A colleague of my wife offered the wood from a tree he had dropped in his yard. I went over today to check it out and not knowing all that much about it I started splitting. Some of the rounds are in the 4 foot diameter range and are really hard to deal with. I intended on renting a splitter but figuring the cost and the amount of wood I'm not sure it's worth it. I would say it was around two cords and it turns out it is most likely silver maple. When i got to the house his wife told me it was a beech tree but I didn't think so so I brought a piece home to see if I could identify it. I'm going by the bark and the best match I could find was the silver maple. It doesn't rate all that well on the btu charts but I figured I would ask if anyone had any experience burning it? Thanks.
