at Swithland and Bardon, the floor beneath the Keuper is rough and 
craggy. 
The Nature of the Deposits —Every where the beds dip in the direction 
of the surface slopes on which they le, and the amount of dip depends 
upon the steepness of the slope. Catenary bedding is seen at Croft 
and Groby. Near the rocks the marl contains grit and stones, and 
there is generally a breccia at the base. The stones are of varied 
sizes, sometimes worn and sometimes very angular.’ They are in 
a remarkably fresh condition. 
Both stones and grit are derived entirely from the particular rocks 
which the beds containing them surround. In these beds there is 
often a small amount of quartz sand, sometimes apparently wind- 
worn. It yields the same heavy minerals as the Upper Keuper 
Sandstone. 
In many cases, e.g., around the South Leicestershire igneous rocks, 
this sand cannot be of local origin. 
At Croft some of the Upper Keuper Sandstone consists of almost 
spherical grains, and appears to be a desert sand. 
Near Leicester the sandstone is uniformly false-bedded from the 
south-west, and F#stheria and fish-scales occur upon the false-bedding 
planes. Heavy mineral separations have been prepared from a large 
number of localities throughout the country. The mineral grains are 
generally very much worn. The most plentiful are garnet, magnetite, 
zircon, tourmaline, and rutile. 
In the normal Keuper Marl bands showing false bedding, ripple- 
marks, and salt pseudomorphs are generally common. 
But such evidence of subaqueous deposition as there is points 
rather to the existence of occasional streams and salt pools than to the 
deep waters of one great Keuper lake. 
It is inferred that the Upper Keuper is a desert accumulation.

Rocks at Barpon Hirt. By W. Keay, Assoc. M. Inst. C. E., and

ARDON HILL is situated in the Charnwood Forest area, about 
ten miles north-west from Leicester. The hill rises to an 
elevation of 912 feet, and is higher than any of the land intervening 
between this point and the German Ocean. 
The hill consists of Keuper marls resting unconformably upon 
Pre-Cambrian rocks, the latter protruding about 100 feet through 
the marls. 
The object of this paper is—(1) To remark upon the unusual 
elevation of the Keuper marls. (2) To consider the probability of 
the entire submergence of the hill during the Triassic period. 
1. Elevation.—Acting upon a statement of Professor Phillips that 
“the Triassic system offers the remarkable fact of never rising to 
elevations much above 800 feet,”’ the authors by personal inspection, 
where possible, and by the aid of ordnance levels failed to discover 
any point on the Trias in England reaching a greater height than 
800 feet except at Bardon Hill. Here, ‘skerry’ bands in the Keuper
