FOOTNOTES
[222] Senator Arthur Capper in an address delivered before the Highway Transport Conference, New York, 1920, said: “A recent investigation showed over 75 per cent of the Middle Western farmers bought their cars not for pleasure, but for business.” But he did not say how they use them. He did, in the same address, say, “A good road, plus a good motor truck, begets almost six motor trucks in any community and in any locality.” Emulation and rivalry are great selling agents.
[223] After the above was written there appeared in the New York Herald this statement: “This country consumed in May (1922), more than 13,000,000 barrels of gasoline. This is a matter of some 700,000,000 gallons.” The article goes on to calculate that in the use of this gasoline there was a travel of 10,000,000,000 car miles, and “at an average of four persons to the car, 1,600,000 individual motor trips around the world (in distance) in May.” The United States Bureau of Mines gives the domestic consumption of gasoline in the United States for 1921 as 4,516,012,979 gallons, an average of only about 7,000,000 barrels per month.
