Letter [1910] from T. C. Evans ('Cadrawd') to T. H. Thomas ('Arlunydd Penygarn') discussing among other things his recently published volume HEN GWNDIDAU ... - 'it is very fortunate that we (his co-author L. J. Hopkin-James and himself) have been able to collect such gems which the world [k]new of them not, and by Bards of Tir Iarll exclusively. The Book will be precious when it will be really known. Few who have subscribed for it realized that they were in for such value'.
