A Group of Mounds on Seasalter Level, near Whitstable, and the Medieval Imbanking in this Area
A GROUP OF MOUNDS ON SEASALTER LEVEL, NEAR
WHITSTABLE, AND THE MEDIEVAL IMBANKING IN
THIS AREA
By M. W. THOMPSON
THE origin of the mounds that are so commonly found on the marshes
around the British Isles has always been a perplexing problem. The
Essex Archaeological Society, it wUl be remembered, after several
seasons' excavation on the Red HUls in the Essex marshes were unable
to decide Avhat activity had caused theh accumulation, and it was only
ten years later that Mr. R. A. Smith1 by the use of convincing Continental
paraUels was able to show beyond reasonable doubt that they
were the remains of salt works, where sea-water had been evaporated
by an unfamUiar method. A few years later other members of this
Society excavated further mounds, taller than the Red HUls, without
briquetage and of Medieval date.2 They concluded they Avere salt
works also, a view lent some support by the enclosures adjoining them.
In the mounds Ave shall discuss below there was practically no briquetage
and very little red earth; the mounds were clearly Medieval in date and
not Roman or Iron Age like the Red Hills; and on Sheppey (within
sight three mUes away) the dialect Avord " coterells,"3 apparently of
ancient origin, suggested that the mounds there may have been thrown
up as refuges for cattle and sheep during tidal flooding. For these
reasons we were reluctant to regard these mounds as salt works until
the bulldozing of further intact mounds showed such frequent traces
of burning that the conclusion became unavoidable that some industrial
activity was involved.
Although we have no specific documentary proof we propose to
assume from the start that our mounds were salt works, whUe of course
not ruling out the possibility that this may need correction. Dr.
Bridbury4 has recently given an account of salt-working by the evaporation
of sea-water as practised in Medieval Europe. We may note one
or two points about this still very Ul-studied subject. Firstly it is

3 O.E.D. As the word is not known before the eighteenth century its etymology
is uncertain. Leland, it may be noted, uses " ooots " or " oootes " for
coastal and inland evaporation works, e.g. " . . . a groat number of salt ooots or
furnaces . . . wherein the salt water is docoote . . . " (Itinerary, ed. Toulmin Smith,
n, 92-4).

reasonably certain that in the Enghsh climate the evaporation was
largely done by artificial means and not by the sun. The methods we
will discuss later, but it is most unhkely that the briquetage method of
Roman times Avas in use anywhere. Secondly, Domesday shows us
that evaporation was carried out over very extensive areas, Kent being
one of the more important counties. Thirdly, Professor Darby1 by
plotting the Domesday entries manor by manor in the eastern counties
has shown that salt works were frequently up estuaries, or in fenland
or in parishes Avhere extensive marsh areas separated the manor from
the sea proper. Fourthly, it is knoAvn that such salt works sometimes
led to the accumulation of mounds. An early fourteenth century
terrier from Fleet, Lincolnshire,2 shows the salt works divided into
units of a " hoga cum area." Hoga is apparently the Latinized form
of the modern " howe," used in Yorkshhe to describe a barrow or
small hUl.3 An Ehzabethan map of Fulstow and Marshchapel, Lincolnshire,
shows the " round groundes " in the marsh which were " first
formed by layinge together of great quantities of mould for the making
of salte." Those in use had cottages upon them.4 Leland, who saw
the primitive coastal salt industry in Lancashire that survived until the
eighteenth century, actuaUy described heaps of sand being pUed up.6
Some two mUes west of Whitstable lies an extensive area of marshland
about two miles across from east to west and one from north to
south (Fig. 1). It is bounded on the north by the sea-Avail separating it
from the Swale and on the three other sides by hiUs of London Clay. In
the north-Avest Boughton marshes pass round the north of the Graveney
promontory to link up with the extensive marshes around Faversham.
The marsh is divided into fields by a web of straight dikes, but clearly
distinguished from these are tAvo or three meandering streams, which
normally mark the parish boundaries. One of these enters from the
south-east, another from the south-west; turning towards each other
they join and flow northwards to the Swale. The parish of Hernhill
lies on the south, that of Graveney to the north-west and Seasalter to

give a misleading idea of their appearance. In Kent in the thirteenth century the
English word was " wychwerke " (E. Thorold Rogers, Hist. Ag. Prices in England,
i, 456).

secondary use, for when they became too big new ones were started farther out,
while those abandoned became pasture.

the north-east. The mounds Avith which we are concerned are shown
on the accompanying sketch plan (taken from O.S. six-inch first edition,
the Tithe map of 1840 and a modern ah photograph), and as can be
seen, lie close to these streams, mainly in the south in Hernhill, but
there are several farther west in Graveney and one or two in Seasalter.
The construction of the railway in 1841 caused some alterations to be
made, but the Tithe map of a year earlier shows that Mound B formerly
lay in the bend of a stream which flowed south-westward. Traces of
two counter waUs survive, the more easterly probably following the
course of a now vanished stream just to the north of Mound B.1 The
mounds have no special name now, but in the Tithe map mounds H, I
and K lay in HU1 Marsh, G and F were called respectively Hawkins and
Second Hawkins HUls, and D and E lay in Great and Little Hill Marsh.2
During the nineteenth century, as the Tithe maps record, the whole
marsh area was used exclusively for pasture, but in the last few years
some of it has been brought under the plough. To prepare the land for
ploughing bulldozing of some of the mounds began in September, 1955.
Mound A was bulldozed first, and then Mound B. When about two
feet of Mound B stUl remained objects of wood came to light, including
what was at first taken to be a boat. The matter was reported by

derived) as can be seen on the six-inch O.S. sheets of Sheppey. The westerly
counter wall is specifically mentioned as such in " An Inquisition and Presentment

Valley in the County Archives at Maidstone.

family who owned extensive areas of the Hernhill marshes from Tudor times to
the eighteenth century.

Councillor Harvey to the Inspectorate of Ancient Monuments in the
Ministry of Works who decided to carry out an excavation. Four
weeks' work were carried out by the author and Miss S. A. Butcher in
October, 1955, who also made frequent visits to the site during the
buUdozing of Mounds C, K and F.
The mounds are rarely chcular in plan or regularly domed in
section, but oval or kidney-shaped, about 150 to 250 feet long, and
commonly with two or more lumps often on the north or seaward side.
The maximum heights vary from about seven to over fifteen feet in
.the case of E and G. The two latter mounds are exceptionally large.
The mounds are not shown on the ordinary O.S. sheets, but are shown
as protuberances of London Clay through the marsh on the Geological
sheets. The five buUdozed mounds are certainly artificial heaps of
marsh clay, and there can be no reasonable doubt that this is the case
with all the mounds.1
At the time of Domesday and Domesday Monachorum2 Hernhhl
had not appeared as a separate manor, although its church is mentioned
in the latter. It probably formed part of Boughton under Blean.3
Boughton and Graveney were primarhy agricultural villages, although
the former had one salt works and the latter four. Seasalter, in spite
of its name, had no salt works recorded, although it did have an extensive
oyster industry. Until the time of imbanking in 1325 Ave have no
further documentary evidence, but unfortunately it is precisely to this
intervening period that the pottery leads us to believe our mounds
belong.
In 1325 a petition from Thomas of Faversham (holder of the manor
of Graveney) was forwarded by Prior Henry of Eastry of Christchurch
to the Archbishop of Canterbury asking him to contribute his share
to the cost of imbanking the marshes in Boughton, Hernhill, Graveney
and Seasalter,* seven hundred acres of marsh being involved, of which
one hundred were held from the Archbishop. The project proved
much more costly and difficult than had been supposed, for the evidence
of Avitnesses in 13296 showed that a substantial bank over a mile long
(three hundred and twenty perches) and forty feet broad (two perches)
had been thrown up in 1325, but that over a thhd of it had been swept
away by the sea within a year or two. Some of the tenants were
unwilling to contribute theh share of the costs, and it was only due to

the perseverance of Thomas's son and the Archbishop that the marshes
Avere finaUy sealed by the directions of the Commission of 1340.1 Evidently
difficulties did not end here, for Commissions de Walliis et
Fossatis in this area are recorded in the Calendars of Patent Rolls
during the rest of the century (e.g. 1363, 1370 and 1380), and for some
reason difficult to understand HernhiU marshes (Avhich do not abut on
the sea) were the subject of special commissions in 1374, 1376, 1377
and 1379.2
The sea-waU Avas started from both ends; " from the water-miU
towards the east " on the Graveney side and " from Seasalter towards
Heyfleet " on the other.3 There was probably some kind of beach
along this line or part of it, and there can be no reasonable doubt that
this was on the line of the present Avail. Mr. C. F. MUlard of the River
Board teUs me that the present beach of cockle sheUs in front of the
sea-wall does extend under the sea-waU. In 1325 a Stonberk Marsh
is mentioned among those to be enclosed, which is presumably the
Stonbache Marsh of 14814 and the Stone Beach Marsh of 1739 which lay
by the Red Sluice.5 This name presumably refers to a beach existing
before the wall Avas thrown up. The Heyfleet extended from the seawaU,
under le HU1 (possibly a reference to a mound) to Phtiek, and is
almost certainly the old stream course by which the Hernhill mounds
lie, for it more or less corresponded to the parish boundary between
Hernhill and Seasalter. From 16806
the annual accounts of the
Commissioners for the Seasalter Valley are preserved and show the
sea-wall more or less as today. One of theh main items of expenditure
was the cost of " cutting " (presumably the reeds), " drawing " (dragging),
and " fleeting " the three streams, which are clearly distinguished
from the ordinary dikes, and no doubt represent the courses of streams
before the imbanking on the one hand and the three streams which are
at present distinguishable on the other.
In the foregoing we have shown that before the imbanking the
Hernhill mounds lay by a stream not very far from its mouth into the
sea in a lower part of the marshes. This is to some extent confirmed
by the effects of the great flood of 1953, for it was precisely in the area
of the mounds that the depth of water was sufficient to sweep away the
rahway embankment, and where observers report the water lingered two
or three weeks after it had drained off the rest of the marsh (see Plate I).

The general level of the marsh around Mound B is 5-4 feet above
Ordnance Datum (Newlyn), whUe the tidal levels in the Swale in front
of the sea-AvaU are approximately: Mean High Water Spring 8-7, Mean
High Water Neap 5-5 (feet above O.D.), and Mean Low Water Neap
5 • 2, Mean Low Water Spring 7 • 8 (feet below O.D.) ,1 Clearly, therefore,
if the sea-wall were removed this area would be flooded at every tide.
If we make aUoAvance for the rising sea-level, which Mr. John Evans
has shown played such an important part in the formation of the north
Kent marshes,2 we should be able to form some impression of conditions
prevailing before the imbanking in 1325. Clearly the seven hundred
acres divided among tenants mentioned in 1325 were never flooded
regularly, but the indenture of 13403 speaks of twelve hundred acres
of marsh and pasture being saved " not only in the marshes but in
adjacent parts". We may envisage the marshes before 1325, then, as
partly regular pasture in the higher parts but with an area subject to
flooding at the centre unsuitable for pasture. The incoming tide would
advance from the Pollard across the present flats, and then slowly flood
the lower part of the Heyfleet, the eastward and westward spread
depending on whether it was a spring tide or not.
In this way we can perhaps explain the curious siting of the mounds
by the old stream course, whUe theh proximity to the high ground
would be explained by the convenience in bringing fuel and tools to the
site. It wUl be noted that in the HernhUl group aU the mounds except
A and K are on the landward side of a stream. Surely it is unhkely that
cattle or sheep refuges would be placed where, in the event of severe
tidal flooding, stock on this side could easily scramble on to natural
high ground a few hundred yards away, while stock on the seaward side
would be cut off by the swollen stream from any kind of refuge at all.
The astonishing height of the mounds is no doubt partly to be explained
by the severity of flooding, which we know took place just before and
after the wall was buUt, and for which there is abundant evidence from
elsewhere during the thirteenth century.*

4 The imbanking in the Romney Marshes began early in the thirteenth century
(Dugdale, op. cit., 27) where exceptional flooding was common, while Matthew-
Paris (Chron. Maj., R.S., iii, 379, 387, and v, 170, 264, 418, 461, 607) refers repeatedly
to disastrous tidal flooding. There is indeed a suspicion, not more, that the
site of the Domesday church at Seasalter had to be abandoned for this reason in
favour of that of the present Early English building on the hill (Hasted, Hist, of
Kent, iii, 552), for the great storm of 1779 revealed the foundations of a rectangular
stone building (and numerous human bones) on the beach near the Blue Anchor,
which it was considered might be the remains of a church. Councillor W. C.
Harvey tells me that recently further bones have come to light at this point.

EXCAVATIONS
(in collaboration with Miss S. A. Butcher)
Mound A had aheady been bulldozed level when we entered the site.
I t had evidently been made enthely of marsh clay and the large area
over which it had been spread was of a slightly lighter colour than the
surrounding ploughed field. Small patches of burnt clay and charcoal
were found here and there, and several pieces of Medieval pottery were
picked up.
Mounds C and K. Both these mounds were of very characteristic
shape with their highest part on the seaward side. Only the earlier
stages of bulldozing Avere Avatched. Both mounds were made up of
marsh clay with patches of reddened clay. The bulldozer operator
reported that " paths " and " mats " made of pieces of wood as in
Mound B were found in the base of Mound C. One small wicker lined
pit was dug out by Miss Butcher at the base of this mound. It was
simUar to pit 3 on Mound B (see p. 52). There was a certain amount
of charcoal from this mound and a number of sherds of Medieval
pottery particularly from the top. Mound K only yielded tiny fragments
of pottery and a very little reddened clay, although near the top
the base of a roughly rectangular pit (four feet by two feet six inches)
with sides of interweaved wickerwork was exposed.
Mound F. The eastern of the mounds that form this group of
mounds has been leveUed and its material used to fill the adjoining
stream (July, 1956). Unfortunately we were only able to inspect the
site when this had aheady been carried out. The mound was quite
distinct from the others in the quantity of burnt material found in it.
At the base on the landward side a large area of burnt material about
one hundred and eighty feet long by fifty feet wide (not less than two
feet deep according to the explorations of the bulldozer operator) came
to light. Sherds, bones and appreciable quantities of lead (several
pounds at least) were found on the surface of this burnt area, which has
not been fully explored.
Mound B. Four weeks' excavation were carried out on this mound
by Miss S. A. Butcher and the author in October, 1955, with the kind
permission of the owner, Mr. Spencer King.
The mound was oval in shape, measuring about one hundred and
eighty by one hundred and thirty feet, but probably the rahway and
the dike on its west side had trimmed off its edges (Fig. 2). The Tithe
map shows that it formerly stood in the loop of a stream on its southern
side, and at that time had a buUding on it, rather as one of the mounds
in group L has at present. At the beginning of the excavation the mound
had aheady had its upper part sheared off by the grader to a level
about two feet six inches above the level of the surrounding marsh.

FIG. 2. Mound B, sho\raig trenches and features uncovered.
We were told that there had originally been two high places on the
north side six to eight feet higher than we found it.
The position of our trenches can be seen on the accompanying plan
(Fig. 2). A section was drawn from north to south, but the information
it yields is so slight that we did not consider worth while reproducing
it here. No signs of stratification are detectable in the intractable
marsh clay. AU over the central area at about two feet below the
surface the marsh clay changed abruptly from brown with reddish
51
MOUNDS ON SEASALTER LEVEL, NEAR WHITSTABLE
streaks to grey with bluish streaks. This is, no doubt, the level below
which oxidation of the hon salts to red ferric oxide cannot take place.
This view is lent some support by the fact that all round the mound
as one approached the perimeter in any dhection this change in colour
took place deeper and deeper, the thinning of the superincumbent
mound no doubt allowing more oxygen to penetrate. This change
must have been at or near the old ground surface at the centre, which
was not otherwise distinguishable. For our purposes we may distinguish
structures found on or near this level and those exposed on the
surface by the bulldozer, although we must not, of course, assume
structures at the same level are contemporary.
On the north side oyster shells were scattered over the surface.
A trench through these showed it was not a horizontal scatter but they
dipped down in section towards the edge of the mound and evidently
had been thrown out from above when the mound was partially made.
On the east side of the mound a lined pit was exposed by the buUdozer,
pit 3. This measured two feet eight inches and two feet ten
inches by three feet two inches and three feet four inches. The bases
of the uprights were preserved. Those at the corner were about one
inch thick, with smaller ones set between, the whole bound together
with twigs. The pit, which was dug out by Councillor Harvey, contained
black vegetable matter, pottery, and some wooden objects.
There was no made bottom to the pit.
The bulldozer had scattered burnt material over a large area, but
two conspicuous areas were visible to the south of the centre of the
mound, oval in shape and approximately eight by five or six feet.
These were composed of charcoal, burnt wood and baked clay.
Beneath the eastern burnt area pieces of wood and reed were found
to a depth of about four feet, that is well into the grey clay. The
material was quite unstratified and gave the impression that the area
had been churned up, perhaps by people wading about in the soft mud.
Two paths, made of short pieces of broken- sticks laid roughly
parallel a few inches apart, were found in the southern part of the
mound. The southern ends had probably decayed. They converged
and met, and turned eastward leading up to pit 2. Just before this
point a similar path of reeds led in from the right. This short piece of
path, like two pieces farther north, had longitudinal strips along their
edges.
Between pits 1 and 2 two rectangular hurdles lying horizontaUy and
measuring about five feet by three feet six inches came to light. These
were made of twigs with reeds over the surface. Only in one case were
the twigs interlaced between the uprights. They did not appear to be
fallen as there was no means of holding them upright, and they were
perhaps intended to act as a firm platform on soft mud.

Two oval pits, 1 and 2, measuring approximately six to seven feet
by five to six feet, which had been dug into the old ground surface were
found in the positions shown on the plan. Pit 1 was about two to three
feet, pit 2 four to five feet deep. In the soft clay which surrounded
them it was impossible to determine the dimensions accurately. They
both contained a great deal of vegetable matter, indeed the methane
emitted from pit 2 was accidentaUy set alight and burnt for several
minutes. The burnt material from the western burnt area poured
down into pit 2, which was evidently only partiaUy filled when the fire
was lit. Pit 1 yielded some sherds of medieval pottery and parts of a
leather boot.
Both pits had some kind of cover or lid made of substantial unshaped
timbers, which have been identified as oak. In pit 2 three heavy cross
pieces or ribs lay in the pit and were covered with a mass of smaU
twigs, obviously arranged and possibly intertwined between the ribs.
Pit 1 was wholly covered by timber work which, sagging in the middle,
gave the appearance of a shallow boat for which it was at first mistaken.
I t was formed of four massive cross timbers or ribs of unworked wood
lying lateraUy across the pit (Plate II). These were up to five inches in
diameter and seven feet long. Down the middle on the upper side was
laid a thin branch one to one and a half inches thick and with its bark
still adhering. A good deal of wickerwork was found on the upper side
laid in such a way that it seemed as though the timbers were held in
position by this.
DATING AND CONCLUSIONS
A list of the objects found is given below, and Mr. G. C. Dunning
has achieved a fahly close dating from the pottery, but even a cursory
glance at the drawings wiU show the reader that the pottery found is
homogeneous and of Medieval date. Material of no other period was
found on or near the site, while some of that Ulustrated was found
beneath and in Mound B. Moreover the leather boot which is nondurable
in the open ah must be roughly contemporary with the pit in
which it lay. The dating for Mound B is therefore about as strong as
it is possible for archseological evidence to be. The other four mounds
are also dated by pottery, sometimes from the make-up or beneath the
mound, and are clearly of roughly the same date. There can be little
doubt that the whole group of mounds served the same purpose and are
probably of roughly the same date (to within a century or two). Four
of the mounds bulldozed out are fahly peripheral, but material from
Mound F, which is near the centre of the whole group of mounds, seems
to be of a very simUar date.

which the mound was thrown up, neither of grass nor of reeds. The
footpaths and probably the hurdles1 suggest that the surface was a soft
one on which it was difficult to keep a foothold. Such a surface could
surely only be tidal mud flat.
The only modern human activity on such an unpleasant surface is
the collection of shell-fish or worms for bait, which does not of course
lead to the accumulation of mounds. If, however, we return to our
original assumption that the mounds owe their existence to salt-making,
Ave can hazard a guess about the purpose of some of the structures found.
Of the six methods of making salt listed by BroAvnrigg it is clear that
only methods 3 and 4 could have been used here.2 Method 3 involved
partial evaporation by the sun and then boiling. Possibly in warm
Aveather such a method AAr as used, but it is more likely that at HernhUl
salt was made by method 4, " . . . from strong brine or hxivium
drawn from earths, sands or stones impregnated with common salt."
This method was used with sand in the Lancashhe industry, but what
modification would be necessary for mud it is difficult to say. Brownrigg
says that in the Lancashhe industry the sand was collected from
the surface of the spring tide zone in great heaps, and then put in pits
fined with straw or rushes, the salt being filtered off and the sand
constantly replaced. Perhaps the vegetable matter in our pits 1 and 2
had a similar purpose.
Collins3 tells us hoAV to lay out a salt Avorks in " sea mud, oase or
sleech." The preliminary evaporation was done in open pans by the
sun, but the brine so prepared should be kept in cisterns eight feet deep,
dug in the mud and lined with " posts of timber Avith hurdles between
them, the ground being such as will not imbibe the liquor . . ."
For winter boUing the cistern was covered with a roof, tiles being
preferable to thatch, and then it was called a brine house. The whole
is very reminiscent of what was found on our site, although if our pits
1 and 2 were cisterns or brine pits they were not lined and were shallower
than this. The covers on our site may have been simply to stop the
rain dUuting the brine, but the great thickness of our timbers suggests
they were intended to take some weight, perhaps to support the mud
during the straining process.
The receptacles used for boiling may have been of earthenware, but
these are rather smaU and in Lancashire lead pans were used. It is
therefore of interest that a smaU piece of lead was found in Mound B,
whUe Mound F yielded very appreciable quantities of this metal.
Indeed, as Miss Butcher points out, the very large burnt area in this

Estuary which it is believed were used in just this way.

mound suggests that possibly the main boiling was done here whUe
only the preliminary concentration was done in the outer mounds.
THE FINDS
The Boot (Fig. 3). This is perhaps the most interesting find made
on the site. It was found in the vegetable matter in pit 1 and therefore
is securely stratified. Mr. John Anstee of the Museum of English Rural
Life at Reading has very kindly given the following report and made
sketches on which the figures here are based.
" This boot is extremely interesting as it is radically different in
style from the majority of Medieval shoes that I have seen.
" From the general condition of the remaining fragments, and the
fact that the outer sole is missing, I would suggest that it had been
thrown away and not sucked off a foot in the mud. The boot, as
restored after detailed measurements of the original, and experiments
with leather cut to the drawn plan, is eleven and three-quarter inches
long and four and a quarter inches wide across the sole; that is size
nine of a male left foot.
" The fragments consist of the following: (a) most of the main upper,
(b) a smaller quadrilateral insert to this, (c) two complete pieces of
upper edge binding, (d) fragments of the inner sole, (e) triangular patch,
almost certainly a toe reinforcement for the sole. The main upper had
been cut out with a minimum of wastage, pierced with lace slits and
sewn on every edge. Stitched to it by three edges was a smaU hregular
.quadrilateral piece whose fourth edge (forming part of the circle of
boot top above the ankle) had also been stitched. This stitching of the
top is unusual; at first I thought it proved the presence of an additional
upper around the lower leg.
" At an early stage in the restoration no definite measurement could
be fixed for the open boot top and it was thought that there must have
been an unsewn but closable seam in the missing back portion of the
upper, in order to get the foot in before lacing up. This laced seam is
quite usual in Medieval boots but it can exist anywhere in contrast to
the modern preference for having it at front. The Avhole problem was
clarified by the discovery that two complete strips three-eighths of an
inch wide and eleven and three-quarter and four inches long respectively
formed a narroAV strengthening binding to the open top of the
boot by being stitched to the two pieces of the upper (A—B in Fig. 3).
These strips were made by single folding of pieces of leather threequarters
of an inch wide up the middle and sewing them downwards on
to the rim of the upper. The ends of the longer strip were enclosed by
the fold of the smaUer strip for distances of hah7 and a quarter inch
respectively. This gave a chcumference of fifteen or diameter of 4 • 8

inches for the top of the boot. The exact position of these strips in
relation to the upper was proved by stitch runs that fitted perfectly.
The above clue made it possible to restore the back of the boot, and
indicated that the larger upper fragment was almost certainly sewn on
to itself at the main vertical seam on the outside of the foot. It also
proved that a size nine male foot would pass through the orifice and bed
down comfortably within the confines of the estimated sole; in fact no
adjustable lace-up seams were necessary.
" It wUl be seen that when placed on the foot this type of shoe was an
extremely loose fit above the ankle. This looseness was taken up by
drawing the string or thong (which passed through the slits, D in Fig. 3)
tightly from both ends and tying them at a point under the inside ankle
bone, where there are no lace slits on the original (E). On the restored
plan (Fig. 3, F) two more lace slits have been shown, one at an obvious
point behind the ankle and another to conform to the regular spacing
between those showing on the original. This method of tying removes
the necessity for the gusseted heel inserts to be seen on many Medieval
boots, where they provided a more comfortable fitting Avith a tight top
and lace-up seam. There is just a possibility that the triangular piece
of leather is just such a heel gusset but attempts to fit it into the
restored patterns upset the definite evidence of known measurements
and the natural horizontal line of the boot top. I can only suggest
that this fragment is a reinforcement for the tip of the sole. In this
position it completely alters the shape of the shoe but the result looks
exactly like other undated Medieval shoe soles that I have handled.
" The few fragments of a thin inner sole do not show clearly how it
was attached to the upper but it is probable that they were sewn
together inside out and then turned, the thicker outer sole and reinforcing
toe piece being added afterwards.
" This boot appears to be an important dated example in a field of
study stUl much neglected. The principle of the drawn thong reminds
me vaguely of an Indian moccasin, and the whole arrangement is what
one might expect an unsophisticated Medieval peasant to wear."
Wooden Objects. Apart from the paths, pit covers and hurdles a
great many pieces of wood of varying sizes and shapes were found in
Mound B. Usually these were unworked, but a number of pieces of
board came to light. Some of this may have been waste wood for fuel,
but this mound as well as Mounds C and F produced some objects
which are worth recording.
" Rakes." From Mound B, pit 3, -6 inches thick, 3-2 inches broad,
19£ inches long. Through the centre was a perforation • 6 inches broad,
(Fig. 4, 1). From Mound F, -5 inches thick, 4-8 inches broad. This
had two perforations set close together • 5 and • 8 inches broad (Fig. 5,1).

Hoe-like object from Mound F, 5-4 inches broad, not less than
19 inches long with a large perforation 1*2 inches in diameter. One
end pointed (Fig. 5, 2).
Rough bowl, 1 foot in diameter across broadest part just above
base, from Mound C (Fig. 5, 3).
Cylindrical piece of wood 1 • 7 inches in diameter Avith a deep V-cut
along it (Fig. 4, 4).
A kind of mallet head from pit 3, Mound B, 7-4 inches long, 3-5
inches broad and 2-5 inches thick, Avith a perforation hregularly placed
toAvards one end which is -7 inches in diameter (Fig. 4, 2).
The figures in Agricola's De Re Metallica show that the tools of the
German salt boUer in the early sixteenth century were made almost
enthely of wood except the metal boUing pan.1 The object he calls
" rutrum " which is a prongless rake of wood is very much like what our
" rakes " must have looked like when fitted with a handle, whUe the
" batillum " which is a hoe-hke object with a large blade Avith a pointed
butt seems to be what our hoe-like object Avould look like when it had a
handle fitted. They seem to have been used for removing the dirt and
froth that came to the top of the pan in the early stage of boUing and
for the later removal of the salt crystals as they formed at the top.
Lead. A small, quite shapeless piece of lead was found in Mound B.
SimUar shapeless pieces were found in Mound F by the bulldozer
operator, but of larger size and in much greater quantity.
This lead Avas presumably waste from work on the boiling pans.
We have noted that these were of lead in the Lancashire industry.
Agricola said they could be of hon or black lead and should be eight feet
long, seven feet broad and six inches high. As they were made of
rectangular plates almost three feet square (presumably for convenience
of transport) they probably had to be assembled and mended on the
site.2
Hone. A fragment of the end of a hone, 2-9 inches broad, Avas
found in Mound F.
REPORT ON POTTERY FROM SEASALTER (Figs. 6-7)
By G. C. DUNNING, F.S.A.
The material from the four mounds (A, B, C and F) shows the same
range of pottery types and of rim-sections, and the same qualities of
Avare occur at each site. The majority of the sherds are from cooking
pots, representing fourteen vessels, and there are fragments of two

dishes and three jugs. It AVUI be convenient first to describe the
different types, and then to discuss the analogies and dating.
Cooking-Pots
The rims of the large cooking-pots are Avell developed, and may be
divided into five groups:
(1) Thickened outside, forming a flange (B2-5).
(2) Flanged outside with a vertical outer edge, and well marked
concave bevel on inside (B6, C3).
(3) Pressed doAvn outside, and marked by thumb impressions
(Cl-2).
The above groups comprise pots of coarse Avare, and all have
a free admixture of crushed white shell Avhich speckles the
surface. A few of the pots also contain sand in the fabric in
addition to the sheU.
(4) Rims thickened outside and beveUed on inside, or flanged
outside and flat topped (Fl-2).
These are of very hard sandy ware, and the shell is absent.
(5) Small rims shghtly thickened outside, and more regularly made
(Al-2, Bl, F3).
These are of finer quality sandy Avare.
Dishes
A large rim (B7), heavily flanged outside and marked by the fingertip
along the top of the flange, and beaded on the inner edge. A smaller
rim (A4'l has a plain flange and inner beading.
Jugs
Fragments of very different type and ware, one from each mound.
Squared rim with ridge below it outside, of grey shelly ware, red
surface (A5).
Upper part of body of jug with zones of combed lines, of thin grey
sandy ware (B8).
Handle, sharply grooved down the back, of hard orange -ware (04).
DISOT/SSION
In seeking to date the Seasalter pottery, comparison must be made
with a long series in the same region, for which the sequence is established
and the dating knoAvn within approximate limits. Fortunately,
such a series is available from the post-war excavations at Canterbury,
and several groups have aheady been published by Mrs. Audrey Williams
and Mr. Sheppard Frere in Archaeologia Cantiana. The reports are on
sites in St. George's Street (Vol. LIX), Watling Street (Vol. LX), Butohery
Lane (Vol. LXI), and Rose Lane (Vol. LXVIII). Taken together,
there has been built up from these sites a pottery sequence extending
