culverts and bridges whon Uioy got
old. With the matorlal used tho
first cost Is tho only cost, No pains
havo been spared In protecting tho
new grudo from tho destructive of
fecta of wator. Tho surface ditches
carrying the water into the numerous
culverts without lotting It run down
the slopes is a big protection. Also
tho slopes aro made flat enouen so
that thoro will bo very Httlo slough
ing off and filling tho road bed.
This, road is 24 feet wide, has a
maximum grade of six per cent and
maximum curvature of 100 foot rad
ius, on open curves uud 150 feet on
blind curves. J. W. Sweeny of
Portland was tho contractor.
This road connects with the Cali
fornia section of tho Pacific highway
which was also built this summer,
along similar Hues,
In choosing tho kind of pavement
to bo laid between Ashland and Con
tral Point, Mr. Uowlby had in mind
the cheapness of pavomout or first
cost and tho dogrco of permanence or
maintenance cost. Thoro waa ap
parently no question In the minds of
tho votors but they wnntod a pave
ment wnich tho autos und iron tired
vehicles would not destroy In a short
tune and it was just as apparent that
they did not expect to pay out largo
sums In tho futuro each year for tho
repairing and maintenance of the
road. Wltu this in mind he decided
to put down a Portland Coinent con
crete pavement, later In tho year op
position tp. this pavement aud the
cost bocamo so strong among a cer
tain class of tho taxpayers, that the
dlstauco from tho county poor farm
to Ashland, 4 V6 miles, was let by
contract fpr usphaltic concrete. Tho
argument of the parties protesting
against the Portland turnout concrete
was that tho asphaltlo concreto would
bo nearly as good and cost much
loss. However, those who aro fa-
HiIh grade lint n maximum grade of
blx per cent, n minimum radius for
curves of 200 fert, anil In free from

' miliar with tho history of pavemonts
of other parts of tlio country, reallno
thnt no other pavement however
well It may bo laid, has tho wear
ing, onduranco, or ago-renlstlr.s qual
ities of a well laid Port'and cement
concrete. 'Tho surface will wear In
timo, but tho concreto us a baso for
thin wearing surface Is there' for
eternity and becomes stronger with
age. As for cheapness, tho con
tractors havo to guarantee their
pavement for f Ivo years and the cost
of this pavement, the cheapest which
thoy would guarantee to laBt for
flvo years, Is shown on pago 13 t
the comparative costs and whether or
not It Is tho cheaper pavement may
bo Judged.
Tho nsphaltlc concreto uxtends
from the foot of Farnum hill to the
poor farm just north of Talent. This
pavement is five inches thick and 1C
foot wide. From tho poor farm to
Medford the pavement is six Inched
thick, 1C feet wldo and consists of
Portland comont concrete. Also tho
pavement from Medford to Central
Point Is of Portland cement concrete.
Tho asphaltic concrete way laid
by Clark & Henry Construction com
pany, contractors, i V miles, while
tho Portland cement concrete b
miles, was laid by tho county' and
state direct, without letting by con
tract. This was not let by contrtct
becauso of tho extrome amount of
caro required to put this pavement
down right. For Instance by the
omitting of a bag of cement here and
thoro, or by cutting down the Sum
