whenever it appears ; whereas, where 

 there is fo much Trouble to uncover, 

 and as mucn to cover again, it would 

 take up trie whole Time in uncover- 

 ing and (hutting them up, and there- 

 by the Advantage of the Sun's In- 

 fluence would be loft. Befides, where 

 there is fo much Trouble required to 

 keep out the Froft, it will be a great 

 Chance if it be not neglected by the 

 Gardener : for if he be not as fond 

 of prefer v lug his Plants, and as much 

 in love with them, as his Mailer, 

 this Labour will be thought too great 

 by him j and if he takes the Pains 

 to cover theGlailes up with Mats. 

 crV. he will not care to take them 

 away again until the Weather alters ; 

 fo that the Planes will be lhutup clofe 

 during the whoie Continuance of the 

 Froft. 



There are fome People who com- 

 monly make ufe of Pots rilled with 

 Charcoal to fet in their Green-houfe 

 in very fevere Froils ; but this is 

 very dangerous to the Perfons who 

 attend thefe Fires; and I have often 

 known they have been almoft fuffo- 

 cated therewith ; and at the fame 

 time they are very injurious to the 

 Plants: nor is the Trouble of attend- 

 ing upon thefe fmall ; and the many 

 Hazards to which the Ufe of thefe 

 Fires is liable, have juftlv brought 

 them into Difufe with all ikilful Per- 

 fons ; and as the Contrivance of 

 Flues, and of the Fires, are but fmall 

 Charges, they are much to be pre- 

 ferred to any other Method for 

 warming the Air of the Houfe. 



The Back part of the Houfe 

 mould be either laid over with Stucco, 

 or plaftered with Morter, and white- 

 warned ; for other wife the Air in fe- 

 vere Froft wdl penetrate through the 

 Walls, efpecially when the Froft is 

 attended with a ftrongWind ; which 

 is often the Cafe in the moll: fevere 

 Winters. There are fome Perfons 



who are at the Expence of wainfeot- 

 ing their Green houies; but when 

 this is done, it is proper to plafter 

 the Walls with Lime and Hair behind 

 the Wainfcot, to keep out the Cold ; 

 and when they are lined with Wain- 

 fcot, they mould be painted white, 

 as mould the Cieling, and every Part 

 withinhde of the Houfe : for this re- 

 flects the Rays of Light in a much 

 greater Quantity than any other Co- 

 lour, and is of fignal Service to 

 Plants, efpecially in the Winter, 

 when the Houfe is pretty much 

 clofed, and but a fmall Share of 

 Light is admitted through the Win- 

 dows : for at fuch times I have ob- 

 served, that in fome Green ho ufes 

 which have been painted black, or 

 of a dark Colour, the Plants have 

 caft moll of their Leaves. 



Where Green-houfes: are built in 

 fuch Places as will not admit of 

 Rooms over them 5 or the Perfon is 

 unwilling to be at the Expence of 

 fuch Euildings, there mull: be Care 

 taken to keep out the Froft from en- 

 tering through the Roof. To pre- 

 vent which, it will be very proper 

 to have aThicknefs of Reeds, Heath, 

 or Furz, laid between the Cieling 

 and the Tiles : in the doing of which 

 there muft be Care taken in framing 

 the Joifts, fo as to fupport thefe, that 

 their Weight may not lie upon the 

 Cieling-joifts, and endanger it : fof 

 thefe mould be laid a Foot thick 

 at leaft, and as fmooth as pofiib!e, 

 and fattened down well with Laths, 

 to prevent their rifing; and then 

 covered over with a Coat of Lime 

 and Hair, which will keep out the 

 Air, and alfo prevent Mice, and 

 other Vermin, from harbouring in 

 them ; which, if left uncovered, they 

 would certainly do. For want of this 

 Precaution, there are many Green- 

 houfes builr, which will not keep 

 out the Froft in hard Winters ; and
