The sun is beginning to filter through the trees, and the dogwoods are in full bloom here on this beautiful spring morn at the John Oliver Place………….Split-rail fences require much more timber than other types of fences, and so are not common in areas where wood is scarce or expensive. However, they are very simple in their construction, and can be assembled with few tools even on hard or rocky ground. They also can be built without using any nails or other hardware; such hardware was often scarce in frontier locations…….American chestnut was the tree of choice until wire fencing became cheaper and the chestnut blight eliminated this tree…….. The distance between either the zigs or the zags was 16½ feet or one rod. A landowner could then count the zigs or the zags along the side and end of his field and determine the number of square rods in a field which in turn told him how many acres the field contained. One hundred sixty square rods is one acre, so a field ten rods times sixteen rods was an acre.
