Point XXXIII.

Engineers, and makers of Fire-works, may perform many wonderful things, by the help of this Subject.

That common Nitre is used in the making of Gun-powder, and other Fire-works, wants no Testimony, being a thing every where known.

Many new Works belonging to the Weavers, and Smiths Art, may be made thence, which may be Communicated to Neighbouring Countries, in lieu of which, money may be brought into a Country impoverished by War.

As for this point, it is most certain, that by the mentioned Subject, various Manufactures may be perfected, which thing let no Man doubt; but there is no need here to particularize; let it suffice that I have verified (by the assistance of God) those things which I have named, and proposed to explain in that place.
