Eucalyptus cooling a fire <or smoke> is not a good idea as any fire fighter can tell you. Even fresh Euc will burn with a vengeance, there must be another reason for it. I can recommend also the dry cobs. Works wonderfully. The reducer I favor is Artemisia. Used by the ancient Egyptians and Tibetans, it can still be found in use by the cliff robbers in Nepal. It seems to calm the bees and produces a rich, slow smoke that seems to linger. It is abundant just about anywhere in the U.S. and Canada. Hessian bags are probably the best I've ever used in combination with Artemisia <Mugwort>. The mesh holds the herb suspended as it burns instead of allowing it to smother the spark. [log in to unmask]
