PURE MILK METHODS

FROM COW TO CONSUMER NO CONTACT WITH AIR. NEW YORK, October 12. It is now possible for milk to mako tho entire journey from cow to consumer without contact with tho air until opened for use. Barnyard milking has given place to dairy science Now comes Mr 11. R. Graves, who is in charge of dairy cattle feeding, breeding, "and management investigations for tho bureau of dairy industry, controlled by the United States Department of Agriculture, with an idea that may set a new pinnacle of dairy sanitation. Installed on an experimental farm, Mr Graves’s method consists of overhead sanitary pipe lines that carry milk direct from the cow to large vacuum tanks in the dairy house, it can be cooled as it enters tho tank, or it can be pasteurised and then cooled in the same tank. It is possible, lie says, to go a step further and bottle tho milk under vacuum, using the principles now commonly employed in canning fruits and vegetables. The system consists of a mechanical mi Iking unit of standard make, but instead of going into the usual portable receptacle tho milk is drawn into a stationary container located between two stalls and somewhat above tho cows. The receptacle is of unbreakable glass, and is suspended from a weighing mechanism. Its transparency makes tho rate of milking visible to the operator at all times, both by tho amount of milk in the receptacle and by tho weight registered by the scale. When the milk ceases to flow into tho receptacle the operator records the weight of tho milking and opens a valve, which permits the milk to l>e drawn from tho bottom or the container through the pijm lines. The system not only gives a cleaner product, Mr Graves says, but reduces the labour and the costs incidental to milking.
