How isolated we
really are. There was one
stretch this year of twenty-five
or twenty-three days without
a single word from the outside
world. 1t is a marvel the
community does not quarrel
during those fasts. But to
return to and give an instance
of the monotony of man as an
individual. At Paso Robes,
California, where the principal
yard work of the householder
is removing acorns from the
lawn and walks, they have
sulphur and mud springs of
great medicinal powers. Just
like some fellows once describ-
ed the volcano as looking like
hell, a one-lunger at Paso
Robes, in an inspired mo-
ment, remarked as he sat in a
mud bath that he was uncer-
tain as to whether he had after
the experience, more or less
respect for a hog. About 81 of
every 100 persons who visited
the place since that time have
repeated this and half of them
at least have thought they
were springing something real
clever. Around Paso Robes
are the greatest prune orchards
of the world, the best soils for
spuds and same of the best
wheat fields.
Many improvements are
constantly being made to bring
the bicycle as near perfection
as possible. One part has APP.
parently been overlooked, in the
general improvement, and that
is the shape of the sprocket
wheels. 1t is, nevertheless, &
fact, that in nine-tenths of the
bicycles made today, the teeth
on the rear sprocket are made
without correct mechanical
shape; in fact, are mere pro
Ijections to keep the chain from
slipping around the sprocket
without turning the wheel
Some are made in the shap,
of a V, and are so pointed tina
they form a regular incline'
plane, on which the chail
climbs whenever any power i
applied.
The object of the Cycloida
Sprocket as usual ON the Tri
bune is to remove this useless
friction and cause the chain t,
drive as freely as the runnin,
of ball bearings. There is n
necessity for friction in tn
running of a chain; all that i
necessary to prevent it, ar
. four conditions: lst.-Tha
the tooth shall be curved prop
erly to enter the chain withou
contact. 2d.-That the chat
shall pull exactly at a RICH
angle, with its bearing surfac
against the tooth. 3d.-Tha
the chain block shall not shit
or change it's position Will
passing around the sprocket
4th.-That the tooth sha
leave the chain without tn
least resistance. In order
= establish these conditions
has been found, after muc
consideration and practice, tina
it is necessary to form tn
teeth with what is known as
: cycloidal curve, which in mt
. chanics, is the curve by fixe
point, say on the periphery {
circle, when rolled along
Y plane surface. The advantae
is Of the cycloidal tooth is mos
a apparent when the rider
v climbing a hill or forcing h
e wheel rapidly on an up grac
!. or against the wind. This
