To “slub” is to pull out and twist a bit of fiber from a wad, in
preparation for spinning it. The twisted lump at the end is also called a
slub. I had previously only known slubs as the little bumps, left over
from the cocoons, that you see on raw silk dresses.
The Pandrol clip is named for its inventor, a guy
named Per Pande–Rolfson.
All the Scandinavian versions of “Peter” are missing the ‘t’: Per, Pehr,
Peer, and Pär. What happened to it?
“Impropriation” is when ecclesiastical property is placed under control
of a layperson. The diary of John Evelyn mentions that the tithing in
some parish was impropriated to his uncle, who then gave £20 per year
back to maintain the church. Why didn't the parish just keep the tithes,
then? (Maybe they came to less than £20? I really don't know.)
