AUCTIONS. H. MATSON AND CO. Extract—JOUßNAL OF AGRICULTURE, VICTORIA. March, 193 d. THE CLEANING OF MILKING MACHINES. By A. J. Gill, Senior Herd Teiter. Milking machines, perhaps mort; than anv other dairy equipment, re-j quire thorough cleansing. In careful hands machines give excellent results, but if subjected to careless and improper treatment they become a menace in the production of milk and cream. The over enthusiastic salesman may be responsible, to some extent, for the i'alse impression that the washing or anv particular type of machine is a very simple matter. All that is lequired, he may claim, is the sucking of a little water through the system after the milking has been completed. Purchasers of milking plants must understand that this is not sufficient, and that efficient and satisfactory results ■will be obtained only by careful handling, thorough washing, cleansing, and (sterilising of the entire machine units. On all dairy farms, whether machines are used or not, it is essential that there should be some satisfactory appliance for heating water, the ideal being a steam boiler or other system from which steam can be obtained tinder pressure. Other necessary appointments consist of a plentiful supply of washing or caustic sof'a. brushes, and a trough large enough to allow the immersion of the utensils. If a steam jet is not used, then another trough ■will be required to hold a supply of boiling water. All utensils which come in contact •with milk or 'Cream become greasy. 33y the use of soda and boiling water the fat is acted on in such a way that its complete removal is a comparatively easy matter. Soda, too, has certain antiseptic properties, but it must be remembered that it cannot take the place of boiling water. j Dairy farmers need not look past j 1 LUCERNE for a fodder to in- ! 1 crease stock-carrying capacities. | I Buy Marlborough or Hunter River j seed from Matson's. Caustic soda is more powerful in its action than washing soda, and the use of too strong a solution must be guarded against—two tablespoonfuls uf the caustic form to one kerosene tin (four gallons of water, or one des-eert-spooniul to one gallon; is'sufficiently strong. Care must be taken to prevent the solution from lodging in the milk-ho.V;ing vat, nor should the solution be allowed to stay in contact with the utensils for any length of time. After washing in soda solution, all materials should be rinsed with boiling water, as the least trace of solution will have a i.iost harmful effect on milk or cream with which it may come in contact. The udders and teats of all milking cows should be washed carefully with a clean cloth and clean water, after which the milk from each teat should be examined carefully for any trace of mastitis. If present and not discovered, this disease can be transmitted rapidly to other cows in the herd by means of the teat cups. A diseased cow must not be milked by machines. j SCOTCH TARES—A fine fodder ] I for milking Cows. Seed can be ' i had from— j i H. MATSON and CO. I The operator must be careful with bis personal cleanliness, and be alert at all times in case a .unit should fall from the udder. If this does occur the suction should be stopped immediately, and the teat cups washed in clean, warm water before they are returned to the udder. If this practice is not adopted it is possible that all the milk from that milking will be contaminated seriously from the floor dirt adhering to the teat cups. Manure should never be left, even temporarily on a cowshed floor where machines are in use, this being a serious and a common form of contamination. The handling of a dirty legrope after washing the hands, also may undo much careful work. As soon as milking is completed, cleaning should commence, the bulk of the cleaning being done before taking the equipment to pieces. Wash away any dirt that may have accumulated on the outside of the cups, then suck warm water (not hot) through the cups, tubes, and pipes, completely flushing the whole of the milk system. Insert the brush or ball of horsehair supplied into the milk pipe and allow it to be drawn through the whole length three or four times. Now draw through each set of teat cups at least one gallon of the caustic soda solution which has been heated to boiling point, holding the cups in such a way that the suction will tbe distributed evenly through each. The caustic solution must now be flushed out by drawing at least two gallons of boiling water through each set of cups. Boiling water is necessary at this stage, because not Only are the germs associated with milk production rendered inert, but the evaporation of all surplus moisture throughout the system is effected.

After steaming or scalding, leave the pipe line open at both ends, which will allow the free circulation of air through the pipe and aid drying. The air system, with its pipe, vacuum tank, and releaser, must receive attention also. Draw the soda solution through, and follow this with boiling ■water, paying particular attention to the cleaning of the pipe connecting the releaser and the vacuum tank, by flooding the releaser to cause the water to travel through to the vacuum tank. This is important. Open the vacuum tank and allow the circulation of air. disconnect the releaser, and wash. Do not neglect the vacuum system. Special attention must be paid to all joints and connexions throughout the plant. ' COW RUGS from 6 0 Unlined, ! 8/- Half-lined at MATSON'S. The action of the soda solution on ♦he inner surface of the rubbers is to form, within a short time, a glass-like surface. The milk-fat» which, like all fat, is damaging to rubber, is removed. If- this operation is not carried out daily the rubbers, will become spongy and form harbours for germs. Rubber tubing' and teat inflations if examined closely may indicate the presence of cracks and crevices ■which accumulate dirt, and are sources of infection. The use of hard brushes or scrapers is not recommended, as the inner surface of the rubber becomes scored, and is consequently hardjr to keep clean. The outside as well as the inside should receive attention, and when washed placed in clean, airy surroundings. It is advisableJo keep rubbers away from strong light. In washing utensils that have contained milk or cream..the first washing should be with warm water, at blood heat. The use of hot or boiling water hardens the casein and albumen which forms a coating on the vessel, making it very difficult to remove. For buckets and cream cans first wash trith warm water, then with boiling water and soda, following with a rinsing with boiling water. These vessels should then be drained and kept In a cool, airy, well-lighted place. Too much attention cannot be paid to cleanliness, and a little carelessness In one direction may render the resl at one's efforts useless. jL MATSON and CO.
