Edward Douglass White, Southern Pacific Company v. Pool…
“ Kilpatrick, on its so stopping, at once gave the signal to the engineer to back down, which signal was obeyed, the caboose striking the car with considerable force. In the meanwhile, either on the going forward of Rice or on the stoppage of the caboose, Fowers returned quickly to his work, as did also Pool. As the former stepped under the car, being uneasy lest the caboose should couple, he looked out, and caught sight of a portion of Kilpatrick's body, and say his arm wave the signal to back down. He cried out to Pool, and threw himself from under the car, and was thus saved. ”
