1 68 A YEAR OF COSTA RICAN NATURAL HISTORY 



cular plaited leaves which we saw in the crater of Irazu. The 

 constant spray and the evaporation from the cold water 

 no doubt keep the temperature of this place much lower 

 than that of the surrounding forest, enabling such a moun- 

 tain plant as Gunnera to live here. 



The day was unfortunately cloudy most of the time, 

 with drifting masses of cloud and mist in all the valleys so 

 that we were quite unable to photograph the beautiful 

 vistas of hills and valleys. This we regretted very much as 

 it is unlikely we shall ever be along this road again. It is a 

 difficult trip from Cartago and we would not have seen these 

 falls except for Mr. Lankester's kindness. The Orosi Falls 

 are well worth any labor required to reach them and our 

 trip thither was one of the finest and most beautiful we had 

 in Costa Rica.
