which formerly overwhelmed, with their armies, the Roman empire? The question supposes, what I believe is not true, that they had once more inhabitants than they could maintain, and overflowed only because they were full.
This is to estimate the manners of all countries and ages by our own. Migration, while the state of life was unsettled, and there was little communication of intelligence between distant places, was, among the wilder nations of Europe, capricious and casual. An adventurous projector heard of a fertile coast unoccupied, and led out a colony; a chief of renown for bravery, called the young men together, and led them out to try what fortune would present. When Cæsar was in Gaul, he found the Helvetians preparing to go they knew not whither, and put a stop to their motions. They settled again in their own country, where they were so far from wanting room, that they had accumulated three years' provision for their march.
The religion of the north was military; if they could not find enemies, it was their duty to make them: they travelled in quest of danger, and willingly took the chance of empire or death. If their troops were numerous, the countries from which they were collected are of vast extent, and, without much exuberance of people, great armies may be raised where every man is a soldier. But their true numbers were never known. Those who were conquered by them, are their historians, and shame may have excited them to say, that they were overwhelmed with multitudes.

I have heard from an English officer, not much inclined to favour them, that their behaviour deserved a very high degree of military praise; but their number has been much exaggerated. One of the ministers told me, that seventy thousand men could not have been
