Milde-a is rather a concrete Sub- 

 fhncc, which exfudes thro' the 

 Pores of the Leaves. 



What the Gardeners commonly 

 call Mildew, is an Inle6l which is 

 frequently found in great Plenty 

 preying upon this Exfudation. 



Others fay, That Mildew is a 

 thick clammy Vapour cxhal'd in the 

 Spring and Summer from Plants, 

 Bloflbms, and even the Earth it- 

 felf, in clofe ftill Weather, where 

 there is neither Sun enough to 

 draw it upwards to any conlidera- 

 ble HeifTJit, nor Wind of Force 

 ilrong enough to difperfe it, and 

 that it hanging in the lower Regi- 

 ons, when the Cold of the Even- 

 ing conies on, condenics and 

 falis on Plants, and with its thick 

 clanimy Subftance flops the Pores, 

 and by that means prevents Perfpi- 

 ration, and hinders the Sap from 

 afcending to nourifli their Flowers, 

 Shoots, <^c. 



Others fay, That Mildew is a 

 corrofive or nipping D^w, proceed- 

 ing from the Vapours that are ex- 

 hai'd by the Earth, which being 

 drawn up, and falling down a- 

 gain on the tender opening Buds, 

 inf^As them by its Acrimony, and 

 hinders the Circulation of the nu- 

 tritious Sap in the proper Vcflclsj 

 upon which the Leaves begin to 

 fade, and the Bloflbras and Fruit 

 receive a very great Prejudice. 



Some make this Obfervation, 

 That the Places moil liable to Mil- 

 dew, are inclos'd Grounds and Val- 

 leys, and thofe that lie tending to 

 the Eafl j and the Reafons that they 

 give why thofe Grounds which lie 

 from the Horizon to the Eaft are 

 moil fubjedl to Mildew and Blaji' 

 ings, may be by the Sun's attradl- 

 ing thofe Vapours towards it after 

 the manner that a great Fire in a 

 Room draws the Air to it : So the

Sun having fet thefe in Motiorii 

 and not having Strength enough 

 to draw them into the middle Re- 

 gion, to form them into a Cloudy 

 he does yet draw them till he is 

 below our Horizon, and then thefe 

 Dews tend to the Earth from 

 whence they were exhal'd, and in 

 Motion to the Weft, do, as it were, 

 fall upon that Ground which lies 

 Eaftward at right Angles, and there= 

 fore is moft offenfive to them. 



But I take the true Caufe of tlie 

 Mildew appearing moft upon Plants 

 whi&h are expos'd to the Eaft, tol 

 proceed from a dry Temperature 

 in tJie Air when the Wind blows 

 from that Point, which ftops the 

 Pores of Plants and prevents their 

 Perfpiration, whereby the juices 

 of the Plants are concreted upoa 

 the Surface of: their Leaves, which 

 being of a fweetifh Nature, Infe6ls 

 are inticed thereto, where finding 

 proper Nutriment, they depofite 

 their Eggs, and multiply ^o faft as 

 to cover the whole Surfaces of 

 Plants, and by their corroding the 

 Veftels, prevent the Motions of 

 their Sap 5 and it is very probable 

 that the Excrements of thefe In- 

 re£ts may enter the Veflels of 

 Plants, and by mixing with their 

 Juices may fpread the Infection all 

 over them : For it is obfervable, 

 that whenever a Tree has been 

 greatly affefled by this Mildew^ it 

 feldom recovers it in two or three 

 Years, and many times rlever is in^ 

 tirely clear from it atter^
