(c) Milh, Cream and Feeds sent for Free Examinaiion. 

 The experiment station has in the past analyzed and will 

 eontinne in the future to analyze samples of milk, cream and 

 feeds sent for examination, in so far as the time and resources 

 at its command will allow. Only in exceptional cases should 

 material intended for free chemical examination be sent to the 

 experiment station, except by previous arrangement. Upon 

 application full instructions for sampling and directions for 

 shipping will be furnished. 



{d) Sanitary 'Analysis of Drinhing Water. 



During the year ending Dec. 1, 1908, there have been ex- 

 amined 143 samples of water. The cost of an analysis is $3, 

 which must be forwarded in advance and the express charges 

 on the sample prepaid. In order to secure an analysis, appli- 

 cation must be made, whereupon a suitably encased glass jar, 

 together with full instructions for gathering and shipping, are 

 forwarded by express. An analysis of water sent in shipper's 

 jar will not be made, neither will a bacteriological nor mineral 

 analysis be undertaken. The station does not examine water 

 to determine its fitness for manufacturing jDurposes, it being 

 held that this is the legitimate work of the commercial chemist. 

 The object of the station in making an examination of water 

 is to enable citizens of the State depending upon wells and 

 springs to ascertain, at a minimum expense, whether their 

 supply is free from objectionable matter, which is likely to 

 gain access to it from sinlv, privy or barn drainage. Such an 

 examination is referred to as a sanitary analysis. Those who 

 are dependent upon local wells and springs are frequently very 

 careless in the care of the same. As a result the water becomes 

 jDolluted, and serious sickness is likely to follow. After the 

 soil has once become contaminated it requires considerable 

 time to f)urify itself, and the water is often rendered unfit for 

 use for a number of years. Farmers and others are strongly 

 urged to guard the well and spring from all possible bad drain- 

 age. Sink drainage should be conducted at least 100 feet or 

 more away from the well and properly cared for, privy vaults 

 should be located a similar distance and be frequently cleaned
