The governmental experiment station ought to establish regular psychological laboratories, in which the mental processes involved in the farmer's activity would be examined with the same loyalty to modern science with which the chemical questions of the soil or the biological questions of the parasites are furthered. Only such investigations could give the right cues also to the manufacturers of farming implements. At present the machines are constructed with the single purpose of greatest physical usefulness, and the farmer who uses them has to adjust himself to them. The only human factor which enters into the construction so far has been a certain desire for comfort and ease of handling. But as soon as the mental facts involved are really examined, they ought to become decisive for the details of the machine. The handle which controls the lever, and every other part, must be placed so that the will finds the smallest possible resistance, so that one psychical impulse prepares the way for the next, and then a maximum of activity can be reached with the smallest possible psychophysical energy. Such a psychological department of the agricultural station could be expanded, and study not only the mental conditions of farming, but examine also the psychological factors which belong indirectly to the sphere of agricultural work. It may examine the mental effects which the various products of the farm stir up in the customers. The feelings and emotions, the volitions and ideas which are suggested by the vegetables and fruits, the animals and the flowers, are not without importance for the success in the market. The psychology of colour and taste, of smell and touch and form, may be useful knowledge for the scientific farmer, and even his methods of packing and preparing for the market, of displaying and advertising, may be greatly improved by contact with applied psychology.
