grade and then cut 1t back to the line.
This renders it firm and unyielding to

In the construction Of a gravel road
1t Is specified that 1.-The first course
shall consist Of good. clean gravel, not
less than so per cent Of gravel, the
balance material that will bind. No
loan will be allowed.
1.-The gravel shall range from pea
stone to three inches ut its longest di-
ameter. Care must be taken to have
the gravel as near uniform in quality
as possible, avoiding sand, the small
sizes to predominant. The gravel
shall be spread on uniformly and roll
ed down. after which sprinkler shall
be used and this course wet down and
then rolled again and continue rolling
until it is firm and thoroughly COM
pacted. This course shall be three
inches in depth when complete after
rolling.
After the first course the second
course shall be put on, and the same
method shall be pursued in its treat
ment Ia every particular as described
for the first course, except that the
size Of the gravel shall not be larger
than will 60 through two inch
screen. This course shall be three
inches in depth after rolling.
AFTER the contractor has taken out
all wheel and foot marks on the Sec
ond course and has finished rolling he
shall then put on the last or finishing
course, which shall consist of 60 per
cent Of stone and 40 per cent OF bind
ing material No stone shall exceed
one inch longest diameter. This course
must be spread with shovels either
from the wagon or from the gravel
dumped on the shoulders. The con-
tractor must not dump the loads Of
gravel on the road proper. This course
after being spread uniformly shall be
wet down and rolled, and the wetting
and rolling shall be continued until
the road is solid and firm and will not
show the mark Of hOof or wheel while
driving over it."
There are many miles of gravel

hard smooth and durable surface.
On this official tour Of inspection
there was included stretch Of telford

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 "the
bed stone shall be OF the following di-
mansions: Six to ten inches in width,
eight to eighteen inches in length and
eight inches deep, placed by hand,
broadcast surface of depth of stone
placed down and stones laid in courses
across the road, all joints broken and
all interstices chinked in and wedged
with broken stone. All sharp points
of stone must be broken off with the
hammer to bring the surface of the
bed stone true to grade. The bed
stone should be laid up full and strong
so as to allow for all settling in roll
ing. In no case will the contractor
be allowed to use stone that is not up
to all these requirements. After bed
stone has been laid, chinked and
broken off to grade the roller shall be
run over the bed stone until it Is firm
ly bedded 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
inches over all after rolling and must
be broken trap rock unless otherwise
specified. The stone used for this
course shall be from three fouths Of

The size Of stone for this course must
be strictly followed to the letter, no

parture from the size specified will be
at 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
ings, including dust mo screenings
larger than one-half inch stone will
be allowed), shall be used as finish
ing course. The screenings after roll
ing has been done on the last course
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 filled and then rolled
down firmly. Then screenings shall
be scattered dry over the surface so
