OX-TAIL SOUP

One ox-tail, two pounds lean beef, four carrots, three onions, parsley, thyme, pepper, and salt to taste, four quarts cold water. Cut tail into joints, fry brown in good drippings. Slice onions and 2 carrots and fry in the same, when you have taken out all of the pieces of tail. When done tie the thyme and parsley in lace bag, and drop into the soup-pot. Put in the tail, then the beef cut into strips. Grate over them two whole carrots, pour over all the water, and boil slowly four hours; strain and season; thicken with brown flour wet with cold water; boil fifteen minutes longer and serve.
