Note 36 — Chapter III · THE POSSIBILITIES OF AGRICULTURE.
Reading edition
Average area under wheat in 1853-1860, 4,092,160 acres; average crop, 14,310,779 quarters. Average area under wheat in 1884-1887, 2,509,055 acres; average crop (good years), 9,198,956 quarters. See Professor W. Fream’s Rothamstead Experiments (London, 1888), page 83. I take in the above Sir John Lawes’ figure of 5·65 bushels per head of population every year. It is very close to the yearly allowance of 5·67 bushels of the French statisticians. The Russian statisticians reckon 5·67 bushels of winter crops (chiefly rye) and 2·5 bushels of spring crops (sarrazin, barley, etc.).
