the Places defigned for your Fountains and Water-Spouts : ■ 

 And to k;now what Height thefe Spouts will rifeto^ that if- 

 fue from the Place where you make your Referver^ you may 

 level the Hill according to the following Pra<^tice. 



I SHALL only fliew here the Ufe of a Level, commonly 

 called the Level with Vials, which is the moft exad and 

 plaineft that is. 



'Tis a Pipe of Tin^ about an Inch diameter, and three 

 or four Foot long, as AA^ Fjg. i, ftrengthen'd in the Mid- 

 dle by the Iron 

 Braces B J5, and 

 by the Socket C, 

 which ferves to 

 fix it upon a Stake 

 when you have 

 Occafion tomakfe 

 ufe of it. Upon 

 the upp^r Part of 

 this Pipe, at the^ 

 two Ends^ and in 

 the Middle, are folder'd three other Ends^ of Pipe, which 

 cpmmunicate one with the other, as DEF, and in each of 

 thefe are put the Vials of Ghk ghi, almoft of the fame 

 Diameter, which are open at both Ends, and are joined to 

 the Pipes with Wax or Maftick, fo that the Water rifes into^ 

 the Vials, without lofing itfelf any where. 



Thb Perfedion that has been lately^ given this^ Inftru^ 

 ment, is, that the Middle Pipe E, which is additional, be=- 

 ingout of the Range of thofe two at the Ends D and F 5 

 and being fet of one Side about the fixth Part of an Inch^^ 

 ferves inftead of Siglus, aad direds the, Vifual-Ray much, 

 better. 



To come to the Ufe of this Level, fuppofe the Hill A^ 

 Fig. 2. following, to have on the Top of it aCoUedion of 

 Water in the Referver S, which you would carry to the 

 Bottom of the Hill, as C, to play a Fountain thqre. This 

 k-' the way to level the Hilk 



Set the Level at the Top of the HillAy near. the Edg? 

 of the Referver F^ . as upright as polfible^ and direct it tQ
