The M & M ("Dr. Webb's Railroad") was the result of an 1892 merger between the St Lawrence & Adirondack and several railroads based in Herkimer. It was in turn taken over by the New York Central in 1913 as their Adirondack division. (The http://www.townofrussia.com/railroads.html website has a detailed history of this region that demonstrates just how complex and devious railway development could be.)
