table-like forms. These beds are doubtless the representatives of those 
which, a few miles eastward, produce the Roche Percée.

the following section occurs :—

The beds appear to be perfectly horizontal. Those of sand and 
arenaceous clay, though having the appearance of well characterized 
layers at a little distance, and giving the banks aribboned aspect, are 
found, on closer examination, to pass almost imperceptibly into each 
other. This peculiarity is often to be observed in almost all localities 
where these rocks are found. The so-called ‘ leaf-beds”’ are of a greyish- 
purple tint, and contain many impresssions of flag-like parallel-veined 
leaves, which, though distinct enough when freshly taken from the bank, 
it is impossible to preserve on account of the crumbling nature of the 
matrix. The ironstone, though generally forming extensive sheets, is 
nodular in structure, and varies a good deal in thickness. It weathers a 
bright brownish-red, is hard, compact, and very heavy, and on fresh frac- 
ture is bluish to yellowish-grey. 
210. A short distance south of this locality, the bank shows the fol- 
lowing section very perfectly :—(Plate 3, Fig. 2.)
