CAMBRIAN ROCKS AT DUSTHILL. 
268 
Another junction of Cambrian shales with trap-rock is 
found just south of the little cross road—a cul-de-sac—which 
leads to a house near the highest point of the ridge; and 
there is another outcrop in the next field west of this. 
At the northern end of the Dostliill ridge the gardens of 
Dosthill Lodge occupy part of the site of an old quarry. 
The igneous rock here is of the grey decomposed kind, with 
a central harder vein. It can be traced northwards like a 
wall for some little distance, looking like a miniature Derby¬ 
shire “ edge.” A little further north still there is a roadside 
section of coal-measure shales and sandstones, in a line with, 
and east of Dosthill House. 
At the eastern part of the Dosthill ridge the Midland 
Railway cutting shows a fine and continuous section of 
sandstones, ironstone, shale, &c., cf Carboniferous age, 
including the outcrop or “ smut” of five coal seams. 
All the Carboniferous rocks here have a very high easterly 
dip, amounting to seventy-five or eighty degrees, where they 
are seen close to the line of fault which separates them from 
the Cambrian strata. Thus the latter are sandwiched, as it 
were, between Coal-measures on the east and Keuper Marls 
on the west. 
When the Dosthill mass was believed to be an intrusion 
of greenstone into coal-measures, it was reported that the 
coal was “burnt” at the junction. But old colliers and 
“viewers” whom I have questioned have described tome 
the coal seam as being broken and even reduced to powder, 
but they had none of them noticed any appearance of charring 
or coking. Doubtless all the effects observed can be explained 
by the breaking of the strata along the line of fault. The 
coal seams have here been followed vertically from their 
outcrop, and at the present time a line of collieries is in full 
work quite close to the fault, and within a few yards of 
Cambrian strata. In few places are they brought into such 
close proximity. 
Flora of Warwickshire.—I should like to correct a statement 
which occurs on page 255 of the last number of “ The Midland 
Naturalist,” in which Agrimonia odorata is said to be “new to North 
Warwickshire.” This I found at Austrey, near Tam worth, in August, 
1885. This is one of very many plants that I have been able to add 
to the Flora of North Warwickshire during the past twelve months. 
As the “ Flora” is being prepared for publication in the book form, I 
have not considered it needful to rush into print every time I have 
found a new plant, or a rare plant in a new station. I invite botanists 
to be obliging enough to send me notes of any new finds in Warwick¬ 
shire, and I shall gladly acknowledge them in the proper place when 
a new edition of the “Flora” appears.—J. E. Bagnall, 84, Witton 
Hoad, Aston, near Birmingham.
