336 Y.N.U. IN EDLINGTON AND WADWORTH WOODS. 
the Upper and Lower Magnesian Limestone and the Middle Marl 
was passed through and examined in the railway cutting at 
Warmsworth. This is probably one of the finest existing sections of 
the Yorkshire Permian Rocks. 
On arriving at Mexborough the party, eighteen in number, 
proceeded to the Denaby Main Colliery, where they were received 
with great kindness by Mr. Chambers, who deputed Mr. Witty, one of 
his staff, to take them down the shaft. Amongst other objects of 
interest in the colliery, a wall was pointed out which separates the 
working part of the colliery from a portion which has been on 
fire for some twelve years. The new apparatus for washing coal was 
shown and explained to the party ; though somewhat complicated in 
detail, the apparatus is fairly simple in principle, and appears to do its 
work satisfactorily. © 
After leaving Denaby, the geologists walked to Conisborough 
Station. On the way the effect of a strike fault in altering the 
outcrop of the Permian Rocks was pointed out. Close to 
Conisborough Station a section of Carboniferous Rocks capped 
by drift was examined. 
A visit was afterwards paid to the new shaft now being sunk at 
Cadeby. <A section of the rocks already passed through was 
explained ; it is stated that at this point there is a boulder clay 
containing well-scratched boulders of Glacial origin and having 
a depth of 60 yards. This is of interest owing to the comparative 
scarcity of glacial deposits in the Doncaster district. In a quarry at 
the back of the colliery, there is a good section of the Lower 
Magnesian Limestone showing a small natural cave and some 
evidence of dislocation. Photographs of this section were taken 
by Mr. M. H. Stiles. The limestone contained numerous small 
specimens of Axinus (Schyzodus) obscurus whilst numerous ferns, 
calamites, etc. (genera and species not determined), were found 
in the Carboniferous Shale. Before the party returned to 
gious thanks were formally stators to Messrs. Chambers 
and Witty.
