hot-bed that is in a pretty strong state of fermentation, 

 and afterwards transferred to one that is larger and of 

 more moderate warmth. In general the plants are 

 subsequently kept in flower-pots, and are placed near 

 the green-house plants, or perhaps in the green-house, 

 the shelves of which they may thus decorate, while the 

 proper inhabitants are abroad. Here too, if properly 

 attended to in regard to watering, they will ripen their 

 aeeds, which they seldom do in our climate without

 ance on the back shelves of a hot-house. 



Biennial Fkrrrrt. 



5S3. Some flowers which are, strictly speaking, hi. 

 enniml, are often cultivated among the annual kinds : 

 Such are the Indian pink, (Diantknt CUmeuiit) ; the 

 Pahua Christi, (Hicamt palm* Chruti) ; and the Sen- 

 sitive plant, (\limota trittittva). Others are always 



treated as biennial plants, being kept in nursery rows 

 on, and planted out the next. Sosae 



for the first season, 



of the most common art Honesty or satin-flower ( LH- 

 *wri0M*a), white and purple flowered ; French Ho. 

 neysuckle (Hedytantm eortmmnrm), red and white; 

 Yellow Homed Poppy (Gland** AriMsst); tree-prim- 

 rose, several speoes, ItVMMM **.*</, & c .) ; and 



of different kinds (Irrixucmm), particularly 

 the Moth-mullein (f. Umlturia), yeUow and white 



irori. 



work. 524. In forming a piece of rock-work, it is found 

 very useful to have at least the two or three outward 

 lajeis of stones composed of SWOT-SMMM, that is, of 

 such as have long bun exposed to the action of the 

 weather. At the bases of greenstone and basmh hitf* ve- 

 ry suitable masses may generally be found: thoseshould 

 be selected which hare cavities in them, or are unequal 

 on the surface ; keeping in view also that they must he 

 of such shape as to be capable of being piled on each 

 other in a sloping direction without cement If sack 

 weather-worn stones be selected, and mosey earth be 

 used in place of cement, many kind* of fens*, and va. 

 togamooi plants, will be found to thrive, 

 which would not succeed on 



of any kind of rock fresh dug from a quarry. Besides,

 those already mentioned may be added, Erigeron alpi-

 purple Saxifrage (Saxifraga oppositifolia) and double 

 Sengreen, (S. granultita, H. pi.) ; the borage-leaved 

 Mullein ( I'trbascvm Myconi) ; alpine Lychnis (Lychnis 

 eUptnn) ; and different species ot Primula, P. nivalis, 

 intryiiiv.lia, helvetica and marginal*. The basil- leaved 

 Soap wort (Saponaria ocymotdtt) is one of the most 

 beautiful little plants that adorns the flower-garden, 

 and it is peculiarly well suited for rock work. All the 

 smaller species of hardy Stone- crop deserve a place, 

 in particular Sedum album, glaucum, rupestre, aizoon, 

 and aexangulare ; as well as several species of House- 

 leek, especially the cobweb kind, (Sempervivttm orach- 

 sxMdesjas). In small flower gardens, the rock-work 

 is often constructed oil the margin of a little pond for 

 hardy aquatic plants. 



Aquarium. 



525. The ihiin of the pond is generally either cir- Aquarium,

 the siae of the 'neighbouring parterre or lawn, and by 

 the taste of the owner for the cultivation of aquatic 

 plants. If it be wished to have the white and yellow 

 Water-lily ( .VysspAsra a/6a and \upkar Intro) in perfec- 

 tion, it misst be at least three feet deep. If the ground 

 be open, especially if the subsoil be sandy or gravelly, 

 the bottom should be well laid with puddled day, and 

 the sides should also be lined with the same material, 

 in order to prevent the escape of the water. On the 

 margin a kind of small terrace or shelf is formed, im- 

 mersed only a few inches under water, and commonly 

 laid with channel ; on this are placed pots containing 

 various marsh plains, such aa the Marsh Calla, (Call* 

 jMMtfns.) a native of Lapland and other northern parts 

 of Europe, In some gardens, (as formerly noticed, 

 191') the margin is occupied with the American cr.m.

 than at present. Evrry hanly species is now carefully 

 leJtiisAod, and many new varieties raised from seed, 

 have of late years been introduced. The ramltgui of 

 Lee and Kennedy, of 1 lamaeersmitb, enumerate* no 

 fewer than 315 varieties ; but the nsttMS are not dis- 

 tinguished. Many of the finest variotiM have been beau- 

 tifully figured by Miss Lawrence, in her splendid col-

 be procured. Still better plants however may lie |>re-
