The Glacial Geology of Northumberland. 



By J. A. Smythe, Ph.D., D.Sc, Armstrong College, 

 Newcastle-on-Tyne. 



Introduction and References. 



Much has been written about the glacial geology of 

 Northumberland, but the information is of a localised kind 

 which precludes the formation of broad views on the subject. 

 The present paper (the material for which has been collected 

 in the author's spare time during the last five years) is an 

 attempt to remedy this defect by a consideration of the glacial 

 phenomena exhibited over the whole county. Special reference 

 is, however, made to that portion which is bounded on the 

 north by the Tweed Valley, on the west by the Redewater and 

 North Tyne, on the south by the Tyne Valley, and on the 

 east by the sea, for it is in this tract that the most interesting 

 and complex phenomena are met with. The author's in- 

 debtedness to other workers in this field is acknowledged in 

 the text, references to the publications in the following list 

 being given by the numbers in square brackets. The list is 

 not intended to be exhaustive, but it may be taken to contain 

 most, if not all, of the important papers on the subject ; the 

 arrangement is chronological.
