would appear to succeed one another with considerable regularity 
from W. to E., and one bed, No. 1, would appear the deepest; but 
the top of the hill having been preserved, the beds can be seen plainly 
bending and folding themselves in two. There is a circumstance which 
renders it extremely easy to follow the beds along the hill-side and 
it is this, that the layers 16, 17 and 18 forma sort of broad ribbon at 
their outcrop ; 16 and 18 being composed of dark grey walls of: lime- 
stone which, from their hardness, are prominent 2 or 3. feet over 
the general surface of the slope, whilst 17, the layer between them, 
is a pale sandstone, decaying fast and forming a sunken furrow be- 
tween the two walls. This broad ribbon, about 30 feet wide, can 
be followed with the eye for miles. The layers 7, 8 and 9 also form 
a ribbon, but less well marked than the other, being paler and not 
so sharp. Now, these two ribbons are of the greatest assistance 
in following the twists and foldings of the beds. We have seen 
that the ribbon 16, 17 and 18 ascends. the eastern branch of the fold 
over Weean and curves over at the top of the hill, where its beds are 
perfectly horizontal, and then descends along the western branch. We 
see the two ribbons forming near the village of Kohew an anticlinal 
similar to that of Weean, but not quite so sharp, and the description 
of the ribbon also shows us plainly that the beds of the Weean 
hillocks are reversed. here isa great fault between the main hill 
and these two little hillocks of Weean and Kohew; on the north 
of the fault, the beds dip to the N. H. ata high angle, and all the 
soft and marly layers have decayed and tumbled down in éboulis,* 
but the hard ribbon has remained, and can be traced along the 
hill showing the outcrop of the beds. All the way up to Nawan 
we can see the beds of limestone dipping N. HE. and we can infer the 
existence of many faults across the range from the reappearance of 
the ribbon on the top of each small spur which descends in the 
Kohew valley. We see these pieces of ribbon plunge under the soil 
of this small valley to emerge on the other side (fig. 7), giving us 
the strike of the beds of that long chain of limestone hills which 
connects Nawan with the Wastarwan Mountain ; but although I have 
* The French word is so convenient and expressive, that I do not hesitate 
to use it, as no Knglish word expresses equally well the broken materials of 
beds which have slipped.
