This collection of historic maps over the centuries depicts the evolution of Watervliet, New York, from a river plain to an important and early manufacturing center in the Capital District. This fourth volume presents many maps from the 17th to 20th centuries that show the early settlers of the region and the communities they created such as the villages of Washington, Gibbonsville, Port Schuyler, West Troy and finally the city of Watervliet. There is an old saying, A Picture is Worth a Thousands Words, but a map is worth a thousands stories. This is the last of the four volume set on the History of Watervliet, NY.
