Correspondence of Gov. Horatio Sharpe, 1754-1765. 533

of the Rolls dismissed his Bill of Equity about Maryland,
intermixed with common Law and his false Plea about his
Tryal at Croydon Assize, he returned him to common Law,
where I Outlawed him; he has still another Bill in the Court
of Chancery about Maryland, which I have no doubt of
dismissing the ensuing Term. The reason of my writing
about the Mannor called Lady Baltimore was because he had
propagated the Cause of his not being in Possession was my
having dispossess'd his family and him by my orders; he's
of no import and his ways are Base ingratitude.

Yours of the 12^th of September last, gives me pleasure of
the arrival of the Sector, Telescope, and Apparatus for the
Sector and of the Brass yard and measuring Instrument,
and in the Box was a Silver Medal of his present Majesty
by you not mentioned. With regard to Method of running
Boundary Lines, inclosed, is Dr. Bevis's a Skilful Mathe-
maticians Judgement and prescriptions, 'tis really out of
my Ken. Concerning the Doctor's Transit Instrument for
running such Lines; I did all to Obtain it. But M^r Thomas
Penn* to all that is proposed on Lord Baltimore's side with
him takes not. The Instrument was mounted, and several
Mathematicians were with his Lordship and M^r Penn pres-
ent, and the Instrument displayed by the Doctor, I thought
and others there acknowledged the real Utility was suffici-
ently proved, what then, M^r Penn and his followers Hum-
buged it? My Lord offered jointly with Penn to purchase
it, he refused; I endeavoured for his Lordship to purchase
it for his own Use, which he declined, it would a been of
General use for Surveys and running limits. Since M^r Penn
has been at much greater Expence, he has had a Six feet
Sector constructed by M^r Bird a famous Mathematician In-
strument maker, Attendant the Apparatus, said with Accu-
racy; it has a fine Aspect in Construction, and is the same you
have received, perhaps may better Answer, if not prevented
by Accidents from Carriage or from Hot and wet weather.
Concerning the Meridian Head of Potowmack River I wrote
you, 'tis of the greatest Consequence How determined? I
have received a Letter from Mr. Cresap in Maryland, he
says, Concerning "the North Branch of Potowmack River, I
find that the South Branch is about Eighty Miles longer than
the North Branch, which runs South thirty four degrees to
the West from the mouth forty Miles or upwards on a
Streight Line and then turns and runs West about fifteen
Miles when it makes a Fork, where Lord Fairfax's Line
crosses to the Fountain Head of the North Branch, But the
South Branch after his Lordship's Line Crosses, it continues
