I thought I had met all the classes in the Indian Army. But one day at Sheikh Saad, when I was half asleep with the heat, I opened my eyes to see a company of unfamiliar faces. They were not unfamiliar individually. I had met the double of each of them; yet collectively they were unfamiliar. In the first platoon I could have sworn to a Gurkha, a Chinaman, a Tibetan, a Lepcha of Sikkim, a Chilasi, and an undoubted Pathan with a touch of the Turki in him. Whether in eye, nose, complexion, or the flatness of the cheek there was something Mongol in them all, while in at least half there was a suggestion of the Semitic. The Lepcha had the innocent jungly glance of the cowherd of Gantok or Pemiongchi; the Chinaman with the three-cornered eyes was an exaggeration of type; the Pathan would have passed muster in the Khyber Rifles. They were all fairer than many Englishmen after a year of Mesopotamia, and they spoke a kind of mongrel Persian with a Tibetan intonation. The regiment disembarked from the steamer and filed out to the rest camp behind my tent in the intense heat of a September afternoon. It was too hot to sleep, much too hot to wander about and ask questions. If it had been cooler I should have gone out and talked to one of the regimental officers. But 118 degrees in the shade under canvas kills curiosity. I remember there was a dog under the outside fly of my tent, and for half an hour I mistook its breathing for the engine of a motor-car, but never quite rose to the effort of getting up to see if the machine could not be persuaded to move on. Happily there was no need to go out and ask who these men were. I soon tumbled to it, though I had never seen the breed until they landed in the blinding glare of Sheikh Saad. The history of the Hazaras is written in their faces. They are of Mongol origin, though the colony is settled near Ghazni in Afghanistan. I had heard how they came there, but had forgotten the story, only remembering that the Mongols had married wives of the country of their adoption. Hence the curious blend of the Central Asian and the Jew in the crowd that was stumbling up the bank. A little reflection solved the puzzle in spite of the heat. [Illustration: THE HAZARA.]
