A Venule foldisr from Maine.The Richmond Examiner has tbs follow-- * .ing account of the discoverj soldier, a member of the 16th Maine Regiment, id prison at Richmond:Yesterday a rather prepossessing'look* iog lass was discovered on Belle Isle, disguised, among the prisoners of war held there. She gave her real name as Mary Jane Johnson, belonged to the 16th Maine regiment, and had been a prisoner some time. She gave as ao excuse for adopting her soldier toggery, that she was following her lover to shield and protect him when | in danger. He bad beea killed in battle, j and now she would have no objection to return to the more peaceful sphere for which nature, by her sex, had better fitted her. The heroine of a novel yet to be written in Yankeedom was considerably sunburned and roughened by the hard-\ ships she had encountered, but still retained marks ot some womanly comeliness, which would be highteoed by a calico frock and crinoline. Upon the discovery of her 6ex, Miss Johnsoo waa removed from Belle Isle, and is now confined at Castle Thunder. She will probably go North by the next flag cf truce. She is about nineteen years of age.— i ■ ■ _
