They used to see it lying on his table, but never saw any signs of his reading it.

At last one winter night late in the senior year something happened which caused a good deal of excitement.
Several of the boys who were down in the yard rushed up in great haste to this classmate's room.

It happened to be unlocked.
They got in without knocking and found him undressed with nothing on but his nightgown.

His bed happened to be near the fire, and standing up on the edge in front of the fire was Bishop Williams's works.
