faulkr patTage, to aafwer an enlarging capacity from he top 
to be vented according to that large provifion for delivery ; 
and it fiiews, that Water moves eaficft in Water, and requires a 
conical or tapering liberty throughout for its largeft disburfmene 
sn quantity and eafe in that motion, and the differing fwiftnefs 
makes amends for the difference of the bore for it moves three 
times as faft through the fmaller bore in the fame time^ in anfwer 
to the delivery of the larger bore at the top^ 
It is to beobferved,thac no firength is loft in this oiotion,the 
lateral rubbrngs being prevented thereby, and this being the

in, railing the Water fooner and with greateft eafe.
