chest and drooping shoulders, utterly unlike the muscular and vigorous Gaelic women who were true consorts to their men when they came over to conquer the island of Britain. After a lapse of time the long-head began to reassert itself, and the infusion of its blood into the veins of the dominant race led to great modification of its harshness of feature. When iron was introduced into Britain, whether by peaceable means or whether by the second Aryan invasion, that of the Cymri or Britons, we do not know, but when Cæsar landed in Britain, B.C. 55, he found that iron was in general use. The second Aryan invasion alluded to was that of the true Britons. They also came from the Alps, where they had lived on platforms constructed on the lakes. They occupied the whole of Britain proper, but not Scotland, and made but attempts to effect a landing in Ireland. They were entirely out of sympathy with the original race and its ideas, and did not assimilate their religion and adopt their practices as had the Gaels. The distinction between the two branches of the great Celtic family is mainly linguistic. Where the British employed the letter _p_, the Gael used the hard _c_, pronounced like _k_. For instance, _Pen_, a head, in British, is _Cen_ in Gaelic; and we can roughly tell where the population was British by noticing the place names, such as those beginning with Pen. When these were Gaels, the same headlands would begin with Cen. "By Tre, Pol, and Pen You know the names of Cornishmen," and this at once decides that the inhabitants of the western peninsula were not Gaels. From the lakes of Switzerland the Britons had brought with them their great aptitude for wattle-work. They built their houses and halls, not of stone, but of woven withies. Cæsar says that they were wont to erect enormous basket-work figures, fill them with human victims, and burn the whole as sacrifices to their gods. It is a curious coincidence that on some of the old Celtic crosses are found carved imitations of men made of wicker-work. These represent saints made of the same material and in the same manner by the same people, after they had embraced Christianity and abandoned human sacrifices.[6] Let us try to imagine what was the mode of life of those people who raised their monuments on Dartmoor. They were pastoral, but they also certainly had some knowledge of tillage. In certain lights, hillsides on the moor show indications of having been cultivated in ridges, and this not with the plough, but with the spade. We cannot say that these belong to the early population, but as they are found near their settlements it is possible that they may be traces of original cultivation. But we know from the remains of grain found in the habitations and tombs of the same people in limestone districts that they were acquainted with cereals, and their grindstones have been found on Dartmoor in their huts.
