I saw Mr. Benjamin to-day, and asked him what disposition he intended to make of Mr. Custis. He was excited, and said with emphasis that he was investigating the case. He seemed offended at the action of Gen. Winder, and thought it was a dangerous exercise of military power to arrest persons of such high standing, without the clearest evidence of guilt. Mr. Custis had signed the ordinance of secession, and that ought to be sufficient evidence of his loyalty.
