60 TATE: THE YORKSHIRE BOULDER COMMITTEE. 
into the Cragg Brook valley to Mytholmroyd; while the more 
southern portion, after being pushed to the north by the Green 
Withens (1400’), has crossed the watershed along Blackstone Edge, 
descending the Ryburn valley to Sowerby, North Dean, and Elland. 
If this be so, systematic exploration of the country extending from 
Littleborough to Blackstone Edge, and of the high ground lying” 
between the foot of Turley Hole Edge and Ripponden should 
reward the explorers with evidence thereof, and we earnestly com- 
mend this bit of research to the band of active workers already 
familiar with the various. kinds of pebbles likely to be found. 
Turning to South Yorkshire, Mr. Hemingway has contributed 
another batch of the ‘finds’ peculiar to the Dearne Valley (see 
Report for 1894). These rocks are quite unlike the pebbles 
obtained from boulder clay in close proximity (Carlton, East Gawber, 
Smithy Green), and two or three may be Norwegian. The writer 
accompanied Mr. Hemingway in a careful examination of the area 
to which these boulders are restricted, but he is unable to explain 
their presence there, unless it be that they were brought from the 
coast in connection with the making of the Barnsley Canal, which 
was navigable in 1799, the Act of Parliament having been passed 
in 1793. 
During our annual meeting held in Doncaster, October 1894, 
Mr. Corbett first brought under notice of this Committee several 
remarkable exposures of boulder clay in that district. These have 
been investigated by our Chairman, under the guidance of 
Mr. Corbett, and their extremely valuable joint report thereon will 
be found herewith. 
Lastly, coming to the coast, the Hull Geological Society’s East 
Riding Boulder Committee have completed their elaborate explora- 
tion of Holderness, adding 2,600 boulders to those previously 
recorded. In the method and thoroughness of this work our Hull 
friends have set an example of which all British glacialists will do 
well to take note. 
The following reports received during the year have been 
accepted :— 
Reported by Mr. C. T. THORNTON Comugr, L.R.C.P., M.R.C.S., Pickering: 
South of Pickering there is a line of conglomerate composed of 
perfectly rounded stones about twelve or eighteen inches in diameter, 
bound together by a small amount of clay ; they are evidently water- 
worn. I saw them recently exposed during drainage operations 
along the south side of Vivis Lane (alt. roo ft.) North of Pickering 
there is said to be a line of boulder clay and debris running east and =]
