extracted, and other remains connected with Roman mining, 
have been found at Horsforth, at Adel, at Oakenshaw, at 
Scarcroft, and also in Leeds. When, about twelve years 
ago, they were carrying the sewerage down Kirkgate, in this 
town, the workmen came upon a great quantity of scoriae, 
&c, at so considerable a depth as to leave little doubt that 
smelting had been carried on there by the Romans. In the 
time of Thoresby, great heaps of these ancient cinders were 
found at Allerton Gledhow, from which circumstance that anti- 
quary supposed the name to be derived, for gled, in Anglo- 
Saxon, means a cinder. The lead mines of the Romans lay 
towards Craven, and appear to have been worked at a very 
early period, for some of the pigs of lead, prepared for 
transportation, have been found, bearing the name of 
Domitian — imp. caes domitiano avg cos vii — which carries 
us back to the first century of our era. Lead appears to have 
been considered at that time in the light of a very valuable 
metal, and that which came from Britain was especially 
esteemed, which was no doubt the reason why the emperors 
kept the mines in their own hands ; but they seem after- 
wards to have let or granted them to others, for we find no 
pigs of lead bearing the Emperor's name after the second 
century. 
Among other branches of the industry of the Roman 
population of our island, remains of potteries may be 
mentioned, which have been discovered at Hawcaster Rigg, 
above-mentioned as a place situated on a line of Roman road. 
Traces of another manufacture of a less creditable character 
have been found in some abundance at a place called Ling- 
well Gate, in the parish of Rothwell, near Wakefield. You 
possess an example of this manufacture in your own museum, 
which I have the satisfaction of exhibiting to you. It is 
part of a mould for casting Roman coins, objects which have 
been found in several localities in Roman Britain. The
