to grow very fad, during theSum- 

 mer-feafon j but they feldom endure 

 the Winter in iiich Soils. The 

 Double-flower'd Plants of this 

 Kind may alio be propagated by 

 Slips, in the lame manner as the 

 before-mention'd Sorts ; but thefe 

 fhould be flielter'd in Winter, as 

 was diredted for the white fF^//- 

 jiovoer, otherwife they are fubje£t 

 to be kill'd by very flrarp Frolls. 

 The Seeds of this Kind fhould be 

 often chang'd, or elfe they will 

 greatly degenerate. 



The old Double Bloody Wcill- 

 floTocr was formerly more common 

 in EngUnd t\i2,n at prefent, it being 

 at this Time rarely to be fcen: This 

 is a Variety of the common Double 

 IVall-Jlorpsr^ from which it only 

 differs in having the Outlide of the 

 Petals of a Bloody Colour ; It may 

 be propagated by Slips, as the com- 

 mon Sorti but requires to be fliel- 

 ter'd from extreme Cold in the 

 Winter, which often deftroys thele 

 Plants if they are too much expos'd 

 to it. 



Tlie Yellow-ftrip'd mdl-flovoer is 

 alfo a Variety of the common 

 Double Sort, having its Leaves 

 beautifully variegated in the Spring 

 and Winter-fcafon i but in the Sum- 

 mer, when the Plants are very free 

 of Growth, they degenerate to be 

 almoft quite plain, lb that at that 

 Seaibn there is very little Beauty in 

 them : This is alio propagated by 

 Slips, as the Common Sort 5 but 

 fliould be planted in a warm Situa- 

 tion, otherwife it will often fuffer 

 by great Colds in Winter. 



The Silver-ftrip'd WcJl-fiower is 

 much more beautiful than the laft, 

 and generally retains its beautiful 

 Variegation through the whole Year. 

 This is propagated by Slips, as the 

 tormerj but Ihould be flielter'd in 

 Winter, being much tenderer than

the lafl: ; for which Reafon, the 

 Plants fhould be fet into Pots, and 

 treated as the Double White Wall- 

 flower : but you fhould obferve, 

 never to plant them in a rich Soil, 

 which will caufe them to become 

 plain, (as I have often obfervM) nor 

 ihould they have too much Moifture, 

 which very often deftroys 'em. 



All the Sorts of Wall-flowers will 

 abide the Cold much better if plant- 

 ed in a very gravelly and Ifony Soil, 

 than when they are in a rich Earth, 

 as may be obierv'd by thofe v/hich 

 grow upon the Tops of Walls, and 

 other Buildings, where fomctimes 

 they are very much expos'd to the 

 cold Winds, and yet often endure 

 the fliarpeft Winters ^ when thofe 

 which were planted in a good Soil 

 have been deftroy'd, notwithftand- 

 ing they have a warm Situation. 



LEVEL, a Mathematical Inllru- 

 mcnt ferving to draw a Line pa- 

 rallel to the Horizon, not only for 

 various Ufes in Malbnry, (Qrc but 

 alfo to meafure the Difference of 

 Aicent and Delcent between leve- 

 ral Places, for the Conveying of 

 Water, Draining of Fens, c^r. 



A Water Level Ihews the Hori- 

 zontal Line, by means of a Surface 

 ot Water, or other Liquid, founded 

 on this Principle, that Water always 

 naturally places itlelf /^^v«/. 



The moft limplc Inftrument for 

 this Ufe, is made of a lont? wooden 

 Trough or Canal whofe Sides are 

 parallel to its Bafe,- fo that being 

 equally fiU'd with Water, the Sur- 

 face thereof Ihews the Line of 

 Level. 



This Level is alio made with two 

 Cups fiU'd to the two Ends of a 

 Pipe three or four Feet long, about 

 an Inch in diameter •■> by means 

 whereof, the Water communicates
