To remedy such evils, the trustees of all charities should hold out a regular scale of salaries, which different agents could attain to if they were successful. The principle, too, which should govern the amounts paid to each agent, should be well considered. Of course, the governing law for all salaries are the demand and supply for such services. But an agent for a charity, even as a missionary, sometimes puts himself voluntarily outside of such a law. He throws himself into a great moral and religious cause, and consumes his best powers in it, and unfits himself (it may be) for other employments. His own field may be too narrow to occasion much demand for his peculiar experience and talent from other sources. There comes then a certain moral obligation on the managers of the charity, not to take him at the cheapest rate for which they can secure his services, but to proportion his payment somewhat to what he would have been worth in other fields, and thus to hold out to him some of the inducements of ordinary life. The salary should be large enough to allow the agent and his family to live somewhat as those of corresponding ability and education do, and still to save something for old age or a time of need. Some benevolent associations have obtained this by a very wise arrangement--that of an "annuity insurance" of the life of their agents, which secured them a certain income at a given age. With the consciousness thus of an appreciation of their labors, and a payment somewhat in proportion to their value, and a permanent connection with their humane enterprise, the ordinary _employes_ and officials come to have somewhat of the interest in it which men take in selfish pursuits, and will exercise the inventiveness, economy, and energy that are shown in business enterprises. Every one knows how almost impossible it is for a charity to conduct, for instance, a branch of manufacture with profit. The explanation is that the lower motives are not applied to it. Selfishness is more alert and economical than benevolence. On the other side, however, it will not be best to let a charity become too much of a business. There must always be a certain generosity and compassion, a degree of freedom in management, which are not allowed in business undertakings. The agents must have heart as well as head. The moisture of compassion must not be dried up by too much discipline. Organization must not swallow up the soul. Routine may be carried so far as to make the aiding of misery the mere dry working of a machine. The thought must ever be kept in mind that each human being, however low, who is assisted, is a "power of endless life," with capacities and possibilities which cannot be measured or limited. And that one whose nature CHRIST has shared and for whom He lived and died, cannot be despised or treated as an animal or a machine.
