254 REPORT OF THE CALIFORNIA EARTHQUAKE COMMISSION. 
Areas that suffered least were upon rock of some kind in place. 
Towns along the west edge of the Santa Clara Valley, at equal distances from the fault- 
line and upon similar geological formation, showed the same intensity. 
The waters of the bay and of the ocean were quieted by the shock, and there was no 
perceptible tidal wave following the movement. 
The shock was not felt as strongly upon the waters of the bay as upon the land near by. 
There was an unusual flow of water in the creeks draining into the bay near Baden and 
San Bruno, directly after the shock. 
The destruction of buildings and the disturbance of railway roadbeds and rails was 
much more violent thruout the area covered by the incoherent Merced beds than on the 
older hard rock in the adjoining areas. 
There was a large amount of damage done in the cemeteries, which are on zolian sands. 
A large number of the monuments fell at the cemeteries, but there was no consistency 
in the direction of falling to show the direction of motion. 
Motion in more than one direction was suggested by monuments twisted upon their 
bases. Vertical motion was shown in one monument which had the upper portion turned 
upside down. 
NOTES BY OTHER OBSERVERS. 
San Mateo, San Mateo County (Mr. Maxwell). — At the time of the shock Mr. Maxwell 
had led a horse out of the barn to give him water. He first heard a heavy rumble, which 
he took for thunder, coming from the northwest. This was followed by a wavy motion 
of the ground. The earth rose and fell like the swell of the sea, the waves being about 3 
feet high. A water-tank about 30 feet high tipt over to the southeast so as to throw water 
out and allow him to look into the top of the tank, he being 75 or 80 feet distant The 
tank-swayed back to its place without falling. The two wave motions were followed by 
a severe shock, as if the waves from the northwest and southeast met suddenly under 
him. Both he and his horse were thrown off their feet. The horse attempted to run, 
but could not on account of the violent motion of the earth. 
Redwood (K. C. Jones). — The mains of the gas plant are all of steel and suffered no 
damage. The gas-generating apparatus was moved several inches on its foundation, 
and all cast-iron connections were more or less damaged. The buildings, being of frame 
and corrugated iron, were not seriously damaged. A 20,000-foot gas-holder in a redwood 
tank above ground was completely demolished by the earthquake. The shock seems 
to have been particularly severe at Redwood City, and the boiler settings at this station 
were badly damaged, while at San Mateo, 9 miles distant, the settings were uninjured.
