APPLES AFFECTED WITH BITTER-ROT. 
Fic. 1.—An apple affected with bitter-rot and, just above it, a mummied apple of the 
preceding season. Spores washed down from the mummy have infected the pre- 
viously sound apple. Variety, Yellow Newtown, Greenwood, Va., 1916. 
Fic. 2.—Apples with the ‘‘peppered’’ appearance caused by many infections. These 
small blisterlike spots were due to infection by spores coming directly from a bitter- 
rot canker. Variety, Missouri. Bentonville, Ark., 1914.
