When Peyton finally reaches the shore, what does Bierce compare the sand to, and what is he trying to say about Peyton's new perspective on life?

As was
mentioned in the previous post, when Peyton Fahrquhar imagines that he is flung onto the
southern embankment of the river, he crawls onto the beach and digs his hands into the sand.
Peyton begins to joyfully throw the sand into the air over his head in celebration,
and Bierce writes that the sand resembles diamonds, rubies, and
emeralds. Bierce is suggesting that Peyton appreciates every small
aspect of life and is simply grateful to be alive. Peyton is then reminded that
he is still not safe when the cannon fires grapeshot at close range. Peyton then dashes into the
forest and eventually walks to his home. On his walk home, Peyton notices the beautiful natural
environment. He is overcome with a feeling of ecstasy and peace as he imagines that he is
reuniting with his wife and children before he dies. Bierce suggests that Peyton has come to
terms with his death and his new perspective on life allows him to appreciate the natural
environment like never before. Peyton becomes aware of the beauty found in the blades of grass,
grains of sand, and constellations as he is standing on the plank awaiting
death.
