SAN FRANCISCO, Cal, Aug. lst, 1891. J
The month of July has been dis
tnguished by excessively high tempers.
tures, local storms, high winds and early
rains. All cyclonic disturbances, that is
their centers, have moved eastward over
British Co,umbis, beyond the limits OF
the Weather Bureau Charts. 10 two in
stances the cen.ers came sufficiently far
south to give rise to light rains 10 North
ern Callfornis. These distur Dances passed
over British Columbia on the 7th and 9th,
and on the 24,h and 25th. This last die
turbance moved eastward with extreme
slowness, remaining 10 the vicinity OF the
Pacific Coast States from the 20th TO the
Both. 1t essterly movement was delayed
by the presence of very decided area Of
high barometric pressure. central in the
vicinity Of Montana for several day. This
high pressure are gave rise to the hot
wave in Oregon and Washington on the
22od and 23rd, and as it moved further
southwark it developed the hot wave in
Southern California on the 24th and 25th.
This snti-cyclonic area was of enormous
extent, embracing the whole country
from the Great Lakes to the Rocky
Mountains and from British America to
Mexico. The high temperatures hasten
the ripening OF crops 10 many cases but in
parts of California injury was caused to
the fruits. There was some injury TO gar
den crops in Oregon. The early rain
caused considerable surprise to farmers
and fruit growers 10 Northern California
aud some injury was reported to grain
and fruit crops, also TO hay that was cut
aud was laying in the fields. As, gen
orally speaking. little preparation is made
by the farmer aud hortieulturist in Cali
iornis, during the Summer season, to
guard against damage by inclement
weather, the loss sustained by them dur
ing July has apparently not been severe
under ths circumstances. 1t may be a
question IS to whether greater precaution
would justify the expense Of providing is.

cidedly above the average in Eastern and
Southern Oregon, and considerable sboveiu
