tender fucculent Plants, which re- 

 quire to be kept dry in Winter. 



As in this Stove are plac'd the 

 Plants of the hotteft Parts of theEaft 

 and IVeJi-Indies, fo the Heat mould 

 be kept up equal to that mark'd 

 Anana upon the Botanical Thermo- 

 meters, and mould never be fuffered 

 to be above eight or ten Degrees 

 cooler at moft ; nor fliouid the Spi- 

 rit be raifed above tenDegrees higher 

 in the Thermometer during the 

 Winter - feafon ; both which Ex- 

 tremes will be equally injurious to 

 the Plants. 



But in order to judge moreexaclly 

 of the Temper of the Air in the 

 Stove, the Thermometer Ihould be 

 hung up at a good Diftance from 

 tht Fire ; nor mould the Tube be 

 expo to the Sun ; but on the con- 

 trary, the Back hung thereto \ be- 

 came whenever the Sun mines upon 

 the Ball of the Thermometer but 

 one fingle Hour, it will raife the Li- 

 qjorin >heTube confide] ably, hen, 

 perhaps, the Air of the Houie is not 

 near ib warm ; which deceives thofe 

 who are not aware of this. 



In the Management of the Plants 

 placed in the Bark-bed, there mult 

 be a particular Regard had to 

 the Temper of the Bark, and the Air 

 of the Houfe, that neither be too vi- 

 olent ; as alfo to water them fre- 

 quently ; becaufe when they are in 

 a continual Warmth, which will 

 cauie them to perfpire freely, if they 

 have not a conitant Supply to amwer 

 their Diicharge, their Leaves will 

 decay, and foon fall off. As to the 

 f irtnerDirections concerning theCul- 

 ture of the particular Plants, the 

 Reader is defired to turn to their fe- 

 yeralArticles,where they are c;:iincU 

 ly treated of. 



The other Sort of Stove, which is 

 commonly caiTd the Dry Stove, as 



s T 



was before faid, may be either built 

 with upright and Hoping Glades at 

 the Top, in the fame manner, and 

 after the fame Model, as the Bark 

 Stove ; or elfe the Front - glalTes, 

 which mould run from the Floor to 

 the Cieling, maybe laid floping,to an 

 Angle of 45 Degrees, the better to 

 admit the Rays of the Sun in Spring 

 and Autumn : the latter Method 

 has been chiefly follow'd by molt 

 Perfons who have built thefe Sort of 

 Stoves : but were I to have the 

 Contrivance of a Stove of thisKind, 

 I would have it built after the Mo- 

 del of the Bark Stove, with upright 

 Glaffes in Front, and Hoping Glafies 

 over them, becaufe this will more 

 eafily admit the Sun at all the differ- 

 ent Seafons ; for in Summer, when 

 the Sun is high, the top GlalTes will 

 admit the Rays to Ihine almoft all 

 over the Houfe ; and in Winter, 

 when the Sun is low, the front GlalT- 

 es will admit its Rays ; whereas 

 when the GlalTes are laid to any 

 Deciivity in one Direction, theRays 

 of the Sun will not fall directly 

 thereon above a Fortnight in Au- 

 tumn, and about the lame time in 

 Spring ; and during the other Parts 

 of the Year they will f tl obliquely 

 thereon ; and in Summer, when the 

 Sun is high, the Rays will not reach 

 above five or fix Feetfron. tncGlalT- 

 es : befides, the Plants which are 

 p'.ac'd toward the Back - part of the 

 Houfe will not thrive in the Sum- 

 mer-feafon for want of Air ; where- 

 as when there are Hoping GlalTes at 

 the Top, which run within four 

 Feet of tne Back of theHoufe; thefe, 

 by being drawn down in hot Wea- 

 ther, will let in perpendicular Air to 

 all the Plants ; and of how much 

 Service this is to all Sorts of Plants, 

 every one who has had Opportunity
