rock of which they consist is that which forms so large a portion 
of Rum and of Skye.’” (Yol. i. p. 467.) 
With reference to the conjecture that these red sandstone boulders 
in Sandy may have been transported from Rum or Skye, a proba- 
bility of its correctness is afforded by the circumstance that the red 
sandstone rocks of Rum and Skye are situated on the sides of these 
islands facing Sandy and Canna. 
VIII. — HARRIS. 
1. At Rodel, the south end of Harris, there is a hill called 
Strondaval, 638 feet high. It is steep and rocky on all sides, 
especially the west and south. The Convener, under the guidance 
of Lord Dunmore’s gamekeeper, scrambled along its south and east 
sides, and found that the smooth faces of the rocks all looked 
towards the W.1ST.W. On the east side of the hill there was an 
entire absence of smoothed rocks. That side had apparently been 
the lee side, not having been grated upon by the agency, whatever 
that was, which had smoothed the west side. 
There were many boulders on the hill, chiefly angular ; some 
pretty large, hut none of any special interest. 
2. At Borve, on the west coast, about half-way between Rodel 
and Tarhert, there is a remarkable accumulation of boulders on the 
side of the hill, sloping down to the sea. The general dip of the hill 
(which reaches a height of about 800 feet) is towards the west or 
west by north (magn. ). The rocks are of gneiss, and present a series of 
beds, layers, or benches more or less horizontal, forming, as it were, 
a gigantic staircase along the hill face for about half a mile, several 
hundred feet high — all more or less covered by boulders. These 
benches of rock, in many places, show that they have been rounded 
by severe pressure from west by north. The boulders which lie on 
them give evidence of transport from the west. 
Fig. 23 is intended, by a sectional view of the hill, to show 
the disposition of its rocks and the position of the boulders on 
them. 
Fig. 24 gives a view of two boulders lying on a portion of the 
rocks forming the hill just mentioned. The position of both indi- 
cates blockage and stoppage on their east sides. Their own relative 
positions afford similar evidence.
