170 REPORT OF THE CALIFORNIA EARTHQUAKE COMMISSION. 
Drug stores suffered most in this respect, and bottles fell principally from the west side. 
Over half the chimneys in the town were thrown down. Several houses moved from 
1 to 3 inches off their foundations. The river water swashed up on the banks. Fortuna 
is partly on the river bottom and partly on the hill slopes above, the Eel River being to 
the west of the town. 
Pepperwood, Humboldt County (J. F. Helms). — In the stores and saloons 10 per cent 
of the property was destroyed by breakage, but on the farms of the neighborhood the 
damage was mostly confined to the throw of chimneys. 
Briceland, Humboldt County. Population 150. (J. W. Bowden.) —The village suffered 
damage to the extent of $1,500 due to the breaking of chimneys, water and gas pipes, 
household furniture, ete. The village is on sloping ground on the creek bottom, the 
latter being in solid sandstone and shale, with the bedrock near the surface generally. 
One 2-story building 30x 80 feet, standing east and west on a concrete foundation, 
was moved north 3 inches on the west end and south 5 inches on the east end. 
On the east bank of the main Eel River, to the east of Laytonville (A. S. Eakle), the 
ground was cracked for a distance of 300 yards, the trend of the crack following the 
course of the river. The crack was merely local in the alluvial bank of the stream, per- 
haps 100 yards from the water. A long bridge crossing the stream at this place showed 
no effects of the shock and the few houses in the vicinity were not damaged in the least. 
Further east, at Covelo, the shock was not violent. 
Thorn. — Dishes were shaken from shelves in houses. 
NORTHERN MENDOCINO COUNTY 
By E. S. Larsen. 
In the territory from Laytonville to Covelo, and northerly to the boundary of Trinity 
and Mendocino Counties, the shock was sufficiently severe to awaken nearly all sleepers, 
to throw milk from pans, and to jar a few things from shelves, but not severe enough to 
do any damage to buildings. No chimney was reported as damaged. Most of the chim- 
neys are of rough stone, tho a few are of brick. Some plate glass was broken in one of 
the stores at Covelo, but the building was in course of construction and the windows 
were temporarily and insecurely put in place. <A large proportion of the residents claim 
to have heard a roar just preceding the earthquake shock, and several report the shock 
as beginning with a slow east and west motion, and ending with quick severe jerks. A 
man riding in the hills at the time did not notice the shock, but his horse stumbled 
repeatedly without apparent cause. 
There were a great many earth cracks formed in the Round Valley region. “Some were 
examined, but many had been obscured by the winter rains, while others were not visited 
on account of the heavy rain which set in and made it impossible to cross the streams or 
get about in the hills. About 20 miles north of Covelo, about section 2, township 24 N. 
range 14 W., on the Horse Ranch, and about 700 feet above the north fork of the Kel 
River, is a crack about 40 feet across and 600 feet long. At the southeast end a ridge of 
massive sandstone makes that part of the terrace somewhat wider. At either end are 
small gullies. At the back, to the northeast, a rather steep hill of sandstone rises abruptly 
from the terrace. Below, to the southwest, the terrace ends in a steep slope which shows 
evidence of repeated sliding and has several springs near its base. There are no trees 
on this slope, but the hill back of the terrace is covered with trees and there are some 
trees on the terrace, mostly on the hill side of the crack, altho several oaks 8 inches in 
diameter are on the side toward the river. The main crack is about 400 feet long. It 
is indistinct and disconnected at the northwest end, but gradually becomes mere 
prominent till it reaches a point just beyond the center where the river, or southwest side, 
is 6 inches higher than the hillside, and there is an open gap of about 8 inches, It then
