Ku-lu-to (I, 298) evidently is identified rightly with Kulu, N. N. W. of Simla, in the basin of the upper waters of the Biās, which must be the ‘great river’ crossed by the pilgrim when he turned south. Mr. Watters admits that the designation, She-lō-t‘u-lu, of the country next visited may represent Śatadru. The region so named, which was bounded on the west by a ‘large river’, the Sutlaj or Śatadru, may be taken as comprising the western portion of the Ambāla (Umballa) District, as well as the Sahrind (Sarhind), and Ludīāna Districts, with the Patiāla State, or part of it.
