by two permanent streams, which receive several small tributaries from the 

 surrounding gullies. The valley bottom was cleared of its native forest centuries 

 ago; already 80 years ago practically nothing was left below 250 m. Macales and 

 maqui-luma stands fill the interior, and only farther up the gullies we find better 

 forest. Material washed down from the sides have contributed to build the wide,^ 

 stony and sandy beach, the largest piece of level ground on this island (figs. 3, 

 20, 27). I cannot remember having heard of any names for the streams. Guzman 

 mentions 3 streams emptying in Cumberland Bay, Arroyo del Hospital, A. de la 

 Turbia (turbio = turbid) and A. de la Reina; the first is, I suppose, where Anson 

 had his hospital. 



El Pird))iide (figs. 21, 29, 31), separated from Mt. Yunque by a narrow saddle 

 (W Portezuelo del Yunque), towers above the colony. Johow's PI. V dates from von 

 Rodt's reign and shows the scenery when no village existed. The figure 809 m 

 on Friederichsen's map stands for the summit of Mt. Piramide. From both N and 

 S the ascent is rather steep, 40 — 50° the first stretch, but gets more gentle higher 

 up, 25 — 20°; toward the valleys on both sides the slopes are precipitous (Skottsb. 



3 PI. 9i).

 at his disposal, fails to visit this famous spot with the Selkirk memorial tablet. The
