A friend and reader emails this, re the old Wellfleet place we posted a couple of weeks ago:
I've been in a bunch of really old shacks down that way. The people that built them were really amazingly flinty and resourceful. I've attached a picture of a threshold of a door from Truro. They couldn't manage to have a door sweep, so they made a sort of rain gutter with a drain hole in the nose. You know how the rain comes at a house down there. There was never any overhang in those old houses, so the rain sheeting down the door would probably flood the floor, and some poor bastige named Higgins or Crowell or Snow or Starbuck got it off the honeydew list as best he could. Marvelous.
