While hanging here the carcases are all carefully cleaned, and all superfluous fat, &c, that may remain on them after passing-through the 'butcher's bands removed." On the arrival of the vans at Port Chal mers they are drawn up alongside the vessel, and the carcases are passed out into the " 'tween-decks, " in which the temperature is kept so low as to partially freeze them only. The two boilers attached to the apparatus are each capable of bearing a pressure of 1601 bto the square inch, but each one in ordinary working is kept at 601 b, a pressure quite sufficient for the purpose. The engines are fitted with four cylinders, all on one bed-plate — one steam, one expansion and compressing cylinders ; each is 21in in diameter, the stroke is 24in, and 60 revolu tions are made to the minute. The temperature maintained between decks is, as we have said, enough to freeze the carcases skin-deep. Here they are hung (some slight distance apart) for 24 hours, during which time they cool gradually, and are each sown into a coarse calico bag. At tbe expiration of this time they arc shifted into the lower hold, where they are packed bead and tail as closely as they can be stowed, and the real freezing is here performed. The engines on board the Dunedin can, if required, maintain the temperature here considerably below zero, but 28 degrees is found to be all that is required for the voyage. The meat is thoroughly frozen after remaining here for 24 hours, and a visit to this part of the vessel is disagreeably suggestive of an Arctic expedition. The hold is of course rendered air-tight by closely-fitting doors, and on entering from a comparatively warm atmosphere tbe visitor is (not figuratively) " chilled to the marrow of his bones." The meat is ranged closely and symmetrically on either side, andis reduced to such a state of frigidity that on being tapped it emits the hard hollow sound of a mass of timber. The iron stanchions, moreover, are coated with a thin layer of frost that renders the touch exceedingly uncongenial ; and the ceiling is similarly adorned, although in much greater quantity. Underfoot, however, this is varied by actual snow, which lies preetty thickly in tbe open space, and can be gathered into a solid mass.
