The n!ost imperfect science is mete-
orology The margin of error In Its
calculations is sometimes enormous
sufficient To completely reverse pre-
diction.
The weather bureau is a useful in
stitutiol,, ba'ed upon an incomplete
system Of correlated facts of observa-
ton. which are scientific as far as they
go. But there are elements concerned
in the production of weather about
which the methods of meteorology
give no information.
There are birds. insects and four
footed animals which have an incom-
parably greater foreknowledge of
weather charges than the entire scien-
tiic corps Of the agricultural depart
lnent possesses.
When the Projectors of the weather
bureau give warning Of an approach
ing storm they act on very much the
same principle as that on which a rail-
road time table is based. A train hav-
ing been announced by telegraph as
started on Il given line will arrive in
regular succession at certain points
along that line and a station agent at
any given point can, if no accident in
tervenes, foretell the moment Of the
trains arrival at his station.
Storm centers. or cyclones. moving
across the country are in some ways
comparable to trains following a time
schedule. But unfortunately they do
not run on rails, they are not driven by
an invariable force, they are subject to
interruptions and obstacles of many
kinds, and instead Of always keeping
the track and following the course
they frequently wander vaguely about
or take an unexpected turn or else
fade away like exhausted whirls in wa.
ter.
In fact. the weather bureau predic-
tors are in the same quandary in which
train dispatchers would find themselves

continually drifting this way and that.
getting crossed and entangled or sink
ing into suddenly formed quagmires
and thus disappearing for good.
Meteorology as science of weather
prediction fails just because it pos
sesses too few facts. With the aid Of
the telegraph the weather bureau can
If lucky follow the trail Of q storm
center across the United States. but It
cannot tell just how a new storm Is
born nor just when or where It will
begin it's course
The one only great fact on which 1t
bases its whole system of prediction is
the general tendency of cyclonic dis
turbances in this country to travel east.
ward with a northerly trend, while
storms originating around the gulf Of
Mexico and the Caribbean sea usually
come up the coast.
But the official weather prognostica.
tors are as much in the dark as the Or
binary citizen concerning what Is going
to happen in the atmosphere next week,
and they really know nothing about
any storm until after 1t has begun its
career, and then all that they know Is
the course tnat it wifi ttakie-in case-it-
doesn't happen to change its mind.
A slight variation in the intensity, or
quality, of the radiation received from
the sun might account for sudden
changes or abnormal, weather, and re-
cent investigations show that such va
riations occur, but what is needed Is
more accurate knowledge about them
and their effects. Heat and light are
only two of an infinite number Of
forms of vibration sent to us from the
sun. Everybody knows that when the
weather records show that two days
are precisely alike In temperature, In
humidity. etc, human nerves prove
that~they are vastly unlike in some IN
named popularity which affects the
springs of life.
The spider busily and confidently
spinning her webs in preparation for
spell of fine weather which some un-
erring mechanism of foreknowledge
within her enables her to detect Is q
surer guide than a barometer. She re-
spends to vibrations as yet only guess
ed at by science. and so perhaps do the
supersensitiye nerves of many human
creatures.-Garrett p. Serviss in New
York Journal.
