With the fuller knowledge we now possess it is possible to give more in detail the physical features of the country through which the Relief column of Peshawur passed. Skirting the broad open plain in which Peshawur is situated is a range of mountains varying from 3,000 feet to 6,000 feet in height, and known locally and collectively as the "border hills," for, generally speaking, the British border runs along the foot of this range. Beyond the border range lies the richly cultivated Swat Valley, varying in width from two miles to three miles, and having an extent of some thirty-six miles lengthways. Down this valley flows the Swat River, a considerable stream at all times of the year, but after the snows begin to melt, and the summer rains burst, a large and rapid river. Some estimate of the size of the river may be gained by noting that at the point first bridged by our troops, it is about half-a-mile wide from bank to bank, being split up into seven channels each requiring a separate bridge. The north side of the Swat Valley is formed by the Laram range of mountains varying from 5,000 feet to 6,000 feet in height. Beyond the Laram range we come to the southern extremity of the Principality of Dir, down the main valley of which flows the formidable and treacherous Panjkora River. This river which one day is fordable may the next be found a roaring torrent, many feet deep; indeed on one occasion it rose fourteen feet within a few hours, with little or no warning. The Panjkora Valley throughout its length is narrow, with steep rocky spurs constantly running down to the water's edge, and except in the depth of winter when the water is at its lowest, was not suitable, without extensive road making, for the passage of troops. Lying to the east of the Panjkora Valley, and separated from it by high ranges, we find the broad, open, fertile valleys of Jandul and Bajaur, the former of these being the original home and limited territory of the chief Umra Khan, against whose power the British expedition was mainly directed. Skirting the north end of the Jandul Valley comes the Janbatai range, varying from 6,000 feet to 10,000 feet in height, crossing which we drop into a series of narrow, rocky valleys which betoken the approaches to some great mountain range. Such are the Baraul and Upper Dir Valleys, with no room for cultivation on any scale, and barely capable of supporting a miserably poor and backward race. Running transversely across the north corner of Dir territory we come to the mighty range of mountains, from 10,000 feet to 20,000 feet in height, over which the Lowarai Pass alone gives military access to the Chitral Valley. The Chitral Valley is itself very narrow and rocky, much on a par with the Panjkora Valley, and was, till a track was cut, very difficult for the passage of troops.
