Henry James on Melville

Henry James?
Are you sure?

So sorry, the question was actually "What were his views on Melville's highly experimental fiction". And I do mean Henry James, William James's younger brother. I haven't been able to find any references in the biographies & criticism so far. This strikes me as odd, since James was a voracious reader, and even hailed new talent such as Marcel Proust before he passed away. Did he burn his views along with the letters in his bonfires, perhaps?
