"Dr Seybert says, that the passengers to ten of the principal ports of the United States, in the year 1817, amounted to 22,235; of whom 11,977 were from Great Britain and Ireland; 4164 from Germany and Holland; 1245 from France; 58 from Italy, 2901 from the British possessions in North America; 1569 from the West Indies; and from all other countries, 321. These, however, we may conclude, with the editor of Styles's Register, were far short of the number that arrived." We have not the honour of knowing either Dr Seybert or the editor of Styles's Register. We cannot, therefore, decide on their respective claims to our confidence so peremptorily as Mr Sadler thinks fit to do. Nor can we agree to what Mr Sadler very gravely assigns as a reason for disbelieving Dr Seyberts's testimony. "Such accounts," he says, "if not wilfully exaggerated, must always fall short of the truth." It would be a curious question of casuistry to determine what a man ought to do in a case in which he cannot tell the truth except by being guilty of wilful exaggeration. We will, however, suppose, with Mr Sadler, that Dr Seybert, finding himself compelled to choose between two sins, preferred telling a falsehood to exaggerating; and that he has consequently underrated the number of emigrants. We will take it at double of the Doctor's estimate, and suppose that, in 1817, 45,000 Europeans crossed to the United States. Now, it must be remembered that the year 1817 was a year of the severest and most general distress all over Europe,--a year of scarcity everywhere, and of cruel famine in some places. There can, therefore, be no doubt that the emigration of 1817 was very far above the average, probably more than three times that of an ordinary year. Till the year 1815, the war rendered it almost impossible to emigrate to the United States either from England or from the Continent. If we suppose the average emigration of the remaining years to have been 16,000, we shall probably not be much mistaken. In 1818 and 1819, the number was certainly much beyond that average; in 1815 and 1816, probably much below it. But, even if we were to suppose that, in every year from the peace to 1820, the number of emigrants had been as high as we have supposed it to be in 1817, the increase by procreation among the white inhabitants of the United States would still appear to be about 30 per cent. in ten years.
