across the valley near the Brick and Tile Works, showing 

 the position of the patch of Till and the bottom of the valley, 

 above 820 feet in depth, which is a watershed on a flat more 

 than a mile in length, free from Till, so far as our observa- 

 tion went, the greater part of the water flowing to the 

 German Ocean, but some little finding its way down to the 

 Irish Sea. That Till did once occupy the bed of this valley 

 near the Brick and Tile Works is pretty certain, or else the 

 deposit on the sheltered hill side would scarcely now remain 

 to tell its tale. 



There can be little doubt of the valley of Todmorden, at 

 least that pai-t of it at the summit is an ancient one, formed 

 long anterior to the period when the Till was deposited, and 

 that the latter once occupied it and was afterward swept 

 out on the rising of the land, as is probable from the small 

 patch left near to the Brick and Tile Works. 



Concluding Remarks. 



From the sections of drift given in this communication it 

 is clear that these deposits lie on a very irregular surface of 

 underlying carboniferous and triassic rocks, for, while we 

 find little or no drift on strata only 205 feet above the sea 

 level at Eainhill; at Tandle Hill, near Three Gates, above 

 35 miles to the north-west, we find 510 feet of drift on Coal 

 Measures at an elevation of 233 feet ; and, again, 12 feet of 

 that deposit at an elevation of 650 feet near the Kochdale 

 Brick and Tile Works at Summit. 



How it is that the drift does not reach to so great an 

 elevation at the southern entrance of the Todmorden valley 

 as it does at the places 1,300 or 1,400 feet high, shown in 

 the first part of these notes, is difficult to account for, with- 

 out we suppose that the land in the former case has not 

 been raised so much as in the latter since the deposition of 

 the drift, or, what is more probable, that the latter has 

 been removed since,
