Trees are beautiful. They fill up the sky. If you have a tree, you can climb up its trunk, roll in its leaves, or hang a swing from one of its limbs. Cows and babies can nap in the shade of a tree. Birds can make nests in the branches. A tree is good to have around. A tree is nice.

Mrs. Udry's first book, A Tree Is Nice, illustrated by Marc Simont, won the 1957 Caldecott Award for the most distinguished American picture book. Mrs. Udry is also the author of Glenda, Let's Be Enemies (also illustrated by Maurice Sendak), Mary Ann's Mud Day, The Mean Mouse and Other Mean Stories, and Thump and Plunk.
