To clear a wall from paper previous to painting or white-washing it, wet the old paper thoroughly with a long-handled brush dipped in a bucket of water, (warm water is best.) Let it rest till the water has penetrated it, and the paper blisters and loosens, so that you can peel it off with your hands. Do not wet too much at a time. If any small bits are found still adhering, wet them afresh, and scrape them off with a strong knife.
If you intend papering a painted wall, you must first get off the paint, otherwise the paper will not stick. To do this mix in a bucket with warm water a sufficient quantity of pearlash, or potash, so as to make a strong solution. Dip a brush into this, and with it scour off all the paint, finishing with cold water and a flannel.
