MILK.

A NATION’S GREATEST ASSET. Milk is nature's most perfect food, providing all essential substances required for the. building of tissue, nerve, bone, muscle and intellect. But, if a perfect food for humans, it has been proved that it is also a perfect medium for the growth of harmful germs, and unless milk (or the product of milk) is of high hygienic quality it may become a menace lo life. Water, Nature’s Most Perfect Cleanser. if milk is Nature's most perfect food, so also is water Nature's most perfect cleanser, and the purity of milk can only be retained by the use of water, which is essentia] for cleaning every- j tiling with which milk comes in con- | tact, whether it lie human hands, buckets, milking machines, cream | separators, bottles, jugs, or other re- ! ceptacles and machines commonly used. But it is an indisputable fact that water will scour or cleanse only in accordance with the speed at which it which it is caused to flow. Water at a low rate of flow will not scour or cleanse, but, on the other hand, will deposit sediment on surfaces over which it passes—for example, take a sluggish creek-bed —whereas water flowing at a high rate of speed will remove anything adhering to surfaces over which it flows. To cleanse efficiently, it is necessary to use water at a high rale of llow, which applies essentially lo milking machines through which, in New Zealand alone, approximately 430,000,000 gallons of milk are passed annually, all of which, on an average, passes through 54 inches of rubber tubes and 30 feet of metal tubes of various diameters. Notwithstanding the above, the milking machine with proper facilities, proper atlention, and the judicious use of cold and boiling water, is by far l-he most hygienic method of obtaining milk from the cow and conveying it lo the receiving cans or separator. But one can readily imagine what can take place where proper facilities arc not provided arid made proper use of in the cleaning of every part of the milking machine.

The following particulars and llgures arc records of systematic practical tests with various makes of milking machines, and in each ease arc the nearest procurable average:— The Major Patent Teat-cup and Milk-tube Cleaner —(a) In bulbed part and recesses of teat cups scouring action: Old way, nil; the “Major” way, 20in per second; (b) On inner walls of inflations scouring action, bin per second; J.SOiu per second, (c) In rubber milk tubes and metal down tubes scouring action, Siiri per second; 108 in per second, (cl) Conditions of backs of inflations and inside air lubes, 75 per cent, wet; 100 per cent dryThe Major. Patent Millc-pipe Cleaner milk pipe (1 j -inch pipe: Old way, half full; the “Major” way, full behind cleaner (all sizes pipe). (f) Average length of milk pipe through which water does not pass, 10 inches; none, (g) Flow of water in main milk pipe (1 jin pipe), 7->in per second (bottom half only), ITOin over cleaner (all parts pipe), (h) Immersing leal cups in water to be drawn through the milk system did not improve the purity of water. Other factors in favour of the new system arc—t. in the event of power failing during the process of milking the milk system may be. flushed by attaching cleaning devices to water hose. 2, having of lime by cleaning teat cups and tubes both outside and in at the same lime. ;!. By the removal of all butter-fat and impurities Ihc life of nibbcrvva.ro is considerably lengthened, also minimises the risk of spreading infectious diseases through the herd. Better facilities for sterilising'all parts. The improved system has been put to severe tests by many leading dairyfarmers spread over a period of eight months, and alterations, improvements made to suit all makes of milking machines, and in every detail worked up to I lie highest possible stale of efficiency. The devices in question will be traded under the name of the Major Milking Machine Cleaners. Demonstrations will lie given at the Hamilton, Palmerston North, and Itawera Winter Shows, where dairy farmers and all interested in tiie dairying industry are cordially invited to investigate the claims made. Mr Thomas Sliiels, of Wanganui, Iho patentee and proprietor, lias been granted letters patent in all leading dairying countries, and is making Wanganui llie distributing cenlre. Demonslralions will lie given at all limes, in show room. Piiigan's now buildings, near Foster's Hol'd, Victoria Avenue, after May 25, and all inquiries addressed lo I’.ii, Box jis, Wanganui, will lie promptly attended 10. This device is being displayed al I In' Show by I lie palenlee in I In* main annexe, where dairy laelory managers, dairy inslriiclnrs, and all inleresled are invited to inspect.
