242 Report of the Acting Director and Chemist of the 



would do nobody any good. Others are entirely foreign to agricul- 

 tural interests and often of a purely private commercial character. 



In order that there may be a clear understanding in regard to this 

 matter, the Board of Control has considered it necessary to make 

 the following rules . 



Rule I. — Chemical work that does not relate directly to agricul- 

 tural matters can not he undertaken at all. 



Ride II. — Before sending to the Station samples of anything 

 for analysis, private parties should first state the nature of the 

 work they vnsh to have done and the reasons for having it done. 

 Information can then be given as to the advisability of doing the 

 work. All such work, if done at all, is done gratuitously, and the 

 Station must, in every case, decide whether the importance of the 

 work is sufficient to justify the expenditure of time and materials 

 that may be required. Undoubtedly, many who ask the Station to 

 make gratuitous analyses for them do not fully understand the large 

 amount of time a satisfactory analysis of almost any substance re- 

 quires and do not realize to what extent compliance with their 

 wishes would interfere with our i-egular work. 



Rule III. — In deciding what chemical work it can or can not 

 do, the Station always plans to consult the henefit of the greatest 

 number. Preference will always be given to the work promising 

 information that is for the benefit of the larger number of individ- 

 uals. 



Rule IV. — Any chemical work which is for private commercial 

 interests can not he undertaken. Such work properly belongs to a 

 private professional analyist, and the State should not be asked to 

 do such work. 



Rale V. — A complete analysis of any soil or mineral can not be 

 undertaken except in rare cases. Analysis of water must generally 

 be regarded as foreign to our work. Analysis in suspected cases of 

 poisoning, adulteration of drugs, etc., can not be undertaken here. 



Ride VI — The determination of fat in milk will be undertaken 

 at any time. In such cases the milk should be sent to the Station as 

 quickly as possible ; a small amount of potassium bichromate may 

 be added as a preservative. An examination of foods for animals
