ai'6 consumed aiinually along with the milk. Milk hxmx a 

 healthy cow m certainly at the outset free irom dirt. The 

 dust floating: in the air, lying on the bam floor, mixed 

 ^\'ith the haj/, or concealed by the hairy slan ot the cow, fur- 

 nishes a large proportion of the. dirt, even in somewhat 

 carefully handled milk. When less care is, taken ax^tual' 

 refuse dn visible masses can be seen as a, sediment in the 

 bottom of the can or bottle. 



Let lis, therefore, reier to certain features in daivj- 

 hyg-iene, which fonn the basis of all rules and regtdations' 

 in city by-law's or otherwiso for the control of clean milk^, 

 I taJce the libei-ty of quoting in part from the Canadian 

 Medical Milk Commission's report: 



1. The barnyai'd should be free from manure and well 

 drained, eo that it may be free from st-agnant wat^r. Ob- 

 servance of these rules frees the ba:rnyard of objectionable 

 ismells and diminishes the number of flies. These flies are 

 an element of danger, being fond of both filth and milk, 

 and are liable to get into the milk aiter having soiled their 

 bodies and legs in recently visited filth, thus carrying it 

 into the milk. 



The stables should be v\'eli ventilated and lighted. 

 Rome authorities, require at least four square feet of wm- 

 dow .glass, and at least 500 cubic feet of air space for each 

 animal. The ceilings s-hoiild be tight and the floor s;XTiitary 

 and preferably of cement. . The manure sliould be removed 

 from the stalls at least twice daily. All sweeping and clean- 

 ing should be finished at least one hour before milking, so 

 that at that time, especially, tlie air s-hould be free froni 

 ■ dust. 



The importance of perfectly clean, pure wat-er has 

 been generally recognized by all, both for drinking and for 

 isanitary purposes. It should also^ be abundant at all sea- 

 sons, suflieient for personal cleanliness, for the laundry, 

 for washing utensils, and for the premises generally. Con- 

 venience of the supply is a consideration v/hich should re- 

 £jeiv^. attention. If thia water should bA.ve tp> be bauled bv
