"Major E. L. St. Vrain" and "Capt. Mark Wilton" were both pseudonyms of William H. Manning, according to Patten.(1) If that is true, then two chapters in the composite novel "Jubilee Joe" were written by him. However, that is not improbable, for the publishers may have wished it to appear that the number of authors contributing was greater than it really was. Temporarily, at least, both "Wilton" and "St. Vrain" are here accepted as belonging to Manning. For novels published by Beadle under these names, see Manning.
