Narrative

Originated in Maryland and brought to Middletown, Kentucky by Captain William Chambers in 1800. Added to APS catalog list in 1875. Fruit fairly large in size, obovate-obtuse-pyriform, regular and symmetrical. Skin smooth, greenish-yellow in color, often blushed or striped with dull red. Flesh generally firm, crisp, granular, moderately juicy. Lacking in desirable flavor and texture characteristics. Early in season. Tree vigorous, upright-spreading in habit, dark green, abundant foliage, fairly productive. Fairly resistant to fire blight. -- H. Hartman 1957.

Originally the fruit was named 'Chambers.' The name 'Early Harvest' was given to the cultivar by Kentucky growers. - Anonymous

FRUIT: of medium size; form, obtuse, obovate, pyriform; color, pea green, turning yellow, when fully mature, with numerous brown and green dots, and reddish-brown cheek on sunny side; stalk, stout. 1 inch long, set on an ansle in a flat cavity, often one shoulder prominent; calyx, small, half- open; seeds, few. FLESH: white; texture, tender, fairly Juicy; flavor, aromatic, sweet and pleasant. QUALITY: good. VALUE: for near market first class. -- Fruits of Ontario, 1914.
