In the old days knowledge of map-making was, in the army, confined to the Royal Engineers. A late inspector-general of fortifications, General Sir Richard Harrison, R.E., told me that in the China War of 1860 only two officers, he and Captain, afterwards Lord, Wolseley, in the Anglo-Indian Army there could make a military sketch, and very few others were able to understand it when made. Nowadays every officer can map any country and during the drill season is called upon to furnish at least one sketch. The civil engineers brought out in 1905-6 to Hong Kong to survey the route of the railway to Canton told me that in the British Hinterland they made no maps, and contented themselves with such annual military sketches of the country done by officers of the garrison. And these they found accurate enough for railway laying. The task that I was now engaged on, which was for the purpose of revising the military route-book of Eastern Bengal, was set me as part of my ordinary work; I being the nearest available officer. The country through which my road lay for the next sixty miles was open, level, and well-cultivated, dotted with groves of feathery bamboos and the typical, compact, thatched villages and farm-buildings of Bengal. As usual, in India, the fields were not divided by hedges or any obstacles. Even at that season of the year the country-side looked green, in striking contrast to other parts of the land then when the hot weather was drawing near. And always along and parallel to my route lay the wall of the mountains thirty or forty miles away, rising abruptly from the plains in a confused jumble of rugged hills overtopping each other until they culminated in the long white crest of Kinchinjunga, which now and then at sunset or dawn towered over them all above the clouds and seemed to float detached in the sky. At the first _dâk_ bungalow which sheltered me after leaving Jalpaiguri we had a splendid view of this magnificent mountain; and I overheard my orderly, Draj Khan, who had been with me in Darjeeling and had seen it from there, explaining to the Rajput sepoy with us that it was composed entirely of ice. The latter, a man from the sandy deserts of Bikanir, never having seen snow or more ice than a small lump in some native liquor-dealer's shop in the bazaar, refused to believe Draj's statement and appealed to me. I found it no easy task to explain the mystery of the Everlasting Snows to the intellect of this more or less untutored savage; and I fear that he understood me even less than he did Draj Khan's explanation. Natural physical phenomena that we accept as articles of belief we find not so easy to make clear to the minds of uneducated people. The Pathan subhedar-major of my regiment rejected my account of the causes of earthquakes in favour of his own theory that they arise from the movements of a dragon slumbering in the centre of the earth and occasionally shaking itself or turning round in its sleep.
