In a 1970 letter to Brainard, James

Schuyler explains:
As soon as I got here I started to make you a trash book out of
an address book I had never used. I thought it would take about
an hour, but who would guess that an address book, such a
little itty bitty address book, could have so many pages? Or that
one’s trash runs out so soon? A trash book, in case you’re wondering,
is something like a scrap book, only, well, you put trash
in it. Which is not the same as garbage. That you put in boxes,
like a candy box, and call it a Garbage Box. Garbage Boxes are
not quite so nice as Trash Books. (Just the Thing 298)
