ISOSEISMALS: DISTRIBUTION OF APPARENT INTENSITY. 257 
The arcade along the south side of the outer quadrangle that was not directly connected 
with the other buildings was completely wrecked. The arcade in front of the French 
building on the east side and a corresponding piece in front of the Physics building on 
the west side of the outer quadrangle were thrown down. South of the business office, 
parts of the outer arcades fell. This is on the east side of the quadrangle. Parts also fell 
south of the Mineralogy building, on the west side of the outer quadrangle. (Plate 105.) 
The arcades around the memorial court are only partly in direct connection with buildings. 
The free portions appear to have swayed so far out of the vertical that the bottoms of 
the stone columns supporting the arches were chipped off, or cracked at their bases. 
The 2-story woodworking shop of brick, south of the quadrangle, was badly damaged; 
and the forge building, next to it, also of brick and 1-story, was cracked. 
The chemical laboratory, a new stone-faced building (two stories, attic and basement), 
was so badly cracked that most of the walls have to be rebuilt from the foundation. 
The new gymnasium, a stone-faced brick building, was totally wrecked. (Plate 
1048.) It had just been put up, and the inside work was not yet finished. The new 
library, also a stone-faced brick structure, was completely wrecked except a tower of 
steel on which its central dome still stands. (Plate 1044.) This building had just been 
put up, and was not yet finished on the inside when the earthquake occurred. The 
Museum building consisted of an older central portion built of concrete, and extensive 
additions of brick had just been completed. The new brick portions of the building were 
almost all thrown down, but the older concrete part was unhurt. 
The ornamental stone gateway at the entrance to the university grounds, near Palo 
Alto, was thrown down. (Plate 101z.) 
The water-tank at the Faculty Club-house was wrecked and a water-tank in the fields 
east of Alvarado Row was overthrown. ‘The large covered tanks west of the stock farm, 
beside the county road, were not thrown down, but much water was spilt from them. 
Palo Alto (A. F. Rogers). — The most interesting effects of the earthquake in Palo 
Alto were those which showed movement of buildings and those which gave evidence of 
twisting. A number of buildings moved toward the southeast 1 to 6 inches or more. 
Some buildings were left out of plumb and usually they were inclined to the southeast. 
In other cases, buildings collapsed and fell toward the southeast. It should be remarked 
that practically all houses moving to the southeast were those situated on the streets 
running northwest-southeast. Very few buildings on the avenues (running northeast- 
southwest) were moved at all. The moved buildings stand approximately at right angles 
to the fault-line southwest of Stanford University. 
A change in the direction of the earthquake movement is suggested by the fact that in 
several cases the chimneys were apparently twisted from their normal positions. The 
same is true of several houses that collapsed. The twisting was clockwise in some 
cases and counter-clockwise in others. A remarkable case of twisting was shown in the 
house at 727 Cowper Street, where picture frames were tilted from the normal positions. 
Chimneys were mostly knocked down, those that remained standing being for the most 
part in the centers of the houses. The direction of their fall was apparently accidental. 
A curious case is that of three 1-story frame houses, exactly alike, at 317, 323, and 
329 High Street. The chimney on the house at 329 remained standing, while the 
chimneys on the other two houses fell. 
The data upon which these conclusions are based follow: 
737 Channing: Small one-story frame house without foundation; chimney standing. 
845 Webster: One-story frame house with wood foundation; chimney standing. Chimneys were 
thrown from the two one-story fraine houses next to it. 
434 Middlefield: Two one-story shingle houses; chimneys standing. 
427 Middlefield: One-story house; chimney in the center of the house stood. Next door, same kind of 
house, chimney at end of house fell. 
667 Hamilton: One and one-half story frame house; chimney in center of house stood, while one at 
side of house fell. 
557 Hamilton: Two-story frame house; chimney standing.
