This would make the value of the labor of this million of immigrants, in ten years, $550,000,000, independent of the annual accumulation of capital, and the labor of the children of the immigrants after the first ten years, which, with their descendants, would go on constantly increasing. But, by the actual official returns (see page 14 of Census), the number of alien immigrants to the United States, from December, 1850, to December, 1860, was 2,598,216, or an annual average of 259,821, say 260,000. The effect, then, of this immigration, on the basis of the last table, upon the increase of national wealth, was as follows: 1st year 260,000 = $26,000,000 2d " 520,000 " 52,000,000 3d " 780,000 " 78,000,000 4th " 1,040,000 " 104,000,000 5th " 1,300,000 " 130,000,000 6th " 1,560,000 " 156,000,000 7th " 1,820,000 " 182,000,000 8th " 2,080,000 " 208,000,000 9th " 2,340,000 " 234,000,000 10th " 2,600,000 " 260,000,000 ------------ Total, $1,430,000,000
