clination, to be placed by tlicir friends or lovers ; or to be re- 

 moved to a dirtance from their enemies ? 



i"^. Many plants grow well under the (hade of others ; but 

 none grow fo well as if unihaded, and in their nativity. 



14. Baneful; frequently dliloliition, if ft ruck with the material 

 fire or lightning. But, on the other hand, the growtli of many 

 plants is much promoted by the fultry moill heat, frequently at- 

 tendant on, or following athunder-ftorm. The electrical fluid is al- 

 fq known to be aiding to the growth of plants, by real experiment i 

 that is, by the circumambient air, or what may be called the im- 

 mediate atmofphere of the plant, being charged in a moderate de- 

 gree by the wheel, for feveral days together, vegetation has been 

 obferved to increafe in a very confiderable degree. 



15. If they are fituated at a confiderable diitance from the fea, 

 and the fea-air is mixed with frefli air before it comes into contaft 

 with the lungs of the plants, or the foil wherein they grow, it is 

 attended with little bad, perhaps good, effect ; but if they are li- 

 tuated on the brink of the ocean, the effefts are fuch, that they 

 are Hunted, hidebound, and all their juices are contaminated by 

 its baneful influence and aftringency, more efpecially while the 

 \vind blows from thence« 



III. Concerning Water. 



Anf. to Quef. i. Nourifhing the root, incrcaling the quantity of 

 f'ap, and refrelbing the foliage Waier is alfo probably the chief 

 vehicle by which the effence of dungs, and other manures, is con- 

 veyed into their fyftem. 



2. Soft, that is, river, rain, or waters that have been expofed 

 to the rays of the fun a confiderable time before application, are 

 favourable ; and hard, or waters that are impregnated with 

 metallic fubftances, are injuriqus to vegetation. 



3. Very bad for either, if perfifled in \ and more perceptibly 

 fo, at firlt, on young than old plants. 



5. Mornings and evenings, before and after the fun's heat is 

 violent, becaufe, otherwife, it would be rendered of lefs beneficial 

 eflfed, owing to fudden exhalation. 



6. As long as a tree or plant (/. e. the flem, branches, or 

 haulm) can be faid to be in life, its fap undoubtedly flows in a 

 greater or lefs degree. For inftance, cut any part of a vine, birch, 

 fycamore, oak, &:c. in the dead of winter, the juices will inlf antly 

 flow at the wound, although not fo copioufiy as in the early part 

 €>f fpring and fummer. Tlie circulation is alfo either promoted 

 or retarded much by the influence of the climate. 



7. Confiderable quantities both ways.
