here to-day, in this most central town of the South Yorkshire 
district, may result in a deep and wide-spread feeling of 
fellowship and good will, and that a great accession to the 
list of our members, may show that the public and scientific 
interest of the West Riding, is being actively and effectively 
exerted, in sustaining the growth, and promoting the influ-

ox A SECTION OF BOULDER CLAY, NEAR BARNSLEY. BY A. H. 
GREEN, M.A., F.G.S., PROFESSOR OF GEOLOGY IN THE 
YORKSHIRE COLLEGE OF SCIENCE, LEEDS. (PLATE VIL) 
It is very well known that the distribution of drift, on 
opposite sides of the southern portion of the Pennine range 
of hills, is very unequal. While all the low-lying grounds of 
Lancashire and ISTorth Staffordshire, are thickly covered by 
broad sheets of Boulder Clay, Sand, and Gravel, the correspond- 
ing tract of the Yorkshire and Derbyshire Coal-field is all 
but a driftless area. Drift, however, is not altogether absent 
from the plains east of the Pennine ridge, and of the scattered 
patches which have been detected here and there in this 
district; one of the most remarkable is the deposit which it is 
the object of this paper to describe. It was laid open in the 
cutting of a mineral railway near the Carlton Lane Toll- 
gate on the Barnsley and Wakefield road, about two miles 
north of Barnsley, and the section of that part of the cutting 
in which the drift bed occurs is shown in Plate YII. 
On the south, the section traverses the Woolley Edge Pock 
and the underlying Woodmoor Coal, and we soon reach the
