and placed across the street, and upon
which the sections are to rest, are treat
ed with the same preservative process. q
The work of laying is performed as
follows: The street is first excavated


to the necessary depth to allow bed of


four inches of sand; the stringers are
then bedded into the sand and tamped
solidly in place, across the street, SO that
| their surfaces shall be level with the sur


face of the earth. They are laid three


feet apart, from center to center, and con


sequently allow an end bearing for the


sections of three inches each. Thesec-


tions are so laid as to break Joints with


each other. The gutter is formed BY a
higher row of blocks next the curb-stone,


which slopes down to the grade of the
street. ef Ir -le,s :" ui beet 4


Stafford pavement will attract earn


est attention, and the assurance Of, it's


popularity over that Of other pavements


will be found in the durability of the


preserved wood, the strength of its pc


culiar construction, and the ease and ra-


pidity with which it can be removed, and


as quickly replaced, without injury to


the pavement itself, or interruption to


the traffic of the street.a We will explain
how this is accomplished: hus 's.Eod 4


" When it becomes necessary to re-


move the pavement for the purpose of
gaining access to water or gas pipes or


sewers, screw bolts are inserted into the


section, a bar and chain attached to a


jack, and the section is removed and the


earth exposed. If from any cause the


earth should settle beneath the pave


ment. any desired surface can be remov-


ed, the grade restored, and the pavement


replaced, with. absolutely no injury to


the material of the pavement. aaa


again, as otis healthiness and dura-


bility: Wood thoroughly treated with


carbulic acid is proof against decay and


is antiseptic. Thus the garbage and foul
matters of the street become perfectly
inocuous. Expansion and contraction,


by means of moisture, are absolutely
prevented, and the pavement, once laid,


is as permanent as stone and liable to
injury only by reason of mere friction.
Moreover, being framed together, it pos
sesses the highest degree of solidity and
strength, and will resist the action of
any heavy traffic as perfectly as can be
done by any pavement whatever. The
shock and weight of each load is distri-
buted over superficial area of twenty
five square feet, and so divided that no
one point can receive the whole burden.
Another advantage is that whatever sur
face water may find its way through the
joints and cracks of the pavement land it !
is assumed that no pavement is abso-
lutely water-tight), instead of tight
floor, meets a stratum of sand in which !
it sinks, and the wood is left perfectly
drained. Further, as the wood is sub
jected to the preservative process, there
is no occasion for the use of tar and
gravel, which does not in the first in
stance, as with other pavements, make
dirt in the street. a la


"The Stafford pavement is also to be
commended in the fact that the work of
manufacture is all done at the mill,
mostly by machinery, and that, being
composed of large masses, it can be laid
down as fast as it can be brought to the
street, and that the entire process is con-
Quoted with system, speed and economy.
The use of wood for street pavements is
an important event in our public i'm
provements. In the trifing friction
which it offers, SO far as our street loco
motion is concerned, it will do away with
the evil of street railways. With al
broader tire than is used in omnibusses, |
there is no reason why cars may not run
in the open street to carry twenty or
thirty passengers, and thus obyiate the !
Objectionable rail-tracks, which come to
be a serious obstacle to locomotion in our
cities" - .-
