lire), rmift be rais'd two Feet above 

 the Surface of the Ground whereon 

 theHoufe is placed ; which, in dry- 

 Ground, will be fufficient : but if 

 the Situation be moilt and fpringy, 

 and thereby fubject to Damps, it 

 Ihould be rais'd at lead three Feet 

 above the Surface: and if theVVhoie 

 is arched with low Brick Arches, un- 

 der the Floor, it will be of great Ser- 

 vice in preventing the Damps riling 

 in Winter, which are often very hurt- 

 ful to the Plants, efpecially in great 

 Thaws, when the Air is often too 

 cold to be admitted into the Houfe, 

 to take off the Damps. Under the 

 Floor, about two Feet from the 

 Front, I woulo 1 ad vile a Flue of 

 about one Foot in Width, and two 

 Feet deep, to be carried the whole 

 Length of the Houfe, which may be 

 returned along the Back-parr, and 

 be carried up in proper Funnels ad- 

 joining to the Tool houfe, by which 

 the Smoke may pals off. The Fire- 

 place n.ay be contrived at one End 

 of the Houfe ; and the Door at 

 which the Fuel is ]put in, as alfo the 

 Afti-grate, may be contrived to open 

 into the Tcol -houfe ; lb that it may- 

 be quite hid from the Sight, and be 

 in the Dry ; and the Fuel may be 

 laid in the fame Place, whereby it 

 will always be ready for Ufe. 



I fuppofe many People will be 

 furprifed to fee ine direct the making 

 of Flues under a Green-houfe, which 

 have been difufed fp long, and by 

 jnofl People thought of ill Confe- 

 rence ; as indeed they have often 

 proved, when under the Direction 

 f)f unfkiiful Managers ; who have 

 (nought it neceiiary, whenever the 

 Weather was cold, to make Fires 

 therein. But however injurious Flues 

 have been under fuch Management, 

 yzt when ikilfully managed, they 

 ure of very great Service : for tho' 

 perhaps it may happen, that there 



will be noNeceffity to make anyFire* 

 in them for two or three Years to- 

 gether, as, when the Winters prove 

 nnld, there will not, yet in very 

 hard Winters they will be extremely 

 ufeful to keep out the Froit ; which 

 cannot be erfe&ed any other Way, 

 but with great Trouble and Diffi- 

 culty. 



Withinfide of the Windows, in 

 Front of the Grecn-honfe, you 

 ihould have good ftrong Shutters, 

 which mould be made with Hinges, 

 to fold back, that they may fall 

 back quite clofe to the Piers, that 

 the Rays of the Sun may not be ob- 

 ftructed thereby. Thefe Shutters 

 need not to be above an Inch and 

 an half thick, or little more ; which, 

 if made to join clofe, will be fuffi- 

 cient to keep out our common Froft : 

 and when the Weather is fo cojd as 

 to endanger the freezing in thcHoufe, 

 it is but making a Fire in your 

 Flue, which will effectually prevent 

 it : and without this Convcniency it 

 will be very troublefome, as I have 

 often feen, where Persons have been 

 obliged to nail Mats before their 

 Windows, or to fluff the hollow 

 Space between the Shutters and the 

 Glafs with Straw j which, when 

 done, is commonly fuffered to re- 

 main till the Froft goes away ; which 

 i) it mould continue very long, the 

 keeping the Green-houfe clofely fhut 

 up, will prove very injurious to the 

 Plants : and as it frequently happens, 

 that we have an Hour or two of the 

 Sun-mine in the Middle of the Day, 

 in continued Frofts, which is of great 

 Service to Flants, when they can en- 

 joy the Rays thereof through the 

 Glaffes ; fo, when there is nothing 

 more to do than to open the Shut- 

 ters, which may be performed in 

 very fhort time, and as foon ihut 

 again when the Sun is clouded, the 

 Plants may have^ the Benefit thereof
