84 REPORT — 1900. 



to have been very strong. It was felt over the whole republic At 

 Colinia, on the Pacific side, it had a duration of Im. 20s., and on the 

 Atlantic side, at Vera Cruz, it lasted 10s. 



By the method of circles and by the method of preliminary tremor 

 intervals I place the origin at a point 30° distant from Victoria, and 34° 

 from Toronto, or near to lat. 19° N. and 105° W. long. On January 20, 

 1900, 'No. 381 was recorded in Mexico with time intervals similar to 

 those for No. 250. The preliminary tremor intervals for this referring to 

 Victoria, Toronto, and Kew read 13, 15, and 38 minutes, indicating that 

 the Kew reading for No. 250 is the lower of the two values given. 



The time readings for 248 clearly correspond with that for an earth' 

 quake with a similar origin. 



294. An origin S.W. of Jamaica roughly agrees with the time differ- 

 ences between Toronto, Victoria, and Shide, and the preliminary tremors 

 duration for Kew and Toronto. 



371. In 'Nature,' April 19, 1900, we read that on December 25, at 

 12.25, an earthquake took place in S. California. In the villages of San 

 Jacinto and Hermet every brick building was damaged. 



Professor F. Stupart sends me the following extract from a newspaper 

 clipping : 



Los Angeles, Cal., December 25, 1899. 



The towns of San Jacinto and Hernet, in Riverside County, were 

 badly shaken by an earthquake at 4.25 o'clock this morning. In San 

 Jacinto not a brick house or block escaped injury. Nearly all of the 

 business portion is in ruins. The new Southern California Hospital caved 

 in. It was not occupied. At Hernet the Hornet's Company mill is 

 partly down. The front wall fell flat. The rear of the large Johnston 

 block also toppled over. Hernet's new hotel is a ruin. The damage at 

 those places cannot be estimated now. Communication by wire is inter- 

 rupted. The ' Herald ' has received a telegram from San Bernardino saying 

 that six Indians were killed at Hernet by falling walls during the earth- 

 quake. The Santa Fe raUroad report is to the effect that no lives were 

 lost. 



Los Angeles, December 25. — The total damage at San Jacinto and 

 Hernet is estimated at ^50,000. No person was injured at either place so 

 far as known. The shock was heavy at Santa Ana, Anheim, San 

 Bernardino, Riverside, and other places, but no particular damage is 

 reported except from San Jacinto and Hernet. In this city no damage 

 was done, though the shock was particularly violent. The houses here 

 are well filled with Eastern tourists, and they were in many instances 

 terrified at the unexpected disturbances, and rushed from their rooms. 



San Diego, Cal., December 25. — The most severe shock of earthquake 

 experienced in this city in fourteen years took place at 4.25 a.m. to-day, 

 and was accompanied by a loud rumbling noise. The taller buildings 

 in this city were severely shaken, but no serious damage was done. A 

 high wave struck the beach ocean front, but no ^damage was done. A 

 slight shock followed the first a few seconds later. 



268. The time intervals for Shide, Victoria, Bombay, and Toronto 

 suggest an origin near to that given for 322, with which the preliminary 

 tremors for Victoria and Mauritius accord. In the British Association 

 Report for 1899 this origin was placed on the western side of the 

 Atlantic, but additional data having since been obtained this is now 

 modified.
