metallic ores, are also known now to be confined to certain ranges of 
strata in the interior, and on the western side of our Island and in those 
parts confined to certain narrow ranges called veins ; but the courser 
kinds of minerals, such as all kinds of stone, sand, clay, &c., wh. 
are stratified, and apphed to many useful purposes are, on account 
of their now well known regularity and continuity, good sources of em- 
ployment and profit. No place can be better stored with the articles 
than the greater part of this Island. They in former times, seem 
however to have been little attended to, as in the time of Sir Robt. 
Walpole and probably much latei, the streets of the Metropolis were 
paved with Bremen stone. Purbeck stone was much m use since I 
can remember, which gave way to the finer flags from Yorks., first 
introduced by Sir Wm. Stains, and the great employment this kind of 
stone affords, and the profits thereon, between the quarries and their 
place in the pavement of London and numerous other great Towns, 
is become a settled national benefit, and to which many new and 
extended uses of freestone, slate, flints, &c., have largely contributed. 
All the best kinds of Pottery called Delft-ware, was formerly im- 
ported from Holland, the clay for which, to the disgrace of the country, 
was taken from our shores, but which, to the immortal memory of 
Wedgewood, has become a permanent source of employment to many 
thousands of men, women and children, in the populous but new 
district of Etruiia. This manufacture to my knowledge is capable of 
great extension, and which, like the Iron Trade, from the raw materials 
being our own, is one of the best that the country can encourage for 
the emplo}T2ient of labour and capital, and that even to any extent for 
exportation. Flags and Grindstones are the accompaniments 
of coal, and therefore from their quantity, quality and accessibility, 
Britain, to the advancement of labour and commerce, might supply 
all the world with these articles. Flints are most extensively used 
in potteries, which, like the pipe clay, are the chief minerals of value 
in the south-eastern part of the Island, but to calcine the flints and the 
ware, these articles go to the coal districts. 
We now come to the most valuable nxineral in the Island, the Coal, 
wh. seems to be drawing a variety of employments into its own vortex, 
and with the whirling rapidity of its appendant machinery, is employed 
not only to make but to convey the made and unmade, with the velocity 
of the wind, to and from all parts of the world. Now, if we look to 
a Geological Map for the sites of Coal, we find three of our principal
