To the Editor OF The EVENING STAR:
In the line OF medicine 1t Is the positive cases
that Interesting" particularly as .'clinic"
DO they rix the attention OF the young student,
when perhaps the more ordinary cases excite no
particular attention specially serve to illustrate
the treatment OF disease.
So TIE positive cases In meteorology, such as the
"heated terIns," the "cold waves" and heavy
storms Of lain or snow serve to center the atten-
ton From August TO 81 we had a particularly
hoI and 'cIose" spell. on the afternoon OF the sth
we had a severe 'local' which gave little
temporary relief, but the real relief did
hot come Till the 10th. Why was this? Glance at
the weather map, and see, not only the cause
from day 10 day and keep the run" OF the move
Inent OF the atmosphere, and you will not only be-
laws in this department, but have tue benefit OF
the practical Information gained in that way.
Does IL pay 10 be able TO read the map?
Most asSuredly. The map ha already become O
great Institution; one that all Intelligent persons
should heed
Slows" forever chase one mother around the
world, ever ON general lines from the west toward
the east. IL their speed, direction and intensity
were regular IL would ouly be matter OF simple
arithmetic 10 calculate the weather from day 10
day, hour 10 hour. Bus while In nature
there Is general plan, always the same,
rlety Is great and never twice alike. MeteoYoIogy
can never be what may be termed an "exact
science, but IL Is none the less important for that
In nature there Is very little that can absolutely
come under the ''eXact science" head. The me-
te0rolOgist must get 10 be expert In guess
ny-all that the word guess implies
When the line OF thirty (Darometer) has
touched the PACING coast, on the
NTH day thereafter the advanced lines OF IL Will
generally reach the line OF Washington While
this may be taken as iair average II must not be
depen1ed upon, Tor the "hgh" that reached this
Washington line on the 10Th would on the five
days schedule, have been here the TIN, for then
IL Was due; but we see that II was three
days later than the average. Why this delay?
Why, any varieJyin nature?
There Is always struggle and compromise, In
this nature teaches Ls a good lesson. We may
attempt 10 do certain things, but there are always
many forces 10 contend against. some OF them we
can calculate and SONS we cannot. We must
abide The tiIse and the result or the conflict SO
with these highs and slows" as they travel
across the country. The Inequality or variety OF
the eaTth's surface Is the cause OF the variety In
these factors, as has already been discussed In
these papers From August 3 to we were under
the influence or north slow" north @iow''

north. The greater the number OF slows, follow.

be- Relief can only come in two ways: by .shtphD
or by a south SLOW" one moving on a relatively
south line whereby north winds are engendered
During the summer months, frequently about
the middle OF August, we have slow" from the
