Even before the war in Europe started, the tendency toward changing standards in food production was marked. In one of America’s leading periodicals, we read: “=Tree crops is the next big thing in farming=,” says J. Russel Smith, after =an 18,000–mile journey through the nut growing countries=. The man who is alert to changing food standards, who realizes how largely the cattle herds of the world have been depleted during the World War, who has learned how long it will be before they can be built up, will see in this condition an opportunity paralleled only in a small way by the noted investment opportunities of the past. About a hundred years ago the =railroad= offered an investment opportunity which the Vanderbilts were wise enough to see—and to seize. You know that the Vanderbilt wealth has lasted through generations—increasing year by year. About fifty years ago there was a similar opportunity offered in =steel=—demanded by the rapidly growing industries. The names of Carnegie and Schwab head the list of the famous “thousand steel millionaires”—made rich by foresight. Forty years ago =electricity= offered its opportunities to Edison—and to many others who have become extremely wealthy because they combined courage with foresight. Marvelous as have been the fortunes in =railroads=, in =steel= and in =electricity=, we are today, says the Luther Burbank Society in its book, “Give the Boy a Chance,” “facing an opportunity four hundred times bigger than the railroad opportunity was a hundred years ago, eight hundred times bigger than electricity offered at its inception, fifteen hundred times bigger than the steel opportunity which Mr. Carnegie found—=because agriculture is just by these amounts bigger than those other industries=.”
