thefc SlOVC?^ the plants are placed on flielvcs of boards 

 laid on a fcaffold, rifing above each other like the 

 Icats in a theatre, for the greater advantage of their 

 ftandin^ in fight, and enjoying an equal fliare of 

 licrht and air. In thefe Stoves are comiPiOnly placed 

 tlftr tender forts of Aloes, Cereufes, ^Euphorbiums, 

 Tithymals, and other fucculent plants, which are im- 

 patient of moiLlure in winter, and therefore require 

 for the moft part to be kept in a feparate Stove, and 

 not placed among trees or herbaceous plants, which 

 perfpire freely, and thereby oTteh'caufc a damp air in 

 the houfe, which is innbibed by the fucculent plants 

 to tlicir no fmall prejudice. Thefe Stoves may be re- 

 o-ulated by a thermometer fo as not to over-heat them, 

 nor let the plants fufFer by cold ; in order to which, 

 all ftich plants as require nearly the fame degree of 

 hear^ fl^iould be placed by themfelves in a^feparate 

 houfe, for if in the fame Stove there are plants placed 

 of many different countries, which -require as many 

 different heats, by making the hbufe warm' enough 

 for fome ^plants," others, by having too much heat, 

 are dra'.vn and fpoiled., ' V 



The other fort of Stoves are commonly called bark 

 Stoves, to diftinguilh^ them from the dry Stoves 

 already mentioned. Thefe have a large pit, nearly the 

 length of the houfe, three feet deep, and fix or feven 

 feef wide, according to the breadth of the houfe, 

 which pit is filled with frelli tanners bark to make a^ 

 hot-bed, and in this bed the pots of the moft tender 

 exotic trees .and herbaceous plants are plunged.^ 

 The heat of this bed being moderate, the roots ' of 

 the plants are always kept in aftiori, and the moifture 

 detained bv the barkf keeps the fibres'^ 'of their rqots 

 in a duftile ftate, which in the dry Stove, .where they 

 are placed on Ihelves, are fubjedl to dry too faft, to 

 the great injury of the' plants. In thefe Stoves, if 

 they are rightly contrived, may bepreferved the moft 

 tericter'' exotic trees and plants, which, before the 

 life of the bark' was introduced, were thought impofn- 

 ble to be kept in England i but, as there is fome fl^ill 

 reqiiired in the ftruclure of both thefe Stoves, I ftiall 

 not only defcribe them' as intelligibly as poffible, but 

 alfo annex plans of both Stoves hereto, by which it 

 is hoped every curious perfon will be capable of di- 

 refting his workmen in their ftrufture. : 



The dimenfion'of'tKefe Stoves fhould be propor- 

 tioned tojhe number of plants intended^to be pre- 

 ferved, or "the 'particular fancy of the' "owner, but 

 tl-icir length ftibi-ild "nofexceed forty feet forgone fire- 

 place ; but where there are two fires it will be proper 

 to make a partition of glafs in ttie middle, and to 

 have two tan-pits, that there may be two different 

 def2;rces of heat for plants from different countries 

 (fol-the reafons before given in the 'acco'intoT dry 



■ Stoves ;) and were I to ereft'a range of Stoves, they 



■ fliould be all built in one, and only divided with glafs 



' partitions, at leaft the half way toward 'the front, 



which will be of great advantage to the plants, be- 



caufe they may have the air in each divifion Ihifted 



by aiding the glaffes'.of the partitions, of by opening 



■ the ryjafs'door which fliould be made between each di- 

 ' vifioli, for the m^ore eafy paffage from one to the other. 

 - Thefe Stoves fhould be raifed above the level of 



the crroundj in proportion to the drynefs of the place, 



for ?f they are built on a moift fituation, the whole 



- fhould be placed upon the top of the ground,^ fb that 



^ the brick- work in front muft be raifed thr^e feet 



above the furface, which is the depth of the bark-bed, 



" ' ' ' *" ' ^ of lying 



in front 





o 



or feven feet long, and placed upright; their ditrien- 

 fion fhould be nine inches by fix, of yellow Fir ; but 

 from the top of thefe (liould be floping glaffcs, which 

 fliould reach within three feet of the back of the 

 Hove, where there fliould be a ftrong crown-piece 

 of timber placed, in which there fliould be a groove 

 made for the glaffcs lo Aide into-, the dimennon of 

 the floping timbers fliould be ten inches by nine of 



• yellow Fir, and the crown-plate one foot by nine or 

 ten inches of the farne timber. The wall in the Lack 

 part of the Stove fliould be at leaft thirteen inches 

 thick, but eighteen or tw^enty-two inches, which is 

 two bricks and a half, will be better, for the greater 

 'thicknefs there is in the back wall, the more heat 

 will be thrown to the front, whereby the air of the 

 Stove will be better warmed, and the building will be 



■ fo much ftronger ; for to this back wall the flues, 



- through' which the fmoke is to pafs, muft be joined. 

 This back wall fhould be carried up about fixteen.or 

 twenty feet high, or nlore for tall Stoves, that they 



'' may be of a proper height to fupport the timbers of 



- the back root^ \vhich cOversthe fhed behind the Siove. 

 \ Tne roof is faftened into the crown-piece before-men- 

 '[ tibned, which in tall Stoves fhould be' about thirty 

 '.- feet above theTurfacebf the tah-bcd, which v^ill give 

 -• a fufficient declivity to the floping glaffes to carry off 

 r the wet,'and be of a reafonable height for containing 

 :'• many tall plants. The back roof may Be flated, co- 

 V vered with lead, or tiled, according to the fancy of 

 \ the owner ; but the manner of the outfide building 

 -is better expreffcd by the annexed plan, than is poffi- 

 ble to be dcfcribed in words.

In the front of the houfe, before the tan-bed, there 

 fliould be a walk, about two feet wide, for the conve- 

 ;* niency of walldng; next to which the bark-pit muft 

 ' be placed, v/iiich ftioulcf be' in^ width' proportionable 



■ to tliVl)feadth'6f the houfe.' If the houfe is fourteen . 



- feet wide, whicli;is\^ a due proportion, the pit may 

 be eight feet wide, an5 behind the pit fKduld be a 

 walk two feet wide, to pafs, in' order to water the 

 plants, &c. then there ^vill be two feet left next the 

 back wall toereft the flues, which muft be all raifed 

 above the level of the bark-bed. Thefe flues ought 

 to be one foot wide in the clear, that they may not be 

 too foon flopped with the foot, as alfo for the more 

 conveniently cleaning them ; the lower flue, into 

 ■which the fmpkc flrft enters from the fire, fliould be 



: two feet deep In the clear ;' this fhould be' covered 

 '■ with broad tiles, which fhould be" a fbot and a. half ; 



- fquare, *^(ir o;ie- foot;^"by a foot and a half long,'^ that^ 

 '-they may be wide enough to extend over the 

 ^ wall in fronti'oF the flues, ^hd to take fufHcient hold 

 ^■^"of the'back waU 1 over this the fecond flue muft 

 *f be returned back again, v/hich may be tv/enty inches 

 "^'^deep^ and covered oh the top as^lD^fprei "and fo in 

 ■ 'like manner the flues may be returned oyer each 

 \ other fix or eight times, that the lieat* may 'be fpent

whereby none of the barkwillbe in danger i 

 in v/ater ; but if the foil be dry^ the brick- work 

 need not be more than one foot above ground, and 

 tlie pit'may be funk two feet below the furface. Upon 

 the top'of this brick-work in front muft be laid the 

 plate of timber, into which the wood-work of theframe 

 IS to be mortifed ; this Oiould be of found Oak felled 

 in winter; without fap, the dimenfion one foot wide, 

 and fix inches deep, and the upright timbers in front 

 muft be placed four feet afunder, or fomewhat more, 

 which is the proportion of the width of the glafs doors 

 or falhes ; thefe fliould be about fix feet and a half,

two, they fhould be placed at eaCh'end of the flied,

fires and the' back of the flues may not iuffei^ from 



"•the outer air-, for it will be impoffible to make the 



fires burn equally, where the wind has full Tngrefs to
