Professor Tucker, another ex-congressman, in a work published in 1843, says, commenting on Seybert’s estimate, “Since an account has been taken of the foreign immigrants who arrive in our seaports as well as from the intrinsic evidence afforded by the enumerations themselves, we must regard his estimate as much too low.” Tucker admits that “our estimates of the whites who migrated hither before 1819 are purely conjectural,” but yet he adopts Seybert’s estimate of 6,000 a year from 1790 to 1810—a total of 120,000—and assumes that from the last named year until 1820, 114,000 immigrants arrived, thus making the total number who came here between 1790 and 1820, 234,000. He, however, remarks in a note that he could not go beyond this estimate “on account of his respect for Dr. Seybert’s opinion,” but he “could not give a less number because of his regard for the progressive increase of immigration before and after the three years of the war of 1812–1815.” J. D. B. DeBow, superintendent of the census of 1850, in one of his volumes published in 1854, relies on Prof. Tucker’s estimates for the number of those who arrived here during the thirty years preceding 1820, while W. J. Bromwell of the state department, writing in 1856, raises the number to 250,000. It will be observed that these “estimates” are in fact merely conjectures, and that in the only year (1817) during the entire period from 1790 to 1820 for which actual figures are given, the returns from only ten ports show the arrival of more than twice the average annual number of immigrants estimated by the writers above referred to. It seems, then, evident that the immigrants from 1790 to 1820, and particularly those of Irish birth or blood, were much more numerous than the writers quoted seem willing to admit, and we are amply justified in coming to this conclusion by several substantial reasons. Professor Tucker, who estimates the number of immigrants between 1790 and 1820 at 234,000, “calculated after a very laborious analysis the number of foreigners and their descendants to be above 1,000,000 in 1840.” Now, according to his own tables, the total number of immigrants who came here between 1790 and 1840 amounted to 949,346, and yet of all these people—over seventy-five per cent. of whom were adults—and their descendants, he would have us believe that there could only be found alive in 1840 the number just given. The total population had increased, within the period named, from 3,929,827 to 17,069,453—more than four hundred per cent.—while the descendants of the immigrants increased, according to him, only five per cent.
