WRACK, TANG, OR JUST
PLAIN SEAWEED
Jim Bennett describes an
Irish Industry
IT WAS ON THE SEASHORE
that man found his first
foothold in Ireland. Out
of sheer necessity he
had to live by the sea,
gathering cockles and
mussels, digging for
bait to enable him to
catch fish.
During the long hard
winters, and in the late
spring, when fodder for
the animals became
scarce, the shore
dwellers would bring the
cattle, sheep and horses
down to the beach where
they could find edible
seaweed as a substitute.
The Scottish farmers who settled in County Down
at the time of the
Plantation found that
their sheep throve on
this diet and kept fat
all winter, where other
animals, on a normal
diet, would fail.

It has since been
proved, by controlled
experiments, that for
animals, the food value
of the knob wrack,
Ascophyllum Nodosum,
which grows near the
high tide mark, is
almost equal to that of
fresh meadow hay, yet
nowadays this valuable
natural resource is
almost completely
neglected as an animal
food.
Certain Species of
seaweed are still
gathered for human
consumption: Chondrus’
Crispus (Careageen, or
Irish moss), Porphyra,
known as sloke, or
layer, and Rhodymenia
palmata, perhaps the
most popular, which is
sold as Dulse. Apart
from the deliciously
flavored Dulse, which is
eaten raw, they can all
be cooked and are
usually served boiled
with potatoes.
Much of the Dulse sold
in seaside resorts in
Northern Ireland comes
from a little village in
County Down called
Ballywalter. A man there
has been collecting the
weed from the rocks a
few miles off-shore for
the past sixty years.
Now a sprightly seventy-
two, during the summer
he still goes off at
low-tide in his little
outboard motor-boat,
taking a friend along to
help him cut the
Rhodymenia which grows
on the rocks.
Very often he sets out
at four or five o’clock
in the morning in order
to catch the tide.
Later, he makes a second
trip during low tide in
the afternoon, hard work
indeed for a man well
past retiring age; yet
he told me recently that
he has never had
rheumatism despite the
cold, damp nature of his
work. The bout of
influenza he had last
year was the first
illness he can ever
remember. It shocked him
so much that he thought
the work must be getting
too much for him and he
almost gave it up.
However, he has
recovered from that
depression; and he was
soon hard at work again.
The SEAWEED is carried
ashore in sacks and then
laid out and stacked to
let the surplus sea
water drain away. Next,
it is spread out on the
stony foreshore, or
along the harbour wall,
to dry completely, which
takes from two to six
hours, according to the
weather conditions. The
dry Dulse is loaded into
sacks and sent to
Belfast, where it is
packed into small paper
bags for distribution
round the resorts.
During the busy tourist
season it is just as
common to see people
walking along the
streets eating Dulse as
sweets, potato crisps or
ices. One traditional
place for the sale of
Dulse is the Auld Lammas
Fair at Ballycastle in
County Antrim. This
started as a hiring fair
at which farm servants
used to be taken on for
a year by their masters.
There were the usual
attractions of a country
fair, with gay stalls
and peepshows, but two
of its essentials were
and still are, at the
present day Dulse and
‘Yellow Man.’ The latter
is a kind of toffee,
bright yellow in colour.
There is a well known
Irish song about a young
man taking his Mary Anne
to the Lammas Fair at
Ballycastle and treating
her to Dulse and Yellow
Man.

Besides being used for
food, seaweed has long
been known as a
fertiliser. In coastal
areas of lreland and
Wales, in the Isles of
Scilly and, doubtless,
elsewhere, it is still
used as such. The lanes,
between their stone
walls, which zig-zig
down to the sea Shore,
used to be known as
wrack roads and fields
near the shore always
had a gate giving direct
access to the sea. In
some little bays, where
the driftweed was known
to collect, the Wrack
Harvest was a time of
merry making and noisy
jollification.
It might also sometimes.
develop into a time of
squabbling and fighting,
over the distribution of
rights to collect in
particular areas. Very
often these were
regulated by some
complicated system. In
places, for instance,
weed beds were allocated
in strips to different
farmers, usually in
proportion to the size
of their farm holdings,
and boulders used as
boundary marks are still
to be seen.
There was a time when
seaweed was so vital to
the success of the
potato crop that a
seaweed farm was
established in County
Down. This remarkable
place was at the mouth
if Carlingford Lough, in
Mill Bay, where, at low
tide, a large area of
mud and sand was
exposed.
The wrack beds were
half-acre rectangles,
set with rows if
boulders, and they
became so valuable that
farmers would pay up to
£10 for one bed; more,
indeed, than he paid for
the land on to which he
spread the seaweed-fertiliser.
One farmer was reported
to have sold his wrack
bed for £145!
Ideally, each farmer
held three beds, one
close inshore for the
knob wrack, one a little
farther out for the
bladder wrack, and one
out in the deep water,
for lazy wrack, which,
being always covered
with sea water, grew
much faster than the
others.
The crop was harvested
between March and June
with knives and sickles.
The reapers, who worked
bare-footed, had also to
reset the heavy boundary
marks if the had become
submerged in sand, as
some times happened. The
sand and mud were too
soft to allow carts to
come in and draw the
weed away, so it was
made into rafts and
floated ashore with the
tide.
In recent times, a Royal
Air Force pilot who flew
over the wrack beds
reported that he had
spotted submerged farms,
or what seemed to of
been little farms marked
out by boulders,
stretching away into the
sea.
PERHAPS the most
profitable way if
exploiting seaweed lay
in the production of
kelp, by burning the
species known as
Laminaria. This practice
continued down to recent
times. It was big
business among shore
dwellers in the
eighteenth century as
kelp was then in demand
for use in the
manufacture of soap,
glass and bleaching
material.

Drying Dulse On The Peir
The thick, tangled weed
was either thrown up by
the winter storms, or
cut, at low tide, by men
using knives strapped on
to long handles up to
twenty feet in length,
so that they could reach
the best weeds which
grew in deep water. The
weeds were dragged
ashore and dried over
low stone walls, then
ricked and thatched in
the seem way as hay.
On dry summer days the
weed was burnt in a kelp
kiln, which was simply a
narrow rectangle of
stones, open at both
ends. In this the kelp
would burn for several
hours, fresh weed being
fed in a little it a
time. It took about
sixty tons of seaweed to
produce one ton of kelp
- another reason why
kelp was so precious.
In the 1750s the rents
were paid in kelp in one
area of West Donegal.
Any surplus that
remained after the
landlord’s demands had
been met was bartered
for the luxuries of
tobacco and spirits.
THE Ashes, or kelp, of
seaweed had some kind of
preservative property: a
book by Martin Martin on
the Western Isles if
Scotland tells how, at
the end of the
seventeenth century,
seals, fish and sea fowl
we’re found preserved in
these ashes. It was also
possible to preserve
cheese by lapping it in
tang, to use the old
Norsemen’s word for sea
wrack by which it a
still sometimes known in
Ireland.
One other further
unorthodox use made of
seaweed. Smugglers used
to hide contraband under
the’ great cart-loads of
wrack being drawn away
for fertiliser, an ideal
way of taking the goods
inland after they had
arrived at the coast.
