  SINCE ATMOSPHERIC PRESSURE DECREASES AS ALTITUDE INCREASES, THE
  REQUIREMENT FOR BAKING SODA ALSO DECREASES.  BAKERY MIXES ARE
  FORMULATED FOR USE AT SEA LEVEL AIR PRESSURE.  A REDUCTION IN THE
  SODA CONTENT OF MIXES AT HIGHER ALTITUDES IS EASILY ACCOMPLISHED WITH
  MIXES CONTAINING A SEPARATE SODA PACKET.  IF THE SODA PACKET IS NOT
  LABELED WITH INSTRUCTIONS FOR THE AMOUNT OF SODA TO BE USED AT
  DIFFERENT ALTITUDES, USE THE FOLLOWING AS A GUIDE: 2000 FEET --- USE
  80 % (4/5 OF PACKAGE) 4000 FEET --- USE 66 % (2/3 OF PACKAGE) 6000
  FEET --- USE 55 % (1/2 OF PACKAGE) 8000 FEET --- USE 35 % (1/3 OF
  PACKAGE) WHEN PREPARING CAKES, HOT BREADS, AND DROP COOKIES FROM
  BASIC INGREDIENTS AT HIGH ALTITUDES, QUANTITIES OF LEAVENING AGENTS
  MAY BE ADJUSTED AS SPECIFIED IN THE TABLE ON THE BACK OF THIS CARD.
  CAKES HAVE A TENDANCY TO STICK TO PANS AT HIGHER ALTITUDES;
  THEREFORE, THE PANS SHOULD BE GREASED AND DUSTED MORE HEAVILY THAN
  THOSE USED AT SEA LEVEL. OVEN TEMPERATURES SHOULD BE INCREASED 25
  DEGREES F. AT ELEVATIONS OF 3500 FEET OR MORE.  THE BAKING TIME IS
  GENERALLY THE SAME AS AT SEA LEVEL; HOWEVER, CARE SHOULD BE TAKEN TO
  AVOID OVERBAKING SINCE EVAPORATION RATE INCREASES AT HIGHER
  ALTITUDES. BAKING POWDER OR BAKING SODA IN RECIPES FOR CAKES, HOT
  BREADS, AND DROP COOKIES PREPARED AT HIGHER ALTITUDES SHOULD BE
  DECREASED AS FOLLOWS:
