REFRIGERATOR VESSELS.--On board the fastest steamships plying between our Atlantic ports and Europe, are found extensive refrigerator compartments. Dressed beef and mutton are exported in large quantities, as well as fruits, vegetables, dairy products and oysters. The temperature, for meat, is maintained a few degrees below the freezing point. Air machines are principally used on the ocean, the brisk circulation of air which they maintain being an advantage. The enormous quantities of dressed meat transported from the United States, Argentine, New Zealand and Australia, to Europe, requires a large fleet of steamers, some of which are equipped, at considerable expense, for this special service. In connection with these vessels, at both shipping and receiving wharfs, are large storehouses, where the frozen meat is held, awaiting shipment, or received after its voyage. IN TRANSPORTING FRUIT ON THE OCEAN, a large fleet find employment; in it are found steamers built with insulated hulls formed by lining the outer steel hull with wood and packing the inclosed space with powdered charcoal. Refrigerator service is essential to success in transporting the more delicate fruits such as pears, peaches, cherries and plums which have been landed in London from California and South Africa in excellent condition in this way. Ventilation, in connection with insulated hulls, is depended on in handling most of the tropical fruits imported into this country. Bananas from Central and South American and West India ports form the staple commodity, giving employment to an extensive fleet of very excellent boats. From Southern Europe large quantities of fruit are exported, oranges, lemons, grapes and nuts forming the bulk of the shipments which are carried in steamers in well ventilated compartments. The development of the fruit traffic from different districts is attaining huge proportions with the control of the proper conditions for transit which shippers now have within their reach. Fruit shipments are now made to England from Florida and California, Southern Europe, South Africa and Australia. The shipments from one land forming the complement of those from others, a continual supply of the finest fresh fruits is available. ICE IN THE FISHERIES.--It is now long ago that fresh fish were to be enjoyed only at places near by the fishing grounds. Now they are in the market the year round. During the season when fish may be caught, those not entering into immediate consumption are placed in cold storage rooms and frozen, to be taken out at any later time as they are wanted. Such storage houses are found in connection with all important fishing stations on the New England coast, along the great lakes, and among the salmon fisheries of the Northern Pacific. When the fishing boats start on a cruise they are loaded with ice, with which the fish are preserved, and the fishermen are not obliged to return home with a small catch to prevent its spoiling.
