Memorize it! Just in time for the holidays:"Beechwood fires are bright and clearIf the logs are kept a year,Chestnut's only good they say,If for logs 'tis laid away.Make a fire of Elder tree,Death within your house will be;But ash new or ash old,Is fit for a queen with crown of goldBirch and fir logs burn too fastBlaze up bright and do not last,it is by the Irish saidHawthorn bakes the sweetest bread.Elm wood burns like churchyard mould,E'en the very flames are coldBut ash green or ash brownIs fit for a queen with golden crownPoplar gives a bitter smoke,Fills your eyes and makes you choke,Apple wood will scent your roomPear wood smells like flowers in bloomOaken logs, if dry and oldkeep away the winter's coldBut ash wet or ash drya king shall warm his slippers by."by Celia Congreve
