An even less imposing and younger-looking poetry collection than The Dog Wrote on the Window with His Nose (p. 167, J-43)--and all the better for it. Of the 25 selections, very few contain more than 25 words; one, by James Minor, consists solely of the word giddyup repeated sixteen times, but like several of the concrete bits included, it's the words' arrangement on the page that makes the image. (That, and the illustrators' extension--which also adds to Minor's ""OO OO,"" the entire text of a poem titled ""Pine at Night/ Cry of the Owls."") A. R. Ammons leads the list, numerically and lyrically, with four ""Small Songs""--for example, ""The reeds give/ way to the// wind and give/the wind away."" And Aruego and Dewey surpass their recent self-imitation in the witty illustrations; unlike the best of the poems, they don't quite take that last inspired step off the edge of the earth, but they do bounce the images about in a joyful demonstration of creative play.
