ON THE EEGENT EXTENSION OF MINING OPEEATIONS UNDER 
THE PERMIAN FORMATIONS. BY THOS. WM. TEW, ESQ., J.P.

town of Pontefract. You met here on Thursday, the 4th November, 
1869, under the presidency of Lord Houg-hton, and thirteen years

find that during this interval of time, industry, energy and capital

been accomplished by this practical application of geological science 
since they last honoured Pontefract with a visit.

and yourselves, for the compliment you have conferred upon me, 
in requesting me to act as your Local President on this occasion. 
I ask your considerate forbearance and co-operation in undertaking

of my earnest wishes to prcjmote the interests of this valuable 
Listitution, with which it has been my privilege to be associated 
for upwards of twenty years. 
After the exhaustive addresses of your past Presidents, the 
devoted attention to special subjects of the scientific members of 
this Institution, and the published papers in its transactions, it is 
difficult for an amateur Geologist, like myself, to discourse on a 
special subject ; but Avith your permission, I will venture to make
