I uploaded Land of the Senecas (1949) by Arch Merrill. It is the story of the Seneca Indians that used to be all over western New York. The book tells of the lore and history before the white man came to western NY. It also tells of famous and infamous leaders. Arch also tells about the early locations of settlements. He then tells about treaties that were made and how some were broken.
The Senecas still have 3 reservations in western NY; Tonawanda, Cattaraugus and Allegany. The Allegany reservation has the Village of Salamanca located on it and people can only lease their property. A yearly rent is paid to the Seneca Nation. All 3 reservations are modern places. Just see their website for all the Nation has to provide to their people. They currently have about 8,000 members with about half of that number living off the reservations.
The Senecas now own three casinos; Seneca Niagara (Niagara Falls), Seneca Allegany (Salamanca) and Seneca Buffalo Creek (Buffalo). The casinos also have dining and some entertainment besides gambling.
I also uploaded the book to the Internet Archive where you can download it in some other formats such as a Kindle version.
