having elevation ak inches at the center ana

sand or gravel and well rsmmed down The cH'ps
were TO be the bed for the surface paving stone TO rect

The blocks were to be from FIVE TO ten iHehs thick

Of circle, with six inches hight in the center
The stones when thus laid down were 10 be gently

RUSS scheme, formerly described, differs from the
sbove. He lave a foundation Of the broken stone &c
with mortar or cement his pavement Is EMBEDDED IN
the cement with which all the ntersuces and crevces
are aso carefully filed the stones are hammered 90 as

Paris the gutter is Tor misplaced in their middle in
ss celebrated street in ireland where the water runs
across an inclined plane, from one eide 10 foth0 the
highway 10 the county seat OF royal justice being
somewhat ike q Connells judges when you get there
one sided.
Pinkerton's proposal says excsvstc the ground 10
inches below the grade but he tells he excsvates but
a. which Is doubtless found sufficient At this depth
ne paves in the old fashioned way with the round
bowls so long and expensivey kept IN use and IS care
hl to ram down his substratum OF lower pavement
Thoroughly on this foundation be lays three inches Of
sand or gravel and upon the sand he places oblong
blocks Of best grey trspstone granite 60 laid as to
OFFER diagonal joints 10 the wheels
We had no opportunity to see Perrne at work he

inches thick in elastic cement Tor foundation throws
in sand above the tagging TIL within ten inches OF the
surface which is laid in the Street Commissioner
proposa with granite blocks, and covered over with
three inches OF sand.
It's probable that the frost will seldom go below
Perrnes Tagging, ga inches under the street, but
where will the 60 when 1t gets to the nazgng

nearest to the Commissioners proposa-it is cheapest
and may prove to be the best II the wofk Is done
well Both contractors omit the broken stone yet
that toe, might have got trial
few days since, published some remarks by
Maxwell the mschinst, on this subject lie aihrms
that the granite paving Of Edinburgh and Glssgow-
square or oblong blocks as above, hmy Embedded IN
the sand or gravelis found to be durable and eicien

section been contracted for this wen-tried plan as

Our wooden blocks and those in Regent st. London,
are getting deservedy out Of fashion but the Nc

ty on the surface IL instantly mended, as might have
been done with that noble avenue the Third, which
filled with holes because effort was made TO keep
the McAdamzed curve in good order Anstocrauc as
London il said TO be- its streets have infinitely
pleasing equality about them than ours are likely to
have for the next half century, at the rate we are now
progressing The present Minister Of France for For

our country that we stand ready 10 censure any one
who may happen to find fault with the soil or climate
just as if they among the home products OF the

press in New York that is not continually finding fault
with the condition OF the streets, domestic manuisc.

were as bad as 2 years since those Of Paris were
far worse
RUSS plan Is essentially that of Mayor Harper as
stated in his message of Jan. o lsi5
An excavation Is made from gutter gutter 10 the
deph of a inches the space excsvaied lied with con
crete 10 depth OF "a inches nsing toward the center

granite clippings OF granite ballast and sand and tne lime

concrete the foundation for the pavement winch

This would break the surface of the concrete, but merely

rough edges, spreading little at me bottom ana eonosh

heaviest vehicles.
Mr. Harper notices the objection, that II will be din.
cult to take up such pavement to lay down pipes &c
but he admits that in respects, such repairs can
oe made to better advantage than under the present
system for after taking of the layer OF granite blocks
all that is required breach through fourteen inches
OF concrete This Is made without disturbing the sol
dty OF the surrounding and without the risk OF
unsetting the foundation of the street tor some dis
lance around.
The expense 10 the real difficulty We want good
roads elsewhere beside the one in Broadway Perhaps
lew inches OF broken stone and sand below the square
OF oblong blocks if tried in the more democratic Bow
cry would be found 10 answer every useful purpose
instead Of preserving that spacious roadway, with its
round stone pavement in the form OF wholesale man
ufsctory of mudhils and mudholes, sven unto the
third or fourth generation
Were il once decided to pave the City with squared
blocks OF granite instead Of using the smooth round
stones and were such work and labor sttsinsole by
competition under small contracts il is probable that
shrewd cscustors would turn their attention TO the
stacftrs of these blocks, and soon cheaper the
paving process below any thing We yet know OF
