Despite the fact that Black Hawk was lauded by the horticulturists in the middle of the last century as one of the best of all black Sweet Cherries, it is now almost unknown. According to the older pomologists it was unsurpassed for eating out of hand but was only mediocre in all other characters of either fruit or tree. In particular it was surpassed in many ways by the better-known Eagle which fills about the same place in cherry culture. The variety was very popular in southern Ohio about Cincinnati where many trees may still be found and where it is still more or less planted. Possibly because of the excellent quality of the fruit, the amateur might well try a tree or two. The description is compiled. Black Hawk originated with Professor J. P. Kirtland of Cleveland, Ohio, sometime previous to 1845. It is one of the best of the many seedlings fruited by him. The American Pomological Society in 1854 named this sort as one of the promising new fruits and it still remains on the fruit-list of this organization. Tree large, vigorous, spreading, round-topped, resembling Yellow Spanish in habit, productive, healthy; branches stout, smooth, dark reddish-brown, straight; branchlets slender, with short internodes. Leaves large, folded upward, obovate, rather thick; upper surface dark green; lower surface pale green; apex abruptly pointed; margin coarsely and deeply serrate; petiole short, stout, bright red, with two or more orange-red, reniform glands. Buds of medium size, rather short, free; flowers small or medium in size; pedicels long, very slender; calyx-lobes straight, finely serrate, obtuse; petals roundish, broadly and deeply notched at the tip. Fruit matures about the middle of June, a few days later than Black Tartarian; medium to large, obtuse-cordate, surface uneven, sides compressed; cavity deep, broad, abrupt, nearly regular; color glossy, dark purplish-black changing to almost black at complete maturity; stem usually thick but often variable, of medium length; skin thick, adhering to the pulp; flesh purplish-black, tender, with abundant colored juice, aromatic, well flavored, sweet; of very good quality; stone of medium size, with uneven surfaces.
