Fig. 3. Hydrotherm figure for Bahi'a Cumberland, Masatierra. The figures to the left denote 

 degrees Centigrade for the temperature curves (the continuous lines) and centimetres for the 

 precipitation curve (the broken line). A means of daily maxima, B mean temperature, C means 



of daily minima. 



ed ridges luxuriate under conditions different from those prevailing at sea-level 

 in Bahia Cumberland. Here the daily extremes correspond more or less to those 

 observed on the opposite mainland where, however, the summer is practically- 

 rainless and no hygrophilous forest able to exist, and the conditions 2 1/2 degrees 

 farther south are essentially the same. Not until we reach Punta Lavapie do we 

 meet with conditions similar to those found in Bahia Cumberland, but the graphs 

 figs. 3 and 4 show that at Punta Lavapie the rainfall is smaller and the tetnper- 

 ature lower, about the same as at the Centinela station on Masatierra, 345 m 

 above see-level, if we are permitted to use the short series from there. It is to 

 be regretted that there is not a single coastal mountain station in this part of
