Los Her.manos Islands. 



On Jan. 9th_, 1908, we steamed across the ten miles of 

 sea which separates lilanquilla from the Los Hermanos 

 Islets. A fresh trade-wind was blowing, and a strong 

 current was running between them, so that we had some 

 trouble in landing on Orquilla, one of the more northern of 

 the seven islets. 



The group is situated forty-five miles due north of the 

 north-west point of Margarita Island, which is itself about 

 twenty miles or more from the mainland of Venezuela. 

 They together occupy a space of about eight miles in a 

 N.N.W. and opposite direction, and consist of masses of a 

 granite-like rock (diorite), which rise more or less abruptly 

 from the sea. 



Orquilla, the only islet that we had time to explore, is, so 

 far as we could judge, about two miles or more long by a 

 mile wide. It rises to a height of 650 feet, and is covered 

 with a thick growth of cacti, agaves, and tall coarse grass, 

 while here and there are patches of sea-grape and fairly tall 

 mangrove-trees. Near the top, dense masses of tall, upright 

 Cerei grow to a height far above a man^s head. In the 

 short time at our disposal (about five hours) at least two- 

 thirds of the island was left unexplored, owing to the very 

 great difiiculty in making a way through the scrub, so that 

 it is possible that there may be other land-birds there which 

 we did not come across. At a height of 600 feet there is a 

 long, saddle-backed ridge, nearly a mile long, which wejiad
