May it please Your most Excellent Majestie.
This containes Your Majestie's grant unto Jacob Rowe, of the city of
London, Gentleman, his executors, administrators, and assignes, of the sole
use and benefit of his new Invenčon of pumping water without the least
friction, or the suckers touching the sides of the pump, the avoiding of
which friction will, in a great measure, lessen the want of the usuall powers
in raising water, to obviate which he hath applyed a power, by means of a
screw contrived suddenly to fly up and down, whereby several pumps with
little labour and small charges may be worked at one time, tending very
much to the advantage of Your Majestie's subjects, and also the sole use and
benefit of his new method of exhausing air out of vessells, or making a
vacuum, causing thereby a sudden rise of water, in such a manner and in
such a quantityes as will appear to be entirely new, to hold and exercise the
same, within England, Wales, and town of Berwick-upon-Tweed, for and
during the term of fourteen years, according to the statute in- such case made

page_text: and provided, and such clauses, powers, provisoes and restricčons, are inserted
as are usuall in grants of like nature, and as were directed.
By warrant under Your Majestie's Royal Sign Manual, countersigned by
P. YORKE.
