the others, and with many the more influential, being desire of power, of social position, and reputation for ability and success. So you see that though we have abolished poverty and the fear of it, and inordinate luxury with the hope of it, we have not touched the greater part of the motives which underlay the love of money in former times, or any of those which prompted the supremer sorts of effort. The coarser motives, which no longer move us, have been replaced by higher motives wholly unknown to the mere wage earners of your age. Now that industry of whatever sort is no longer self-service, but service of the nation, patriotism, passion for humanity, impel the worker as in your day they did the soldier. The army of industry is an army, not alone by virtue of its perfect organization, but by reason also of the ardor of self-devotion which animates its members. But as you used to supplement the motives of patriotism with the love of glory, in order to stimulate the valor of your soldiers, so do we. Based as our industrial system is on the principle of requiring the same unit of effort from every man, that is, the best he can do, you will see that the means by which we spur the workers to do their best must be a very essential part of our scheme.

Compared with the effect of our social arrangements in impelling men to be zealous in business, we deem the object-lessons of biting poverty and wanton luxury on which you depended a device as weak and uncertain as it was barbaric. The lust of honor even in your sordid day notoriously impelled men to more desperate effort than the love of money could.« »I should be extremely interested,« I said, »to learn something of what these social arrangements are.« »The scheme in its details,« replied the doctor, »is of course very elaborate, for it underlies the entire organization of our industrial army; but a few words will give you a general idea of it.« At this moment our talk was charmingly interrupted by the emergence upon the aerial platform where we sat of Edith Leete. She was dressed for the street, and had come to speak to her father about some commission she was to do for him. »By the way, Edith,« he exclaimed, as she
