The stones in the loose strata of gravel and sand are some of them 
Avell striated. The thickness of deposits on the top of the hill, is 
much greater than below. 
This bank, and another contiguous to it, appear to be extensions 
ot moraine matter from the higher grounds of Lindale Moor, High 
Banks, Carr Kettle and AValthwaite iSIoors, and lie immediately be- 
tween these and the Plain of Swarthmoor, which is one large spread 
of boulder clay. Gill Brow would moreover, in all probability, form 
a side bank on the great ice-flood line of the Pennington Beck, al- 
though now situated nearly a mile from the stream. The loose gravel 
stratum therefore might be part of tlie delta of that flood. JNo other 
suggestion presents itself to my mind. The striatious would forbid 
the gravels beinsj regarded as marine. 
In the section formed by the railway-cutting, now grown over, the 
stratified beds were observed '"running in very thin seams" through 
tlie boulder clay. They seem to be a constant and familiar accom- 
paniment to that deposit, in the Carboniferous and Silurian grounds 
of Furness. AVith the boulder clay on the Permian, 1 am not yet so 
well acquainted. Its most southern inland extension, 1 believe, is at 
Harbarrow, three and a lialt miles from the south point of Furness ; 
not far from here, it probably declines down under the red marl of 
Leece. In piercing through that deposit, near the Leece Tarn, for 
water, it was supposed to be the boulder clay that was reached at the 
depth of 112 feet. 
Stratified Marine Drift. — It does not appear that the stratified 
marine drift of Furness can be said to attain in any thickness, to 
elevations niuch above 100 feet. Travelled and un:>triated boulders, 
some of great size, water-rolled stones foreign to the district, and 
stray fragments of shells, are certainly met with ; the latter even up 
to 500 feet, but no undisturbed truly marine deposits exist at such 
elevations to my knowledge. Several large stones, quite foreign to 
the district, occur upon and in the boulder clay of Lindale and the 
neighbouring moors ; whether they may be regarded as the remnants 
of out-swept marine drift, and as marking the base of renewed gla- 
ciation, it is difficult to say. Many of them, notwithstanding their 
hardness, liave all the appearance of glacial friction, being much 
smoothed down and flattened. 
Probably they are marine deposits, which we find lying above a 
mile in shore, at the Ulverstone Kailway Station, and extending up 
the Pennington Vale, to a little above 100 feet ; but I believe these 
are met by, and to some degree commingled, and interstratified with 
old fluviatile deposits. 
In sinking a well some years ago on the south of the town, be-
