First published in 1911. According to the Preface: " Much has been said and written on the subject of conservation and many excellent ideas have been advanced, but as yet too little has been accomplished in the way of practical results. Probably this is due largely to the fact that most people think of conservation as a problem for the federal and state governments, mine owners, great lumber companies, owners of vast tracts of land, and large corporations; and have not realized how much the responsibility for the care of our natural resources and the penalty for their waste rest with the whole people, that every one has a part in this work which has been called "the greatest question before the American people."
