in a twelve Hours Day four Oun- 

 ces, and that without Leaves three- 

 fourths of an Ounce. 



He took another Hop-Vole with 

 its Vines on it, and carry'd it out 

 of the Hop-Ground into a free and 

 open Expofure i thefe imbib'd and 

 perfpir'd as much more as the for- 

 mer in the Hop-Ground: Which is, 

 doubtlefs, the Reafon why the Hop- 

 Vines on the Outlides of Gardens, 

 where they are moft expos'd to 

 the Air, are fliort and poor, in 

 comparifon of thofe in the Middle 

 of the Ground, 'viz.. becaufe being 

 much dry'd, their Fibres harden 

 fboner, and therefore they cannot 

 grow fo kindly as thofe in the 

 Middle of the Ground, which, by 

 Shade, are always kept moifter, 

 and more diidlile. 



The fame curious Author pro- 

 ceeds as foUoweth : Now there be- 

 ing looo Hills in an Acre of Hop- 

 Ground, and each Hill having 3 

 Poles, and each Pole 3 Vines, the 

 Number of Vines will be 9000, 

 each of which perfpiring 4 Oun- 

 ces, the Sum of all the Ounces 

 perfpired by an Acre in 1 1 Hours 

 Day will be 36000 Ounces == 

 iy75'oooo Grains =r, 62007 Cube 

 Inches, or 120 Gallons j whic|i di- 

 vided by 6272640, the Number of 

 fquare Inches in an Acre, it will 

 be found that the Quantity of Li- 

 quor perfpir'd by all the Hop-Vines 

 will be equal to an Area of Liquor 

 fis broad as an Acre, and -^^^ Part 

 of an Inch deep, beiides what eva- 

 porated from the Earth. 



And this Quantity of Moiflure 

 in a kindly State of the Air, if 

 daily carry'd off, is a fufficient 

 Quantity to keep the Hops in an 

 healthy State : But in a rainy moifl 

 State of Air, without a due Mix- 

 ture of dry Weather, too much 

 Moiilure hovers about the Uops^ fo

as to hinder, in ibme meafure, 

 the kindly Perfpiration of the 

 Leaves, whereby the ftagnating 

 Sap corrupts, and breeds mouldy 

 Fen, w^hich often fpoils vaft Quan- 

 tities of flourifhing Hop-grounds. 



This was the Cafe in the Year 

 1723, when for ten or fourteen 

 Days almoft continual Rains fell, 

 about the latter half of July^ after 

 four Months dry Weather j upon 

 which the mofl: flourifhing and 

 promifing Hops were all infe£led 

 with Mould or Fen in their Leaves 

 and Fruit, while the then poor 

 and unpromifing Hops efcap'd, and 

 produc'd Plenty j bccauie they be- 

 ing fmall, did not perfpire fo great 

 a Quantity as others j nor did they 

 confine the perlpired Vapour, fb 

 much as the large thriving Vines 

 did in their fliady Thickets. 



The Planters obferve, than when 

 a Mould or Fen has once {eiz,'d any 

 Pirt of the Ground, it foon runs 

 over the Whole, and that the Grafs 

 and other Herbs under the Hops 

 are intedled with it \ probably, be- 

 caufe the fmall Seeds of this quick- 

 growing Mould, which fbon come 

 to Maturity, are blown over the 

 whole Ground ; which fpreading 

 of the Seed, may be the Reafon 

 why fbme Grounds arc infedled 

 with Fen for feveral Years fuccef^ 

 lively, liz,. From the Seeds of the 

 lad if ear's Fen. Might it not then 

 be advifeable, to burn the Fenny 

 Hop-Vines zt fbon as the Hops are 

 pick'd, in hopes thereby to de- 

 f^roy fome of the Seed of the 

 Mould ?
