is ground fine, coarse, and medium; and the grinding depends on the way in which it is to be made. For filtered coffee have it finely ground; for boiled, coarse or medium. Filtered Coffee (_French or Percolated_) 1 cup coffee (finely ground) 6 cups boiling water Various kinds of coffee pots are on the market for making filtered coffee. They all contain a strainer to hold coffee without allowing grounds to mix with infusion. Some have additional vessel to hold boiling water, upon which coffee-pot may rest. Place coffee in strainer, strainer in coffee-pot, and pot on the range. Add gradually boiling water, and allow it to filter. Cover between additions of water. If desired stronger, re-filter. Serve at once with cut sugar and cream. Put sugar and cream in cup before hot coffee. There will be perceptible difference if cream is added last. If cream is not obtainable, scalded milk may be substituted, or part milk and part cream may be used, if a diluted cup of coffee is desired. Boiled Coffee 1 cup coffee 1 egg 1 cup cold water 6 cups boiling water Scald _granite-ware_ coffee-pot. Wash egg, break, and beat slightly. Dilute with one-half the cold water, add crushed shell, and mix with coffee. Turn into coffee-pot, pour on boiling water, and stir thoroughly. Place on front of range, and boil three minutes. If not boiled, coffee is cloudy; if boiled too long, too much tannic acid is developed. The spout of pot should be covered or stuffed with soft paper to prevent escape of fragrant aroma. Stir and pour some in a cup to be sure that spout is free from grounds. Return to coffee-pot and repeat. Add remaining cold water, which perfects clearing. Cold water being heavier than hot water sinks to the bottom, carrying grounds with it. Place on back of range for ten minutes, where coffee will not boil. Serve at once. If any is left over, drain from grounds, and reserve for making of jelly or other dessert. Egg-shells may be saved and used for clearing coffee. Three egg-shells are sufficient
