All the above sections show that the lower gravel and 
sand is a very variable deposit. CJp to the present time, to 
my knowledge, no organic remains have been found in it, 
and the rocks met with have not been so carefully examined 
to speak with certainty as to whether or not they are of 
the same description as those found in the till and upper 
gravels. It may be the remains of a much greater deposit, 
which has been denuded before the formation of the till. 
Lip to this, so far as I know, no scored or striated pebbles 
have been observed, although there are plenty of well 
rounded rocks in it. 
Whenever any excavations are being made through the 
till it is desirable that parties present should carefully ex- 
amine the sands and gravels lying under it as well as the 
broken rock so often met with on the upper portions of 
Triassic, Permian, and Carboniferous beds found near Man- 
chester. 
The classification of the drift in this district may still be 
conveniently divided into, in the descending order: — 1. 
Valley sands and gravels. 2. Beds of sand and gravel con- 
taining layers of clay and till. 3. Thick bed of till con- 
taining beds of sand and gravel. 4, Lower sands and gravels.
