Both were famous abolitionist in the U.S. although Garrison was white and Douglass was black. They were also close friends and co-workers in the American Anti-Slavery Society up till 1850 when bills for the Compromise were passed.
Garrison to Douglass: with California joining as a free state, we may soon have sufficient support to overturn the Constitution and write a new one. I hope it will be done in a peaceful manner though.
Douglass to Garrison: the founding fathers did not see slavery as a long term phenomenon here; just as Washington DC is ending the slave trade now. We do not need a new Constitution but there may be conflicts when slavery is abolished.
