Famous quotes containing the words roll and/or bar:
“Let us have a good many maples and hickories and scarlet oaks, then, I say. Blaze away! Shall that dirty roll of bunting in the gun-house be all the colors a village can display? A village is not complete, unless it have these trees to mark the season in it. They are important, like the town clock. A village that has them not will not be found to work well. It has a screw loose, an essential part is wanting.”
—Henry David Thoreau (1817–1862)
“They made a paction tween them twa,
They made it firm and sure,
That the first word whaeer shoud speak,
Shoud rise and bar the door.”
—Unknown. Get Up and Bar the Door (l. 13–16)
