LETTER OF TRANSMITTAL 



Maj. W. A. Graham, Commissioner. 



Sir :— I submit herewith manuscript for a Bulletin on "The Oyster- 

 shell Scale." Next to the San Jose Scale, this is the most important 

 scale-insect in the apple orchards of North Carolina, and the very con- 

 siderable number of complaints and inquiries which we receive regard- 

 ing it each year warrants the publication of a bulletin on the subject. 

 I recommend its publication as the June Bulletin for 1913. 



Very respectfully, 



Franklin Sherman, Jr., 



Entomologist. 

 Approved for printing, 



W. A. Graham, Commissioner.
