended to local gov
eminent, but to the general aspects c
the various departments of muntcipal
ties throughout the country.
1 think l am within the bounds c
) fact when l state that as rule stree
, departments have no direct or COOP
erative connection with the water de
partment, nor with the sewer depart
ments, nor these with each other.
Each department acts independent
and both water and sewer department
combine to destroy the work OF Tn
street department as suits their partie
ular purpose at any time their cor
venience requires. Public franchis
companies, restrained only by the stiE
ulation in their franchises, that the
{ repair all damage they do to street
