To begin by taking the most disadvantageous case: is it possible that the soil of Great Britain, which at present yields food for one-third only of its inhabitants, could provide all the necessary amount and variety of food for 41,000,000 human beings when it covers only 56,000,000 acres all told--forests and rocks, marshes and peat-bogs, cities, railways and fields--out of which only 33,000,000 acres are considered as cultivable?[35] The current opinion is, that it by no means can; and that opinion is so inveterate that we even see men of science, who are generally cautious when dealing with current opinions, endorse that opinion without even taking the trouble of verifying it. It is accepted as an axiom. And yet, as soon as we try to find out any argument in its favour, we discover that it has not the slightest foundation, either in facts or in judgment based upon well-known facts. Let us take, for instance, J. B. Lawes’ estimates of crops which were published every year in _The Times_. In his estimate of the year 1887 he made the remark that during the eight harvest years 1853-1860 “nearly three-fourths of the aggregate amount of wheat consumed in the United Kingdom was of home growth, and little more than one-fourth was derived from foreign sources”; but five-and-twenty years later the figures were almost reversed--that is, “during the eight years 1879-1886, little more than one-third has been provided by home crops and nearly two-thirds by imports.” But neither the increase of population by 8,000,000 nor the increase of consumption of wheat by six-tenths of a bushel per head could account for the change. In the years 1853-1860 the soil of Britain nourished one inhabitant on every two acres cultivated: why did it require three acres in order to nourish the same inhabitant in 1887? The answer is plain: merely and simply because agriculture had fallen into neglect. In fact, the area under wheat had been reduced since 1853-1860 by full 1,590,000 acres, and therefore the average crop of the years 1883-1886 was below the average crop of 1853-1860 by more than 40,000,000 bushels; and this deficit alone represented the food of more than 7,000,000 inhabitants. At the same time the area under barley, oats, beans, and other spring crops had also been reduced by a further 560,000 acres, which, alone, at the low average of thirty bushels per acre, would have represented the cereals necessary to complete the above, for the same 7,000,000 inhabitants. It can thus be said that if the United Kingdom imported cereals for 17,000,000 inhabitants in 1887, instead of for 10,000,000 in 1860, it was simply because more than 2,000,000 acres had gone out of cultivation.[36]
