to indicate Ihnt a morbid slate of the sap is the chief criHse of the honey- 

 dow, for otherwise it would bo difficult to explain the ronson why the use 

 of a KolutioD of common salt in wntcr, applied to tho »oil in which a 

 plant is growing, can prevent a disciise caused by inHcrts. But if wo 

 adn.it that the iiTcffulur action of tho sap is the cause of the disorder, 

 then we can understand that a portion of salt introduced in tho juices of 

 tho plant would naturally havo au influence in correcting any morbid 

 tendency, eitln-r i>revcnting the too rapid secretion of sap. stimulating it 

 in promoting ilrt regular formation, or preserving its fluidity; and that 

 by such a treatment the honeydow may ho entirt-ly prevented wo havo 

 often witnessed when experimontalising with totuUy dilTeront objects. 

 Thus wo havo seen plants of various kind', which have been treated with 

 a weak solution of cummon salt and water, totally escape the honeydew, 

 where trees of tho same kind growing in the same plot of ground not so 

 treated, havo been materially injured by its ravages " 



Hbatinc, a <.'onsi:rvatorv ( 7'. IT.).— One of Hays's middle-sized stoves 

 would keep tho frobt out of tho conservatory, :J!) feet by 9 feet. Wo pre- 

 sume it to be a lean-to. Of course you are aware that you must purchase 



and leaf mould. Begonia Veitchii wo do not know. B. magniflca woald 

 Hur\ive tho winter in a wann greenhouse, the soil being kept dry. 



Proi'aoatino and Wintebino Pelabgonilms (.VoriVc).— The one*Ught 

 frame will not be of any use, as cuttings taken now and put in boxes three- 

 ]>arts lilted with sandy soil, and to the brim with Bhnrp sand, will striko 

 freely out of doors in the full sun, the soil being kept niwist. When cold 

 weather sets in the cuttings may be moved iuthe boxes to the room without 

 fire, and being kept dr>* lud afforded plenty of air they will live through tho 

 winter if taken to a place of safety during severe weather. Just enough 

 water shoulJ bo given them occasionally to keep them from drying up, 

 otherwise they cannot bo kept too dry. The stable, the room, and tho 

 cellar will do for the old plants, but these must be kept from frost, and all 

 decayed leavts and stems should bo pricked ofl* as they appear. Your 

 frame will answer admirably for Calceolaria cuttings if placed in a warm 

 situation and over a bed of good rich soil. Two or three inches of sand 

 m ay bo placed within tho fr.ime, and the cuttings put in early in October, 

 1) inch apart. A good watering should be given, and tho plants should 

 have all tho air puSHible, using the lights only at night and during heavy 



the preparetl fuel. Wo would advise even then that a small gas-pipe ' rains In severe frosts it will bo necessary to cover tho lights with two 



should go from tho top of tho stove. A round or square stove of iron 

 8ay 15 inches wide, and at least oO inches high, with a pipe through the 

 roof, would also suit you, more especially if tlic firo-box stand free of the 

 sides of the stove all round. That, of cour.^e, would burn coke or com- 

 mon cinders. We fear prepared fuel, as an essential, will lessen the use- 

 fulness of stoves that need it, as people are apt to forget such little 

 matters until the frost comes suddenly nud does tho mischief. We con- 

 sider anti-corrosiou paint first-rate for ciimmon purposes ; but wo would 

 nse it chiefly for tho outsidcs of glass houses, us lead paint inside is 

 more easily washed. 



Herbaceods Plants for Bf.ds (C/n/i).— The Evening Primrose ((Eno- 

 thera macrocarpa), makes a flue bed of yellow, and continues long in 

 bloom. Agrostemma ooronaria is also a fine plant for a bed ; it has 

 bright rosy crimson blossoms. A bed of Antirrbinnms is also excellent ; 

 they are of many colours, and look well mixed or in a bed of one colour. 

 Salvia nemorosa, baring silvery foliage and numertms bluisli purple 

 flowers continuing through the summer, is fine for a bed. Delphinium 

 Bellailonna, with sky-bluo flowers, is one of tho very best blue-flowering 

 boddets. Lythrum roseum supcrbum, with rose-coloured blossoms, is 

 tlno for a bed in cp.rly summer, but does not do for autumn. Fuchsia 

 globii-^a is very pretty in abed in autumn, being of a fine scarlet and violet. 

 Sliinulus cupreus does well in rather shady, moist situations, and has 

 hiind-itme yellowish orange flowers. Few plants arc equal to herbaceous 

 Phloxes, which may bo planted one colour in a bed or in mixtures. Py- 

 r«lhrums, of which there are many kinds and colours, arc fine for beds. 

 Pentstcmiius have a fine effect in a bed late in summer and in autumn, 

 and Dianthusbybridus Marie Pare is the best of the white hybrid Pinks for 

 a bed. 



Gladioluses in Pots after Blooming {H. Fni/).—V»'hca tho foliage 

 becomes yellow take up the bulbs, lay them in a dry place, and when dry 

 remove the stalks, and store the roots in dry sand in a cool place after 

 cleaning them. The plants sliould not be much watered after flowering, 

 but must be gradually dried off. 



Wintering Gloxinia Tubers (/(/.ml.— After flowering tho plants 

 should be kept dry, and if the pots are placed on a coul bottom in any 

 house from which frost is excluded, the tubers will ^vj^ter safely. They 

 also keep well iu a cellar until February or March, and may tlien have all 

 tho old soil shaken from the roots, and be fresh potted and placed iu a 

 hotbod. 



Hardiness of LiLini LoNoiFLonrsi (/'//■ "i).~Lilium longiflornm suc- 

 ceeds admirably in a cool pit during the winter if the pot is plunged to 

 tho rim in coal ashes; and it will stand the winter uninjured out of 

 doors if tho pot be plunccd to the rim iu coal ashes in a sheltered situ- 

 ation, and a thin layer of short litter spread over tho surface. 



WcLFENiA CARiNTHiACA CULTURE (M. A. £".).— Tho plants may he 

 potted iu u compost of turfy loam, leaf mould, and sand iu equal parts, 

 tbo pots being well drained, for tho soil must bo kept moist, and good 

 drainage is therefore essential. The plants may bo placnd out of doors 

 in an open but not very sunny situation, and the pots plunged to tlie rim. 

 They should have an abundant supply of water, but the soil should not 

 be kept saturated. The pots may be withdrawn in autumn, and set on 

 ashes or plunged in them iu a cold frame, where they sbould have abun- 

 dance of air, and protection from those frosts succeeding a warnt period, 

 which are the chief evils cultivators of plants from elevated situations 

 have to contend against. To save trouble you may plant them in a 

 sheltered situation out of doors in rich turfy loam, leaf mould, and sand. 

 They will require water frequently during dry weather. 



Pruning Klairii No. 2 Uose ihlem),— This Hose is rather impatient of 

 pruning, and should not be closely cut. Tho old wood should be cut out 

 as well as some of tho shoots, if these are too close together, some of 

 them ha\'ing the ends merely shortened a little, so that a uniform head 

 may be produced. 



Various ( ). — All the Aucubasare perfectly hardy, and Aucubahima 



laiaca will probably hybridise with A. japouica. Dcsmodium racemosum 

 is hai'dy, &ucceediug iu an open situation iu a compost of peat, loam. 



or three mats, and any other covering that may be at hand. You will 

 find full particulars as to the propagation and wintering of bedding Pelar- 

 goniums at page i)7, of No. 2H0, and pago 807, of No. 291, and for tbo pro- 

 pagation of Calceolarias seo No. '2S9, page 271. Tho small purpio plant is 

 Aubrietia dcltoiden, and the Tropxolum one of the many varieties that 

 are raised from seed. 



Strawderrv Forcing (, 4 Younrj Bertinnfrt. — You may take up and pot 

 all the plants of Black Prince and British Queen, but the others named 

 by you we do not consider good kinds lor forcing, end the British Qacca 

 is not a good early forcer; but you lUHy pot Princess Alice Maud freely. 

 Due do Slalakoff forces well. Black Prince is vury good for tho purpose. 

 Tho potting should be done forthwith, the pbmts being abundantly 

 watered and shaded from bright sun until established. If tbo pots bo 

 placed in tbo house iu February the fruit will be ripe in April, and the 

 plants may be cleared out at tho end of tho month. We would advise 

 you to pot last year's runners in preference to old plants, and when you 

 can obtain well-rooted runuers of the current year, by all means pot them, 

 taking them up with a ball. 



Pegging Down China Roses ili. E. L.).—\\l tho shoots of the China 

 Roses may bo pegged down, and doing so will not destroy them, unless 

 the work is so carulcssly performed as to break them. It should be dono 

 gently and by degrees. 



Air-roots on Vine Stems (Idem). — Bad management has nothing to 

 do witn air-roots on the stems of Vines ; they are the result of the roots 

 being iu a cold outside border, whilst the branches are in a warm, moist 

 atmosphere. They are more or less prcseut on all Vines when they be- 

 ' come aged, and aro evidence that the roots are not in a congenial medium- 

 CocKscoMn DA3IPING {W. C). — The Cockscomb sent appears to have 

 suffered from an excess of moisture. Wo think a little more heat and 

 more air would make all right, and we should cci-tainly remove the plants 

 to a cold frame, which you may easily convert into a stove by giving air 

 early in the morning and shutting up early iu tho afternoon. We make 

 no charge for answering questions. 



Proi'agating Achillea clavenn.t: and Acdrietia orxca varieoata. 

 iSubscrihrr). — The Achillea clavenme is a pretty silver-edged plant, and 

 in dry soils nearly as liardv as the Arabis. To make sure wo would 

 take up the pbtnt and divide it into as many pieces as possible, and plant 

 under a hand-light — if in small pots all the better, and give just a 

 little pioteclion in cold weather in winter. Yon will best propagate tho 

 variegated Aubrietia gritca in a similar way ; but cuttings of that, the 

 smallest bits, will fctrike, and now is a good time. The common varieg.ited 

 Arabis we propagate by taking the cuttings iu autumn and winter and in- 

 serting them in an open border with sand along the rows, and put in a 

 few evergreen twigs in severe weathor\ Viola cornuta iseasiiy propagated 

 by cuttings, or taking up a plant and dividing it. Viola lutea is of even 

 a closer hibil— a bright yellow flower, one of the pretty plants Mr. Tyer- 

 man, of the Liverpool Botanic Gardens, has made popular, but which we 

 have lost through tho depredations of rabbits. It is an abundant bloomer.
