MAY 21st. — Being in the same room with the Secretary, and seen by all his visitors, I am necessarily making many new acquaintances; and quite a number recognize me by my books which they have read. Among this class is Mr. Benjamin, the Minister of Justice, who, to-day, informed me that he and Senator Bayard had been interested, at Washington, in my “Story of Disunion.” Mr. Benjamin is of course a Jew, of French lineage, born I believe in Louisiana, a lawyer and politician. His age may be sixty, and yet one might suppose him to be less than forty. His hair and eyes are black, his forehead capacious, his face round and as intellectual as one of that shape can be; and Mr. B. is certainly a man of intellect, education, and extensive reading, combined with natural abilities of a tolerably high order. Upon his lip there seems to bask an eternal smile; but if it be studied, it is not a smile — yet it bears no unpleasing aspect.
