Thus far the southern extension of this, our second Irish race; we may look for a moment at its distribution in the north. Across the shallow sea which separates us from Britain we find the same race, clinging always to the Atlantic seaboard. It dominates south Wales, where its presence was remarked and commented on by the invading Romans. It is present elsewhere through the Welsh mountains, and much more sparsely over the east of England; but we have ample evidence that at one time this tall, dark race held the whole of England in undisputed possession, except, perhaps, for a remnant of the Hyperborean dwarfs. In the west of Scotland, and especially in the Western Isles, it is once more numerous; and we find offshoots of the same race in the dark-haired Norwegians,--still holding to the seaboard of the Atlantic.

Such is the distribution of this once dominant but now dwindled race, which has gradually descended from the summit of power as ancient Rome descended, as Greece descended, or Assyria or Egypt. But we can look back with certainty to a time when this race, and this race only, held complete possession of all the lands we have mentioned, in north or south, in Europe or northern Africa; holding everywhere to the Atlantic coast, or, as in the Mediterranean isles, evidently pressing inward from the Atlantic, past the Pillars of Hercules, through the Strait of Gibraltar.

It is evident at once that the territory of this race corresponds exactly, throughout many countries, with the territory of the cromlechs and standing stones; where we find the one, as in Ireland, Brittany, Spain, we find the other; where the one is absent, as in Germany, or northern Italy or Greece, the other is likewise absent. The identity is complete. We are justified, therefore, in giving the same provisional name to both, and calling them Atlantean, from their evident origin not far from Atlas, and their everywhere clinging to the Atlantic coast. We can find traces of no other race which at all closely fulfills the necessary conditions of uniform and undisputed extension, through a long epoch, over the whole cromlech region--the only conditions under which we can conceive of the erection of these gigantic monuments, or of the long established and universally extended spiritual conditions which make possible such vast ideal enterprises.

In this race, therefore, which we have called Atlantean, we find the conditions fulfilled; of this race, and of no other, we still find a lingering remnant in each of the cromlech countries; and we hardly find a trace of this race, either now or in the past, in the lands which have no cromlechs or standing stones.

We have already seen that the standing stones of Cavancarragh, four miles from Fermanagh, were, within the memory of men still living or of their fathers, buried under ten or twelve feet of peat, which had evidently formed there after their erection. We have here a natural chronometer; for we know the rate at which peat forms, and we can, therefore, assign a certain age to a given depth. We have given one mode of reckoning already; we find it corroborated by another. In the Somme valley, in northern France, we have a Nature's timepiece; in the peat, at different levels, are relics of the Roman age; of the Gaulish age which preceded it; and, far deeper, of pre-historic races, like our Atlanteans, who preceded the Gauls. The date of the Roman remains we know accurately; and from this standard we find that the peat grows regularly some three centimeters a century, or a foot in a thousand years.

On the mountain side, as at Cavancarragh, the growth is likely to be slower than in a river valley; yet we may take the same rate, a foot a thousand years, and we shall have, for this great stone circle, an antiquity of ten or twelve thousand years at least. This assumes that the peat began to form as soon as the monument was completed; but the contrary may be the case; centuries may have intervened.

We may, however, take this as a provisional date, and say that our cromlech epoch, the epoch of the Atlantean builders, from Algeria to Ireland, from Ireland to the Baltic, is ten or twelve thousand years ago; extending, perhaps, much further back in the past, and in certain regions coming much further down towards the present, but having a period of twelve thousand years ago as its central date. It happens that we have traditions of a great dispersion from the very centre we have been led to fix, the neighborhood of Atlas or Gibraltar, and that to this dispersion tradition has given a date over eleven thousand years ago; but to this side of the subject we cannot more fully allude; it would take us too far afield.

We have gone far enough to make it tolerably certain, first, that these great and wonderful monuments were built when uniform conditions of order, uniform religious beliefs and aspirations, and a uniform mastery over natural forces extended throughout a vast region spreading northward and eastward from Mount Atlas or Gibraltar; we have seen, next, that these conditions were furnished when a well-defined race, whom we have called Atlantean, was spread as the dominant element over this whole region; and, finally, we have seen reason to fix on a period some eleven or twelve thousand years ago as the central period of that domination, though it may have begun, and probably did begin, many centuries earlier. The distribution of the cromlechs is certain; the distribution of the race is certain; the age of one characteristic group of the monuments is certain. Further than this we need not go.

When we try to form a clearer image of the life of this tall archaic race of cromlech-builders, we can divine very much to fill the picture. We note, to begin with, that not only do they always hold to the Atlantic ocean as something kindred and familiar, but that they are found everywhere in islands at such distances from the nearest coasts as would demand a certain seamanship for their arrival. This is true of their presence in Malta, Minorca, Sardinia; it is even more true of Ireland, the Western Isles of Scotland, the Norwegian Isles; all of which are surrounded by stormy and treacherous seas, where wrecks are very common even in our day. We must believe that our tail, dark invaders were a race of seamen, thoroughly skilled in the dangerous navigation of these dark seas; Caesar marveled at, and imitated, the ship-building of the natives of Brittany in his day; we equally admire the prowess of their sons, the Breton fishermen, in our own times. We find, too, that in the western districts and ocean islands of our own Ireland the tall, dark race often follows the sea, showing the same hereditary skill and daring; a skill which certainly marked the first invaders of that race, or they would never have reached our island at all. We are the more justified in seeing, in these dark cromlech-builders, the Fomorians of old Gaelic tradition, who came up out of the sea and subjugated the Firbolgs.
