AUTO NEWS OF THE DAY
Prizes Offered for Each Class in
TWenty-four-Hour Race.

AFTER Sil, there VIII be more than one
automobile race at the Brighton Beach
Motordrome on July Is and l6. There will.
IN fact be at least three races, and all
running simultaneously will mako one great
race the like Of which has never before
been seen.
Under the new ruling OF the American
Automobile Association Contest Commit
tee the sanction for the race specifies that
1t shall be held under class c, which has
three subdivisions, according 10 piston dis
placement. In each OF these subdivisions
& special prize viii be given by the Motor
Racing Association for the twenty-four-
hour race at the beach, starting at 9
O'Clock on the evening of July Ii. All the
cars In ali the divisions will be started
together exactly as in single race. There
will be as keen competition to win the di-
vision prizes as there will be to win the
grand prize for the car that travels the
greatest distance in all the divisions.
The decision to hold the division races
practically assures the limit of twelve
starters in the contest There had been
some talk of raising the limit. but after
consultation with the drivers committee
the association has decided that IN the
interest of safety no more than twelve
track at one time It is likely, therefore.
that the entry list will be closed long be-
fore the announced date of July ..
Work of improving the Brighton Beach
course for this race. or series of races, is
now actively under way. The banking of
the corners is TO be slightly increased. and
a new preparation is to be applied to make
the track surface as hard and fast as posi-
bic. These are not the only improvements.
for the Motor Racing Association is having
Its clubhouse. on the track side, repainted
inside and out and made more comfortable
for members. Work also is TO be done on
the grand and field stands. so that the en-
tire plant will be in better shape both for
competitors and spectators than II ever
was before
Entries for all the divisions of the races
should be made with A. B. cordneF at the
city clubhouse of the association. No. 3oi
West 5Sth street. as early as possible to
insure acceptance.
A booklet soon to be issued by the Amer
lean Motor Car Company, of Indianapolis,
contains figures which are interesting as
showing the greater stability of the under
slung type of construction-exclusiv ex-
plotted by the Anlerican-as compared with
the ordinary or oversiung construction.
1t is shown that an American under
slung car will hold the track when driven
at speed of eighty-fouT miles an hour
ever a circle with a radius of 3s7 feet. To
travel at the same rate Of speed without
turning turtle the oveFsIung car must be
put on a circle whose radius is 7SS feet
almost again as much as that required by
tho American.
The reason for this disparity is the loca-
tien of the centres OF gravity in the two
types of construction. In the American ii
is 21.s inches from the ground. and in the
oversIung car So2 inches. II is then shown
by figures that the exertion of centrifugal
force on the higher centre Of gravity is SO
great that the cversluns car will roll over
Il tipped to an angle exceeding 43 degrees,
whereas the Americans tipping point is So
degrees.
