of descending mist, hovering over the surface of the 

 pool; while, on the eastern side, the foaming water fell 

 like an endless system of inverted rockets, or like an 

 inverted succession of dense smoke-wreaths. 



Owing to the comparative smallness of the fall, a very 

 good view was at times obtained of the cavelike recess 

 of the cliff behind, which must continuously be hollowed 

 out to a great width in the sandstone, by the strong 

 backsplash of the water below, and to a less width by 

 the everpresent supersaturation of the rock higher up, 

 down the greater part of whose face water must 

 continuously be trickling. The recess extends sloping 

 upwards and outwards to but a comparatively short dis- 

 tance from the top of the cliff, apparently to the line of 

 the intensely indurated conglomerate which forms the 

 river bed above. Though vertically of great extent, this 

 recess is narrowed laterally, and must be almost hidden 

 from direct observation long before the fall has reached 

 its full width, though a lateral view of its basal part 

 might be obtained from a favourable position. Dense 

 masses of vapour drifted at intervals out of this recess, 

 and generally they floated upwards over the edge of the 

 precipice ; but occasionally they were driven outwards 

 and downwards over the pool into the open valley. 



The edge of the cliff along the river bed is markedly 

 irregular, due to the breaking away of parts of the con- 

 glomerate by the force and washing of the water; and 

 it was owing to this that in this very low state of the 

 river, the fall was broken up into the small channels on 

 the western side. Apart from this, however, the appear- 

 ance of the fall must be considerably changed at those 

 long intervals, when, by the continuous disintegration of
