THE expedition undertaken in the summer of 1909 by the Duke of the Abruzzi to the head of the Baltoro and the Godwin Austen glaciers in the Karakoram was o essentially a mountaineering expedition. On the way out the longer summer route was followed across the Punjab Himalayas over the Zoji-La (11,230 feet), and down the valleys of the Dras and of the Indus, to Skardu, the capital of Baltistan. Here the route quits the Indus to ascend the Shigar and Braldoh valleys up to Askoley, the last inhabited spot, after which the glacier region is entered. While traversing Baltistan the expedition had the opportunity of seeing much of the Balti population and of photographing several groups of them. There can be no doubt that the great majority of the Baltis belong to the Aryan stock, and not to the Mongol-Thibetan, as ha? been stated by all English writers on the subject. The distinguished Hungarian anthropologist Ujfalvy had already demonstrated their close affinity to the Dards by comparative anthropometrical measurements.
