These speculations end as we come, not to the castle, but to a semicircular palisade inclosing the regular gate on the landward side. This palisade is too high to scramble over; the piles are too sharply pointed and stout enough to stand considerable battering. This outwork is the barbican--the first of the long series of obstacles awaiting the foe. Of course, it could not be defended in a regular siege, but its purpose is to stop any surprise attack long enough to enable the garrison to rally, close the great gate, and man the walls. The whole crowd of folk now entering make for the heavy wooden barrier which is just being thrown open by a rather sleepy porter. Since it is a time of profound peace, he lets them all stream inside, merely requiring everyone to leave his weapons in his custody. We pass unchallenged, thanks to the kind _fée_ aforementioned, who has rendered us as invisible as the owner of Gyges's ring. If, however, we had been guests of noble rank, we would have proceeded onward to the inner gate and rung loudly on a heavy metal gong hanging there. One of the baron's squires would then have greeted us. If we had been the baron's equal or superior in the social scale, Conon himself would next have come down to lead us in; if somewhat inferior, we would have been conducted by the squire to the great hall, where we would have removed hood and gloves before the magnate presented himself. But we have much to examine ere we penetrate the seigneurial hall. Once inside the barbican, one discovers that between this extreme barrier and the fortress proper there is another open space with a road, and another place for equestrian exercises extending from the Claire straight over to the abrupt slopes of the Rapide. The palisades run all the way from river to river. This space within the barbican forms the lists, where two young sergeants are breaking in a balky stallion. The lists are a great convenience in peace time, but the real utility is in war, and they are even more important in the castles that have land on every side. They supply a good road by which men can be hurried round the castle circuit in reasonable safety. On the other hand, if the enemy suddenly forces the barriers, he finds himself most awkwardly in a limited space between the palisade and the castle moat, with all the arbalists (crossbows) playing on him from the walls above. Inside the lists and next to the masonry walls runs the moat. It is some twenty feet wide, partly filled now with scum-covered rain water. In the spring the varlets have great joy here hunting frogs, but as the year advances it assuredly breeds mosquitoes. It constitutes, however, another formidable barrier to an enemy, and that is its sole object.
