1845.  Mrs. Norton, Child Isl. (1846), 131.

        The frozen tombs are sheeted with one pall,—
  One shroud for every churchyard, crisp and bright,—
One foldless mantle, softly covering all
  With its unwrinkled width of spotless white.

1850.  Browning, Xmas Eve & Easter Day, 214.

                  From gap to gap
One hangs up a huge curtain so,
Grandly, nor seeks to have it go
Foldless and flat along the wall.
