wheels be converted from road rollers
into traction engines It IL possible TO
employ them for all the various tasks
OF operating n stone crIIsher. hauling
the stone to the road and finally rolling
the new made road.
One Of these road building nutomo-
lilies will, when in use as traction en-.
glne, haul load OF at least fifteen
tons Of stone over an ordinary road.
On the other hand, when transformed
into stationary engine for operating
stone crusher, II furnishes sufficient
power TO crpsh any ordinary rock for
use as the foundation Of the highway.
In conjunction with this apparatus the
up 10 date road builders are using n
lately devised and very ingenious
dump cart, with an attachment for
automatically spreading on the road
amy required thickness Of stone.
In this time saving method OF road
building the stone is dumped from the
crusher into the car hauled TO any de-
sired point on the road By means OF
the roller traction engine ana then
spread over the surface undergoing
improvement much more evenly and
rapidly and also much more cheaply
than II could possibly be done by the
use OF men and teams. The dlstrlbut-
Ing apparatus on the dump car can be
80 adjusted that the sheet OF crushed
stone, sand or gravel spread upon the
road will be OF any desired thickness
from one TO eight inches. Attached TO
this odd mechanical worker Is IN en-
glne tender with n device for use in
sprinkllng during the rolling process.
Other new paraphernalia OF great
value In twentieth century road build
ing operations are the complete porta-
BILE rock crushing outfits, including not
only movable rock cruslers proper, but
portable bins on wheels. Some Of these
have folding elevators, which raise the
crushed stone fifteen feet from the
ground, although the apparatus Is less
than ten feet In height when folded,

tain movable plant Of this kind that
Is capable of handling fully twenty
tons OF stone per hour. Finally In the
same category is the portable storage
bin on wheels, which, though large
enough TO hold twelve tons OF stone,
weighs when empty but $500 pounds.
On occasion one Of these entire outfits,
consisting Of stone crushcr elevator,
screen and bin, has been set up ready
for road building inside Of fifteen min
utes.
There have been introduced during
the past few years some very wonder
full road machines which win plow
and grade at surprising angles and will
work quite us well with one wheel high
up on the bank and the other down In

markable OF all, however, is the mar
velous dirt elevator which plows up
the earth and lifts the loosened ma
terial into wagons or conveys II TO the
center OF the roadway. The dirt ele.
vator consists principally OF an ad-
