CLARK : GLACIAL SECTIONS. 
succeed to the N.E. ; but here the sections were much more 
obscure. It seemed, however, pretty certain that they represent- 
ed two more folds of the same beds. 
Photo. IV is upon a line of rails crossing 1 the cellars from N.E. 
to S.W., and therefore about at right angles to the line of strike. 
Combining our various sections into one along its face they would 
give the actual appearance and probable connexion of the beds 
shown in Plate XXIII., Fig. 3. 
It will be noticed that S.W. of the central axis the beds are 
inclined the other way, or a second time against that bed. We 
need only call special attention to the layers of boulders, gravels, 
and sands, shown in Photo. VI. This bed was traceable quite 
across the area, the extreme sections in it being 100 yards apart. 
West of this come a few more boulder clays, after which the 
surface is occupied by post-glacial beds, as already said. In parts 
the two were hard to distinguish, but elsewhere the laminated 
upper clays contrasted strongly with the tough boulder clay, and 
here and there the surfaces were irregular at the junction, 
especially near the pits, cutting the line of junction. 
Turning, now, to the N. boundary, the beds differ consider- 
ably. The difference is not great at the east end, where the bank 
is only 25 feet from the drainage trench. Here the beds are not 
distinctly connected with those of the lower level. 
The northerly trend takes the bank 200 feet off at the W. end 
of the Goods Station. About half-way is a recess, 120 feet 
across, and 25 feet deep to the east, 80 to the west. The beds 
round this are very much twisted, as was shown for the W. side by 
Photo. VIII. A pile of round stones, the largest to the N., looking 
as if shot off an ice-berg, and a clay-line proceeding N. from it 
with twisted beds above and below are most noticeable. Beyond 
this, running at an average depth of 4 feet, but sometimes much 
lower, is a nearly continuous bed of pebbles and boulders of all 
kinds. 38 feet from the corner, (Photo. VII. , Plate XXIII.,
