ISOSEISMALS: DISTRIBUTION OF APPARENT INTENSITY. 165 
Big Bar, Trinity County (W. A. Pattison). — Mr. Pattison was in bed in a very strong 
block-house, which shook and made a crackling noise. His pendulum clock stopt. 
Nothing was overthrown. There was a tremor, then a stronger shock. The movement 
seemed to be from northwest to southeast. 
Papoose, Trinity County (C. Blackmore). — An electric light bulb hanging by a cord 
about 4 feet long was swung in an are of about 22 inches. 
Alturas, Modoc County. Population 500. (C. B. Towle.) — The hanging lamps in a 
saloon were found at 5° 20™ a. m. to be swinging east and west. A tub leaning against 
the house on the porch was thrown down. Some men camped near the town felt a trem- 
ble of the earth. Others in camp several miles from the town were up and heard the low 
sound of the earthquake, but did not feel the shock. 
Susanville, Lassen County (James Branham).— Mr. Branham was in bed with his 
head to the north and felt himself roll back and forth in the bed, from which he con- 
cludes that the motion was east and west. The shock was, however, not severe enough 
to be generally felt by people asleep. 
McArthur, Shasta County. —'Two shocks were felt, the first the stronger, the motion 
being east and west. Nothing was overthrown, according to a report by John McArthur. 
Stella, Shasta County (J. F. Schilling). — A pendulum clock in the Woodward Hotel 
stopt. 
Redding, Shasta County (L. F. Bassett). — Mr. Bassett was indoors, squatted on his 
toes in front of a stove lighting the fire when the shock came. He felt no tremulous 
motion and only one principal disturbance, which lasted several seconds. There was a 
slight swaying motion of the house for perhaps 10 seconds, and this was strongest at the 
beginning. The motion tended to throw one toward the north. No objects were over- 
turned, but the windows rattled a little. A rumbling noise preceded and followed the 
shock, which he ascribed at the time to a passing train; but there was no train due at 
that time. 
(B. Macomber.) — The shock was not intense enough at Redding to move loose objects. 
In a few cases clocks were stopt. The shock was felt violently and many people were 
awakened by it. It was preceded at a very slight interval by aroar. Up to the moment 
that the most violent part of the shock struck the house, I was under the impression that 
the sound and the vibration were both caused by a train passing. The direction seemed 
to be from slightly west of north to slightly east of south. 
Cottonwood, Shasta County (J. B. Heiderick). — A clock stopt. 
HUMBOLDT COUNTY. 
Arcata, Humboldt County. Population 950.— A.S. Eakle reports that a few chim- 
neys were damaged. Mrs. William Nixon reports that a fissure opened in one of the 
streets of Arcata, into which her informant, a reliable man, said he could insert his 
hand; but by night it had closed again. She was also informed that a brick from a 
chimney was thrown 40 feet toward the south. The main shock appeared to her to be 
east and west; two rocking chairs in different rooms, both facing east, were observed by 
the separate occupants to rock violently. A clock on a north wall did not stop, while 
many on east or west walls did. Of two clocks on the south walls of the same house, 
one stopt while the other did not. Mrs. Nixon places the intensity in Arcata at VIIT on 
the Rossi-Forel scale. She reports further that Blue Lake felt the shock to the same 
degree as Arcata, with falling chimneys, etc., and that shocks were felt up Mad River at 
Angel’s Ranch and on Redwood Creek at the Berry Ranch. A later shock was felt at 
15 10™ a.m., which stopt a clock on a north wall. 
Eureka, Humboldt County. Population 7,350. (A. 8. Eakle.)— Eureka was damaged 
to the extent of about $5,000, according to report. Most of the signs of destruction had 
been repaired, but a walk thru the town convinced me that the intensity of the shock
