Clouds/it muft needs hide the Sun from us I as fuch a depth 
faame and Snow would do. But in this Paragraph I would hint 
the change, and bcneficiall Improvement , that may be made 
upon fomeLiquors by meer Frofts, by Chryftallizing , and 
perhaps more by Petrifying Vaults. 
7. lobferv'daSpringj thatinalltheextreameFrofts, that 
have been thefe ten yearSjhath yielded a fmall ftream,which run- 
ning over a large Tradl of Pafture, keeps all the bankes and bor- 
ders Green, and free from freezing , diifolving the Snow, and 
fmoaking all the way where it runs. And this warming force it 
holds for 4 or 5 foot oneachfide^whereverit runs,till the very 
fmall ftream falls into 3 little Chanel. Hence I would offerjthac 
fome better ufe may be made of fuch ftreams for Hortulan En- 
tertainments, and tor many Philofophicalufes, if well confi- 
dered. The Sober Water-drinkers^who are addiftcd to ckan- 
linefs , and a fimple Diet,may by the fmel and taft difcover,and 
fore-warn of the great Diverfitits of waters 5 which are more 
or lefs Petrifying , and which more povverfully diffolving pe- 
crificaDonj which affifts Nutrition, and which is more Jeju- 
ne. Yea perhaps by Afliduity and Inftru<ftions they may Indi- 
cate by Springs , and the fleams of Vaults , much of the Trca- 
fures of our Hills and Mountains 5 and of all the Subterrane- 
ous World. Weirayn up Setting-Dogs to find Partriges, 
but we negledl the Ayd, that may be had from Inquifitive men 
for the finding out of Springs for BoIus's^Salts^Minerals^Stones^ 
and M etals ^ For Health, Accommodations, Ornaments , and 
wealth. You fee here, how by Vaults and deep Wells, furni- 
ftied wiih proper Materials,and fo covered, that by apertures 
wider, -^nd fmaller at pleafure , we may find theeffeds of Air in 
the entrance, and by the rebounding returns,and by mixtures 
with Subterraneous Steams many eififeds , which will hardly ap- 
pear by any contrivance of the Frjeumtk Engine: As to try, 
what the Mineral fleams of all kinds will operate upon all forts 
of MaterialSjWhen they are ftiained by the driving and reboun- 
ding Air through ftrait and winding Orifices of various fliapes, 
wider and narrower :f Whether the Barkes or Timber of Trees 
are snore apt to receive the Saline or other fleams !r And whe-
