The Shutargardan route having been finally closed, it has, of course, become imperative to open up the Gundamak and Khyber line of communication, and General Macpherson, with a force already detailed, is now engaged upon that work. From Cabul to Butkhak the road runs in a due easterly direction through the Cabul plain, and is so good that cavalry can travel at a gallop over it. To the south a range of hills shuts out the valley through which the Logar river runs after passing through the Sang-i-Nawishta defile; and when this range is passed a swampy _maidan_ is entered upon, which gradually changes into a dry, open plain, overgrown with short tufts of coarse grass. The Logar river is crossed at right-angles by the road which is carried over a stout masonry bridge of six arches. The river is turbid, but its current runs at about four or five miles an hour to its junction with the Cabul stream, creeping away under the high hills which bound the view to the north, two or three miles away. Irrigation channels are cut from the Logar, and these serve as a source of fertility to the fields about Butkhak, a walled village prettily situated in its orchards, with shallow streams running near the walls. Butkhak is to be the first post on the road, its garrison consisting of forty rifles, who will be placed in a square enclosure easily capable of defence. The telegraph wire has been already laid to this village from Sherpur cantonments. The hills which bound the Cabul plain to the north and south close in near Butkhak, and to the east sink down 1,000 feet, affording the only out-look towards Jugdulluck. One can see even from Cabul that this break in the continuous ranges which guard the plain must give an outlet into the Jellalabad Valley, and it is accordingly in this direction that we shall unite our little army with the supporting force that has marched out from Peshawur through the Khyber. The ordinary road from Butkhak to Jugdulluck, and thence to Gundamak, is through the Khurd Cabul Pass; but this has been represented of so formidable a kind, that alternative routes have been sought. Moreover, the Khurd Cabul Road makes a considerable detour to the south, and thus adds many miles to the distance, measured as the crow flies. To satisfy himself as to the practicable nature, or otherwise, of other routes, General Roberts, accompanied by Colonel Macgregor and a few members of his Staff, left Sherpur early on Sunday morning, and rode over to Butkhak, where General Macpherson was encamped.
