Pwca, or Pooka, is but another name for the Ellylldan, as our Puck is another name for the Will-o'-wisp; but in both cases the shorter term has a more poetic flavour and a wider latitude. The name Puck was originally applied to the whole race of English fairies, and there still be few of the realm who enjoy a wider popularity than Puck, in spite of his mischievous attributes. Part of this popularity is due to the poets, especially to Shakspeare. I have alluded to the bard's accurate knowledge of Welsh folk-lore; the subject is really one of unique interest, in view of the inaccuracy charged upon him as to the English fairyland. There is a Welsh tradition to the effect that Shakspeare received his knowledge of the Cambrian fairies from his friend Richard Price, son of Sir John Price, of the priory of Brecon. It is even claimed that Cwm Pwca, or Puck Valley, a part of the romantic glen of the Clydach, in Breconshire, is the original scene of the 'Midsummer Night's Dream'--a fancy as light and airy as Puck himself.[16] Anyhow, there Cwm Pwca is, and in the sylvan days, before Frere and Powell's ironworks were set up there, it is said to have been as full of goblins as a Methodist's head is of piety. And there are in Wales other places bearing like names, where Pwca's pranks are well remembered by old inhabitants. The range given to the popular fancy in Wales is expressed with fidelity by Shakspeare's words in the mouth of Puck:
