Many of the souterrains in this part of the world are now blocked up, and of some the entrance is no longer known, although they have been explored within living memory; others have been destroyed. There was a souterrain a short distance from Ballycairn fort in a field opposite to Cranogh National School. The master of this school told me that fifteen or sixteen years ago these underground buildings existed, but now they have been all quarried away. He also mentioned a tradition that there was a subterranean passage under the Bann.
On the opposite bank of the river, near Portstewart, I heard of several of these underground dwellings.
One was on the land of an old farmer eighty-four years of age. He told me he had been in this cave, but no one could get in now. It had been hollowed out by man, but the walls were not built of stones. There were several rooms; you dropped from one to another through a narrow hole. The rooms were large, but low in the roof; in one of them a quantity of limpet-shells were found. He added that some said that the Danes had built these caves, others that the clans made them as places of refuge. He added that the Danes of those days had sandy hair and were short people; not like the sturdy Danes of the present day. These are well known to the seafaring population of Ulster, and we sometimes find the old Danes spoken of as a tall, fair race; probably this is a true description of the medieval sea-rovers. The short Danes I should be inclined to identify with the Tuatha de Danann, and I believe that, notwithstanding the magical portents which abound in the tales that have come down to us, we have here a very early people who had made some progress in the arts.
This double use of the name Dane seems at times to have perplexed the older writers. The Rev. William Hamilton, in his "Letters on the North-East Coast of Antrim," published towards the end of the eighteenth century, gives a description of the coal-mines of Ballycastle[33] and of the very ancient galleries, with the pillars, left by the prehistoric miners, supporting the roof, which had been discovered some twelve years before he wrote. He tells us that the people of the place ascribed them to the Danes, but argues that these were never peaceable possessors of Ireland, and that it is not "to the tumultuary and barbarous armies of the ninth and tenth centuries ... we are to attribute the slow and toilsome operations of peace." He mentions how the stalactite pillars found in these galleries marked their antiquity, and ascribes them to some period prior to the eighth century, "when Ireland enjoyed a considerable share of civilization."
In the same way John Windele, writing in the Ulster Journal of Archæology for 1862, speaks of the mines in Waterford having been worked by the ancient inhabitants, and adds: "One almost insulated promontory is perforated like a rabbit-burrow, and is known as the 'Danes' Island,' the peasantry attributing these ancient mines, like all other relics of remote civilisation, to the Danes."[34]
From my own experience I can corroborate this statement. An artificial island in Lough Sessiagh, in Co. Donegal, was shown to me as the work of the Danes. The forts on Horn Head and at Glenties are also ascribed to them.
The use of the souterrains was not confined to prehistoric times. The one at Greenmount appears to have been inhabited by the medieval Danes, as a Runic inscription, engraved on a plate of bronze, has been discovered in it, the only one as yet found in Ireland. In 1317 every man dwelling in an ooan, or caher's souterrain, was summoned to join the army of Domched O'Brian.[35] The French traveller, Jorevin de Rocheford, speaks of subterranean vaults where the peasants assembled to hear Mass,[36] and in still more recent times the smuggler and the distiller of illicit whisky found them convenient places of concealment.
In a former paper I referred to the lost secret of the heather beer, and the tragic ending of the last of the Danes.[37] As the story was told me near Ballycairn Fort, the father said: "Give my son the first lilt of the rope, and I will reveal our secret"; but when the son was dead the father cried: "Slay me also, for none shall ever know how the heather beer was brewed!"
In a paper read to this club Mr. McKean[38] mentioned that this story had been told to him in Kerry, where I, too, heard it. It appears to be almost universal in Ulster. When visiting Navan Fort, the ancient Emania, near Armagh, I was told that on this fort the Danes made heather beer. I asked if any heather grew in the neighbourhood, but the answer was, not now. There are variants of the tale. In some parts of Donegal it is wine, not beer, that the Danes are said to have made. As a rule the slaughter is taken for granted, and very little said about it; but a farmer in Co. Antrim gave me a full account of the massacre, how at a great feast a Roman Catholic sat beside each Dane, and at a given signal plunged his dirk into his neighbour's side, until only one man and his son remained alive; then followed the usual sequel.
These short Danes are said to have had large feet, and one man described their arms as so long that they could pick anything off the ground without stooping. Long arms are also a characteristic of the traditional dwarf of Japan, probably an ancestor of the Aino.[39] As I mentioned in a previous paper,[40] large feet are also a traditional characteristic of the Pechts, who are generally said to have been clad in skins or in grey clothes. They have occasionally superhuman attributes ascribed to them. The same man who spoke of the long arms of the Danes said the Pechts could creep through keyholes—they were like "speerits"—and he evidently regarded both them and the fairies as evil spirits. At the same time he said they would thresh corn or work for a man, but if they were given food, they would be offended, and go away.
