Waterhouse found a worm-eaten copy of the Encyclopedia Qwghlmiana in a bookshop near the British Museum a week ago and has been carrying it around in his attache case since then, imbibing a page or two at a time, like doses of strong medicine. The overriding Themes of the Encyclopedia are three, and they dominate its every paragraph as totally as the Three Sgrhs dominate the landscape of Outer Qwghlm. Two of these themes are wool and guano, though the Qwghlmians have other names for them, in their ancient, sui generis tongue. In fact, the same linguistic hyperspecialization occurs here that supposedly does with the Eskimos and snow or Arabs and sand, and the Encyclopedia Qwghlmiana never uses the English words "wool" and "guano" except to slander the inferior versions of these products that are exported by places like Scotland in a perfidious effort to confuse the naive buyers who apparently dominate the world’s commodity markets. Waterhouse had to read the encyclopedia almost cover-to-cover and use all his cryptanalytic skills to figure out, by inference, what these products actually were.
