As yet, the farmers have not risen to the full possibilities of motor power in economic superiority over horse power for haulage, ground cultivation, and other uses to which the horse is now put. Elements which will hasten this awakening are the scarcity of man labor and the workings of the immutable law of economics. There is not enough food being produced by the world to supply the demand. If there were, prices would be lower. Prices will remain high as long as the supply falls below the demand. As long as they remain high, the stimulation to greater production will continue, and this urge can have but one result, which is to force the producer to adopt the most economical method of production. It has been determined that motor power is cheaper than horse power. It is, therefore, only a question of time when the horse will go from the farm as he is disappearing from the cities. In this evolution will be found the money-making possibilities of investment in the motor tractor and the motor truck. Their adaptation to the smallest as well as the largest needs of the tiller of the land is now being assured. With the horse, the farmers of the United States have been able to break up only 70 per cent of the cultivable land not in timber. There are over two hundred million acres of tillable land that have never felt the cold steel of a chilled plow. There are two hundred million more acres in timber that will, much of it, ultimately come under the plow. Besides crippling the labor supply in this country, the European war has taken a million horses out of our supply. The case in favor of the tractor coming ultimately into common use seems from all this to be completely made out—its adoption in large numbers being only a question of getting the price down to a basis which will insure quantity production. As this was done with passenger automobiles, it would be folly to say it will not be done with tractors and trucks. Figures showing the total amount of money that has been taken in profits out of the automobile industry have never been compiled. It is a business that has developed so rapidly and feverishly that the water churned up by the commotion it has made has not yet settled. But there is a record of enough individual instances of gigantic profits to prove that the largest individual appetite for dividends should have been satisfied by the ratio of earnings already made in automobile manufacture. But in every case the greatest profits were in the stock of those companies that complied with Edison’s rule of large money-making—“What you want to do to make money is to make quantity.” And they were also companies which made an automobile that could be “‘et’ up,” as Armour put it, by time and use, in less time than it takes time and use to eat up a higher priced machine.
