Lincoln was discussing the Emancipation Proclamation in the summer of 1862, only about 15 months after the south fired on Sumter. Since the total length of the war was in excess of 48 months I hardly think that qualifies as 'late in the war'.
And in it he wrote:
"...the effort to colonize persons of African descent, with their consent, upon this continent, or elsewhere, with the previously obtained consent of the Governments existing there, will be continued."
Perhaps it should be called the "Colonization Proclamation".
