One might raise the reasonable contention that, although fen drainage did not increase agricultural productivity from a pre-drainage base of zero productivity, drainage did “improve the quality” of the land involved. From this point, one might posit the scenario of increased supply of fertile land; increased supply of grain; and, other things equal, decreased price of grain. Alternatively, Professor De Vries suggests the following: “This capital-intensive form of land acquisition was highly sensitive to the economic climate. With the downturn of agricultural prices after the mid-seventeenth century drainage activity diminished rapidly. In certain regions, most notably the Dutch Republic, the new land directly affected the supply of agricultural products, but in Europe as a whole it can be said that land augmentation of all types was no longer the chief avenue to increased supply. If the land area cannot be increased without undergoing great expense, there is but one alternative; increasing the productivity of the land, which chiefly takes the form of adopting more intensive crop rotation systems.” Vries, Jan De, The Economy of Europe in an Age of Crisis, 1600-1750 (Cambridge, 1976), 38CrossRefGoogle Scholar.

15 N.B., although the series reveal for 1620-9 to 1640-9 a relative shortage in Europe, there is no evidence of an export response by England in this period.

16 More generally speaking (leaving the grain market for a moment) we perceive in the literature a questioning of the prime significance of the expansion of foreign trade to the development of seventeenth-century England, e.g., “while foreign trade expanded in this period, its level was lower than that of internal trade, and there is no evidence to show that it grew faster. Domestic commerce, therefore, may very well have played the dominant role.” Reed, Clyde C., “Transactions Costs and Differential Growth in Seventeenth Century Western Europe,” Journal of Economic History, XXXIII (March 1973), 184Google Scholar.

45 “Closed” in the sense of insignificant grain export or grain import - thus excluding foreign market demand from the domestic demand function. Of course, in the general sense, the economy was open - witness the colonial trade and postwar Navigation Laws.

46 One may note the emergence of large scale graziers in Leicestershire in the post-war period. The assumption, however, of a fixed supply of land suitable for pasture and/or tillage remains in force. Furthermore, coincidentally with Leicestershire being turned to pasture much of East Anglia was adopting the sheep-corn-fodder crop innovations which would more than offset the demise of Leicestershire grain production.

55 One may question what impact the Navigation Laws and, specifically, the corn bounties had on this observed, dramatic upsurge in grain exportation. Although it is certainly difficult to isolate this factor, it would seem that a substantial surplus emerged prior to the institution of corn bounties, i.e., the bounties were instituted in response to a growing agricultural surplus created by the adoption of new techniques (see below for comments of a contemporary describing this relationship).
