the quantity of space heated by the flue. Besides, where a high 

 temperature is required a boiler is more economical than a flue. 



Hot Wateb. — To heat a greenhouse 21 feet by 15, it is 

 necessary to have two four-inch pipes along both ends, and in 

 front, if a lean-to, or all round if a Epan.

In the above estimate, everything is good, substantial, and 

 calculated to last the owner's lifetime. Rut there are cheaper 

 wayB than this. Substitute a small Arnott-stove boiler for the 

 saddle, use pot-pipes, cement the joints, and you will have a 

 cheaper and a better apparatus than any kind of flue whatever, 

 for any kind of hot-water apparatus is better than flues however 

 well constructed. 



A small Arnott-stove boiler can be had for 30s., and a yard 

 each of four-inch iron pipe connected to flow and return, to 

 which the pot-pipes are joined, is requisite. The cost of the 

 whole for a house 21 feet by 15, is as folio wb : —

 The boiler can be inside at the option of the proprietor, and 

 a hotbed can be formed there to strike cuttings and raise flower- 

 seeds without the trouble of making a hotbed of dung ; but the 

 doors for the sake of cleanliness should be outside. In con- 

 necting the pipes to the boiler it is of importance to allow a 

 rise of 1 foot from the boiler. Some do this along the pipes, 

 gradually allowing them to rise from the boiler to the flow- 

 box; but I prefer the rise at the boiler through a bend, and 

 then carrying the flow as 

 nearly level as possible — that (^3) a 

 is, only allowing a rise of a 

 few inches so as to let the 

 extremity be the highest 

 point to let the air out of the 

 pipes at the feeding-ci6tern, 

 which is a somewhat novei 



contrivance — thus, being a ^v__ -~ retvrk 



bend with an additional 



branch, I do not see any necessity for a cistern, neither would I 

 have one unless the boiler is large, and, consequently, requires a 

 considerable quantity of water to provide for the waste arisinc 

 from circulation and evaporation. All that is usually needed 

 is a hole through which to pour water into the pipes (as at a 

 in the engraving), and that, of course, should be at the highest 

 point, thereby doing away with the necessity for air-pipes. The 

 return-pipe will, of course, be raised from the boiler gradually, 

 so that it will be of the desired height at which the pipes are to 

 run by the first bend ; and from that point allow a rise of 6 inches 

 in every 7 yards. The flow-pipe will rest on the return-pipe until 

 it comes to the point where the return falls to the boiler, when 

 the latter will be carried to meet the flow at its junction with 

 the boiler without dipping ; but should it dip it is not improb- 

 able that in filling the pipes with water this will run up the 

 return-pipe and meet the current coming down the flow at the 

 dip, and so prevent the water from circulating owing to the air 

 being confined there ; but even should the air rise (as it may 

 with a little pressure), to the feeding-pipe or cistern, the water 

 will not circulate so freely as when it rises from the boiler with- 

 out dipping, and not at all if air be confined at the dip or any- 

 where along the pipes bo as to cause an empty space in the pipe.

THE PELABGONIUM GARDEN. 



Foe the preparation of the annexed nlan I am indebted to my 

 tasteful friend, M. H. Seitz, of ChatBworth. There is apparent 

 in this garden a judiciouB blending of gravel and grass, pro- 



ductive of a light and airy elegance that garden artists of greater 

 celebrity would not do amiss to profit by. Unfortunately for 

 good teste, gardens of this kind in general exhibit such a crowd- 

 ing, clumsiness, and incongruity of disposition in the Beveral 

 figures, as to render the tout ensemble, in good perspective, the 

 very reverse of elegant, comprehensive, and dignified. Too 

 many figures in a plan, or the separate parts of the latter too 

 widely Bpread asunder, when the entirety should rather be ex- 

 pressive of nicety in design, can but result in deformity and 

 dissatisfaction when displayed in practice on the ground, how- 

 ever well suited the Bame arrangement might previously have 

 appeared on paper to the uninitiated in such matters. 



The vignette exhibits in perspective the accompanying ground 

 plan circumscribed with trelliage arches about 9 or 10 feet 

 nigh, formed of stout rod-iron, inserted into blocks of stone 



beneath the surface of the ground ; and a marble figure of 

 " Flora " is presumed, not inappropriately, to occupy the centre 

 of the parterre. The Pelargonium garden at Oakley, the Duke 

 of Bedford's, is thus circumscribed with iron arches ; and the 

 airy elegance thus imparted, when entwined and festooned with 

 hardy and summer greenhouse climbers in great variety, is not 

 the least attractive feature of the scene. A seldom UBed, but 

 most classic plant for this kind of decoration is the Grape Yine. 

 And when in early autumn the foliage of various hardy species 

 of Vitis assume a variety of tints, and ripe and unripe bunches 

 of tirapes in " bacchanal profusion reel to earth," or rather 

 depend from these arches, partly concealed by green, and red 

 and green, and purplish foliage, the effect is extremely pleasing, 

 reminding one of Byron's lines on Italy — 



" Who love to see the sunshine every day 

 And Vines (not nailed to walls) from tree to tree 

 Festooned, much like the back scene of a play." 



The only difference being that the sun, perhaps, does not shine 

 so brightly as it does in Italy, and that our Vines, instead of 

 being " festooned from tree to tree," are merely trained from 

 arch to arch. In addition to the Grape Vine, Clematis, Jasmine, 

 Roses, Virginian Creepers, Honeysuckles, and other hardy 

 climbers, are rendered decidedly more elegant and graceful in 

 summer time by having such half-hardy greenhouse creepers as 

 Maurandya, Lophospermum, Khodochiton, Loasa, Tropseolum, 

 Cobcea, &c, planted at their base annually, and induced to 

 loosely enwreath themselves and ramble over their more sturdy 

 compeers. 



The flower-baskets also constitute an interesting feature in 

 connection with the Pelargonium garden at Oakley ; and, Bince 

 this particular kind of ornament is not in very general use, the 

 following particulars relative to it may not be considered out of 

 place : — The basket portion is composed of robust, closely-inter- 

 woven wiekerwork, annually painted green, both for effect and 

 for the preservation of the comparatively frail material of which 

 it is composed. In form it is circular, and made to rest upon a 

 substantial wooden frame or support, constructed with a view 

 to strength as well as ornament. This ornamental stand is about 

 18 ineheB or 2 feet high, square in shape, with a circular top 

 corresponding to the diameter of the basket bottom, and like the 

 latter, is painted green to preserve the wood, as also to harmonise 

 in colour with the superstructure which it upholds. The flower- 

 basket itself is about 5 feet diameter at top, 2J feet across at 

 bottom, and about 3 feet in depth. The interior is necessarily 

 furnished with a portable lining of sheet-iron next the wicker- 

 work, perforated at bottom with numerous apertures for the 

 escape of moiBture descending through the soil, and Binee the 

 basket itself is bottomless, the circular false bottom of per- 

 forated Bheet-iron (though, of oourse, placed inside the basket), 

 is necessarily made to reBt chiefly upon the ornamental latticed 

 frame which supports it. It is, of course, a portable contrivance 

 in teto, being disposed in winter in some dry airy place for the
