time when the read becomes
connecting section between trunk
lines or large towns, when the
travel greatly increases to posi-
bly, six hundred to two thousand
cars per day (some of our gravel
roads are carrying that traffic.
when on dry day the dust never
settles when the foliage as far as
can be seen from the road is COW
cred with gray dust, when the sur
face of the road is so corrugated
that when we ride over it we are
reminded of that vulgar but apt
expression, tougher than the
hinges of H" Then, and be
fore then, if possible the road can
be made to carry that traffic by
the application of a bituminous
material. One application of light
oil will not do the trick, but we
have found that two applications
will carry through the season.

the cure all, it is not, but it great

much heavier motor traffic than
we otherwise could.
eve have treated, this year, in
the neighborhood of six hundred
miles OF road with bituminous ma
terial, not always with perfect re-
suits, but with such results that
we have eliminated the rythmic
corrogations and it there is one
thing that will put ones teeth on
edge it is to ride over an apparent
ly good section of road and feel
the old car jumping and skating
like a man waking en- an electric
mat; such is the impression that

good stretch of corrugated wash
board road. My theory, which is
no better than anyone else, is that
these are caused by an excess of
cars approaching the same weight
and travelling the same speed As
you will note that light cars and
Fords travelling % miles an hour
predominant all others and ac-
cording to my theory are the cause
of the beginning of the so called
rhythmic cOrrogarionS. After they
had once started, all vehicles cas-
lily lend themselves as agents to
enlarge and extend the work be-
gun. We have found no cure for
this effect outside of the surface
application of a bitumnous binder,
then the dust nuisance is elimina-
ted, which IS a great satisfaction
to the traveller as well as to the
good people who live by the side
of the road.
As the result of our mainten-
ance program, We have in New
Hampshire today: 1852 miles of
Hard surface road, including bit
luminous macadam, bituminous
concrete and cement concrete;
also 600 miles of surface-treated
gravel ana macaddm.
