.ISOSEISMALS: DISTRIBUTION OF APPARENT INTENSITY. 217 
Esparto. Population 200. — Clocks were stopt. 
Capay, Yolo County. Population 200. (E.S. Larsen.) — Sleepers were awakened and 
milk slopt over in pans, but no chimneys were thrown, no windows were broken, and no 
clocks were reported stopt. 
(S. Schwak.) — There was one continuous shake from northeast to southwest, resulting 
in the spilling of milk from pans. No objects were overthrown. 
Guinda, Yolo County (J. Jacobsen). — There was one continuous shake for about 25 
seconds, the apparent movement being from northwest to southeast. A vertical upward 
motion was also experienced. Nothing was overthrown. 
Rumsey, Yolo County (J. M. Morrin). — The movement was from southeast to north- 
west. There were 2 maxima, the second being the stronger. 
(EK. 8. Larsen.)— There was no damage whatever to buildings, but most sleepers were 
awakened. The vibrations were long and gentle. 
Woodland (EK. 8. Larsen). — Most sleepers were awakened, but no chimneys were 
thrown and no glass was broken. <A few clocks were stopt, one of which faced east. All 
agree that the vibrations were slow and gentle and of a rocking nature. Mr. J. L. Spohn 
states that he was awake at the time, and observed an electric-light globe hung by a cord. 
At first the globe vibrated east and west, and then had a rotary motion. 
Davisville (E. 8. Larsen). — Most sleepers were awakened. One man reports 2 or 
3 chimneys cracked, but every one else denies this. Some plaster was cracked and doors 
were jammed so that they required resetting. No glass was broken. Various observers 
report vibrations from east to west or north to south, but they do not agree. All report 
the vibrations long and slow. 
Maine Prairie, Solano County (Mrs. A. Rattike). —No damage resulted from the 
earthquake. A gentle swing was experienced, the motion of which was from southwest 
to northeast, as evidenced by waves generated on the surface of the water on the over- 
flowed land. 
Rio Vista, Solano County. Population 682. (J.C. Stanton, C.K.) — The character 
and effects of the shock are described in a note published in the sgt Sh Sutin Report 
of the U. 8. Weather Bureau for April, 1907, as follows: 
The shake was very severe. It commenced with a number of quite long vibrations from 
northwest to southeast and wound up with the figure 8 motion which often accompanies 
seismic disturbances. It was quite difficult for persons to maintain their footing; but 
strange to say, nothing was thrown down or overturned, which may be attributed to the 
gyrating motion. The duration was about 30 seconds, and I am convinced that had it 
continued 30 seconds longer hardly a house would have been left standing in town. Some 
lumber piles were thrown down in a lumber yard situated upon a pile wharf, where the dis- 
turbance seemed worse than anywhere else; and the water-tower, 60 feet in height, consist- 
ing of 2 large tanks containing 100,000 gallons, was seen to.sway violently. 
Collinsville, Solano County. Population 300. (Joseph Antonini.) —Collinsville is on the 
peat of the tule land, with hard clay 2 feet below the surface. The largest building in 
town, a hotel built on piles, was totally wrecked. Chimneys and water-tanks were over- 
thrown. The movement was east. 
NORTHERN SIERRA NEVADA. 
Butte County. — At John Adams, population 75, and at Berdan, a slight trembling of 
the earth is reported. At Paradise, population 100, Mr. F. W. Day reports that hanging 
objects vibrated violently, and that a “sinking sensation’? was experienced. At Stan- 
wood the shock, according to Mr. 8. E. Rowe, was very slight and noticed by very few 
people. At Honcut, population 100, a slight shock is reported by Mr. D. B. Robb. 
Quincy, Plumas County. Population 516. (L. A. Barrett.) — The shock was heavy 
enough to awaken a few people, but was not felt by the majority of the inhabitants. Mr.
