Appraisers’ Building, San Francisco. 



Mint. — Fig. 54 shows by number, as in the former cases, the positions of the stations 
occupied and the points at the corners are indicated by their orientation. 
The southwest corner is the lowest, being 0.498 foot = 5.976 inches (mean) below the 
northwest corner. The walls on the north side are badly scaled by the heat. No serious 
cracks were noticed in the outside. The rod was held on top of the water-table at each 
extreme corner of the building. Street cars constantly passing on both Mission and Fifth 
Streets, also heavy drays. The wind was very troublesome. Sights were nearly equal. 
The deformation indicated by the above measurements can not be wholly referred to 
the earthquake, since it is quite probable that the structures had settled somewhat before 
that event. It appears, however, to be desirable to put the measurements on record for 
future reference.
