Which sentence in this excerpt from "the open boat" by stephen crane uses personification?
as the correspondent paddled, he saw the captain let himself down to bottom and leave the boat. then the correspondent performed his one little marvel of the voyage. a large wave caught him and flung him with ease and supreme speed completely over the boat and far beyond it. it struck him even then as an event in gymnastics, and a true miracle of the sea. an overturned boat in the surf is not a plaything to a swimming man.

the correspondent arrived in water that reached only to his waist, but his condition did not enable him to stand for more than a moment.
