The blast attacks the flowers and very young fruit and is caused 
by the pycnidial form of Guignardia vaccinii. 
The term “scald” is applied to a disease of the cranberry which 
shows itself in the appearance of a minute, light colored watery 
spot upon its surface which rapidly spreads until the whole berry 
becomes soft. No definite fungus could be associated with this disease. 
The author then describes the life histories and developments 
of the Guignardia vaccinii and follows this by a discussion of the 
conditions or factors determining the productions of the ascogenous 
form, the dormant condition of the fungus, time and manner of 
infection and the treatment for the prevention of the development 
of this fungus. 
He then describes the decay of the cranberry usually called 
“rot” which he finds to be due to the recently described fungus 
Acanthorhynchns vaccinii. He gives a description of the various forms 
of this fungus, its cultural characteristics and methods to be adopted 
for its treatment. 
The anthracnose disease is one caused by Glomerella rufoma- 
culans vaccinii , whose cultural characteristics are described at length, 
together with methods to be adopted for treatment. 
The list of more important diseases is completed by a discussion 
of hypertrophy due to Exobasidium oxycocci. 
The Bulletin then discusses less important diseases of the cran¬ 
berry, together with extensive recommendations as to spraying 
methods which should be adopted. 
A bibliography dealing with cranberry diseases and sevenplates, 
two of them colored, complete the discussion. H. von Schrenk.

Sheldon, J. L., Concerning the Relationship of Phyllosticta 
solitaria to the Fruit Blotch of Apples. (Science XXVI. p. 183. 
1907.) 
The writer describes the cause of numerous Spots on leaves and 
fruits of the wild crab-apple, which also causes spots on the petioles 
and underside of the midribs of the leaves and of the fruits of the 
common apple. After a general discussion of apple spots caused by 
various fungi, he finds that the fruit blotch disease of apples is
