It is alleged that from these lower vaults there is an underground passage leading from the castle to a secret sallyport at the foot of the precipice by the Rapide. If a passage exists, however, it is known only to Conon and a very few trusted retainers. But not all such stories are false; many castles have such secret passages; and at Coucy they are quietly planning to introduce a rather elaborate system of the same. Quite possibly St. Aliquis possesses something of this nature. Far pleasanter is it now to ascend from the main hall through a couple of stages of upper and airier chambers (now used as apartments by part of the castle folk) until by a dizzy ladder we reach the summit of the donjon itself. Here on one edge of the broad platform is a little round turret carrying us still higher. From the turret flutters the orange banner of St. Aliquis, with some kind of a black dragon (in memory, possibly, of the viking raid) broidered upon it, and the arrogant legend of the noble family, "Rather break than bend." To lower this banner were a horrid disgrace. Never is it to be struck unless the castle surrenders, when it will be sadly flung into the moat. Under the flagstaff is a stout projecting beam rigged with a pulley. Here is a gibbet in case the baron wishes to hang offenders as a warning for the countryside. Fortunately, however, Adela has a dislike to seeing the corpses dangling, and has persuaded Conon to order his recent hangings at the ordinary gallows across the Claire by the village. On the flag turret is always a watchman; day or night some peasant must take his turn, and even in peace he has no sinecure. He must blow on his great horn at sunrise, at "cover fire" at night, when the baron's hunt rides out and returns, and again when a strange retinue approaches the gate. The whole wide countryside spreads in a delightful panorama below him at present, but on winter nights, when every blast is howling around the donjon, the task is less grateful. No wonder that peasants impressed for this service complain that "watchmen have the lot of the damned." So back through the donjon and again to the castle court. The donjon is purely military. In times of peace it is a mere storehouse, prison, and supplementary barrack for the seigneur's people. In war it is the last position where the garrison can stand desperately at bay. A hundred years earlier Adela and her sister-in-law, Alienor, would have lived out most of their days in the cheerless dark chambers directly above the main hall. Now they are more fortunate. They dwell in the elegant Gothic arched _palais_. [Sidenote: Great Hall of the Palais]
