There are many routes from the plain into the hills of Palpa; but, except by a few smugglers, most of these have been deserted since the conquest, for which there seem to be two reasons. The Nepalese are desirous of having only a few open routes, by which an army from the low country might penetrate into the hills, and they think that in a few years the neglected routes will be either altogether forgotten, or be so overgrown with woods as to prevent access. The few remaining roads will then be easily guarded by a small force. But besides the military point of view, they are desirous of having few passages as a point of economy in collecting the customs. Accordingly, so far as they can, they have stopt every pass, except that by Butaul, which, of course, has become a considerable mart, although most inconveniently situated. It stands on the plain, but in a recess of the mountains, and is so dreadfully unhealthy, that no one resides there in the rainy season. The Rajas had a house called Nayakot on a hill overhanging the town, or assemblage of huts; but I am told, that this castle is not sufficiently elevated to be exempt from the effects of the insalubrious air. The Palpa Rajas possessed also a very important mart in the hills. It is called Rerighat, and is situated on the bank of the Narayani. The best, or rather the only tolerable roads passing through the country either from the east and west, or from the north and south, pass this route; and it seems to be of equal importance either in a military or commercial view. During the cold season there is at Rerighat a fair (Mela) which lasts for three or four months, and is frequented by a great number of traders from all parts of the mountains. The road from Butaul to Rerighat by Morihang, Mosihang, and Tansen, was said to be far from difficult; but what idea a mountaineer annexed to a difficult road is not easy to determine. Some of them say, that loaded oxen could pass; others say that they could not. It is generally admitted, that the easiest route from Rerighat to the plains would be east through Tansen, Rampur, Nayakot, and Dewghat, but this road is at present stopt.
