To Clear Paperhangings
First blow off the dust with the bellows. Divide a white loaf of two days old into eight parts. Take the crust into your hand, and beginning at the top of the paper, wipe it downwards in the lightest manner with the crumb. Do not cross or go upwards. The dirt of the paper and the crumbs will fall together. Observe, you must not wipe above half a yard at a stroke, and after doing all the upper, part, go round again, beginning a little above where you left off. If you do not do it extremely lightly, you will make the dirt adhere to the paper.
It will look like new if properly done.
