to do so. The increase of other important lines of work now 

 severely taxes the limited resources of this division, and renders 

 such a step necessary. 



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. O. money 

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

 Application may be made and money sent to

(b) Dairy Products and Feed Stuffs. 



Slightlj^ less than the usual number of samples of milk and 

 cream were received during the past year. They were sent 

 largely for the purpose of ascertaining their butter fat con- 

 tent. Some farmers wish to ascertain the quality of milk pro- 

 duced by their animals, while others who sell cream wish to 

 check the work of the local creamery. Oftentimes samples 

 are received from milk dealers whose product has been found 

 below the legal standard ; in such cases, both total solid 

 matter and fat are determined. Printed circulars are sent 

 to all inquiries, giving concise information concerning the 

 quality of milk produced by different breeds, as well as full 

 instruction relative to the best methods to be employed in 

 determining the butter-producing capacity of dairy herds. 



This division also examines milk, cream, butter and oleo- 

 margarine collected by the agent of the Dairy Bureau in 

 western Massachusetts. The past year the work has been 

 confined almost wholly to the examination of renovated 

 butter. The number of feed stuffs received was somewhat 

 in excess of those received a year ago. In some cases a 

 physical inspection only was necessary, while in other cases 

 both a chemical and microscopic examination are required. 

 Numerous samples are received from wholesale dealers, who 

 avail themselves of the station facilities to make sure that 

 the materials they are offering are as represented. It is the 

 intention to give such samples immediate attention, and to 

 return the results promptly.
