My self-imposed task is done. I undertook to tell What I Know of Farming through one brief essay for each week in 1870; and, in the face of multifarious and pressing duties, and in despite of a severe, protracted illness, the work has been prosecuted to completion. Had I not kept ahead of it while in health, there were weeks when I must have left it unaccomplished, as I was too ill to write or even stand. I close with the avowal of my joyful trust that these essays, slight and imperfect as they are, will incite thousands of young farmers to feel a loftier pride in their calling and take a livelier interest in its improvement, and that many will be induced by them to read abler and better works on Agriculture and the sciences which minister to its efficiency and impel its progress toward a perfection which few as yet have even faintly foreseen.
