sloping ones. The bases, too, in some cases, have been undercut, 

 and around the basal edges of some of the fine grits a series of 

 vermiculate grooves is present. 



With regard to the chert, this invariably occurs in rectangular 

 blocks, the whole surface usually exhibiting a dull polish. Where 

 fossils are present. (Crinoid stems usually), these have been etched 

 out, leaving the surface full of small holes. 



A few of the stones, the andesites especially, are remarkable 

 from the fact that the sand-blast appears to have encountered a 

 joint or crack in the stone and this has been enlarged and cut down 

 considerably, giving the stone the appearance of having been cut by 

 a blunt saw. 



It would be quite impossible to describe the various modifica- 

 tions seen in the different pebbles from the Pendleton section. A 

 selection, therefore, has been made of the more striking examples in 

 this prolific series, and these are figured on the accompanying plates 

 (Figs. 1-14). 



Since .my Pendleton discovery I have found two other localities 

 near Manchester which have yielded facetted and wind-worn pebbles. 

 One is on Kersal Moor, about ij miles N.E. of the Pendleton site, 

 and on the other side of the Irwell valley. The surface of the ground 

 is here dotted over with similar moraine-like hills of Glacial sand and 

 gravel, and on the S.W. slope of one of these — Sand Hill, altitude 

 250 feet above O.D. — I succeeded in finding about half a-dozen 

 distinctly facetted Drift pebbles. Their occurrence here is an exact 

 parallel to Pendleton, both as to position and from the fact that the 

 pebbles which exhibit wind action have also been split or fractured. 

 One specimen of fine grit was found in situ about 18 inches below 

 the present disturbed surface — i.e. about 9 inches deep in the sands. 

 The top-soil consists of about 9 inches of densely matted rootlets of 

 grass mixed with dark sand, which contains, amongst other things, 

 numerous chippings of flint and chert. Other facetted pebbles were 

 found in the sand where the top-soil had been removed. 



The presence of a Neolithic floor at this site was first brought to 

 public notice in 1908 by the late Mr. C. Roeder, of Manchester, who 

 found large quantities of flint cores, flakes, and scrapers, haematite, 

 etc., also a stone spindle whorl, all obtained from the top-soil. 1 



A similar Neolithic floor is present on an adjacent hill known 

 as Rainsough on which a " camp " is marked on the Ordnance maps. 

 I have here met with identical flint and chert cores and flakes in 

 the top-soil, but was unable to find any facetted pebbles owing 

 to the dearth of suitable sections. 



Compared with coastal sites, the shallowness of the soil above 

 these Neolithic floors in these inland localities is a noteworthy feature. 



The other site near Manchester lies about a mile south of the 

 Pendleton locality, at Bolton Lodge sand quarry, off Eccles New 

 Road, Weaste. Several wind-worn Drift pebbles were picked up 

 here from the turned-up soil of an allotment overlying a small thick- 

 ness of Boulder-clay, resting on Upper Mottled Sandstone. The site
