PRESENT AND FUTURE OF AMERICA. 



at least two thirds of the agricultural laborers of the 

 United States, would be so destructive to her interest, 

 that no American in heart could countenance it. It would 

 be destructive to agriculture and commerce at the same 

 time. 



However, the other evil is to be guarded against, viz. : 

 the overruning America with a negro race. The increase 

 per cent, of the slaves of the Southern States has been 

 extreme, compared to that of whites ; who, with all the 

 extraordinary immigration in the last 20 years, have not 

 greatly advanced their per cent, over that of the negroes. 

 In 1830, the slaves were as one to five of the whites ; in 

 1850 they are as one to six nearly. During all that 

 time, the amount of immigration of whites has been 

 1,855,643, and that 1,855,613 in the prime of life ; and 

 adding, by their capability to increase and multiply, as 

 well as by their own numbers, a per centage to the white 

 population, that must be far greater than the negro 

 increase. Therefore, their increase could not be less 

 than 30 per cent., which would lower the increase of the 

 permanently settled whites to about 28 per cent, average 

 for the last two decades. 



Therefore, the introduction of slaves, day after day, 

 into Brazils, with the productive powers to propagate their 

 kind, there is every prospect of America becoming seri- 

 ously inconvenienced in some not very distant time. In 

 150 years hence the number of negroes from the present 

 stock of 8,179,589 will be 70,000,000, at the rate of 

 twenty-three per cent, each decade, or at the rate of 

 twenty- three per cent. 128,126,630. The present amount 

 of the race is computed at 55,000,000 in Africa and all 

 other places. If to the increase of the above amount of
