I can prove that John Greenleaf Whittier was not the author of the poem you've quoted, "The Pumpkin." It was published two years before it appeared in his first compilation of poetry, in the Oct. 1, 1846 Boston "Chronotype," under the title "Song of the Pumpkin [Written on receiving the gift of a Pumpkin Pie.]," signed "By A Yankee." This poem was written and first published by JGW's younger brother Mathew Franklin Whittier.
