There would be some force in the objections made against hard botanical names, if those who prefer common ones would properly identify the plants they mean. The Scientific American gives us the following. By "black dogwood, or berry-bearing alder," we suppose Prinos verticillata is meant, but surely that does not make wood large enough for extensive charcoal uses:

"The black dogwood or the berry-bearing alder makes the best charcoal, willow is next, and the common alder third in rank. Small wood of about ten years growth is in all cases to be preferred for charcoal for making gunpowder. Alder and willow at this age will be probably 4 or 5 inches in diameter, dogwood about 1 inch."
