with experienced local workers, including Mr. Walter Hemingway, 
of Barnsley, and Messrs. H. H. Corbett and H. Culpin, of Don-

debted for much valuable criticism and helpful advice. 
I. — The GLACL4.L Deposits. 
(1) Staincross. 
Professor Green describes a section in a railway cutting 
at Staincross,* about two miles north of Barnsley, showing 
forty feet of stiff boulder-clay, filling up a hollow excavated in 
the WooUey Edge Rock of the Middle Coal Measure series. The 
surface of the sandstone at the face of junction he found to 
be much shattered and smashed, large blocks of sandstone being 
wrenched off and imbedded in the clay. The clay was divisible 
into two beds (PI. LIV.). The lower contained large quantities 
of Coal Measure rocks, chiefly sandstones, with fragments of 
well-scratched shale and pieces of coal. Foreign rocks were also 
found, including Carboniferous Limestone (ice-scratched), chert 
and black earthy limestone, and a piece of blue closely-grained 
trap, with crystals of iron pyrites. Overlying this lower clay 
and sometimes dovetailing into it, were seams of warp, bluish- 
brown in colour, finely laminated, but with wavy and irregular 
bedding, and containing well-rounded pebbles of Carboniferous 
sandstone and bits of coal. Over these comes an upper clay, 
more sandy in texture, with lenticular sheets of sand and gravel, 
and irregular interbedded masses of warp, rudely bedded, and 
in places sharply contorted. This clay is traversed by cracks 
with polished faces filled in with sand. 
(2) Royston aiid Carlton. 
This boulder-clay appears to extend E. and X.E. to Carlton 
and Royston (Fig. 4), and the whole country for some square 
miles is strewn with glacial relics. f The geological surveyors 
have recorded a large boulder of shap granite at Royston J 
(Plate LV.) and a boulder of syenite at Notton Green (170 feet
