generally speaking. even soluble solids

troublesome to be long persisted in

motorists.
RENOVATING CARS
M. S. asks: is it profitable to have
two old cusings sewed together to
make it new tire? There are parties
that claim izreot things for this proc-
ess. _
Answer: We doubt lt. the follow-
ing being some of the objections
which we have heard raised against
the process: The result is it very
thick. s-tiff shoe and one with too
thick a wall, can hardly bend ade-
qiiartely to absorb road irreguiartles

HAT is the policy ot' the Maxwell Motor Company.
It began five years ago on a single chassis plan
and today 300,000 Maxwells have been built on this
program. '
_ Not 300,000 Maxwclls identically alike-~for that would
be admitting that the car has never improved in five years’
time. '
More than 1000 refinements have been made in the
Maxwell. .
But the original chassis plan was not changed. It has
simply grown better as the days went by.
The logic of building one thing and thus building it
well is too clear, too sound, too emphatic in results to argue
against. _
Like any line piece of machinery the Maxwell seems to
improve with age. ‘ ‘
It runs on and on without end. We have never heard
of a Maxwell salvaged.
There is no car with a better road ability record. And
it saves many a thrifty dollar by shying.at the repair shop.
This Maxwell you see today is not a new, Maxwell;
. though many persons have thought so. It has been so much
improved in appearance that our contemporaries in the trade
repeatedly refer to it as the new Maxwell. ' ‘
However, good looks have not in any way handicapped
its running. And the latter is the main thing, after all, in.a
motor car.

Balanced Value
Value, as represented in Gray DortiMotor Cars, is a union
of good qualities. _
Jtrengtb that means faithful service, free from trouble, yet
sacrificing nothing of the Iightn ess so essential to economy.
Beauty unquestionable, that yet allows for every efisential of
good engineering. Comfort, too, both in riding and driving.
And then a price kept surprisingly low by factory efficiency and big
production.
You need in your car all the qualities_ the Gray Dort has. _And pro-
bably you need nothing more. (lcrtaiiily you can get nothing more
without paying very much more.
The touring car is $1245; thc Gray Dorf Special ~~ the car with added roilnementl ini
extra equipment, is $135 extra; thercnre also ii coupe, and a sedan. All prlcen,f.o.b~
