ON THE NATURAL HISTORY OF THE FARALLON 



ISLANDS. 



GEOLOGY AND BOTANY BY J. W. BLANKINSHIP. 

 ZOOLOGY BY CHARLES A. KEELER. 



Thirty miles west of the Golden Gate, in the Pacific, are the 

 Farallon Islands, composed of three groups, called the North, 

 Middle and South Farallones, and various rocks and shoals. They 

 have a general northwest and southeast trend, parallel with the 

 coast, and from Noonday Rock on the North to the South Faral- 

 lones is a distance of about eleven miles. All except the extreme 

 southern are mere points of rock in the ocean, the largest being 

 only 160 yards in diameter. 



The South Farallon is nearly a mile in length from east to west, 

 and about half that distance in its greatest width. Its greatest ele- 

 vation is 343 feet, and upon this peak the lighthouse is situated. 

 The island is visited each week from May to July by the eggers, 

 but at other times it has only occasional communication with the 

 shore by means of tugs and the lighthouse tender. It is chiefly 

 noted as the largest sea-bird rookery on the Coast. The following 

 notes refer only to the South Farallon Island, and as the result of 

 a two-days' collecting excursion, can hardly claim to be more than 

 a very general survey.
