were discovered? Not as to-day I am sure, but more or less like Morro del Spartan 

 at Santa Clara, as already suggested by Johow p. 261. I would think that 80, in 

 some valleys 90 per cent of the soil is now occupied by introduced weeds. We 

 have no reason to believe that there was a desert when the immigration of aliens 

 began. 



It is to be regretted that we did not study how the shells found did occur, 

 if only on the surface or also deeper down embedded in the sand. And we have 

 to find out if landshells live on the plants mentioned above. 



With Pta de la Isla we reach the end of the north coast. Time did not 

 permit us to visit the small peninsula W of El Puente, and we shall now pro- 

 ceed along the south side of Masatierra. 



Pta O'Higgms, watched by a nameless morro (small skerry), and the inhosp- 

 itable coast cliffs of BaJiia Carvajal are seen in fig. 47. With a XW wind 

 boats engaged in langost fishing at Santa Clara find shelter here. From Pta 

 AgiiabueJia to Co Negro the coast shows several well-marked bights. 



BaJlia Tierra Blanca or Tierras Blancas has its name from the white sand 

 above the bay. Just as the other bays on this coast it is bordered by cliffs and 

 beaten by a never-resting surf. To land anywhere on this side of the island is 

 possible only under very exceptional conditions (fig. 48). 



Pta Larga (Long Pt.) separates Tierra Blanca from the next bay; in the 

 background rises a rounded hill which I take to be identical with Guzman's Co Enri- 

 que. From a distance it seems to be formed by basalts of the higher horizons, but 

 no specimens were brought. 



Baliia Cliup07ies derives its name from "chupon", in Chile a vernacular name 

 for Greigia spJiacelata Reg. (Bromeliaceae), which has edible fruits (chupar = suck), 

 and applied by the fishermen of Masatierra to the extremely rare Hesperogreigia 

 as well as to OcJiagavia\ in this case the former, an inhabitant of the wettest 

 and loftiest ridges, is not to be thought of, whereas the latter, a typical xerophyte, 

 very likely occurs here, even if we did not observe it W of Tres Puntas, where 

 it covers rock faces (see Skottsb. 3 PI. 97). The slopes round the bay are grass- 

 land, in the western half almost pure Avena barbata, otherwise with extensive 

 patches of the native Stipetum. All streambeds in this western section are dry 

 most of the year. 



Loina Escarpada\ 385 m high where we crossed it near the main range, 

 separates B. Chupones from \"illagra Bay, this taken in a wide sense. Off the 

 point lies Morro llnil/o (vifiilla means "small hill planted with vines", but the 

 name must refer to something quite different in this case); the gradient of the 

 surface shows the tilt of the lava beds (fig. 49). 



Bahia de Villagra and its valleys, the bay taken in a wide sense and 



' In my field notes I called this ridge "Cordon Escarpado", and this name also appears 

 on the Chilean chart, and on my map I had used the same name for the ridge between Pangal 

 and Q. Minero, and as it was published in this sense Skottsb. 3 pp. 890, 915 . I have renamed 

 the other ridge Loma Escarpada.
