Place any amount of paper (filtering paper is not necessary, though it is the best) in a mortar, or other vessel, upon which pour enough solution of soda or potassa to very thoroughly wet it; stir it with a pestle or stick until it is reduced to a pulp, which will only take a minute or two, then add cold water; stir, throw upon a calico filter, let drain, and wash with water until all traces of the alkali are washed out. By this process any amount of pulp can be prepared in a very short time, and can be put into wide-mouthed bottles for future use.
