On what we call “rolling,” or hilly land, I would put the heap on the highest land, so that in the spring the horses would be going down hill with the full carts or wagons. Of course, it would be very unwise to adopt this plan if the manure was not drawn from the yards until spring, when the land was soft; but I am now speaking of drawing out the manure in the winter, when there is sleighing, or when the ground is frozen. No farmer will object to a little extra labor for the teams in the winter, if it will save work and time in the spring. [Illustration: _Field, 40×20 Rods, showing Position of two Heaps of Manure, a, a._] If the land is level, then the heap or heaps should be placed where the least distance will have to be traveled in drawing the manure from the heap to the land. If there is only one heap, the best point would be in the center of the field. If two heaps, and the field is longer than it is broad, say 20 rods wide, and 40 rods long, then the heaps should be made as shown on the previous page. If the field is square, say 40 × 40 rods, and we can have four heaps of manure, then, other things being equal, the best points for the heaps are shown in the annexed figure: [Illustration: _Field, 40×40 Rods, showing Position of four Heaps of Manure, a, a, a, a._] Having determined where to make the heaps, the next question is in regard to size. We make one about 8 feet wide and 6 feet high, the length being determined by the quantity of the manure we have to draw. In cold weather, it is well to finish the heap each day as far as you go, so that the sloping side at the end of the heap will not be frozen during the night. Build up the sides square, so that the top of the heap shall be as broad as the bottom. You will have to see that this is done, for the average farm-man, if left to himself, will certainly narrow up the heap like the roof of a house. The reason he does this is that he throws the manure from the load into the center of the heap, and he can not build up the sides straight and square without getting on to the heap occasionally, and placing a layer round the outsides. He should be instructed, too, to break up the lumps, and mix the manure, working it over until it is loose and fine. It there are any frozen masses of manure, place them on the east or south outside, and not in the middle of the heap. If there is any manure in the sheds, or basements, or cellars, or pig-pens, clean it out, and draw it at once to the pile in the field, and mix it with the manure you are drawing from the heap in the yard.
