Did the enchantment have any other effects? The accounts don't specify, but it's certainly possible that it was responsible for animal speech, and some of the more unusual types of flora and fauna. Robert R. Pattrick, a pioneer in the field of Ozian research, somehow had the idea that it was responsible for ALL magic in Oz, but I find that unlikely. The books have some references to magic-workers living there in the distant past, and the general suggestion in Baum's fantasy works is that civilization is what halts the use of magic (or at least severely hampers it; he does have a few stories in which there are active witches and wizards in the civilized world, one of them being John Dough and the Cherub).  Perhaps the enchantment, together with the desert isolating Oz from the rest of the world, is what prevented the encroaching of civilization, and hence allowed magic to continue to be practiced there. Many of the lands immediately across the desert from Oz have at least some magical properties, and some (Mo, for example) seem to be even MORE magical. Did Lurline also enchant some of these other lands? I think that's an issue that can be saved for a later post.
 His stay in Pokes is reported to have been around 500 years, however, which suggests he was already 200 by the time he set out from his father's castle to get married. Seems like a long time to wait, even in a deathless fairyland.
 The differences between Oz, its surrounding fairylands, and fully mundane lands like our own comprise a topic that I'll almost certainly be discussing in a future entry.
