LETTER OF TRANSMITTAL 



U. S. Department of Agrictjlture, 



Division of Entomology, 

 Washington, D. C. , March 5, 190S. 

 Sib: I transmit herewith an article on silkworm culture, prepared 

 by Miss Henrietta Aiken Kelly, special agent in silk investigations of 

 this Division, and recently published as Bulletin No. 39 (new series) 

 of this Division, to which has been added a few paragraphs of infor- 

 mation on the culture of the mulberry, condensed from Bulletin No. 

 34 of the Bureau of Plant Industry. ' 



Miss Kelly has studied the culture of the mulberry silkworm as car- 

 ried on in France and Italy for a number of years, has consulted the 

 works of the best European authorities, and is therefore well qualified 

 for this task. Although the silkworm industry has not attained much 

 commercial importance in the United States, there is a popular demand 

 for information on the subject which, it is believed, can be supplied to 

 the best advantage by the republication of this matter in the popular 

 Farmers' Bulletin series. 



Respectfully, L. O. Howard, 



Entomologist. 

 Hon. James Wilson, 



Secretary of Agricyltwre,
