The proprietary's next territorial controversy had a greater duration, and a less fortunate issue, being prolonged nearly a century, and resulting in the dismemberment of a portion of his fairest and most fertile territory. It must be mentioned, that the charter of Maryland extended its northern boundary to the southern limit of what was then called New England. In the intermediate territory between the actual settlements of the two, the Dutch and the Swedes had planted some colonies and trading-houses on the banks of the Delaware Bay and river, in what is now the state of Delaware. The Swedish establishments were reduced by the Dutch in 1655, and appended, together with their own, in the same quarter, to the government of New Netherlands; on the English conquest of which, and the grant of them by Charles II. to his brother, the Duke of York, the settlements on the Delaware became dependencies on the government of New-York, and, though clearly within the limits of Maryland, being south of the latitude of 40°, remained so until the grant to Penn, and the foundation of Pennsylvania in 1681. The southern boundary of Penn's grant, was somewhat loosely established to be "a circle of twelve miles drawn round New Castle, to the beginning of the fortieth degree of latitude." Penn was eager to adjust his boundary with Maryland; but when it was found, on an interview between his agent and Baltimore, at Chester, then called Upland, that Chester itself was south of the required latitude, and that the boundaries of Maryland would extend to the Schuylkill, he very earnestly applied himself, to obtain from the Duke of York, a grant of the Delaware settlements mentioned above. In contravention of the claims of Baltimore, a conveyance was made to him in 1682, of the town of New Castle, with the district twelve miles round it, and also of the territory extending thence southward to Cape Henlopen.
