"Oh, Dickens! the Atlantic was thy Rubicon; on its broad waste thou didst shipwreck much Fame and Honor. Wonderful indeed that thou shouldst, in a day, turn two millions of admirers, firiends, into despisers! Whilst the arms of millions were outstretched to receive thee, and their eyes glistened with welcoming pleasure, in thy heart thou betrayedst them, and sold them to a publisher!" 
(September 1851, Scenes Beyond the Western Border; and
Scenes and Adventures in the Army)

Melville's sister Helen got to meet Dickens in Boston.

"A great admirer of Charles Dickens, Helen wrote Augusta that she had shaken the hand of 'the great Boz' when he visited Boston in 1842, and she would never wash that hand again."

Melville and Women, 19)

"She  had not only shaken Charles Dickens’s hand, in February 1842, she had been granted a private visit with the Shaws in to the studio of Francis Alexander, the official painter of Dickens in Boston...."
