Access to Chitral from the north is therefore but a matter of practicable tracks, or passes, in two or three directions, and the measure of practicability under any given conditions can best be reckoned from Chitral itself.
In 1886 experiments were conducted, under certain restrictions, and the plant was grown in Norfolk, Kent and other counties with sufficient success to prove the entire practicability of raising tobacco as a commercial crop in England.
