206 EARTHQUAKES ON THE PACIFIC COAST 



stands some distance from the scene of the explosion. It will 

 probably not explode. No greater scene of desolation could l)e 

 conceived than that presented after the explosion. Everything 

 belonging to the buildings was smashed into matchwood. 



Over the little hill were the cottages of workmen and residences of 

 Judson and his superintendent. Here most curious freaks were 

 seen. One whole side of Judson's house was ripped off, and the 

 plastering was all torn off and covered his fine furniture. In the 

 other house the main stairway was twisted completely around, 

 and one chimney had also been whirled completely about, the 

 top falling off outside. All the little cottages were wrecked so 

 badly that they can never be repaired. All that can be done is 

 to tear them down. The escape of the inmates was miraculous. 

 Only one boy was seriously hurt. He had his arm broken. 



One of the largest windows broken in San Francisco was that on 

 the south side of the First National Bank building, corner of 

 Bush and Sansome streets. The Baldwin Hotel was damaged, 

 and windows on several floors were smashed to pieces. The two 

 panes of plate glass in the windows of the San Francisco clearing 

 house, at 211 Sansome Street, were the largest in the city. The 

 one on the south side was shattered into small pieces, and the 

 pane on the north side was uninjured. They were seven-six- 

 teenths of an inch thick, and each cost $600. The glass in most 

 of the windows of the American sugar refinery was broken.

The explosion of the giant-powder works made a record on my 

 seismograph, the maximum displacement of the pen in a north 

 and south direction being 4 mm. and in an east and west direc- 

 tion 4 mm'. (C. D. Perrine.)

Mr. F. G. Blinn reports that his seismograph was not in working 

 order, owing to the fact that the soil is adobe, and as it had not 

 been irrigated for some time the working of the soil caused the 

 pen to creak so much that any attempt at records was aban- 

 doned. After the powder works explosion the pen was found 

 off the plate on the east side making a nearly straight line, and 

 this would indicate a motion of the ground to the west. (The 

 powder works were about northwest.) A pipe lying on a shelf 

 in the observatory was thrown on the floor to the east, thus con- 

 firming the motion of the seismograph. There was an item in 

 the San Francisco Evening Bulletin saying that the sealing 

 schooner Emma and Louise, then 150 miles off shore, felt the 

 shock heavily, and it was thought she had struck a rock.
