They show marked current bedding, and contain thick pockets of 

 clay, and thin streaks of coal fragments. In places they are slightly 

 faulted. They vary in texture from fine running sands to gravelly 

 deposits. 



These sands cover the north of Manchester from Boggart Hole 

 Clough in the east to Prestwich in the west, and are continued across 

 the Irwell over North Pendleton and Irlams towards Eccles. 



The horizontal distribution of the post-Glacial and Glacial de- 

 posits as shown by recent information, therefore, agrees with Binney's 

 map, except that the extension of the river deposits in the Stretford 

 area has now been shown to be greater than was there indicated. 



The Vertical Sequence of the Drift Deposits 



There is considerably more information concerning the vertical 

 sequence of the Drift than was available when Binney and Hull 

 discussed the subject. 



In the Manchester area all the bore-holes and cuttings south of 

 a line from Newton Heath to Pendleton show that the Glacial deposits, 

 where they have not been eroded by the rivers, consist almost 

 entirely of Boulder-clay. In the south and north of this area sandy 

 bands of considerable thickness are found to occur within the clays. 

 These bands, however, are all lenticular and inconstant, as shown by 

 the following examples. 



In the Fallowfield district the sewer laid along the Wilmslow 

 Road shows great variability of superficial deposits. This is clearly 

 seen in the section (Fig. 1, PI. III.). Between Ladybarn Road and Mon- 

 mouth Street there is a sand-bed which at Ladybarn Road is 11 feet 

 thick, at Old Hall Lane more than 27 feet thick, and at Monmouth 

 Street 9 feet in thickness. 



In the northern part of the Boulder-clay district a bore-hole put 

 down by the Clayton Aniline Company shows clay with sandy bands. 

 Roeder gives a section of a sand-pit in this vicinity, behind Clayton 

 Hall. The record is incomplete, as the only mention is of a 7-foot 

 sand-bed. In the 6-inch Ordnance Survey map published in 1847 

 two sand-pits are marked in this district ; one near the Ashton New 

 Road end of Schofield Street, about 200 yards from the site of the 

 present brick works, and the other about 100 yards north of Alder- 

 dale House, and the same distance east of Edge Lane. 



In a bore-hole at the Pott Street Hydraulic Power Station 80 

 feet of Boulder-clay with " sandy bands " was proved. 



In the Newton Heath area the deposits are very variable, some 

 showing clay only, others clay with sandy bands, while the bore-hole 

 at Newton Heath Brewery has a 30-foot sand-bed, 19 feet from the 

 bottom of the Drift, and that of the Heath Brewery proved 25 feet of 

 quicksand, 50 feet from the base of the Drift. 



Farther to the east, in Jericho Clough, Clayton Bridge, a bore- 

 hole recorded by Binney shows two sand-beds, the thicker being 

 12 feet.
