eign to the Indian, while they facilitate in 

 every way the increase of the negro. I infer, 

 therefore, from aU these circumstances that 

 the negro race must be considered as perma 

 nently settled upon this continent, no less 

 firmly than the white race, and that it is our 

 duty to look upon them as co-tenants in the 

 possession of this part of the world. 



Remember that I have thus far presented 

 the case only with reference to the Southern 

 States, where the climate is particularly favor- 

 able to the maintenance and multiplication of 

 the negro race. Before drawing any infer- 

 ence, however, from my first assertion that 

 the negro will easily and without foreign as- 

 sistance maintain himself and multiply in the 

 warmer parts of this continent, let us consider 

 a few other features of this momentous ques- 

 tion of race. Whites and blacks may multi- 

 ply together, but their offspring is never 

 either white or black ; it is always mulatto. 

 It is a half-breed, and shares all the peculiari- 

 ties of half-breeds, among whose most impor- 

 tant characteristics is their sterility, or at least 

 their reduced fecundity. This shows the con- 

 nection to be contrary to the normal state of 

 the races, as it is contrary to the preservation 

 of species in the animal kingdom. . . . Far
