Not of all persons will be required the same duty. What one is, that shall one give. Society will learn of every man and woman what these gifts may be. Some day it will be expected that every able person will report himself, at determined occasions, for definite service, without pay, in one or more of the following privileges, and other privileges, under orderly management and recognized public authority: 1. To clean up the earth and to keep it sweet,--streets, roads, paths, byways, vacant lots, stream banks, woods, fields, and all open, or public, properties and public works. The clean-up days now becoming popular are the beginnings. Of course this does not mean that the work of street-cleaning departments and the like is to be taken over or interfered with; but there are times for special house cleaning. If every person felt it devolving on him to help in keeping the earth decent, he would be likely to exercise a proper restraint in befouling it; and as charity begins at home, so should his restraint begin on his own premises, even extending to the parts out of sight of the public. 2. To take part in the construction of halls and premises for community activities. 3. To aid in the making of beautiful and public places accessible and to protect them. Every community with a rural environment, and practically every small city, has a near-by area that could be reserved and opened by coöperative action of the people,--days set aside when paths should be made, bridges built, retreats discovered, trees and streams put in shape, insects destroyed. Such reservations are not really public until the people volunteer to help in them. The farther places, the real backgrounds of the race, will some day be opened as well as reserved, and made of much use to very many people besides casual visitors and sight-seers. We shall learn how to project whole counties and cities, and even larger units, into the making and keeping of them in a way that is not yet visioned. This can be accomplished as easily as armies can be sent into the field, but it will require a type of organization at which we have not yet arrived. It will be worth while to develop public-service armies.
