The scenery around Miru is indescribably beautiful, as it almost overhangs the Sutlej 3000 feet below, while beyond the river the mountain-slopes are densely wooded, yet often rocky and with every variation of form. A single peak, still streaked with snow, but too steep for much to lie, rises almost due opposite; behind which the summits of the chain south of the Sutlej rise to an elevation of upwards of 18,000 feet.
At Miru we found that we had completely left the rainy region of the mountains, and henceforward the weather continued beautiful. The change had been very gradual. At Serahan we had heavy rain; a rainy night at Tranda was succeeded by a brilliant day, till the afternoon, when it rained smartly for an hour. The next day was again fine, and at Miru, though the afternoon was cloudy, and a heavy storm was visible among the mountains across the Sutlej, only a few drops of rain fell. The transition from a rainy to a dry climate had thus been apparently very sudden, four days having brought us from Serahan, where the periodical rains were falling heavily, to a place at which there were only light showers. This was in part, of course, accident. Fine weather may, perhaps, have set-in in the interval in all parts of the mountains. In very rainy seasons, when the rain-fall in the outer Himalaya is considerably above the mean, heavy showers extend into Kunawar, at least as far as Chini; and careful meteorological observations would probably show that the transition of climate is a very gradual one, the snowy mountains and the great spurs which run towards the Sutlej collecting and condensing, as they increase in elevation, more and more of the moisture which is brought by the south-east winds from the Bay of Bengal.
[Sidenote: VEGETATION OF KUNAWAR. _August, 1847._]
Jacquemont, in the valuable journal of his tour in India, which has been published by the French Government, has observed that the passage of the ridge between Chegaon and Miru may be considered as producing a marked change in the vegetation. This change, as we have seen during our journey up the Sutlej, had long been going on, though very gradually and almost insensibly. Several circumstances combine to make the transition appear at this point more sudden than a careful calculation of the number of new species will prove to be the case. It is the first wooded ridge on the north side of the Sutlej over which the road passes, and it rises higher than any other part of the route east of Nagkanda. A considerable effect is also produced by several new arboreous or shrubby species making their appearance, as well as by the fact that the new forms, which day by day have insensibly been increasing in number, have at last begun to form a prominent feature in the country.
