210 REPORT OF THE CALIFORNIA EARTHQUAKE COMMISSION. 
turned on their bases from a few degrees to 20° counterclockwise; 2 were down and 
2 had the top ornaments thrown off. At the Catholic Cemetery, out of 6 tombstones of 
the above type 1 stone was turned clockwise and 1 counterclockwise. This ceme- 
tery is in the valley. The Valley Cemetery has 2 tombstones out of 6, of the above type, - 
turned counterclockwise. The Sonoma Valley High School had 3 chimneys out of 6 
turned counterclockwise; the other 3 fell. I found chimneys on 3 other houses turned 
counterclockwise, and 1 chimney turned clockwise. Two miles south of Sonoma, at 
Mrs. William Clemens’, all 3 chimneys were turned counterclockwise. Mr. T. A. Lewis, 
physies teacher at the High School, described the shock as being at first a temblor, 
vibrating northeast and southwest, then a short calm, and finally a longer and harder 
twisting shake. Dr. Grey, of the State Home at Eldridge, and several others, gave a 
similar description. 
Shellville. — About three-fourths of the chimneys were thrown or twisted. 
NAPA VALLEY TO THE SACRAMENTO VALLEY. 
Napa Valley (C. E. Weaver). — At Calistoga, population 700, a large number of chim- 
neys fell and 2 brick buildings were thrown down. Clock stopt. <A few local slides on the 
south side of Mount St. Helena were confined to the alluvium. At the town of St. Helena, 
population 1,600, a stone building of the California Winery Association was slightly 
damaged, and 8 brick chimneys in the town were overthrown. At the Veterans’ Home, 
at Yountville, the buildings constructed of brick and stone had two corners thrown down 
and the walls cracked. At Napa many brick buildings were cracked, and walls thrown 
down. Chimneys were generally overthrown. No damage was sustained by the concrete 
buildings, nor by the machinery contained in them, at the cement works at Napa Junction. 
Calistoga, Napa County (Dan Patten). — Nothing was thrown down in the house. 
In the milk-house cream was thrown from full pans on the northeast side. <A large water 
trough near the house had the water thrown out on the northeast side. Some large rock 
was thrown down from cliffs up on the mountain (Mount St. Helena) at an elevation of 
4,000 feet on the northeast side. Mr. Patten was in front of the house, the east side, and 
heard a rushing noise. He had time to look up the road to the south, and then turn and 
look north, expecting to see some fast driving team, before the shock came. He felt 
first a tremor, and then 2 heavy thumps a few seconds apart; then tremors gradually 
decreasing until probably 0.75 minute had elapsed. 
St. Helena, Napa County (F. Blachowski). — At the Sanitarium near St. Helena, 
which is on a hillside with rock near the surface, objects were thrown mostly toward the 
east. Some chimneys were turned counterclockwise, and a twisting motion was felt. 
There were 2 maxima in the shock, the second being the stronger. 
Rutherford, Napa County. — Mr. Joseph Mora was starting out on his bicycle when he 
heard a loud noise like that of a country wagon; he stopt and was then shaken by the 
earth moving violently; the trees swayed wildly. The sound and the shock came from 
the southwest. All the wine-cellars and structures that were not well built were par- 
tially thrown down. Chimneys came down from all buildings. Niebaum’s wine building 
showed no cracks. 
The Veterans’ Home (A. Brown). — The Home is on sloping bench land in the foot- 
hills on the west side of Napa Valley. The chimneys on some of the buildings were 
twisted around, and some tumbled over. Mr. Brown felt his bed rocking north and south 
for about 15 seconds. <A clock stopt. Some plaster fell at the new hospital. Only one 
maximum was observed in the shock. 
Mr. J. M. Clark, of the Veterans’ Home, who maintains a seismograph of his own con- 
struction at that institution, reports that the hardest portion of the shock came, as near 
as he could judge, about 20 seconds after the beginning. There was a rapid increase in 
intensity up to that time; then came the gyratory, upward, jerky motion, which was
