side the county for the purpose of stud3dng areas and rocks 

 which have furnished boulders to the Yorkshire drift. Further, 

 a number of prominent geologists within and without the county 

 and not on the Committee, have been called into willing service. 

 Many members of the Geological Survey have given valuable 

 assistance, including Messrs. A. H. Green, J. G. Goodchild, 

 J. R. Dakyns, R. H. Tiddeman, T. McKenny Hughes, C. Fox- 

 Strangways, G. W. Lamplugh, E. H. Cunningham-Craig, and 

 H. Brantwood Muff. 



Distinguished Petrologists have also been requisitioned, 

 including Messrs. J. J. H. Teall. Alfred Harker, Professor 

 Brogger, of Christiania, and Dr. Munthe, of Upsala. These 

 have all rendered invaluable help in examining and identifying 

 certain rocks for the Committee. 



The Chairman of the Committee (Professor Kendall) made 

 a special visit to Southern Norway, and brought back rock 

 specimens and information which have been of immense 

 service and interest to the workers. 



No account of the Boulder Committee can do justice to 

 the subject which does not specially recognise the services of 

 Professor Percy Fry Kendall. The researches had been 

 steadily pursued for some years, a great number of records 

 made, and much preliminary work done. But the advent 

 of Professor Kendall gave aUke a great impetus and a 

 new interest to the task. Since 1896 he has been Chairman, 

 and the life and soul of the Committee. He has inspired 

 the members with enthusiasm, directed their efforts, checked 

 their records, furnished numberless records himself, and 

 interpreted results by his own illuminating comments and 

 discoveries. 



An acknowledgement must also be cordially made to the 

 Council of the Yorkshire Geological Society, who have on several 

 occasions arranged their own excursions with the express object 

 of furthering the work of the Boulder Committee. The Society 

 made excursions to the English Lake District, the Cheviots, 

 and to South Scotland, which the Yorkshire NaturaUsts' 

 Union could not well have undertaken. 



The invasion of foreign ice has always made our East 

 Coast the centre of interest for boulder distribution. Every 

 searcher has looked upon the sea coast as a sort of glacial 

 Mecca, to which he must make as many pilgrimages as possible, 

 and the inland investigator has regarded with envy the East
