I The one thing necessary 70 a GOOD
/ road-carth. gravel, macadam or paved
/ is through drainage Of the foundation.
I Money has been misapphcd in road
/ making because Of neglect Of thorough
T drainage, even when the monev has
/ been used TO build roads OF a material
that should give them a permanent
character On the western prairies.
whore the natural drainage is poor. un-
drained gravel roads have suddenly be-
come mud roadswhen put to the severe
test of Il long rainy spell in winter and
early spring Not the least unfortunate
result of this has been prejudice
against gravel roads in particular and
a scarcely less pronounced distrust Of
permanent roads in general. Lack Of
drainage was the real cause Of the fail
ure.
Whether the road is to be of earth.
gravel or macadam the earth roadbed
should be graded, browning it twelve
to fourteen feet wide and twelve to
eighteen inches higher in the middle
than at the edges. Along each edge
should be cut shallow ditch. This is
a correct general statement. which
of course should be modified to
suit peculiar circumstances. Thus
in very hilly country, es-
pccially if the soil washes easily,
the bitches should not be cut at the
sides, as they are not necessary, and
will become serious gullies. In hilly
country it is not necessary to crown the
roadbed 50 high, but the browning must
always be sufficient TO insure ready sur
face drainage Twelve to fourteen feet
in width is sufficient Making the road
wider has Ducn found a needless ex-
penSe.
With those soils and subsoils special
~ well adapted to drainage. crowning
the roadbed and cutting the bitches at
the sides will secure the necessary
drainage; but where the soil and sub
soil are not favorable TO drainage adj
citional measures must be taken. In
the country in which l reside gravel
road has been made for twenty miles
near the Mississippi river bluffs This T
road Is on soil and a subsoil decidedly f
gravelly giving splendid drainage.
This gravel road is now eighteen years
old, and has proved satisfactory The T
only means taken to secure drainage
was to crown the roadbed little in |
low places To make gravel road in
this way over the greater part Of the
same country would be a waste Of
money, for in most places the soil is
black prairie loam. and the subsoil a
tenacious clay
1t has been found quite satisfactory
in most localities, having a black sur
face soil and clay subsoil, to lay a dram
of tile along each side, near the edge Of |
the roadbed. This has been found a
better location than near the middle Of
the road The Office of the tile is
TO carry water brought up from be-
low rather than water sinking in from
above. In some localities it is neees-
sary to use three drains one line of
tile beneath the center of the roadway
and one under each ditch at the side.
1t seems unnatural to put the tile I'M
der the side bitches, but this location
has been proved best.
When the roadbed is to be graveled or
macadamized the browning earth foun-
dation should be nicely smoothed and 7
then rolled until quite solid. 1t is well,
also, in tins case to put the clay subsoil |
from the bitches on to the surface |
When rolled it makes a hard, smooth +
surface, almost impervious to water.
and over which will flow, off to the
bitches at the sides, the rainwater that /
may sink through the gravel or mac
adam. When the surface is to be of /
earth only the clay subsoil should be
kept underneath, and the natural soil /
be placed on top. The surface soil will /
usually afford much better drainage
than the subsoils, and make better
road surface. American Agriculturist
