fbns for this Work; but in the 

 doing of it, you (hould be careful 

 to preferve the Earth to their 

 Roots, and only to pare off the 

 Outlide of the Ball, cutting away 

 ail mouldy or decay'd Fibres j then 

 put them into Pots, one Size big- 

 ger than thole which they came 

 out of, filling up the Pots with 

 the before- mention'd Earth, obfer- 

 ving to water and fliade them, as 

 the Heat of the Weather lliall re- 

 quire: And if at thcfe Times you 

 mix a little new Bark in the Bed, 

 to add a trelh Heat thereto, before 

 the Pots are plung'd therein, it 

 will greatly facilitate their rooting 

 again, but you muft be careful not 

 to make the Bed too hot : You 

 iliould alfo, in Summer-time, re- 

 frelh all the Branches and Leaves 

 of the Trees, by watering them 

 gently with a fine headed Water- 

 ing-pot all over their Heads j and 

 if in a very warm, gentle Shower 

 of Rain, you draw oit the Top- 

 -GlalTes of the Stove, and let them 

 receive the Benefit thereof, it will 

 be of great Service to them : but 

 you muft be careful not to expole 

 them to hard Rains, or ftrong 

 Winds, which v/ould prove very 

 hurtful to them. 



Thefe Dircd: ions, if carefully at- 

 tended to, will be found fufficicnt 

 to inftiuft any Pcrfon in the Cul- 

 ture of this beautiful Plant j and 

 although there may, perhaps, fome- 

 thing occur to them which is not 

 here related, yet I believe it will 

 rarely happen, but that the Appea- 

 rances, be they from what Caufe 

 ibevcr, may be found owing to 

 fome Ncgled: or contrary Pradice 

 to this here mentioned: But be- 

 fore I leave this Head, I cannot 

 help mentioning another Method 

 in which I have propagated this 

 Plant i which is, by hying down

fbme of their tender Shoots into 

 Pots of Earth in the Spring of the 

 Year, flitting them at a Joint (as 

 is praftifed in laying Carnations) 

 obferving to rcfrelh them frequent- 

 ly with Water, and in about three 

 Months Time they will be rooted 

 enough to tranfplant, when they 

 Ihould be gently cut from the old 

 Plant, and planted into feparate 

 Pots, managing them as was dire- 

 died for the feedling Plants. 



There are Ibme who have aC- 

 ferted, that this Plant will grow 

 from Cuttings j but of all the dif- 

 ferent Trials which 1. have m.ide, 

 I could never obtain one Plant 

 that way, tho' many Times the 

 Cuttings have remained frefh for 

 fever al Montlis, and fometimes 

 have made Imail Shoots, yet upon 

 taking them up, they have not 

 had the lealt Appearance of any 

 Roots.

JET DEAU, is a French Word, 

 v/hich fignifies a Fountain that 

 cafis up Water to any ccnfiderable 

 Height in the Air. 



Mr. Mariotte, in his Treatlfe of 

 Hydrojlaticks, fays, That a Jet than 

 will never rife lb high as its Re- 

 fervatory j but always falls fhort of 

 it by a Space which is in a iubdu- 

 plicate Ratio of that Height, and 

 this he proves by feveral Experi- 

 ments. That tho' fets ought to 

 rile to the Height of the Referva- 

 tories, yet the Friction of the 

 Sides of the Adjutages, and the Rc- 

 fiftance of the Air, are the Caufcs 

 that in Jets that have very high 

 Refer vatories, the Height of the 

 Jets does not come up to that of 

 the Refervatory by a great deal.
