A modification of the second method has been adopted by many great speakers, particularly lecturers who are compelled to speak on a wide variety of subjects day after day; such speakers often commit their addresses to memory but keep their manuscripts in flexible book form before them, turning several pages at a time. They feel safer for having a sheet-anchor to windward--but it is an anchor, nevertheless, and hinders rapid, free sailing, though it drag never so lightly.
Other speakers throw out a still lighter anchor by keeping before them a rather full outline of their written and committed speech.
