October 5TH.—To-day several Southern-born gentlemen, who have lived long in the North, and have their fortunes and families there, applied for passports. They came hither to save the investments of their parents in Northern securities, by having them transferred to their children. This seems legitimate, and some of the parties are old and valued friends of mine. I know their sympathies are with their native land. Yet why are they so late in coming? I know not. It is for me to send them out of the country, for such is the order of the Secretary of War. The loyalty of the connections of these gentlemen is vouched for in a note (on file) written by Mr. Hunter, Secretary of State. Their names must be published as alien enemies. They will take no part in the war.
