84 EXPERIMENT STATION. [Jan. 



forwarding the samples. An analysis of water sent in 

 sliij^pers' jars will not be made, neither will bacteriological 

 nor mineral analyses be undertaken. 



The character of the samples received has been much the 

 same as that of those examined in previous years. They 

 were mostly from wells or springs, which frequently were 

 located in too close proximity to houses, barns and outbuild- 

 ings, and received the drainage. Samples are often found 

 contaminated with lead ; the station can only repeat its warn- 

 ing that all lead pipe be discarded, and replaced with iron 

 coated with asphaltum, or with galvanized-iron pipe. 



Dairy Peoducts and Cattle Eeeds. 



Farmers and dairymen continue to send samples of cream 

 and skim milk to be tested for butter fat, and samples of 

 whole milk to be tested for both solids and fat. More milk 

 is being sold for market purposes than formerly, and less 

 made into butter. The insi3ection of the quality of milk is 

 more general and rigid from year to year. Dairymen wish 

 to ascertain the composition of milk produced by individual 

 cows and by their herds, and likewise to confirm analyses 

 reported to them by the city milk inspectors and by con- 

 tractors. This work is performed gratis, and the results 

 reported promptly, together with such remarks and sugges- 

 tions as special cases call for. One creamery sends all of the 

 cream samples to be tested regularly, and others send occa- 

 sional lots when not in condition to perform the work. A 

 charge sufiicient to cover the cost is made in such cases. 



Samples of feeds (mostly concentrates) are received from 

 farmers, as well as from local grain dealers and jobbers. 

 The station willingly examines such material without charge, 

 when it seems that the conditions warrant it, and promptly 

 reports its findings mth suggestions when necessary. It 

 must be understood, however, that it cannot become the free 

 chemists of jobbers and manufacturers who wish to have 

 analyses made purely for commercial purposes.
