—We notice now, as the most recent movement, that a State convention of the Mississippi Colonization Society, held a few weeks since, to consider the project of emigrating from the South, was attended by some 4,000 persons, including 300 delegates from other States than Mississippi. The proposition to emigrate to Africa was not looked upon with favor, but the proposition to emigrate to Arizona, New Mexico or Texas was approved. The following resolution was adopted:

Resolved, By the people of color of the State of Mississippi, in convention assembled, that we earnestly entreat our countrymen throughout the Union to form a national colonization association, with branches in every county and State in the Union, for the purpose of effecting a peaceable separation of the blacks from the whites, and concentrating our numbers as a body in certain States or Territories within this Union, as may be hereafter agreed upon in national convention assembled.

A national convention is to be held in February next, at Corinth, Miss., in furtherance of this project.


INDIAN NOTES.

—Are the Indians dying out? Major S. N. Clark, of the Bureau of Education, has compiled these various estimates of their population as follows:

1789—Estimate of Secretary of War76,000
1790-91—Estimate of Gilbert Imlay60,000
1820—Report of Morse on Indian Affairs471,036
1825—Report of the Secretary of War129,366
1829—Report of the Secretary of War312,930
1834—Report of the Secretary of War312,610
1836—Report of Superintendent Indian Affairs253,464
1837—Report of Superintendent Indian Affairs302,498
1850—Report of H. R. Schoolcraft388,229
1853—Report of United States Census of 1850400,764
1855—Report of Indian Office314,622
1857—Report of H. R. Schoolcraft379,264
1860—Report of Indian Office254,300
1865—Report of Indian Office294,574
1870—Report of United States Census313,712
1870—Report of Indian Office313,371
1875—Report of Indian Office305,068
1876—Report of Indian Office291,882

These figures are, however, in part conjectural, and all based upon varying data, and limited by varying boundaries. They do not show any constant movement of increase or decrease.

In regard to particular tribes, the Cherokees, since 1809, notwithstanding the depressing influences of removal, and loss by civil war, have increased from 12,395 to 21,072. The Seminoles have, since 1870, increased from 2,638 to 3,000. The Iroquois, 100 years ago numbering about 11,500, are now 13,668. Within forty years the Sioux are computed to have increased from 25,000 to 40,000.

A comparison of births and deaths for the last three years has been made, but it is too incomplete to be the basis of any conclusions.
