The New Zealand Shipping Company's barque Mutaura arrived at Lyttelton yesterday from London, after baring been fitted with a refrigerator to enable her to he placed in the fresh meat trade between this country and the United Kingdom. A* will he remembered, the BeU Coleman refrLerafor was the first tried by oceangoing reueU in the meat-carrying trade, but ie would seem that the patent to be ween on board the Mitaura, and called Haslam's diy air refrigerator, is superior in many respect* to the Beil-Coleman fretztnsr procew. The Orient Steim Navigation Company, the Cunard Shippirg Company, the Brisbane Meat Preferring Company, th j Dunlin Meat Compaf j, and several other companies hare adopted their patent in preference. 'I he fallowing comments are from Home papers, and may at this time be of interest in connection with the practical tests nf the Haslam method of freezing. The Times of October sth, last year, «ays : " Three ressels of the Orient Line are fitted with refrigeratoiu — the Cuz;o with the Bell C^leman michine, and the Garonne and the Orient with the H«lim machine. The difference in the machines U th*t in the former the process of freezing is by means of wet air. and in the latter by dry air only. Mr Alfred S. Haslam, of the Ha*lam Foundry and Engineering Company, Derby, the patentee, placed the machine in the Orient previous to her outward passage. Mr Haslam came to Plymouth for the express purpose of ascertaining the result of the experiment. In company with Mr Sett, the chief engineer of the Orient, Mr Haslam inspected the refrigerating machinery and the chambers in which the meat was located. The machine, which had been kept going twenty out of the twenty-foar hours during the whole pwaije, excepting in passing the Suez Cuml, when it was continually run, adj >in« the engines of the vessel. It takes up very little space. The atmosphere with the engine at work was decidedly close. Into the machine a.d refrigerator water and air may enter at 90 degrees. Further, the air, being c impressed to about 40'b per squire inch <»nd heited to about 280 degrees, is then parsed through the refrigerator and expanded, leaving the machine at a temperature ranging from 40 to 60 degrees below z*»ro. Regularly the machine dischargee a volume of atr at the rate of 40,000 cubic feet per hour at an average temperature of 40 degrees below z^ro. When refrigerating with water at 90 degrees Fahrenheit, pure dry air is delivered int-> the chambers 40 to 60 degrees below aero. A similar degree of cold i* to be obtiined with water Ht 50 degrees Fahrenheit. It is a most important point to know that the extreme heat of the tr->pic# does not interfere with the freezing prices?." The Daily y<>.cs> of the same date, lays: "The principle on which the Haslam Refrigerators manufacture cold air will be understood by practical engineers when we a%y that it ii that of surface cooling in heu of the older system of j-it cooling. Water and air having entered the machine, the air is compressed at about 451b to the square inch, heated | co about 280 degrees, then pissed through tho refrigerator and expanded, upon which the volume of cold air, which may ' even be produced at so low a range a* from 40 decrees to 60 degrees below zero, discharges itself continuously into the cloied chambers in which the meat or other perishable articles are stored. Its chief feature is the production of a preservative dry air. Another point is that the same degree of cold, |we are assured, can be obtained with water taken in at 90 degrees i as with water taken in at 50 degrees, a matter of obvious importance in ships which have to p»*s through the tropics, . . . A very little examination of the practical working <>f the refrigerator, and of its results, soon convinces the visitor that the temperature of the external air is really a matter of complete indifference. The hottest sun that ever shone down from a tropical sky would still leare the i meat room cold as the air of a bright, S hard, frosty night in the coldest winter of these latitude*. 11 S'>»*kmg f.f the Gtronne's arrival, the London Stamford of October 25ih says : " The Garonne »t fitted with the refnge- W rating machine patented by the Haslam | Foundry and Engineering Company, of Derby, and the ohief engineer of the vessel reports that the apparatus has worked satisfactorily and is capable of reducing the temperature to several degrees below the requisite cold, so that in the tropic? not the slightest difficulty wai experienced in keeping the temperature down to the point requisite for the preservation of the meat." The refrigerator on board the Mataura was worked a sufficient part (sometimes one hour, at others two hours) of each day on the toyage, and the report of the chief engineer, Air Scott, fully corroborates these eminently satisfactory reports.
