F. Wyatt was arrestedinPhiladelphia in September for sending supplies to the South. I know him well and Ihave no doubt that the Governmet got the right man. He is a Virginian, I think from Richmond, bourght up by Jos. R. Anderson, Tredegar Iron Works. He spent the winter of 1859-' 60 in traveling throughthe South spreading the tale that M. W. Baldwin and Mr. Whitney were abolitionists and ought not to receive orders from "true- hearted Soutehrners. " I met him there. He tried by talking against the South todraw me in also but he failed.
