The President said he wished to make a few remarks on 
the Lancashire and Cheshire Drift. In the year 1841 he first 
attempted to class the drift deposits found in the neighbour- 
hood of Manchester, in a small Paper with a map, which he 
prepared for the Statistical Society of Manchester. In that 
Memoir he divided the foreign drift in the ascending order : 
(1) lower sand and gravel; (2) till; (3) upper sand and 
gravel; and he described the more modern deposits found in 
valleys; (No. 4) as valley gravel. This order he adopted in 
a Paper read before the Manchester Geological Society on 
the 22nd December, 1842 — “ Notes on the Lancashire and Che- 
shire Drift,” — and printed by that Society in their proceedings 
of 1843. In that Paper, in treating of the upper beds of 
sand and gravel, he says — “ At Manchester, it (the Higher 
Drift) is composed of lower gravel, till, and sand and gravel, 
while at Heywood and Povnton, near the base of the Pennine 
chain, the beds of sand and gravel are parted by several beds 
of loam and clay.” Again, in speaking of No. 3 deposit, he 
says — “ Tl^g gently rising lands of the two counties arc 
generally composed of this deposit. It varies much both in 
its composition and thickness. Near the sea at Ormskirk, 
the till is sometimes found without it; but as you proceed to 
the East it makes its appearance, and gradually thickens 
until it attains its greatest thickness near the base of the 
Pennine chain: not only does it increase in thickness, but it 
becomes more complex, and contains beds of clay, marl, and 
loam of several yards in thickness. The country lying 
between Manchester, Bolton, Bury, Rochdale, Ashton, and 
Stockport, for the most part is upon it, and forms one great 
sand bank, which continues South into Cheshire.” The 
-I* 
same classification he adopted in two Papers, one on the 
Drift of Manchester, and the other on the same deposits at 
Blackpool, printed in Yols. VIII. and X. of the Society’s 
Memoirs, as well as in a Paper printed in the Manchester • 
Geological Society’s Transactions for June, 18G2.
