direction of the col. By this valley at 335 feet the Elsecar lake would be dis- 
charged into a smaller lake held up by the ice in the Wentworth Woodhouse 
Valley. When the ice laid down the Masbrough and Sitwell Vale patches of drift, 
the Rother Valley would be blocked, and the glacial drainage would be discharged 
round the lobe of ice by channels at Greasborough and Sitwell Vale at 275 feet, 
and thence into the Don by the Hooton Roberts Valley (180 feet). <A slight 
forward movement of the ice to the gravel patches east of Hooton Roberts would 
close that valley and cause the drainage to discharge by a col on Conisborough 
Parks at 260 feet. 
The second glacier does not seem to have advanced far beyond the curved line 
stretching from Barnsley through Adwick-on-Dearne to Conisborough. This, by 
damming the Dearne at Ardsley, would re-form the Barnsley lake, discharging 
over the Stairfoot col at 175 feet. This drainage would then escape by a narrow 
notch between Adwick-on-Dearne and Swinton into the Don at Mexborough. 
A further advance would bring the Wombwell-Swinton Valleys into use as 
overflows, and the Hooton Roberts Valley would be the route into the Don. The 
damming of the Dearne at Barnsley by a lobe of ice would bring into use a couple 
of small valleys at Barnsley as overflow channels. The gradual advance of the 
ice across the Conisborough gorge would cause the blocking of the Don, with the 
formation of a constantly enlarging lake, which would overflow first by the Hooton 
Roberts Valley (180 feet), and then by a series of cuts through the 275-foot 
contour on Conisborough Parks, first draining into the Don behind Castle Hill, then, 
as the Warmsworth watershed was reached by the ice, into the Balby Valley, and, 
pen this was closed by the ice, over the low watershed into the Loversall 
alley. 
The further advance of the ice-front to Edlington caused a shallow cut to be 
made through the 300-foot contour, discharging into the Loversall Valley and 
thence into the Trent. This channel, which bends round in a semicircle, became 
the permanent course of the Wadsworth drainage on the retreat of the ice, the 
old channel at Balby having been filled up with till. When the ice rose above the 
330-foot contour the gorge of the Don was entirely closed, and the drainage of 
the great lake, reaching from Bretton Park and Cawthorne, north of Barnsley, to 
Clay Cross and Heath, south of Chesterfield, would all be discharged by the 
Kiveton gorge into the river Ryton. 
This explanation may be thought to rest too largely on suggestions, but where 
the evidence is so scattered and imperfect it is difficult to see how this can be 
avoided if any explanation is to be attempted. 
3. The Discovery of Human Remains under Stalagmite in Gough’s Cave, 
Cheddar, Somerset. By Henry N. Daviss. 
The cave is an ancient subterranean waterway in the Carboniferous limestone 
rocks of the Cheddar Gorge. It has many branches, but we have only to deal with 
a small fissure on the north side. Excavations have been in progress for twelve 
years, and the following accumulations have been cleared out :— 
(a) Recent accumulations, which filled the entrance and covered the upper 
stalagmitic crust. 
(6) A calcareous bed, consisting of thin layers of friable stalagmite from 
4 inches to 12 inches in thickness, 
(c) A bed of cave earth, 4 feet to 6 feet in depth, in parts rubbly and stratified, 
and containing large blocks of limestone which have fallen from the roof. 
(a) A lower bed of hard crystalline stalagmite, which has underneath it, here 
and there, beds of sand and pebbles. 
These successive deposits pass without a break into thesmall fissure on the north 
previously mentioned. While the contents were being removed from this fissure 
the skull and other bones of the human skeleton were discovered. Some were 
removed, others left in sidw, and so the exact position of the body remains fixed
