Institute, Feb. 6, 1872 ; by Charles H. Peck, A-M.—A large partof 
this Report is devoted to an elucidation of the cause and cure of 
“black knot in cherry and plum trees. Mr. Peck concludes the 
disease to be of fungoid nature, having the dual form of Cladospo- 
rium and Spheria. A highly interesting account of our new Ar — 
ceuthobium is given, from which we quote : “We infer that the 
’ history of the plant is as follows: The fruit being mature in es 
tember, some bird or other small- animal seeks it for food. The 
seeds being covered with a very viscid coat, adhere more or less to 
the beak.of the bird or the mouth of the animal, and being a soureé 
of annoyance to it, they are rubbed off from time to time on the © 
branch. Those that adhere through the winter to the young and_ 
tender shoot of the past season, germinate and form, during the — 
first summer, the little hemispherical buds above mentioned. Dur- 
ing their second season these increase in stature and form ther — 
flower buds. Probably early in the following season, the thirdin the 
life of the plant, the flowersexpand, and by the middle of September _ 
the fruit is mature.” We are sorry to see that Mr. Peck and Mr 
Wood have been in haste to name this plant while Dr. Engelman, 
to whom the subject properly belongs, is engaged in unravelling the — 
difficult relations of the species——3. A beautiful colored plate of —
