the fire-place or flues be carried too near any of 

 the wood work. 



After this, proceed to set out the cavity for 

 the bark-pit, first allowing a space next the 

 flues for an alley or walk, cighletn inches or 

 two feet wide all round, and iIkii in the middle 

 space tonn the pit for thi.- bark-bid, six or seven 

 feet wide, the len£;th in proportion to that of tiie 

 Hmise, and a yar3 or more deep; inclosing it by 

 a burroiuidins^ wall. It may cither be sunk at 

 boitom a little in the ground, raising the rest 

 above, by means of the parapet wall; or, if 

 there is danger of wet below, it should be rais- 

 ed most)' above the general surface. The sur- 

 rounding wail should be nine inches, but a 

 brick-wide wall is ofien made to do, especially 

 that part v.hich forms the parapet above ground. 

 It should be coped all round with a timber plate 

 or kirb, framed ai.d mortised together, which 

 efleciually secures the bnck-work. 



The bottom of the pit should be levelled and 

 well rammed, and it paved with any coarse 

 material, <t is an advantage in preserving the 

 bark. And the path or alley roimd the pit must 

 be nearly paved with brick or stone. 



The class-work for inclosing the whole should 

 consist of a close-continued range of gia^s 

 sashes all along the front, both ends, and roof, 

 quite up to the back wall ; each sash being a 

 vard, or three feet six inches wide ; and for the 

 support of which, framings of timber must be 

 erected on the brick-walling, conformable to the 

 width and length of the sashes. 



For the reception of the ptr|:endicular glasses 

 in the front and ends, a substaiitinl limber plate 

 must be placed along the top of the front and 

 end walls, upon which shtjuld be erected up- 

 rights, at proper distances, frnmed to a plate or 

 crown-piece above, of surfieient height to raise 

 the whole front head high, both ends corre- 

 sponding with the front and back; a pla'.e of 

 timber beins: also framed to the back wall above, 

 to receive the sloping bars from the frame-work 

 in front ; proper grooves being formed in the 

 front plates below and above, to receive the 

 ends of the perpendicular sashcs, sliding close 

 against the outside of the uprights all the way 

 aloniT the front, or tiiey may be conirived ior 

 onlv every other sash, to slide one on the side 

 of the other. 



And from the top of the upright framing in 

 front should be carrud substantial cross-bars or 

 bearer?, sloping to the top of the back wall, 

 where they are framed at both ends to tiie wood- 

 work or plates, at rcguhr distances, to receive 

 and support tlie sloping glass sashes of the roof, 

 when placed close together upon the cross bars 

 •r rafters, and generally rangmg in two or more 



tiers, sliding one over the other, of sufficient 

 length together to reach quite fioni the top of 

 the uprieht framing in from, to the top of the 

 back-Wall. The cross bars should be grooved 

 lengthwavs, above, to carry off' wet fallinsi be- 

 tween the frames of the sloping lights ; making 

 the upper end of the top tier ot glass.cs shut 

 close up to the plate in the wall behind, running 

 under a proper coping -of wood or lead, fixed 

 along above close to the wall, and lapped down 

 of due width to cover, and shoot otf the wet 

 sufficiently l.om the upper termination of the 

 top sashes. Some widi- Houses have, exclusive 

 of the main slope sliding glass sashes, a snorter 

 upper tier of glass fixed ; the upper ends being 

 secured under a coping as above, and the lower 

 ends lapping over the top ends of the upper 

 sliding tier, and tiiis over that below in the 

 same manner, to shoot the wet clear over each 

 upper end or termination ; likewise alonsr the 

 under outer edge of the top plate, or crown- 

 piece in front, may be a small channel to re- 

 ceive the water from the sloping glass sashes, 

 and convey it to one or both ends without run- 

 ning down upon the upright sashes, being care- 

 ful that the top part behind be well framed and 

 sctiired, water-tighi, and the top of the back 

 wall finished a little higher than ihcglas»es, u ith 

 a neat copma the w hole lenath. 



The bars of wood which support the glasses 

 should be neatly formed, and maJe neither very 

 broad or tiiick to intercept the rays of the sun. 

 Those, however, at lop, should be strong 

 enough to support the glasses without bending 

 under them. In wide floi.ses uprights are ar- 

 ranged within at proper distances, to support 

 the eross rafters mure perfectly. 



in respeci to the glass work in the sloping 

 sashes, the panes of glass should be laid in 

 putty, with the enus lapping over each other 

 about half an inch ; the vacancies of which are 

 in some closed up at b.ittom with putty, others 

 leave each lapping uf the panes open, in order 

 for the air to enter moderately, and that the 

 rancid vapours arising from the fermentation of 

 the bark-bed, Jvc. w ithin, may thereby be kept 

 in constant motion without condensing much ; 

 and also that such ;.s condense against the 

 glasses, may discharge itself at those places 

 without dropping upcii the plants. The upri^'lit 

 sashes in front mav either be glazed as abtve, 

 or the panes laid m lead work ; beinir very 

 careful to have the glazing well performed, and 

 pr>>of airaitist wet. 



fhe doors should hav* the upper part* sailed 

 and glazed to correspond with ihe other glass- 

 work. 



On the inside the walls should be plastered.
