EAST YORKSHIRE ESKERS. 
Under * S. and S.E. Yorkshire/ Prof. Gregory, in his paper 
on ‘ The English Eskers * ( Geol . Mag., 1922, pp. 30-34), says 
‘ E. and S.E. Yorkshire — An “ esker-like ■’ ridge resting on 
the Upper Boulder Clay in Stanghow Moor, Eskdale, occurs 
on the flanks of the Cleveland Hills. Better developed eskers 
have been described in Holderness (J. Philips, Mem. Geo. 
Survey). The best known example is at Brandesburton, east 
of Beverley, and outside of Carvill Lewis’ line of E. Yorks, 
terminal moraine. It contains marine shells. The course 
and form of this ridge is well shown on the 6" map. It is about 
2 miles long, and includes Barf Hill, Coneygarth Hill, and 
Gildholm Hill. I have not visited* it, but its position suggests 
its origin as a Kame marginal to the North Sea ice. A more 
detailed account of this formation is desirable/ For this area, 
then, Prof. Gregory relies upon the geological map, and upon 
‘ Phillips 5 (who died in 1874) ; upon the Geological Survey 
Memoir, published in 1885. Of the whole army of workers 
who have described these gravels- — Carvill Lewis, Fox-Strang- 
ways, Kendall, Lamplugh, Stather, Sheppard and others, 
whose memoirs and papers are carefully indexed in the Biblio- 
graphy of Yorkshire Geology, published in 1915 (from which 
Prof. Gregory, in other instances, quotes, so presumably has 
consulted), not a word is said ! The remarkable evidences 
produced by the sections made in the far finer Holderness 
Hills at Burstwick and Kelsey Hill, Keyingham, and the 
enormous amount of evidence they produce as to their morainic 
origin, are not even referred to. All we are told is that the 
Professor ‘ has not visited ’ the area. He also has evidently 
not consulted the somewhat extensive literature of the last 
quarter of a century, yet we are asked to accept his generali- 
sations, and, to crown all, we are calmly told that ‘ a more 
detailed account of their formation is desirable/ East York- 
shire, in the past, has provided so many pit-falls for those who 
attempt to unravel its history by studying old maps — not 
themselves always reliable — that we should have thought 
Professor’ Gregory, competent geologist that he is, would at 
least have taken the trouble to have visited our area, instead of 
sitting in his chair at Glasgow and telling East Yorkshire 
Geologists what he thinks is the interpretation of features 
shown on maps.
