Mr.. COLLINS READS A PAPER BEFORE THE
FRENCH ASSOCIATION For THz ALvANcE-
MINT or scrrScE
lBY CABLE TO THE HHRALp1.
I. PARIS, August 20, 1873
The members of the meteorological Sec
ton of the Association FRANCHISE for the
Advancement of Science met to-day to hear
Mr. Jerome J. Collins, of the New YoRK
HEnALD weather service, read his paper on
the subject of storm predictions. In this
paper Mr.. Collins dwelt for considerable
length ON the meteorological field of obser-
walton in the United States
PACIFIC COAST INFLUENCES.
His description of the effects OF the noun
tain chains on the Pacific coast on the
course and nature of depressions was very
attentively listened to by the members.
Taking as an example depression APP
preaching the coast from the northwest he
showed how the peculiar alignment of the
axes Of the mountain chains prevented d.
rect obstruction to its eastward progress.
THE CHANGES WROUGHT.
He said cit has often been noticed that
storm areas approach these Pacific coasts as
large depressions, with comparatively low
energy Of rotation around their centres.
But when the area reaches the line of the
coast mountains in Oregon and Washington
Territory it's outline is changed from dis
torted circular to that of an irregular
elliptioal, and the northern end Of the latter
figure is carried toward the coast line more
rapidly than the southern one, causing, as
rule, the first rainfall on the line of first
contact with the land.
cAusss OF IQuAL RAINFALL.
Therefore over Vancouver's Island and
Western Oregon a rapid condensation Of
atmospheric moisture takes place, which so
speedily deprives the air volume imme-
diately affected by the storm of it's HUI
mildly that the lines of equal annual rain
fall ON this section of the coast are very
close together, making q decrease Of pre-
cipitation inland"
TIE ATLANTIC STORMS
In describing another type Of Pacific
storm that arrives on the southern and GEN.
tral section Of the California coast the
reader showedrhow it generally. became d.
vided intos two distinct sub-areas Of low
barometer by the Sierra Nevada range. and
followed the different courses of each until
they reached, the central valley districts.
After givinguminute details Of the move
ments Of the other Pacific disturbances and
also of the Atlantic equatorial storms Mr..
Collins took up the main subject Of the
paper, that of Atlantic storm predictions,
md gave very simple explanation Of the
theory.
>; HIGH WORDS OF PRAISE:
After Mr.. Collins had finished reading
his paper the President, General de Nam
souty, Director tof the Observatory at Pic
du Midi. arose. and made a very compli-
mentary sRefch, declaring, that to. his
knowledge the HEsALD weather predictions
were verified over eighty per cent. He was
followed by Professor Zenger, of the Poly
teohnic School, OF Prague. who announced
himself warmly in favor Of the system.
SAVING LIFE AND PROPERTY.
Able Hougerie congratulated the HERALD
meteorological and said he believed that the
HERALD'A enterprise was the means of saw
ing very large amount of property and of
protecting the lives of many trsversing the
ocean. Before the meeting adjourned the
members of the section returned their
thanks TO the HERALp's meteorologist for the
paper.
