The Book of Wheat 
An Economic History and Practical Manual of the Wheat Industry

First published in 1910, this volume was the result of fifteen years of study in the American Northwest. The author contributed to the burgeoning field of industrial and economic history, providing a practical manual for the entirety of the wheat industry at the time. Whilst smaller studies had been published before, this was the first general work on the subject, covering topics including the wheat plant, cultivation, diseases, marketing and production. It was of particular interest to growers, dealers and millers and was accessible to popular readers, students, instructors and experimenters.
