^vhereis the Pumps that are worked by a Horfe are -of very 

 -great Benefit, and furniih a great deal of Water in a little 

 Time- There are fame Pumps afford more Water - in one 

 Hour*s time, than a ^Spring will bring in in four Hours, 

 which is a material Point y befides the Advantage they have, 

 that you may fet them in every Well in your Ground. 



Pumps are diftinguilli'd into two Sorts, that which 

 ■-forces the Water, and that which attrads it j the Difference 

 of which is fufficiently known to every one. 



The fecond way, of raifing Water by Mills that go with 

 the Kelp of the Wind or Water, is infinitely the beft thefe 

 Engines furniihing youalmoft continually with Water, and 

 as one may fay, Day and Night but they are alfo a much 

 more confiderableExpence, and are not proper- for every Si- 

 tuation. 



You muft be near fome River, or Brook, to be ferved by 

 Water-Mills, which in their outfide Form refemble Corn- 

 Mills, and differ only in the Compofition of their Infide, 

 There are fome of thefe Mills that grind Corn, and raife 

 Water when you pleafe, by taking otf the Handle, biu in 

 Places far diftant from Rivers and Streams, as thofe featcd 

 upon fome Hills may be, Wind-Mills do extremely well, 

 the Wind feldom failing in.fuch fort of Situations. Thefe 

 lvlariy',Meu^^ Mills are alfo very like the ordinary Wind-Mills,- but they 

 don, (sndnear have a greater Conveniency, which is that of turning thein- 

 ihcvm^e of ^ i ^ the Wind, by means of a Tail in Form of a Ship's 

 Rudder, which turns about every way. Iheie are a little 

 thefion^ciiL more rare than Water-Mills, having been put in Execution 

 der of Brafs or m thrcc or four Places only ; however, the Excellence and 

 thkhfsmled goodSuccefs of them, may very well warrant any privace 

 ■up and down Gentleman's making the like. 



m the Barrel Qne may fay in general, that almoft all Water-Engincs 

 mThv^'ldVi arereducible to the t Bucket and Sucker, and that they have 

 Bucket, great Conformity with thofe of the Ancients, efpecially that 

 ^■x. X. c. 12. of Ctefibius^ of which Vitnmus makes Mention. 



After having fpoken of the Means of finding out Springs,^ 

 and raifing Water, 'tis neceffary to fay fomcvvhat touching 

 -Refervers, before I proceed to the Manner of conveying it.
