Very effective co-operation has continued to be maintained with the
Office of Forest Pathology, of the U. S. Bureau of Plant Industry.
Recently the salaries of all pathologists connected with the Commission
have been carried by that office, and there has been constant
communication and co-operation in reference to all research work.
Much excellent help has continually been given by the State Forestry
Department at Harrisburg, the Deputy Commissioner, Hon. I. C. Williams,
being assigned as a collaborator with this Commission.
The authorities of the University of Pennsylvania have been exceedingly
courteous in granting ample space for laboratory work in the new
Zoology Building. Room has also been given for laboratory work in tree
medication in the Botanical Building. Franklin and Marshall College, at
Lancaster, and the State College of Pennsylvania, have also provided
room for laboratory work in the field investigations.
There has been a liberal interchange of ideas and helpful suggestions
through correspondence with the State Conservation Commission at
Albany, N. Y., the State Forester and State Pathologist of New Jersey,
the State Forester of Maryland and of Massachusetts, and with officials
in Virginia, West Virginia, and Maryland.
