(c) Water Analysis. 

 Water from private supplies is analyzed by this section at $3 

 per sample, in order to determine its suitability for domestic 

 use. Analysis for mineral content, the bacterial examination 

 and the analyses of waters to determine their suitability for 

 boilers are not undertaken. Samples from public supplies are 

 not analyzed as all matters pertaining to public water supply 

 are by law placed under the direct charge of the State Depart-

 reserves the right to analyze only such samples as may be of 

 general interest, and will refuse to make analyses where the 

 samples are not properly taken or where such work is more prop-

 of milk and cream, human food stuffs will not be analyzed except 

 where they are direct products of Massachusetts agriculture.

 tests, while for the Holstein work twenty-two men have been 

 used at different times. During the latter part of the year the
