Herblore of the Shire

From Tolkien Gateway

Herblore of the Shire was a book written by Merry Brandybuck, one of several treatises he authored after his return from the War of the Ring, but before he became Master of Buckland.

The book discussed the origins and history of the Hobbits' 'art' of smoking Pipe-weed, tracing it back through Tobold Hornblower (who introduced it to the Shire) to its ultimate origins in Middle-earth, in the lands along the southern banks of the Anduin.[1]

This book was one of the important tomes kept in the library of Bucklebury, perhaps one of those important works that weren't copied into the Red Book.[2]
