A THIRTY-MILE RECORD.
LONDON, August 3.
A 60-horsepower Napier motor car won
the 30-mile race on the Brooklands track
on Saturday at a speed of 101 miles an
hour. A new record was created. A Mer-
cedes car of 75 horsepower was beaten by
only 60 yards. Although the speed of the
Napier car is a record for 30 miles, it is
not the highest yet produced, Nazzarro, the
“Demon motorist,” having on June 8 on the
same track covered three miles at 111 miles
an hour. At times he travelled much
faster. On other tracks even greater speeds
have been attained.
To judge from the speed of 121.6 miles an
hour, reached by Mr. A. Lee Guinness dur-
ing the recent, motor car trials on Salt-
burn Sands, this course is little Iess speedy
than the world-famous beach track on the
east coast of Florida, on which so many
sensational speed feats have been per-
formed. It was on this course, which
runs for 100 miles by the side of the sea
and is almost as hard and smooth as a
billiard table, that Mr. W. K. Vanderbilt.
jun., covered, in January, 1904, a rale in
39 sec. (over 92 miles an hour). Since
this feat, which was considered phenomenal
at the time, records have had a bad time
in Florida. A year later, on January 30,
1905, Mr. Arthur Macdonald travelled a
mile in 34 2-5 sec., more than 104 miles
an hour. In the following January Mr.
Stanley, on a steam car, brought the time
down to 31 4-5 sec.; and three days later,
a speed of two miles a minute was exceeded
for the first time, when Mr. Marriott, on
a Darracq car, placed the record at the
starting figure 28 1-5 sec., representing a
speed of 127 2-3 miles an hour.
