A wonderful animal was sent to Ireland by the King of England. She resembled a mare, and was of a yellow colour, with the hoofs, of a cow, a long neck, a very large head, a large tail, which was ugly and scant of hair. She had a saddle of her own. Wheat and salt were her usual food. She used to draw the largest sled-burden by her tail. She used to kneel when passing under any doorway, however high, and also to let her rider mount.
