Making the relationship more strained, only months later, Griswold was hired by George Rex Graham to take up Poe's former position as editor of "Graham's Magazine". Griswold, however, was paid more and given more editorial control of the magazine than Poe. Shortly after, Poe began presenting a series of lectures called "The Poets and Poetry of America", the first of which was given in Philadelphia on November 25, 1843. Poe openly attacked Griswold in front of his large audience and continued to do so in similar lectures. Graham said that during these lectures, Poe "gave Mr. Griswold some raps over the knuckles of force sufficient to be remembered". In a letter dated January 16, 1845, Poe tried to reconcile with Griswold, promising him that his lecture now omitted all that Griswold found objectionable.
