From the county of Keck, Van Vleck is a "very small bug" that opens which of Dr. Seuss's books?

The Sleep Book start with a small bug, named Van Vleck, yawning. “The news just came in from the County of Keck, That a very small bug by the name of Van Vleck, Is yawning so wide you can look down his neck." As the book unfolds, Van Vleck's yawn leads to a chain reaction of yawns, putting “ninety-nine zillion nine trillion and two” creatures to sleep.
