Many thanks and appreciation to Mabry Benson for taking all these digital pictures of the 1867 map for the County of Oswego.  C F Stone publ 1867 'New topographical Atlas of Oswego Co'.  It has some nice drawings, and a 16" x 16" page maps of all the townships, maps of villages, and small towns like Colosse, houses indicated &  names of residents of dwellings. 

Most of the pages I had to take in two shots in order to see the names, and then there are all the little villages.  I have cropped out most of the extra, and left some overlap in the towns.  The abreviations in the titles should be obvious - Twn, Vil, NSEW, C for city.
