Read it through once

I often wanted to kill Brown, but this would not answer. A cub had to take everything his boss gave, in the way of vigorous comment and criticism; and we all believed that there was a United States law making it a penitentiary offense to strike or threaten a pilot who was on duty. However, I could _imagine _myself killing Brown; there was no law against that; and that was the thing I used always to do the moment I was abed. Instead of going over my river in my mind as was my duty, I threw business aside for pleasure, and killed Brown. I killed Brown every night for months; not in old, stale, commonplace ways, but in new and picturesque ones;--ways that were sometimes surprising for freshness of design and ghastliness of situation and environment.
