being commissioned, he was appointed an officer under the Army Education Scheme, a post for which he was well fitted by his training and experience and which he occupied until he was appointed in 191 9 to the staff of the National Library of Wales, as Assistant Librarian under the late Sir John Ballinger. From that time on he was inseparably associated with the National Library, becoming its Head on the retirement of Sir John Ballinger in 1930. The position to which he then succeeded provided him with ample opportunity for displaying those qualities of mind and character which enabled him greatly to extend the scope of the Library's act- ivities and ensured for him the confidence of those whom he served no less than of those who served him. Building upon foundations already laid by his predecessor, it is to the manner in which he interpreted its functions and his own duties as the custodian of its treasures that the place occupied today by the National Library in the mind of the people of Wales is so largely due. The additions made to the instit- ution in his time and the vast field of activities it now covers are a tribute to his vision no less than to his devotion to the cause he served. His services were recognised in various ways. He received the honour of knighthood and the University conferred upon him its highest honorary distinction. His appointment as High Sheriff of the county of Merioneth was a fitting tribute to the personal position that he occupied. He took up his official duties with customary readiness, though he had other heavy burdens to bear, and began with character- istic zeal a year of office which, to the deep regret of all, he was not destined to complete. He was an active and highly valued member of the Cardiganshire Antiquarian Society and until recently, when pressure of other work compelled him to curtail his activities, he was the editor of its journal, Ceredigion, which in form and content bore witness to the high standard with which all that came through his hands had to comply. His service to this Society, when the other calls on his time were so numer- ous and so varied, is an example of the ever-ready support he gave to every movement which had for its object the deepening of interest in the history and culture of Wales. Among those who in the years to come will be remembered with gratitude and appreciation for having served their generation with unvaried devotion who, when in full vigour of body and mind, had planned and carried out great schemes with acknowledged efficiency and who, when vigour had given place to languor, had not faltered- among those the name of William Llewelyn Davies will stand high.
