8. The wood at the center of the tree is not as good as that just inside the sap wood. This characteristic is very common with nearly all the varieties of timber examined, especially so with the locust, the white cedar, the hardy catalpa, and the oaks. See Plates I and II. 9. The quality of the wood or the condition of the wood fiber of a post is a very important item in its ability to endure in the soil. In an average lot of so-called first class posts on the market, usually a number can be selected that are defective, though they may appear sound and firm. This quality of post is usually somewhat darker than the usual color, especially near the center of the tree. At the State Experiment Station at Wooster, Ohio, there are on file the data of every fence that was examined in this investigation. These data contain, among other items, the name and address of the owner, the location of the fence on the farm, and the date the fence was examined. Any one who feels inclined to examine any of these fences that happen to be in his community can get their location by writing to the Forestry Department of the Experiment Station. FOREST SERVICE.
