A holograph manuscript of poems by Iorwerth Cyfeiliog Peate, described by the author, in a letter [to the Librarian of the National Library of Wales ], 26 June [19]39, accompanying the manuscript, as the printers' copy of his volume of verse, Plu'r Gweunydd. [Cerddi a Sonedau (Lerpwl, 1933)]. Three points of difference, however, can be noted between the text of the present manuscript and the published work - (a) the difference in the order of the poems, which, in the printed volume, have been grouped under subject headings, this not being the case in the manuscript (the author, in the above mentioned letter, mentions this difference, and also answers the charge made by one critic, that, in grouping the poems thus, he had copied the example of 'Eifion Wyn' [Eliseus Williams], by stating that the arrangement under subject headings was not his idea, but had been done at the request of the publishers), (b) the printed volume contains four poems, 'Pentre'r Celyn' (p. 17), 'I Glychau'r Goets Fawr' (p. 38), 'Y Galw' (pp. 43-4), and 'Yn Dawel, Bêr Ddyfi' (p. 61), which do not appear in the manuscript, and (c) minor textual variations, e.g., A'th unllef oriog / O' th unllef oriog ('Maldwyn', line 1), Ofer it ddisgwyl wrth Dduw Dad / ar Dduw Dad ('Adar To yn Chwefror', last line), and Yfory mi rannaf yr holl fyd / i'r holl fyd ('Cyfoeth', line 1).
