day would Jiapel all lUmp, and inaure a circulation of air. As 

 alreai'y stated, wlian one house is miiJe a flower-houso, the 

 pbnts' requiring the higbeit temperature should be kept at 

 one end, and no air given there. whiUt air should ho admitted 

 close to such planta iis Oineniriiis and Primulas. In common 

 greenhoasos foiced plunts bhould bo treated in the same way, at 

 least until they are Imr.lened to the atmosphere in which they 

 are placed. in mere average-tomperatured greenhouses hard- 

 wooded plants, as Kcnnedyas, Boroiiias, Hoveas, Leschemiul- 

 tias, Crowea;). and the most teuder Pimeleas require a closer and 

 warmer atmosphere, and more direct li'.;ht, and less direct air 

 comin;^ at once upon them, than would be agreeable to .Acacias, 

 Cytisu"s, and soUwooded plants, as Pelargoniums and Cinera- 

 ria.'!, and the general run of Heaths. One reason why a col- 

 lection of Cape Heaths is best grown in a house by itself, is 

 that they require a very free circulation of air, even if not 

 much above the freezing-point, which circulation at that tem- 

 perature would soon be fatal to a Crowea or a Boronia. Many 

 a fine hardwooded plant from Australasia has been destroyed 

 from standing just behind an opening for air in front of a 

 house in cold weather, when hardier plants would even have 

 enjoyed the draught. We arc (jnite well aware that such plants 

 in their natural habitats often pass unharmed tlirough a de- 

 gree of cold to which they would be rarely subject in our green- 

 Louses ; but we must not forget that the fierce cloudless sun 

 in such climates in summer gives a hardness and induration to 

 the wood which it can hardly acquire under any circumstances 

 in our more moist and clouded climate. Besides, we are too 

 often led to forget the effects of a draught of cold air. It is 

 a very different thing from exposure to the cold without the 

 draught. We have known instances of delicate young ladies, 

 aye, and young gentlemen too, who would pass from a heated 

 ball-room, and with little more than a loose shawl or mantle 

 in addition to ball-room clothing, and traverse the gardens and 

 parterres of an evening, and with scarcely a perceptibly injurious 

 effect ; but, alas ! we know of instances under such circumstances 

 in which, when oppressed with the heat of the rooms, sitting 

 for fifteen or thirty minutes iu the a;creeable coolness from the 

 draught of an open window, has but too surely left its mark 

 in the hectic consumption and the untimely death. 



Had we again the chance of growing a good collection of the 

 hardwooded tenderer Australasian plants, except in extremely 

 mild weather they should never have air directly beating upon 

 them from the front of the house, unless it was heated before 

 it reached them. They would have all thai would be necessary 

 for them from top air alone. As a general rule, in ordinary cir- 

 cumstances, with all such tender hardwooded plants front air 

 should be given sparingly in winter. A very slight opening 

 at the apex wUl in genersil soon set all the air in a house in 

 motion, and the heated air that escapes will heat and moisten 

 the heavier and colder air as it passes through it. Some time 

 ago we were asked to look at some nice cottages for labouring 

 men. Strange, the windows that did not open from top to 

 bottom were in two halves, the upper half a fixture, the lower 

 half lifting up so as to give what air was wanted about 2{ feet 

 from the iioor. The hundred or so of windows, we are glad to 

 say, were altered, so that the upper sash should pull down. 

 An inch even in a cold day would soon change the atmosphere 

 of a room, and if a person were at a respectable distance, he 

 would enjoy the fresh air without being cooled by it. The 

 throwing up of the lower sash admitted the cold air from with- 

 out to mix at once with nearly the coldest air of the room. 

 Hence for all glass houses we luuk upon top air in ordinary cir- 

 cumstances as more suitable, and especially in winter, than 

 front air, which shotild always be admitted with care and cau- 

 tion. If the stimulus from expansion from heat is regulated 

 by the presence of bright light, the whole theory and practice 

 of ventilation will be reduced to its simplest proportions ; 

 unless in extreme cases, sunlight, and sun heat along with the 

 light, will not make plants weakly or diseased. In such favour- 

 able sunlight the chief danger to be guarded against is 

 scorching from the want of early air-giving; and make sure 

 if a rather high temperature is reached, that it rises gradually, 

 and after air has been given. The giving a little early is of 

 more importance in every way than giving much at a time, and 

 often when too late. Went on potting, iSsc, as detailed in pre- 

 -vious weeks' notices. — B. F.

TO CORRESPONDENTS. 



•.• We request that no one will write privately to the depart- 

 mental writers of the "Journal of Horticulture, Cottage 

 Gardener, and Country Gentleman." By so doing they 

 are subjected to unjustifiable trouble and expense. All 

 communications should therefore be addressed solely to 

 Tlte EdiUm of the Journal of Horticulture, <£c., 171, Fleet 

 Street, London, E.C. 

 We also request that correspondents will not mix up on the 

 same sheet questions relating to Gardening and those on 

 Poultry and Bee subjects, if they expect to get them an- 

 swered promptly and conveniently, but write them on 

 separate communications. Also never to send more than 

 two or three questions at once. 



N^. Many questions must remain unanswered nntil next 



week. 

 Febs Mastjal (G. G.).— There is no enlarged lorm. 

 Meait Potatoes.— <J. P. will be greatly obliged by '■ W, Boss" stating 

 when and how Ue applies the alltalies he recommend-s. Should they be 

 spread upon the soil and dug into the earth some time before planting 

 the Potatoes, or should this be done just at the time of planting ? 



ViKE-BORDEB— RlBBoN-notiDF.B (.T. T. IT.).— We woulrt do nothing to 

 your border. Leave the thatched covering, it will bo all right. Where 

 rabbits are troublesome a Geranium-bordar would look vury wcU in four 

 line", with the sorts vou name planted thus— Golden Chain. Flower of the 

 Dav Tom Thumb, and Madame Vaucbcr and Maneles'. miied. for the back 

 row.' If Flower of the l>oy were small, and Golden Chain were large, wc 

 would transpose them, placing Flower of the Day in frout. 



RiBBoN-BORDKR (IT. C. F.).—Ot TonT two arrangcmcnU we prefer this 

 —1st row next the grass, Ccrasliuni tnmentosum. white ; and. blue Lobelia 

 dotted with Geranium Cloth of G..ld. blue and yellow: 3rd. Flower of the 

 Day Geranium, scarlet and white; 4th, Christine, pink: 5th, SUUa 

 Nosegay, scarlet ; 8tb, yellow C'leeoUrU ; 7th, .Agenilmn. alternately 

 with Zelinda DahUa, blue and purple. This plan Would Lok very well it 

 the flowers were taken off Flower of the Doy Geranium. For the seventh 

 row AKcratum or Zelinda Dahlia, would be more easily nianased if only 

 one' of them were used lor the row. The same remark will apply to the 

 second plan. We like the first the better. 



Books (J5. S. B.).— For the management of plants in the greenhouse. 

 4c Keane's ■In-door Gardening;" for plants in the garden. Keane's 

 "Out-door Gardening' will suit von. Yon may have either of Uiem free 

 by post from our office liy enclosing twenty Btanips with yonr addreu, or 

 forty stomps for the two. 



Orchtos ym a North House (S. t.).— When speaking of those at 

 Mr. Low's nursery, I mentioned them as instances of conlhouse growing, 

 so that I cannot say whether such would snit " S. L.'s " store. He might, 

 however, try" Lvcaste skinneri, Barkeria ^pectnhilis, sophronitis grandi- 

 flnra, Odontoglossum gi-ande. gloriosnm, &c. If ho apply to Messrs. 

 Bnckhon.4e. of York, Ibcy would send him his catalogue, in which he wUl 

 obtain a great deal of information, well and clearly pat.— D., Deal.
