These should, like the Japan sorts, be planted twenty feet apart and should be treated in the same way. Under similar conditions they are not as vigorous growers as the Japs and, of course, do not need such radical treatment in pruning them. They are much more susceptible to the somewhat troublesome black knot, and everlasting and persistent watchfulness and eradication of this black fungus is the only sure way to success. The European class of varieties do not come into bearing as early as the Japans, neither are they as regular or prolific bearers; nevertheless it is a fine, handsome, high flavored fruit, in favor quite generally. Many large orchardists grow and fruit the best kinds largely for market purposes. When a judicious selection of varieties are properly cultivated and managed under favorable conditions, they always bring remunerative prices. We follow with a condensed descriptive list of the best varieties:
-- Early, dark violet red, juicy, sprightly. Tree vigorous, productive. Ripens middle of August.
* Yellow Egg
-- Large, oval, yellow, juicy, rich, vigorous, productive. Ripens during August.
* German Prune
-- Fruit oval in shape, nearly two inches long, of good quality and much esteemed; hangs on the tree, and is firm, sweet and pleasant. Ripens September 15th.
* Shropshire Damson
-- The flesh is amber colored, juicy and sprightly. Commands a high price; it is enormously productive. One of the most profitable plums we have. Ripens early in October.
* Imperial Gage
-- Rather large oval, greenish; flesh juicy, rich, delicious, a good grower. Ripens middle of August.
-- Medium, round, oval, violet, red, juicy, pleasant and good; adheres to the stone; productive. A valuable market variety. Ripens in August.
* Shipper's Pride
-- Large, round, purple; very firm, excellent quality. Very productive. A great market plum. Ripens in August and September.
-- All things considered, this is one of the finest and most popular plums. Fruit very large, roundish oval; skin yellow, with a slight crimson blush in well ripened specimens; flesh very sweet and luscious. Tree vigorous, with broad, handsome foliage; very productive. Ripens about September 1st.
* Green Gage
-- Small but of the highest excellence. Tree a moderate grower. Should be top grafted to get good trees. Ripens in September.
-- Tree a strong grower, with broad, rich, dark foliage; fruit large, yellowish-green, with marblings of deeper green, and a delicate white bloom; flesh pale yellow, very firm, sprightly, sugary and rich; fine for canning Ripens about August 20th.
-- Of extra large size and first rate flavor; color dark blue. Good bearer; not liable to rot. Ripens about August 1st. We regard it as one of the best new varieties.
* Moore's Artic
-- Size medium or below; skin purplish black, with a thin blue bloom; flesh greenish, yellow, juicy, sweet and of pleasant flavor. Charles Downing speaks of it as follows: "A new, hardy plum, which originated on the high lands of Aroostook county, Maine, where unprotected and exposed to cold, it has for many years borne enormous crops, and is claimed to be the hardiest plum grown. Tree healthy, vigorous; an early and abundant bearer." Valuable for market. Ripens in September.
* Fellenberg (French or Italian Prune).
-- A fine late Plum; oval; purple; flesh juicy and delicious; parts from stone; fine for drying. Tree a free grower and very productive. Ripens in September.
* Coe's Golden Drop
-- Large and handsome, oval; light yellow; flesh firm, rich and sweet; adheres to the stone. Tree a moderate grower and very productive. Valuable, not only on account of its large size and fine appearance, but its lateness. Ripens last of September.
* Wild Goose
-- An improved variety of the Chickasaw, evident in the great vigor of the tree and increased size of the fruit, which is nearly as large as the Green Gage. Skin purple, with a bloom; flesh juicy, sweet and adheres to the stone. Ripens last of July.
-- A fine variety; yellow, with a red cheek; flesh orange colored, juicy and rich; parts from the stone. Tree a slow grower, but productive. Ripens last of August.
* Yellow Gage
-- Fruit large, oval; skin golden yellow; flesh deep yellow, rich, sugary and melting. Tree very vigorous and productive. Ripens last of August.
