Unvaryingly, up to XYZ, Brown proceeds through the alphabet according to the pattern established in an old ball-bouncing chant, But there the appeal is the challenge to fill in a properly initialed word without missing the beat. The interest is considerably less when it's all done for you--even though Brown's choice of quarters and commodities contains some dreamlike images (""We live on a flagpole, and we sell fireworks. . . . We live in a kettle, and we sell kites"") and her fanciful drawings make the most of their airiness.
