After surmounting the Oonnye Pass, which is one of the principal defiles of the Hindoo Khoosh, we proceeded on the 20th to Gurdundew[=a]l, a distance from Uart of about six and a half miles. The road was a gradual descent, and very rugged, leading along the bases of barren rocks, till we debouched upon the river Elbon, as it is termed by the natives, but the Helmund or Etymander of the ancients. Even here, where the stream was in its infancy, the current was so strong, that while we were fording it, one of our baggage ponies laden with a tent was carried away by its violence, and, but for the gallant exertions of our tent-pitcher, we should have had to sleep in the open air for the rest of our journey; as it fortunately happened, both animal and load were recovered; and when properly dried, neither one nor the other were a bit the worse for their washing. On the 21st we encamped near the village of Kazee, after a march of nine miles along the right bank of the Helmund, which here flows in a south-westerly direction; we could procure no supplies whatever, either for man or beast, which was the more vexatious as we had a very hard day's work in prospect for the morrow, and were anxious to recruit ourselves and cattle before attempting it. We managed well enough in spite of our compulsory fast, and on the 22d we reached Kalloo, a distance of twelve miles, after crossing the steep and difficult pass of Hadjekuk, 12,400 feet high; as we approached the summit we found ourselves amongst the snow, and experienced some little inconvenience from a difficulty of respiration; though this pass was even higher than that of Oonnye, it does not possess the same abruptness and boldness of feature which render the latter so interesting and dangerous. The hills near the gorge were so strongly impregnated with iron as sensibly to affect the needle of the theodolite.
