It will be seen that the boulder clay and sands were 82 
feet thick at the Levenshulme Printworks, and that the 
new red sandstones continued to a depth of 450 feet, when 
water was met with (of excellent quality) in the pebble beds. 
Half a mile further eastwards, near Sandfold, some borings 
were taken with a view to the erection of Sir Joseph Whit- 
worth’s works on that site ; but although no accurate record 
was kept, I have learned that clay and sand were found to 
a great depth, so that no solid foundation for steam hammers 
could be obtained : — thus showing that a similar depth of 
clay probably prevails over a considerable area. At Sand- 
fold the upper clays come upon the section, the sands being 
largely developed there between the upper and the lower 
clays, and producing much water. It is interesting to note 
that a Roman cinerary urn was found at Sandfold, a portion 
of which is in Mrs. Aitken’s possession. 
The section therefore commences on the west with New 
Red sandstone at Withington, and terminates westward in 
the same. The fault at Slade Lane brings the Levenshulme 
limestone nearly to the surface with (probably) the new red 
sandstone in front of it eastwards, and the Permian mea- 
sures westwards, dipping under the Trias at Withington. 
The great fault which brings up the Levenshulme lime- 
stone is shown in Mr. Binney’s diagram of the section from 
Heaton Mersey to Goyt Hall beyond Stockport, and appears 
to be the great boundary fault of the Manchester coal field, 
which is seen at Collyhurst and Heaton Norris. At the 
latter point it is marked on the Ordnance Survey as being a 
downthrow to the east of 200 yards, but at Slade Lane it 
would appear to be rather an upthrow fault to the west. 
It is quite clear that the recent discoveries at Withington 
and Levenshnlme will necessitate a careful resurvey of the 
district, as the present maps do not show correctly the lines 
of faults, nor the areas covered by the Permians, as recently 
brought to light. A considerable quantity of large blocks
