LETTER OF TRANSMITTAL. 



U. S. Department of AoRictrLTURE, 



Bureau of Plant Industry, 



Office of the Chief, 

 Washington, D. C, May 10, 1911. 



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

 ''Arrangement of Parts in the Cotton Plant," by Messrs. O. F. Cook, 

 bionomist, and Rowland M. Meade, scientific assistant, of this 

 bureau, and to recommend its publication as Bulletin No. 222 of the 

 bureau series. 



! Notwithstanding the great agricultural importance of the cotton 

 plant, its peculiarities have received very little study from the 

 botanical standpoint. This bulletin describes the general structure 

 and habits of the plant as affected by differences in the number, 

 position, and arrangement of the various parts. 

 Respectfully, 



Wm. a. Taylor, 

 Acting Chief of Bureau. 

 Hon. James Wilson, ^ 



Secretary of Agriculture.
