1t is but natural to respect the theo-
ries Of men placed in government posi-
tIons. In u republic the theory is
that such men become the servants of
the people while the fact is that they
become the peoples masters.
The editor of the Monthly Weather
Review came to the wheathcr bureau
when first organized in 1870 after hav-
ing had long experience with the
Smithsonian Institute IN the same
line. His abilities a,e not questioned
snd he has dominated in the weather
bureau from its inception.
But we should prove all things aud
hold fast only to that which is good.
Because men hold high positions is
not evidence Of their Instability. The
opposite often proves true.
In the Weather Review for Novcm-
Der 1894 the editor of that official tries
to explain the cause Of the transient

What causes these waves? The an

Soaking of himself Prof. Able saws
"ln his preparatory studies the editor
has considered the movements Of the
atmosphere as analogous to the turhu.
lent flow OF "a river ia which ascending
rushes and descending edies alternate
wl,h each other aud where the Press
urcs at the bottom Of the stream must
depend upon the irregularities of the

upon the centrifugal forces within
the edies.
''On surface of such a river at food
stage and superposed upon the edies
that pervadc its depths one may see a
system of surface waves reflected from
shore to shore or a system of standing
waves below any special obstacle.
The atmosphere doubtless presents
such phenomena as these and also
other but similar waves of pressure
depending On heat, on evaporation and
condensed aqueous vapor, or lunar and
solar tides and even on great eruptions
such as Krakatoa."
The waves in a liver caused by the
water running over all obstacle, do not
move with the waters OF the stream
but are stationary as We see where the
waters run over a dam. Over the dam
is a high wave and below the dam is a
low, or the latter is much lower than
the water above the dam.
Bnt these two waves do not move
with the waters while the waves Of
pressure in the atmosphere do move
with the eastward flowing air. Here.
in is the fundamental blunder Of wealth.
or bureau officials and all the thee.
rie' based on it become blunders.
The high wave in . river is made to
represent the high barometer and the
depression in tho rivers surface to
represent The low. The reverse Of
