206 REPORT OF THE CALIFORNIA EARTHQUAKE COMMISSION. 
about 1.5 miles south of Windsor is on low, rolling hills. Only 4 monuments out of 35 
to 40 of the class wrecked at Sebastopol and Santa Rosa were thrown down. 
Guerneville. Population 500. (R. 8. Holway.) —In this town all brick buildings were 
badly wrecked. Chimneys generally fell. The Commercial Hotel, a frame building, 
was twisted slightly, contraclockwise. Under the house of Mr. Turner, which is built 
on piles, the piles on the east side were thrown 8 inches east and those on the west side 
4 inches north. Mr. Turner reports the shock as clearly from north to south. His 
workeases were thrown from north to south. The cemetery, which is on a terrace 190 
feet by aneroid above the flood plain on which the town stands, was very slightly affected. 
One monument is reported to have fallen. Three or four show slight shifting. 
SANTA ROSA VALLEY TO SAN FRANCISCO BAY. 
Petaluma. Population 3,900. (R.S. Holway.) — The inspector of chimneys reported 
that the great majority of chimneys fell. (See fig. 64, page 341.) In east Petaluma, on 
the lowland, all but 4 fell. Three brick stores had the entire front thrown out, and 10 or 
more had tops of fire-walls thrown down. The stone hay-barn of McNear was wrecked ; 
also a corner of the stone warehouse. The 2-story brick silk factory had every corner 
wrecked. The central tower and the large brick chimney were thrown down. ‘The ice 
plant near the station had the high brick stack thrown, wrecking part of the building. 
The Golden Eagle, a 4-story brick flour mill, was not damaged; but the 1-story addition 
and a 1-story stone warehouse had portions of their walls fall. There are no authenticated 
reports of cracks in Petaluma nor in the low tidal lands immediately adjoining. Vague 
reports to this effect were not verified. (See plate 73a, c.) 
Lakeville, Sonoma County (C. A. Bodwell). — This place is about 6 miles southeast 
of Petaluma, on a hill slope near the tidal marsh of Petaluma Creek. Chimneys were 
overthrown, plastering badly cracked, and dishes broken. Chimneys and objects were 
thrown to the southeast. There were 2 maxima in the shock, of which the second was 
the stronger. The movement was from southeast to northwest. 
Petaluma northward up Sonoma Mountain (R. 8. Holway). — Northeast about 2 miles 
across the low land, chimneys were thrown down and furniture was moved. No cracks 
were reported in the ground. Thence northward to an elevation of over 1,800 feet, 
nearly all the brick chimneys were down. Houses are usually small 1-story frame 
buildings. Articles were reported thrown from the shelves and furnituremoved. ‘House 
shaken so severely I could not walk across the floor,’ was a common statement. No 
landslides were reported, altho quite a number occurred in this region during the winter. 
Petaluma to Sebastopol (R. 8. Holway). — A drive along this road, which keeps near 
to the western line of Santa Rosa Valley, showed an increasing intensity of shock from 
Petaluma toward the northwest. Chimneys were quite generally down along the entire 
line. At Jur’s ranch, about 2.5 miles northwest, 3 cracks with a very slight dropping of 
small blocks between them, are reported. A temporary flow of water was reported from 
a crack by the road. Small cracks were reported on the road about 4 miles from Peta- 
luma. Near Stony Point school-house, about 9 miles out, 19 cracks across the road were 
reported by the teacher. At Nason’s ranch there is a landslide of the bank of the lagoon: 
100 yards or more in length. Four miles from Sebastopol is another landslide at Davis’ 
ranch, where a house was thrown from its underpinning. Cracks were reported at 
Hansen’s and several places. There is a distinct increase in cracks and landslides in the 
approach to Sebastopol. 
San Rafael, Marin County. Population 3,900. (R.S. Holway.) —“ Half the chimneys 
down” was a frequent report. Most of them were rebuilt at the time of my visit. “A. W. 
Foster’s place, on the hills to the north, had 100 chimneys and only one fell.” A brick
