apply St。 Paul's words by no means irreverently or fancifully�察 �which do
but gender strife�察─ � not in these pedantries is that moral training to be
found�察 �for which we have been lauding the study of Natural History�此�
but in healthful walks and voyages out of doors�察 �and in careful and
patient watching of the living animals and plants at home�察 �with an
observation sharpened by practice�察�and a temper calmed by the continual
practice of the naturalist's first virtues ´ patience and perseverance。
Practical directions for forming an ;Aquarium; may be found in Mr。
Gosse's book bearing that name�察 �at pp。 101�察 �255�察 �ET SEQ。�察 �and those
who wish to carry out the notion thoroughly�察�cannot do better than buy
his book�察�and take their choice of the many different forms of vase�察�with
rockwork�察�fountains�察�and other pretty devices which he describes。
But the many�察 �even if they have Mr。 Gosse's book�察 �will be rather
inclined to begin with a small attempt�察 �especially as they are probably
half sceptical of the possibility of keeping sea´animals inland without
changing the water。 A few simple directions�察 �therefore�察�will not come
amiss here。 They shall be such as anyone can put into practice�察 �who
goes down to stay in a lodging´house at the most cockney of watering´

places。
Buy at any glass´shop a cylindrical glass jar�察 �some six inches in
diameter and ten high�察�which will cost you from three to four shillings�察�
wash it clean�察 �and fill it with clean salt´water�察 �dipped out of any pool
among the rocks�察�only looking first to see that there is no dead fish or
other evil matter in the said pool�察�and that no stream from the land runs
into it。 If you choose to take the trouble to dip up the water over a
boat's side�察�so much the better。
So much for your vase�察�now to stock it。
Go down at low spring´tide to the nearest ledge of rocks�察�and with a
hammer and chisel chip off a few pieces of stone covered with growing
sea´weed。 Avoid the common and coarser kinds ��fuci�� which cover the
surface of the rocks�察 �for they give out under water a slime which will
foul your tank�此 �but choose the more delicate species which fringe the
edges of every pool at low´water mark�察 �the pink coralline�察 �the dark
purple ragged dulse ��Rhodymenia���察�the Carrageen moss ��Chondrus���察�and
above all�察�the commonest of all�察�the delicate green Ulva�察�which you will
see growing everywhere in wrinkled fan´shaped sheets�察 �as thin as the
finest silver´paper。 The smallest bits of stone are sufficient�察 �provided
the sea´weeds have hold of them�察�for they have no real roots�察�but adhere
by a small disc�察�deriving no nourishment from the rock�察�but only from
the water。 Take care�察�meanwhile�察�that there be as little as possible on
the stone�察 �beside the weed itself。 Especially scrape off any small
sponges�察�and see that no worms have made their twining tubes of sand
among the weed´stems�察�if they have�察�drag them out�察�for they will surely
die�察�and as surely spoil all by sulphuretted hydrogen�察�blackness�察�and evil
smells。
Put your weeds into your tank�察�and settle them at the bottom�察�which
last�察�some say�察�should be covered with a layer of pebbles�此 �but let the
beginner leave it as bare as possible�察�for the pebbles only tempt cross´
grained annelids to crawl under them�察 �die�察 �and spoil all by decaying�此�
whereas if the bottom of the vase is bare�察�you can see a sickly or dead
inhabitant at once�察�and take him out ��which you must do�� instantly。 Let
your weeds stand quietly in the vase a day or two before you put in any

live animals�察 �and even then�察 �do not put any in if the water does not
appear perfectly clear�此 �but lift out the weeds�察�and renew the water ere
you replace them。
This is Mr。 Gosse's method。 But Mr。 Lloyd�察�in his ;Handbook to the
Crystal Palace Aquarium�察─�advises that no weed should be put into the
tank。 ;It is better�察─�he says�察 �to depend only on those which gradually
and naturally appear on the rocks of the aquarium by the action of light�察�
and which answer every chemical purpose。; I should advise anyone
intending to set up an aquarium�察�however small�察�to study what Mr。 Lloyd
says on this matter in pp。 17´19�察 �and also in page 30�察�of his pamphlet�察�
and also to go to the Crystal Palace Aquarium�察�and there see for himself
the many beautiful species of sea´weeds which have appeared
spontaneously in the tanks from unsuspected spores floating in the sea´
water。 On the other hand�察�Mr。 Lloyd lays much stress on the necessity
of a �r ating the water�察�by keeping it in perpetual motion�察�a process not
easy to be carried out in small aquaria�察�at least to that perfection which
has been attained at the Crystal Palace�察 �where the water is kept in
continual circulation by steam´power。 For a jar´aquarium�察 �it will be
enough to drive fresh air through the water every day�察 �by means of a
syringe。
Now for the live stock。 In the crannies of every rock you will find
sea´anemones ��Actiniae���察 �and a dozen of these only will be enough to
convert your little vase into the most brilliant of living flower´gardens。
There they hang upon the under side of the ledges�察 �apparently mere
rounded lumps of jelly�此 �one is of dark purple dotted with green�察�
another of a rich chocolate�察�another of a delicate olive�察�another sienna´
yellow�察�another all but white。 Take them from their rock�察�you can do it
easily by slipping under them your finger´nail�察�or the edge of a pewter
spoon。 Take care to tear the sucking base as little as possible ��though a
small rent they will darn for themselves in a few days�察 �easily enough�察�
and drop them into a basket of wet sea´weed�察�when you get home turn
them into a dish full of water and leave them for the night�察 �and go to
look at them to´morrow。 What a change� �The dull lumps of jelly
have taken root and flowered during the night�察 �and your dish is filled

into a hundred´petalled flower�察 �crimson�察 �pink�察 �purple�察�or orange�察 �touch
one�察�and it shrinks together like a sensitive plant�察 �displaying at the root
of the petals a ring of brilliant turquoise beads。 That is the commonest
of all the Actiniae ��Mesembryanthemum���察�you may have him when and
where you will�此 �but if you will search those rocks somewhat closer�察�
you will find even more gorgeous species than him。 See in that pool
some dozen large ones�察�in full bloom�察�and quite six inches across�察�some
of them。 If their cousins whom we found just now were like
Chrysanthemums�察 �these are like quilled Dahlias。 Their arms are stouter
and shorter in proportion than those of the last species�察�but their colour is
equally brilliant。 One is a brilliant blood´red�察 �another a delicate sea´
blue striped with pink�察�but most have the disc and the innumerable arms
striped and ringed with various shades of grey and brown。 Shall we get
them�拭 �By
