Again, on the 15th May, 1777, Hartley pleaded for us:--
“At sea, which has hitherto been our prerogative element, they rise against us at a stupendous rate; and if we cannot return to our old mutual hospitalities towards each other, a very few years will show us a most formidable hostile marine, ready to join hands with any of our enemies.… I will venture to prophesy that the principles of a federal alliance are the only terms of peace that ever will and that ever ought to obtain between the two countries.”[485]
On the 5th of June, three weeks afterwards, the “Parliamentary History” reports briefly:--
“Mr. Hartley went upon the cruelties of slavery, and urged the Board of Trade to take some means of mitigating it. He produced a pair of handcuffs, which he said was a manufacture they were now going to establish.”[486]
Thus again the abolitionist reappeared in the vindicator of our independence. On the 22d June, 1779, he brought forward another formal motion “for reconciliation with America,” and, in the course of a well-considered speech, denounced the ministers for “headstrong and inflexible obstinacy in prosecuting a cruel and destructive American war.”[487] On the 3d December, 1779, in what is called “a very long speech,” he returned to his theme, inveighing against ministers for “the favorite, though wild, Quixote, and impracticable measure of coercing America.”[488] These are only instances.
During this time he maintained relations with Franklin, as appears in the “Diplomatic Correspondence of the Revolution,” all of which attests a desire for peace. In 1778 he arrived at Paris on a confidential errand, especially to confer with Franklin. On this occasion John Adams met him and judged him severely. In 1783 he was appointed a commissioner to sign the Definitive Treaty of Peace.
These things belong to history. Though perhaps not generally known, they are accessible. I have presented them for their intrinsic value and prophetic character, but also as the introduction to an unpublished letter from Hartley, which I received some time ago from an English friend, who has since been called away from important labors. The letter concerns _emigration to our country, and the payment of the national debt_. The following indorsement explains its character:--
