SACRAMENTO, Cal, June 4.-The
preliminary report of the state Earth
quake Investigating commission was re-
celved yesterday at the office of Governor
Pardee. Under the heading of the results
the report says.
One OF the remarkable features Of the
coast ranges of California is a line Of
peculiar geomorphic construction which ex-
tends obliquely across the entire width of
county 10 Riverside county. The surface
feature along this line has been formed
by dislocation of the earth's crust. or a
series of dislocations in times past with a
differential movement of the parts on
either side of the plane Of rupture.
The movements that produced the line
are attributed to separate earthquakes, ex-
tending back into the quarternary period.
In general terms, the causes of these
movements are attributed to the theory
that stresses are generated in the earth's
crust and accumulate until they exceed the
strength of the rocks composing the crust
and find relief in sudden rupture. The
earthquake of April is is said to have been
due to one OF these movements and the
extent of the rift is described as extending
from the vicinity of Point Arena to the
neighborhood Of San Juan, Benito county.
a distance of 1856 miles
The evidence of the rupture and of the
dfferential movement is clearly defined in
a continuous furrow in the surface soil
several feet wide. The average horizontal
displacement is twenty feet wide.

Heavy Rains Coast.
SAN FRANCISCO, June A heavy rain,
accompanied by high winds prevailed here
yesterday, and almost unprecedented
weather prevailed throughout the northern
portion of the state. 1t is twenty-five

bureau, since similar conditions were ex-
perienced a. this time of the year. Lo-
cally, the rainfall yesterday was 30 of an

20.37 inches.
Comparatively little suffering was caused
by the rain throughout the refugee camps.

downpour and were in some measure pre-
pared for It.
