ISOSEISMALS: DISTRIBUTION OF APPARENT INTENSITY. 297 
the middle 100 feet of its length there is only one floor above the ground-level, and above 
this the structure is open to the roof, without cross-ties or floor-beams. ‘This building 
yielded to the shock in a most remarkable and instructive manner. The whole structure 
was shortened along the line of its longer axis, this shortening being effected by the 
buckling of the walls at the middle or weak portion of the building. Both walls bulged 
toward the west, the east wall in and the west wall out, as shown in plate 117, B. 
Within the building considerable damage was done to the heavy machinery, tanks, etc. 
The ground to the south had been much heaved and otherwise deformed, causing the 
wrecking of trestles, pumping-house, and other structures. The rails of a track at the 
rear of the building were pulled apart, due probably to the slumping of the ground 
toward an old slough of the river. 
In the bottom of this slough water gushed forth at numerous places at the time of the 
earthquake. It is said by those who witnessed the phenomenon that the water spurted 
repeatedly as high as 20 feet, and that the outflow of water lasted for 10 minutes after 
the shock. The places where the water spurted forth are marked by areas of fine, light, 
bluish-gray sand, which is said to be known only at a depth of 80 feet in the various 
well borings of the vicinity. In these areas of fine bluish sand are often funnel-shaped 
depressions or craterlets from which the water issued. 
(S. A. Guiberson, Jr.) —As superintendent of the pipe line, I am in a position to say 
that we have no breaks whatever in any place between Coalinga and the Salinas River, 
and there were no fissures of any kind along the line between these points. This I know 
positively, as I have line riders who were instructed to look closely for any disturbance 
of this nature. The line of fissures seems to have ended north of Priest Valley. The 
conditions prevailing along the Salinas River, and some of the peculiar circumstances 
attending the breaking of our line in about twenty places, are of interest. I was on the 
ground the following day, and only regret that I did not have time to have some of the 
peculiar features photographed. In places our line had been broken and the ends were 
3 feet apart; at the same time the ends of the pipe would be hammered up, showing 
that there had been an opening and closing movement at that point, while at other 
points the line would overlap as much as 4 feet. One of our stations is in this zone of 
disturbance, and the engineers, being on duty, had an excellent opportunity to see what 
most of us who were in bed merely felt. They state that these fissures were opening 
and closing, and that the water and sand would go 20 feet in the air as they closed. 
Southward from Salinas (G. A. Waring). — At points along the railroad liquids were 
generally spilt, furniture was moved, and chimneys cracked. At Chualar, 3 out of 29 
chimneys fell, but 2 were on an old house and were probably weak. At Gonzales the 
intensity seems to have been about the same as at Chualar. Out of 150 chimneys 11 
fell, while many were cracked. East of Gonzales, near the foot-hills, houses were barely 
shaken; while to the west, near the river, water-tanks were thrown down. At Soledad 
3 out of 8 chimneys fell, but the number is probably too small to be taken as a criterion 
of intensity. Some plastering on the first floor of the hotel was slightly cracked, a few 
glasses were thrown from the bar, and some of the bottles were turned around. The 
frame of the railroad tank was so badly twisted that it had to be taken down. A chande- 
lier swung northeast-southwest with a double amplitude of 18 inches. 
At King City, close to the river and on low ground, the intensity was considerably 
higher than at Soledad. Heavy objects, such as a printing-press, slot machines, and 
ice-chests, were shifted a little, and a few things were thrown from-the shelves. One 
low chimney on a low fire-wall fell, but the wall was without a crack. No other chimneys 
were injured. The river-bed sank nearly 6 feet in the vicinity of King City. At San 
Lucas the intensity was considerably lower; milk and water were spilt and shelf goods 
disturbed, but no chimneys fell.
