a; the Pine-?.pplc requires to be cor.dnntly kept very 



in order to ripen the fruit well, fo it will be 



lat the depth I have allowed 



will 



warm, 



found upon trial, th 

 anpA er that purpofe better than a greater. 

 But if the Bed be intended for taller plants, then the 

 frame muft be made in depth proportionable thereto ; 

 but if it be for fowing of feeds, the frame need not be 

 above fourteen or fixteen inches high at the back, and 

 feven inches deep in the front, by which means the 

 heat will be much greater ; and this is commonly the 

 proportion allowed to the frames ufually made ufeof 

 jn the kitchen-gardens. As to their length, that is ge- 

 nerally according to the fancy of the owner-, but they 

 commonly contain three lights each, which is in the 

 whole about eleven feet in length, though fometimes 

 they are made to contain four lights j but this is too 

 great a length for the boxes, for the frames thus made 

 ' are not fo handy to remove, as when they are fhorter, 

 and are more fubjefl to decay at their corners. Some 



* indeed have them to contain but two lights, w^hich is 

 ' very handy for raifing Cucumber and Melon plants 



while young; but this is too fhort for^a Bark-bed, as 

 not allowing room for a proper quantity of bark to 

 continue a warmth for any confiderable time, as was 



■ before- mentioned ; but for the other purpofes, one or 

 ' two fuch frames are very convenient for common 



Dung-beds, 



As to thofe frames which are made very deep, it is 



' much the better way to have them made to take afun- 



der at the four corners, fo that they may be removed 



with eafc ^ otherwife it will beVery difficult to take the 



■ frame off, when there is qccafion to put in new bark, 

 ' or take out the old. The manner of makino^ thefe 



frames is generally known, or may be much better 



conceived by feeing them than can be exprefled in 



. writing, 'therefore I fhall forbear faying any thing 



more on this head.

HUMIDITY is the quality commonly called mbi- 

 - fture, or the power of wetting others, which quality 

 lom.e hquors arid fluids are endowed with ■, and it dif"- 

 fers very m.uch from fluidity, in that it depends alto- 

 gether on the congruity of the component panicles 

 of any liquor to the pores orfurfaces of fiich particu- 

 lar bodies, as it is capable of adiiering to. 

 Thus, quickfilver is not a moift liquor, in refpeft to 

 our hands or clothes, and many other things itVnll 

 hot*fl:ick to ; but it may be called a moifl liquor, in 

 tefpeft to gold, lead, or tin, to the furfaces of whick 

 it will preiently adhere. ■ 



Nay, water itfelf, thaf \^ets alrhoft every thing, 

 and is the great fl:andard of Humidity, or nioifl:urci 

 is not capable of whetting every thing -, for it fl:ands, 

 and runs eafily off^iri globular drops, on the leaves 

 of Cabbages, and many other plants -, and will not 

 wet the feathers of ducks, fwaris, and othdr water 

 fowl. 



And it is very plain, that it is ohly the textiire that 

 may caufe the fluid to be hiimid ; becaufe neither 

 quickfilver alone, nor bifmuth, will fl:ickup6ri glafs; 

 yet being mixed together, they will form a mafs that 

 will fl:ick on it j' as it is very well known in the fo- 

 liating of looking-glaflTes, ih which fuch a compo- 

 ' fition is ufed.
