flibjcct to Damps, it \hou\d be raisd 

 at leall three Feet above the Surflice : 

 And under the Floor, about two 

 Feet trom the Front, I would ad- 

 vile a Fine of about ten Inches in 

 width, and two Feet deep, to be 

 carry 'd the whole Length of the 

 Houle, which may be return'd 

 along the Back- part, and becarry'd 

 up in proper Funnels adjoining to 

 the Tooi-houfe, by which the 

 Smoak may pais off. The Fire- 

 place may be contriv'd at one End 

 of the Houfc i and the Door at 

 which the Fuel is put in, as aUb 

 the Adi-grate, may be contriv'd to 

 open into the Tool- houle, fo that it 

 may be quite hid from the Sight, 

 and be in the Dry ; and the Fu^l 

 tnay be laid in the fame Place, 

 whereby it will be always ready 

 for Ufe. 



I fuppofe many People will be 

 furpriz'd to fee me direft the 

 making of Flues under a Green- 

 houfe, which have been difus'd i'o 

 long, and by moll People thought 

 of ill Confequence j as indeed they 

 have often prov'd, when under the 

 Direftion of unskilful Manager?, 

 who have thought it necellary, 

 whenever the Weather v/as cold, 

 to make Fires therein. But how- 

 ever injurious Fiues have been under 

 iuch Mifmanagement, yet when 

 skilfully manag'd, they are of very 

 great Service: for tho' perhaps it 

 may happen that there will be no 

 NccelTity to make any Fires in 'em 

 for two or three Years together, as 

 when the Winters prove mild there 

 will not, yet in very hard Winters 

 they will be extremely ufeful to 

 keep out the Froft i which cannot 

 be effcded any other way, but 

 with great Trouble and Difficulty. 



Wirhin-fide of the Windows, in 

 Front of the Green- houfc, you 

 iliculd have good ftrong Shutters, 



G k 



which ihould be made with Hinges^ 

 to fold back, fo that they may tall 

 back quite clofe to the Piers, that 

 the Rays of the Sun may not be 

 obftruded thereby : Thefe Shut- 

 ters need not to be above an Inch 

 and a Half thick, or little more, 

 which, if made to join clofe, will 

 be ItifHcient to keep out our com- 

 mon Froft: J and when the Weather 

 is ib cold as to endanger the Freez- 

 ing in the Houle, it is but making 

 a Fire in your Flue, which will 

 effedtually prevent it: And without 

 this Conveniency it will be very 

 troublefome, as I have often {ccn, 

 where Perfons have been oblig'd to 

 nail Mats before their Windows, or 

 to ft:ufF the hollow Space between 

 the Shutters and the Glafs with 

 Straw; which when done, is coin- 

 moniy fuffer'd to remain till the 

 Froft goes away ; v/hich, if it 

 fliould continue very long, the keep- 

 ing the Green-houfe fo clofely ihut 

 up, will prove very injurious to the 

 Plants : And as it frequently happens 

 that we have an Hour or two of the 

 Sun-fliine in the Middle of the Day, 

 in continued Frofl:s, which arc 

 of great Service to Plants, when 

 they can enjoy the Rays thereof 

 through the G.alTes, fo when there 

 is nothing more to do than to operi 

 the Shutters, which may be per- 

 form'd in a very fhort Time, and 

 as fbon fhut again when the Sun is 

 clouded, the Plants may have the 

 Benefit thereof whenever it appears j 

 v/hereas where there is fo much 

 Trouble to uncover, and as much to 

 cover again, it would take up the 

 whole Time in uncovering and 

 thutting them up, and thereby the 

 Advantage of the Sun's Influence 

 would be loft. Belides, where there 

 is fo much Trouble requir'd to keep 

 out the Froft, it will be a great 

 Chance if it be not negled^d by
