enclosure movement continued vigorously in the seventeenth century is conclusively established, and when this fact is known the impossibility of estimating the comparative rate of progress of the movement in the preceding century is of no importance. Upon one point at least, the evidence is almost all that could be desired. The material for a comparison of the prices of wheat and wool throughout the most critical portion of the period has been made accessible by Thorold Rogers.[11] It is to this material that the defenders of the theory that enclosures are explained by the price of wool should turn, for they will find a fall of price where they assume that a rise took place. Instead of an increase in the supply of wool due to a rise in its price, there is indicated a fall in the price of wool due to an increase in the supply. The cause of the increase of the supply of wool must be sought outside of the price conditions. Acknowledgment should here be made of my indebtedness to Dr. V. G. Simkhovitch of Columbia University, without whose generous help this study would not have been planned, and whose criticism and advice have been invaluable in bringing it to completion. Professor Seager also has given helpful criticism. Professor Seligman has allowed me the use of books from his library which I should otherwise have been unable to obtain. For material which could not be found in American libraries I am indebted to my mother and father, who obtained it for me in England. Footnotes: [1] V. G.
