Guide-books are so many that it seems probable we have more than any other country - possibly more than all the rest of the universe together. Every county has a little library of its own - guides to its towns, churches, abbeys, castles, rivers, mountains; finally, to the county as a whole. They are of all prices and all sizes, from the diminutive paper-covered booklet, worth a penny, to the stout cloth-bound octavo volume which costs eight or ten or twelve shillings, or to the gigantic folio county history, the huge repository from which the guide-book maker gets his materials.
