C. Character of Chemical Work. 

 {a) Water. 



In accordance with instructions from tlie experiment sta- 

 tion committee, a charge of tliree dollars has been made for 

 each sample of water examined by this department during 

 the past year. The reasons for this charge were explained 

 in a small circular sent to each applicant, a copy of which 

 was printed in the last report, page 50. Most applicants 

 have cheerfully paid the fee, while others have refused to 

 send the sample for examination because of the charge. The 

 number of samples examined has been 132, considerably less 

 than former!}^ ; but it is believed that the charge has resulted 

 in holding in check those who have heretofore sent from 4 

 to 20 samples annually, as well as those who have sent largely 

 out of curiosity, because an analysis could be had free of cost. 



Instructions for securing an analysis of water : — 



Those wishing to secure a sanitary analysis of water must first 

 apply, whereupon a glass bottle securely encased, accompanied 

 by full instructions for collecting and shipping the sample, will 

 be forwarded by express. The return expressage must in all cases 

 be prepaid. Because of the smallness of the sum involved, no 

 account will be opened. Remittance by check, P. 0. money 

 order, or money at the owner's risk, must be strictly in advance. 



Application may be made and money sent to 



Dr. J. B. LiNDSEY, 



Hatch Experiment Station. 



(b) Dairy Products and Feed Stuffs. 

 The number of samples of milk and cream sent largely 

 for the purpose of determining their butter fat content is 

 increasing from year to year. The increase in the number 

 of cream samples comes largely from creameries, w^hile the 

 milk comes from farmers desirous of ascertaining the quality 

 produced by the several animals in the herd. This latter is 

 a very satisfactory sign, and should meet with every encour-
