The message *is* correct.

Since the "public" qualifier is used in the inheritance, the members of
"higher" can only access the public members of "bottom". This restriction
also carries over to any friends of the derived class.

What Mike needs to do to make this do what he wants is to declare "higher"
as:

  class higher : bottom {
   ...
  }
