THE APPROXIMATION OF AMERICA.
PROGRESS OF SLAVERY IN THE UNITED STATES.
By GEORGE NJ. WESTON. Washington d. &. limo PIP Jul.
This is the production of man who has devoted
much study aud thought to the question of Slavery.
II 10 not sentimental but purely scientific work.
The object aimed at is to discover from the past
history of Slavery the natural laws of its progress
and development, thence to judge with the more
certainty Whist is to be hoped or feared for the
future

On moro or less decidedly ever since the Declawa-
ton Of Independence, Mr.. Weston regards as sub
stsntialy involving the question Of the Afrcaaiza'
ton of America, or it, appropriation to the white
race. So long a. the African slave trade was recog'
njzta 90 q lawful traffic, the immigration to the
New World from the Old was principally African

The number of negroes brought to America had

twenty years ago the African slave trade still brought

t;on. within the last twenty years the tide has
turned, and a large suEual influx Of whites no"
takes place, while the Importation Of Africans has
been greatly diminished. 1t is to this growing
uredominancy of the proportion of the white
regulation that Mr. Weston looks for the extinction
of Slsvery. The Western States have furnished
hitherto an abundant outlet for free labor, which
has not been forced by compression to seek an
outlet Southwark. FIee.lsbOr immigration has
moved Westward parallel to the line OF the
Slave States with little temptation, and, as yet,
scarcely any attempt, to pass the border Hitherto
slave and free labor have scarcely come into.co
fsion and contest except very recently In Kansas
and partially 90 in Missouri. 1t is true that CON
siderable of free labor exist in certain por-
lions Of other Of the Slave States as well as In
Missouri; but these form, as it were, communities
by themselves some counties being cultivated al.
most exclusively by white labor aud others by
slaves As yet even in the Slave States, the two
systems stand apart each with its separate terri
try-Slayery predomiDates in some sections and
free labor 10 others. Nevertheless, the time must
eome with the constant increase of the white popu
Istion, both by natural growth and immigration from
abroad. when an irresistible torrent Of free labor
will be precipitated on the Southern States The

1t cannot be that eight hundred thousand bla'k
slaves should be allowed by their presence in Mary
land, Virginia and Kentucky to exclude five times
that number of intelligent white artisans and far
msrs anxious to emigrate thi,her. Rude labor
must and will retreat before skilled labor whenever
the two come into actual conflict.
The only other Slave State except Missouri in
which any approach toward such a struggle has
hitherto taken place is Maryland. The growth
Of the City Of Baltimore has given great expan.

of that State. Hitherto the weight Of the slave

slave and free, has remained stationary ever since
