 This bulletin contains brief references and reports upon about fifty plant

 absence of all scientific definition of the fungus causing the several 

 diseases, which are simply characterised by their common and popular 

 names.— M. G. C.

 Hort. May 1, 1905, pp. 211-215). — Reports of numerous experiments

 operation is effected by boring holes into the tree, inserting a powder or

 figures given, the results are often very striking. Several recipes are 

 given for the nutrients and remedies. — C. T. D.
