that the ftcam drops upon the plants, which is of mofl 

 pernicious confcquence. 5^0, The flied to inclofe the 

 fronts of the ovens fliould have the doors in the ends, 



and 



Ught in the houfe. The flues fhould be firfl covered 

 with brosd tiics, and then a bed of land laid over them, 

 about two inches thick, upon which the plain tiles 

 fhould be laid, to correfpondwith the reft of the floor. 

 This thicknefs of cover will be lull enough to prevent 

 the too fudden rife of the heat from the flues. 



But if the furnace is placed under the floor, the thick- 

 nefs of the fand between the brick arch that covers it, 

 and the floor, fliould not be lefs than four or fix inches; 

 io that the bottom of the furnace fhould be funk the 

 lower ; and if from the fire-place to the end ot the 

 houfe, the flues are laid a little rifing, it will caule them 

 to draw the better; but this rife muft be allowed in the 

 placing them lower under the floor next the fire, becaufe 

 the floor mult be laid perfeflly level, oihcrwife jt will 

 appear unfightly. 



In this ftove there fliould be a ftand or fcaffold erect- 

 ed tor placing flielves above each other, in the manner 

 of Fig. n. in the plate, that the plants may be difpofed 

 above each other, fo as to make a handfomc appearance 

 in the houfe ; but thefe {helves fliould be made move- 

 able, fo as to be raifed or funk, according to the various 

 heights of the plants ; otl'Crwife it will be very trouble- 

 fome to raife or fink every particular plant, according 

 to their heights, or every year as they advance in their 

 growth. 



In placing the feet of this ftand, you muft be careful 

 not to fet them too near tlie fire, nor directly upon the 

 top of the flue, cfpecially that end next the fire, left, 

 by the conftant heat of tlie tiles, the wood fliould take 

 fire, which cannot be loo much guarded againft ; fincc 

 Aich an accident would probably deftroy all the plants, 

 if the houfe efcaped being burnt. This ftand or fcaf- 

 fold ftioLild be placed in the middle of the hou'e, leav- 

 ing a pafl'agc about two feet and a half in the front,
