terraced and revetted and irrigated till every yard is made productive. Here and there dotted about in clusters all over the plain are square-built two storey mud and timber houses, standing in the shade of gigantic walnut and mulberry trees. Up on the hillsides surrounding the Maidan basin are wild olives in wide-grown clumps, almost amounting to forest, and occasional pomegranates. Higher still are the blue pines; but below on the shelving plains are nothing but fruit trees. Rajgul Valley lies north of Maidan, from which it is separated by a steep valley and well-wooded spur, eight to nine thousand feet high, and west of the Bara Valley, which it joins at Dwatoi. It is long, four to at its widest, and has an elevation of . It is inhabited by the Kuki Khel Afridis. The Waran Valley is another valley about the same size as Maidan, lying east of it, and separated from it by the Tseri-Kandao Pass. It was the home of the Afridi mullah Sayad Akbar. and is the country of the Aka Khels. After the junction of the Rajgul and Maidan drainage at Dwatoi, the united stream receives the name of Bara, and the valley through which it flows down to its exit in the Peshawar Valley is also known by this name. The elevation of the valley is from . at Dwatoi to 2000 at Kajurai; on the north side it is hemmed in by the Surghar range, which divides it from the Bazar Valley; on the south lies another range dividing it from Maidan and the Waran Valley.

The Mastura Valley occupies the southern half of Tirah, and is inhabited by the Orakzais. It is one of the prettiest valleys on the frontier, lying at an elevation of . The Orakzais live, for the most part, in the Miranzai Valley, in the winter, and retreat to Mastura, like the Afridis, during the summer months. The chief passes in Tirah are the Sampagha Pass (6,500 ft), separating the Khanki Valley from the Mastura Valley; the Arhanga Pass (6,99E ft.), separating Mastura Valley from Maidan; Saran Sar (8,650 ft), leading from the Zakka Khel portion of Maidan into the Bara Valley;
