Inch Diameter the fame Height as it lies a- 

 bove the Surface of the Fountain : If there- 

 fore you would have it to play higher, you 

 muft make the Bore or Spout of your Pipe 

 the lefs ^ or if you would have the Body of 

 Water the bigger, you muft expeft it will 

 play ftill the lower: And the better Per- 

 formance of this will depend on the Largenefs 

 of the Grand Pipe or Body of Water that 

 lies ready from the Grand Referve for this 

 Purpofe. But the farther Account of this 

 Ihall be the Work of fome enfuing Treatife 

 (if Providence gives me the liberty of Going, 

 and a fafe Return from Abroad.) 

 Their Con- It has been always the Method of Stoning 

 ^J^"^!"" ^ or Bricking, and fometimes Leading the Sides 

 ecuri y. ^^ Fountains, Canals, and Ponds 3 but in 

 this refped there is fo much Money buried, 

 that I cann t but advife Gentlemen to confider 

 if there are no nearer Methods. Thefe 

 Walls are generally made of Stone or Brick, 

 and clay'd well behind, to keep the Water 

 from finding its way thro' the Sides ^ or by 

 Lead both m the Sides and Bottom, which is 

 very chargeable, fcarce advifeable to be us'd 

 any where but in Derbypire^ or other Coun- 

 tries where Lead is in great plenty, and the 

 Carriage near. Perfons of Quality and Gen- 

 tlemen that have large Plantations, ought to 

 be well aware what Money they bury 

 under Ground, when they have fo great a 

 Space of Ground to furnifh and embellilh a- 

 bove : And tho* fuch Expences be but 100 /.
