On arriving at what may be called the mountains, though they are not separated from the low hills by any distinct boundary, we have a very elevated region, consisting of one mountain heaped on another, and rising to a great height, so that, when any fall happens in winter, their tops are for a short time covered with snow. The inhabited vallies between these are in general very narrow, and are of very various degrees of elevation, probably from 3000 to 6000 feet of perpendicular height above the plains of Puraniya. Of course, they differ very much in their temperature; so that some of them abound in the ratan and bamboo, both of enormous dimension, while others produce only oaks and pines. Some ripen the pine-apple and sugar-cane, while others produce only barley, millet, and other grains. Some estimate of the climate of this region may be formed by means of the accompanying register of the weather kept near Kathmandu, although it is very imperfect, from that want of convenience which must attend travellers in so remote a country. The winter we passed in Nepal, was reckoned uncommonly mild; and in place of the rain, which we had at that season, in most years snow falls at Kathmandu. A more accurate estimate of the average heat of the valley may be obtained from that of its springs, which by repeated trials at a fine spring nearly on a level with Kathmandu, I found to be 64° of Fahrenheit’s thermometer; but in a spring near Thankot, the heat in April was 59½°; in one at Chitlong it was a degree lower; and at Bhimphedi, on the skirts of the lower hills, it was 63°. This cold, so uncommon in the latitude of between 27° 30′, and 26° 41′, must be attributed to the great elevation of the country, for the neighbourhood of the snowy peaks of Emodus could produce little effect, as the winds were very seldom from that quarter. We have no data upon which we can calculate the height of the valley of Nepal with any considerable accuracy. The nearest approach I can make to it, is by the difference of the average height of the barometer observed during the month of February 1802, in the Tariyani, and during the February following at Kathmandu. The average height at the former place was 29,60 inches, while at the latter it was 25,25 inches. The difference of the logarithms of these numbers, rejecting the index, and taking only the four next figures, will give 690 fathoms, 4140 feet, for the height of Kathmandu above the Tariyani. The observations with the thermometer, for the proper correction of those made with the barometer, are not complete; but they are not of great consequence, considering that the fundamental observations were not simultaneous, and were therefore liable to great error.
