country, one crosses the Loma-loma ridge, elevated 1,000 feet, on 

 the top of which was once situated the village of Loma-loma 

 visited by Home in 1878. The rocks exposed on the surface are 

 scanty, a hard palagonite-tuff, which owes its induration to a 

 calcitic cement, occurring on the upper part of the ridge, the 

 original site of the village being marked by a large block of this 

 stone. 1 The track then descends into the valley of the Loma-loma 

 river, about 400 feet above the sea, in the bed of which occur 

 blocks of an amygdaloidal basaltic andesite, containing phenocrysts 

 of both rhombic and monoclinic pyroxene, and referred to genus i

of the rhombic pyroxene andesites. The amygdules are formed of 

 calcite. 



Beyond the river the ascent of the northern slope of Va-lili 

 begins. As high as 1,100 feet occur basic agglomerates overlying 

 fine and coarse palagonite-tuffs, which are at times horizontally 

 bedded, the finer kinds being sometimes calcareous, and like that 

 of the Loma-loma ridge above mentioned. At 1,300 feet is a line 

 of tall cliffs which extend for some distance at intervals along 

 the mountain-slope, and are indicated by some fine waterfalls. 

 My track struck these cliffs at a place named " Nangara-ravi " (the 

 leaning cave-rock) where they have a height of 1 50 feet or more. 

 The tall cliff leans slightly forward, so that it forms a shelter at its 

 foot, and hence the name. It is composed of a tuff-agglomerate, 



1 I did not find any foraminiferal shells or other organic remains either in 

 this tuff or in the similar tuffs occurring on the adjacent slope of Va-lili up to 

 1,100 feet. My specimens, however, are very small.
