Odd book titles

This week I came across a few unusual book titles while proofreading for Distributed Proofreaders. The first : Men's Sewed Straw Hats by the US Tariff Commission. I wonder if there's another edition for woven hats and what not...although, it's hard to believe there's an entire book about taxing straw hats. Another odd title: Hemp hurds as paper-making materials. I didn't read the text, but the summary says you can make paper from the flax-like material in hemp. And the last one: A Treatise on the Cohabitation of the Faithful with the Unfaithful. I'm guessing it's about religious faith, rather than infidelity; whatever the content, I'm sure there's heavy religious overtones. Many of the old texts preach morality. For instance, I proofed a book-length essay called Usury which used frequent Bible citations as evidence of the evils of usury.
