MOUNTAINS, HILLS AND PLAINS

picture as seen in the cold weather from the plains of Rawalpindi, Jhelam, and Gujrat. The Outer Himalaya is continued beyond the gorges of the jhelam and Kishnganga rivers in Kajnag and the hills of the Hazara district. Near the eastern extremity of the Dhauladhar section of the Outer Himalaya it sends out southwards between Kulu and Mandi a lower offshoot. This is crossed by the Babbu (9480 feet) and Dulchi passes, connecting Kulu with Kangra through Mandi. Geologically the Kulu-Mandi range appears to be continued to the east of the Bias and across the Sutlej over Hattu and the Chor to the hills near Masuri (Mussoorie), a well-known hill station in the United Provinces. Another offshoot at the western end of the Dhauladhar passes through the beautiful hill station of Dalhousie, and sinks into the low hills to the east of the Ravi, where it leaves Chamba and enters the British district of Gurdaspur.

River Valleys and Passes in the Himalaya.— While these principal chains can be traced from south-east to north-west over hundreds of miles it must be remembered that the Himalaya is a mountain mass from 150 to 200 miles broad, that the main axes are linked together by subsidiary cross chains dividing the head waters of great rivers, and flanked by long and lofty ridges running down at various angles to the gorges of these streams and their tributaries. The typical Himalayan river runs in a gorge with mountains dipping down pretty steeply to its sides. The lower slopes are cultivated, but the land is usually stony and uneven, and as a whole the crops are not of a high class. The open valleys of the Jhelam in Kashmir and of the Bias in Kulu are exceptions. Passes in the Himalaya are not defiles between high cliffs, but cross the crest of a ridge at a point where the chain is locally depressed, and snow melts soonest. In the Outer and Mid Himalaya the line
