It has just been said that those who were in the advance in this great emigration were pushed on by those who followed. Who were the advance of this westward movement, the first Aryans who entered Europe? There is no reasonable doubt that they were the Celts, the people who, some thirteen hundred years ago, were in absolute and complete possession of the islands of Great Britain and Ireland, and a small part of the northwestern coast of what is now, but was not then, France. These people, this head of the Aryan column, passed through southern Europe, (we know it by the names they left behind them, given to places during their temporary, but not short occupation of the soil,) and coming to the ocean, went northward, then crossed the English channel, and took possession of Britain and Ireland. There they stopped simply because they could go no farther. But they were still pushed by those who followed. The invasion of Britain by the Romans, and yet more, the after invasion and occupation of it by the so-called Anglo-Saxons, our forefathers, were a _mere continuation of the Aryan emigration_ which had begun at the foot of the Hindoo Kosh, in Asia, thousands of years before. These Celts who went first were followed by the people who, in close connection with them as to time and affiliation of blood, became the Latin races (old Romans, Italians, Spaniards, French), and the Greeks. It was natural that the first stream of Aryan emigration into Europe should take its course through the countries of these peoples, because they lie at the south, on the borders of the Mediterranean Sea. Men never go northward to find homes amid snows and ice one half the year, if they can find land of more genial clime unoccupied or occupyable. The leading bodies of the Celts having reached the ocean in the southern part of Europe, and being pushed on by the steady flow from behind, moved northward, and as we have already seen, at last left the continent, and rested in Britain and Ireland. Here, from their insular position, they were able to maintain their footing firmly, if not undisturbed, for many centuries. They were not displaced in Britain until about thirteen centuries ago; and then they were not driven onward, as before they had been driven; for there was no place whither to drive them. They were, in the words of an old adage, perhaps as old as this very time, “between the devil and the deep sea;” and most of them were slain to make room for their fellow Aryans, their far-away kindred, whom they knew not, and had no reason to know, and whom they hated with good reason.
