INTRODUCTION. XXlll 



able quantities of rich argentiferous galena have been smelted out at CeiTO 

 Gordo, near Owen's Lake. The production of quicksilver was larger in 1868 

 than ever before, the exportation of the year having amounted to 43,000 

 flasks, or 3,268,000 lbs. The tin lode at Temascal has been well opened, and 

 found to be wide and rich; and preparations are being made to extract the 

 ore in large quantities. 



The growth of San Francisco has been rapid. The population of the city 

 was 2,000 in July, 1849; 25,000 in December, 1850; 60,000 in December, 

 1855; 83,000 in August, 1861; 119,000 in August, 1865; 131,000 in July, 

 '1867; 150,000 in July, 1868, and it is 160,000 in March, 1869. In 1868, 

 59,000 passengers arrived at this port by sea, and 25,000 departed, leaving a 

 net gain of 34,000. The vessels which entered the harbor in the same pe. 

 riod numbered 3,300, and measured 1,000,000 tons. The exports of mer- 

 chandise and domestic produce were valued at $22,000,000. The sale of 

 real estate in San Francisco amounted to $27,000,000, and of mining and 

 other stock to $115,000,000. The mining and other companies incorporated 

 in San Francisco, paid $5,000,000 of dividends. The widening of Kearney 

 street has been completed ; the extension of Montgomery has been com- 

 menced ; the stone Dry Dock at Hunter's Point is in working order, and the 

 city is growing rapidly. Vallejo, Oakland, Sacramento, Stockton and Marys- 

 ville, are all more prosperous than they have been at any time within ten 

 years.
