 All the above sections show that the lower gravel and 

 sand is a very variable deposit. Up to the present time, to 

 my knowledge, no organic remains have been found in it, 

 and the I'ocks 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. 

 Up 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 gi'avels.
