230 REPORT OF THE CALIFORNIA EARTHQUAKE COMMISSION. 
Along the same line, near the corner of Waller and Portola Streets, is a little locality of 
sharp intensity, quite within the lower range of Grade B. It occupies about a block. 
In the adjoining blocks chimneys fell generally, houses were disturbed slightly on their 
foundations, and foundation walls were cracked. Here a thin layer of sand occupies 
the bottom and lower slopes of a sharp little valley. There are low serpentine hills just 
to the east, with higher chert hills to the west. 
In the vicinity of the corner of Van Ness Avenue and Clay Street, there is a low place, 
or saddle, in the crest of the sandstone ridge where, without apparent lithological cause, 
there were manifestations of some violence. Some apparently good buildings displayed 
conspicuous cracks. It is believed that this damage may be in part ascribed to explosions 
of dynamite used in checking the fire, but in many cases the cracks do not appear to be due 
to this cause. There is doubt as to the meaning of the evidence here. 
In the western part of the city proper, the Richmond district, the Sunset district, and 
Golden Gate Park, there are several places where chimneys were quite generally destroyed 
and houses were shifted slightly on their foundations. Loose sand covers the rock to an 
unknown depth, but this mantle is probably not very thick. 
Lake Street, in the vicinity of Fifth, Sixth, and Seventh Avenues, is one of these local- 
ities, where, for instance, the Maria Kip Orphanage exhibited conspicuous cracks in 
its brick walls, as well as fallen gables. In the Home for the Aged, not far away, cracks 
in the brick walls were numerous. Dwellings of wooden frame construction were less 
seriously damaged; but even these were much more noticeably affected than others at a 
little distance. The buildings of these charitable institutions were probably not very well 
constructed. 
A smaller area, on Eleventh Avenue between California and Clement Streets, shows 
one frame dwelling quite ruined by collapse. (See plate 88a.) This was due to the giv- 
ing way of a high-posted wooden underpinning. Houses near by are comparatively 
little affected. It is suggested that this locality is a place filled by grading. 
Along First Avenue, between Point Lobos Avenue and A Street, a considerable length 
of the west wall of the Odd Fellows Cemetery was thrown over to the east. This was a 
concrete wall 5 or 6 feet high, with a thickness at the base of from 1 to 1.5 feet. It was 
reenforced near the top by a 2-inch gas pipe running the length of the wall. Houses 
on the west side of the street were slightly shifted on their basements. 
On Third Avenue, between Point Lobos Avenue and Clement Street, the underpinning 
of houses was disturbed. 
The French Hospital buildings, which occupy the entire block bounded by Point 
Lobos Avenue, Fifth Avenue, A Street, and Sixth Avenue, showed ugly, X-shaped cracks 
in the brick walls, especially in the central towers. Some brick work fell from the gables, 
and the chimney stack was broken. 
In this part of the city buildings are isolated or in small clusters, with unbuilt districts 
of blown sand intervening. Consequently evidence was scarce and unsatisfactory. 
The Park Emergency Hospital, near the southeast corner of Golden Gate Park, had its 
walls badly cracked and its gable thrown out. It is a small, 1-story, sandstone building, 
with a wooden frame. Its site was loose sand of unknown depth, probably extensively 
graced. Evidently it was not an ‘excellently built structure. The restaurant at the 
children’s playground in the Park was wrecked. (Plate 86.) 
The Museum in the Park, not far from the corner of Eleventh Avenue and Fulton Street, 
was a wooden framed building, with brick and plaster walls. These were cracked very 
badly, and considerable portions fell. Near by considerable brick and stone fell from the 
cornice of the music stand. Ugly cracks traversed the hemispherical arch, constructed 
of sandstone blocks, which served as a sound reflector. The building was made of sand- 
stone blocks, backed with brick. In some of the columns, several of the blocks are moved
