ISOSEISMALS: DISTRIBUTION OF APPARENT INTENSITY. 279 
about 30 miles an hour, a short distance south of the bridge over the Pajaro. About 
10 cars in the middle of the train were thrown off on both sides of the track. The 
track at the southern end of the Pajaro bridge sank from 2 to 4 feet for a distance of 
150 yards, and between Chittenden and the bridge the track was bent in an S-shaped 
curve in several places. The concrete piers of the bridge were cracked, and the granite 
cappings shifted as before noticed. (See plate 658 and fig. 43.) There is much sulfur, 
oil, gas, and water in the hills here. A marked increase was noted in the flow of oil 
and water, and more gas and sulfur became associated with them. It is said that since 
the earthquake 16 years ago small shocks have been felt each spring, often severe enough 
to crack chimneys, and a deep well becomes muddy 2 or 3 days before these occur.

Fie. 58.— Displacement of buildings at Chittenden. 
Fifty-two distinct shocks were felt during the day of April 18, and 32 that night. 
From 1 to 4 shocks were felt every day thereafter up to May 16, and from 2 to 5 
occurred every night. Two miles north of San Juan, Mr. Canfield’s house, at the foot 
of the hills 0.5 mile east of the fault, was moved bodily 2 inches westward, and the 
chimneys were completely thrown down; but a house 150 yards west of the fault, altho 
considerably shaken, appears to show the shock to have been less severe on that. side. 
San Juan (G. A. Waring). — The town largely escaped by virtue of being on solid 
ground. A large inner wall at the San Juan Mission fell, but it was no doubt weak, as 
other parts of the building appear unhurt. Only one or two chimneys in this village 
fell, but in the bottom-land between San Juan and Hollister the condition of the houses 
indicates a heavier shock on the low ground. 
SANTA CLARA VALLEY. 
Information regarding the distribution of intensity in Santa Clara Valley has been 
contributed by a number of observers whose names are given with the paragraphs deal- 
ing with the respective localities reported upon by them. 
Newark (¥. EK. Matthes).— Nearly all brick and tile chimneys in the village were 
broken off; the direction of throw varied. Plaster cracked and fell in quantities on 
the lower floors of hotels and several other buildings. There are no brick houses in the 
town; and most of the frame dwellings showed no effects of the shock, At the depot the
