The last couple of days the stove in the barn has hardly used any coal, maybe 10 or 12 pounds every 24 hours. I was thinking "How can it stay lit using so little?" Well, it can't! I went out this morning to shake ashes & discovered an outfire. I don't know if I'll relight it or not. The next few days are supposed to be 15-20 at night & 35 during the day. Warm enough for sheep!
