Ir is now 8 years since I commenced observations upon the 
Glacial phenomena of the Cleveland area—using the term in its 
broadest sense as including the whole of the Jurassic mass of 
North-eastern Yorkshire, but no results were attained in the first 
5 years. The investigation, however, of a tract of country on the 
western edge of the Vale of York familiarized me with many 
of the more patent signs of old glacier-lakes, especially the pheno- 
mena of abandoned overflows, and this experience enabled me to 
recognize the great Newton-Dale valley as belonging to this 
category. Following this clue backward, I discovered the great 
system of lakes and related phenomena now to be described. 
The progress of the investigation of the area west of the Ouse 
has been briefly recorded in papers submitted to the British Asso- 
ciation,’ and on various occasions has been communicated to the 
Yorkshire Geological & Polytechnic Society.” A new stimulus to 
these studies was given by Prof. W. M. Davis, who accompanied me
