C. Vernon Rogers of the Mitchell
terday. He came direct from the home
Office and came west to take charge of
the third annual reunion of the own
ers of Mitchell motor cars. Upon ar
rival yesterday he assumed charge of
the plans. He is more enthusiastic
over the jubilee than ever before The
increased number of owners of
Mitchell cars in California during the
year has been most pleasing to the
manufacturers. The number of ac-
California owners of Mitchell cars
shows that the large attendance of
last year will more than be doubled.
The reunion will take place in San
Jose. All the fun will take. place in
the Garden City. The morning of July
10 will be given over to gymkhana
games. which will start about 10
o'clock.
The hill climb up Alum Rock hill
will be made after luncheon. The
timing apparatus Of the San Fran
cisco motor club will be used. After
the hill climb will come the banquet
During the feast there will be music
and vaudeville numbers by profess
sional talent,
Another innovation this year will be
a ward where the Mitchell owners
with young families can leave their
children This ward will be in charge
of several competent nurses, who will
look after their charges while the
mothers and fathers are enjoying the
banquet.
William Mitchell Lewis and his wife
will come to California to take part in
the jubilee. Mrs. Rogers will also be
present.

mo Tire Trouble shawmut car which
ON Long Trip completed comp e,.a II the New lew
finished in that city
with the original air in two of the
tires. This is considered a remark
able performance in view of the sur
face conditions the car had to contend
with in crossing the continent
According to the report of Nelson P.
Lewis of the New York board Of esti-
mate and appor-
Solution Of fbs ds solutions I9ns,e of
Dust Trouble me me, hesd p ided i,,h
ITO three classes.
OF these the most practicable one is to
gradually, with binding materials
which viii make them proof against
the dfsintegrating forces of high
speed Mr.. Lewis says. 1T must be
conceded that grit or stone dust of the
same kind as that OF which the road is
built, or sand or mixtures of loan or
clay, are not suitable for the roads as
binding materials when freely used by
automobiles ONLY a nerf6rt bntnnUA-
nous roadway, of which all the fine
surface materials are protected against
being scattered is able to stand the
passage of the extra rapid vehicles in
use today. Either the roadbed must
be so dense as to be unaffected. or
more yiscous and lasting binding ma
orally believed that some form of
bitumen is best adapted to this pur-
pose" A prepared tar is frequently
selected by the. French. English and
American road builders for reinforcing
the binder of macadam roads. 1t is
recognized that the dust should be
kept from forming if possible. In the
United States substance known as
tarvia is obtainable in three forms.
One is very thick or dense, sufficiently
STICKY to act as binder, and is used
in the construction of new highways
where the stone is large and the spaces
large to be bound; a lighter prepare
ton is used where the surface is more
compact, and a still lighter, for use
on Ola ROADS, Wnere there Is to be no
resurfacing. The tarvia acts as a soft
cement between the stone, and the
particles of dirt, but unlike cement
is concrete, does not become brittle
and remains resilient and waterproof
Experiments seem TO show that
when the surfaces of roads have
been tarviated thay do not break
up but become rolled down and
smoothed out, and consequently do not
grind off any dust. At the same time
dust which is blown on the road adj
heres to it and is rolled into the mix
ture, and does not rise again 1t is
claimed that roads thus tarviated have
remained dustless for at least a season
upon one application of the sub
stance.
