And the way he read the letter, it said to him: Daddy, daddy, daddy, come home to us in the Rootabaga country where the pigeons call ka loo, ka loo, ka lo, ka lo, where the squirrels carry ladders and the wildcats ask riddles and the fish jump out of the rivers and speak to the frying pans, where the baboons take care of the babies and the black cats come and go in orange and gold stockings, where the birds wear rose and purple hats on Monday afternoons up in the skylights in the evening.
