Then King Lud was very sad at heart, because he knew not how to free his land from the dismal plagues. He called together all the nobles of his kingdom, and asked counsel as to what he should do in the midst of these afflictions. And they all advised him to go to France and seek the advice of Llevelys his brother, king of that land. So they made ready a fleet in secrecy and silence, lest the Coranian race should learn the cause of their journey; and Lud, with some of his chosen followers, set his face towards France. When Llevelys saw his brother's ship approaching, he went out to meet him, and embraced him with much joy. Then King Lud told him the purpose of his errand; and King Llevelys thought a while, and, being very wise, soon discovered the cause of those dismal plagues. But they dared not talk freely about them to each other, lest the wind should catch their words, and the Coranians have knowledge of their discourse. So Llevelys caused a long horn to be made of brass, and through this horn they discoursed. But whatever words they spoke into the horn one to the other neither of them could hear anything but harsh and unfriendly words. Then Llevelys saw that there was a demon in the horn thwarting all their purposes, and caused wine to be put in to wash it out; and through the virtue of the wine the demon was driven away. When this was done, Llevelys told his brother through the horn that he would give him some insects, which he must take and bruise in water. And when he returned to his kingdom he must call together all the people, both of his own race and the Coranians, as though with the idea of making peace between them. And when they were all together he must take the charmed water made with the bruised insects, and cast it over all alike. And the water would poison the race of the Coranians, but it would not harm those of his own people.
