to preserve an even temperature. Ifpos- j 
sible a trickle of w^ater should pass from 
one to another, but if draw^n water must 
be used for refilling, it should first stand | 
in the sun to get warm. Sunk thus in i 
a grass plot, a pretty collection may be 
enjoyed, and frost kept out in winter by 
a covering of boards, overlaid with straw 
and mats whenever necessary. Tanks 
may be built to suit any conditions, the 
great point being to avoid overcrowding 
a small space. The yellow kinds are too 
strong for this way of growing, save 
teti^agona he ho la — a little gem with pale 
yellow flowers and a long season. Plants j 
of the Laydekej^igvou^ are all of medium 
growth, free in flower, and rich in colour 
which deepens from day to day ; these 
kinds, with a few of the odorata section 
such as odo7^ata alba^ alba jni7i07^^ rosea^ 
and lucida^ and the beautiful caroli?ii~ 
ana^ with all the forms of N. tetragoiia^ 
are the best for tub-culture. 
The kinds vary as to ' 
Times of Flower. , . , : ^ \ 
earnness and length

of season. Among the earliest are Laj- 
dekeri 7'osea and lilacea^ and ca7^oli7ii- 
a7ia pe7^fecta,^ all of which sometimes 
show flower by the end of May. Lay- 
deke7^i 7'osea not only begins early, but i 
keeps in flower all summer and as late ! 
as any in autumn, and the newer kind, 
N. colossea., so well shown in our en- 
graving, is almost as good in this way j 
and quite one of the best for eflect [ 
through a long season. The Swedish 
Water- Lily (7V^. alba 7^osed) is also among j 
the first, but is not free in flower and 
dies away early. Ellisia7ia .^aurora .,2inA i 
A7id7^ea77a^ are all early when well estab- 
lished, and closely followed by ^/(9r/oj<3',

lucida.^fulva.^ and the forms of N, Mar- 
liacea. The old white Water- Lily {N. 
alba) is two or three weeks behind the 
earlier hybrids, showing again in length 
of season which is yet more pronounced 
in the autumn. It is the end of June 
before the forms of N. odorata are much 
seen, and odo7^ata sitlphtcrea often waits 
for July, but when once started, this 
class flowers well into the autumn with 
such kinds as JLaydeke7^i 7^osea.^ pygmcea 
hehola^ and a fine new cross known as 
B7^akeleyi 7'osea.^ all of which keep on 
into October in a fine season. 
The colours not only vary 
somewhat according to 
season — whether early, full, or late — 
but also as to its dull or sunny character, 
while kinds such as au7^07^a and Lay- 
dekeri vary from day to day, and upon 
others like Ma7diacea albida the nature 
of the soil has a marked eflect. In this 
way such kinds as the Ma7diacce group 
grow paler from the first day, while all 
the Laydeke7^i group deepen with age. 
The best dark Lilies are perhaps F7^oe- 
beli^ sa7igiiinea^ and the lovely IVilliafn 
Falco7ie7^.^ though fulge77S^ pmpwata^ 
and atropU7^pirrea are all good, and, 
though free in bloom spread so slowly 
that they may remain untouched for 
several years. The American variety, 
Jajnes B7ydo7i.^ must also be classed with 
the best new sorts. Shades of orange 
deepening to brick-red are seen in fuha^ 
aurora.^ ^I{obi7iso7iij and Aftdreafia, the 
two last coming very near ; AndreaTia 
is a little the larger. Among pink 
^ow^x^ carolinia7ia perfecta is truly near 
perfection ; William Doogue., odorata
