that it was found at 68 feet from the surface, which is a few 
feet higher than Coronation Street, and was perforated at a 
depth of 132 feet, so that, allowing for dip, the marl is at this 
point about 60 feet thick. Near the bottom of the shaft the 
marl is fossiliferous, and contains bands of stone and cavities 
containing crystals. The prevailing colour is a rich dark 
chocolate or brown, with occasional mottlings of green and 
white. One of the green bands distinctly shows a small 
reversed fault, having a throw of 10 inches, which is worthy 
of note, as the hade is to the S.S.E., agreeing in direction and 
amount with that of several fissures filled with Marl, which 
are to be observed in other sandy beds further to the N.N.W. 
It may be remarked in passing that the statement is made 
in at least one modern Geological Text-book that all. faults

One of the hard bands in the marl is of great interest. 
The lower part consists of about 10 inches of false bedded 
sandstone, capped by a thin seam of highly ferruginous 
marl, containing myiiads of fossil shells, most of which are 
small, many being microscopic. The following species have 
been identified : Serpula pusilla, Bakevellia antiqua, Cardio- 
morpha modioliforrnis, Rissoa, Loxonema, &c. 
A hard calcareous band of about three inches thick lies 
four feet above the last bed, and fossils are thickly scattered 
through the stone. 
The soft marl in the vicinity of these bands is also 
fossiliferous, and geodes containing crystals of calcite are 
numerous. The following species occurring in the hard 
band have been determined : — Schizodus obscurus, Schizodus 
Schlotheimi, and Bakevellia antiqua. Some of the species 
are identical with those found at Collyhurst, and the beds 
are probably of the same age. 
About six feet of marl lie above the last hard band, and 
the Permian beds in tliis shaft are capped by two feet of 
sand and 10 feet of glacial clay without pebbles, and partaking
