Rockport is of very doubtful commercial value and has too many faults to be included with the best sweet sorts for a home orchard. It is more easily characterized by its faults than its merits. Compared with the well-known Yellow Spanish, of which it is a seedling and to which it is similar, the cherries are smaller and the pits are larger than those of the parent variety,—quite too large for the amount of pulp. Worst of the faults of the variety is, however, that the cherries are not sufficiently firm of flesh to withstand harvesting, shipping and the attacks of the brown-rot fungus. To offset the defects of the fruit the flesh is rich, sweet and tender, making it, all in all, as good as any other Sweet Cherry for dessert. The trees, too, are very satisfactory, being large, vigorous and very fruitful, though with the reputation of requiring good soil and the best of care, of lacking a little in hardiness to cold, and of having the period of maturing the crop more or less changed by soil and culture. Rockport has been, and is, more or less popular in New York but it can be recommended only for a home orchard.
Rockport is another of Professor Kirtland's introductions, having been raised by him at Cleveland, Ohio, about 1842, from a seed of Yellow Spanish. It soon won a place, in 1862, on the fruit list of the American Pomological Society where it still remains. It is mentioned by several foreign authors and many American nurserymen offer it for sale. Swedish is given as a synonym of Rockport by Hooper.
ROCKPORT
Tree large, vigorous, upright, very productive; trunk somewhat slender, roughish; branches smooth, reddish-brown, with numerous small lenticels; branchlets stout, variable in length, with long internodes, brown almost entirely overspread with ash-gray, smooth, with conspicuous, raised lenticels.
Leaves numerous, three and one-half inches long, one and three-fourths inches wide, folded upward, long-oval to obovate; upper surface dark green, somewhat rugose; lower surface dull, light green, pubescent along the veins; apex acute to taper-pointed, base abrupt; margin coarsely serrate, glandular; petiole two inches long, tinged with red, with a few hairs on the upper surface, glandless or with from one to four large, reniform, reddish glands variable in position.
Buds large, long, pointed, plump, free, arranged singly and in clusters from lateral buds and short spurs; leaf-scars prominent; season of bloom intermediate; flowers white, one and one-fourth inches across; borne in clusters usually in twos; pedicels one inch long, glabrous, greenish; calyx-tube green, campanulate, glabrous; calyx-lobes acute, glabrous within and without, reflexed; petals roundish, entire, dentate at the apex, nearly sessile; filaments nearly one-half inch long; pistil glabrous, shorter than the stamens, often defective.
Fruit matures early; one inch in diameter, cordate to conical, compressed; cavity shallow, wide, flaring, regular; suture a distinct line; apex roundish, with a small depression at the center; color bright red over an amber-yellow background, mottled; dots very numerous, small, light yellowish, somewhat conspicuous; stem one and one-half inches long, adhering well to the fruit; skin thin, tender; flesh pale yellowish-white, with colorless juice, tender, somewhat melting, aromatic, mild, sweet; good to very good in quality; stone free, ovate, plump, with smooth surfaces.

Royal Duke has a place in the cherry flora to follow in season the well-known May Duke and to precede another standard sort, Late Duke. It is so nearly like these two sorts, except in season, and so similar to Arch Duke, as well, that there is much difficulty in getting the variety true to name. It is more often taken for May Duke than for the other kinds named but it differs from this well-known sort in being a little later in season, and the cherries are larger, a little lighter in color, do not hang as thickly, being scattered along the branches, often singly, and are more oblate. The trees are markedly upright and the foliage is very dense. None of the Dukes are popular in America for market fruits and this is no exception though, among all, Royal Duke is as good as any—pleasantly flavored, juicy, refreshing and very good. The trees, too, are very satisfactory. The variety has a place in home orchards and for local markets. The French say that the tree makes a very weak growth budded on the Mahaleb and that it should be worked on the Mazzard, which is generally true of all Dukes. The buyer will have difficulty in getting the true Royal Duke in America.
The origin of this variety is unknown but the Royale d'Angleterre, mentioned by Christ in 1791, was probably the variety now known as Royal Duke, although the description is too meager to be certain. According to Thompson, Royal Duke was one of the varieties formerly cultivated in England under the names Late Duke, Arch Duke, or Late Arch Duke and was probably introduced by the London Horticultural Society from France under the name of Anglaise Tardive. When or by whom this variety was introduced into America is not known but according to Downing it was very rarely found here in the first half of the Nineteenth Century. The American Pomological Society placed Royal Duke upon its catalog list of recommended fruits in 1871.
