_Held July 30th, 1619._ INTRODUCTION. The documents herewith presented are printed from copies obtained from the Public Record Office of Great Britain. When the question of the boundary line between Maryland and Virginia was before the Legislature of the latter State, in 1860, Colonel Angus W. McDonald was sent to England to obtain the papers necessary to protect the interests of Virginia. He brought back "nine volumes of manuscripts and one book containing forty-eight maps" (see his report, Virginia Legislative Documents, No. 39, 1861,). The volumes of manuscripts contained, upon an average, 425 pages each, and were filled with valuable historical documents, of many of which no copies had ever been seen on this continent since the originals were sent from the Colony of Virginia. In a conversation with the writer, held soon after his return from England, in March, 1861, Colonel McDonald stated that having obtained copies of all the documents relating to the question of the boundary line which could be found, and having more money left of the appropriation made than was needed to pay the expenses of his return home, he decided to devote the surplus to obtaining copies of papers relating to the early history of the State, without reference to the question of the boundary line. This statement will, we presume, satisfactorily account for the presence in his collection of such papers as do not relate to the subject upon which he was engaged. That he was well qualified to select such papers is evident from an examination of the list which he made out.
