Scientific Studies for Warwickshire Photographers.— 
Archaeology — the study of the past,—and Ethnology—the 
study of the inhabitants of the district at the present day— 
we have already touched upon. But there is much work also 
to be done in Geology, Botany, and Zoology. 
The Geology of Warwickshire. —The coloured maps 
issued by the Geological Survey show the different strata of 
which the surface of the county is composed ; and in a book 
which I wrote in 1881 * a general description of the rocks of 
the county will be found. 
Every landscape depends for its main outlines upon the 
rocks which lie beneath the soil; and for those who can 
“ read the rocks the study of the scenery of any district has 
a double pleasure. The oldest rocks of Warwickshire are 
the Cambrian quartzites and shales which lie between 
Atlierstone and Nuneaton. These had been wrongly assigned 
to the Carboniferous period by the Geological Survey, and 
the discovery of their true age was made by Professor Lap- 
worth and myself in 1882. The quartzites (altered sand¬ 
stones) are magnificently exposed in a series of immense 
quarries, and they are traversed by great masses of dark 
igneous rocks. The shales are well seen in the Stockingford 
railway cutting. 
In the Warwickshire coal-field, photographs of the surface 
works, collieries, and colliers might be secured; while, 
descending beneath the surface, the flash-light would enable 
us to secure interesting records of the mines and miners. 
Of the Triassic strata which succeed, there is a fine 
section of the red sandstone, sixty feet in vertical height, at 
Hockley Cemetery, in Birmingham. Elsewhere the Triassic 
rocks are but seldom exposed, ana we must be content with 
noting the level plains and rolling hills produced by their 
marls and sandstone. 
The Liassic strata—limestones and clays—which rest 
upon the Trias, are quarried at Wilmcote, Binton, etc., in 
* “ Geology of the Counties of England, and of North and South 
Wales.” Kelly and Co. Now out of print.
