Clinging tight to my mother was a little baby.

Also, there was a girl, partly grown, who cautiously regarded us from one of the lower branches.

She was evidently my sister, or half-sister, rather.
My mother recognized me, but she warned me away when I started to climb into the tree.

Lop-Ear, who was more cautious by far than I, beat a retreat, nor could I persuade him to return.

Later in the day, however, my sister came down to the ground, and there and in neighboring trees we romped and played all afternoon.
