These two boulder clays are placed according to the 
classification of the Geological Survey, but although it is 
very convenient to have an upper and a lower boulder clay 
and pack in all the sands and gravels between them, it 
cannot be done, for there are at places 3 or 4 boulder clays 
divided by sands and gravels. Certainly only two are to be 
found here ; but there are two series of sands and gravels, 
the higher one being above the upper boulder clay. In this 
section probably the cemetery beds are represented by the 
higher sands and gravels. 
None of the sections hereinbefore described, except that 
at Bakstondale, are actually seen down to the underlying 
rock, but it is probable that they will all be found to be similar 
in that respect when excavated to a sufficient depth. 
The gravel beds described in this communication have, 
doubtless, been formed under nearly similar conditions, but 
at different times to those at Macclesfield. However, we are 
still at a loss for a theory which will satisfactorily account for 
all the drift phenomena found between these higher levels > 
and the 50 miles of country intervening betwixt them and 
the sea, of which the North Cheshire Brewery beds at 
Macclesfield afford a comparatively simple section.
