4. To demand the freedom of the earth for its inhabitants, under proper recognition of vested rights. The conception of the freedom of the sea has had an interesting evolution,--the escape from the old sea fear, the long years of piracy, the buccaneers, letters of marque and reprisal, treaty ports, smuggling, and all the rest; finally has come the demand of equal opportunities for all and the open door. We must have the open door to fields and shores, to commanding hills that should not be exclusive property; find trails and walks and avenues to places the people ought to know. All this requires exploration, tramps far and near, maps, propaganda. All scenic parts will be marked. The public shall know all good places. 5. To protect the products of the earth; and to protect the earth itself. The products to which I now refer are those not the property of individuals,--the birds, the beasts, the fish, the vegetation. The bird sanctuaries now so well accepted are good beginnings, as also the wild-flower preservation societies, the nature-study groups, and many others; but the individual is not yet sufficiently impressed with this feeling in his own action. To protect the earth is to save its fertility. This is the fundamental conservation. Not all persons can participate here, but every citizen can be mindful of the necessity of it and aid in creating public sentiment. I wait for the coming together of new organizations or societies that shall have for their purpose the conservation of fertility. These will be much more than agricultural and rural organizations, and their work need not be technical or occupational. They may include all persons, and the discussions and interests may run the range of man's relation to land. To leave his piece of earth more productive than when he took it is the obligation of the good farmer, for there are constantly more persons to be supported. In the large sense every one of us is a farmer, for the keeping of the earth is given to the human race. We begin to understand vaguely what relation the good keeping of the land bears to national questions. 6. To keep the public health,--to protect it by keeping one's body well, by taking care to commit no nuisance, to contaminate no source of public infection, and to lend one's self to participate in the correcting of abuses. To be physically fit and uncomplaining is a public duty. Maybe we shall find ways to demand physical training of the people as effective as that afforded by military training but without its sinister intentions.
