There are many miles OF gravel
roads within the state of Connecticut
which are as smooth-to use II term
that is becoming familiar as applied
20 improved roads as n billiard table,
and WHOM, after n year or SO OF traffic,
they are given the surfacing OF trap
rock spllnters II is difficult to note the
difference in appearance from mac
adam. This construction affords a
hard, smooth and durable surface.
On this Official tour of inspection
there was included a stretch of telford
construction. Here the travel path
had been cScavatod TO depth OF
foot below grade line, and then the
large stone for the FIRST or bed course
was laid. In doing this class of work
the commissioner requires that 1.-The
bed stone shall be Of the following di-
mensious Six to ten inches I'm width.
eight TO eighteen inches in length and
eight inches deep, placed by hand,

with broken stone All sharp points
Of stone must be broken OFF with the
hammer 90 bring the surface of the
bed stone true 60 grade The bed
stone should be laid up full and strong
! so as 30 allow for all settling I'm roll
! ing. In up case WIN the contractor
/ be allowed to use stone that Is not up
| TO all these requirements. After bed
stone has been laid, chlnked and
broken of TO Grade the roller shall be
run over he bed stone until It is firm
| ~ beddcl and will not kick or rock
under the roller. No nests of small
stone Will be allowed, nor will the con.
| tractor be allowed TO use rotten stone.
The second course shall be four

course shall be from ee-fouths OF
! an inch to two inches longest diane

bins, the smaller sizes to predominant.
| The size OF stone for this course must
be strictly followed to the letter, no
tallings will be allowed, and any de-
parture from the size specified will be
Mt the contractors risk The stone
must be dumped on the sides Of the
road proper or on the bed stone foun-
dalton and be scattered with shovels
to the required depth sufficient to roll
| down to four inches. The rolling shall
be continued until the stones are thor
oughly united firm and solid under
the roller.
THE top course shall be one inch
thick when finished. Trap rock screen
lngs, including dust mo screenings
larger than one-half inch stone Will
be allowed, shall be used as a finish
Ing course. The screenings after roll

Of broken stone shall be carted on the
sides of the road proper and dumped
at suitable intervals, after which all
wheel tracks and foot marks Of horses
shall be carefully filed and then rolled
down firmly Then screenings shall
be scattered dry over the surface so
rs to I'll all interstices, and the roller
shall be run over the surface so as to
shake i'm the dust. Immediately after
n sprlnkling cart shall be used and

more screenings must be added and
sprinkled and rolled again, and the
screenings, rolling and sprlnklng must
be continued until all the coarse
stones have been covered and the in
torstices completely filed and the road
Is smooth and will shed water and
measure In depth one inch Of screen
ings for wearing surface. The con-
tractor is not to be allowed to put on
the screenings all at one time, but
must spread them on as described
above, and he IS not allowed to devi-
ate from the above treatment in any
way. The contractor must not wet
the screenings before they have been
scattered on the broken stone. and,
/ furthermore they must be perfectly
dry before they are put on the road"
1t requires constant vigilance dur
Ing the term of construction to insure
value received In road building. And
one who has Travelled for q day at n
time with several state highway com
missloners appreciates that the office
Is not a sinecure.
