Mrs. America expects plenty from us as home economists. All of us who have been in close contact with homemakers for any length of time know that their faith-or maybe more accurately their hopes-as to what we can do for them sometimes seems to know almost no limits. I can well remember the amazement of a staff member of one newspaper home economics department when a voice on the other end of the phone said, "Say, can you tell me what to do to keep a 3-months-old baby's hair from turning red?" Fortunately few worry about this problem.
