As the Swat valley, and neighbourhood, which constitute the principal portion of the old province of Udyāna, have hitherto been inaccessible for archæological research, the following rough notes (made during the little time at my disposal as Chief Political Officer with the Chitral Relief Force, and lately as Political Officer for Dir and Swat) may induce others better qualified to devote some attention to this interesting neighbourhood. They are principally connected with the travels of the Chinese pilgrim Huan Tsiang, as given in Beal's “Buddhist Records of the Western World.”
