Phillips 1814
|
|
|
These notes are taken from a geological map of the Hampshire
or Isle of Wight Basin by W Phillips, published with an article
by Thomas Webster, in Transactions of the Geological Society,
vol.2, London, 1814. The map studied is in a private
collection.
|
|
The map is colour printed in pale shades of brown. Its size
is: wxh, sheet = 56.5x26.5cm; wxh, map = 516x209mm. The notes
made here have a strong bias to Hampshire interest.

Printed lower left of centre is a north point; N-S line, E-W
cross line, North marked by an arrowhead, a small cross line
marks South. The map is printed with North at the top of the
sheet.

marked and labelled at 1 mile intervals. The 10 miles = 41.2
mm gives a scale 1 to 390617, there is no reason to doubt a
statute miles is meant. The map scale is about:-
1 to 390000
6 miles to 1 inch
|
sea area
sea plain
|
The sea area is plain; some areas are labelled, eg:-
SOLENT
Southampton R. [Southampton
Water]
Stokes Bay
|
coast line
foreshore
headlands
harbours
|
The coast line is plain. Foreshore shallows are indicated by
dotting, and rocks by crosses (+) which might be labelled. The
coast line is accurate and headlands and harbours can be
recognised easily. Few are labelled, eg:-
Christchurch hd. [Hengistbury
Head]
A number of cliffs are labelled, eg:-
Hordwell cliff
Barton cliff
|
coastal defence
castles
fortifications
|
Little of the coastal defences is noticed, old castles or more
recent fortifications. In Hampshire:-
Hurst Cast.
South sea Cas.
Cumberland Ft.
|
rivers
|
Rivers are drawn by a wiggly line tapering inland, perhaps
labelled, eg:-
Avon R.
Lymington R.
R. Exe or Beaulieu
All the main rivers of Hampshire are shown, with braiding and
tributaries.
|
relief
hill hachuring
|
Hill hachuring i used to indicate relief. The:-
SOUTH DOWNS
are shown and labelled, and the general rise of the land in
Hampshire north of Hambledon - Bishops Waltham - Otterburn -
Romsey etc, is clear. River valleys are clearly marked. While
hachuring is a qualitative rather than a quantitative method of
showing relief, its use on this map does manage to suggest high
ground in the right places.
|
woods
forests
|
Woodland is not indicated by symbols, though, in Hampshire,
there are labelled:-
New Forest
Bere Forest [East Bere
Forest]
|
county
|
County boundaries are not noticed. The inclusion of Hampshire
and the Isle of Wight is noted in the map title.
|
settlements
|
Settlements are positioned by a circle. They are
differentiated a little by style of lettering, perhaps by size.
Smaller places are labelled in italic lowercase text; larger
places in bold upright lowercase text. In Hampshire, Portsmouth
and Southampton, are large; all other places, including
Winchester, are small.
Places are included to orientate the map reader, not to show
places.
The map includes the south coast of England from Portland Bill
to Beachy Head, as far north as Salisbury and Winchester,
Horsham, etc. Parts of Dorset, Wiltshire, Hampshire, West Sussex,
Surrey, and the Isle of Wight. Thus the south of Hampshire is
covered, towns:- Bishops Waltham, Christchurch, Fareham,
Fordingbridge, Gosport, Havant, Lymington, Petersfield,
Portsmouth, Ringwood, Romsey, Southampton, Winchester.
Another map, the London Basin, published with the geological
article, includes the north part of Hampshire, towns:- Alton,
Andover, Basingstoke, Kingsclere, Aylresford (sic), Odiham,
Stockbridge, Whitchurch, Winchester. The two maps together cover
?all Hampshire.

GEOLOGY |

geology
table of strata
|
The map is drawn to demonstrate the geology of the region,
showing the extent of three geological units explained in a table
of strata printed lower right:-
Chalk [white area]
Strata above the Chalk [pale brown
area]
Strata below the Chalk [grey
area]
For the whole geological commentary you must go read the
article by Thomas Webster! The description of the plate is:-
Plate 9. Map of the Basin of the Isle
of Wight, shewing the hollow occasioned by a depression in the
chalk within which some of the more recent strata appear to have
been deposited; and also a part of the district in which the
chalk is found wanting, where the strata below the chalk are
exposed, p.168 and 170. The detached figure below represents on a
larger scale the west end of the Isle of Wight, where the section
of Pl.11 is taken.
The associated plate is described:-
Plate 10. Map of a similar Basin in the
vicinity of London, p.171, 172.
Page 168-170 has:-
The chalk of the middle hills of the
Isle of Wight dipping to the north, and that of the South Downs
dipping to the south, it was an obvious inference that it might
pass under the channel called the Solent, thus forming a basin.
The idea was rendered still more probable on finding that the
bottom of this channel consisted mostly of the London clay, which
stratum is found under Portsmouth, whence it may be traced
eastward, forming the lowermost bed next the sea all along the
shore of Sussex to Pagham and Bognor, and westwards to
Stubbington cliff, and along the coast of Hampshire to Hordwell
and High cliffs. In all its characters and fossils, this bed was
found to agree with the blue clay which lies over the chalk, in
the counties of Kent, Surrey, Middlesex, Essex, &c. and with the
most northerly of the vertical beds of Alum bay ...
It appears, therefore, that between the
vertical chalk-hills of the Isle of Wight and the South Downs
there is a basin or hollow, occasioned by the disturbance of the
whole mass of strata from below the chalk to the London clay,
inclusive: and also that this disturbance took place at a period
subsequent to the deposition of the last-mentioned stratum, since
it is amongst those which have suffered a change of
position.
From this it will be readily admitted,
that all the beds situated within this basin lie above the London
clay, and are posterior to it. Of this description are the
horizontal beds of the most northerly part of the Isle of Wight;
and since they come almost into contact with the vertical beds
without suffering any considerable change in their dip, it should
seem that they have been deposited on the sides of this basin
subsequently to the disturbance of the strata already spoken
of.
