BEHAVIOR OF INDIVIDUAL STRUCTURES. 43 
columns. While the jacking up closes the cracks, it can not restore 
the original strength of the connection, which although not entirely 
gone has been reduced to a very small percentage of its former value. 
MURPHY BUILDING. 
The columns of the five-story Murphy Building, at the corner of 
Kearney and California streets, were constructed of corner angles 
latticed and filled with cinder concrete, the whole being incased with 
plastered metal lath, with a dead air space between. The floors 
consisted of cinder-concrete arches between channels. 
This building was completely gutted by the fire, although the 
structure itself was left in fair condition. The metal-lath ceilings 
and partitions stood the test fairly well, though some of the parti- 
tions were buckled out of shape. A view of this damage on the third 
floor is shown in PL XLI, B. The terra-cotta trimmings and the 
copper work around the bay windows were badly damaged by fire. 
MUTUAL LIFE BUILDING. 
The nine-story Mutual Life Building, at the southeast corner of 
Sansome and California streets, was fireproofed throughout with 
terra-cotta hollow tile, with hollow-tile partitions. The treads of 
the cast-iron stairways and the wainscoting and tile of the corridors 
were of marble. The office floors were constructed of cinder con- 
crete covered with wood. 
The damage to this building from the earthquake was very slight. 
The fire in the building, while not severe, was sufficient to cause the 
failure of the tile fireproofing of the roof trusses, which collapsed 
from exposure to heat (PI. XLII, A). 
The recently completed eight-story building of the Pacific States 
Telephone and Telegraph Company, on Bush street between Grant 
and Kearney streets (PL XLI, A), embodied many good and a few 
bad features of construction. The side and rear walls were of brick, 
and the front was of terra-cotta pressed brick and terra-cotta trim- 
mings. All the walls were self-supporting. The floors were of reen- 
forced concrete between steel beams, and the ceilings for all floors 
above the basement were suspended metal lath, plastered. 
The walls were cracked somewhat by the earthquake, and the 
pilasters on the exterior were spalled. The girders and columns 
supporting the floors were fireproofed with concrete and were in 
excellent shape after the fire. The window protection was excel- 
lent; the front was provided with Kinnear rolling shutters, with 
plate-glass metal-covered windows, while the side windows had;
