black birch

Here and there blackberries grew in the open places, sassafras bushes were plentiful, and black-birch bark was ready for chewing.

Henry said it was because they were poked with a black-birch stick.

The leaves of the sassafras are full of spice, and the bark of the black-birch twigs holds a fine cordial.

Yes, we actually have fig-paste, spicy with wintergreen and black-birch!
