A correspondent of the Raleigh Carolinian, writing from Graham, Alamance County, says: Our Court adjourned to-day. The grand jury has been in session all the week investigating the Ku Klux cases. True bills were found to-day in about twenty-five different cases for Ku Klux outrages. There are about seventy-five of the parties indicted in all. Eighteen of these are for the murder of Wyatt Outlaw. A great number of men have taken French leave from Alamance since the commencement of this investigation.
