Everyone of these stories makes use of the macabre familiar--army ants, were-wolves, monstrous blobs, etc. But here, instead of being time worn, they're time honored. The werewolf story is a howl about a boy/werewolf pup. The army ant story is by Will Jenkins, probably the best treatment that device has ever had. There is even a wickedly mean stepmother (you can't hardly find one in a juvenile any more) who gets absorbed into a pinpoint of light. The appetite for pleasantly presented horror is seldom so well satisfied in books anthologized especially for young readers where the appetite is big. Monster Museum is an excellent companion to Hitchcock's Ghostly Gallery and Haunted Houseful.
