It has been said that almost everything connected with Irish history and topography is peculiar. The truth of this can hardly be doubted. If the ancient Irish were a non-Aryan race, the strange phases of their history and the abundance of Irish place names might not strike us as so curious. But it is well known that the Irish are Aryans, and that they are substantially the same people as the ancient Britons were; yet nothing in the history of England or of Great Britain will satisfactorily account for the fewness of place names in the latter country as compared with Ireland. British, but especially English, place names are, in a vast majority of cases, either of Saxon, Norse, or Celtic origin. Their fewness as compared with Irish place names is what strikes a native of Ireland with astonishment. There are probably as many place names in a single Irish province as there are in the whole of England. The townland nomenclature of Ireland is almost unknown in England. The names of all the townlands in Ireland can be seen in the Government Survey of 1871. They number, exclusive of the names of cities, towns, and villages, about 37,000. But it is only the place names that mean human habitations, places erected by men, and where men dwelt, that shall be mentioned here. Let five denominations of place names suffice to show their immensity--namely, _ballys_, _kills_, _raths_, _duns_ and _lises_. The first means towns or steads; the second, churches or cells; and the three last mean fortified habitations of some kind. Of _ballys_ there are 6700, of _kills_ 3420, of _lises_ 1420, of _raths_ 1300, and of _duns_ 760, making altogether 13,600 place names meaning habitations of some kind. But this is not the half of them! The place names in the subdivisions of townlands are not mentioned at all. There is a parish in Westmeath in which there are three place names beginning with _rath_, and three with _kill_, none of which is mentioned in the printed list of townlands. Multitudes of names in which some one of the five words mentioned is included have been translated or changed; just as Ballyboher has been made Booterstown, and Dunleary made Kingstown. Many place names in which _bally_, _kill_, _dun_, _rath_, and _liss_ occur are not included in the numbers given, for very often the adjective goes before the noun, as in such names as Shanbally, Shankill, Shanlis, Shandun, &c. Taking everything into consideration, it would seem fair to estimate that not more than half the place names formed from the five words that have been mentioned appear in the printed list of Irish townlands; then we have the astounding total of over _twenty-seven thousand_ place names in Ireland formed from five words that mean human habitations.
