2 Jackson, Facetted Pebbles with Glacial Deposits. 



The Manchester Museum also possesses a series of pebbles 

 (mainly quartzite) worn by natural sand-blast, which were obtained 

 from Drift overlying Bunter Sandstone, near Ramsdale Ho., Notts, 

 by Mr. H. S. Holden. 



A further interesting record is that of Mr. L. J. Wills, who refers 

 to the occurrence of wind-worn pebbles in high-level gravel, near 

 Bromsgrove, Worcestershire. 1 Here they formed a prominent 

 feature of a deposit overlying Lower Keuper Sandstone, at about 

 350 feet above sea-level. This fact is of interest in connection with 

 the Pendleton series described in the present paper. 



Two other interesting occurrences are cited in the discussion of 

 a paper on " The Keuper Marls around Charnwood," by Mr. T. 0. 

 Bosworth. 2 Dr. C. A. Matley there states that " he had found dreik- 

 anters as surface specimens in the marl country near Birmingham." 

 Mr. E. E. L. Dixon also refers to dreikanters which he had picked 

 up on the surface near Lichfield, where they appeared to be numer- 

 ous. Though he had originally thought that they might have been 

 derived from adjacent Triassic outcrops, either directly or by way of 

 Glacial Drift, he was prepared, after discussion, to accept the view 

 that they were chiselled during a dry epoch of the Pleistocene. 3 



A selection of some of the wind-etched pebbles dealt with in sub- 

 sequent pages was exhibited in 1916 before the Geological Society 

 of London, 4 and later before this Society. 5 



For the convenience of description it will be advisable to divide 

 this communication into two parts : 



1. The Distribution of Facetted Drift Pebbles in the Manchester 

 and Wirral Districts. 



2. The Geological Horizon and Significance of the Facetted 

 Pebbles.

During the construction of new roads for building extensions in 

 the higher parts of Pendleton, Lancashire, the western side of a 

 moraine-like hill has been cut into, exposing an excellent section of 

 current -bedded and faulted Glacial sands and gravel. The position 

 of the site, known as the Claremont Sand Pits, is : Lat. 53 29' 52" ; 

 Long. 2° 18' 43" W. It is situated on the west side of^Claremont 

 Road, 6 about a third of a mile south of Irlams o' th' Height ; the 

 altitude is between 200' and 225' O.D. 



This hill, which overlooks the lower land to the S.W., W. and 

 N.W., forms part of a series of similar moraine-like hills, ranging 

 northwards, and bordering the valley of the River Irwell.
