LETTER OF TRANSMITTAL. 



U. S. DEPARTMENT OF AGRICULTURE, 



BUREAU OF ANIMAL INDUSTRY, 



Washington, D. C., July %8, 

 SIR: I have the honor to transmit herewith revised copy of Farmers' 

 Bulletin No. 152, "Scabies of Cattle," by Richard W. Hickman, chief 

 of the Quarantine Division of this Bureau. This article was originally 

 printed as Bulletin No. 40, Bureau of Animal Industry, and after- 

 wurds, in April, 1902, as Farmers' Bulletin No. 152, of which 145,000 

 copies have been printed and distributed. The remedies herein given 

 for scabies, or mange, are those which have been tried and found most 

 efficacious by this Bureau. The results of the most recent experiments 

 are included in this revised edition of the bulletin, which, it is believed, 

 will add still more to its usefulness. 

 Very respectfully, 



D. E. SALMON, 



Chuf of Bureau. 

 Hon. JAMES WILSON, 



Secretary of Agriculture.
