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
