From the book:
This is written from memory, unfortunately. If I could have brought with me the material I so carefully prepared, this would be a very different story. Whole books full of notes, carefully copied records, firsthand descriptions, and the pictures - that's the worst loss. We had some bird's-eyes of the cities and parks; a lot of lovely views of streets, of buildings, outside and in, and some of those gorgeous gardens, and, most important of all, of the women themselves. Nobody will ever believe how they looked. Descriptions aren't any good when it comes to women, and I never was good at descriptions anyhow. But it's got to be done somehow; the rest of the world needs to know about that country. I haven't said where it was for fear some self-appointed missionaries, or traders, or land-greedy expansionists, will take it upon themselves to push in. They will not be wanted, I can tell them that, and will fare worse than we did if they do find it.
