It appears evident to me, that Colonel Kirkpatrick {206} judged rightly in supposing that this valley has formerly been a lake, which has gradually deposited all the alluvial matter that now forms the different substrata of the plain. The extent of the lake may in all places be traced by that of the alluvial matters, above the edges of which generally appear irregularly shaped large stones, which, having rolled down from the hills, stopped at the water’s edge as usual in the lakes of hilly countries. The memory of the lake is preserved in the fables contained in the books of the natives, which mention the deity by whom the mountain was cleft to drain off the water, together with numerous circumstances connected with this event. The following is an account of these fables that was communicated to me by Colonel Crawford. When the valley of Nepal was an immense lake, an incarnation of Buddha was born in that country. A petition was therefore made to the gods requesting that the lake might be drained, that the valley might be filled with inhabitants, and that thus the number of the followers of Buddha might increase. The gods attended to this petition, and ordered Menjoo Dev’ to evacuate the waters by making a cut through the mountains. This he performed with one blow of his scimitar, and ever since, the waters of the Vagmati have flowed through the gap, which he then formed. The spirit who had presided over the lake was a large serpent, who, finding his water become scanty, and the dry land beginning every where to appear, became exceedingly wroth, but he was pacified by the gods, who formed for his residence a miraculous tank, which is situated a little to the southward of Lalita Patan. This tank has a number of angles, all of which cannot be seen at once from any station; they can only, therefore, be numbered by walking round the tank; the miraculous nature of which, in the opinion of the natives, is fully demonstrated by no two persons who make the attempt to number these angles, being able to agree concerning this important point. The Brahmans, it must be observed, have invented another story, equally extravagant, and attribute the blow which cleared the valley to Anirudha, the grandson of Krishna, who at the same time killed Sangkhasur, who until then had been lord of Nepal.
