These events made the giant treat his visitors on their next arrival with more civility; besides, he had no more poisoned darts. He once more inquired why they had come, and when he realised that Kilhugh was determined to marry Olwen, he made him promise that he would do all that he required of him in return for his agreement to the marriage. Kilhugh, mindful of Olwen's warning that he was to agree to perform whatever her father proposed, gave a ready promise, and bade him ask away. Then did Thornogre Thistlehair propound to him forty Impossible Things, of which these seven are the chief: Firstly, he must gather nine bushels of flax sown hundreds of years ago in a field of red earth, of which never a seed had sprouted. Not one grain of the measure must be missing, and they must be sown again in a freshly ploughed field to make flax for Olwen's wedding veil. Secondly, he must find Mabon, the son of Modron, who was stolen from his mother when three days old, and had not since been heard of. Thirdly, he must find the Cauldron of Cruseward the Cauldron-Keeper, in which, if one tries to cook food for a coward, one may wait for ever for the water to boil, but if for a brave man the meal is ready directly it is placed therein. In this cauldron must all the food for the wedding feast be prepared. Fourthly, since the giant must shave for the wedding, he must obtain for a razor the tusk of the Boar-headed Branch-breaker, which to be of any use must be taken from his skull while he yet lived. Fifthly, since the giant must wash his hair, all matted together as it was, for the wedding, he must bring to him the Charmed Balsam kept by the Jet-Black Sorceress, daughter of the Snow-White Sorceress, from the Source of the Brook of Sorrow, at the edge of the Twilight Land. Sixthly, that the giant's hair might be smoothed and combed he must bring the scissors and the comb that are found between the ears of Burstingboar, the Wide-Waster, since they alone would perform the operation without breaking. Seventhly, he must obtain the sword of Garnard the Giant, since that alone would kill the Wide-Waster, from whom, unless he were killed, the comb and scissors could never be obtained. When he had made an end of speaking, the giant jeered at the Prince, who, unless he could do all these impossible things, might never wed his daughter. But Kilhugh answered with a high heart: "I have knights for my companions, horses and hounds, and Arthur is my kinsman. I shall do all that thou requirest, thou wicked giant, and shall win thy daughter, but thou shalt lose thy life." IV. Two of the Impossible Tasks are fulfilled Scarcely had the Seven Champions left the castle of Thornogre Thistlehair when they were joined by the fair-haired son of the shepherd, who had lived all his life in the chest. Eager to make a great name for himself he implored them to let him accompany them, which accordingly they did. Then they turned their faces towards Arthur's castle.
