able In Building Good Macadam
Roads-Future Maintenance Of High
ways Must Be Mapped Out Before
Anything Else Is Done.
Road building Is now occupying the
attention Of the people TO greater
degree than ever before. Building by
the old fashioned way Is expensive
Tools that reduce the cost are within
The reach of every county. and Oh his
subject IL government report says.
"In addition to the Shovels. picks
and other ordinary implements con
essary. In these days vi hign paid la
Dor and short working hours one rar"
~ hears In this country OF uacndau
stone being broken by hand
There are ma1y kinds OF stone
crushers OH the market Except tu'
city use and in cases where large
amount of macadam work Is done
every year within comparatlveiy
small area. large stationary plants are
undesirable There are several kinds
Of portable plants which may bt
bought at prices ranging from Sl.tiN'
to $500 which are admirably adapt
ed for country use. These plants III

boiler, portable bins. revolving scrts.n
and an elevator to lift the stone afte!

the screen.
1.-The outfits are mounted Oh wheels
and may be moved from place to place
al comparatively small cost. Under
ordinary CONDITIONS from $50 10 500
will pay the expense OF shifting sucl,
u plant from it's old location to new
one several miles distant.
STONE cruShers are variable In their
output They all need much repair
work from time to time on account OF
the severe. usage t" which they are
subjected Win an outfit such as has
been mentioned from eighty to a hun
dred tons tSixty TO eighty cubic yards
Of broken stone per day may he rX
Whted II the rlanr i Kept IN good
condition Such an output Is usually
satisfactory since II single steam road
roller will not often roll more thar
this amount in u day The crnshe'
will take stones which measure up Il
approximately by - inches III eros
section: larger stones require maulin2
before they can BE- placed in the r"
reivine Oritirr
''ln some places II may be found
more economical TO have rhp stone
shipped in from some permanent crush
ing plant than to purchase Il crushing
outfit. and II IL well to consider this
feature carefully 1t should also br
stated that while the first cost of the
road is important. the costs of future
maintenance must also he taken into
account 1t IL sometimes economical
even ut Il greater initial cost to i'm
port stone from a distance If thereby
a more durable road may be had than
Is possible by the USE Uf local stone.
1.-THE cruSher should be set up as
nearly as practicable in the center of
the section to he built: bNt. since much
water Is needed for the boiler. for the
roller and for the watering cart. the
site IL often governed by the location
Of the water supply
TT possible the crusher should he
set low enough no that platform
may be built at the level Of the open
ing which receives the stone This
platform should be sufficiently strong
to bear the weight Of the carts loaded
with stone for the cruSher With this
arrangement the large stones may be-
dumped upon the platform and fed
into the crusher without further lift
ing.
THE wOrkmen who SET up the plant
should have had experience in TINS
work Much depends on the proper
alignment of the several parts. and
will be avoided II the work is done
properly In the first instance.
THE steam road roller is now used
to SO great IN extent that discussion
of its advantages over the horse roller
is unnecessary Macndam roads may
of course. be built with rollers drawn
by horses They may also be bnill
without any rolling except by the
wheels of moving vehicles But expert
ence has demonstrated that 1uirk"i
and better work can be done with the
steam roller ana usually NJ Il less cost
A so called ten ton roller Is sufficient
ly heavy for country roads Most ot
the culverts and many ot the bridges
are too weak To sustain with safety tn
heavier rollers There are several az
cellent makes of such rollers. which
may be- had ut prices ranging from 81
