I have fixed my eyes on the spaces that heaven's light illuminates, that I may not lay too heavy a strain on the indulgence with which you have accompanied me over the dreary and heartbreaking course by which men have passed to freedom; and because the light that has guided us is still unquenched, and the causes that have carried us so far in the van of free nations have not spent their power; because the story of the future is written in the past, and that which hath been is the same thing that shall be.
