Mr. Sadler acknowledges that Cobbett exaggerates the number of emigrants when he states it at 150,000 a year. Yet even this estimate, absurdly great as it is, would not be sufficient to explain the increase of the population of the United States on Mr. Sadler’s principles. He is, he tells us, “convinced that doubling in 35 years is a far more rapid duplication than ever has taken place in that country from procreation only.” An increase of 20 per cent, in ten years, by procreation, would therefore be the very utmost that he would allow to be possible. We have already shown, by reference to the census of the slave population, that this doctrine is quite absurd. And, if we suppose it to { 249}be sound, we shall be driven to the conclusion that above eight hundred thousand people emigrated from Europe to the United States in a space of little more than five years. The whole increase of the white population from 1810 to 1820 was within a few hundreds of 2,000,000. If we are to attribute to procreation only 20 per cent, on the number returned by the census of 1810, we shall have about 830,000 persons to account for in some other way;--and to suppose that the emigrants who went to America between the peace of 1815 and the census of 1820, with the children who were born to them there, would make up that number, would be the height of absurdity.
We could say much more; but we think it quite unnecessary at present. We have shown that Mr. Sadler is careless in the collection of facts,--that he is incapable of reasoning on facts when he has collected them,--that he does not understand the simplest terms of science,--that he has enounced a proposition of which he does not know the meaning,--that the proposition which he means to enounce, and which he tries to prove, leads directly to all those consequences which he represents as impious and immoral,--and that, from the very documents to which he has himself appealed, it may be demonstrated that his theory is false. We may, perhaps, resume the subject when his next volume appears. Meanwhile, we hope that he will delay its publication until he has learned a little arithmetic, and unlearned a great deal of eloquence.
This { 250}is an eminently beautiful and splendid edition of a book which well deserves all that the printer and the engraver can do for it. The Life of Bunyan is, of course, not a performance which can add much to the literary reputation of such a writer as Mr. Southey. But it is written in excellent English, and, for the most part, in an excellent spirit. Mr. Southey propounds, we need not say, many opinions from which we altogether dissent; and his attempts to excuse the odious persecution to which Bunyan was subjected have sometimes moved our indignation. But we will avoid this topic. We are at present much more inclined to join in paying homage to the genius of a great man than to engage in a controversy concerning church-government and toleration.
