12 THE KANSAS CHERRY. 



From the dark Bigarreau the following are among the best types r 



Robert's Red Heart : Bright, dark red, with an under mottling ; as 

 large as Napoleon; flesh pinkish: juice nearly colorless, subacid; 

 heavy, regular bearer in Hudson river valley. Ripens with Napoleon. 



Mezel : Large, heart-shaped, obtuse, flattened at both sides; un- 

 even skin, dark red to black; firm, but heart-like; juicy; very sweet, 

 stem long and tortuous ; heavy bearer locally. Ripens with Napoleon. 



Windsor: Large, roundish-oblong, firm, juicy ; mottled dark red; 

 flesh pinkish white ; stem medium, set in a slight broad depression ;. 

 heavy bearer, vigorous, upright. Ripens two weeks after Napoleon. 

 Very profitable. 



Dikeman : Large, heart-shaped, obtuse, flattened on one side; 

 black, with extremely firm reddish flesh ; subacid, reddish juice ; stem 

 medium, in a slight broad depression : vigorous. Ripens three weeks 

 or more after Windsor. A variety of great value. 



DISEASES AND INSECTS. 



The brown rot {Monilia fructige?ia), vfhich. attacks the fruit at 

 the rij^ening period, and particularly during sultry weather, can be 

 largely avoided by picking the fruit a few days before ripe. It may 

 also fatally attack the flowers, leaves, and twigs. In localities where 

 the cherry blooms but does not fruit, the trees should be sprayed with 

 Bordeaux mixture before the buds unfold, again when the fruit is set, 

 and two or three times thereafter, with a colorless fungicide. 



Black-knot, { Ploinrightia morhosa Sacc.) [See elsewhere in this 

 book.] 



Leaf- blight {Cylindrosporiurn padi Karst). [See elsewhere in 

 this book.] 



Powdery mildew {Podosphoera oxycanthce De Bray). Often se- 

 vere in the sour cherry, but can be checked by thorough applications 

 of a fungicide. 



The aphis {Myzus cerasl Linn.) appears in the early part of the 

 season on the young shoots, the leaves, the stems, and less frequently 

 on the body or the fruit of the sweet cherries. It excretes honey-dew 

 abundantly. The leaves curl upward and inward. Spray with kero- 

 sene emulsion, one part to sixteen of water, or with fish-oil soap, one 

 pound to six gallons of water, before the leaves curl. 



The curculio {Conotrachelus nenuphar). [ See elsewhere in this 

 book.] 



Climatic injuries. — Sun-scald and bursting of the bark. The sweet 

 cherry is liable to a fatal injury from sun-scald in the South and 

 prairie states. The trouble occurs in the spring, when the rays of the 

 sun cause alternate freezing and thawing of the growing tissues on 

 the south and west sides. In these localities, the bark of the tree
