The significance of the strides made in agricultural productivity by which Mr. Hoover's food campaign was made possible and successful is brought out in the report of the Secretary of Agriculture for 1918: "The efforts put forth by the farmers and the agricultural organizations to secure increased production can perhaps best be concretely indicated in terms of planting operations. The size of the harvest may not be the measure of the labors of the farmers. Adverse weather conditions and unusual ravages of insects or plant diseases may partly overcome and neutralize the most exceptional exertions." ACREAGE UNDER CULTIVATION "The first year of our participation in the war, 1917, witnessed the Nation's record for acreage planted--283,000,000 of the leading cereals, potatoes, tobacco, and cotton, as against 261,000,000 for the preceding year, 251,000,000 for the year prior to the outbreak of the European war, and 248,000,000 for the five-year average, 1910--14. This is a gain of 22,000,000 over the year preceding our entry into the war and of 35,000,000 over the five-year average indicated. Even this record was exceeded the second year of the war. There was planted in 1918 for the same crops 289,000,000 acres, an increase over the preceding record year of 5,600,000. It is especially noteworthy that, while the acreage planted in wheat in 1917 was slightly less than that for the record year of 1915, it exceeded the five-year average (1910--14) by 7,000,000; that the acreage planted in 1918 exceeded the previous record by 3,500,000; and that the indications are that the acreage planted during the current fall season will considerably exceed that of any preceding fall planting."
