MODEL ROAD is CONSTRUCTED
Demonstrators at Fair Grounds Show
Crowds How to Do L.


The practical demonstration of road
making was given on the grounds yes
terday morning. The road being i'm
proved is that from the north gate on
Smelling avenue to the rear of the
grand stand. This road Is now. in
very bad condition, and as the heavy
rains have rendered the ground muddy
the work was not begun under as ia
vorable conditions as desirable. The
managers are also somewhat handi-
capped in not having experienced help.
! But Notwithstanding these circum-
stances, the work made considerable
progress yesterday.
The road makers are equipped with
a large number of machines, all spec
tally constructed for road building. The
operation of these machines, especially
the grader and elevator, is interesting
to the spectators. This machine Is
pulled about by an engine and plows
up the surface Of the ground, lifts up
the dirt and deposits it in a wagon
which goes alongside of 1t.
Method Is Explained.
The first thing to be done in making
a road Is to lay it out by measuring
and placing stakes along both sides.
The road being laid out is thirty feet
in width. A plow then cuts furrow
along both sides of the road. The ele-
waiting grader then levels the surface
of the space within the burrows This
elevating grader, mentioned before, has
a plow which cuts layer of soil and
lifts 1t into wagon which goes beside
1t; when one wagon Is filled, another is
ready to take it's place.
The dirt thus accumulated Is carried
to other parts Of the road that are be-
low the grade to fill in. The elevating
grader in use by the road makers is
the Junior New Era" manufactured
by the Austin company, of Harvey, Ill.
The STANDARD Elevator Grader" which
has a longer elevator, is also at the
fair grounds, but is not in use. This
machine is made by the Western
Scraper company, Of Aurora, Ill.
When the surface Is leveled by the
grader subgrade in the center of the
road Is cut. This subgrade Is sixteen
feet in width and nine inches In depth.
1t is made wit ha machine having
blade seven feet in length which can
be reversed to the left or right. This
machine plows the cutters and rounds
the grade perfectly as If planed. The
machines in use by the road makers are
the Western Reversible and the Austin
Reversible road machines.
The road Is then ready for the stones.
The subgrade is filled with rocks
crushed to two-inch gauge or larger.
1t isc finished with fine rocks and
dressed with screenings. Each stra-
tum of this rock Is thoroughly COM
pressed with fifteen-ton steam roller.
The steam roller in use at the fair
grounds Is made by the o. 8. Kelly
Manufacturing company, Of Springfield.
Ohio. ~
Rock Is Crushed on the Spot.
The rock used in the construction OF
the road is crushed by a machine right
beside the road to furnish q repre-
sentation of all the work required in
road building. These rock crushers are
equipped with two crushing Jaws, one
fixed and the other movable, which
makes short but very powerful strokes.
Each stroke is five ighths Of an inch
and 400 strokes are made each minute.
The machine is capable of crushing
the hardest rock. Boulders Of trap
rock and granite are crushed into sizes
ranging from one-fourth inch to two
and a half inches.
The work Is in charge Of the United
States Good Roads association. The
good roads train last year made a trip
from Chicago to New Orleans over the
Illinois Central, making stops and do
ing work in all the states through
which 1t passed. From here the train
leaves for st. Cloud, whence 1t will go
over the Great orthern to the coast.
The members of the company travel
ing with the good roads train are G. H.
Ackley, w. T. Ancil, George w. Stadler,
II. M. Kekjer, H. @. Ireland, N. II.
Paulding, H. L. Deitsch and T. w.
