Wood burners agree that oak and hickory are great firewoods.
If you have a wood stove or fireplace, it's prudent to know what types of wood will produce the most heat per cord (or rick, or truck-load, or whatever unit by which you buy wood!)A great chart is available at Firewood Ratings and Info. A short study of the chart reveals that oaks, hickory, white ash, and beech wood are some of the very best.
The Utah State Forestry also has an excellent firewood ratings chart with information about a somewhat different set of trees than would be found in my area (Kentucky). It gives high ratings to osage orange, pinon, honeylocust, and black locust, as well as oak and beech.
Compare those results with the following observations from about 130 years ago. It's interesting, but not surprising, that they liked oak, hickory, and white ash as firewoods. Beech didn't make their list, for some reason.
It is a great convenience to know the comparative value of different kinds of wood for fuel. Shellbark hickory is regarded as the highest standard of our forest trees, and calling that 100, other woods will compare with it for real value as fuel for house purposes as follows :
Shellbark Hickory, 100
Pignut Hickory, 95
White Oak, 84
White Ash, 77
Dogwood, 75
Scrub Oak, 73
White Hazel, 72
Apple Wood, 70
Red Oak, 67
White Beech, 65
Black Birch, 62
Yellow Oak, 60
Hard Maple, 59
White Elm, 58
Red Cedar, 56
Wild Cherry, 55
Yellow Pine, 54
Chestnut, 52
Yellow Poplar, 51
Butternut and White Birch, 43
White Pine, 30.
It is worth bearing in mind that in woods of the same species there is a great difference, according to the soil on which they grow. A tree that grows on a wet, low, rich ground will be less solid and, less durable for fuel, and therefore of less value than a tree of the same kind that grows on a dry and poor soil. To the ordinary purchaser oak is oak and pine is pine, but for home use, the tree grown on dry upland and standing apart from others, is worth a great deal more.

"The power to recognize trees at a glance without examining their leaves or flowers or fruit as they are seen, for example, from the car-window during a railroad journey, can only be acquired by studying them as they grow under all possible conditions over wide areas of territory. Such an attainment may not have much practical value, but once acquired it gives to the possessor a good deal of pleasure which is denied to less fortunate travelers."
