The San Francisco Bicycle Protective
Association met last Thursday morning,
Cal Ewing in the chair. Robert w. Dem
mis- secretary. The principal subjects dis
cussed at the meeting were good roads
and streets, the lighting of Golden Gate
Park by electricity and the construction OF
bridges for crossing frehose without en-
dangering the lives of riders. The execu-
tive committee was instructed to cooper
ate with the newly organized Cycle Board
OF Trade in the matter of street improve
ment, etc.
The Liberty Cycling Club has elected the
following officers: George w. Payton,
president; A. c. Gherini, secretary-treas-
urer; William Beattie, captain Fred
ond lieutenant; o. ST. Denis. sergeant-at-
arms; DR.. Frank Ihrall, surgeon. To-
morrow the club will have run to the
Cliff House. The Libertys will not enter a
team in the coming relay race.
Thomas s. Hall of the Bay City Wheel
men has been familiar figure on the
path for the past two years and is consid-
to himself and his club at the recent in
door tournament, and will be given po-
sit1on on the clubs relay team this year
as usual.
1t is erroneous to believe that bicycle
riding should be avoided in every case of
heart disease. Physicians who have made
study of this question declare that it
ha n,o al rt,;,,
stances in which the action OF the heart is
feeble and in which signs Of fatty degen-
Grafton are found. Increased muscular
exercise almost invariably improves the
condition of the muscle aud of no muscle
more than the heart itself. There are.
however, several indulgences that persons
with weak hearts should beware of, such
as straiping to climb hills and meeting
head winds, excessive fatigue and particu-
larly exciting the heart and calling upon
its reserve strength by the use of alco-
hollc stimulants and improper food.
The manufacture of the modern bicycle
prese nts one of the most complex and deli
cate problems IN mechanical engineering
"a problem more difficult of solution than
the construction OF bridge, a locomotive
or twenty story building. The reason is
that what scientists call the ''factor of
safety" is lower in the bicycle than in al
most any other mechanical product. In
high pressure guns, for instance, the factor
OF safety is even as great as twenty, whic n
means that the guns are made twenty
times as strong as is theoretically neces-
sary for the strain they must bear. In
ordinary guns the factor OF safety is twelve,
in boilers it is about SIX in bridges usually
hve and Ill almost every cons siruction of
machines it is at least four. These wide
margins OF extra strength are considered
necessary as an offset to errors in theoreti-
cal computations or defect in construction
or material. With the lightness of con-
struction in bicycles this is reduced to a
very small margin, being as low in some
instances as 1.25. This being SO, one can
readily understand why the makers of
standard machines maintain such rigid
system of inspection.
The Pacific Cycling Club celebrated its
second anniversary last Tuesday evening
by giving theater party at the Columbia,
after which the members enjoyed a ban
