Thus the Kimri, or as we may now call them the Cymry, did not enter England until about 300 /B.C./, and for a time seem to have limited their settlements to the chalk lands. By degrees they spread to the oolite ridge, but it is doubtful whether they had progressed farther when Cæsar landed here. The dense Midland forest kept them back, and they seem to have made no attempt to reach Ireland, or, until after Cæsar’s time, to dispossess the Gaels of the Parret marshes. But early in the Christian era civil wars occurred between the tribes on either side of the Thames, which led eventually to Roman interference, and it was during the campaign of Aulus Plautius and his successors that dispossessed Cymric leaders, like Caractacus, fled with their followers to the west, and introduced into Wales a Cymric or Brythonic speech, the first Wiro dialect to be spoken regularly in the principality, except along trade routes and in the small Gaelic settlements above Cardiff. /Chapter XV/ CONCLUSION We have now traced in outline the history of Celtic peoples and Celtic lands from the Wurmian glaciation to the Roman conquest of Britain, and have cited as evidence the conclusions drawn from linguistic science and an extensive array of data of an anthropological and archæological character. Though most of the main conclusions arrived at have been suggested before, many of them to be subsequently discarded as lacking sufficient evidence, the main story of the Wiros and their wanderings, as I have outlined it above, seems to be compatible with all the positive information we possess, though it is in conflict, as I am well aware, with many theories that have been built upon them. My views will not, I feel sure, meet with ready acquiescence from some Celtic scholars, especially from those who follow Zimmer and Kuno Meyer. This school has for thirty years been engaged in proving that there is no philological evidence for the existence of Goidelic speech in England or Wales, except such as was introduced from Ireland in the third or fourth century, /A.D./ I do not wish to dispute the philological evidence, nor do I feel competent to do so. I am ready to admit, at any rate for the sake of argument, that no such philological evidence exists. But England has been overrun by Kimri, Romans and Saxons, since the Gaels are believed to have come, and the absence of such evidence is not surprising.
