How does cooper introduce the theme of of the decline of Native American culture? How does he continue to build on this as the novel continues?

I don't necessarily find the decline of the Native American culture a major theme in the novel, but Cooper certainly makes us aware of the plight...... beginning with the title. The "Last of the Mohicans." The title is a lamentation for a way of life, and the death of the Indian culture caused by the spread of Europeans throughout North America. The title announces the plot, and the plot details the end of the Native American culture. Cooper specifically cites the Unca's as his subject matter, but in essence is addressing the removal of Native Americans by President Jackson.
