LETTER OF TRANSMITTAL 



U. S. Department of Agriculture, 



Office of Experiment Stations, 

 Washington, D. C , January 29, 1903. 



Sir: I have the honor to transmit herewith a bulletin prepared by 

 C. F. Langworthy, Ph. D., of the Office of Experiment Stations, which 

 summarizes and discusses the results of experiments on the feeding 

 and care of horses, and especially the investigations of recent years. 

 The attempt has been made to include all the work which has been 

 carried on at the experiment stations in the United States as well as 

 some of the more important foreign investigations. Statistics were also 

 gathered regarding the rations fed horses used by express companies, 

 cab companies, fire departments, packing houses, breweries, etc., in 

 diiferent regions of the United States, with a view to learning the nutri- 

 ents supplied to horses performing different amounts of work. The 

 data have been compared with similar values for horses fed at a num- 

 ber of the experiment stations under more or less definitely known 

 conditions. The rations fed army horses in this and other countries, 

 the horses of French and other cab companies, etc., have also been 

 included for purposes of comparison. 



Thanks are due to Director W. A. Heniy of the Wisconsin Station, 

 Director H. J. Patterson of the Maiyland Station, and Mr. G. M. Rom- 

 mel of the Bureau of Animal Industry of this Department, for valu- 

 able suggestions, and to Mr. H. A. Pratt of the Department of the 

 Interior, for assistance in making the calculations involved in preparing 

 the material. 



Believing that the bulletin will prove a useful summary of the infor- 

 mation at present available regarding the feeding of horses, I recom- 

 mend that it be published as Bulletin No. 125 of this Office. 



Respectfully, A. C. True, 



Dir'ector. 



Hon. James Wilson, 



Secretary of Agriculture.
