190 REPORT OF THE CALIFORNIA EARTHQUAKE COMMISSION. 
In the southwest room the same spy-glass was upset toward the northeast, and from the top 
of the tall bookcase, from which had before been thrown the china vase, a bronze figure a 
foot high was precipitated to the southwest. In the hall, on a bookcase facing west, a 
small wooden clock was tipt over to the east against the wall. At 9 o’clock that evening 
there was another shock almost as heavy as the first one, but by that time I was too rattled 
to take much note of it, especially as I had not started the clocks up again. But the next 
morning I went at them, and found that in some cases the pendulum had been swung out of the 
wire loop from the escapement. I tried to locate the direction of the quake from the condi- 
tion of the clocks, but found that they had stopt indiscriminately, without regard to length 
of pendulum or direction. They have pendulums ranging from a few inches long to several 
feet. No plaster was cracked in the house, but many pictures were out of line, and the 
quakes of May 6 broke off two of my chimney tops at the roof line, the southwest corners of 
both being moved about 0.75 of an inch in that direction. 
In the Rossi-Forel scale, I placed the shock of April 18 in class VIII and those of May 6 in 
class VII. In none of the shocks was any disturbance noticed on the waters of the lake, nor 
was there evidence of there having been any waves, yet on the 18th a plank connecting 
my floating boat-house with the bank was found with its outer end in the water, showing that 
the boat-house had been pulled away from it. This plank ran about east and west. In all 
of the shocks the house seemed simply to sway backwards and forwards. There appeared 
to be no up and down movement. In the cellar under the house the milk was thrown from 
the pans in a northeast and southwest direction. 
Bartlett Springs (Mrs. M. E. Clark). — My husband past the night of April 17 at Upper 
Lake, where the shock was quite severe, but my son, a boy 16 years of age, was on the 
ranch, 5 miles northwest of Bartlett Springs. The shock was severe enough to stop the 
clock. He and another boy felt the prolonged tremor and the rocking of the house. 
They were dressing when the shock occurred. Nothing, however, was reported as hav- 
ing been knocked over, nor was any milk spilt from pans. At our nearest neighbor’s, 
4 miles northwest of our ranch, nothing was known of the earthquake till it was men- 
tioned to them 3 days after the event, altho a member of the family thought he felt some- 
thing. At another neighbor’s, 5 miles northwest of here, at Horse Mountain, the wife 
was awakened but not the husband. At Twin Valleys Ranch, a smart shock was felt 
and the clock was stopt. 
Lower Lake (W. C. Goldsmith). — No chimneys were thrown down in the town, but 
2 chimney tops fell to the southwest at a point about one mile northeast of the town. 
Mr. Weaver reports that Lower Lake is on Eocene sandstone, and that the shock was much 
less than at Lakeport or Upper Lake. 
Sanhedrin, Lake County (V. L. Frasier). — This place is in a small alluviated valley 
surrounded by mountains. One shock was felt which was not severe enough to throw 
chimneys. The motion was from northwest to southeast. Some men in a tunnel in 
solid rock, 800 feet below the surface, did not feel the shock, and people living on the sur- 
rounding mountains report the shock as much lighter than in the valley. 
In the district about Knoxville, Mr. Weaver reports that a few chimneys at ranch houses 
fell, but that no severe damage was occasioned. To the east of the crest of the Coast 
Ranges, in the latitude thus far considered, observations indicative of the intensity of 
the shock become more scattering, and people generally attached little importance to 
their experiences of the morning of April 18. 
FORT ROSS TO BODEGA HEAD. 
We return now to the coast south of Fort Ross. An examination of the coast between 
Fort Ross and Bodega Head was made by Prof. J. N. LeConte and Mr. A. C. Wright. 
The portion of their report dealing with the distribution of intensity follows: 
From Fort Ross the line of the earthquake fissure was followed south to the point where 
it passes into the sea. From this point we followed the beach for 8 miles. Several slides 
were seen about 3 miles south of the Fort. One of these was of great size, being between
