Tho syHtom Of
WEATHER SIGNALS,
established By tho Federal Government two
years ago last November, has thus fur proved an
almost unqualified Brccosa. beginning with IN
stor1n warnings, it has now reached IN averago
nf fully 8O per cont. That ia, four out of.oye-
~ five Of tho storm warnings ore verified
by tho arrival Of storm within live or six hours
that tho Bureau hns extended the list OF sta
kionH greatly since tho commencement, tho
number being now really double that repre-
eented by tho average daily reports received.
.9'ho Bureau now proposes to make IN impor-
&a1lt extension Of its system Of storm warnings
III the noighborhood OF Chicago, if the cooper
alton Of tho city authorities can be obtained.
st il propoBod to oxtend the signals not only in
for tho benefit Of cartainB of .yesaols OH the
lake. In ordor to do this it would DO necessary
to lay n cahlo from tho shore to tho crib, by
which orders could bo convey to tho keoper
signala to DO aoen from groat distance. There
in no doubt that it would bo much better In evory
asay to lay that cablo inside the now tunnel than
to expose it to the dangora incident to position

ing how much thoy arc willing to recommend tho
city should do in tho matter. The Bureau docs
not think it its duty to recommend to tho Govern
ment tho assumption Of the cost otlayng tho cable
botweon tue shore mud tho crib, but would prob
ably be willing to undertake tho expenao Of
transmitting signals if tho cablo was laid by
others. There Gun scarcely be any question OF
tho advisability Of tho undertaking. Tho adj
Eautage to cur nnrino would be almost incalcu-
liable. Il is we'll known tint the greatest danger
