Thankot is a small town, finely supplied with wood and water. It stands on a rocky eminence at the south west corner of the valley of Nepal, in a district separated from the
other parts of the plain by a low ridge of hills. On the most conspicuous part of this ridge stands Kirtipur, a considerable town. This part of the valley seems to be a good deal elevated above the portion which contains Kathmandu; and I found the heat of a spring in a small wood above Thankot to be 59½ degrees of Fahrenheit’s thermometer. From Thankot to Kathmandu is about seven miles over very uneven cultivated fields, with no roads but foot-paths.
The larger valley of Nepal is somewhat of a circular form, and is watered by numerous branches of the Vagmati, which flow from the surrounding hills towards the centre, and unite into one stream a little way south from the capital. From the place of junction the Vagmati runs south, and goes to the Tariyani, after having forced a passage through the mountains. Taken in the largest sense, therefore, the valley of Nepal comprehends all the grounds watered by these branches of the Vagmati, and, according to this definition, it is about twenty-two miles from east to west, and twenty miles from north to south. This extent is every where bounded by a chain of hills, all of which are steep, and some of them rise into high mountains. Of these the most remarkable are Shiva, or Siwapuri, on the north, Nagarjun on the west, Chandangiri on the south-west, Pulihu on the south east, and Devikot on the east. It must be observed, that from these hills, various branches reach a considerable way into the plain, and separate from it small vallies, most of which are considerably elevated above the general level, and from these vallies issue the various streams by which the country is irrigated. The larger valley, reduced by these branches, may be about fourteen miles each way. A person placed in the centre of this extent would consider the whole as one great level, but on travelling about, he frequently comes to very deep hollows,
excavated by the various branches of the river, which flow with a very gentle current in large sandy channels. Except after heavy rains, these are almost always fordable, and are commonly sunk fifty or sixty feet perpendicular below the general level of the plain.
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.
The Vagmati must always have flowed from the valley, to carry away the vast body of water collected in the rainy season, and which evidently was confined by a narrow ledge of rocks, which crosses the channel of the river, where it enters the southern mountainous district. At that time the bottom of the lake must have been a smooth cavity, and it must have been surrounded by small narrow glens, pouring their streams into the lake, as they now do into the valley. As the river gradually wore away the rock, over which it must have been precipitated in a cataract, the water in the lake would subside, and the various streams running from the glens would form deep excavations in the soft matter that had formerly been deposited by the water; and this operation would go on, till the ledge of rock was entirely worn away, and a stop was put to the sinking of the river, by the immerse mass of rock opposed to its influence.
While the lake existed, there must have appeared in it two
islands, which now form hills. The one is called Sambhunath, or rather Swayambhunath, as being, in the opinion of the Bouddhists of Nepal and Thibet, a favourite residence of the Supreme Being. It is an elegant hill, with two peaks occupied by religious buildings, and covered with the most stately trees. It is a conspicuous object from almost every part of the valley, and every where appears to great advantage.
