Hastening from the spot, Felix came across the artillery, which consisted of battering rams and immense crossbows; the bows were made from entire trees, or, more properly, poles. He inspected these clumsy contrivances with interest, and entered into a conversation with some men who were fitting up the framework on which a battering ram was to swing. Being extremely conceited with themselves and the knowledge they had acquired from experience only (as the repeated blows of the block drive home the pile), they scarcely answered him. But, presently, as he lent a hand to assist, and bore with their churlishness without reply, they softened, and, as usual, asked him to drink, for here, and throughout the camp, the ale was plentiful, too plentiful for much progress. Felix took the opportunity and suggested a new form of trigger for the unwieldy crossbows. He saw that as at present discharged it must require some strength, perhaps the united effort of several men, to pull away the bolt or catch. Such an effort must disconcert the aim; these crossbows were worked upon a carriage, and it was difficult to keep the carriage steady even when stakes were inserted by the low wheels. It occurred to him at once that the catch could be depressed by a lever, so that one man could discharge the bow by a mere pressure of the hand, and without interfering with the aim. The men soon understood him, and acknowledged that it would be a great improvement. One, who was the leader of the gang, thought it so valuable an idea that he went off at once to communicate with the lieutenant, who would in his turn carry the matter to Baron Ingulph, Master of the Artillery. The others congratulated him, and asked to share in the reward that would be given to him for this invention. To whose "war" did he belong? Felix answered, after a little hesitation, to the king's levy. At this they whispered among themselves, and Felix, again remembering the carters' caution, said that he must attend the muster (this was a pure guess), but that he would return directly afterwards. Never for a moment suspecting that he would avoid the reward they looked upon as certain, they made no opposition, and he hurried away. Pushing through the groups, and not in the least knowing where he was going, Felix stumbled at last upon the king's quarters. CHAPTER XVIII THE KING'S LEVY
