MAC-FIR AROIS.
The heir of Aros, a young man of great personal activity, and, it is said, of dissolute manners, having anopinion of himself that there was no horse he could not ride, was taken by a Water-horse into Loch Frisa, a small lake about a mile in length in the north-west of Mull and devoured. This occurred between his espousal and marriage, and the Lament composed by his intended bride is still and deservedly a popular song in Mull. There seems to be this much truth in the story, that the young man was dragged into Loch Frisa by a mare which he was attempting to subdue and drowned. It would appear from the song that his body was recovered. The popular details of the incident vary considerably, and are of interest as illustrative of the growth of tales of superstition.
One account has it that a remarkably handsome grey mare came among horses belonging to the tenant of Aros pasturing on the rushes at the end of Loch Frisa. One day his son haltered and mounted it. The grey stood quite quietly till it got the young man on its back. It then rushed into the loch.
Another account says the young man found a mare in the hills, which he took to be one of those belonging to his father. He caught it with the intention of riding home, but the mare took out to Loch Frisa, and he was there devoured by Water-horses.
A third account says the Water-horse was kept all winter, with the cow-shackle about its neck, and remained so quiet and steady, that at last the shackle was neglected. The son of the tenant rode it one dayto the peat-moss, three other horses following behind in usual form, when it suddenly rushed away to the lake, and nothing was ever seen of the youth or the horses but the livers.
A fourth account says, in spring a band of men went to the hill to catch a young horse wanted for harrowing or to send to market. They were unable to catch it, and next day Aros’s son himself went with them. He caught what he supposed to be the horse wanted and jumped on its back. The horse rushed at full speed towards the loch, and the young man found he could not throw himself off. The horse’s liver came ashore next day, the animal, it is supposed, having been killed by the other Water-horses tenanting the lake, when they felt the smell of a man off it.
There is still another account, that Mac-fir Arois was twice taken away by the Water-horse. The first time, he managed to put a foot on each side of a gate, in passing through, and allowed the horse to pass on. The second time, a cap which hitherto had kept the horse, was forgotten. In the terrible career of the steed to the loch, the young man clasped his arms round its neck, and could not unclasp them. His lungs came ashore next day.
