This is, indeed, as the writing of that ancient prophet of Israel who, in his vision of the restoration of his city and his land and the healing of its waters, saw a man with a radiant face, a line of flax in his hand and a measuring reed. And wherever this man of radiant face measured he caused the waters to run in dry places and deep rivers to course where the waters were but ankle-deep; fish to swarm again in the rivers and the seas to be free of pollution; salt to come in the miry places and trees to grow upon the land with unwithering leaves and abundant meat. So have these modern prophets with optimistic faces written of their vision, only the fulfilment comes not simply of the constructive measuring of statistics. It takes some trees a hundred years to grow; and dams and reservoirs for the deepening of shallow streams are not made over night as once they were by nature, or as they grew in the vision of Ezekiel. None the less is the prophecy a long way toward fulfilment when the vision is seen. And that it has been seen is intimated by this sentence, too optimistic no doubt, from a book on the subject by one of the major prophets of conservation, recently published in America. "Conservation," he says, "has captured the nation." It is not the thrifty, nepotic, static conservation of the St. Lawrence habitant, which depends upon the self and family interest of each landholder to keep the fields enriched and to prevent the washing away of the soil. It is a dynamic and paternalistic conservation--a conservation that thinks of great dams for the restraint of waters and reservoirs for their impounding to the extent of millions or billions of cubic feet, forestation of great stretches of mountain slope, of restrictions and compulsions of other than personal and family interests--a paternalism that looks beyond the next generation or even two generations and to the feeding of other children than one's own lineal descendants--a paternalism that is not exploiting but fiduciary. It is interesting to observe again how the beginnings of this conservation have been made in the fields where stood the first hospitals for the sick among the living, the first memorials to the dead, the first schools for the children of to-day that are to be the nation of to-morrow. Here also begin to rise the structures of the thought for the day after to-morrow.
