“This case comes up on a writ of error to the District Court for the Northern District of this state. And the question presented for consideration arises out of a special verdict, upon which judgment has been given for the defendant. The result depends entirely upon the construction and location of the deed from Robert Morris to Andrew Craigie, of the 6th of April, 1797, under which the lessors of the plaintiff claims . . . This deed recites an agreement made on the 5th of August, 1795, between the parties, by which Morris covenanted to convey a tract of land corresponding in description with that contained in the deed.”
