Weekend Cooking: P.R. SOUP

1 head celery, 4 large tomatoes, 4 qts. water, 4 large English onions, 3 tablespoons coarsely chopped parsley.

This soup figures often in the diet sheet of the Physical Regenerationists for gouty and rheumatic patients, but in addition to being a valuable medicine on account of its salts, it is the most delicious clear soup that I know of. To make: chop the ingredients to dice, cover closely, and simmer until the quantity of liquid is reduced to one half
