192 PRESENT AND FUTURE OF AMERICA. 



that the increase on large populations never keeps pace 

 with that on smaller populations, the calculation of 25 

 per cent, is not under what the increase may be in some 

 years hence ; and if it be under it for the next 100 years, 

 it will be as certainly over it for the following 50 years 

 of the tabular calculation annexed. 



The free colored population will most likely not keep 

 its place as a class. The proportion of white males 

 and females will be for the future more equal than it has 

 been heretofore ; and probably the female will prepon- 

 derate over the male population ; and, consequently, 

 there will be more marriages, Und less intercourse 

 between the two races, between whom there is such 

 wide difference, as an Irishman would say, in flesh and 

 blood. The last ten years their increase has been only 

 14 per cent. I have calculated it, all through, at 15 per 

 cent. 



SLAVERY. 



The slaves I have calculated throughout from 1850 at 

 23 per cent. From '30 to '40 it was 23 J per cent.; from 

 '40 to '50, 27* per cent. If they do increase at the rate 

 of 27 per cent, they would be likely to gain numerically 

 after some years on the white population. However, 

 taking it at 23 per cent., it will be seen that the num- 

 bers of slaves, or negroes, will become excessively great. 

 Their increase is much less likely to be interrupted than 

 that of the whites. As slaves, they will be kept at 

 home, cared for, and suffer no diminution in war or on sea. 

 Upon the white population, all that drain of men will 

 fall, as well as the drain from dissipation arid intern-
