ISOSEISMALS: DISTRIBUTION OF APPARENT INTENSITY. 317 
foundations. The town had no brick structures. The water of the nearby irrigation 
canals had, in places, been thrown up on the banks as much as 6 feet above the usual level. 
Newman. — From Los Banos toward Newman the intensity of the shock appears to 
have decreased. At the latter place, out of 8 brick buildings only one, just constructed, 
was thrown down; one was cracked, while the remaining 6 were undamaged beyond the 
falling of a little plaster. Sixty per cent (36 out of 60) of all the brick chimneys fell, 
altho little other damage was done to frame houses. A man who saw the 53,000-gallon 
railroad water-tank fall stated that at the beginning of the shock it began to sway north 
and south, changing later to east and west, and finally falling toward the west. 
Crow’s Landing. — Out of 18 chimneys only 3, or 162 per cent, fell. Considerable 
water was thrown from the tanks. At a brick oil-pumping station about 4 miles north 
of Crow’s Landing a few cracks were made in the walls. The large oil-tanks and water- 
tanks were undamaged. People in this neighborhood state that the direction of the 
vibrations was first from north to south, changing later to east and west. Opinions differ 
on this point. Many also state that a circular motion was perceptible. 
Grayson and Westley. — The town of Grayson is on the banks of the San J oaquin River. 
No damage was done by the earthquake. A very few things were thrown from the shelves, 
but no chimneys were thrown down. At Westley all the chimneys were found intact. 
One poorly braced railroad water-tank fell, and one remained standing. The people in 
this district maintain that the direction of greatest intensity was north and south. 
From Westley to Mount Hamilton. — From Westley the writer traveled up the Arroyo 
del Puerto over into San Antonio and Santa Isabel Valleys and up to Mount Hamilton. 
There are but few houses on the east side of the summit, and but little data was collected. 
The best was obtained at the Phoenix Quicksilver Mine. Here there are several brick 
buildings and chimneys, but no damage at all was done to them by the earthquake. In 
the tunnel there was no shifting of strata. At Mount Hamilton Observatory a couple of 
chimneys were cracked, but none fell. From Mount Hamilton, the writer went to 
Paicenes, in San Benito County, thru the Panoche Valley to Mendota, thence to Coalinga, 
Dudley, Cholame, and Peachtree. 
Paicenes. — Going from Hollister toward Paicenes the intensity of the earthquake 
rapidly decreased. At the latter place, which is on the gravels deposited by Tres Pinos 
Creek, none of the chimneys (3 in number) were damaged, nor were the clocks stopt. 
Water and milk were thrown from their receptacles in an east and west direction. 
Elkhorn. — At the Elkhorn roadhouse there were 3 clocks; the one facing north was 
undisturbed, while the other 2, one facing south and the other east, stopt. No water 
was thrown from the troughs nor milk from the pans. A few miles northwest of Elk- 
horn, the milk was thrown from pans on the northwest and southeast sides. The infor- 
mation obtained from the residents in regard to the direction of the vibrations was very 
contradictory. 
Emmet Post-office. — At Emmet milk was thrown out in small quantities, but no 
movable objects were moved or upset. Near the summit between Tres Pinos Creek 
and the Panoche Valley, the shock was so slight that people did not think of arising. 
Nothing was thrown over, nor was milk splasht from pans. From Paicenes, where the 
intensity may be rated at about VI, it gradually decreased up Tres Pinos Creek until at 
its source the intensity was about IV. 
Panoche Valley. — This region lies on the east side of the Coast Ranges. At the head 
of the valley the shock was so slight that some of the inhabitants were not awakened. 
On going farther down into the lower ground where the soil is deeper, the intensity was 
slightly greater. At the Panoche store water was thrown from the tank, but no dishes 
were broken. After leaving Panoche Valley, no definite information was obtainable 
before arriving at the Chainey Ranch 14 miles west of Mendota. This ranch is on the
