The emperor died--by poison--before he could see his cherished project put into execution, but he had been a very thorough calculator, and a builder who believed in permanency. He had foreseen that when the granary was full, and the screw-jacks were turned beneath the cost of living, there would probably be efforts made by unwashed, untutored, unenlightened mobs to rape his storehouse. So he had made the little platform at the top a veritable fortress of a place, such as a handful of men could hold against a hundred thousand. There was no known entrance to the granary above ground, except on the ground level, where a huge stone gateway frowned above a teak-and-iron door. Above that door there were galleries, and fortalices and cunningly invented battlements in miniature, from behind whose shelter a resolute defending-party could pour out a hundred different kinds of death on a hungry crowd. The place was naturally fire-proof and naturally cool--as far as any building can be cool in Central India. It was a first-class, ideal powder-magazine, if useless as a granary; and the last new conquerors of India had hastened to adopt it as a means of storing up the explosive medicine with which they kept their foothold. Naturally, none but White soldiers, and a very few of the more trusted natives, had ever been allowed to go inside the powder-magazine. The secret passages beneath it had never been intended for public convenience or information. They had been designed as a means of rushing defenders secretly into the granary, and they connected with a tunnel underneath the palace that had just been burned. They also connected with the outer wall in such a way that defenders from the ramparts might be rushed there too, if wanted in a hurry. But, since there never had been corn kept in the granary, and nobody had ever had the slightest need to force an entrance, the knowledge even of the existence of the passages had become barely a memory, and there was not a man living in Jailpore who knew exactly where they began or where they ended. There was a man outside who knew, but none inside. The point about the powder-magazine which most appealed to Brown--next after his knowledge of its contents, mineral and human--was the fact that the little platform at its summit overlooked the city-wall, and that the side of the granary actually touched the wall on the side of the city farthest from where he sat and spied it out. Ten men on that protected platform, he thought, might suffer from the sun, but they could hold the building and command a good-sized section of the city ramparts against all comers.
