N@g Bicycle Tips.
It is significant of the large part the
bicycle now plays in the affairs of the
ordinary mortal that nearly every pa
per issued on July devoted more or:
less space to wheeling trips, general
bicycle gossip, or hints and cautions to
the thousands Of enthusiastic wheel
to utilize the next days holiday i'll the
pursuit of their fayorite pastime.
Many of these hints are worth remem-
boring. For instance, one item main
Iains that the testimony of the best
physicians is unanimous in showing
that only a very small proportion of
the wheeling public are adapted by
nature for racing, and many, a young
fellow who is never happy off a track
is but sowing the seeds of a break
down on the verge Of manhood. But
it is not only racing men and century
runners who oyerdo wheeling. Many
a man who has never raced is injuring
himself by humping his back, and pre-
venting the proper expansion of the
chest. This often leads to cardiac
irregularity, poor blood, and a general
weakening of the entire system. Car
diac healthiness, in particular, among
wheelmen, depends greatly on how
they wheel. While moderate cycling
benefits the heart, immoderate cycling
disturbs it. The influence of wheeling
is equally great on the lungs. To in
sure their development, sit reasonably
erect in the saddle, and don't overtax
your powers of breathing. Avoid
drinking anything very cold, unless in
small quantity, taken with delibera-
ton. A good plan is to drink little at
a time and often. To expose ones self
to fresh breeze or to very cold water
while the body is overheated is always
bag. It is bad thing for the business
of the man who runs the repairing
shop at the side of the road, but that
cannot be helped. The bearings of the
best wheel may tighten up, from dust
or grit getting inside, or other causes,
and the wheel will run hard. This oc-
ours oftener, perhaps, to the cones on
the crank axle than elsewhere. The
seat Of the trouble may be detected by
turning the bicycle upside down and
revolving the rear wheel Then notice
where the chain seems to sag, whether
above or below. If below, the trouble
is in the bearings Of the wheel. If it
is tight below and loose above, the
wheel is pulling the cranks around,
and they are harder to revolve than
the wheel. If the adjustment is right
in both places the chain will sag first
on the top side and then on the bottom
in an irregular manner The bracket
bearings receive the hardest treatment
of any part of the wheel, and neces.
sarily require the most attention.
Academy Headache.
A London medical journal discusses
a peculiar variety Of headache, term
ed, not inaptly, academy headache"
to which visitors to the academy and
other picture galleries are subject. 1t
is manifested by strange feeling Of
exhaustion and lassitude, with a de-
sire for rest in the horizontal position
and perfect quiet in the absence of a
strong light. In Investigations on the
occurrence of nsytagmus in persons
whose occupation obliges the eyes to
lie raised above the horizontal line, of
which. curiously enough, miners at
ford the most frequent as well as the
most striking examples, it has been
noticed that the actual development of
the oscillations Of the globe was pre-
coded by stage Of WEAKNESS of the
elevators of the eye. In this modified
form what is usually known as
miners nystagmus" is far more com
mon than is generally supposed.
When, as at the Academy, it is neces-
sary to direct the eyes considerably
above the horizontal line great NUM-
Der Of times, severe strain is thrown
upon the muscles which rotate the eye

or laziness, comparatively few people

leaves the building with the symptoms
above described. 1t is suggested that
those who are responsible for the dis

recognize the fact that the human eye
is not constructed for looking upward
