We cannot quit Philadelphia without making mention of the acts of congress. It has been resolved to confiscate the property of the subjects of Great-Britain, taken on the high seas, or between high and low water mark, but the inhabitants of the Bermudas, and Providence or Bahama Islands are excepted. General Washington has been empowered to agree to the exchange of governor Skeen for Mr. Lovell, who was made close prisoner at Boston by order of general Howe; and to whose inflexible fidelity to his country, congress bore testimony the beginning of January. Mr. Lovell contrived to send out intelligence to the Americans, while investing Boston; and the reasonable suspicion of it, without positive proof might occasion his confinement. Commodore Hopkins, has been censured for not paying a regard to the tenor of his instructions, which directed him to annoy the enemy’s ships upon the coasts of the southern states; and his reasons for not going from Providence immediately to the Carolinas, have been declared by no means satisfactory. To prevail on the foreign officers, if possible, to quit the royal army, congress have proposed, upon their choosing to become citizens of the states, to give to them and their heirs in absolute dominion, unappropriated lands in the following proportions: to a colonel, 1000 acres; to a lieutenant-colonel, 800; to a major, 600; to a captain, 400; to a lieutenant, 300; to an ensign, 200; and to every non-commissioned person, 100. They complied with general Howe’s proposal of exchanging general Sullivan for general Prescot, and lord Stirling for gen. M’Donald, on the 4th of September.
