striped and ringed with various shades of grey and brown。 Shall we get
them�拭 �By all means if we can。 Touch one。 Where is he now�拭�
Gone�拭 �Vanished into air�察�or into stone�拭 �Not quite。 You see that knot
of sand and broken shell lying on the rock�察�where your Dahlia was one
moment ago。 Touch it�察�and you will find it leathery and elastic。 That
is all which remains of the live Dahlia。 Never mind�察 �get your finger
into the crack under him�察 �work him gently but firmly out�察�and take him
home�察�and he will be as happy and as gorgeous as ever to´morrow。
Let your Actiniae stand for a day or two in the dish�察 �and then�察�
picking out the liveliest and handsomest�察 �detach them once more from
their hold�察�drop them into your vase�察�right them with a bit of stick�察�so
that the sucking base is downwards�察 �and leave them to themselves
thenceforth。
These two species ��Mesembryanthemum and Crassicornis�� are quite
beautiful enough to give a beginner amusement�此 �but there are two
others which are not uncommon�察�and of such exceeding loveliness�察 �that
it is worth while to take a little trouble to get them。 The one is
Dianthus�察 �which I have already mentioned�察 �the other Bellis�察 �the sea´
daisy�察�of which there is an excellent description and plates in Mr。 Gosse's
;Rambles in Devon�察─�pp。 24 to 32。
It is common at Ilfracombe�察 �and at Torquay�察 �and indeed everywhere
90

Glaucus/or The Wonders of the Shore
where there are cracks and small holes in limestone or slate rock。 In
these holes it fixes its base�察�and expands its delicate brown´ grey star´like
flowers on the surface�此 �but it must be chipped out with hammer and
chisel�察 �at the expense of much dirt and patience�察 �for the moment it is
touched it contracts deep into the rock�察�and all that is left of the daisy
flower�察�some two or three inches across�察�is a blue knot of half the size of
a marble。 But it will expand again�察�after a day or two of captivity�察�and
will repay all the trouble which it has cost。 Troglodytes may be found�察�
as I have said already�察�in hundreds at Hastings�察�in similar situations to
that of Bellis�察 �its only token�察 �when the tide is down�察 �being a round
dimple in the muddy sand which firs the lower cracks of rocks。
But you will want more than these anemones�察 �both for your own
amusement�察�and for the health of your tank。 Microscopic animals will
breed�察�and will also die�察�and you need for them some such scavenger as
our poor friend Squinado�察 �to whom you were introduced a few pages
back。 Turn�察�then�察�a few stones which lie piled on each other at extreme
low´water mark�察�and five minutes' search will give you the very animal
you want�察 � a little crab�察�of a dingy russet above�察�and on the under side
like smooth porcelain。 His back is quite flat�察 �and so are his large
angular fringed claws�察 �which�察 �when he folds them up�察 �lie in the same
plane with his shell�察�and fit neatly into its edges。 Compact little rogue
that he is�察�made especially for sidling in and out of cracks and crannies�察�
he carries with him such an apparatus of combs and brushes as Isidor
or Floris never dreamed of�察�with which he sweeps out of the sea´ water at
every moment shoals of minute animalcules�察 �and sucks them into his
tiny mouth。 Mr。 Gosse will tell you more of this marvel�察 �in his
;Aquarium�察─�p。 48。
Next�察 �your sea´weeds�察 �if they thrive as they ought to do�察 �will sow
their minute spores in millions around them�察�and these�察�as they vegetate�察�
will form a green film on the inside of the glass�察 �spoiling your prospect�此�
you may rub it off for yourself�察�if you will�察�with a rag fastened to a stick�察�
but if you wish at once to save yourself trouble�察 �and to see how all
emergencies in nature are provided for�察 �you will set three or four live
shells to do it for you�察�and to keep your sub´aqueous lawn close mown。

That last word is no figure of speech。 Look among the beds of sea´
weed for a few of the bright yellow or green sea´snails ��Nerita���察 �or
Conical Tops ��Trochus���察�especially that beautiful pink one spotted with
brown ��Ziziphinus���察�which you are sure to find about shaded rock´ledges
at dead low tide�察 �and put them into your aquarium。 For the present�察�
they will only nibble the green ulvae�察 �but when the film of young weed
begins to form�察 �you will see it mown off every morning as fast as it
grows�察�in little semicircular sweeps�察�just as if a fairy's scythe had been at
work during the night。
And a scythe has been at work�察 �none other than the tongue of the
little shell´fish�察�a description of its extraordinary mechanism ��too long to
quote here�察 �but which is well worth reading�� may be found in Gosse's
;Aquarium。; ��32��
A prawn or two�察�and a few minute star´fish�察�will make your aquarium
complete�察�though you may add to it endlessly�察�as one glance at the salt´
water tanks of the Zoological Gardens�察 �and the strange and beautiful
forms which they contain�察�will prove to you sufficiently。
You have two more enemies to guard against�察�dust�察�and heat。 If the
surface of the water becomes clogged with dust�察 �the communication
between it and the life´giving oxygen of the air is cut off�察�and then your
animals are liable to die�察�for the very same reason that fish die in a pond
which is long frozen over�察�unless a hole be broken in the ice to admit the
air。 You must guard against this by occasional stirring of the surface�察�or�察�
as I have already said�察�by syringing and by keeping on a cover。 A piece
of muslin tied over will do�察�but a better defence is a plate of glass�察�raised
on wire some half´inch above the edge�察�so as to admit the air。 I am not
sure that a sheet of brown paper laid over the vase is not the best of all�察�
because that�察�by its shade�察�also guards against the next evil�察�which is heat。
Against that you must guard by putting a curtain of muslin or oiled paper
between the vase and the sun�察�if it be very fierce�察�or simply ��for simple
expedients are best�� by laying a handkerchief over it till the heat is past。
But if you leave your vase in a sunny window long enough to let the
water get tepid�察�all is over with your pets。 Half an hour's boiling may
frustrate the care of weeks。 And yet�察�on the other hand�察�light you must

have�察 �and you can hardly have too much。 Some animals certainly
prefer shade�察 �and hide in the darkest crannies�察 �and for them�察 �if your
aquarium is large enough�察�you must provide shade�察�by arranging the bits
of stone into piles and caverns。 But without light�察�your sea´weeds will
neither thrive nor keep the water sweet。 With plenty of light you will
see�察 �to quote Mr。 Gosse once more�察 。�33�� ;thousands of tiny globules
forming on every plant�察 �and even all over the stones�察 �where the infant
vegetation is beginning to grow�察 �and these globules presently rise in
rapid succession to the surface all over the vessel�察�and this process goes
on uninterruptedly as lon
