botany is; you search in vain for curious forms over which you trod
every day in crossing flats which seemed to you utterly ugly and
uninteresting; but which the good God was watching as carefully as
He did the pleasant hills inland: perhaps even more carefully; for
the uplands He has completed; and handed over to man; that he may
dress and keep them: but the tide…flats below are still
unfinished; dry land in the process of creation; to which every
tide is adding the elements of fertility; which shall grow food;
perhaps in some future state of our planet; for generations yet
unborn。
But to return to the water…world; and to dredging; which of all
sea…side pursuits is perhaps the most pleasant; combining as it
does fine weather sailing with the discovery of new objects; to
which; after all; the waifs and strays of the beach; whether
〃flotsom jetsom; or lagand;〃 as the old Admiralty laws define them;
are few and poor。 I say particularly fine weather sailing; for a
swell; which makes the dredge leap along the bottom; instead of
scraping steadily; is as fatal to sport as it is to some people's
comfort。 But dredging; if you use a pleasure boat and the small
naturalist's dredge; is an amusement in which ladies; if they will;
may share; and which will increase; and not interfere with; the
amusements of a water…party。
The naturalist's dredge; of which Mr。 Gosse's 〃Aquarium〃 gives a
detailed account; should differ from the common oyster dredge in
being smaller; certainly not more than four feet across the mouth;
and instead of having but one iron scraping…lip like the oyster
dredge; it should have two; one above and one below; so that it
will work equally well on whichsoever side it falls; or how often
soever it may be turned over by rough ground。 The bag…net should
be of strong spunyarn; or (still better) of hide 〃such as those
hides of the wild cattle of the Pampas; which the tobacconists
receive from South America;〃 cut into thongs; and netted close。 It
should be loosely laced together with a thong at the tail edge in
order to be opened easily; when brought on board; without canting
the net over; and pouring the contents roughly out through the
mouth。 The dragging…rope should be strong; and at least three
times as long as the perpendicular depth of the water in which you
are working; if; indeed; there is much breeze; or any swell at all;
still more line should be veered out。 The inboard end should be
made fast somewhere in the stern sheets; the dredge hove to
windward; the boat put before the wind; and you may then amuse
yourself as you will for the next quarter of an hour; provided that
you have got ready various wide…mouthed bottles for the more
delicate monsters; and a couple of buckets; to receive the large
lumps of oysters and serpulae which you will probably bring to the
surface。
As for a dredging ground; one may be found; I suppose; off every
watering…place。 The most fertile spots are in rough ground; in not
less than five fathoms water。 The deeper the water; the rarer and
more interesting will the animals generally be: but a greater
depth than fifteen fathoms is not easily reached on this side of
Plymouth; and; on the whole; the beginner will find enough in seven
or eight fathoms to stock an aquarium rivalling any of those in the
〃Tank…house〃 at the Zoological Gardens。
In general; the south coast of England; to the eastward of
Portland; affords bad dredging ground。 The friable cliffs; of
comparatively recent formations; keep the sea shallow; and the
bottom smooth and bare; by the vast deposits of sand and gravel。
Yet round the Isle of Wight; especially at the back of the Needles;
there ought to be fertile spots; and Weymouth; according to Mr。
Gosse and other well…known naturalists; is a very garden of Nereus。
Torbay; as may well be supposed; is an admirable dredging spot;
perhaps its two best points are round the isolated Thatcher and
Oare…rock; and from the mouth of Brixham harbour to Berry Head;
along which last line; for perhaps three hundred years; the decks
of all Brixham trawlers have been washed down ere running into
harbour; and the sea…bottom thus stored with treasures scraped up
from deeper water in every direction for miles and miles。
Hastings is; I fear; but a poor spot for dredging。 Its friable
cliffs and strong tides produce a changeable and barren sea…floor。
Yet the immense quantities of Flustra thrown up after a storm
indicate dredging ground at no great distance outside; its rocks;
uninteresting as they are compared with our Devonians; have yielded
to the industry and science of M。 Tumanowicz a vast number of sea…
weeds and sponges。 Those three curious polypes; Valkeria cuscuta
(Plate I。 fig。 3); Notamia Bursaria; and Serialaria Lendigera;
abound within tide…marks; and as the place is so much visited by
Londoners; it may be worth while to give a few hints as to what
might be done; by anyone whose curiosity has been excited by the
salt…water tanks of the Zoological Gardens and the Crystal Palace。
An hour or two's dredging round the rocks to the eastward; would
probably yield many delicate and brilliant little fishes; Gobies;
brilliant Labri; blue; yellow; and orange; with tiny rabbit mouths;
and powerful protruding teeth; pipe fishes (Syngnathi) (25) with
strange snipe…bills (which they cannot open) and snake…like bodies;
small cuttlefish (Sepiolae) of a white jelly mottled with brilliant
metallic hues; with a ring of suckered arms round their tiny
parrots' beaks; who; put into a jar; will hover and dart in the
water; as the skylark does in air; by rapid winnowings of their
glassy side…fins; while they watch you with bright lizard…eyes; the
whole animal being a combination of the vertebrate and the mollusc;
so utterly fantastic and abnormal; that (had not the family been
amongst the commonest; from the earliest geological epochs) it
would have seemed; to man's deductive intellect; a form almost as
impossible as the mermaid; far more impossible than the sea…
serpent。 These; and perhaps a few handsome sea…slugs and bivalve
shells; you will be pretty sure to find: perhaps a great deal
more。
Meanwhile; without dredging; you may find a good deal on the shore。
In the spring Doris bilineata comes to the rocks in thousands; to
lay its strange white furbelows of spawn upon their overhanging
edges。 Eolides of extraordinary beauty haunt the same spots。 The
great Eolis papillosa; of a delicate French grey; Eolis pellucida
(?) (Plate X。 fig。 4); in which each papilla on the back is
beautifully coloured with a streak of pink; and tipped with iron
blue; and a most fantastical yellow little creature; so covered
with plumes and tentacles that the body is invisible; which I
believe to be the Idalia aspersa of Alder and Hancock。
At the bottom of the rock pools; behind St。 Leonard's baths; may be
found hundreds of the snipe's feather Anemone (Sagartia
troglodytes); of every line; from the common brown and grey snipe's
feather kind; to the white…horned Hesperus; the orange…horned
Aurora; and a rich lilac and crimson variety; which does not seem
to agree with either the Lilacinia or Rubicunda of Gosse。 A more
beautiful living bouquet could hardly be seen; than might be made
of the varieties of this single species; from this one place。
On the outside sands between the end of the Marina and the Martello
tower; you may find; at very low tides; great numbers of a sand…
tube; about three inches long; standing up out of the sand。 I do
not mean the tubes of the Terebella; so common in all sands; which
are somewhat flexible; and have their upper end fringed with a
ragged ring of sandy arms: those I speak of are straight and
stiff; and ending in a point upward。 Draw them out of the sand …
they will offer some resistance … and put them into a vase of
water; you will see the worm inside expand two delicate golden
combs; just like old…fashioned back…hair combs; of a metallic
lustre; which will astonish you。 With these combs the worm seems
to burrow head downward into the sand; but whether he always
remains in that attitude I cannot say。 His name is Pectinaria
Belgica。 He is an Annelid; or true worm; connected with the
Serpulea and Sabellae of which I have spoken already; and holds
himself in his case like them; by hooks and bristles set on each
ring of his body。 In confinement he will probably come out of his
case and die; when you may dissect him at your leisure; and learn a
great deal more about him thereby than (I am sorry to say) I know。
But if you have courage to run out fifteen or twenty miles to the
Diamond; you may find really rare and valuable animals。 There is a
risk; of course; of being blown over to the coast of France; by a
change of wind; th
