Walla Walla (W. T.), December 9, 1887.— Several years ago a loud 

 explosion somewhere in the Salmon River Mountains shook the 

 whole country there, and reports of a volcano breaking out and 

 lava flowing over the mountain trails astonished the country. 

 The San Francisco Chronicle and Portland Oregonian sent reporters 

 there, but neither could find any trace of a volcano, though whole 

 forests were ablaze. Joseph Baker, of Mount Idaho, an old 

 miner, reports to the Walla Walla Statesman to-day that he has 

 discovered the scene of the explosion, near some new diggings. 

 The country for half a mile around is full of fissures new^ly 

 cracked, but there are many others covered with moss, denoting 

 previous explosions. — S. F. Chronicle, December 10, 1887. 



The place is only twenty miles from Mount Idaho. — W. W. States- 

 man, December 9. 



1879 to 1887. 



I am informed that between the building of the narrow-gauge rail- 

 road through the Santa Cruz Mountains (1879) and 1887, October, 

 there has never been any damage to the tracks from landslides, 

 etc., w^hich has been attributed to earthquakes. This w^ould show 

 conclusively that no very severe shocks have occurred. — E. S. H. 



1871-1887. 



There has never been any damage to the roadbed of the narrow 

 gauge railroad, from Saucelito to Russian River (Duncan's Mills), 

 which has been attributed to earthquake shocks. — Verbal account 

 of W. F. Russell, Esq.
