encouraged the delusive hope of rich mines. A few miles down the ' 

 river Paxaros, from where the road to San Juan crosses it, there are 

 thermal springs, and sulphur iii their neighbourhood. On the Santa 

 Cruz side, near the Mission, there is said to be coal, but it has never 

 been mined. Along the east shore of the Bay of San Francisco, for 

 thirty-five miles east-southeast, from beyond the Island of Molate, 

 towards San Josef and Santa Clara, the harbour is bounded gener- 

 ally by low alluvial soil, and only in a few places do low and rocky 

 cliffs protrude. Near the Mission of San Josef there are some hot 

 springs in the plain, surrounded by a verdant covering. Earthquakes 

 are rather common, and one in 1806 so shook the building of the 

 Mission of Santa Clara, that a new one was obliged to be erected. A 

 few years ago, a boat belonging to a whale ship, when lying in several 

 feet water, was suddenly thrown on the beach and left dry, and a 

 vessel in the Bay of Monterey was suddenly and severely tossed 

 about by the sea, and the shock was felt on the shore at the same 

 time. At ten o'clock on the 26th December, 1827, a slight shock 

 was felt at San Josef. The shocks are said to come along the coast 

 from the northward, and when they are also felt at IMonterey it is 

 some minutes later. 



"One was perceived at the Presidio of San Francisco in the month 

 of April, 1827. It continued a short time, but the shaking was so 

 slight that it injured nothing. — C."
