LETTER OF TRANSMITTAL. 



U. S. Department of Agriculture, 



Bureau of Plant Industry, 



Office of the Chief, 

 Washington, D. C, September 24, 1909. 

 Sir: I have the honor to transmit herewith a paper entitled "The 

 Mistletoe Pest in the Southwest, " by Prof. William L. Bray, formerly 

 a special agent in the Office of Investigations in Forest Pathology. 

 The paper embodies the results of several years of investigation 

 of the various phases of the mistletoe pest and an account of the meth- 

 ods of combating it that are known at present. The subject of con- 

 trol of the mistletoe pest is still under investigation in this Bureau. 

 This paper, however, marks the completion of Professor Brays work 

 on the subject. I recommend that it be published as Bulletin Xo. 

 166 of the special series of this Bureau. 

 Respectfully, 



A. F. Woods, 

 Acting Chief of Bureau. 

 Hon. James Wilson, 



Secretar-y of Agriculture.
