Manners and Customs of the Welsh. From Bingley's Tour Round North Wales.
... They [the Welsh people] are much inclined to superstition. But in all countries, there are weak and foolish people; in England, many of our peasantry are ready to swallow, with the most credulous avidity, any ridiculous stories of ghosts, hobgoblins, or fairies. In Wales it is more general, and the people are certainly more credulous than the generality of the English. - There are very few of the mountaineers, who have not by heart a whole string of legendary tales of those disembodied beings.
The Roman Cavern, in Llanymynech-hill, called Ogo, has been long noted, as the residence of a clan of the fairy tribe, of whom the villagers relate many surprising and mischievous tricks. They have listened at the mouth of the cave, and have sometimes even heard them in conversation, but always in such low whispers, that their words have been never distinguishable. The stream that runs through it is celebrated as being the place in which they have been heard to wash their clothes and do several other kinds of work.
These busy little folk seem to be somewhat allied to what are called Knockers, which by the Welsh are believed to be a species of aerial beings, that are heard under-ground, in or near mines, who by their noises direct the miners where to find a rich vein. The following extraordinary account of them, is from a letter of Mr. Lewis Morris to his brother, Mr. W. Morris, Comptroller of the Customs at Holyhead, dated October 14th, 1754. I will make no comment upon it, and only preface it by observing, that Mr. Morris was a very learned and sensible man, and a person whose judgment is esteemed of great weight by every one who has been either acquainted with him or his writings.
"People who know very little of the arts or sciences, or the powers of nature, (which, in other words, are the powers of the author of nature) will laugh at us Cardiganshire miners, who maintain the existence of Knockers in mines, a kind of good-natured impalpable people, not to be seen, but heard, and who seem to us to work in the mines; that is to say, they are types, or forerunners of working in mines, as dreams are of some accidents which happen to us. The barometer falls before rain or storms. If we did not know the construction of it, we should call it a kind of dream, that foretells rain; but we know it is natural, and produced by natural means, comprehended by us. - Now how are we sure, or any body sure, but that our dreams are produced by the same natural means? - There is some faint resemblance of this in the sense of hearing: the bird is killed before we hear the report of the gun. However this is, I must speak well of these Knockers, for they have actually stood my very good friends, whether aerial beings, called spirits, or whether they are a people made of matter, not to be felt by our gross bodies, as air and fire, and the like.
"Before the discovery of Esgair y Mwyn mine, these little people, as we call them here, worked hard there day and night; and there are abundance of honest sober people, who have heard them, and some persons who have no notion of them or of mines either; but after the discovery of the great ore, they were heard no more.
"When I began to work at Llwyn Llw[y]d, they worked so fresh[?] there for a considerable time, that they even frightened some young workmen out of the work. This was when we were driving levels, and before we got any ore; but when we came to the ore, they then gave over, and I heard no more talk of them.
"Our old miners are no more concerned at hearing them blasting, boring holes, landing diads, &c. than if they were some of their own people; and a single miner will stay in the work, in the dead of night, without any man near him, and never think of any fear or harm they will do him; for they have a notion that the Knockers are of their own tribe and profession, and are a harmless people who mean well. Three or four miners together shall hear them sometimes, but if the miners stop to take notice of them, the Knockers will also stop; but let the miners go on at their own work, suppose it is boring, the Knockers will go on as brisk as can be, in landing, blasting, or breaking down the loose; and they were always heard, a little from them, before they came to the ore.
"These are odd assertions, but they are certainly facts, though we cannot, and do not pretend to account for them. We have now very good ore at Llwyn Llwd, where the Knockers were heard to work, but have now yielded up the place, and are no more heard. Let who will laugh, we have the greatest reason to rejoice and thank the Knockers, or rather God, who send us these notices."
An intelligent friend of mine informs me that those noises the Knockers, as they are called, have very lately been heard in the parish of Llanfihangel Ysceifrog, in Anglesea, where they continued at different intervals for some weeks. In accounting for these noises it has been observed, that they probably may have proceeded either from the echo of the miners at work, or from the dropping of the water; but these seem by no means sufficient, if Mr. Morris's assertion be true, that while the miners are going on with one kind of work, they are going on with another, while for instance, as he says, the miners are boring, they are blasting, the former certainly cannot be true, and the blasting entirely puts the latter conjecture out of the question, for droppings of water could never produce any effect of that kind. As I am only acquainted with the subject from report, I am under the necessity of leaving the elucidation of these extraordinary facts to some who have better opportunities of enquiring into them.
I have only to express a hope that the subject will not be neglected, and that those who reside in the neighbourhood where they are heard, will inquire into them carefully, and, if possible, give to the world a more accurate account of them than the present.
