I am sharing this campfire to warm up all my cold friends! It was very cold this day when I burned the big tree that had to be cut down. I was glad to be close to the warmth for awhile. As you know, when you gaze into a fire, your mind tends to wander. I was thinking about how long people have been cooking with fire. (Of course, I looked it up in Google Search). Turns out people have been cooking with fire longer than humans have been on Earth! Like hundreds of thousands of years longer. So who was cooking? The monkeys? No other known species has ever used fire. That's why I have decided to let somebody else figure out this 'fire news' and tell me later. I have shared an excerpt from Wikipedia on Fire. Maybe it will light a spark on some of You to find out a little more for yourself!
Your photostudy is from this afternoon, when finally the sun broke through and the buzzards got busy drying their feathers. Enjoy!

- turning off the gas supply, which removes the fuel source;
- covering the flame completely, which smothers the flame as the combustion both uses the available oxidizer (the oxygen in the air) and displaces it from the area around the flame with CO2;
- application of water, which removes heat from the fire faster than the fire can produce it (similarly, blowing hard on a flame will displace the heat of the currently burning gas from its fuel source, to the same end), or
- application of a retardant chemical such as Halon to the flame, which retards the chemical reaction itself until the rate of combustion is too slow to maintain the chain reaction.
