 Context examples 

He went straight over to the window and brushed out the crumbs of sugar; then he took his fly-box, and emptied it outside, and threw away the box; then he shut the window, and crossing over, sat down on his bed.

(Dracula, by Bram Stoker)

This frightened him dreadfully, and away he ran to the back door; but there the dog jumped up and bit him in the leg; and as he was crossing over the yard the ass kicked him; and the cock, who had been awakened by the noise, crowed with all his might.
