A Scientific American "Ask an Expert" online response:http://www.sciam.com/askexpert_question.cfm?articleID013084-5B3B-1C72-9EB7809EC588F2D7&catID=3&topicID=4
The author also uses a 'burning log' as an example!

To quote part of their answer...
"Those that require heat to occur are described as endothermic, and those
that release heat as exothermic."
Done.  Filed.  Now I can move on.
Thanks Dan.

Noting that this is only a partial answer, it is not accurate.
Actually, any reaction that requires heat has an energy of activation.  If 
the system has less energy than when it started (gives off energy/heat), 
then it is exothermic; if the system has more energy (retains the energy), 
then it is endothermic.
You may move on now
