may be made feverall receptacles above cue another 
to receivQ the rais'd water, fo as doch the Crown \Fiv 
and there fiiould be as many bellows to communicate 
every one with one receptacle : thefe bellows fliould 
be moved by an ^xis, fo that when the firft is open, 
the fecond Ihould be fhut^- the third open, the fourth, 
fliut i and fo forth alternatively ; which may be eafi- 
ly done: by this means, the firft or loweft receptacle 
would give the neceffary fupply of water to the fecond, 
the fecond to the third, the third to the fourth, &c* 
till the water would be rais'd to the intended height; 
fuch receptacles might eafily be fet twelve or fifteen 
foot above one another, and fo but few of thcm might 
raife water to a confiderable heighth , as well as 
ordinary Pumps do ; but this new way would have this 
advantage, that in the ordinary pumps the ftrength 
to.be applyed lyeth near the vi^ater to be raifed, but 
by this contrivance the ftream of a River may be ap- 
plyed to draw water out of a mine far diftant from it ; 
by the lame way the ftream of thcThames might keep 
conftant wsLter works mWind/or-Cafile ^ as eafie almoft 
as in the loweft fields: the River Seine might do the 
fame at S'. Germain^ and perhaps at Verfailles too, 
notwithftanding the great diftance : for it is to be ob- 
served, that the Pipes of communication between 
the bellows and Engine, being meerly for the convey- 
ing of the Air^ which moves very fwifcly, they may be 
flender enough, andfo contain but a fmall quantity of 
Air xo be rarified 5 and befides they will not be fubj^6t to 
burft or leak, fince the prefTure they bear,being allexter- 
nall to the Pipe, will rather ftrengthen then br^ak 
the fame : fr^m whence it follows, that the lay'd Pipes 
need not be ftrong, but may be made at very fmall 
charges. It is alfo to be obferved, thatthofe bellows, 
that are open, have the in them very much rari- 
Jied, fo that the outward ^/r lyeth heavy u^pon (^^ 
them^
