OBJECTS. 
This Society was founded in the year 1837 at a meeting of coal pro- 
prietors of the West Riding at Wakelield, and for nearly forty years its 
operations were conKned to that Riding. The purposes for which it was 
formed were the investigation of the Yorkshire Coalfield and the gathering 
of such definite information about its seams of coal and ironstone as would 
be of use in the prosecution of mining operations. The scope of the Society 
was soon enlarged to include the Arts of Mining and Metallurgy and 
their dependent manufactures, and of the machinery' and tools employed 
therein, and the name was correspondingly expanded to " Geological and 
Polytechnic." The subscription was originally half-aguinea, but when 
Proceedings were published half-a-crown extra was added to meet the cost. 
In 1838 the work of establishing a Museum Avas commenced, and in 1839 the 
preparation of a section across the Pennine Chain was undertaken. Meetings 
were held regularly at which papers on geology, paheontology, mining, and 
kindred topics were read and discussed. In 1877 the rules were revised, and 
it was decided to extend the Society's operations from the West Riding to 
the whole county. In addition to the ordinary meetings of the Society, from 
time to time investigations were undertaken by the aid of funds specially 
raised. Among these were the investigation of the bone-bearing deposits of 
Raygill, the pre historic mounds of Grassington, the source of the Aire at 
Malham, and the Underground Waters of Ingleborough. In the two latter 
the Society worked in conjunction Avith a Comnjittee of the British Associa- 
tion. At the Annual Meeting in 1906 it was resolved to change the title to 
"The Yorkshire Geological Society."
