A vast number of places out of the Highlands still retain their Gaelic names, and it is interesting to understand them; for example, TINTOCK is the highest mountain in Lanarkshire; and the name has a meaning in Gaelic, “The house of the mist” (Tigh n’ to-ag); and a local rhyme shews that to be the true meaning of the name, which has no English meaning.
On Tintock tap there is a mist,
And in the mist there is a kist,
And in the kist there is a cup,
And in the cup there is a drap;
Tak up the cup and drink the drap,
And set the cup on Tintock tap.There was a popular tale about this mountain which I failed to get; but a cup, with some mysterious drink, is common in Celtic traditions.
