294 REV. J, F, BLAKE ON A REMARKABLE INLIER [| May 1902, 
400 yards distant, has now a summit-height of about 140 feet 
above the present highest point of the stack, which is all the 
information that we can obtain about it here. 
About half a mile to the north, however, is the opening of the 
gorge of Gartymore Burn, of which a general section is given in 
Prof, Judd’s memoir, In this gorge we have a complete view of 
the relations between the breccia-beds and the Caithness Flags, At 
Fig. 3.—Breccia-bed overlying Jurassic shale, close to the junction 
with the Old Red Sandstone, Gartymore Burn, mm a much 
thicker mass. 
[From a photograph, | 
the’ mouth of the gorge is seen the section represented by Prof. Judd’s 
fig. 16,' of the correctness of which as a diagram the photograph 
(fig. 2) reproduced on p. 293 bears witness. The rise towards the 
land is doubtless the result of later tilting, at the time when the 
granite was pushed up, and dragged with it some of the adjacent 
strata.
