United States Department of Agriculture, 



Bureau of Chemistry, 



Washington^ D. C, December .9, 1901. 



Sir: I beg to transmit herewith the results of the work done in this 

 Bureau in the examination of the waters of the Hot Springs of Arkan- 

 sas. This work was undertaken in harmony with the request made to 

 you b} T the Secretary of the Interior, and under the instructions which 

 you gave me in acceding to that request. 



After a careful preliminary study of the nature of the problems to 

 be investigated, I, with your consent, detailed Mr. J. K. Haywood, one 

 of my assistants and an expert in water analysis, for the purpose of 

 undertaking the analyses desired. Mr. Haywood was given full instruc- 

 tions in regard to the character of the work which he was to perform, 

 and in compliance with those instructions proceeded to Hot Springs, 

 where he made the necessary study of the waters at the springs them- 

 selves. He also secured abundant samples of the waters for the 

 examination which could be made in the laboratory of this Bureau. 



Mr. Haywood has given in the following pages the results of his 

 investigations, together with certain opinions in regard to the thera- 

 peutic values of the waters, which it is deemed advisable should accom- 

 pany the report. In regard to these opinions it is only proper to say 

 that the}" are not our own, but are based upon the authorities which 

 are regarded as reliable in such matters. It must not be understood, 

 however, that these opinions in regard to the therapeutic value of the 

 waters have am T official indorsement whatever from this Bureau. We 

 have' not made any experimental determinations of the healing quali- 

 ties of the waters, nor have we studied their effects on invalids. These 

 opinions are subject to correction or change, in the light of further 

 investigations made by us or by other parties, and must not be accepted 

 with too much consideration. The value of these thermal waters in 

 certain chronic cases of disease is well established; but how this thera- 

 peutic action is secured is not a proper subject of investigation by this 

 Bureau.
