By the end of Volume I, Unca has instructed the Indians to come back to visit her the following week for further instructions. She takes this time to reconsider what she had said to the Indians and how she should continue on with them. She also explored the island and discovered an extraordinary four footed animal. It was the size of a large dog, with long legs, a slender body, it had uncommonly large eyes which projected far from its head, and two rows of sharp but short teeth. This creature excited Unca's curiosity so she followed it. Other animals who were larger than it, fled at the sight of it. It came to a grassy area and extended itself as if dead, with eyes shut and lips closed. She sat down at some distance to watch it. The hair on his body was thick and long, five or six inches (152 mm), and formed bunches of clusters. A great number of field mice came up to him and began nibbling at the clusters of hair. It continued to lie still until a considerable number of mice had employed themselves among it. He then got up and shook violently, but the mice were stuck on him. He turned around, extended his long neck and began eating the mice greedily. In a few minutes he ate near three hundred of them because his body was almost covered in mice. Unca's curiosity was satisfied.
