Note 27 — INTRODUCTION.

I do not mention some well-known books treating of medieval husbandry and social history, because I am immediately concerned only with those works which discuss the formation of the medieval system. Thorold Rogers, History of Agriculture and Prices, and Six Centuries of Work and Wages, begins with the close of the thirteenth century, and the passage from medieval organisation to modern times. Ochenkovsky, Die wirtschaftliche Entwicklung Englands am Ende des Mittelalters, and Kovalevsky, England's Social Organisation at the close of the Middle Ages (Russian), start on their inquiry from even a later period.
