That would never do," thought Ruth to herself as she looked at a fish-shop they were passing, "It's so wet and slippery I couldn't possibly carry it home. Perhaps Nurse doesn't really know what cats like best. Anyhow, I'm sure it's never tasted anything so nice as a Bath bun." A Bath bun was accordingly bought, carried home, and put carefully away in the doll's house. And now Ruth felt that she had an important piece of business before her. She spread out a sheet of the new writing-paper on the window-seat, knelt in front of it with a pencil in her hand, and ruled some lines. She could not write very well, and was often uncertain how to spell even short words; so she bit the end of her pencil and sighed a good deal before the letter was finished. At last it was done, and put into the envelope.
