The Hidden Treasure filling their goatskins. My four policemen in their light- blue uniforms made no discord in the picture as they stood to water their horses. The sentry from the square fort had seen them. The small flag fluttered at the top of the keep in a light breeze from the north. Always, from the earliest days of built houses, such a chain of towers, spaced at convenient day's journeys, has probably linked these valleys with government: it is the only way in which the country can be held: and probably the same sort of sentry has watched the flocks and the tribes from his evening doorstep in the valley of Aiwan for longer than one would imagine, looking at the treeless nomad cornland now. The tents of the Aiwan were arranged in two or three rows in the stubble-fields, and the chief who owned the first and best of them came out to greet and welcome us with more cordiality than I had ever seen since travelling with an escort. I began to notice here a great difference in the tribes, and a far larger measure of subservience than among the Bedrei and Malikshahi: and the sergeant explained it next day by telling me that here they do not, as in the region of Kebir Kuh, own their own land, but the landlord is the Shah, who sends his overseers to take a third of their harvest every year. Something of the tribesman has gone, some- thing of the peasant has crept into their manner. I regretted it, though no doubt it makes them easier to govern. It is not the turbulence of the tribesman that one admires: but the virtues that go with his turbulence, so that the two are associated together. His treasure is the freedom of his spirit: when he loses that, he loses everything. And if civilization is that state in which the unshackled mind bows voluntarily to Law, freedom and discipline are the two wheels on which it runs. The tribesman does bow to a law of his own, but his apologists must admit that discipline [180]
