Finally, we begin to enter the productive stage, whereby we secure supplies by controlling the conditions under which they grow, wasting little, harming not. Farming has been very much a mining process, the utilizing of fertility easily at hand and the moving-on to lands unspoiled of quick potash and nitrogen. Now it begins to be really productive and constructive, with a range of responsible and permanent morals. We rear the domestic animals with precision. We raise crops, when we will, almost to a nicety. We plant fish in lakes and streams to some extent but chiefly to provide more game rather than more human food, for in this range we are yet mostly in the collecting or hunter stage. If the older stages were strongly expressed in the character of the people, so will this new stage be expressed; and so is it that we are escaping the primitive and should be coming into a new character. We shall find our rootage in the soil. This new character, this clearer sense of relationship with the earth, should express itself in all the people and not exclusively in farming people and their like. It should be a popular character--or a national character if we would limit the discussion to one people--and not a class character. Now, here lies a difficulty and here is a reason for writing this book: the population of the earth is increasing, the relative population of farmers is decreasing, people are herding in cities, we have a city mind, and relatively fewer people are brought into touch with the earth in any real way. So is it incumbent on us to take special pains--now that we see the new time--that all the people, or as many of them as possible, shall have contact with the earth and that the earth righteousness shall be abundantly taught. I hasten to say that I am not thinking of any back-to-the-farm movement to bring about the results we seek. Necessarily, the proportion of farmers will decrease. Not so many are needed, relatively, to produce the requisite supplies from the earth. Agriculture makes a great contribution to human progress by releasing men for the manufactures and the trades. In proportion as the ratio of farmers decreases is it important that we provide them the best of opportunities and encouragement: they must be better and better men. And if we are to secure our moral connection with the planet to a large extent through them, we can see that they bear a relation to society in general that we have overlooked. Even the farming itself is changing radically in character. It ceases to be an occupation to gain sustenance and becomes a business. We apply to it the general attitudes of commerce. We must be alert to see that it does not lose its capacity for spiritual contact.
