Notwithstanding the teachings of many excellent persons that stable manure is the most costly of all fertilizers, it is to-day the most popular of all. Possibly it is one of those cases in which incidental advantages outweigh direct ones - in popular parlance, a case where the "longest way round is the shortest way there." Horses and men are often in need of something to do, and they can be put to work at manure hauling when there is nothing else needed. Again, the lightening of the soil by the decay of vegetable matter is a gain. In short, the value of manure is not wholly a question of chemistry.
