THE YORKSHIRE BOULDER COMMITTEE 
AND ITS EIGHTH YEAR’S WORK. 
THOMAS TATE, F.GS., 
Leeds; Hon. Sec. to the Vorkshire Boulder Committee. 
Durinc the year special attention has been given by the Committee 
to the glacial geology of the hilly country around Barnsley, and they 
cordially recognise the valuable services of Mr. Hemingway, Old Mill 
Lane, Barnsley, but for whose labours, extending over several years, 
many evidences of ice-action in this district would have been irre- 
coverably lost. The extensive series of personally-collected speci- 
mens submitted by him for identification, along with the perforated - 
map accompanying his report, has materially aided the investigation, 
and lightened the work attempted by this Committee. 
A strip of comparatively high ground (200 ft. to 300 ft.) some 
eight square miles in extent, ranging from Notton and Notton Lane 
on the north, to the river Dearne at Old Mill and Burton Grange on 
the south, is, or has been, strewn over with Glacial relics ; and there 
are grounds for believing that two or three square miles lying south 
of this strip will have to be included before the work is completed. 
Much of the Coal shale hereabouts in weathering simulates 
boulder clay, and care is needed to connect this with the unaltered 
pebbleless, laminated shale below. A fine section of boulder clay 
and till, with intercalated lenticular patches of sand, about 4o ft. in 
thickness, is exposed near Staincross Station, and reappears in the 
railway siding of the East Gawber Colliery. Old gravel-pits in Lee 
Lane (250 ft.), and at Carlton Green (220 ft.), and the sewage farm at 
Burton Grange (140 ft.), together with almost every ploughed field 
or running stream within this area, have yielded detritus of the ice- 
sheet. Boulders or pebbles of rocks strange to the locality, having 
their angles ice-worn, their faces polished, and their surfaces scored 
with ice-scratches, have been found in plenty by those who cared to 
look for them. In Royston alone the Honorary Secretary observed 
on the road-sides, lying in farm-yards, or built into walls, boulders of 
quartz-felsite from Armboth Fell, quartz-porphyry from T hrelkeld 
in the Vale of St. John, diabase, basalt, andesitic ash, and volcanic 
breecia—all transported from a distance, in addition to a large 
erratic block of Shap Granite, previously recorded by Prof. A. H. 
Green, F.R.S. Mr. Hemingway’s collection contains boulders of 
Ennerdale_ granophyre, Borrowdale plumbago, rhyolite, rhyolitic 
Oct. 1894.
