Bran an' 'is lads went on a trip whaen...

Thereupon Bran went from him. And he saw an island. He rows round about it, and a large host was gaping and laughing. They were all looking at Bran and his people, but would not stay to converse with them. They continued to give forth gusts of laughter at them. Bran sent one of his people to the island. He ranged himself with the others, and was gaping at them like the other men of the island. He kept rowing round about the island. Whenever his man came past Bran, his comrades would address him. But he would not converse with them, but would only look at them and gape at them. The name of this island is the Island of Joy. Thereupon they left him there.
