Sheppard: The Yorkshire Boulder Committee s Work. 221 



addition to its membership of Mr. Percy F. Kendall, F.G.S. 

 The appearance of "Sir. Kendall into Yorkshire marked an 

 epoch in the history of the glacial geology of the county. 

 Mr. Kendall, as Secretary of the British Association Committee 

 of Erratic Blocks (appointed on the death of Dr. Crosskey) and 

 as Professor of Geology at the Yorkshire College, had excep- 

 tional opportunities for assisting the Committee in its work, and 

 of these he has availed himself to the utmost. In fact, the 

 greater part of the important records that have recently 

 appeared are certainly due, directly or indirectly, to Mr. 

 Kendall's influence. 



On Mr. Tate's death, another good petrologist, Mr. J. H. 

 Howarth, F.G.S., was elected Secretary, and Mr. Kendall the 

 President. In these capable hands the Committee's work is 

 now entrusted, and we hope it may long be so. During the 

 last five years the Committee's reports have bristled with 

 interesting items of information, some of the greatest possible 

 importance. Great strides have been made in tracing the path 

 taken by the ice-stream laden with Shap granite. In 1896 

 boulders of that rock were found in Lincolnshire, our neighbour- 

 ing county, for the first time. Important advances have also 

 been made in our knowledge of the distribution of Scandinavian 

 and Baltic boulders in this country. Many Lake District rocks 

 have been found in new situations ; chalk fossils, foreign to 

 the Yorkshire Chalk, have been found in the Holderness drift, 

 hundreds of coast boulders have been tabulated and classified 

 by Mr. J. W. Stather, F.G.S., with interesting results; many 

 varieties of Scandinavian and Cheviot rocks, common in the 

 clays of East Yorkshire, have been recognised in their original 

 homes. But to enumerate all the recent interesting ' finds ' 

 would mean another paper as long as this at least ! I trust, 

 however, that sufficient has been said to show that there are 

 indeed ' sermons in stones,' and that most important and interest- 

 ing facts relative to the movement of our ancient glaciers can 

 be adduced from an examination of the pebbles on the beach, 

 or the stones in the clay and gravel pits. 



I have had the advantage of seeing a proof of Mr. Sheppard's 

 paper on the work of the Yorkshire Boulder Committee. With 

 a modesty, natural under the circumstances, Mr. Sheppard says 

 little about the work of the East Riding Boulder Committee ; 

 but no retrospect can do justice to the facts, however, which
