Question

how does chief Seattle conclude his speech

Answer 1

He concludes in a way that looks like he's snapping the 'pale white faced children'. He says death does not occur to his kind, for his ancestors' spirits still roam their soil and will until the end of time. He says, only change of the worlds occur to his people, for his people's God, 'The Great Spirit', is liberal and generous. He doesn't let his children forget their pasts.

(P. S. - Wish I were there to see their pale faces when Seattle concluded his speech!)
