Though there should be organic connection between the school and business life, it is not meant that the school is to prepare the child for any particular business, but that there should be a natural connection of the everyday life of the child with the business environment about him, and that it is the affair of the school to clarify and liberalize this connection, to bring it to consciousness, not by introducing special studies, like commercial geography and arithmetic, but by keeping alive the ordinary bonds of relation. The subject of compound-business-partnership is probably not in many of the arithmetics nowadays, though it was there not a generation ago, for the makers of textbooks said that if they left out anything they could not sell their books. This compound-business-partnership originated as far back as the sixteenth century. The joint-stock company had not been invented, and as large commerce with the Indies and Americas grew up, it was necessary to have an accumulation of capital with which to handle it. One man said, “I will put in this amount of money for six months,” and another, “So much for two years,” and so on. Thus by joining together they got money enough to float their commercial enterprises. Naturally, then, “compound partnership” was taught in the schools. The joint-stock company was invented; compound partnership disappeared, but the problems relating to it stayed in the arithmetics for two hundred years. They were kept after they had ceased to have practical utility, for the sake of mental discipline—they were “such hard problems, you know.” A great deal of what is now in the arithmetics under the head of percentage is of the same nature. Children of twelve and thirteen years of age go through gain and loss calculations, and various forms of bank discount so complicated that the bankers long ago dispensed with them. And when it is pointed out that business is not done this way, we hear again of “mental discipline.” And yet there are plenty of real connections between the experience of children and business conditions which need to be utilized and illuminated. The child should study his commercial arithmetic and geography, not as isolated things by themselves, but in their reference to his social environment. The youth needs to become acquainted with the bank as a factor in modern life, with what it does, and how it does it; and then relevant arithmetical processes would have some meaning—quite in contradistinction to the time-absorbing and mind-killing examples in percentage, partial payments, etc., found in all our arithmetics.
