Chap. IX. of Gardening. ipj 



Reservers may be diftingiiilhM into two Sorts, thofe 

 that are made upon the Ground, and thofe that are raifed a- 

 loft in the Air* 



The Refervers that are upon the Ground, are ordinarily 

 Bafons of Water, or Canals done over with Clay, where 

 the Springs are colleded, and which hold many thoufand 

 Hogllieads of Water. They are ufually made pretty deep^ 

 as well that they may hold the more Water, and not empty 

 themfelves fo foon, as to add the greater Weight to the Wa- 

 ter in Pipes, and throw the Spouts the higher. When you 

 can place them in your Park, and within your own Bounds, 

 'tis certainly bed , but when that can't be done, you may 

 make them without in the Fields, inclofingthem with Walls. 

 In Gardens that are floping, the Balbns above ferve for Re- 

 fervers to the Water-works below, which is a great Ad- 

 vantage. 



The Refervers that are railed aloft, are nothing near fo 

 large and capacious, the biggeft holding no more than five 

 or fix hundred Hogftieads of Water, and are very feldoni 

 of this Size. They generally contain no more than a 

 hundred or two hundred Hogiheads. The Difficulty of 

 fuftaining them, and the Charge of Lead they are covered 

 with, doth not permit to make them fo big as thofe that 

 are upon the Ground. They are fet up upon Arches, or 

 Pillars of Free-fl:one, upon which are laid great Scant- 

 lings of Timber-work framed together, to fupport the 

 Bottom and Sides, which fliould be carefully lined with 

 thick Sheets of Lead foldered together- The Founda- 

 tions and Timber-work of thefe Refervers ought to be 

 very fubliantial, to be able to fuftain the great Weight of 

 Water, ^ ^ 



There are more of thefe raifed Refervers to be feen 

 •than of the others, becaufe thofe that have Water-Engines 

 cm fcarcely build any others, by reafon of the flat Situa- 

 tion of their Ground. 



The next Thing I am to fpeak to, is that of conveying d'Eau'^Ir^ 

 the Water from thefe Refervers, to the Bafons for the play- jiich Spoias as 

 ing of Jets, Water-Spouts, and Cafcades. " ihrow tb.^ iva^
